cmake-format can format your listfiles nicely so that they don't look
like crap.
Install from pypi using pip:
pip install --user cmake_format
or:
sudo pip install cmake_format
usage: cmake-format [-h] [-i] [-o OUTFILE_PATH] [-c CONFIG_FILE]
infilepaths [infilepaths ...]
Parse cmake listfiles and format them nicely.
positional arguments:
infilepaths
optional arguments:
-h, --help show this help message and exit
-i, --in-place
-o OUTFILE_PATH, --outfile-path OUTFILE_PATH
Where to write the formatted file. Default is stdout.
-c CONFIG_FILE, --config-file CONFIG_FILE
path to yaml config
cmake-format accepts configuration files in yaml or json format. An example
configuration file is given here. Additional flags and additional kwargs will
help cmake_format to break up your custom commands in a pleasant way.
# How wide to allow formatted cmake files
line_width: 80
# How many spaces to tab for indent
tab_size: 2
# If arglists are longer than this, break them always.
max_subargs_per_line: 3
# Additional FLAGS and KWARGS for custom commands
additional_commands:
foo:
flags: [BAR, BAZ]
kwargs:
HEADERS : '*'
SOURCES : '*'
DEPENDS : '*'You may specify a path to a configuration file with the --config-file
command line option. Otherwise, cmake-format will search the ancestry
of each infilepath looking for a configuration file to use. If no
configuration file is found it will use sensible defaults.
A automatically detected configuration file may be named any of the following:
.cmake-formatcmake-format.yamlcmake-format.json
