Auto switching does not work with latest release of elementary OS

[AndrewVos]

Elementary comes with some setup in .bashrc which sets up it's own hooks.

I've included the part of the .bashrc where the hooks are setup, and added chruby_auto in there as a workaround.

preexec_functions is a zsh special variable and doesn't work under bash unless there's a trap DEBUG setup which emulates that behavior.

(Might want to post output of echo $SHELL)

Please paste the output of the bug_report.sh script so we can get some diagnostics.

@postmodern, thanks:

@steakknife This is not bash.

[AndrewVos]

Worth noting that there's a workaround in that gist I added ^

[bigfatbird]

I am also having problems. I need to run exec bash all the time. chruby does not even recognize I have set a value to a .ruby-version file. First I need to exec shell or manually choose the ruby version I want to use.

Works fine on my Mac, though. I also am researching what is going on and started a stackexchange thread. https://elementaryos.stackexchange.com/questions/11439/i-need-to-run-exec-bash-to-accsess-jekyll-or-ruby-for-example

@danrabbit could lend a hand maybe?

[AndrewVos]

@bigfatbird Have you tried my workaround?

[AndrewVos]

@steakknife whoops just read my comment above... I meant to say "this is not zsh".

[AndrewVos]

[~] ∞ echo $SHELL
/bin/bash

[AndrewVos]

This also works as a workaround in .bashrc

preexec_functions+=(chruby_auto)
