Better way to fix mocha lcov output using sed

Due to the know prob of mocha-lcov-mocha breaking file paths, I need to fix the current output paths that looks like this:

SF:Vis/test-Guid.coffee
SF:Vis/Guid.coffee
SF:Vis/test-Vis-Edge.coffee
SF:Vis/Vis-Edge.coffee

into

SF:test/Vis/test-Guid.coffee
SF:src/Vis/Guid.coffee
SF:test/Vis/test-Vis-Edge.coffee
SF:src/Vis/Vis-Edge.coffee

I'm not very good with sed, but I got it to work using:

mocha -R mocha-lcov-reporter _coverage/test --recursive | sed 's,SF:,SF:src/,' | sed s',SF.*test.*,SF:test//&,' | sed s',/SF:,,' | sed s',test/src,test,' | ./node_modules/coveralls/bin/coveralls.js

which is basically doing 4 sed commands in sequence

sed 's,SF:,SF:src/,' 
sed s',SF.*test.*,SF:test//&,'
sed s',/SF:,,' 
sed s',test/src,test,'

my question is if there is a way to do with this one sed command, or use another osx/linux command line tool

Solution

  • Initially put "src/" after every ":" and then if "test" is found on the line replace "src" with "test":

    $ sed 's,:,:src/,;/test/s,src,test,' file
SF:test/Vis/test-Guid.coffee
SF:src/Vis/Guid.coffee
SF:test/Vis/test-Vis-Edge.coffee
SF:src/Vis/Vis-Edge.coffee
