Re: [Modules] How to use set-function?

[Xavier D. <xav...@gm...>]

Hello Pierre,

The 'function-string' parameter of the set-function modulefile command
expects the function definition in the targeted shell language. If you
target sh shells, the conda function you describe could be set-up by the
following modulefile content:

#%Module
set-function conda {
    if [ "$#" -lt 1 ]; then
        $_CONDA_EXE
    else
        \local cmd="$1"
        shift
        case "$cmd" in
            activate)
                _conda_activate "$@"
                ;;
            deactivate)
                _conda_deactivate "$@"
                ;;
            install|update|uninstall|remove)
                $_CONDA_EXE "$cmd" "$@" && _conda_reactivate
                ;;
            *)
                $_CONDA_EXE "$cmd" "$@"
                ;;
        esac
    fi}

If you target multiple shells, you should define the function content for
each of them:

#%Module
# define function content depending on current shell family
switch -- [module-info shelltype] {
    {sh} {
        set condafunc {... sh function definition ...}
    }
    {fish} {
        set condafunc {... fish function definition ...}
    }
}
# define function if current shell supports shell function
if {[info exists condafunc]} {
    set-function conda $condafunc
}

Cheers,
Xavier
