Let's chat about lem development

I guess it's around here.

The ncurses backend uses an attribute here

Hey!
I just installed lem.

But I can't seem to M-x like in emacs

Is this specific to me?

madhu

@m4zzz

But I can't seem to M-x like in emacs

that is, I can't type commands.

madhu

@m4zzz

I found that setting "left option key" to "Esc+" instead of "meta" in the iterm2 preferences allows me to generate a meta key event. Huzzah!

This works.
Thanks!

madhu

@m4zzz

The variable LEM:*IMPLEMENTATION* is unbound

This is the error i got after (swank:create-server :dont-close t)

Any ideas about what caused this?

Shinichi Tanaka

@t-sin

How do you boot lem?

madhu

@m4zzz

from a terminal

installed via roswell

Shinichi Tanaka

@t-sin

oh. It seems normal way.

@cxxxr How do you think about?

This is the error

There's something here.
But I can't understand japanese

Shinichi Tanaka

@t-sin

That window is slime on lem. You want to create-server in slime?

Or it's emacs?

madhu

@m4zzz

Yes.
I want to hack on lem.
So I followed these instructions.
https://github.com/cxxxr/lem/wiki/How-to-hack-on-lem-itself
That's how I got this error.

Shinichi Tanaka

@t-sin

I got it.
lem needs its "frontend", physical window abstraction, but lem has no emacs frontend so this error caused.

madhu

@m4zzz

How should I fix this error?

Shinichi Tanaka

@t-sin

wait, I check the instruction. I forgot to do that :innocent:

Shinichi Tanaka

@t-sin

You should do like this:

in terminal, run SBCL REPL via roswell with ros run
(ql:quickload '(:lem-ncurses :swank)) in SBCL REPL
(swank:create-server) in SBCL REPL
(lem:lem) in SBCL REPL, then lem will be started
in Emacs, start slime
in slime, M-x slime-connect

after this, you can see lem's symbols via Emacs slime!

(why fails the wiki way...)

madhu

@m4zzz

It works now!

Thank you very much.

Hello, I tweaked a command line argument in lib/core/lem.lisp. What's the best way to run Lem to try my change?
Am I obliged to build it with ./bootstrap and ./configure or is there a way to run it as a script?
thanks

cxxxr

@cxxxr

There is no script unless you prepare it with ros init etc.

For now, I think it's better to do ros install lem and then lem

vindarel

@vindarel_gitlab

OK (and then ./lem, created at the project root).
(having another issue when running ./lem, it finds an old version of ASDF somewhere in my filesystem)

vindarel

@vindarel_gitlab

caught 1 fatal ERROR conditionvince/bacasable/asdf-sphinx-test/asdf.asd" and have an older version of ASDF (and older than 2.27 at that)

but that asdf-sphinx-test directory does NOT exist O_o
I tried a make clean.
(BTW this error and the backtrace are displayed in the ncurses window, unusable then. I expected it to be on stdout)

vindarel

@vindarel_gitlab

I can start Lem with a REPL with lem --eval "(lem-lisp-mode:start-lisp-repl)".
However the window is split in two. How would you make the REPL fullscreen from the start?

cxxxr

@cxxxr

I've just added an argument to start-lisp-repl

lem-project/lem@7abd7eb

(lem-lisp-mode:start-lisp-repl t)

vindarel

@vindarel_gitlab

Very nice, thanks!

Hi everyone, I am new to the lisp world. I am doing a project on the side and I got to try roswell. But I am having problems setting up correctly with quicklisp

I have asked the question on stackoverflow recently and was redirected here: https://stackoverflow.com/questions/66623854/quickload-fails-to-load-local-project-using-roswell?noredirect=1#comment117797506_66623854

@svetlyak40wt

@achrafmam2 Roswell initializes Quicklisp for you. If you want your software to have reproducible builds, don't use local-projects. Fix all requirements using Qlot's (https://github.com/fukamachi/qlot) qlfile.lock, or CLPM (https://gitlab.common-lisp.net/clpm/clpm) lock.

@achrafmam2

Sweet thanks @svetlyak40wt

Quick question, what is the difference between SLIME and LEM?

Alexander Artemenko

@svetlyak40wt

SLIME is a client-server protocol, CL library (called SWANK) and Emacs extension to communicate with CL process.

Lem is Emacs reimplemented in Common Lisp. You can play with REPL connected to the Lem itself, or connect to a separate CL process, running SLIME server.

There is also SLIME's fork called SLY (https://github.com/joaotavora/sly) which has cool features. I prefer SLY, but Lem is unable to connect to the CL process running SLYNK server (analog of SLIME's SWANK).

Andrew

@commander-trashdin

I was trying to run lem via just quickloading it and (lem:lem). I get

The value
  LEM-LISP-MODE.AUTODOC::LISP-INSERT-SPACE-AND-AUTODOC
is not of type
  HASH-TABLE

Is this normal?

Andrew

@commander-trashdin

Apparently it comes from define-key-internal function where there's table which is not a hash-table at all.

Well done for the new release, Lem developers!
I will party with you, even though I'll remark that there is no release notes in the Github release and that the Changelog was last changed 9 months ago ;)
(you added a shell mode? Nice. What does it do?)
A point on documentation I wanted to raise earlier: what about saying in the README that Lem supports other programming languages? I'd send a PR but I don't know enough their support status, and I'd send a big PR which may not be of the taste of Lem developers :p

While I'm at it. I'd love to see more self-documenting features in Lem, à la Emacs. If there are some, they are not documented, so it slows Lem adoption down. Would it help to sponsor this specific issue on OpenCollective?
Best regards
