NAME¶

lcovrc - lcov configuration file

DESCRIPTION¶

The lcovrc file contains configuration information for the lcov code coverage tool (see lcov(1)). The system-wide configuration file is located at /etc/lcovrc. To change settings for a single user, place a customized copy of this file at location ~/.lcovrc. Where available, command-line options override configuration file settings. Lines in a configuration file can either be:

*

empty lines or lines consisting only of white space characters. These lines are ignored.

*

comment lines which start with a hash sign ('#'). These are treated like empty lines and will be ignored.

*

statements in the form 'key = value'. A list of valid statements and their description can be found in section 'OPTIONS' below.

OPTIONS¶

genhtml_css_file = filename

Specify an external style sheet file. Use this option to modify the appearance of the HTML output as generated by genhtml. During output generation, a copy of this file will be placed in the output directory.

 

 

This option corresponds to the --css-file command line option of genhtml.

 

 

By default, a standard CSS file is generated.

genhtml_hi_limit = hi_limit genhtml_med_limit = med_limit

Specify coverage rate limits for classifying file entries. Use this option to modify the coverage rates (in percent) for line, function and branch 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 90 and 75 percent.

genhtml_line_field_width = number_of_characters

Specify the width (in characters) of the source code view column containing line coverage information.

 

 

Default is 12.

genhtml_branch_field_width = number_of_characters

Specify the width (in characters) of the source code view column containing branch coverage information.

 

 

Default is 16.

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.

genhtml_branch_coverage = 0|1

If non-zero, include branch coverage data when generating HTML output using genhtml.

 

 

This option can be set to 0 by using the --no-branch-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_list_full_path = 0|1

If non-zero, print the full path to source code files during a list operation.

 

 

This option corresponds to the --list-full-path option of lcov.

Default is 80.

lcov_list_truncate_max = percentage

Specify the maximum percentage of file names which may be truncated when choosing a directory prefix in list output. This value is ignored when lcov_list_full_path is non-zero.

 

 

Default is 20.
