Subject: Re: [PATCH] (v2) New LaTeX code export option: engraved

Hi Daniel & co.,
I have a new set of patches (attached), which make use of a major new feature in
engrave-faces v0.3: engraved themes.
Now, the theme used for source blocks can be set by the document keyword
`#+latex_engraved_theme: THEME-NAME'. Furthermore, the theme can be customised on
a per-code-block basis with `#+attr_latex: :engraved-theme THEME-NAME'.
If you try this out, make sure you have the most recent commit of engrave-faces
(531ea687e, soon to be released in v0.3.1).
I’ve also fixed the “Bug: Percentage in caption (even escaped) does not work in
LaTeX export” that Max raised
(<https://list.orgmode.org/YT2PR01MB45101E27DC6251D8F8B7B366F6EC9@YT2PR01MB4510.CANPRD01.PROD.OUTLOOK.COM>).

Glad to hear you’ve been able to have a look over the patches. With the feedback
I’ve received here so far, if no issues come up in the next few days I’m
inclined to merge this, add documentation, and see what feedback pops up.

Sure. The result should be visually identical to what you’d see in elisp/python
buffer, but possibly with a different theme.
Say you wanted to use a tweaked version of the default theme, this could be
accomplished like so:
┌────
│ (setq default2 (alist-get 'default engrave-faces-themes))
│ ;; Make comments hot pink
│ (plist-put (alist-get 'font-lock-comment-face default2) :foreground "#ff69b4")
│ ;; Any other customisations...
│ (add-to-list 'engrave-faces-themes (cons 'default2 default2))
└────
Then in the Org file you can use the “default2” engraved theme with
`#+latex_engraved_theme: default2'.
Let me know if there are any other examples you’d like to see.

👍 see my earlier comment on merging.
All the best,
Timothy

Subject: [PATCH 01/10] ox-latex: Refactor `org-latex-src-block'
* lisp/ox-latex.el (org-latex-src-block): Extract the per-format logic
from `org-latex-src-block' into new dedicated functions:
+ `org-latex-src-block--verbatim'
+ `org-latex-src-block--custom'
+ `org-latex-src-block--minted'
+ `org-latex-src-block--listings'
This makes `org-latex-src-block' much less monolithic, taking it from
175 lines to 30, and I find also makes it easier to understand.

Subject: [PATCH 03/10] ox-latex: More versitile option construction
* lisp/ox-latex.el (org-latex--make-option-string): Support a custom
option seperator string.
(org-latex--make-option-string, org-latex-minted-options,
org-latex-listings-options): The first line of the docstrings for
`org-latex-minted-options` and `org-latex-listings-options` describe the
variables as "association lists", yet `org-latex--make-option-string`
does not handle association lists and an example of two-value lists is
provided. To make the behaviour match the docstring,
`org-latex--make-option-string` is modified to work with either a list
two-value lists or an association list, and the examples in
`org-latex-minted-options` and `org-latex-listings-options` updated
accordingly.

Subject: [PATCH 04/10] ox-latex: Introduce "engraved" code highlighting
* lisp/ox-latex.el (org-latex-src-block, org-latex-src-block--engraved,
org-latex-inline-src-block, org-latex-inline-src-block--engraved,
org-latex-src--engrave-code, org-latex-template, org-latex-listings):
Make use of the engraved-faces package (available on ELPA) to provide an
alternative LaTeX code highlighting backend which functions similarly to
htmlize.el for HTML exports.
(org-latex-engraved-preamble, org-latex-engraved-options): Introduce
variables to construct the preamble for engraved code blocks.
* lisp/ox-beamer.el (org-beamer-template): Modify to add engrave-faces
preamble when applicable.

Subject: [PATCH 07/10] ox-latex: Replace `org-latex-listings'
* lisp/ox-latex.el (org-latex-src-block, org-latex-keyword,
org-latex-inline-src-block, org-latex-template,
org-latex--caption/label-string, org-latex-engraved-preamble,
org-latex-listings): Replace `org-latex-listings' with
`org-latex-src-block-backend', which now can be set to listings/verbatim
and no longer advertises t/nil as valid values.
* lisp/ox-beamer.el (org-beamer-template): Update in the same manner as
`org-latex-template'.
* lisp/org-compat.el: Make `org-latex-listings' an obsolete alias for
`org-latex-src-block-backend'.
* testing/lisp/test-ox.el: Replace `org-latex-listings' reference with
`org-latex-src-block-backend'.
* doc/org-manual.org (Footnotes, LaTeX specific properties, Literal
Examples): Replace references to `org-latex-listings' with
`org-latex-src-block-backend'.
* etc/ORG-NEWS: Add a news entry noting this change.
The variable `org-latex-listings' originally indicated whether source
blocks should use the listings LaTeX package, or not. This usage has
evolved over the years, and now it sets one of four different
fontification backends. This renaming should make the variable name a
bit less misleading.

Subject: [PATCH 08/10] ox-latex: Support setting the engraved theme
* lisp/ox-latex.el (org-latex-generate-engraved-preamble,
org-latex-engraved-theme): Introduce the new export keyword
LATEX_ENGRAVED_THEME with default value given by
`org-latex-engraved-theme'. This is used to set the engraved theme used
in org-latex-engraved-theme.
This bumps the minimum required version of engrave-faces from v0.2 to
v0.3.

Subject: [PATCH 09/10] ox-latex: Support setting engraved theme per-block
* lisp/ox-latex.el (org-latex-src-block--engraved,
org-latex-src--engrave-code, org-latex-inline-src-block--engraved,
org-latex-generate-engraved-preamble): Allow for the engraved theme used
to be set on a per-src-block basis with #+attr_latex: :engraved-theme
THEME. Extra setup code is now generated in
`org-latex-generate-engraved-preamble'. To facilitate the application
of themes to src blocks, `org-latex-src--engrave-code' now takes on a
larger portion of the transcoding work.

Subject: [PATCH 10/10] ox-latex: Fix %-captions in minted/engraved code
* lisp/ox-latex.el (org-latex-src-block--engraved,
org-latex-src-block--minted): Refactor float-env to be clearer, and
switch from `format' to `concat' to fix the bug where %-chars in
captions are interpreted as a format specifier.
