Paver bash auto complete

[Rohit]

Hi,
I think having a paver bash auto complete which lists all the tasks
would be extremely useful. I got the inspiration after looking at
virtualenvwrapper. I put the following code in my .bashrc:

_paver()
{
cmds=`paver -q list_tasks`
COMPREPLY=( $(compgen -W '$cmds' -- $cur))
}
complete -F _paver paver

This bash script assumes that the pavement file being used is the
default one ie pavement.py and that file has a task called
'list_tasks' which lists all the task. If 'list_tasks' task could be
merged into paver package itself, that would be really useful.

Now whenever I am in my python project directory with a pavement.py
which has the necessary 'list_tasks' method, I have auto-complete with
paver!

My two pence.

Hi Rohit,

Yes, this would be handy. I was thinking that the other day. What does list_tasks look like?

The 'list_tasks' method looks like:

@task
def list_tasks():
task_list = environment.get_tasks()
for task in task_list:
print task.shortname

I copied this bit of code from a method called 'help' in paver/
tasks.py.

Note that my script suppresses all other auto completion. So its
definitely just an idea right now.

cheers

This works without special requirements towards the pavement:

_paver()
{
    cmds=$(paver help tasks | egrep "^ .+ - " | sed -re 's/\s+(.*?)\s+-\s.*$/\1/' | grep -v ^_)

    COMPREPLY=( $(compgen -W '$cmds' -- "$cur") )
}
complete -F _paver paver

It also excludes tasks beginning with _ (i.e. "private" ones).

Paver bash autocompletion, without the need of a special "list_tasks"
task
and filtering tasks starting with _

_paver()
{
cmds=$( paver -hq | awk '/\s*([a-zA-Z][a-zA-Z0-9_]+)/
{print $1}' )

COMPREPLY=( $(compgen -W '$cmds' -- "$cur") )
}

complete -F _paver paver

i'm a couple years too late.. but this works well, as it removes the autocomplete for flag options:

_paver()

{

    local cur

    COMPREPLY=()

    # Variable to hold the current word

    cur="${COMP_WORDS[COMP_CWORD]}"

    # Build a list of the available tasks from: `paver --help --quiet`

    local cmds=$(paver -hq | awk '/^  ([a-zA-Z][a-zA-Z0-9_]+)/ {print $1}')

    # Generate possible matches and store them in the

    # array variable COMPREPLY

    COMPREPLY=($(compgen -W "${cmds}" $cur))

}

# Assign the auto-completion function for our command.

complete -F _paver paver
