guile-parser-combinators as new dependency to guix import quicklisp

guile-parser-combinators as new dependency to guix import quicklisp

[swedebugia]

Hi

This morning I began to write a quicklisp importer using Daves 
guile-parser-combinators [1] to create a parser for the 
space-separated-csv files.

guile-parser-combinators [2] is really nice, thanks Dave!, but not yet 
in guix.

Any thoughts on using this?

In general we have to think twice before adding new dependencies to
Guix.  To parse CSV files, I think you can probably do using the string
utilities already available in Guile; that would avoid adding a new
dependency.

WDYT?

(That said I agree that Dave’s parser combinators are nice, perhaps time
to add a package for them?  :-))

Thanks,
Ludo’.

I would like to note that (ice-9 peg) is part of Guile and could be used
as an alternative to build a simple parser.  It has a different feel
than guile-parser-combinators, of course, but I thought I’d mention it
anyway.

Thanks for sharing your thoughts on this.

I try to hack together a PEG-parser then given that this code is in 2.2.

Are there any PEG-parser examples I can look at in/outside Guix?

Julien (roptat on IRC) has just written an opam importer using (ice-9
peg).
