[buptmiao]

I think this feature is very usefull.

It is useful. For example here.

Thanks. I saw this work around, but it is too boring if there are too many reserved words.

Quoting an answer from stackoverflow

You could set case-insensitivity in the .l file:

%option caseless

You could call flex -i.

Or you could state individual rules to be case-insensitive:

(?i:word)

Which of these options would be helpful in your use case?

[buptmiao]

I use the option below in flex.

%option case-insensitive

@buptmiao Please try checking out cznic/lex branch case-insensitive, then rebuild cznic/golex and test with some .l source. I did not actually tested if it works whatsoever, so please provide feedback. Thank you.

[buptmiao]

You are so great! It works now.

Thanks for testing it!
