cmmerge – merging utility
cmmerge is a small utility which lets you merge several instrumentation databases (
.csmes file) together. It behaves like the CoverageBrowser menu entry File > Merge with (see Merging instrumentations).
-o <outfile> <infile>...
cmmerge --blackbox -o <outfile> <infile>...
.csmesoutput file. (Required.)
.csmesinput file. Only one input file is allowed if
-b | --blackbox: Generate a
.csmesfile for black-box testing.
- <options>: Any of:
-a | --append: Merge the input file(s) with the existing content of the output file. <outfile> must already exist.
--instrumentation-and-execution=<reference>: Include only execution results that belong to the
With this option,
cmmergemerges <reference> with the <infile>s, but includes the instrumentations and executions of an <infile> only if they also occur in <reference>. If
--appendis set, <outfile> is viewed as a part of <reference>.
This option is useful for unit tests, where <reference> is the program for which the test is written, while <infile>s contain the execution results of the unit tests.
--reviews-only=<reference>: Merge <reference> with the comments and manual validations in the <infile>s.
The file <reference> is a
.csmesfile. Only validations and comments of unmodified functions are imported. If there are comments for the same line of code, they are merged. The original comments are then separated by a horizontal bar. If the same comment occurs more than once in the input files, only one copy is kept.
-s | --strict: Require that the preprocessed output for each C++ file is identical across the build.
--delete: Delete the input files from disk after importing them.
-v | --verbose: Verbose output.
@<path>: Read command line options from the file at <path> and insert them at the position of this option. The option file is a text file with one option per line. Leading and trailing blanks and empty lines are ignored.
