As my time with linux, I created a lot of scripts. Some of them have input parameters and sometimes I just forget this parameters.

So I wonder if there is some way to create autocomplete parameters, like i autocomplete a path by pressing the tab key?

For example a script. ./test.sh can be completed with parameter-one, eg. ./test.sh parameter-one or ./test.sh parameter-two. If i type now ./test.sh followed by tab it should add parameter-one if i press tab again it should change to parameter-two.

How can I do that? I’m on bash…

    Here’s an article that does this: https://iridakos.com/programming/2018/03/01/bash-programmable-completion-tutorial

    I have done this for one of my own tools ta, which is a function that switches to a tmux session, or creates it if it doesn’t exist:

    # switch to existing tmux session, or create it.
# overrides workdir if session name is "Work"
function ta() {
        case "$1" in
                Work) workdir="${HOME}/Work/" ;;
                *) workdir="${HOME}" ;;
        esac
        if tmux has-session -t "$@" &>/dev/null; then
                tmux switch-client -t "$@"
        else
                tmux new-session -A -D -d -c "${workdir}" -s "$@"
                tmux switch-client -t "$@"
        fi
}

# complete tmux sessions
# exclude current session from completion
function _ta_completion() {
        command="${1}"
        completing="${2}"
        previous="${3}"
        [[ "${command}" != 'ta' ]] && return
        current_session="$(tmux display-message -p '#S')"
        IFS=$'\a' COMPREPLY=( $(tmux list-sessions -F '#{session_name}' | grep -i "^${completing}" | grep -v "^${current_session}$"| tr '\n' '\a' ) )
}
# enable completion for ta function
complete -F _ta_completion ta

    Usage

    $ tmux (starts session "0" by default)
$ ta Personal # create session "Personal" because it doesn't exist
$ ta Work # create session "Work" because it doesn't exist
$ ta <tab> 
0 Personal
$ ta P<tab> -> $ta Personal
$ ta <tab>
0 Work

      Espanso is probably the most useful software that nobody is using. I can’t live without it.

      I hope it gets an update soon…

        Its .YML formatting is really clunky. It feels like it takes up twice as much line space as .AHK (for example), which can do a lot of this kind of stuff in a single line. But I wanna go cross-platform and this is all I can find…

          I like YAML, as long as you aren’t using complicated syntax. Using the | operator will get you some flexible usage that’s mostly easy enough to read. YAML definitely has its problems though. If you want, I can share some snippets of my config.

          Sadly though, due to Espanso not having a working RPM build for Wayland (or a Flatpak, which they’re working on), it’s not quite as cross-platform as I want it to be. It won’t work on any of the cool uBlue-derived distros that I’ve gravitated toward, so I’m hoping we get a nice, big update this year.

            Did you put in a request for this? And sure, I’m always interested in seeing how others use it—especially to complex levels.

              It took me a while to get around to this so I could sanitize some of the highly-personal stuff there (mostly just a bunch of URLs because I don’t use browser bookmarks lol), but here’s a condensed version of what I like to use Espanso for.

              The second half is …interesting. I wanted a way to autofill passwords from my password manager in any application, not just a browser. It’s a very homebrewed solution, and it only works on Windows and Linux because macOS blocks tools like Espanso from viewing or modifying login input fields.

              Did you put in a request for this?

              For a Wayland Flatpak or RPM? I haven’t looked in a long time, but I believe there’s an open issue for a Wayland RPM.

              Edit: Found them: Flatpak issue and RPM issue.

    Not exactly what you are looking for, but modern shells like fish or zsh (probably?) are good at suggesting completions from history. fzf is another great tool for that. Both are super useful for remembering and repeating commands.
