CMakeLint

cmakelint parses CMake files and reports style issues.

cmakelint requires Python.

Installation

To install cmakelint from PyPI, run:

.. code-block:: bash

$ pip install cmakelint

Usage

Syntax: cmakelint [--config=file] [--filter=-x,+y] <file> [file] ...
filter=-x,+y,...
  Specify a comma separated list of filters to apply

config=file
  Use the given file for configuration. By default the file
  $PWD/.cmakelintrc, ~/.config/cmakelintrc, $XDG_CONFIG_DIR/cmakelintrc or
  ~/.cmakelintrc is used if it exists. Use the value "None" to use no
  configuration file (./None for a file called literally None) Only the
  option "filter=" is currently supported in this file.

Run the --filter= option with no filter to see available options. Currently these are:

convention/filename
linelength
package/consistency
readability/logic
readability/mixedcase
readability/wonkycase
syntax
whitespace/eol
whitespace/extra
whitespace/indent
whitespace/mismatch
whitespace/newline
whitespace/tabs

An example .cmakelintrc file would be as follows:

filter=-whitespace/indent

With this file in your home directory, running these commands would have the same effect:

cmakelint.py CMakeLists.txt
cmakelint.py --filter=-whitespace/indent CMakeLists.txt

Filters can optionally be directly enabled/disabled from within a CMake file, overriding the configuration from file or CLI argument:

# lint_cmake: <+ or -><filter name>
# e.g.:
# lint_cmake: -readability/wonkycase
# add multiple filters as list:
# lint_cmake: <+/-><filter1>, <+/-><filter2>

cmakelint can also be run with pre-commit. Add the following configuration block to your .pre-commit-config.yaml:

  - repo: https://github.com/cmake-lint/cmake-lint
    hooks:
      - id: cmakelint

Output status codes

The program should exit with the following status codes:

• 0 if everything went fine
• 1 if an error message was issued
• 32 on usage error
