Specify coverage rate limits for classifying file entries. Use this option to modify the coverage rates (in percent) for line or function coverage at which a result is classified as high, medium or low coverage. This classification affects the color of the corresponding entries on the overview pages of the HTML output: High: hi_limit <= rate <= 100 default color: green Medium: med_limit <= rate < hi_limit default color: orange Low: 0 <= rate < med_limit default color: red Defaults are 50 and 15 percent for line coverage and 90 and 75 percent for function coverage.genhtml_overview_width " =" pixel_size
Specify the width (in pixel) of the overview image created when generating HTML output using the --frames option of genhtml . Default is 80.genhtml_nav_resolution " =" lines
Specify the resolution of overview navigation when generating HTML output using the --frames option of genhtml . This number specifies the maximum difference in lines between the position a user selected from the overview and the position the source code window is scrolled to. Default is 4.genhtml_nav_offset " =" lines
Specify the overview navigation line offset as applied when generating HTML output using the --frames option of genhtml. Clicking a line in the overview image should show the source code view at a position a bit further up, so that the requested line is not the first line in the window. This number specifies that offset. Default is 10.genhtml_keep_descriptions " =" 0 | 1
If non-zero, keep unused test descriptions when generating HTML output using genhtml . This option corresponds to the --keep-descriptions option of genhtml . Default is 0.genhtml_no_prefix " =" 0 | 1
If non-zero, do not try to find and remove a common prefix from directory names. This option corresponds to the --no-prefix option of genhtml . Default is 0.genhtml_no_source " =" 0 | 1
If non-zero, do not create a source code view when generating HTML output using genhtml . This option corresponds to the --no-source option of genhtml . Default is 0.genhtml_num_spaces " =" num
Specify the number of spaces to use as replacement for tab characters in the HTML source code view as generated by genhtml . This option corresponds to the --num-spaces option of genthml . Default is 8.genhtml_highlight " =" 0 | 1
If non-zero, highlight lines with converted-only data in HTML output as generated by genhtml . This option corresponds to the --highlight option of genhtml . Default is 0.genhtml_legend " =" 0 | 1
If non-zero, include a legend explaining the meaning of color coding in the HTML output as generated by genhtml . This option corresponds to the --legend option of genhtml . Default is 0.genhtml_html_prolog " =" filename
If set, include the contents of the specified file at the beginning of HTML output. This option corresponds to the --html-prolog option of genhtml . Default is to use no extra prolog.genhtml_html_epilog " =" filename
If set, include the contents of the specified file at the end of HTML output. This option corresponds to the --html-epilog option of genhtml . Default is to use no extra epilog.genhtml_html_extension " =" extension
If set, use the specified string as filename extension for generated HTML files. This option corresponds to the --html-extension option of genhtml . Default extension is "html".genhtml_html_gzip " =" 0 | 1
If set, compress all html files using gzip. This option corresponds to the --html-gzip option of genhtml . Default extension is 0.genhtml_sort " =" 0 | 1
If non-zero, create overview pages sorted by coverage rates when generating HTML output using genhtml . This option can be set to 0 by using the --no-sort option of genhtml . Default is 1.genhtml_function_coverage " =" 0 | 1
If non-zero, include function coverage data when generating HTML output using genhtml . This option can be set to 0 by using the --no-function-coverage option of genhtml . Default is 1.geninfo_gcov_tool " =" path_to_gcov
Specify the location of the gcov tool (see gcov (1)) which is used to generate coverage information from data files. Default is 'gcov'.geninfo_adjust_testname " =" 0 | 1
If non-zero, adjust test names to include operating system information when capturing coverage data. Default is 0.geninfo_checksum " =" 0 | 1
If non-zero, generate source code checksums when capturing coverage data. Checksums are useful to prevent merging coverage data from incompatible source code versions but checksum generation increases the size of coverage files and the time used to generate those files. This option corresponds to the --checksum and --no-checksum command line option of geninfo . Default is 0.geninfo_compat_libtool " =" 0 | 1
If non-zero, enable libtool compatibility mode. When libtool compatibility mode is enabled, lcov will assume that the source code relating to a .da file located in a directory named ".libs" can be found in its parent directory. This option corresponds to the --compat-libtool and --no-compat-libtool command line option of geninfo . Default is 1.lcov_gcov_dir " =" path_to_kernel_coverage_data
Specify the path to the directory where kernel coverage data can be found. Default is '/proc/gcov'.lcov_insmod_tool " =" path_to_insmod
Specify the location of the insmod tool used to load kernel modules. Default is '/sbin/insmod'.lcov_modprobe_tool " =" path_to_modprobe
Specify the location of the modprobe tool used to load kernel modules. Default is '/sbin/modprobe'.lcov_rmmod_tool " =" path_to_rmmod
Specify the location of the rmmod tool used to unload kernel modules. Default is '/sbin/rmmod'.lcov_tmp_dir " =" temp
Specify the location of a directory used for temporary files. Default is '/tmp'.
/etc/lcovrc The system-wide lcov configuration file.
~/.lcovrc The individual per-user configuration file.
