Summary: Extend --trace to --coverage mode for detection of
"dead" cmake code
Description:
my intention is to find "dead" cmake script code in the project for cleanup and
maintainance of the scripts.
I have adapted the gcovr script to parse the cmake script output in --trace mode
to detected "code coverage" and write text or html output. Results attached
below.
No i have some issues:
- The trace mode does report multi line statements as "one line" statement.
This should be reported as RANGE (e.g. not with just one line number, with start
and end line number (e.g. filename(3:5): )
- the commands closing are not considered in trace output. so to each if(),
macro() or other commands, the enclosing endif(), endmacro() etc are not
"covered". This should be also traced or covered
For complete finalisation is must reload the file and mark the commented and
blank lines as "covered". But thats ok for me for the covering issues.
So my suggestion would be to extend the trace mode or create an additional
coverage mode.
Steps to Reproduce:
cmake with --trace output activated and multiline statements like
set( MY_VAR
test.cpp
test.h
...
)
if( WIN32 )
set( MYVAR2 )
endif()
Additional Information:
The attached files are sample output from the adapted gcovr script.
Script cant be published cause i have to clarify the copyright issues with the
"original" script holders.
