Oh fantastic, can any of #489 be incorporated too or is that separate?

[fturmel]

Interesting timing, I was just about to ask if I could pick up #489. Should I still? I think it's very powerful to have a bulk normalizing / grouping / renaming pass when the Gatsby nodes get created for both topics and languages in addition to correcting the sources when possible.

[shiffman]

Yes, I'd love to do both! I'm traveling today so can't easily review and merge things, but will be back online later tonight / tomorrow.

[dipamsen]

@fturmel Just in case this is helpful, here are the original variations of languages which I have normalised (with the currently used versions at the beginning):

p5.js / p5js
ml5.js / ml5
Java / java
Processing / processing
JavaScript / javascript / Javascript
node.js / Node.js

[fturmel]

@dipamsen Thanks for that!

[shiffman]

I'm going to go ahead and merge this and we can tackle #489 next! @fturmel if you work on it would you mind forking that branch so that @M0nica's commits are included in the repo history? Thank you!!
