Subshell problems about nave HOT 13 CLOSED

You'd have to enter the subshell and THEN do the thing in there. When you exit, you're not in the subshell any more, and might not even have node (or that version of node) in your PATH any longer. That's why you're getting the node: No such file or directory error.

Does this do what you want?

./nave.sh use 0.6.5 npm install coffee-script
./nave.sh use 0.6.5 node_modules/.bin/coffee

It wouldn't be too hard to add support for passing more than just one command to the nave use statement.

It does exactly what I want! Thanks for your reply, and sorry for the non-issue.

from nave.

No problem. If you feel that the docs or API could have made this more obvious, a patch would be welcome.

from nave.

Actually, it doesn't do exactly what I want; if I do

$ ./nave.sh use 0.6.5 node_modules/.bin/coffee -cs < test.coffee | head -1

I get

already using 0.6.5

... if I'm already using it; this is a problem for my script that doesn't know whether it is already using it. Can I suppress this message? Shouldn't it go to stderr?

from nave.

Oh, yeah, that's ugly. Should be printing to stderr.

Wanna send a pull req? I think there's an echo_err function already somewhere.

from nave.

Hm, does it even need to say "already using" when the command is "use"?

from nave.

@welwood08 Well, so that's a bit tricky, actually... Should it create another nested subshell if it's already in a subshell where NAVE=0.6.5? If not, I'd like to have some kind of indication that it's not doing that.

from nave.

Ah yes, nevermind me - I was actually thinking of the "using x" message which seemed a bit verbose when that's what it was instructed to do (at one point I even had the idea to, instead of echoing node version, prefix/modify the shell prompt with it and nave level, but then the sensible, lazy me arrived). Anyway, glad it's going on stderr at least.

You mean like this? https://github.com/isaacs/dotfiles/blob/master/.extra.bashrc#L510-522

from nave.

That does indeed look like what I was thinking of but never got round to learning, thanks.

from nave.

I got a new error with the same use case; as of version 2.7, if I do

nave.sh use 0.6.5 node_modules/.bin/coffee

I get in response

Already installed: 0.6.5
using 0.6.5
/usr/bin/env: node: No such file or directory

from nave.

Aha, reproducing. Got a fix, landing now.

from nave.

Ok, fixed on 0.2.10
