argument threading macros & combinators for guile

argument threading macros & combinators for guile

[vapnik spaknik]

Hi,
    does anyone know of guile modules containing argument threading macros & combinators, e.g. similar to dash.el & dash-functional.el for elisp?

I have some old ones over here: https://hg.sr.ht/~bjoli/guile-threading-macros

They are written using syntax-rules and I am not sure how well they combine with srfi-26. If srfi 26 exports auxiliary syntax, you won't be able to combine them since that syntax will shadow the unbound syntax <> and <...> used by my macros.


Other than that, we have a srfi called chain that might be finalized soon. That must be srfi 190-something.

I forgot to say, that is a trivial fix! Just import the bindings from srfi 26 and re-export them.

This code can also be used to implement the new srfibchaij macro, although a syntax-case one would be about two billion times shorter (and faster).

Thanks, that looks great Linus. Is there a guix package for them?

I thought about it recently, but with the upcoming srfi-197 (among others, the chain macro) it felt rather pointless. It does absolutely the same thing, and to my surprise I received a "thank you" for valuable input in the srfi document. I happened to suggest the same syntax I had settled on, taken from the cut macro in srfi-26 :)

I will probably submit a patch to guile with srfi-197 whenever it gets finalized. I don't know if Ludo or Andy are interested in including it, but if not it can easily be made a package.
