gcov2perl - convert gcov files to Devel::Cover databases VERSION
version 1.03 SYNOPSIS
gcov2perl -h -i -v -db database gcov_files DESCRIPTION
Convert gcov files to Devel::Cover databases. OPTIONS
The following command line options are supported: -db database - specify the database to use -h -help - show help -i -info - show documentation -v -version - show version DETAILS
To obtain coverage of XS files they must first be compiled with the appropriate options. In a standard Makefile environment, such as that created by ExtUtils::MakeMaker, this can be accomplished with the command: HARNESS_PERL_SWITCHES=-MDevel::Cover make test CCFLAGS=-O0 -fprofile-arcs -ftest-coverage OTHERLDFLAGS=-fprofile-arcs -ftest-coverage If you have already built your object files it may be necessary to run make clean first, or to find some other way to ensure that they get rebuilt with the options gcov requires. Now the code coverage data has been collected "gcov" needs to be run: gcov Mylib.xs This will create one or more gcov files on which you can run "gcov2perl": gcov2perl Mylib.xs.gcov Finally, "cover" should be run as usual with any options required: cover If you are running everything with standard options, you can do all this with one command: cover -test EXIT STATUS
The following exit values are returned: 0 All files converted successfully >0 An error occurred. SEE ALSO

cover - report coverage statistics VERSION
version 0.89 SYNOPSIS
cover -help -info -version -summary -report report_format -outputdir dir -select filename -ignore filename -select_re RE -ignore_re RE -write [db] -delete -dump_db -launch -silent -coverage criterion -test -gcov -make [make] -add_uncoverable_point -delete_uncoverable_point -clean_uncoverable_points -uncoverable_file [report specific options] coverage_database [coverage_database ...] DESCRIPTION
Report coverage statistics in a variety of formats. The summary option produces a short textual summary. Other reports are available by using the report option. The following reports are currently available: text - detailed textual summary html - detailed HTML reports OPTIONS
The following command line options are supported: -h -help - show help -i -info - show documentation -v -version - show version -silent - don't print informational messages (default off) -summary - give summary report (default on) -report report_format - report format (default html) -outputdir - directory for output (default db) -launch - launch report in viewer (if avail) (default off) -select filename - only report on the file (default all) -ignore filename - don't report on the file (default none) -select_re RE - append to REs of files to select (default none) -ignore_re RE - append to REs of files to ignore (default none) -write [db] - write the merged database (default off) -delete - drop database(s) (default off) -dump_db - dump database(s) (for debugging) (default off) -coverage criterion - report on criterion (default all available) -test - drop database(s) and run make test (default off) -gcov - run gcov to cover XS code (default on if using gcc) -make make_prog - use the given 'make' program for 'make test' other options specific to the report format REPORT FORMATS
Tool accepts -report option: html|html_minimal (default) HTML reporting. Percentage thresholds are color-coded and configurable via -report_c0 <integer>, -report_c1 <integer> and -report_c2 <integer>.: 0% 75% 90% 100% | .. | .. | .. | <c0 <c1 <c2 c3 red yellow orange green html_basic HTML reporting with syntax highlighting if PPI::HTML or Perl::Tidy module is detected. Like html|html_minimal reporting, percentage thresholds are color-coded and configurable. text Plain text reporting. compilation Like text but hacked to give a minimal output in a format similar to that output by Perl itself so that it's easier to step through the untested locations with Emacs compilation mode. DETAILS
Any number of coverage databases may be specified on the command line. These databases will be merged and the reports will be based on the merged information. If no databases are specified the default database (cover_db) will be used. The -write option will write out the merged database. If no name is given for the new database, the first database read in will be overwritten. When this option is used no reports are generated by default. Specify -select and -ignore options to report on specific files. Specify -coverage options to report on specific criteria. By default all available information on all criteria in all files will be reported. Available coverage options are statement, branch, condition, subroutine, and pod. However, if you know you only want coverage information for certain criteria it is better to only collect data for those criteria in the first place by specifying them at that point. This will make the data collection and reporting processes faster and less memory intensive. See the documentation for Devel::Cover for more information. The -test option will delete the databases and run your tests to generate new coverage data before reporting on it. Devel::Cover knows how to work with standard Perl Makefiles as well as Module::Build based distributions. For detailed instructions see the documentation for ExtUtils::MakeMaker at https://metacpan.org/module/ExtUtils::MakeMaker or for Module::Build at https://metacpan.org/module/Module::Build both of which come as standard in recent Perl distributions. The -gcov option will try to run gcov on any XS code. This requires that you are using gcc of course. If you are using the -test option will be turned on by default. EXIT STATUS
The following exit values are returned: 0 All operations were completed successfully. >0 An error occurred. SEE ALSO
