Column number support #3

Open joshprice opened 8 years ago

This is currently needed for precise error messages in both https://github.com/graphql-elixir/graphql and https://github.com/absinthe-graphql/absinthe.

I also miss column number support.

rvirding commented 4 years ago

Hmm, is the first character in a line in column 0 or 1? And do you treat tabs as one character or "pad" them out to the next 8th position? Just thinking out loud really.

Don't know if it is still relevant, but I've implemented column number support as this year's Spawnfest project. Started counting columns at 1 and I've set the default tab size to 8, but left the possibility to configure it to your needs. The project can be found here. Any feedback is very welcome :D
