Commands and Extensions

[mocenigo]

Hello, how do i create commands in the settings.json file, for instance, to call a specific external tool?
I guess that then adding a keybinding would be easy.
But, is there already a mechanism to do all of this into an extension? (The same question was asked in #17226)
It would be nice to have a tutorial with one example.

On a related note, hoow can one add snippets into an extension, and add visual clues to the editor on how to make the corresponding snippets panel appear in a dock? This could also go into that tutorial

You can use tasks to run commands using the integrated terminal. See https://zed.dev/docs/tasks

Solved for Skim

I disable forwardSearch on save, and define the following command

[
  {
    "label": "Forward Search",
    "command": "str=$(grep -e \"%.*TEX root = \" -m 1 -n $ZED_FILE); if [ \"$str\" = \"\" ]; then str=$ZED_STEM; else str=$(echo $str | sed \"s/[0-9]*:%.*TEX root = \\(.*\\).tex/\\1/\"); fi; echo $str; /Applications/Skim.app/Contents/SharedSupport/displayline -r -b $ZED_ROW $ZED_DIRNAME/$str.pdf $ZED_FILE",
    "allow_concurrent_runs": false,
    "reveal": "never ",
    "hide": "always",
  },
]

It sucks that JSON does not allow line split literals.

Note that this allows a file to be opened and previewed from an included one if the included file contains a line like
% TeX root = main-file-name.tex
or
% !TeX root = main-file-name.tex
(with or without a space after the %).

The Skim displaylike allows to give also a tex file name as the parameter AFTER the pdf file and this version allows to jump also to the right place FROM an included file, as long as there is a commented line containint
"TEX root = " followed by the file name (also, respect the spaces between these words and after the "=", as in TeXshop and similar programs.

I guess this should be included in the latex-lsp extension with an option to install the Skim.app command.
