CMake commands are sometimes given in upper and lower case.
Previously uppercase commands had been required but now commands are
case-insensitive and lowercase commands are preferred. Conversion to lowercase
commands have been implemented in other open source projects such as ITK vxl
and BRAINSTools, and is the preferred style for KDE. Consistent style
practices help to improve readability and maintainability of code.
This was implemented with the shell script:
NOTE: MUST USE GNU compliant version of sed
cmake --help-command-list \
| grep -v "cmake version" \
| while read c; do
echo 's/\b'"$(echo $c | tr '[:lower:]' '[:upper:]')"'\(\s*\)(/'"$c"'\1(/g'
done >convert.sed \
&& git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' \
| xargs -0 gsed -i -f convert.sed \
&& rm convert.sed
This is a reimplementation of ITK commit
