refresh coverage lines

[juanpabloaj]

I run coverage

coverage run setup.py test

in vim, open coveragepy

 :Coveragepy show

ok. Then I modifify the code and run coverage again (in other terminal, without close vim)

coverage run setup.py test

and hide and show Coveragepy

 :Coveragepy show
 :Coveragepy show

but, the coverages lines don't are updated.

[juanpabloaj]

with

:Coveragepy report

the lines are updates :)

[alfredodeza]

right, :Coveragepy show will only re-read the report, it will not re-process it.

But maybe it should?

[alfredodeza]

ah wait, no, it should not re-process it because processing the report means waiting on coveragepy to read the file and spit out the results:

coverage report -m -i /path/to/coveragepy_report

And that would be just tedious.

This function, refreshing coverage marks without opening report buffer, still seems to be desirable for work on completing test coverage. My typical cycle is: scroll to some uncovered lines, write corresponding unit tests in adjacent split buffer, re-run unit tests under coverage.py. And then I would like to see newly covered lines green and move to the next batch. Using :Coveragepy report for that requires switching to report buffer and closing it, which is just a waste of time on each cycle.

How about adding :Coveragepy refresh command which would invoke coverage report and update coverage marks without opening report window? I already have a patch.

@eprigorodov I like your solution :)

[eprigorodov]

And I like your plugin, it just works and does what was needed. Please have a look at PR #17. Thank you :)
