"[Error] `tl types` has returned an empty response" whenever I open a tl file

[horatiohafnaugels]

Whenever I open or save a tl file with VS Code I get this error: [Error] tl types has returned an empty response

I'm using the latest precompiled binary version of tl (0.11.2+dev) on Windows 10 and the latest version of vscode-teal available on the marketplace (v0.7.4).

Thanks for the bug report. On the command line, can you try running tl types <filename> on one of the files that are causing the error? You should see a JSON response.

Now that I think of it, the extension might have some trouble picking up the tl executable because it assumes tl is a .bat script, not an .exe: https://github.com/teal-language/vscode-teal/pull/11

tl types <filename> invoked from the command line works as expected, producing the JSON response.

The issue should be fixed on latest master. I will push the fix to the marketplace as soon as tl gets a new release.

@horatiohafnaugels @evanpaul22 I pushed a new release, does it work now?

@pdesaulniers That error went away for me!

I have a new (likely unrelated) error "[Error] Could not find the tl executable Please make sure that is available in the PATH"

This definitely seems like a me problem though; I actually have luarocks and tl installed on my Ubuntu WSL. Probably the answer would be to install them both outside of WSL and add tl to the PATH like mentioned

[pdesaulniers]

@evanpaul22 Yeah, on Windows, the extension tries to invoke tl using the default shell (generally cmd.exe).

As a workaround, you could probably create a shell script called tl.bat to serve as a bridge between cmd.exe and WSL. Something like this (disclaimer: I didn't test it!)

@echo off
wsl.exe tl %*

Then, just make sure the script is available in the PATH outside of WSL, so that the extension can detect it.

Clever! I'll give it a try. Thanks!

@evanpaul22 On second thoughts, you might run into some issues, considering that Windows-style paths differ from POSIX-style paths:

# POSIX
/somedir/myfile

# Win32
C:\\somedir\\myfile

tl inside WSL might not be able to understand Windows-style paths. (Also, I don't know how require() would behave with this setup :))

Anyway, I'm closing this issue in favor of https://github.com/teal-language/vscode-teal/issues/35.

Yes, it does. Thank you a lot!
