Recipe for "on-the-fly" contexts

[sdondley]

I like to have a shell dedicated to each shell process. Project A in process A, Probject B in process B, etc.

This is presently not possible since the context is determined by the rc file.

However, there is a simple workaround:

function task() {
    command task rc.context=$FLEXIBLE_CONTEXT "$@"
}

For each shell, simply set $FLEXIBLE_CONTEXT.

But it gets better. If you have a lot of projects, you don't want the hassle of creating a separate context manually for each project. These 3 functions work together to automate things for you:

function tc() {
    FLEXIBLE_CONTEXT="$@"
    contexts=($(task _context))
    
    project=$1
    # context doesn't handle periods well for name
    project=$(tr '.' '_' <<<"$project")

    if [[ ! " ${contexts[*]} " =~ " ${project} " ]]; then
        echo "y\ny\n" | task define context $project project:$1
    fi
}

function _tc() {
    compadd "$@" $(task _projects) 
}

function tcc() {
    unset FLEXIBLE_CONTEXT
}

Just do:

tc <project_name>

This will automatically switch you over to a context filtered by project. If the project doesn't exist, a context will be crated for you with the same name as the project.

The _tc function provides tab completion for project names. This is for zsh completion. I'm not sure if it's the same for bash. Be sure to add compdef _tc tc to the .zshrc file to get it working and start a new shell process.

The tcc() function clears the context for you.
