Yarp autocomplete support

[traversaro]

Hi everyone,
I know that the yarp and yarp-config command line tools has autocomplete support on *nix systems, but I don't know ho to enable it. Anyone knows some relevant documentation?

Not sure if there is any documentation about... anyway:

cp $YARP_ROOT/scripts/yarp_completion /etc/bash_completion.d/yarp

Feel free to add it somewhere in the documentation :)

[traversaro]

Super cool, thanks!
Added this in Linux installation from sources tutorial, in http://wiki.icub.org/index.php?title=Linux:Installation_from_sources&diff=prev&oldid=20987 . (Perhaps should be added even in OS X one?).

@traversaro Actually

ln -s $YARP_ROOT/scripts/yarp_completion /etc/bash_completion.d/yarp

Is probably a better option, so that when the file is updated, you don't have to copy it again.

@francesco-romano does it work on OSX too?

I just checked and at the moment it does not work out of the box on cygwin, but it works if you run dos2unix on it, or if you add this before the completion script is executed (I added a file in /etc/profile.d because at the time of execution of the ~/.bashrc file is too late).

(set -o igncr) 2>/dev/null && set -o igncr;

The page http://wiki.icub.org/wiki/Generic_iCub_machine_installation_instructions suggests to add the tab completion script to your .bashrc (or similar file):

if [ -f $YARP_ROOT/scripts/yarp_completion ]; then
  source $YARP_ROOT/scripts/yarp_completion
fi

On OS X, the autocompletion does not work, as I get

bash: _get_cword: command not found

(it is in line 42)

[drdanz]

@kt10aan Is bash-completion installed? See http://www.linuxask.com/questions/install-bash-completion-for-mac-osx

[francesco-romano]

I have no problems in using auto completion on OS X

@drdanz , indeed, brew install bash-completion made it work.

Now there are two ways to continue, one is to source the $YARP_ROOT/scripts/yarp_completion in .bash_profile and the other to link the yarp_completion to brew --prefix/etc/bash_completion.d

Both work on my machine, but the first one is a bit cleaner, at least for me that I install YARP from sources.

However, it would be nice to have the YARP formula to install the yarp_completion in brew --prefix/etc/bash_completion.d (and possibly add bash-completion as dependency.

[kt10aan]

I have added the instructions for OS X in http://wiki.icub.org/wiki/Homebrew#Bash_completion.

[pattacini]

For sake of completeness on the auto-complete feature :), also Windows machines can have it enabled.

@elen4 provided some time ago a way to it along with documentation under yarp/scripts/WindowsPowerShell.

I see that in the installation from sources edit ( http://wiki.icub.org/index.php?title=Linux:Installation_from_sources&diff=prev&oldid=20987 ) the suggestion is to use the cp command. I think it would be better to add the suggestion from @drdanz of using the ln:

ln -s $YARP_ROOT/scripts/yarp_completion /etc/bash_completion.d/yarp

@fjandrad
This was changed later (http://wiki.icub.org/index.php?title=Linux:Installation_from_sources&diff=21013&oldid=20987) to @drdanz's suggestion.

However, it got then deleted and replaced with a link (http://wiki.icub.org/index.php?title=Linux:Installation_from_sources&diff=21167&oldid=21077) to http://www.yarp.it/install_yarp_linux.html. Indeed, in this page the bash auto complete is missing.

The relevant file for that tutorial is in https://github.com/robotology/yarp/blob/45e06ce13f076efce166711841ab130a04b17d4b/doc/installation/install_linux.dox , so feel free to add the tab completion instructions with a PR. @fjandrad

I think that the path changed, see https://github.com/robotology/yarp/tree/7098ab6219647603f96764cc0a7cd33a950bbfa6/data/bash-completion

Now the command would be

ln -s /full/path/to/yarp/data/bash-completion/yarp /etc/bash_completion.d/yarp

Note:

• you have to substitute /full/path/to/yarp with your full path to the yarp source directory, like /home/sdafarra/robotology-superbuild/src/yarp. Relative paths (like ./) do not work.
• most probably you need sudo
• If the file /etc/bash_completion.d/yarp already exists, you have to delete it before.

[drdanz]

Yes, but it is also installed in <prefix>/share/bash-completion/completions/yarp, which I recommend to use for the link in /etc/bash_completion.d
