At some point `rvm` (for ruby) defines a `cd` shell function that are able to auto-switch to project-specific version of ruby installation whenever you `cd` into some ruby project dir, and undo so whenevere you cd out of it. I found this a great idea, but not something I wish to do for once reason -- I do projects in multilpe programming languages and if several of those tools redefine `cd`... I doubt that I could still have a workable shell in front of me. I imagine a more workable, non-intrusive, solution is something like this 1. Add `.bin` to $PATH (relative path) 2. Add `.bin/perl` that is a shim script, in which PERL5LIB, PATH, and other envs are tweaked and eventually a line of `exec perl` at the end. Having relative path in $PATH is probably as contraversial as `curl | bash` though. OTOH if it's ok not to make it looks `magic`, I don't see why we couldn't put a copy of relocatable perl under ".local/bin/perl" and have some basic, per-project shell wraper for tweaking envs. -- Kang-min LiuThread Previous | Thread Next
