What kind of help do you need?
If you have question(s) related with PostCSS, you can address them to @ai

[cvrebert]

It's just a matter of finding the time. I don't anticipate any special difficulties.

@cvrebert @ai i try to run the following command:
postcss --use mq4-hover-shim.postprocessorFor --mq4-hover-shim.postprocessorFor.hoverSelectorPrefix ".bs-true-hover " -o dist/css/bootstrap.css dist/css/bootstrap.css
Do i use the wrong command or does it not work? Thanks.

[cvrebert]

Doubt it would work, because of this issue.

[bassjobsen]

@ai as far i do understand --use mq4-hover-shim.postprocessorFor calls require('./q4-hover-shim.postprocessorFor'); in stead of var plugin = require('./q4-hover-shim'); plugin.postprocessorFor(). How should this be solved?

[cvrebert]

@bassjobsen mq4-hover-shim doesn't yet implement the plugin interface expected by postcss. PostCSS is not at fault.

[bassjobsen]

Hi @cvrebert yes i have seen that. But when using --use mq4-hover-shim.postprocessorFor i got Error: Cannot find module 'mq4-hover-shim.postprocessorFor' so the wrong interface is never reached in the first place.

[cvrebert]

postcss-cli is maintained by other folks, not by ai.

[bassjobsen]

yes, i see now. So @pirxpilot can you help?

[pirxpilot]

Not sure how I can help: as soon as mq4-hover-shim implements standard plugin interface it should work with postcss-cli and other runners without any problems.

[bassjobsen]

Hi @pirxpilot thanks for your quick response. Yes i do understand the plugin interface should be implement here: https://github.com/twbs/mq4-hover-shim/blob/master/src/nodejs/postprocessor.js#L72 Currently i found the problem at https://github.com/twbs/mq4-hover-shim/blob/master/src/nodejs/index.js#L9. The preceding means on should use nd --use mq4-hover-shim.postprocessorFor which seems non possible. Or should mq4-hover-shim refactor the index.js too?
