Sample for parsing comments

[jorgeleo]

hi,

I was looking for example of parsing comments.

Single line // And this will be a comment

And multiline

/*
 Comment
*/*
   Still a comment
 */
Closing of the second comment, but still in the first comment
*/

Might require some "counting" and a custom parser context to maintain this counter.

Example in Fluid: https://github.com/sebastienros/fluid/blob/main/Fluid/FluidParser.cs#L226-L247

This is the context class: https://github.com/sebastienros/fluid/blob/main/Fluid/Parser/FluidParseContext.cs

The idea is that when you find /* you increment a counter and decrement it when you find */. But the result of the parser can differ if the counter is back to zero. And if you reach EOF while the counter is positive then everything is a comment, or you can return an error.
