coffeelint-multiple-callback v0.0.7
coffeelint-multiple-callback
CoffeeLint rule that finds instances where callbacks might be called more than once or not at all.
This code is in the very early stages of development. If you find cases where it's broken, please add example test fixtures. For lines in tests that should trigger an error, add the comment # HIT
to the end of the line. The tests go through line by line and verify that lines with that comment trigger a linting error and all other lines do not.
Examples
These functions have the potential of calling cb() multiple times, and is likely an error:
badFunc = (err, cb)->
cb err
cb err # BAD
return
badIf = (err, cb)->
if err
cb err
cb null # BAD
return
These functions are okay, since they only call the callback once no matter how the logic runs:
goodIf = (err, cb)->
if err
cb err
else
cb null
return
goodIf2 = (err, cb)->
if err
cb err
return
cb null
return

I don't know what I'm doing. I just jumped in with an idea and tried to get it to work. Please assist if this is something you understand or have ideas on how to handle this better.
