Autocomplete custom scripts?
-
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-oneor./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…
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.

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

As I understand it, it works based on your bash_history which can be very small or autodeleted after each poweroff for privacy & security reasons.
So it doesn't work in that case. However, creating a file containing a list or array? Of commands could that be a possible way to implemented a similar behavior?
I'm asking because I'm not very proficient in any programming language but have done some small bash scripts here and there and quite interested in this functionality !

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 bookmarks 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.

I wonder if SikuliX may be of interest to you, then. I just invoke KeePassXC's built-in autotyper; it's not too much more painful for me. Anyway, thanks for sharing! We certainly use it for very different things.
