Anyone doing any fancy customizations of source blocks?

Anyone doing any fancy customizations of source blocks?

[William Denton]

Is anyone doing any fancy formatting of source blocks, such as putting a line
in the left fringe, or a box around them, or having some interesting background?

I ask because I recently changed the theme I use to get the dark Solarized look 
I like,[1] and all of a sudden my #+begin_src lines were underlined and 
#+end_src had a line above it.  These come from org-block-begin-line and 
org-block-end-line, and are shown here, but I'd never noticed them in 
documentation or had them on my screen before:

https://orgmode.org/worg/org-contrib/babel/examples/fontify-src-code-blocks.html

Aside from fontifying the source blocks I've never done anything special about 
them (except wonder how I ever did anything without them), but seeing this made 
me wonder if anyone here has really customized them so they look like medieval 
manuscripts or something from a futuristic video game.  (If any of that is 
possible---but in Emacs, anything is possible ...)

Bill

[1] Now I'm using https://github.com/bbatsov/solarized-emacs, with variable 
pitch turned off and Org headline resizing turned off.

Here is one approach:

I feel like I have seen some work that used ruby and python icons as
displays over #+begin_src, but I can't find it now.

I use the config John mentioned and I like it - though I use different
symbols. Here's my config if you want an example:

If you haven't already, you probably know all about it; but, for any
newcomers on the subject of Literate Programming & source code blocks, etc.

Highly recommend Knuth's CWEB book & of course NOWEB software {which is
CWEB generalized for ALL programming languages}:

https://www-cs-faculty.stanford.edu/~knuth/cweb.html

Thanks Diego, its a very interesting config example

Re: Anyone doing any fancy customizations of source blocks?

[Diego Zamboni]

Hi Brian,

Thanks for the kind words! I wrote a booklet about my setup including
other "literate config" examples, if you are interested:
https://leanpub.com/lit-config/read

I have been fascinated by the idea of literate programming since I got
a copy of The Stanford GraphBase while I was in college. I never used
CWEB directly, but I have tried noweb and other literate programming
tools over the years. However, Emacs + Org-mode + Babel is the first
toolset that I have actually been able to stick with on sustained use
:)

Best,
--Diego

There’s some work to generalize this here:

    https://github.com/integral-dw/org-menu-mode

I have not had a chance to try it myself yet.

That being said, the above approach still lives in my setup and doesn’t
bother me too much even if it is hack :)

Stay safe,
Rasmus

Thanks for this.  I used it for a while, and it looks great, but I decided I 
want to see the details on the begin_src line all the time.  I do like using the 
⎡and ⎣ character nr prettify-symbols-ali stto replace #+begin_src and 
#+end_src and will keep those.

(My apologies for weirdness in that line---the Unicode threw things off and 
I can't get it back to normal.)

I'll refer to your configuration file when I move my init files into Org.  It's 
a great example.

Hi Bill,

I'm glad you found the example useful. I've been thinking myself of also un-hiding the header arguments, which I do find useful to have visible.

Best,

This example reminded me of something that’s been puzzling me. In the
screenshot, the background color of lines that begin and end a source
block extend all the way across the screen.

When I change the faces for org block begin/end to something with a
background color, the color only extends to the end of the characters on
that line. The same is true if I change the background color of the
content of the block.

This is quite distracting. I thought “this must be the consequence of
some other mode I’m using or something” and I decided to test that. I
fired up “emacs -q” and loaded the code pointed to by the post above.
What I get is:

What’s the trick to get the background color to extend across the entire line?

In Emacs 27, add an `:extend t` property to the face. In Emacs 26 
and earlier, IIRC, you need to make sure that the newline at the 
end of the line is also fontified. (That may actually be necessary 
in Emacs 27 as well, in addition to the `:extend` property...)

Thank you! I somehow failed to connect that with my move to Emacs 27 a
while back.
