b/g:pylint_makeprg_params variable.  For example: >

	let b:pylint_makeprg_params = "--max-line-length "..&textwidth

The global default is "--jobs=0" to use (almost) all cores.

PYUNIT COMPILER						*compiler-pyunit*

This is not actually a compiler, but a unit testing framework for the
Python language.  It is included into standard Python distribution
starting from version 2.0.  For older versions, you can get it from
https://pyunit.sourceforge.net.

When you run your tests with the help of the framework, possible errors
are parsed by Vim and presented for you in quick-fix mode.

Unfortunately, there is no standard way to run the tests.
The alltests.py script seems to be used quite often, that's all.
Useful values for the 'makeprg' options therefore are:
 setlocal makeprg=./alltests.py " Run a testsuite
 setlocal makeprg=python\ %:S   " Run a single testcase

PYTEST COMPILER						*compiler-pytest*
Commonly used compiler options can be added to 'makeprg' by setting the
b/g:pytest_makeprg_params variable.  For example: >

  let b:pytest_makeprg_params = "--verbose --no-summary --disable-warnings"

The global default is "--tb=short --quiet"; Python warnings are suppressed.

TEX COMPILER						*compiler-tex*

Included in the distribution compiler for TeX ($VIMRUNTIME/compiler/tex.vim)
uses make command if possible.  If the compiler finds a file named "Makefile"
or "makefile" in the current directory, it supposes that you want to process
your `*TeX` files with make, and the makefile does the right work.  In this case
compiler sets 'errorformat' for `*TeX` output and leaves 'makeprg' untouched.  If
neither "Makefile" nor "makefile" is found, the compiler will not use make.
You can force the compiler to ignore makefiles by defining
b:tex_ignore_makefile or g:tex_ignore_makefile variable (they are checked for
existence only).

If the compiler chose not to use make, it needs to choose a right program for
processing your input.  If b:tex_flavor or g:tex_flavor (in this precedence)
variable exists, it defines TeX flavor for :make (actually, this is the name
of executed command), and if both variables do not exist, it defaults to
"latex".  For example, while editing chapter2.tex \input-ed from mypaper.tex
written in AMS-TeX: >

	:let b:tex_flavor = 'amstex'
	:compiler tex
<	[editing...] >
	:make mypaper

Note that you must specify a name of the file to process as an argument (to
process the right file when editing \input-ed or \include-ed file; portable
solution for substituting % for no arguments is welcome).  This is not in the
semantics of make, where you specify a target, not source, but you may specify
filename without extension ".tex" and mean this as "make filename.dvi or
filename.pdf or filename.some_result_extension according to compiler".

Note: tex command line syntax is set to usable both for MikTeX (suggestion
by Srinath Avadhanula) and teTeX (checked by Artem Chuprina).  Suggestion
from |errorformat-LaTeX| is too complex to keep it working for different
shells and OSes and also does not allow to use other available TeX options,
if any.  If your TeX doesn't support "-interaction=nonstopmode", please
report it with different means to express \nonstopmode from the command line.

TSC COMPILER						*compiler-tsc*

The executable and compiler options can be added to 'makeprg' by setting the
b/g:tsc_makeprg variable.  For example: >

	let b:tsc_makeprg = "npx tsc --noEmit"

TYPST COMPILER						*compiler-typst*

Vim includes a compiler plugin for Typst files. This compiler is enabled
automatically in Typst buffers by the Typst filetype plugin |ft-typst-plugin|.
Run |:make| to compile the current Typst file.

							*g:typst_cmd*
By default Vim will use "typst" as the command to run the Typst compiler. This
can be changed by setting the |g:typst_cmd| variable: >
	let g:typst_cmd = "/path/to/other/command"
