Applying snippets (in different languages) to dired or buffer files

https://xenodium.com/emacs-dwim-shell-command-multi-language/ Another usage of `dwim-shell-command-on-marked-files`, this time in non-shell languages. Python (defun dwim-shell-command-csv-to-json-via-python () "Convert csv file to json (via Python)." (interactive) (dwim-shell-command-on-marked-files "Convert csv file to json (via Python)."

Interesting! I think it should be possible to do this in lisp as well...

You mean solve csv to json in elisp? Or integrating some other lisp (Common Lisp?) like shown for python and swift? Either way, yes ;)

Yeah the former.

Ah yeah. The csv -> json conversion was more of a sample problem. We can solve it in elisp (and I typically do), but sometimes it's quicker to just use an existing snippet one already has in a different language. Multi-language brings convenience when you also inherit the other DWIM support from \`dwim-shell-command-on-marked-files\`.

Also thanks for the accidental demo of `TabularData`. Didn't look into the new API just yet :)

👍 that was my first time using the tabular data Swift API, and didn’t quite use it other than a constant :)

A little off-topic, but what font is that?
