Error while working with GoLang.

[vikaskaliramna0]

Summary

I was learning GoLang and writing some basic program. After writing some basic array, pointers and loop stuff, I tried to save the GoLang file. The editor crashed.

• No Syntax Error or any other error by LSP.
• LSP is working fine, no issues.
• Go is configured properly, hx --health go returns all options checked green.
• Never had any issue like this before with other languages.
• NOTE: Haven't tried other languages after this error with GoLang.

Files in the directory

• go.mod
• main.go

Install Location

Helix is installed in the /bin/ directory. Which I did manually are building the binary from source.

Reproduction Steps

I tried this:

1. :write

I expected this to happen:

Save the GoLang file normally.

Instead, this happened:

The editor crashed, also didn't save the GoLang file.

Could you post the log file created when this happens while running in verbose mode? (hx -v --log log.txt and then post that log.txt file. Also see https://github.com/helix-editor/helix/wiki/FAQ#access-the-log-file)

It sounds like the language server is sending an invalid edit when the end comes before the start. Fixing that is an upstream issue. The panic will be fixed by #6512 though

[vikaskaliramna0]

The log file doesn't have anything more than a single typo that I made while running :quit command.

And I am not able to re-create that error today, I don't know if it's good thing or bad thing.
I didn't update helix or golang.

I remember updating dart and an unknown package that I don't know what it was.
I reinstalled ubuntu-desktop-minimal and changed my desktop environment because of some issue with desktop.

Don't know what fixed my editor.

[vikaskaliramna0]

I am new to advanced stuff and I was try to implement bubble sort in go, wrote it so fast fluently without any mistakes and tried to saved.

Didn't save before because I forgot about this crashing, it crashed 😭

EDIT : Log file is empty :(

[the-mikedavis]

You need to run in verbose mode with the -v flag. That will raise the log level, so the log file will contain the communication between Helix and the language server

I am closing this as stale as not enough information (specifically a log file) was provided tomakw this actionable
