When I run a rake command related to Octopress (using Jekyll) to create a new blog post, I type:
rake new_post["Post title"]

This normally works great; however once I enabled bundler-exec, I received the error:
rake aborted!
Don't know how to build task 'new_post[Post'

I confess to not being sure exactly where the problem is; but it would seem somewhere along the lines the quotes are being interpreted, and lost, and not passed on, and so then the spaces become a problem.

The list of files being included in bundler-exec is getting pretty thick, and creating issues and pull requests to add new ones gets tedious.

Could we use a really simple list (rails, rake, ...) and something like .bundler-execrc or the like to list out the extra commands which should be run using bundler?

once in a while i do not want to use bundler -> it should be possible to circumvent this

e.g. NO_BUNDLER=1 ruby -e 'test'

After installing bundle-exec, rake no longer works (see bottom of stacktrace)

Your package bundler-exec (version latest-1) provides a fault script /etc/profile.d/bundler-exec.sh because of which I was not able to login to GNOME 3.20 on Arch Linux. More details: https://bbs.archlinux.org/viewtopic.php?id=211284
You must know that all the scripts in /etc/profile.d directory are run by sh at the time of login in GDM (usually because bash or zsh are default shell). sh shell does not allow - in the name of identifiers, so I get this error

Apr 13 14:36:59 ArchLinux /usr/lib/gdm/gdm-x-session[2719]: /etc/profile.d/bundler-exec.sh: line 12: `bundler-installed': not a valid identifier

you should please fix this problem asap :-) I have installed this package from https://aur.archlinux.org/packages/bundler-exec/
Fixing it requires to remove - from all identifiers

Just an idea:
instead of manually adding every ruby executable, how about having 'any ruby executable' as default.
Im not really sure if its possile, but it would be nice <-> would prevent these 'I added rspec/turn/xxx' pull requests :)

Whenever I run a supported command within a bundler directory.

The current version of run-with-bundler:

run-with-bundler()
{
    if bundler-installed && within-bundled-project; then
        if [ $command == "ruby" ]; then
            ruby -rbundler/setup "$@"
        else
            bundle exec $command "$@"
        fi
    else
        "$@"
    fi
}

Through some echo statements I discovered that $command is not set, and $@ is the entire command entered. So I changed it to use $1, thus:

run-with-bundler()
{
    if bundler-installed && within-bundled-project; then
        if [ $1 == "ruby" ]; then
            ruby -rbundler/setup "$@"
        else
            bundle exec "$@"
        fi
    else
        "$@"
    fi
}

Now it works.

First off, I'm new to bash, ruby, and rails, so my knowledge on bash is a little limited

Sourcing .bundler-exec.sh from .bashrc doesn't seem to be working for me.

I get these errors:

-sh: 'bundler-installed': not a valid identifier -sh: 'within-bundled-project': not a valid identifier -sh: 'run-with-bundler': not a valid identifier

My .bashrc, .profile, and .bash_profile are all symlinks to files in my dropbox folder. I wonder if that could have anything to do with it. I know my .bashrc files is loading everything else properly except for [ -f ~/.bundler-exec.sh ] && source ~/.bundler-exec.sh.

Any suggestions?
