updating included files even in case of compilation error

[akiran]

As of now, included files are updated only if compilation is successful and it is empty if compilation fails.

Is is possible to update included files even in case of compilation error.
This feature is required in watcher tools, where compilation temporarily enters error state while typing code.

I guess what you actually want is to query that list before the compile step is taking place. This way you could retrieve that information without triggering any compiling issues. Am I right? Be aware that this could still fail, but only if there are problems resolving the imports etc. and not with compilation issues.

@akhleung Can you confirm that imports are fully resolved before compilation? Or is there some way to add more includes during the compilation phase? If not I would propose the fallowing:

• Split compile_file/string (in context.cpp) into parse and compile steps. Add some API functions to just call the parse step to query the included files afterwards.
• Set the included files array on the result before the compilation step, so it contains something even in case of compilation errors.

Added a commit to the C API refactoring PR!
This should enable implementors to do what @akiran was asking for!

[akiran]

yes, ability to query the list before compile step will solve our problem at webpack-contrib/sass-loader#29

@mgreter +1 for your two step proposal.
Having api functions to parse dependencies and also updating included files in case of errors is very useful.

This should be fixed by 2a57715
Added example to the API Documentation
