INTRODUCTION *vimtex-introduction*
VimTeX provides convenient functionality for editing LaTeX documents. The
main goal of VimTeX is to be simple, functional, and to be easy to customize
and evolve.
The documentation is understandably too long for a full read through. It is
recommended that new users read or skim the entire introduction, as it should
give a clear idea of what VimTeX is and is not. The remaining part of the
documentation should then be considered a reference for the various parts of
the plugin.
------------------------------------------------------------------------------
COMMENT ON INTERNAL TEX PLUGIN *vimtex-comment-internal*
Vim ships with pretty decent LaTeX support out of the box. In particular, it
provides syntax highlighting (|ft-tex-syntax|), indentation (see the source
file $VIMRUNTIME/indent/tex.vim for the documentation), and some sensible
options (|ft-tex-plugin|).
*vimtex-tex-flavor*
When VimTeX is active, it will override the internal TeX plugin for the
filetype `tex` (|ft-tex-plugin|), both for syntax highlighting and for
filetype specific features. To prevent the unexpected behaviour where `.tex`
files by default will be recognized as the filetype `plaintex`
(|ft-plaintex-syntax|) for e.g. empty documents, VimTeX overrides the filetype
detection for `.tex`. The user may prevent this overriding by specifying the
|g:tex_flavor| option something different than `'latex'`.
-----------------------------------------------------------------------------

REQUIREMENTS *vimtex-requirements*
The following is a list of specific requirements for running VimTeX and some
of its key features. Windows users should also read |vimtex-faq-windows|, and
neovim users should read |vimtex-faq-neovim|.
Vim version~
*vimtex_version_check*
VimTeX requires Vim version 8.0.1453 or neovim version 0.4.3. It will not
load for older versions, unless one adds >
let g:vimtex_version_check = 0
<
to one's `vimrc` file. This might work, but issues due to older versions
than the mentioned here will be ignored.
Vim configuration~
VimTeX requires |:filetype-plugin-on| and optionally |:filetype-indent-on|.
There are several features in VimTeX that depend on the syntax parsing used
for syntax highlighting. Examples include functions like
|vimtex#syntax#in_mathzone| and text objects like |<plug>(vimtex-i$)|. This
is important to be aware of especially for neovim users who are interested
in Tree-sitter. If you use Tree-sitter for syntax highlighting and thus
disable the normal Vim syntax feature, then you will also loose the VimTeX
features that depend on the built-in syntax parser.
Some of the VimTeX scripts contain UTF-8 characters, and as such, it is
necessary to have the 'encoding' option set to utf8. This is not necessary
in neovim, only in Vim. Add the following to your vimrc file: >
set encoding=utf8
Compiler backend~
VimTeX uses `latexmk`, `latexrun`, `tectonic` or `arara` to compile the LaTeX document.
`latexmk`: http://users.phys.psu.edu/~collins/software/latexmk-jcc
"a perl script for running LaTeX the correct number of times to resolve
cross references, etc; it also runs auxiliary programs (bibtex, makeindex if
necessary, and dvips and/or a previewer as requested). It has a number of
other useful capabilities, for example to start a previewer and then run
latex whenever the source files are updated, so that the previewer gives an
up-to-date view of the document. The script runs on both UNIX and MS-WINDOWS
(XP, etc)." [Copied from the latexmk page.] (|vimtex-compiler-latexmk|)
`latexrun`: https://github.com/aclements/latexrun
Similar to `latexmk` in that it runs the desired LaTeX engine an
appropriate number of times, including `bibtex`/`biber`. However, it differs
in philosophy in that it only does the build part. It does not support
continuous builds, nor automatic starting of the viewer. However, it does
parse the output log in order to provide a more concise list of relevant
warnings and error messages (this has currently not been adapted to VimTeX,
as of yet). (|vimtex-compiler-latexrun|)
`tectonic`: https://tectonic-typesetting.github.io/
`tectonic` is a complete, self-contained TeX/LaTeX engine, powered by XeTeX
and TeXLive. It doesn't support continuous build like `latexmk` but it
presents other worth mentioning features such as automatic support file
downloading along with reproducible builds and full Unicode and OpenType
fonts support thanks to the power of XeTeX. (|vimtex-compiler-tectonic|)
`arara`: https://github.com/cereda/arara
`arara` is a TeX automation tool similar to the above mentioned tools,
but where the compilation behaviour is typically defined in the preamble
of the document. (|vimtex-compiler-arara|)
Clientserver~
*vimtex-clientserver*
Vim requires |+clientserver| in order to allow inverse search from the PDF
viewer to Vim (see |vimtex-synctex-inverse-search|). The clientserver is
used by VimTeX. Thus, if one uses Vim one must ensure that it starts
a server. Neovim does not have this requirement.
A server will be started automatically if Vim is running on Windows or if it
is running in a GUI (gVim). If you use Vim under a terminal in Linux or
MacOS, a server will not be started by default. Since Vim version 8.0.475,
one can use |remote_startserver()| to start a server from your `vimrc` file.
The following vimrc configuration snippet will ensure that Vim starts with
a server, if possible: >
if empty(v:servername) && exists('*remote_startserver')
call remote_startserver('VIM')
endif
<
Alternatively, Vim can be started with the command line option
`--servername`, e.g. `vim --servername VIM` . The simplest way to ensure
this is to add an alias to your `.bashrc` (or similar), that is, add: >
alias vim='vim --servername VIM'
<
One can use |serverlist()| to check whether a server was successfully
started, e.g. with `:echo serverlist()`.
Neovim does not implement the same clientserver feature. Instead, it
implements the MessagePack-RPC protocol (see |RPC|). VimTeX relies on this
protocol in the same fashion as the clientserver. Both Vim and neovim have
the |v:servername| variable that contains the name/location of the server
with which we need to communicate.
------------------------------------------------------------------------------
SUPPORT FOR MULTI-FILE PROJECTS *vimtex-multi-file*
VimTeX supports most multi-file documents. The main method uses a recursive
search algorithm that should find the main LaTeX file in most cases. For
special cases, there are several alternative methods for specifying the main
file. These alternative methods all require some explicit declaration of the
main file. Thus, these methods will be tried first, and the recursive search
is tried last if there are no explicit declarations that yield an appropriate
main LaTeX file candidate.
The methods are tried in the following order:
1. Buffer variable
2. TeX root directive
3. Subfiles package
4. File `.latexmain` specifier
5. Local `latexmkrc` file specifier (from `@default_files` option)
6. Recursive search
*b:vimtex_main*
Buffer variable~
The main file may be specified through the buffer variable `b:vimtex_main`.
To take effect, it has to be set prior to loading the buffer. If set after
the buffer is already loaded, |:VimtexReloadState| (by default bound to
|<localleader>lX|) can be used to make VimTeX aware of its new value.
A convenient way to use this feature is to add an |BufReadPre| |autocmd| in
ones |vimrc|. An example is warranted: >
augroup VimTeX
autocmd!
autocmd BufReadPre /path/to/project/*.tex
\ let b:vimtex_main = '/path/to/project/main.tex'
augroup END
<
Note: When writing such rules, one should be aware that the `*` is not the
same as regular globbing because it also includes directory
separators. Also, one should use `/` on every OS. See |file-pattern|
for more info on the |autocmd| file pattern syntax.
Note: Users may be interested in the concept of project specific vim
configuration. This is supported in Vim and neovim already, see 'exrc'
and 'secure'. There are also several plugins to help work with project
specific settings, such as:
* https://github.com/embear/vim-localvimrc
* https://github.com/tpope/vim-projectionist
*vimtex-tex-root*
TeX root directive~
It is also possible to specify the main TeX file with a comment in one of
the first five lines of the current file. This is often referred to as a TeX
directive, see |vimtex-tex-directives| for more info. The syntax is best
described by some examples: >
%! TEX root = /path/to/my-main.tex
% ! TeX root = ../*.tex
%!Tex Root=**/main.tex
<
As can be seen, the words "tex root" are recognized regardless of casing and
the spaces are ignored.
Note: It is allowed to use a globbing pattern (see |wildcards|). If there
are multiple matches, then VimTeX will ask for input when the buffer
is opened.
*vimtex-subfiles*
*vimtex-import*
Subfiles package~
VimTeX also supports the `import` [0] and the `subfiles` [1] packages that
can be used to make it easier to work with multi-file projects. If one uses
the `subfiles` package, the |:VimtexToggleMain| command is particularly
useful. Also note the option |g:vimtex_subfile_start_local|, which can be
used to automatically start in the local mode when opening a subfile
document.
With `subfiles`, included files will typically look like this: >
\documentclass[<main-path>]{subfiles}
\begin{document}
...
\end{document}
<
Here `<main-path>` is the path to the main file. It must be specified as
relative to the particular subfile. So, given the structure: >
main.tex
sub/sub.tex
<
The header in `sub.tex` should be `\documentclass[../main.tex]{subfiles}`.
Absolute paths like `/home/user/main.tex` are also allowed and should work
as expected.
[0]: https://www.ctan.org/pkg/import
[1]: https://www.ctan.org/pkg/subfiles
File .latexmain specifier~
In some cases, it might be preferable to specify the main file by creating
an indicator file. The indicator file should be an empty file, and the name
must be the name of the desired main file with `.latexmain` appended. An
example should make this clear: >
path/file.tex
path/file.tex.latexmain
path/sections/file1.tex
path/sections/file2.tex
<
Here `path/file.tex.latexmain` indicates for `file1.tex` and `file2.tex`
that `path/file.tex` is the main LaTeX file.
Local latexmkrc file specifier~
It is possible to specify to latexmk which files to compile with the
`@default_files` option in the `latexmkrc` configuration file. VimTeX
supports reading this option in any LOCAL `latexmkrc` or `.latexmkrc` file.
Note: `@default_files` is a list of files, VimTeX will use the first
entry that is found.
Recursive search~
If no other method provides an appropriate candidate, then the recursive
search detects the main LaTeX file by searching for a file in the current
and parent directories that includes the present file and has the
`\documentclass` line.
This should work in most cases, but it may fail if for instance the project
structure is something like this: >
path1/main.tex
path2/chapter.tex
<
That is, the main file detection will not work for the file `chapter.tex`,
because the main file does not live in the same folder or a parent folder.
In this particular case, the TeX root directive should work.
Note: In rare cases, such as if there are _very_ many tex files in the
directory tree, this method may be slow. One may therefore disable it
through the option |g:vimtex_disable_recursive_main_file_detection|.
------------------------------------------------------------------------------
SUPPORT FOR TEX DIRECTIVES *vimtex-tex-directives*
VimTeX supports two of the commonly used TeX directives [0]: the TeX root and
the TeX program directive. The TeX root directive was already described above,
see |vimtex-tex-root|.
*vimtex-tex-program*
The TeX program directive works by specifying the TeX compiler program in
a comment in one of the first lines of the main project file. It is parsed
only when it is required by a compiler backend.
The syntax is best explained with an example: >
%! TeX program = lualatex
%! TEX TS-program = xelatex
The left-hand side must contain the text "tex program" or "tex ts-program" and
as for |vimtex-tex-root|, the words are recognized regardless of casing and
the spaces are ignored. The right-hand side must correspond to a key in the
|g:vimtex_compiler_latexmk_engines| or |g:vimtex_compiler_latexrun_engines|
dictionaries. See also [0,1].

[1]: https://github.com/lervag/vimtex/issues/713
------------------------------------------------------------------------------
PACKAGE DETECTION *vimtex-package-detection*
VimTeX maintains a list of latex packages that are required by the current
project. This list is used by VimTeX for instance to determine which commands
to suggest during command completion (see |vimtex-complete-commands|) and
which packages to look up documentation for (see |vimtex-doc-package|). The
list can be viewed with |:VimtexInfo|.
The package list is determined in two ways: >
1. If a `.fls` file exists having the name of the main file, it is scanned.
This file is created by `latex` (or `pdflatex`, `xelatex`, ...) if it is
run with the `-recorder` option (which is set by default when using
latexmk, unless overridden in an initialization file). Parsing the `.fls`
file is done both at VimTeX initialization and after each successful
compilation, if possible.
Note: Parsing after successful compilations requires that one uses
a) continuous compilation with callbacks (see the `callback` option
for |g:vimtex_compiler_latexmk|), or
b) single-shot compilation.
2. Otherwise, the preamble is parsed for `\usepackage` statements. This is
slower and less accurate than `.fls` file parsing. Therefore, it is only
done during VimTeX initialization. If desired, one may manually reload
VimTeX to parse the preamble again during an editing session. See
|:VimtexReload| and |<plug>(vimtex-reload)| (by default mapped to
`<localleader>lx`).
------------------------------------------------------------------------------
INTEGRATION WITH OTHER PLUGINS *vimtex-and-friends*
VimTeX provides a lot of convenient and useful features for working with LaTeX
files. However, there are several features that one might expect to be part of
VimTeX, but that are left out because they are better served by other plugins.
Let's call them "friends".
The following is an overview of some such features. We also try to give hints
and suggestions for how to best integrate with VimTeX experience, if that is
applicable.
* Linting and syntax checking |vimtex-af-linting|
* Snippets/Templates |vimtex-af-snippets|
* Tag navigation |vimtex-af-tag-nav|
* Manipulate surrounding cmds/delims/envs |vimtex-af-surround|
* Enhanced matching and highlighting of delimiters |vimtex-af-enhanced-matchparen|
* Formatting |vimtex-af-formatting|
* Filetype plugin for bib files |vimtex-af-ftplugin-bib|
* Language servers (texlab & ltex) |vimtex-af-lsp|
Linting and syntax checking~
*vimtex-af-linting*
VimTeX has some support for linting through the |:compiler| command, see
|vimtex-lint|. There exists several more dedicated, automatic linting
plugins. The following plugins have support for (La)TeX syntax checking
through `lacheck` [0], `chktex` [1], and `proselint` [2].
`ale` https://github.com/dense-analysis/ale
`neomake` https://github.com/neomake/neomake
`syntastic` https://github.com/vim-syntastic/syntastic
`neomake` also supports `rubberinfo` [3]. One may also be interested in
`blacktex` [4], which may be used to clean up/fix LaTeX code.

[2]: http://proselint.com/
[3]: https://www.systutorials.com/docs/linux/man/1-rubber-info/
[4]: https://github.com/nschloe/blacktex
Snippets/Templates~
*vimtex-af-snippets*
Snippets and/or templates are provided by for instance `neosnippet` and
`UltiSnips`. See |vimtex-neosnippet| and |vimtex-UltiSnips| for more info.
Tag navigation~
*vimtex-af-tag-nav*
One may navigate by tags with the |CTRL-]| mapping, e.g. from
`\eqref{eq:example}` to the corresponding `\label{eq:example}`. However,
this requires that a tag file has been generated with |ctags|. I recommend
that one uses the maintained version of ctags [0]. In addition,
I recommend that one uses a plugin that automatically generates the tag
files as necessary, e.g. |gutentags| [1].
See |vimtex-faq-tags| and |vimtex-faq-tags-bibtex| for concrete examples.
[0]: https://ctags.io/
[1]: https://github.com/ludovicchabant/vim-gutentags
Manipulate surrounding commands/delimiters/environments~
*vimtex-af-surround*
VimTeX provides mappings that change, delete and toggle commands,
delimiters and environments (see the `ds`, `cs` and `ts` family of
mappings listed under |vimtex-default-mappings|). These mappings are
inspired by the great `surround.vim` [0] (|surround.txt|) by Tim Pope,
which provides mappings to manipulate surrounding delimiters such as `''`,
`""`, `()`, `[]`, `{}`, and `<>`. As such, the mappings from VimTeX
should work well together with, and as an extension of, `surround.vim`.
Consider also the customization described under |vimtex-faq-surround|.
The mappings may be repeated with the dot (|.|) command. See also
|g:vimtex_delim_list| if you are interested in customizing the delimiter
pairs that are recognized.
A different possibility is to use `vim-sandwich` [1] (|sandwich.txt|) by
Machakann, which may be considered a generalisation of `surround.vim` in
that it can handle much more complex sets of delimiters. `vim-sandwich`
is relatively easy to expand with custom surroundings and has built in
support for LaTeX-specific surroundings such as quotations, ```text''`,
and math delimiters, `$\left(a+b\right)$`. For a list of supported
delimiters, see |sandwich-filetype-recipes|. `vim-sandwich` supports
`vim-repeat` [2] in addition to `visualrepeat.vim` [3].
Note: The default mappings of `vim-sandwich` differ from those of
`surround.vim`, in that they use `s` as the prefix. E.g., to add
surroundings, one uses `sa{motion/textobject}{type-of-surrounding}`
instead of `ys{motion/textobject}{type-of-surrounding}`. If one prefers
the map variants from `surround.vim`, these are also available as an
option, see |sandwich-miscellaneous|. And it is also easy to define
custom mappings, if one prefers that.
Note: `vim-sandwich` actually consists of three plugins that work
together. One should make sure to read the docs for all of them:
|sandwich.txt|, |operator-sandwich.txt|, and |textobj-sandwich.txt|.

[1]: https://github.com/machakann/vim-sandwich
[2]: https://github.com/tpope/vim-repeat
[3]: http://www.vim.org/scripts/script.php?script_id=3848
Enhanced matching and highlighting of delimiters~
*vimtex-af-enhanced-matchparen*
VimTeX highlights and allows navigation between matching pairs of
delimiters including those in math mode, such as `\bigl(` and `\bigr)`, and
the `\begin` and `\end` tags of environments. However, the implementation
may be slow (see also |vimtex-faq-slow-matchparen|, and so one may use
|g:vimtex_matchparen_enabled| to disable the highlighting).
Alternatively, one may use the plugin |match-up| [0], which offers enhanced
|matchparen| highlighting and `matchit.zip` style motions and |text-objects|
for a variety of file types. For LaTeX documents, it:
- Extends highlighting and the `%` motion to a number of middle
delimiters including
- `\bigm` and `\middle` marked delimiters
- `\item`s in `itemize` and `enumerate` environments
- `\toprule`, `\midrule`, `\bottomrule` in the `tabular` environment.
- `\if`, `\else` and `\endif`
Note: VimTeX does not support highlighting the middle delimiters.
- Adds motions, `g%`, `[%`, and `]%` and text objects, `a%` and `i%` which move
between matching delimiters and operate on delimited text.
For example, with match-up enabled, >
\left( \frac{a}{b} \middle| q \right)
<
the motion `%` will cycle through `\left(`, `\middle|`, and `\right)`, whereas
with VimTeX only `\left(` and `\right)` will be matched. The motion `g%`
will do the same, except in reverse.
To enable the plugin match-up after installation, add the following to
your vimrc: >
let g:matchup_override_vimtex = 1
<
Matching may become computationally intensive for complex LaTeX documents.
If you experience slowdowns while moving the cursor, the following option
is recommended to delay highlighting slightly while navigating: >
let g:matchup_matchparen_deferred = 1
<
Note: The exact set of delimiters recognized may differ between match-up
and VimTeX. For example, the mappings `da%` and `dad` will not in general
be identical, particularly if you have customized VimTeX's delimiters.
[0]: https://github.com/andymass/vim-matchup
Formatting~
*vimtex-af-formatting*
VimTeX has a custom |formatexpr| that may be enabled with the option
|g:vimtex_format_enabled|. However, there are a lot of different styles for
formatting LaTeX manuscripts. These are typically much more relevant when
writing in collaboration with others. A good reference on this topic is [0],
and note in particular the box "Directives for using LaTeX with version
control systems".
The most basic style is to hard wrap lines at a given column, e.g. 80
columns, and this is exactly the type of formatting that is supported by
VimTeX. However, this is usually not very friendly when collaborating with
others, as it tends to mess up diffs between versions of the document.
Instead, one might want to consider one of these:
a) keeping each sentence on a line (use soft wrapping)
b) add additional indentation for split sentences [1]
c) use semantic line feeds [2]
In order to make it easier to use one of these styles of formatting, one may
want to use an external formatter:
- latexindent.pl [3]
- vim-bucky [4] (note: this is an alpha version as of October 2018)
Further, there are a range of Vim plugins that can be used to format your
document with external tools. Some of these also allow autoformatting of
some kind. In no particular order:
- neoformat [5]
- vim-codefmt [6]
- vim-autoformat [7]
- ale [8]
- vim-sentence-chopper [9]

Filetype plugin for bib files~
*vimtex-af-ftplugin-bib*
VimTeX is not a full filetype plugin for bibliography (`.bib`) files. However,
it does alter the 'comments' and 'commentstring' options and provide basic
indentation and folding; see |g:vimtex_indent_bib_enabled| and
|g:vimtex_fold_bib_enabled|, respectively.
Here are a couple of other related Vim plugins and external tools that might
be of interest:
- `bibtool`
An external tool for formatting, sorting, filtering, merging, and more of
`.bib` files.
http://www.gerd-neugebauer.de/software/TeX/BibTool/
- `GooseBib`
Some simple command-line tools to clean-up / modify BibTeX files.
https://github.com/tdegeus/GooseBib
- `tbibtools`
A set of ruby-based bibtex-related utilities for sorting, reformatting,
listing contents, and so on. Has optional Vim integration.
https://www.vim.org/scripts/script.php?script_id=1915
See also https://github.com/lervag/vimtex/issues/1293 for some related
discussions.
Language servers~
*vimtex-af-lsp*
In recent years, language servers (LSPs) [0] have become very popular. There
is a language server for LaTeX and bibtex called texlab [1]. It may be
interesting both as an alternative to VimTeX and/or an addition.
There is currently no known conflict between texlab and VimTeX, although
there is some feature overlap. E.g., both texlab and VimTeX provides
advanced completion in various contexts. As texlab is written in Rust and
runs in a separate thread, it is no surprise that it will have a clear
performance advantage. However, VimTeX does use caches to speed up
completion which should in most cases work well.
To use texlab, one must use an LSP client, e.g. |vim-lsp| [2], neovim's
built-in LSP client [3], or |coc-nvim| [4, 5]. See also this VimTeX issue
[6] for more information.
In addition to texlab, there is also a dedicated grammar and spell checking
language server called LTeX [7]. It relies on LanguageTool and supports both
LaTeX and other markup languages. It may be a useful tool to use in
conjunction with VimTeX as an alternative to |vimtex-grammar|.

Options |vimtex-options|
Commands |vimtex-commands|
Map definitions |vimtex-mappings|
Insert mode mappings |vimtex-imaps|
Events |vimtex-events|
------------------------------------------------------------------------------
DEFAULT MAPPINGS *vimtex-default-mappings*
VimTeX is designed to be controlled by a selection of mappings. Note,
though, that most of the mappings are also available as commands, see
|vimtex-commands|.
Many of the mappings utilize the |maplocalleader|. The right-hand sides are
provided as <plug>-mappings, see |using-<plug>|. For any given <plug> map, the
default mapping will only be created if it does not already exist. This means
that if a user defines a custom mapping, e.g. with >
nmap <space>li <plug>(vimtex-info)
then the corresponding default left-hand side will not be mapped.
If one prefers, one may disable all the default mappings through the option
|g:vimtex_mappings_enabled|. Custom mappings for all desired features must
then be defined through the listed RHS <plug>-maps or by mapping the available
commands.
In the below list of mappings, LHS is the default mapping, RHS is the
corresponding <plug>-maps, and MODE indicates in which vim mode the mappings
are valid. See |map-modes| for an explanation of the various modes. The
indicator refers to the prefix of the corresponding map command, e.g. `n`
refers to an |nmap|, `nx` refers to both |nmap| and |xmap|, and so on.
In addition to the mappings listed below, VimTeX provides convenient insert
mode mappings to make it easier and faster to type mathematical equations.
This feature is explained in more detail later, see |vimtex-imaps|.

The default value shows which entries may be changed. Here the different
keys are explained in more detail:
build_dir~
This option sets the compilation build directory. It corresponds to the
`-output-directory` option in `latexmk`. If the path is a relative path,
then it will be considered relative to the main project file.
Although the value of this option should be a string that represents
a path, it is also possible to make it a function. This makes it possible
to specify a dynamic `build_dir`. It may be easier to understand from an
example: >
let g:vimtex_compiler_latexmk = {'build_dir': {-> expand("%:t:r")}}
<
With the above setting, the `build_dir` is set to the base name of the
current file. E.g., If you do `vim test.tex`, the value becomes `test`.
If `build_dir` is specified, then the specified build directory is created
if it does not exist.
Note 1: This option only works with `latexmk` version 4.27 and later.
Note 2: If `$out_dir` is added to `.latexmkrc`, then the `.latexmkrc` setting
will have priority.
Note 3: If |$VIMTEX_OUTPUT_DIRECTORY| is defined, it will have the highest
priority.
callback~
If enabled, this option tells `latexmk` to run |vimtex#compiler#callback|
after compilation is finished.
continuous~
If enabled, `latexmk` will run in continuous mode, i.e. with the `-pvc`
argument. This means that the document is compiled automatically by
`latexmk` every time a related file has been changed, until the processes
is stopped.
If disabled, `latexmk` will run single shot compilations.
Note: The events |VimtexEventCompileStarted| and |VimtexEventCompileStopped|
are only relevant when this option is enabled.
executable~
The name/path to the `latexmk` executable.
hooks~
A list of |Funcref|s. If running in continuous mode, each hook will be
called for each line of output from `latexmk`, with that line as argument.
E.g., to show information about the compilation run numbers, one could do
this: >
function! Callback(msg)
let l:m = matchlist(a:msg, '\vRun number (\d+) of rule ''(.*)''')
if !empty(l:m)
echomsg l:m[2] . ' (' . l:m[1] . ')'
endif
endfunction
let g:vimtex_compiler_latexmk = { 'hooks': [function('Callback')] }

This is a list of options that are passed to `latexmk`. The default
