* Provide an empty coverage report when package has no coverage
- When covering a project with multiple packages, the project coverage report
will produce a table of individual coverage reports for each package. The
links in this table don't go anywhere when a package is uncovered (they are
broken links).
- By producing an empty coverage report when a package has no coverage, we fix
the broken links, and provide a tad more information about the coverage
state of that package.
* Improve project coverage report index page
- Provide a link to the union/all coverage report.
- Format the reports as a list instead of a table of one column.
- Provide better explanation of what each report means.
* Add warning explaining modules with no coverage
- Modules that have no coverage at all are simply not included in the HTML
reports generated by HPC.
- Add a warning to the project coverage report index page so users are aware of
this limitation of HPC.
* Simplify interface of coverageReport
- Remove the concept of "package boundaries" from the "coverageReport" function.
- The "coverageReport" is now a function of:
- arbitrary checks generating tix files
- arbitrary mix modules
- This more closely reflects the usage of hpc, which doesn't care about package
boundaries.
- Use this new "coverageReport" function to simplify the "projectCoverageReport"
implementation. A project coverage report now simply:
- copies out constituent coverage reports.
- writes out an "all coverage report" using all checks in the project and all
mix modules..
- writes out a summary index page.
since it needs custom shell setup and knowledge not wanted/necessary for
many project. cabalWrapper can still be used from iohk-nix, until
underlying issue is handled natively by cabal.
Also remove packagesExes materialization attributes,
not really useful anymore, given faster evaluation of recent haskell.nix
- This allows nix run to work correctly, so that it knows the correct
name of the executable, as it would otherwise attempt to execute an
executable named "project-name-exe-exeName", for example.
- See #1231.
