Formatting

If you want to format a file on save, you have to set "editor.formatOnSave": true. See an official document.

LaTeX files

Install latexindent.pl for formatting support if it is not provided by your LaTeX distribution.

Relevant settings

latex-workshop.latexindent.path

Define the path of the latexindent executable. If latexindent is in the PATH, setting this variable to the executable name is fine.

latex-workshop.latexindent.args

Define the command line arguments for latexindent. In the addition to the placeholders defined for recipes, the following placeholders are accepted

• %TMPFILE%: The full path of the raw TeX file to be formatted. At this moment you need to use it as an input file of latexindent.

Bibtex files

There are three commands for formatting .bib files:

• latex-workshop.bibsort: to sort the file,
• latex-workshop.bibalign: to align fields,
• latex-workshop.bibalignsort: to perform both at once.

These commands can be accessed through Visual Studio Code's Command Palette (default ctrl+shift+p or ⌘+shift+p).

Sorting

latex-workshop.bibtex-format.sortby

The commands latex-workshop.bibsort and latex-workshop.bibalignsort will sort a .bib file according to an array of sorting keys specified in latex-workshop.bibtex-format.sortby. Valid keys are: any bibtex field (e.g. author, year, title) or year-desc for the year in descending order, or key for the bibtex key.

For example, set this to ["author", "year-desc", "title"] to sort by author, then year in descending order, then title
