Strange syntax error in rbenv-version-file-read \w git-flow

[alsemyonov]

I don't know, whetther it is rbenv of git-flow problem, but when I try to run

git flow release finish 0.1.0

there is a problem, mentioning rbenv:

Switched to branch 'production'
/Users/alsemyonov/.rbenv/libexec/rbenv-version-file-read: line 16: syntax error near unexpected token `<'
Deleted branch release/0.1.0 (was 1234567).

...

And periodically it causes git-flow commands to fail.

When I try something like:

git flow feature start my-cool-feature

I get:

Switched to a new branch 'feature/my-cool-feature'
/usr/local/Cellar/rbenv/0.3.0/libexec/rbenv-version-file-read: line 16: syntax error near unexpected token `<'
Could not create feature branch 'feature/my-cool-feature'

At least in my case this is due to a post-checkout hook that calls bundle. Removing the automatic execution of bundle fixed it for the time being.

It might be that your shells don't support process substitution. It's the only occurence of process substitution used in rbenv. I just changed it to use a simple pipeline. I'll submit a pull request.

Sounds reasonable to me. Git flow uses sh under the hood.

Can you share with us your post-checkout hook that calls bundle? I'm wondering what's going on here

And sorry for not getting onto this until this late. Let's fix it if there's a bug!

[codebeige]

#!/bin/zsh

.git/hooks/ctags >/dev/null 2>&1 &

if [ $1 != 0000000000000000000000000000000000000000 ]; then
  if command -v hookup >/dev/null; then
    hookup post-checkout "$@"
  elif [ $3 = 1 -a -f Gemfile ] && command -v bundle >/dev/null &&
    git diff --name-only $1 $2 | egrep -q '^Gemfile|\.gemspec$'
  then
    (unset GIT_DIR; exec bundle) | grep -v '^Using ' | grep -v ' is complete'
    true
  fi
fi

Can't reproduce this! Very strange

[mislav]

Managed to reproduce, and filed as nvie/gitflow#289

There is no workaround apart from manually editing the git-flow executable and removing the offending line.

I'm actually running into this exact issue myself. I have one git hook in my project, and I tried removing it, but for some reason it's still choking on

/usr/local/Cellar/rbenv/0.4.0/libexec/rbenv-version-file-read: line 17: syntax error near unexpected token `<'

I generally run Zsh, but in the process of troubleshooting, I've also attempted this in bash, with the same result.

@counterbeing Can't remember if I actually got it to run back then, but I'm using https://github.com/postmodern/chruby by now. :) Works very well.

Thanks for the response! I really am fond of my current rbenv setup though, and don’t want to abandon. Thanks again!
