Format

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.

type	default value
string	"latexindent"

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.
• %INDENT%: The indent character of the file, typically \t, ' ', ' '.

Note: For the moment the -c option requires trailing slash."

type	default value
Array of strings	[ "-c", "%DIR%/", "%TMPFILE%", "-y=defaultIndent: '%INDENT%'" ]

Bibtex files

BibTeX files can be formatted either by using the VSCode Format Document or Format Selection commands or by calling one of the following three commands

• 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).

Whether to sort the file when calling VSCode formatting commands is set by latex-workshop.bibtex-format.sort.enabled. When formatting bibtex entries, you can decide to keep the trailing comma of the last field in each entry by setting latex-workshop.bibtex-format.trailingComma to true

Sorting entries

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 either a bibtex field name (title, author, year, etc.), or \"year-desc\" to sort by year in descending order, or \"key\" for the entry key, or \"type\" for the entry type (article, book, misc, etc.). E.g. [\"author\", \"year-desc\", \"title\"].". For example, set this to ["author", "year-desc", "title"] to sort by author, then year in descending order, then title

Type	Default Value
array of strings	[ "key" ]

latex-workshop.bibtex-format.handleDuplicates

When sorting BibTeX files, how to handle duplicates that appear. Duplicates are decided by latex-workshop.bibtex-format.sortby.

Type	Default Value	Possible Values
enum of string	"Highlight Duplicates"	"Ignore Duplicates", "Highlight Duplicates", "Comment Duplicates"

latex-workshop.bibtex-format.sort.enabled

Sort content when calling VSCode formatter on a .bib file.

Type	Default Value
boolean	false

latex-workshop.bibtex-entries.first

When latex-workshop.bibtex-fields.sort.enabled is true, these fields are put at the top, in the order defined by the array.

Type	Default Value
array of strings	[ "xdata", "string" ]

Aligning fields

The commands latex-workshop.bibalign and latex-workshop.bibalignsort provide basic alignment of bibliography entries. This action can be configured through the following options.

latex-workshop.bibtex-format.tab

What kind of indentation to use before each field.

Type	Default Value
string	"2 spaces"

The possible values are: "tab", "X spaces" or simply "X" where X is a number.

latex-workshop.bibtex-format.align-equal.enabled

Align equal signs inside each entry.

Type	Default Value
boolean	true

latex-workshop.bibtex-format.surround

Whether to surround each field value in quotation marks or curly braces.

Type	Default Value	Possible Values
enum of string	"Curly braces"	"Curly braces", "Quotation marks"

latex-workshop.bibtex-format.case

Whether to use upper- or lowercase field names. (E.g. AUTHOR = ... vs author = ...).

Type	Default Value	Possible Values
enum of string	"lowercase"	"UPPERCASE", "lowercase"

latex-workshop.bibtex-format.trailingComma

Keep the trailing comma of the last field item.

Type	Default Value
boolean	false

Sorting fields

latex-workshop.bibtex-fields.sort.enabled

Sort fields inside every entry. The sorting order is defined by latex-workshop.bibtex-fields.order. This variable only has effect when formatting bibtex aligns fields. It is not possible to sort entries without aligning them.

Type	Default Value
boolean	false

latex-workshop.bibtex-fields.order

When latex-workshop.bibtex-fields.sort.enabled is true, sort fields according the order defined here and then alphabetically for not listed fields."

Type	Default Value
array of strings	[ ]
