Hello! I am glad to announce a new command-line tool which should make development
 a little easier.

Program, compiled with `-cov` switch, generates *.lst files. They contain program source, number of executions of each line and total code coverage of the file.
Those files are quite useful for small programs/libraries, but not that useful for big ones.

Covered processes *.lst files, and reports only useful information. Behaviour can be changed with command-line options:

  '--coverage' reports code coverage in % for each file.
  '--blame' shows list of files ordered by code coverage.
  '--average' reports average code coverage for files.

Covered works for lists of files and directories, so '--blame' can be used to find less covered files, and '--average' to compute average code coverage of the project.

More documentation is available on project page on GitHub: https://github.com/ohdatboi/covered
It is also added to DUB package registry: http://code.dlang.org/packages/covered

Also, I am looking for huge projects, so I can test covered on them. Reply here or start an issue on GitHub if you know one.

You could add a mixin template that injects the "version(D_Coverage)" code.

Covered is a standalone tool, not intended to be used as a library. I don't think that forcing user to add it as dependency is a good idea, as well as messing with user's code (It is possible that `dmd_coverDestPath` is already overrided).

Nice work!

I would like to contribute to such a tool :) I was working at something similar with trial( http://trial.szabobogdan.com/ ), and I would like to include your library if it's possible.


this is a sample code coverage report:

Thanks! Yes, module "covered.loader" can be used, but it isn't complete yet. I'll start working on v1.0.0 tomorrow, changing current design (get as much information as possible and store it) to a new one (get only required information). This will increase speed and decrease memory usage.

Nice! I'm using unit-threaded, but trial looks even better. I'll try it tomorrow.

v1.0.0-alpha.1 is released. I'll release v1.0.0 as soon as I add some documentation, but I won't change API again, so it is ready to be used as a library.
Also, I've done some benchmarks: https://github.com/ohdatboi/covered/releases/tag/v1.0.0-alpha.1
