Changes and New Features in 15.09:
* ESS[R]: The indentation logic has been refactored. It should be
faster, more consistent and more flexible. There are three types
of indentation settings, those starting with 'ess-offset-' give the
actual offsets, those starting with 'ess-indent-' are control
(commonly Boolean) variables, and those starting with 'ess-align-'
are vertical alignment overrides which inhibit default offsets in
specific situations. See 'ess-style-alist' for detailed
description of the new indentation system and provided default
indentation styles.
* ESS[R]: Deprecation of old indentation settings. As a consequence
of the indentation re-factoring 'ess-brace-imaginary-offset',
'ess-expression-offset' and all delimiter-specific offsets are
deprecated. The settings for indentation of continued statements
have been replaced by 'ess-offset-continuations'. It can be set to
either 'cascade' or 'straight' (the default).
'ess-arg-function-offset' has been replaced by
'ess-indent-from-lhs' and has been generalised to assignments.
This setting now works with both statement blocks and expressions
and only takes effect for offsets set to 'prev-call' and
'open-delim' in order to produce a consistent indentation.
* ESS: A test framework has been set up.
* ESS[R]: A new RStudio style is provided to mimic as closely as
possible R files indented via RStudio. To reproduce the setup of
some of the RStudio users, the RStudio- style with
'ess-offset-arguments' set to 'prev-line' is also provided. In
addition, the new RRR+ style is equivalent to RRR except it indents
blocks in function calls relatively to the opening delimiter. This
style does not try to save horizontal space and produces more
indentation.
* ESS[R]: Roxygen fields will now be indented on paragraph refilling
in order to make the documentation more readable. You can also
refill commented lines in the 'examples' field without squashing
the surrounding code in the comments.
* ESS[R]: ESS can now format your code! This is controlled through
the settings 'ess-fill-calls' and 'ess-fill-continuations'. When
activated, '(fill-paragraph)' formats your calls and your
formulas/continuations while making sure they don't go past
'fill-column'. Repeated refills cycle through different styles
(see the docstrings for more details). By default, the refilled
region blinks. Set 'ess-blink-filling' to nil to prevent this.
* ESS[R]: Fix occasional missing error location fontification in
inferior buffers.
* ESS[R]: ess-developer now correctly assigned the environment of new
functions to the package namespace.
* ESS[Julia]: ?[topic] now works in the *julia* buffer. Note that
support for editing Julia code now depends on 'julia-mode.el' from
the Julia project. If you install ESS from the official
tarball/zip file, 'julia-mode.el' is already included. Otherwise,
if you install ESS by running 'make', then the latest version of
'julia-mode.el' is downloaded (and so you need an active internet
connection to install) during the installation process.
Alternatively, if you run ESS without running 'make', then ensure
that you have the 'julia-mode.el', which you can get easily from
MELPA for example.
* iESS: For naming inferior processes, ESS can use 'projectile''s
project root and it does so when
'ess-gen-proc-buffer-name-function' is set to
'ess-gen-proc-buffer-name:projectile-or-simple' as by default, or
to another value beginning with
'ess-gen-proc-buffer-name:projectile-*'.
Changes and New Features in 15.03-1:
* ESS[R]: An indentation bug has been fixed (github issue 163)
* ESS[R]: On windows, if 'ess-prefer-higher-bit' is non-nil (the
default), then R-newest will try to run a 64 bit (rather than 32
bit) version of R.
Changes and New Features in 15.03:
* ESS[R]: Full native support for 'company-mode'.
* ESS[R]: More efficient caching algorithm for R completion.
* ESS: New offset variable 'ess-close-paren-offset' to control the
indentation of the closing parentheses.
* ESS[R]: Ask for CRAN mirror only once per emacs session.
* ESS[R]: Detect 'library' and 'require' calls for better completion
caching.
* Buffer display is now customizable ('ess-show-buffer-action').
* Use 'y-or-n-p' instead of 'yes-or-no-p' throughout.
* More support for ODS in ess-sas-graph-view.
* Makefiles are now both UNIX and GNU friendly.
* ESS[R]: Simplify directory lookup in 'ess-developer' (#137).
* Make closed paren indentation consistent
Bug Fixes in 15.03:
* Fix open brace indentation bug (#27 in ess/R-ESS-bugs.R).
* Fix git version lookup
* Don't check directory modtime in R dialect.
* Declare all ess macros for edebug.
* Add 'ess-smart-comma' to eldoc message functions.
* Inform users when retrieving RDA aliases.
* Line ending in '~' is also a continuation line.
* Filing roxy paragraphs works as expected now.
* In 'ess-developer-add-package', remove incorrect 'wait' argument
from 'ess-get-words-from-vector' call.
* Fix #96, #117, #120, #125, #134, #137.
* Fix ess-quit-r. Call base::q() even if it is masked.
* Fix 'ess-show-buffer' to always display the buffer in another
window.
* Makefile: Fix cd bug for directories with spaces in them
* 'ess-kill-buffer-and-go' modified to not restart R
Changes / Selected Bug Fixes in 14.09:
* ESS[Julia]: Executable is changed to 'julia'.
* ESS[Julia]: Completion and help system was adjusted to Julia
v.0.3.0. Julia v.0.2.x is no more supported.
* ESS[R]: Running R with 'gdb' debugger now works as expected
* iESS: Inferior ESS buffers are now derived from 'comint-mode'
* ESS[R]: 'ess-execute-screen-options' uses correct screen width in
terminal sessions
* ESS: 'ess-build-tags-for-directory' works when no TAGS file name
was provided
* ESS: 'ess-offset-statement-continued' is now respected everywhere
except inside of the 'if' test condition.
* ESS: New variable 'ess-offset-statement-first-continued' for
indentation of the first line in multiline statements.
* ESSR: Starting ',' in multiline statements indentation is now
ignored to achieve a more pleasant alignment.
* ESSR: Improved behavior of 'RET' in roxygen blocks.
* ESS[R]: command cleaning with 'C-u C-u C-y' was broken with lines
containing " + "
* ESS[R]: fixed "empty watch window bug"
* ESS[R]: don't ask for help location on ac-quick-help (request of
github #81)
* ESS[R]: "importClassesFrom" and "importMethodsFrom" were added to
the list of two-parameter roxygen commands
* ESS[R]: fix vignetes display and hyperlinks (were broken in
13.09-1)
* ESS[Julia]: recognize function names ending with !
* ESS[Julia]: fix indentation of "for" comprehension syntax within
brackets.
Changes / Selected Bug Fixes in 13.09-1:
* ess-remote and TRAMP: R support code is now downloaded in binary
form instead of being injected from local machine. The R code is
stored in '~/.config/ESSR/' directory on the remote machine
* TRAMP: PAGER environment variable is now correctly set to
'inferior-ess-pager'
* retrieval of help topics on remote machines is fixed
* org-babel: source references of R code executed from org files
correctly point to source references in original org files (version
8.2.1 or higher of org-mode is required for this feature)
* 'ess-execute' is now bound to 'C-c C-e C-e' in 'ess-extra-map'.
* completion works again in 'ess-execute'
* ESS[R]: 'head' and 'tail' methods were replaced by '.ess_htsummary'
in 'ess-R-describe-object-at-point-commands'
* ESS[roxygen]: evaluation commands now work in roxygen blocks.
Leading comments are automatically removed before the evaluation
* ESS[transcript]: 'Clean Region' now works with multiline
statements; 'ess-transcript-clean-region' etc. correctly treat
multiline statements, i.e., no longer forgets the lines typically
preceded by '+'
* ESS[SAS]: Three features/fixes with special thanks to Matthew
Fidler https://github.com/emacs-ess/ESS/pulls/mlf176f2
(https://github.com/emacs-ess/ESS/pulls/mlf176f2). Turn on SAS log
mode when appropriate. Indent comments and CARDS statement more
appropriately.
* ESS[SAS]: 'ess-sas-edit-keys-toggle' default returns to 'nil'
* ESS[R]: support for 'prettify-symbols-mode': contribution from
Rudiger Sonderfeld <https://github.com/emacs-ess/ESS/pull/65>
* ESS[SWV]: knitr now evaluates in the current frame
* ESS[developer]: ess-developer doesn't kill open DESCRIPTION files
anymore
* ESS[roxygen]: 'ess-roxy-preview-HTML' is now on 'C-c C-o C-w' and
'ess-roxy-preview-text' is now on 'C-c C-o C-t'
* ESS: installation with 'make install' was simplified and should
work out of the box on most *nix systems
* ESS installation instructions simplified
* fixed font-lock bug introduced in 13.09 that was causing very slow
process output
Changes/New Features in 13.09:
* font-lock in process buffers doesn't "spill" over prompts. Missing
closing string delimiters should not cause wrong fontification of
the following command input.
* ESS[julia]: full features M-TAB completion and auto-complete
support, which now works for modules, structures and data types.
* ESS[julia]: a much better eldoc showing arguments of methods and
data type constructors
* ESS-developer:
- ESS-developer work-flow pattern has been streamlined:
ESS-developer is now automatically activated on per-file basis
if the file is part of a developed package
'ess-developer-packages'. The old behavior (activation on
per-process basis) is still available on 'M-x ess-developer'
in a process buffer.
- integration with 'devtools' package. New command
'ess-developer-load-package' calls 'load_all' on the package
containing current file. 'ess-developer-add-package' now
offers IDO menu completions with available loading methods,
currently 'library', and 'load_all'. Loading command can be
customized with 'ess-developer-load-on-add-commands'.
* 'TAB' now indents region if region is active (a contribution of
Matthew Fidler in pull #41)
* 'M-x ess-version' now reports full loading path and recognizes git
and ELPA versions.
* warning and error keyword are now highlighted with
'font-lock-warning-face' as they should be, (for quite some time
these keywords have been hijacked by compilation mode
fontification).
* eldoc: Eldoc now recognizes multiple processes. If current process
is busy, or current buffer is not associated with a process, eldoc
picks its completions from the first available free process.
* org-babel: evaluation is now org-friendly
* help: new help buffers now try to reuse ess-help buffers. This
behavior is controlled by 'ess-help-reuse-window' custom variable.
* help: ?foo pops IDO menu on multiple help files (so far it worked
only for 'C-c C-v')
* remote evaluation is considerably faster now on slow connections
* ESS[R] tracebug R source references regular expressions are
(mostly) language agnostic.
* 'ess-function-call-face' inherits from
'font-lock-function-name-face' rather than
'font-lock-builtin-face'.
* 'ess-inject-source' now accepts 'function-and-buffer' option.
* Documentation: The "New Features" section (and 'NEWS') now
represent recent changes: within the last year or so. All changes
can be found in the new news.html (news.html) (or 'NEWS' and
'ONEWS').
* ESS[R] 'ess-rep-regexp' should no longer inf.loop (rarely!), and
hence 'M-x ess-fix-miscellaneous' should neither.
Changes/New Features in 13.05:
* ESS[gretl]: Support for 'gretl' (both editing and sub-process
interaction). A contribution of Ahmadou Dicko.
* ESS: process output display is 4-10 times faster due to new caching
and only occasional emacs re-display (for the moment this
functionality is available only when 'ess-tracebug' is active).
* ESS: 'C-c `' is now bound to 'ess-show-traceback' and 'C-c ~' is
bound to 'ess-show-call-stack'.
* ESS[R]: ESS stores function in 'ESSR' environment to avoid kludging
users' global environment and accidental deletion.
* ESS[R]: new variable 'ess-swv-processing-command' to control
weaving and tangling.
* ESS[R]: 'ess-default-style' has been changed (from 'DEFAULT') to
'RRR'. Use something like '(setq ess-default-style 'DEFAULT)' or
'(setq ess-indent-level 2)' in your '~/.emacs' equivalent _before_
loading ESS, if you do not like this new "incompatible" default
style.
* ESS[julia]: ESS stores its functions in 'ESS' module.
* ESS[julia]: Eldoc is now supported in julia modes
* ESS[julia]: Adjusted error reference detection and interactive help
to julia internal changes
* ESS[R]: 'ess-use-tracebug''s default has been changed to 't'. Set
it to nil if you want to keep the previous behavior.
* ESS[tracebug]: Electric debug keys have been removed [breaking
change] The functionality was replaced with 'ess-debug-minor-mode'
and 'ess-debug-minor-mode-map'.
* ESS[tracebug]: 'ess-tracebug-map' is an alias to 'ess-dev-map' 'C-c
C-t'.
* ESS[tracebug]: 'ess-bp-toggle-state' ('C-c C-t o') can now be used
during the debug session to toggle breakpoints on the fly
(suggestion by Ross Boylan).
* ESS[tracebug]: 'ess-debug-flag-for-debugging' and
'ess-debug-unflag-for-debugging' work correctly from the debugging
contexts. These commands also recognize non-exported functions for
the packages listed in 'ess-developer-packages' ('C-c C-t C-a').
* ESS[R]: Eldoc (activated by 'ess-use-eldoc') has become more
sophisticated, and hence also more intruding in the interface
between the Statistics software, e.g., R, and the user.
Note that you can turn off ElDoc, by placing '(setq ess-use-eldoc
nil)' in your '~/.emacs' file, prior to loading ESS,
* ESS[SAS]: long over-looked 'SAS-mode-hook' appears!
* ESS[SAS]: 'ess-sas-edit-keys-toggle' now defaults to 't' since
'sas-indent-line' is still broken, i.e. 'TAB' is now bound to
'ess-sas-tab-to-tab-stop' by default
Changes/Bug Fixes in 12.09-2:
* ESS: new 'ess-switch-to-end-of-proc-buffer' variable that controls
whether 'C-c C-z' switches to the end of process buffer. The
default is 't'. You can use prefix argument to 'C-c C-z' to toggle
this variable.
* ESS: fix in 'ess-eval-linewise' that was causing emacs to hang
during R debugging with 'ess-eval-visibly' equal to 't'.
* ESS: fix in 'ess-eval-linewise' that was causing emacs to recenter
the prompt in visible window
* ESS[tracebug]: A better handling of "Selection" prompts and debug
related singlekey commands.
* ESS: fix a bug in 'ess-switch-process' that was causing '*new*'
selection to fail.
* ESS[R]: Solve missing 'ess-local-process-name' bug in R-dired.
* ESS[SWV]: 'ess-swv-PDF' doesn't ask for a command to run if there
is only one command in 'ess-swv-pdflatex-commands'.
* ESS[SWV]: 'ess-swv-weave' gained an universal argument to allow for
an interactive choice between available weavers (sweave, knitr).
* ESS: 'ess-eval-*-and-step' functions go to next empty line at eob,
instead of staying at the last line.
Changes/New Features in 12.09-1:
* ESS _Breaking Changes in Keys_:
- New keymaps: 'ess-doc-map' bound to 'C-c C-d'; 'ess-extra-map'
bound to 'C-c C-e'; 'ess-dump-object-into-edit-buffer' was
moved on 'C-c C-e C-d'
- roxygen map was moved on 'C-c C-o' and 'ess-roxy-update-entry'
now resides on 'C-c C-o C-o'
- ess-handy-commands is not bound anymore
- 'ess-dev-map' (including 'ess-tracebug' and 'ess-developer')
moved on 'C-c C-t'
- 'C-c C-y' is deprecated in favor of 'C-c C-z C-z'
* ESS[R] new command 'ess-describe-object-at-point' bound to 'C-c C-d
C-e' (repeat 'C-e' or 'e' to cycle). It was inspired by Erik
Iverson's 'ess-R-object-tooltip'. Customize
'ess-describe-at-point-method' to use tooltip instead of an
electric buffer.
* ESS: New command 'ess-build-tags-for-directory' bound to 'C-c C-e
C-t' for building dialect specific tag tables. After building tags
use 'M-.' to navigate to function and objects definitions. By
default 'C-c C-e C-t' builds tags based on imenu regular
expressions and also include other common languages '.c, .o, .cpp'
etc. But it relies on external 'find' and 'etags' commands. If
'ess-build-tags-command' is defined (for 'R'), the inferior process
is asked to build tags instead.
* ESS: 'ess-switch-process' offers '*new*' alternative to start a new
process instead of switching to one of the currently running
processes.
* ESS: Switching between processes ('C-c C-s') uses buffer names
instead of the internal process names. Use 'M-x rename-buffer'
command to conveniently rename your process buffers.
* ESS: Process buffers can be automatically named on process creation
according to user specified scheme. Default schemes are *proc*,
*proc:dir* and *proc:abbr-long-dir* where 'proc' stands for the
internal process name and 'dir' stands for the directory where the
process was started in. The default is *proc*. For customization
see 'ess-gen-proc-buffer-name-function'.
* ESS: 'ess-eval-visibly-p' is deprecated in favor of
'ess-eval-visibly'.
* ESS: New evaluation pattern 'nowait'. In addition to old 'nil' and
't' values, 'ess-eval-visibly' accepts 'nowait' for a visible
evaluation with no waiting for the process. See 'ess-eval-visibly'
for details on evaluation patterns.
* ESS: New "Process" menu entry with process related commands and
configuration
* iESS: Process buffer is now automatically shown on errors
* ESS: New 'ess-switch-to-inferior-or-script-buffer' command bound to
'C-c C-z' in both script and process buffers. If invoked form
process buffer it switches to the most recent buffer of the same
dialect. It is a single key command.
* ESSR-help: On multiple help pages with the same name, 'C-c C-v' now
asks for user resolution directly in emacs.
* ESS[R] ess-roxy: new variable 'ess-roxy-re' for fontification of
cases where the number of leading '#' differs from 'ess-roxy-str'.
* ESS[R] Eldoc was considerably enhanced. It now finds hidden
default S3 methods and displays non-default methods' arguments
after trailing ||.
* ESS[R]: New 'ess-display-demos' command bound to 'C-c C-d o' and
'C-c C-d C-o'
* ESS: New 'ess-help-web-search' command bound to 'C-c C-d w' and
'C-c C-d C-w' to facilitate interactive search of web resources.
Implemented for 'R', 'Stata' and 'Julia'. See also
'ess-help-web-search-command'.
* ESS: ess-pdf-viewer-pref accepts now command line arguments
* ESS[Rnw]: Add knitr support. Customize 'ess-swv-processor' for the
default processor.
* ESS[Rnw]: More thorough renaming of remaining 'noweb-*' to
'ess-noweb-*'.
* ESS[Rnw] new commands 'ess-eval-chunk-and-step' and
'ess-eval-chunk' bound to 'M-n C-c' and 'M-n C-M-x' to mirror
standard ess commands in C-c map.
* ESS[R] Auto-completion: new variable 'ess-ac-R-argument-suffix' to
customize the insertion of trailing "=". Defaults to " = ".
* ESS[Julia]: Added index, apropos and web-search to julia.
* ESS help: More evaluation commands were added to ess-help mode
('C-c C-c', 'C-M-x' etc)
Bug Fixes in 12.09-1:
* iESShelp: Multiple help pages with the same name are properly
handled on 'C-c C-v'
* iESSremote: Evaluation with ESS remote no longer freezes emacs.
* iESS: 'comint-previous-prompt' 'C-c C-p' no longer stops on
secondary prompt "+".
* iESS[R], iESS(Sqpe) [S] on Windows: The 'options("editor")' is now
initialized to 'emacsclient' instead of the previous 'gnuclient'.
The user may need to add the line '(server-start)' to the emacs
initialization file. 'emacsclient' has been included with emacs
since GNU Emacs 22.1.
* ESS[Rnw] Fixed "connection to R" bug (in 12.09 only).
* ESS[Rnw] Explicit 'ess-swv-stangle' and 'ess-swv-sweave' functions.
* ESS[Rnw] Fixed completion and smart underscore problems cause by
unmatched "\"'
* ESS[R] is more careful with the 'R' code injection. It now happens
only once at the start of the session.
* ESS[R]: Fixed auto-scrolling the comint buffer on evaluation.
* ESS[Julia]: Solve several indentation and word navigation problems.
* ESS[Julia]: Help system works again.
Changes/New Features in 12.09:
* Due to XEmacs lacking some features that ESS requires, ESS support
of XEmacs ends with ESS 12.04-4. This decision will be re-visited
in the future as XEmacs continues to sync with GNU Emacs.
* ESS[R]: On Windows, there is now a new customizable variable
(currently called 'ess-directory-containing-R') to tell ESS where
to look for the 'Rterm.exe' executables. The name of the variable
and the values it can take are both in beta and subject to change.
Prior to this variable, ESS searched only in the default
installation directory. Setting this variable now tells ESS how to
find 'Rterm.exe' executables when they are installed somewhere
else.
* ESS[julia]: _new_ mode for editing julia code ('*.jl'). Start with
'M-x julia'.
Full interaction interface, imenu and basic error referencing are
available.
* ESS[R] noweb: 'noweb-mode' and 'noweb-font-lock-mode' have been
renamed to 'ess-noweb-mode' and 'ess-noweb-font-lock-mode' to avoid
conflicts with the "real" 'noweb-mode'.
* ESS[R] noweb: The long standing font-lock bug has been solved in
'ess-noweb' interface.
* ESS: Basic evaluation keys are now bound to 'ess-eval-region-*-'
functions:
- 'C-M-x' is bound to 'ess-eval-region-or-function-or-paragraph'
- 'C-c C-c' is bound to
'ess-eval-region-or-function-or-paragraph-and-step'
- 'C-RET' is bound to 'ess-eval-region-or-line-and-step'
Each of these functions first evaluates the region whenever the
region is active.
* ESS: 'C-M-a'/'C-M-e' now step to beginning/end of paragraph if no
function has been detected.
* ESS: 'ess-eval-*-and-step' family of functions are now smarter, and
don't step to end of buffer or end of chunk code ('@') when at the
end of the code.
* ESS: 'ess-handy-commands' function is bound to 'C-c h'
* ESS: ESS is now _blinking_ the evaluated region. Set
'ess-blink-region' to nil to deactivate; 'ess-blink-delay' gives
the duration of the blink. Evaluated region is "blinked" in
'highlight' face.
* ESS[R-help] New key 'a' for "apropos()" in help buffers. Also
available through 'C-c h'.
* ESS[R-help] All R commands of type foo?bar and foo??bar are
recognized and redirected into appropriate *ESS-help* buffers.
* ESS[R]: New customization interface for _font-lock_.
ESS font-lock operates with predefined keywords. Default keywords
are listed in 'ess-R-font-lock-keywords' and
'inferior-R-font-lock-keywords', which see. The user can easily
customize those by adding new keywords. These variables can also
be interactively accessed and saved through 'ESS/Font-lock'
submenu.
Several new fontification keywords have been added. Most notably
the keywords for highlighting of function calls, numbers and
operators.
* ESS[R]: auto-complete is now activated by default whenever
auto-complete package is detected. Set 'ess-use-auto-complete' to
nil to deactivate.
* ESS[R]: R AC sources are no longer auto-starting at 0 characters
but at the default 'ac-auto-start' characters.
* ESS no longer redefines default ac-sources, but only appends
'ac-source-filename' to it.
* ESS: 'ac-source-R' now concatenates " = " to function arguments.
* ESS: Menus for ESS and iESS have been reorganized and enriched with
_Tracebug_ and _Developer_ submenus.
* ESS[R]: 'ess-developer' and 'ess-tracebug' commands are available
by default in 'ess-dev-map' which is bound to 'C-c d' in ESS and
iESS maps.
* ESS[R]: 'eldoc' truncates long lines whenever
'eldoc-echo-area-use-multiline-p' is non-nil (the default). Set
this variable to t if you insist on multiline eldoc. See also
'ess-eldoc-abbreviation-style'.
* ESS[R]: completion code pre-caches arguments of heavy generics such
as 'plot' and 'print' to eliminated the undesirable delay on first
request.
* iESS: Prompts in inferior buffers are now highlighted uniformly
with 'comint-highlight-prompt' face.
* ESS[R]: R process no longer wait for the completion of input in
inferior buffer. Thus, long running commands like 'Sys.sleep(5)'
no longer stall emacs.
* ESS: [R, S, Stata, Julia] have specialized 'ess-X-post-run-hook's,
which are run at the end of subprocess initialization.
* ESS[Stata]: All interactive evaluation commands work as expected.
On-line comments are removed before the evaluation and multiline
comments are skipped on 'C-c C-c' and other interactive commands.
* ESS no longer auto-connects to a subprocess with a different
dialect than the current buffer's one.
* ESS: 'ess-arg-function-offset-new-line' is now a list for all the
ESS indentation styles, which results in the following indentation
after an open "(":
a <- some.function(other.function(
arg1,
arg2)
* ESS[SAS]: Improved MS RTF support for GNU Emacs; try
'ess-sas-rtf-portrait' and 'ess-sas-rtf-landscape'.
Changes/Bug Fixes in 12.04-3:
* ESS: basic support for package.el compatibility
* ESS[R]: correct indentation of & and | continuation lines
* 'M-x ess-version' shows the svn revision even after 'make install'
* ESS[SAS]: improved XEmacs support
* iESS[R]: better finding of previous prompt
* ESS[Stata]: adjusted prompt for mata mode
* ESS[R]: resolved name clashes with cl.el
* ESS[R]: removed dependence on obsolete package assoc
* New 'make' target 'lisp', to build the Lisp-only part, i.e., not
building the docs.
Changes/New Features in 12.04-1:
* iESS[Stata]: New interactive help invocation.
* iESS[Stata]: New custom variable 'inferior-STA-start-file'.
* iESS[Stata]: 'inferior-STA-program-name' is now "stata" and can be
customized.
* ESS[Stata] New sections in stata help files Syntax('s-S'),
Remarks('r'), Title('t').
Bug Fixes in 12.04-1:
* ESS[R]: Better 'ess-tracebug' error handling.
* ESS[R]: Corrected 'ess-eldoc' help string filtering and improved
argument caching.
* ESS[R]: Indentation of non-block if/else/for/while lines fixed.
* 'M-x ess-version' should work better.
* ESS: Filename completion now again works inside strings.
* iESS[Stata]: Fixed prompt detection issue.
* ESS[Rd]: R is autostarted also from here, when needed.
Changes/New Features in 12.04:
* ESS: Reverting new behavior of 12.03, 'TAB' in 'ess-mode' no longer
completes by default. If you want smart 'TAB' completion in R and
S scripts, similarly to iESS behavior, set the variable
'ess-tab-complete-in-script' to 't'. Also see
'ess-first-tab-never-complete' for how to customize where first
'TAB' is allowed to complete.
* ESS: completion is consistently bound to 'M-TAB' (aka 'M-C-i') in
both Emacs23 and Emacs24.
* ESS: The variable 'ess-arg-function-offset-new-line' introduced in
ESS(12.03) now accepts a list with the first element a number to
indicate that the offset should be computed from the indent of the
previous line. For example setting it to '(2) results in:
a <- some.function(
arg1,
arg2)
Changes/New Features in 12.03:
* ESS indentation: new offset variable
'ess-arg-function-offset-new-line' controlling for the indentation
of lines immediately following open '('. This is useful to shift
backwards function arguments after a long function call expression:
a <- some.function(
arg1,
arg2)
instead of the old
a <- some.function(
arg1,
arg2)
If '(' is not followed by new line the behavior is unchanged:
a <- some.function(arg1,
arg2)
This variable should be set as part of indentation style lists, or
in ess-mode hook.
* ESS[R]: 'C-c .' sets (indentation) style.
* ESS: In ESS buffers 'yank'('C-y') command accepts double argument
'C-u C-u' to paste commands only. It deletes any lines not
beginning with a prompt, and then removes the prompt from those
lines that remain. Useful to paste code from emails,
documentation, inferior ESS buffers or transcript files.
* Documentation: ESS user manual has been rearranged and completed
with several new chapters and sections to reflect newly added
features ("Completion", "Developing with ESS", "ESS tracebug", "ESS
developer", "ESS ElDoc", "IDO Completion" and "Evaluating Code")
* RefCard: Reference card was updated to include new features.
* Eldoc: Eldoc was rewritten and is activated by default. See
'ess-use-eldoc', 'ess-eldoc-show-on-symbol',
'ess-eldoc-abbreviation-style' variables for how to change the
default behavior. _Note:_ 'skeleton-pair-insert-maybe' prohibits
eldoc display, on '(' insertion.
* ESS[R]: Eldoc shows arguments of a generic function whenever found.
* ESS: 'TAB' in 'ess-mode' now indents and completes, if there is
nothing to indent. Set 'ess-first-tab-never-completes-p' to 't' to
make 'TAB' never complete on first invocation. Completion
mechanism is similar to the completion in the 'inferior-ess-mode' -
a filename expansion is tried, if not found ESS completes the
symbol by querying the process.
* ESS for emacs version 24 or higher: ESS is fully compatible with
the emacs 24 completion scheme, i.e. all the completion is done by
'completion-at-point'. Also in accordance with emacs conventions,
ESS doesn't bind 'M-TAB' for emacs 24 or higher. 'M-TAB' calls the
default 'complete-symbol'.
* ESS[R]: Out of the box integration with 'Auto Completion' mode
http://cx4a.org/software/auto-complete
(http://cx4a.org/software/auto-complete) . Three AC sources
'ac-source-R-args', 'ac-source-R-objects' and 'ac-source-R' are
provided. The last one combines the previous two and makes them
play nicely together. Set 'ess-use-auto-complete' to 't' to start
using it. Refer to documentation string of 'ac-use-auto-complete'
for further information.
* ESS[R]: New unified and fast argument completion system, comprised
of 'ess-funname.start', 'ess-function-arguments',
'ess-get-object-at-point'. Eldoc and auto-completion integration
are using this system.
* ESS: 'ess-switch-to-end-of-ESS'('C-c C-z'), and
'ess-switch-to-ESS'('C-c C-y'): Automatically start the process
whenever needed.
* ESS[R]: 'roxy' knows about previewing text version of the
documentation. Bound to 'C-c C-e t'.
* ESS[R]: Solved the "nil filename" bug in roxygen support.
* ESS[R]: 'ess-tracebug' is now part of ESS:
New Features:
- Source injection: Tracebug now can inject source references on
the fly during code evaluation, i.e. you don't have to source
your file, but just evaluate your code in normal fashion.
Variable 'ess-tracebug-inject-source-p' controls this behavior
- if t, always inject source reference, if ''function', inject
only for functions (this is the default), if 'nil', never
inject.
During the source injection the value of 'ess-eval-visibly' is
ignored.
- Org-mode support: Visual debugger is now aware of the
temporary org source editing buffer ('C-c '') and jumps
through this buffers if still alive, or in original org buffer
otherwise.
- New keys in watch mode: '?' and 'd'
- Two new hooks: ess-tracebug-enter-hook and
ess-tracebug-exit-hook
* ESS[R]: New package 'ess-developer' to evaluate 'R' code directly
in the package environment and namespace. It can be toggled on and
off with 'C-c d t'. When 'ess-developer' is on all ESS evaluation
commands are redefined to evaluate code in appropriate
environments. Add package names to the list of your development
packages with 'C-d a', and remove with 'C-d r'. Source the current
file with 'C-d s'.Evaluation function which depend on
'`ess-eval-region'' ask for the package to source the code into,
'ess-eval-function' and alternatives search for the function name
in the development packages' environment and namespace and insert
the definition accordingly. See the documentation section
"Developing with ESS/ESS developer" for more details.
* ESS[R] help system:
New Features:
- 'q' quits window instead of calling
'ess-switch-to-end-of-ESS'. This is consistent with emacs
behavior help and other special buffers (_breaking change_).
- 'k' kills window without asking for the name (pointed by Sam
Steingold)
- Help map inherits from 'special-mode-map' as suggested by Sam
Steingold.
- Package index: new function 'ess-display-index' bound to 'i'
in help mode map.
- Package vignettes: new function 'ess-display-vignettes' bound
to 'v' in help mode map.
- Display help in HTML browser: new function
'ess-display-help-in-browser' bound to 'w' in help mode map.
It depends on 'R''s 'browser' option.
- New custom variable 'ess-help-pop-to-buffer': if non-nil ESS
help buffers are given focus on display. The default is 't'
(_breaking change_).
- New menu entries for the above functions.
- Bogus help buffers are no longer generated by default, i.e.
buffers of the form "No documentation for 'foo' in specified
packages and libraries: you could try '??foo' ".
'ess-help-kill-bogus-buffers' now defaults to 't'. Beware,
there may be instances where the default is unsatisfactory
such as debugging and/or during R development. Thanks to Ross
Boylan for making the suggestion, Sam Steingold for reminding
us of this variable and Martin Maechler for the warning.
* ESS now uses 'IDO' completing read functionality for all the
interactive requests. It uses ido completion mechanism whenever
available, and falls back on classical completing-read otherwise.
You can set 'ess-use-ido' to nil if you don't want the IDO
completion. See the documentation string of 'ess-use-ido' for more
information about 'IDO' and ESS configuration.
* ESS[S]: "','" is bound to ess-smart-comma: If comma is invoked at
the process marker of an ESS inferior buffer, request and execute a
command from '`ess-handy-commands'' list. If
'ess-R-smart-operators' is t '`ess-smart-comma' also inserts " "
after comma.
* ESS[S], notably 'R': Variable '`ess-handy-commands'' stores an
alist of useful commands which are called by 'ess-smart-comma' in
the inferior buffer.
Currently containing:
change-directory
'ess-change-directory'
help-index
'ess-display-index'
help-object
'ess-display-help-on-object'
vignettes
'ess-display-vignettes'
objects[ls]
'ess-execute-objects'
search
'ess-execute-search'
set-width
'ess-execute-screen-options'
install.packages
'ess-install.packages'
library
'ess-library'
setRepos
'ess-setRepositories'
sos
'ess-sos'
Handy commands: 'ess-library', 'ess-install.packages', etc - ask
for item with completion and execute the correspond command.
'ess-sos' is a interface to 'findFn' function in package 'sos'. If
package 'sos' is not found, ask user for interactive install.
* ESS: New dynamic mode line indicator: Process status is
automatically reflected in all mode-lines of associated with the
process buffers. Particularly useful for displaying debug status
of 'ess-tracebug' and developer status of 'ess-developer' in all
associated buffers.
* ESS: New 'ess-completing-read' mechanism: ESS uses 'ido'
completions whenever possible. Variable 'ess-use-ido' controls
whether to use ido completion or not. Active by default.
* ESS now supports comint fields for output and input detection.
This feature is not used by default, but might be useful in the
future.
* ESS[S]: New custom variable 'inferior-ess-S-prompt' to customize
prompt detection regular expression in the inferior ESS buffers.
You can customize this variable to enhance comint navigation
('comint-previous-prompt' and 'comint-next-prompt') the inferior
buffers.
* ESS[R]: Internal 'R' completion retrieval
('ess-R-complete-object-name') was rewritten and is faster now.
* ESS is using process plist to store process specific variables, as
opposed to buffer local variables as it was using before. The use
of buffer local variables to store process variables is
discouraged.
* ESS: new functions to manipulate process plists: 'ess-process-get'
and 'ess-process-set'.
* ESS: Internal process waiting mechanism was completely rewritten.
ESS no more relies on prompt regular expressions for the prompt
detection. The only requirement on the primary process prompt is
to end in '> '. This could be overwritten by setting
'inferior-ess-primary-prompt'.
* ESS[S], notably 'R': Saved command history: ESS-HISTORY-FILE now
accepts 't' (default), 'nil', or a file name. By setting it to
'nil' no command line history is saved anymore.
ESS-HISTORY-DIRECTORY now allows to have the history all saved in
one "central" file.
* ESS[R]: more Roxygen improvements.
* ESS[R]: 'C-c .' to set (indentation) style.
* ESS[R]: Functions with non-standard names (for example
'aaa-bbb:cc') are properly handled by font-lock and evaluation
routines.
* ESS[R]:Several regexp bugs (described in etc/R-ESS-bugs.el) were
fixed in 'ess-get-words-from-vector' and 'ess-command'.
Changes/New Features in 5.14:
* ESS[BUGS/JAGS]: Batch BUGS is back! For recent OpenBUGS versions,
3.0.8+, a batch BUGS script is once again available, but for Linux
only. Therefore, since it seems that BUGS and JAGS must co-exist
(rather than a transition from BUGS to JAGS), .bug files are now in
ESS[BUGS] mode and .jag files are in ESS[JAGS] mode. ESS[BUGS] now
works like ESS[JAGS] rather than the original mode ESS[BUGS] mode
which was difficult to maintain. Although, ESS[BUGS] appears to
work, there still may be some features missing as well as bugs.
* ESS[R]: New customizable variable 'ess-swv-plug-into-AUCTeX-p'
Commands to Sweave current file and LaTeX the result are now
available to AUCTeX users, if this variable is set to 't'.
* ESS[S]: 'C-c C-c' ('ess-eval-function-or-paragraph-and-step') is
now skipping over comments as the other paragraph functions do. It
(and similar functions) should no longer wrongly find 'function()'
beginnings inside comments or strings.
* ESS[SAS]: improved by better support for GNU Emacs
Changes/New Features in 5.13:
* ESS[R]: On Windows, for R 2.12.0 and later, the Rterm executables
(in subdirectories i386 / x64) now are found as well as for earlier
R versions.
* ESS[S+]: on Windows, both 32- and 64-bit versions of S+ ("S-PLUS")
are found now and made available on the menu.
* ESS[R]: When prompting for a starting directory, the R version is
(always?) correct now.
* ESS[R]: on non-Windows platforms, the 'use-dialog-box' variable is
no longer temporarily changed (to 'nil' for R-x.y.z version
functions and to 't' for 'R' itself), but rather the user
customization is obeyed.
* ESS[R]: more Roxygen improvements.
* 'Rd-preview-help' now generates preview buffers with navigation
facilities the same as regular help buffers.
* ESS: New functions and keys C-c [up] / [down] for evaluating the
buffer "from beginning till here".
Changes/New Features in 5.12:
* ESS[SAS] Font-locking: update of PROCs keywords (up to SAS 9.22);
error/warnings.
* ESS[R]: Roxygen improvements: S4 classes; also optionally keep
spaces when filling arguments
* ESS[Rd]: support new keywords: section-name \subsection plus a
dozen "new" keywords; should match R 2.12.x now.
* 'ess-display-help-on-object' ('C-c C-v') now _caches_ the list of
topics, thus speeding up the improvement feature introduced in 5.9.
Changes/New Features in 5.11:
* Filename completion within buffers now adds only trailing
characters to complete the filename, rather than expanding to an
absolute file path. This filename completion is bound to the TAB
key.
* 'M-n P' in Sweave buffers now prompts for the command to run
instead of using 'pdflatex' unconditionally, offering completion
from customizable collection 'ess-swv-pdflatex-commands', the first
of which is taken as default and that defaults to 'texi2pdf'.
* 'M-RET' is now also bound in S language (R and S+) buffers to
'ess-use-this-dir'. It sends 'setwd(..)' to the S process to set
the working directory to the one of the source file.
Changes/New Features in 5.10:
* 'M-RET' in *S* buffers is now bound to 'ess-dirs'. This function
will set Emacs's current directory to be the same as the *S*
process. This is useful if you use 'setwd()' within a *S* process.
Changes/New Features in 5.9:
* Toolbar: The toolbar now has an icon for starting Splus.
* Indentation: New documentation and code has been added to make it
easier to change how ESS indents code. In particular, see
'ess-default-style', 'ess-own-style-list' and the documentation
subsection "Changing indentation styles".
* 'ess-display-help-on-object' ('C-c C-v') now offers completion
candidates for help file aliases, in addition to object names.
* Font locking: is now turned on even without 'window-system' is
'nil', whenever ESS-FONT-LOCK-MODE is non-nil, i.e., by default.
* ESS script editing: ess-eval-deactivate-mark default is now t, as
suggested by Leo Alekseyev and subsequent "unanimous" ESS-help
discussion.
* ESS[R]: Editing support for "#!" (Rscript / littler) editing,
thanks to Jeffrey Arnold.
* ESS[R]: Now finds all R versions, both 64-bit and 32-bit, on some
64-bit Windows machines. Please report back to ess-core success or
failure on your 64-bit Windows machine.
* ESS Manual now more visually pleasing;
<https://ess.r-project.org/Manual/ess.html>
* ESS[R]: Roxygen on XEmacs no longer font locks for now (as it
required missing features and hence broke ESS startup, there).
* ESS[R]: Roxygen has a sub-menu on the [ESS] menu.
* ESS[R]: Function 'ess-rutils-htmldocs' in 'ess-rutils.el' offers an
alternative to 'help.start()' for navigating R documentation, using
the 'browse-url' Emacs function.
Changes/New Features in 5.8:
* ESS[R]: New 'ess-rutils.el' with utilities for listing, loading,
installing, and updating packages, as well as object manipulation
(listing, viewing, and deleting). It also provides an alternative
to 'RSiteSearch()' that uses the 'browse-url' function, so results
can be viewed in an Emacs web browser.
* ESS[R]: much more extensive Roxygen interface, via ess-roxy.el from
Henning Redestig. Ess-roxy supports filling of roxygen fields,
generation and updating roxygen templates, completion of roxygen
tags, basic navigation (marking and moving between entries),
folding using hs-minor-mode and preview of the Rd file.
* Emacs Lisp files have got better names (partly, for now).
Changes/New Features in 5.7:
* ESS[R]: loading a source file ('C-c C-l') now works in Windows,
similarly to other platforms; (further; it had accidentally been
broken in ESS 5.6 on all platforms)
Changes/New Features in 5.6:
* ESS[R]: help() calls have to differ from old default, with newer
versions of R; currently via .help.ESS <- function(...) hack.
Changes/New Features in 5.4:
* ESS[SAS]: The long overdue change from 'make-regexp' to
'regexp-opt' for font-locking is complete. The new 'regexp-opt' is
now the default since it is better than the old code in many ways
(and especially more maintainable). However, there are certainly
some special cases missed (bug reports and patches welcome!).
Setting 'ess-sas-run-regexp-opt' to 'nil' will result in the old
code being used.
* ESS[BUGS] and ESS[JAGS]: typing '=' now results in '<-'.
* ESS[R] function arguments "show" '(ess-r-args-show)' now uses the
new '(tooltip-show-at-point)' contributed by Erik Iverson.
* Toolbar icons now also work in (beta) Emacs 23.
* ESS[S]: New function 'ess-change-directory' for setting both emacs'
current directory and the directory of an *R* or *S* buffer.
* ESS[S] when transient-mark-mode is true, the mark is now kept,
rather than deactivated, thanks to a patch from David Reitter.
Changes/New Features in 5.3.11:
* ESS[SAS]: work around bug in Emacs 22.2 & 22.3 which fails to set
case-fold fontification automatically.
* Rd mode: support new keyword 'Rdversion'
* ESS[R]: now again works with Emacs 21.x
Changes/New Features in 5.3.10:
* Fixed noweb-mode bug accidentally introduced into 5.3.9
* In noweb-mode, e.g., Rnw-mode, electric "<" also inserts closing
"@". Further, the code chunk boundaries are better kept
up-to-date, such that code[R] <-> text[LaTeX] minor mode switching
should happen more reliably.
* In noweb-mode, fix a buglet in rare [Enter] or [Tab] behavior;
further, by default disable the former '[[' .. ']]'
code-protection-when-filling behavior which has been found to be
buggy.
Changes/New Features in 5.3.9:
* ESS[SAS]: evince PDF viewer now supported as well; search order:
evince, Xpdf, Adobe/Acrobat Reader
* ESS[R]: added support for Roxygen, potentially to be extended.
* ESS[S] (and R): inferior ('*R*') and transcript modes no longer
fontify language keywords (such as 'for', 'in', etc).
* iESS[Stata]: Customize the 'ess-sta-delimiter-friendly' setting to
't' to convert embedded semi-colons to newlines for Stata
processing.
* Sweave fix for embedded blanks in PDF reader and PDF files
* Several fixes for Major Mode Convention violations in 'ess-mode'
and 'noweb-mode'.
* ESS[JAGS]: 'M-x comment-region' now available!
* ESS[S] The 'ess-swv-*' commands (and keybindings) are now in a
submenu of the "Noweb" menu, when editing Sweave files.
Changes/New Features in 5.3.8:
* ESS[JAGS]: more separation from ESS[BUGS] (as much as is currently
planned); now 'C-c C-c' on an empty '.jmd' creates a template as it
should; symbolic links are created for CODA output so BOA is happy:
from 'index.txt' to '.ind' and 'chain#.txt' to '#.out'
* ESS[SAS]: buffer-local 'ess-sas-submit-command' and
'ess-sas-submit-command-options' now recognized by
'ess-sas-submit-region'
* ESS[S]: When trying to evaluate code in an S language buffer and
there is no associated process, now start R automatically instead
of signalling an error. Also, restart R if there is an associated
process which is not running. However, do not start R just via the
"electric" '(' ('ess-r-args-auto-show').
* ESS[S]: For (one-line) functions withOUT '{ .. }' bodys, the end
of function is now correctly found more often. This notably
improves 'C-c C-c' ('ess-eval-function-or-paragraph-and-step').
* ESS[JAGS]: cleanup/re-organization of Elisp code; symbolic links
for CODA output are now only created by the new JAGS 'system'
command in version 1.0.3; specify whether this command is available
via 'ess-jags-system'; if not present, then no links are created so
that the '*shell*' buffer does not become unresponsive during the
batch run
Changes/New Features in 5.3.7:
* ESS: 'ess-default-style' now *is* customizable, i.e., changing its
value in '~/.emacs' now does have the desired effect.
* ESS: 'ess-font-lock-mode' is a new variable (default: t) which
controls whether font-locking is enabled in ESS buffers.
* ESS[R]: for XEmacs on Windows; another tweak to find R versions
* ESS[SAS]: font-locking updated for ODS and SAS Bayesian Procedures;
