Cool! I had the same package somewhere, thanks for publishing yours :)
I think there's already a module this could go into. If there isn't (I
will check tomorrow), what about a more generic name which could hold a
class of applications? Just an idea.

I haven't run the code, these are just my initial remarks. Overall it
looks good, so the only criticism is really in the (description).

I'm not sure, but I think the "yylex()" will have to be written as
@code{yylex()} or something similar.

I think "corners of the re2c API." would be correct?

Re: [PATCH v2] gnu: new re2c package, version 0.16

[ng0]

Hi,

I've applied and build this, and I have other remarks:

The commit message should look like this:

gnu: Add re2c.

* gnu/packages/re2c.scm: New file.
* gnu/local.mk (GNU_SYSTEM_MODULES): Add re2c.scm.



The "tested on(...)" is more of a personal note and not needed in the
commit message.

I get no difference to the re2c package I have (identical build) so when
those changes will be applied it's good to go from my side.

I mimicked flex which resides in standalone flex.scm.

Author's spelling:
    https://raw.githubusercontent.com/skvadrik/re2c/gh-pages-gen/src/index.rst

I'm not sure which is right:

Oh. In this case it's okay.

I want someone to double check this. This is an area I don't know much
about, I personally would avoid it and would just write

@code{yylex} style API

but I'd rather would wait for someone who knows more about this.

I've read into rules for the use and omission of articles, and my gut
feeling is that you were right the first time (without "the").
