Hello, developers! Parentheses in config.scm obstruct reading. Gedit does not highlight them, geany does not exists in guix, emacs highlights, but it is buggie: when I press c-x u many times this causes segmentation fault and it crushes.

Which text editor from guixsd repository can highlight guile parentheses?

I suspect most Guix developers use Emacs with the Geiser mode for enhanced
Scheme integration.

A segfault on "C-x u"? (you mean undo?)  Very strange.  Can you reproduce a
specific recipe?  Is it just in Guile files?  What minor modes are you running?
Is it terminal or graphical Emacs?

Note that if you have a US QWERTY layout, you might prefer "C-/" to undo.

I use vim with no highlighting. We also have edi as a code editor. I
haven't tried it out too much though, or with guix.

I've installed `guix package -i emacs-geiser` and open `emacs /etc/config.scm`
Then 'M-x run-geiser' and it displayed in a half-window scree scheme. Here pic: http://0x0.st/s004.png
Video shows much better code editing: https://www.youtube.com/watch?v=T6jGBWfqafc <https://www.youtube.com/watch?v=T6jGBWfqafc>
There parentheses are colored and auto-complementing.
But I cannot find instruction how to configure that in qwant.

One more: when I've installed guile-emacs, emacs was starting for 30 seconds. I deleted guile-emacs, and now emacsstarts quickly (1-2 seconds). But I think it works slower than geany. I need info how disable unnecessary stuff.

How fast does Emacs start when run as `emacs -Q`?
You can check the startup time by running `M-x emacs-init-time`.  (`M-x` could mean
Alt-x on your keyboard).

Do you have an ~/.emacs.d folder or a ~/.emacs file?  You might want to inspect
those.

You can also install emacs-esup, then run `M-x esup` to profile your startup
times.

Finally, vanilla Emacs is very fast, it should not lag.
Can you tell a difference with or without Geiser?

Not that if you only want basic Scheme support, Emacs provides it out of the
box, without Geiser.

I used Emacs with some mode for parens highlighting

Now that I'm on Xubuntu (and when I was on Fedora) I used Gedit with a
setting to highlight parenses

Maybe it can be compiled in such a way to offer such setting in its
settings window ?

I don't know

This is a shot of the Gedit settings window on Xubuntu, see the last
checkbox on the bottom ?

Hello znavko,

Weird, I use Gedit and it's OK for parentheses in 'config.scm'. Maybe remove and re-install Gedit?

Thank you, Catonano! There are such options in Gedit!

Comparing with that highlighting in emacs (left) http://0x0.st/s004.png <http://0x0.st/s004.png>
this gedit highlighting is so poor.

I need info how to activate parentheses highlighting in Emacs, and may be configure exactly as in my pic left side.

I believe Vim provides syntax highlighting and autoidenting for Scheme,
as well as paredit.vim:

vim does have a scheme module, in
$out/share/vim/vim81/syntax/scheme.vim, and guix's code base gets
recongized as scheme code. I meant that when I have my cursor over a
parenthesis it highlights the other side, but that they're not color
coded or something.

The indenting does work fairly well with the default scheme.vim that
learning vimscript for the purpose of creating a guix.vim has been
backburnered for more than 2 years.

You probably want guix package -i emacs-rainbow-delimiters.

(add-hook 'scheme-mode-hook 'rainbow-delimiters-mode)
(add-hook 'emacs-lisp-mode-hook 'rainbow-delimiters-mode)

Also you probably don't want to use the standard emacs theme.  It's
ugly.  You should try zenburn-theme.  

M-x list-packages RET

Install zenburn-theme.  (It's one of the better ones https://github.com/bbatsov/zenburn-emacs).

Tweaking your Emacs takes a lifetime.  :)

You might also want to try an Emacs distribution:

- Spacemacs is beautiful!  http://spacemacs.org/
- prelude https://github.com/bbatsov/prelude
- Graphene https://github.com/rdallasgray/graphene
- Emacs Bootstrap http://emacs-bootstrap.com/
- Frontmacs https://github.com/thefrontside/frontmacs
- Steve Purcell's config https://github.com/purcell/emacs.d
  I personally cloned his a long time ago.

Slap (show-paren-mode) in your ~/.emacs :-). You'll also want
(electric-pair-mode). Also try paredit, it makes editing Lisp/Scheme much
more pleasant.

HTH,
