Add documentation on adding the runtime variable for specific languages (go, Typescript, Rust) about helix HOT 10 CLOSED

I now get highlighting and goto definition and stuffz !!

Ah, so you mean

Now copy the runtime/ directory somewhere. Helix will by default look for the runtime inside the same folder as the executable, but that can be overriden via the HELIX_RUNTIME environment variable.

I was confused about that either. No wonder I didn't get syntax highlighting. Oh, I found it. Have to set HELIX_RUNTIME=$PWD. Maybe we should update the docs.

Runtime variable?

An example from my personal configuration.

/tmp $ which hx
/Users/kevinsjoberg/bin/hx

/tmp $ ls -l $HOME/.config/helix/
total 8
-rw-r--r--  1 kevinsjoberg  staff  1560 Jun  2 22:09 helix.log
drwxr-xr-x@ 3 kevinsjoberg  staff    96 Jun  3 04:07 runtime

/tmp $ echo $HELIX_RUNTIME
/Users/kevinsjoberg/.config/helix/runtime

@pickfire I believe hx will look for the runtime folder in the same directory as the binary by the default. This can be changed by setting the HELIX_RUNTIME environment variable to a different directory.

@kevinsjoberg thx for the clear example.
I downloaded the release, but did not know where to put the things. 👯

Yea I was thinking to update the docs, with this explicit information.
So that It gets easy to open hx and start to play around and making it more frictionless.

The binary looks for runtime/ where the executable is located, or for a HELIX_RUNTIME override.

If running this in development via cargo run I recommend using an .envrc file to automatically set the var. We could also try detecting that (if debug mode) and setting it to the correct path.

For packaged installs, I recommend unpacking the files somewhere, then making a hx wrapper that sets the var and runs the binary. Example from Arch Linux

I agree with the package install that sets the VAR to some default where the default runtime is set on all comp.

@archseer
For releases or anything in the documentation, we could add commands that would make it easier to add the ENV to point to a ~/.config/helix by default if not specified.

Maybe this is what you mean by the package installs. But would be great to get this in right away.

Package installer for me did not work:
I did not get it to install for my Ubuntu 20.04 distro though. Maybe this is just me

I don't think it correctly detects it on Windows without the envvar.

I think this should be solved in 0.2.0, we have more reasonable defaults now.
