00:27 <BitPuffin> I don't even know if I think elisp itself is the biggest problem with emacs anymore. especially now that it has lexical scope

00:42 <jcowan> The failure of Guilemacs is attributable entirely to the Emacs team, not the Guilers

00:52 <winny> elisp is a pretty challenging language to write robust code in

00:52 <winny> i guess it's mainly the apis that make it challenging

01:20 badkins has quit [Remote host closed the connection]

01:23 badkins has joined #racket

01:28 <BitPuffin> Yeah, I mean it has a decent subset of common lisp and varioua things that makes it good enough at lisping. But yeah can't say the emacs unique apis have been that great to work with in my experience

01:28 badkins has quit [Ping timeout: 252 seconds]

01:30 <BitPuffin> There is also now some annoying ish fragmentation where we had dash and s , the former now sort of replaced by seq-* procedures because for whatever reason we couldn't have dash in core emacs

01:45 evdubs__ is now known as evdubs

03:39 <BitPuffin> although emacs has the wonderful ability to redefine things while running. I really miss that in other systems.

03:40 <BitPuffin> On that topic, could a mildly modified #lang racket support mutable toplevel mayhaps?

03:41 <BitPuffin> Like maybe by redefining define to work a bit differently

10:13 <bremner> BitPuffin: you might want to read "The top level is hopeless". samth collected some relevant links: https://gist.github.com/samth/3083053

10:14 <bremner> I'm not sure that's an answer two your question, exactly.

11:04 <BitPuffin> Been meaning read that

11:04 <BitPuffin> Thanks for reminding me :)

11:11 <BitPuffin> Guile has a mutable toplevel though, and it seems like it would be possible to implement #lang guile or something

11:11 <BitPuffin> Maybe without the mutable toplevel

11:21 <bremner> BitPuffin: have you tried xrepl mode?

11:21 <bremner> err. not mode so much as library for racket

23:11 <countvajhula> hi, I have a question about macros:

23:11 <countvajhula> i have an unhygienic macro A that injects an identifier into the calling environment

23:11 <countvajhula>

23:11 <countvajhula> and another macro B that simply calls A

23:12 <countvajhula> calling A on its own works

23:12 <countvajhula> but calling B doesn't (the calling scope complains about unbound identifier)

23:12 <countvajhula> is there seomthing I need to do in a macro that calls another macro to propagate the calling scope in some way?

23:14 rgherdt_ has quit [Ping timeout: 260 seconds]

23:17 <countvajhula> here's a gist that provides a simple example:

23:17 <countvajhula>

23:17 <countvajhula> https://gist.github.com/countvajhula/42d0d3d35fbce29589bf4f9750a58138

23:21 <countvajhula> feels like it should be a straightforward thing but I haven't been able to get it to work despite trying various things, like wrapping the macro invocation with a datum->syntax in the calling macro

23:21 <countvajhula> any pointers would be appreciated :)
