Synthesis is a zsh script for emulating a coding style with higher order functions, lambdas and composition in the shell.
A fizzbuzz in synthesis would look like this:
fizzes=77 # however many iterations we want
⛥ seql $fizzes ⇝ partition mod 15 \
⇝ partmap 3:6:9:12 enter '«fizz»' \
⇝ partmap 5:10 enter '«buzz»' \
⇝ partmap 0 enter '«fizz buzz»' \
⇝ unify ⇝ ◎
The following code creates/updates backup files of text files belonging to the user that were accessed within the last two days:
⛥ detect '«./*.txt»' mine lastacc -2 \
⇝ map x '«cp -- $x $x.bak»'
The unicode symbols have two-keystroke keymaps for ease of input,
as well as suggested non-unicode replacements. For instance, ⛥ is
inserted with `q (backtick-q) and the pipe arrow ⇝ with `p.
The script was created for my personal use, inspired by previous efforts to provide functional templates in the shell, and then expanded into a more generic tool over the course of the last few months. It is an amateur project so please be very careful if you decide to use it.
For more information, credits, caveats etc, check the documentation
in documentation.md. Both the script and the documentation are
works in progress.
Clone this repository locally and source the file synthesis.zsh. Note
that the file contains escape sequences for some of the keybindings
in order to reposition the cursor; looking at the raw file from
the browser, these sequences are stripped off. If the keybindings
`1 and `2 do not properly position the cursor in the
center of the brackets, you need to supply these keystrokes at the
bindkeys near the end of the file.
The documentation has more information on the prerequisites and first steps into this environment.
