This Emacs setup aims to install automatically a minimal set of extension
|
||
packages that allows to handle my reports and presentations. The file format of
|
||
the reports is [[https://orgmode.org/][Org Mode]] plain text with [[https://www.python.org/][Python]] source code blocks and the file
|
||
format of the presentations is [[https://www.latex-project.org/][LaTeX]].
|
||
|
||
This [[info:org#Top][org]] file (more precisely the original [[info:org#Top][org]] source file of this file)
|
||
illustrates three methods in my work-flow:
|
||
1. How to tangle (or export) source blocks from [[info:org#Top][org]] files. This file contains
|
||
source blocks to produce the files =early-init.el=, =init.el=, =latexmkrc=, =org-store-link=, and =example.py= by tangling.
|
||
2. How to export [[info:org#Top][org]] files to other formats such as [[https://en.wikipedia.org/wiki/HTML][HTML]], [[https://www.latex-project.org/][LaTeX]], and [[https://en.wikipedia.org/wiki/PDF][PDF]].
|
||
3. How [[info:org#Hyperlinks][org hyperlinks (info)]] allow to link inside and outside [[info:org#Top][Org Mode]]: hover
|
||
over or click on the links to experiment.
|
||
|
||
The [[https://en.wikipedia.org/wiki/AUCTeX][AUCTeX - Aalborg University Center TeX]] extension package provides a
|
||
powerful [[https://en.wikipedia.org/wiki/Text-based_user_interface][Text-based User Interface (TUI)]] environment to edit the [[https://www.latex-project.org/][LaTeX]]
|
||
presentations.
|
||
|
||
The [[https://github.com/bdarcus/citar][citar]] extension package provides quick filtering and selecting of
|
||
bibliographic entries, and the option to run different commands on those
|
||
selections. [[https://github.com/bdarcus/citar][Citar]] requires [[info:org#Top][Org-9.5 (info)]], which is already part of Emacs-28.1.
|
||
[[https://github.com/bdarcus/citar][Citar]] exploits the enhancements of Emacs' builtin selection mechanism provided
|
||
by the extension packages [[https://github.com/minad/vertico][vertico]], [[https://github.com/oantolin/orderless][orderless]], [[https://github.com/oantolin/embark][embark]], [[https://github.com/minad/marginalia][marginalia]], and [[https://github.com/minad/consult][consult]].
|
||
The [[https://github.com/andras-simonyi/citeproc-el][citeproc]] extension package provides [[https://citationstyles.org/][CSL: citation style language]] processing
|
||
capabilities to [[https://github.com/bdarcus/citar][citar]] and [[https://orgmode.org/][Org Mode]]. [[https://github.com/citation-style-language/styles#readme][Citation style language: style repository]]
|
||
links to a curated repository of CSL styles.
|
||
|
||
The [[https://github.com/vedang/pdf-tools][pdf-tools]] extension package renders [[https://en.wikipedia.org/wiki/PDF][PDF]] file with the possibility to
|
||
annotate the file or to click on anchors in the [[https://en.wikipedia.org/wiki/PDF][PDF]] file that link back to the
|
||
original [[https://www.latex-project.org/][LaTeX]] file of the document. An example of my work-flow are the steps
|
||
to convert this [[info:org#Top][org]] file to [[https://en.wikipedia.org/wiki/PDF][PDF]] and to see the result with [[https://github.com/vedang/pdf-tools][pdf-tools]] in Emacs:
|
||
execute the commands ~pdf-tools-install~, ~org-babel-tangle~,
|
||
~org-latex-export-latex-to-latex~, and ~compile~. This sets up an infinite
|
||
[[https://www.latex-project.org/][LaTeX]] compilation loop to update and redisplay the [[https://en.wikipedia.org/wiki/PDF][PDF]] file after excution of
|
||
the ~org-latex-export-latex-to-latex~ command in this buffer.
|
||
|
||
Here follows a list of interesting Emacs configurations:
|
||
1. [[https://github.com/alhassy/emacs.d][Musa Al-hassy's configuration]] is an impressive example of producing the Emacs
|
||
initialization files and other files by tangling an [[info:org#Top][org]] file. His methodology
|
||
is impressive, as his [[https://alhassy.github.io/ElispCheatSheet/][Elisp Cheat Sheet]] and [[https://alhassy.github.io/org-special-block-extras/][org-special-block-extra package]]
|
||
show. To me, this is a configuration to admire, but his methodology is way
|
||
over my head.
|
||
2. [[https://github.com/oantolin/emacs-config][Omar Antolin Camarena's configuration]] exploits built-in packages, Omar's own
|
||
small packages, and large external packages. Omar is the author of [[https://github.com/oantolin/orderless][orderless]]
|
||
and [[https://github.com/oantolin/embark][embark]]. I have stolen his idea of using ~custom-set-variables~ instead
|
||
of the customize interface although that is [[https://www.masteringemacs.org/article/bad-emacs-advice][bad Emacs advice]] for new users.
|
||
3. [[https://gitlab.com/ambrevar/dotfiles][Pierre Neirhardt's configuration]] implements lazy loading without help of
|
||
external packages. I have stolen his approach of using lazy loading to
|
||
silently ignore the setup stanzas of uninstalled extension packages.
|
||
4. [[https://sachachua.com/dotemacs/][Sacha Chua's configuration]] is a practical example of producing the Emacs
|
||
initialization files by tangling an [[info:org#Top][org]] file. It gives me the impression
|
||
that she is a very practical person trying to achieve her goals by the most
|
||
efficient means. I have stolen her idea of using [[https://github.com/quelpa/quelpa][quelpa]] to install packages
|
||
from any source.
|
||
5. [[https://github.com/purcell/emacs.d][Steve Purcell's configuration]] is well organized, a showcase of readable code,
|
||
as well helpful commit and issue histories. See for instance the discussion
|
||
on [[https://github.com/purcell/emacs.d/issues/778][the correctness of order of company candidates in Emacs lisp mode]].

The =user-init-file= header requires =cl-lib= and customizes Emacs variables.
|

It consists of three parts in listing [[lst:1st-custom-set-variables-call]],
|
||
[[lst:2nd-custom-set-variables-call]], and [[lst:3rd-custom-set-variables-call]] in
|
||
order to limit the length of the listings for exporting to LaTeX.
|

The [[info:elisp#Quoting][quoting (info)]] and the [[info:elisp#Backquote][backquote (info)]] pages explain how to understand the
|
||
~'~ (quote), ~`~ (backquote), ~,~ (substitute) and ~@,~ (splice) in the
|

~custom-set-variables~ function calls in listing

[[lst:1st-custom-set-variables-call]], [[lst:2nd-custom-set-variables-call]], and

is the [[https://mullikine.github.io/posts/macro-tutorial/][didactic emacs-lisp macro example]].

Section [[#sec:text-faces-or-styles][text faces or styles]] tells that this setup does not use theming.

However, in order to improve visibility, it relies on:
|

1. Tweaking faces in memory after loading as in listing

|

2. Toggling between a dark and light background by means of

integration of [[https://github.com/ranger/ranger#readme][ranger]] in Emacs.
|

|
||
For instance, this setup allows to insert an =org-mode= link to an poorly
|
||
identified file containing a specific image into an =org-mode= buffer by means
|
||
of the facilities of [[info:emacs#Dired][dired (info)]] as follows:
|
||
1. Type {{{kbd(C-x d)}}} to open the directory containing the pooly identified
|
||
file with the specific image in a =dired-mode= buffer.
|
||
2. Start searching for the specific image by navigating to the name of any image
|
||
file.
|
||
3. Type {{{kbd(v)}}} to switch to view the file in an =image-mode= buffer.
|
||
4. In the =image-mode= buffer, continue searching for the specific image by
|
||
typing:
|
||
- {{{kbd(n)}}} to view the next image in the =dired-mode= buffer,
|
||
- {{{kbd(p)}}} to view the previous image in the =dired-mode= buffer, and
|
||
- {{{kbd(q)}}} to quit the =image-mode= buffer and to go back to the =dired-mode= buffer.
|
||
5. After finding the specific image, use {{{kbd(C-c l)}}} in the =image-mode=
|
||
buffer or the =dired-mode= buffer to store the =org-link=.
|
||
6. Switch to the =org-mode= buffer and use {{{kbd(C-c C-l)}}} to insert the =org-link= into the buffer.

2. Let [[https://en.wikipedia.org/wiki/Rsync][rsync]] copy marked files outside Emacs to a local or remote directory.

[[info:emacs#Package Installation][Emacs installs packages]] from archives on the internet. This setup uses three
|
||
archives:
|
||
1. The [[https://elpa.gnu.org/][GNU Emacs Lisp Package Archive]]
|
||
2. The [[https://elpa.nongnu.org/][NonGNU Emacs Lisp Package Archive]].
|
||
3. The [[https://melpa.org/#/][Milkypostman's Emacs Lisp Package Archive (MELPA)]].
|
||
In addition, the [[https://github.com/quelpa/quelpa][quelpa]] tool allows to fetch code from any source and build a
|
||
package on your computer before installation. The code in listing
|
||
[[lst:install-selected-packages]] assumes that the package system is in a *virgin*
|
||
state if the package [[https://github.com/emacscollective/no-littering][no-littering]] is not present:
|
||
1. It installs and loads [[https://github.com/emacscollective/no-littering][no-littering]] after ensuring refreshing of the
|
||
contents of available packages.
|
||
2. It ensures installation of [[https://github.com/quelpa/quelpa][quelpa]] before ensuring installation of [[https://github.com/sheijk/org-menu#readme][org-menu]].
|
||
3. It calls src_emacs-lisp{(package-install-selected-packages)} to check the
|
||
installation status of all packages in
|
||
src_emacs-lisp{package-selected-packages} and to install the missing packages
|
||
after the user has agreed to its prompt.
|
||
4. It defines a function to ensure the installation of packages in other source
|
||
blocks. This allows skipping installation in sections with a =:noexport:=
|
||
tag by disallowing tangling.
|
||
In case of normal Emacs usage, src_emacs-lisp{(package-list-packages)} refreshes
|

the contents of packages and allows to update packages to the latest version.

The next block contains an userscript that sends a [[info:org#The store-link protocol][store-link org-protocol]]
|
||
message with the url and the title from [[https://qutebrowser.org][qutebrowser]] to =emacsclient=. The
|
||
function =urlencode= translates the url and the title for the message. The
|
||
[[info:python#Examples<22>][Python urllib examples]] show how to use =urlencode=. The final =execvp= call
|
||
deals with a [[https://qutebrowser.org][qutebrowser]] userscript requirement: the =emacsclient= process must
|
||
get the PID of the userscript that must kill itself after the take-over.
|
||
Termination of the =emacsclient= process hands control back to [[https://qutebrowser.org][qutebrowser]].
|
||
|
||
On a [[https://en.wikipedia.org/wiki/POSIX][POSIX]] system, you can run the userscript from [[https://qutebrowser.org][qutebrowser]] or from a
|
||
terminal to see whether it works. In case you try to run it from Emacs, Emacs
|
||
may hang or die.

|

[[info:vertico#Top][Vertico (info)]] provides a performant and minimalistic vertical completion UI
|
||
based on the default completion system and behaves therefore correctly under all
|
||
circumstances. [[https://cestlaz.github.io/post/using-emacs-80-vertico/][Using Vertico, Marginalia, Consult, and Embark]] links to a video
|
||
demonstration. Vertico integrates well with fully supported complementary
|
||
packages to enrich the completion UI:
|
||
1. [[info:orderless#Top][Orderless (info)]] for an advanced completion style,
|
||
2. [[info:embark#Top][Embark (info)]] for minibuffer actions with context menus,
|
||
3. [[info:marginalia#Top][Marginalia (info)]] for rich annotations in the minibuffer, and
|
||
4. [[info:consult#Top][Consult (info)]] for useful search and navigation commands,
|
||
where the order is that of [[https://github.com/bdarcus/citar#installation][enhancing citar's experience]] and the configuration
|
||
steps below.
|
||
|
||
Finally, [[https://company-mode.github.io/][company: a modular complete-anything framework for Emacs]] provides
|
||
completion in any buffer and [[#sec:minibuffer-history-completion][minibuffer-history-completion]] provides completion
|
||
on previous input in the minibuffer.

Loading =tex.el= immediately instead of lazily ensures proper initialization of
|
||
[[https://en.wikipedia.org/wiki/AUCTeX][AUCTeX]]. For instance, the ~TeX-master~ safe local variable in the =tex.el=
|
||
elisp library file has no autoload cookie. Without prior loading of =tex.el=,
|
||
Emacs will complain that ~TeX-master~ is no safe local variable in case it reads
|
||
a LaTeX file that sets ~TeX-master~. Listing [[lst:require-auctex]] initializes
|
||
[[https://en.wikipedia.org/wiki/AUCTeX][AUCTeX]] properly for LuaTeX or LuaLaTeX. In case the output of =LuaLaTeX= has
|
||
missing fonts, listing [[lst:update-lualatex-opentype-font-name-database]] defines a
|
||
function to update the =OpenType Font= name database for =LuaLaTeX=. Finally,
|

out of the box, [[https://en.wikipedia.org/wiki/AUCTeX][AUCTeX]] does not indent text between square brackets. The code

in listing [[lst:configure-auctex]] corrects this by advising to override

2. View an electronic copy of an [[https://orgmode.org/][Org-mode]] cite link:
|
||
1. Move point to the [[https://orgmode.org/][Org-mode]] cite link.
|
||
2. Type {{{kbd(C-:)}}} or {{{kbd(M-x embark-dwim)}}}.

There are at least two ways (new and old) to edit the LateX preamble
|
||
=latex_header= and =latex-extra_header= export options easily in LaTeX source or
|
||
export blocks. This [[info:org#Top][Org (info)]] file uses the new way, but keeps the old way for
|
||
backwards compatibility.
|
||
|
||
The new way -- exploiting an idea of [[https://www.matem.unam.mx/~omar/][Omar Antolin Camarena]] -- is to code new
|
||
[[info:org#Editing Source Code][<LANGUAGE>-modes]] allowing to edit in LaTeX mode and to export to LaTeX code with
|
||
[[info:org#LaTeX specific export settings][correct LaTeX preamble export setting prefixes]]. Here, are links to three posts
|
||
exposing his idea:
|
||
1. [[https://www.reddit.com/r/orgmode/comments/7u2n0h/tip_for_defining_latex_macros_for_use_in_both/][Export LaTeX macros to LaTeX and HTML/MathJax preambles (reddit)]],
|
||
2. [[https://www.reddit.com/r/orgmode/comments/5bi6ku/tip_for_exporting_javascript_source_block_to/][Export JavaScript source blocks to script tags in HTML (reddit)]],
|
||
3. [[https://emacs.stackexchange.com/questions/28301/export-javascript-source-block-to-script-tag-in-html-when-exporting-org-file-to][Export JavaScript source blocks to script tags in HTML (SX)]].
|
||
Listing [[lst:emacs-lisp-setup-latex-header]] implements this way by means of two
|
||
new [[info:org#Editing Source Code][<LANGUAGE>-modes]]: =latex-header= and =latex-extra-header=.
|
||

The old way is to use a special export attribute as in the function
|
||
=org-latex-header-blocks-filter= in [[https://git.sr.ht/~bzg/org-contrib/tree/master/item/lisp/ox-extra.el][ox-extra.el]]. Apparently, nobody is using
|
||
this broken function (broken, since it relies on support only in org-mode before
|
||
=2014-11-11=). Listing [[lst:org-latex-header-blocks-filter]] proposes a fix for
|
||
=org-latex-header-blocks-filter=.

This file uses the new way, while keeping the old way for backwards
|
||
compatibility, because the new way feels less hackish than the old way. A
|
||
practical difference is that new way source blocks (contrary to old way export
|
||
blocks) do not work in [[info:org#Export Settings][#+SETUPFILE: <FILE>]], but only in [[info:org#Export Settings][#+INCLUDE: <FILE>]] files.

Two tools to grok how [[https://orgmode.org/worg/dev/org-element-api.html][Org mode parsing]] works are the [[https://orgmode.org/worg/dev/org-syntax-edited.html][Org Syntax]] specification
|
||
and the [[http://xahlee.info/emacs/emacs/elisp_parse_org_mode.html][Org mode parser tutorial]]. The [[https://orgmode.org/worg/dev/org-element-api.html][Org element parsing API]] boils down to three
|
||
functions:
|
||
1. The function [[https://orgmode.org/worg/dev/org-element-api.html#global][~org-element-parse-buffer~]] implements a fully recursive buffer
|
||
parser that returns an abstract syntax tree.
|
||
2. The functions [[https://orgmode.org/worg/dev/org-element-api.html#local][~org-element-at-point~ and ~org-element-context~]] return
|
||
information on the document structure around point either at the element
|
||
level or at the object level in case of ~org-element-context~.
|
||
Listing [[lst:grok-org-element-tree]] improves the [[http://xahlee.info/emacs/emacs/elisp_parse_org_mode.html][Org mode parser tutorial]] by
|
||
defining interactive wrappers that pretty print the results of those
|
||
non-interactive =org-element= functions to an =Emacs-lisp= buffer.

|

1. [[https://github.com/joaotavora/eglot][Eglot - Emacs polyGLOT: an Emacs LSP client that stays out of your way]]. The

maintainer also contributes to Emacs itself and has a deep understanding of

into [[https://sheer.tj/the_way_of_emacs.html][the Way of Emacs]] as this discussion on [[https://github.com/joaotavora/eglot/issues/523][org-mode source code blocks]]

shows.
|
||
2. [[https://github.com/pythonic-emacs/anaconda-mode][Anaconda - code navigation, documentation lookup, and completion for Python]].
|
||
In my opinion, [[https://github.com/joaotavora/eglot][eglot]] has more potential than [[https://github.com/pythonic-emacs/anaconda-mode][anaconda]], but [[https://github.com/pythonic-emacs/anaconda-mode][anaconda]] is

compatible with [[info:org#Editing Source Code][source code block editing]] while [[https://github.com/joaotavora/eglot][eglot]] is not.

Listing [[lst:configure-python]] tells the Python shell to disregard its environment

variables (in particular =PYTHONSTARTUPFILE=). The [[https://github.com/pythonic-emacs/pythonic#readme][pythonic]] and [[https://github.com/jorgenschaefer/pyvenv#readme][pyvenv]] packages
|
||
provide support to handle Python virtual environments within Emacs. The [[https://github.com/pyenv/pyenv][pyenv]]

||
package provides support to work with [[https://github.com/pyenv/pyenv#readme][pyenv]] (eventually with [[https://github.com/pyenv/pyenv-virtualenv#readme][pyenv-virtualenv]])
|
||
to select between different python versions (eventually each with different
|
||
environments). In the end, all those packages do is to set
|
||
=python-shell-virtualenv-root= (in case of [[https://github.com/pyenv/pyenv#readme][pyenv]] and [[https://github.com/pythonic-emacs/pythonic#readme][pythonic]]) and tweak the

environment variables and restart the relevant Python child processes (in case

[[https://jedi.readthedocs.io/en/latest/][Jedi]] provides grammar checking and completion candidates to [[https://github.com/python-lsp/python-lsp-server][python-lsp-server]].
|
||
Only [[https://jedi.readthedocs.io/en/latest/docs/changelog.html][jedi-0.18.1]] works with for instance [[https://numpy.org/][numpy-1.22.0]] in the sense that it does
|
||
not choke on universal functions provided that [[https://jedi.readthedocs.io/en/latest/][jedi]] does not parse but imports
|
||
[[https://numpy.org/][numpy-1.22.0]] (see [[https://github.com/davidhalter/jedi/issues/1744][jedi issue #1744]], [[https://github.com/davidhalter/jedi/issues/1745][#1745]], and [[https://github.com/davidhalter/jedi/issues/1746][#1746]]). Since the universal
|
||
functions are neither builtin methods nor data instances but a kind of "callable
|
||
instances", the [[https://docs.python.org/3/library/inspect.html][Python inspect]] module also fails to handle the universal
|
||
functions properly.

the information to [[https://github.com/python-lsp/python-lsp-server][python-lsp-server]] allowing it to handle universal functions.

|

|

Structural editing keeps character pairs (for instance parentheses, curly and
|
||
square brackets as well as single and double quotes) balanced to leave code (for
|
||
instance Lisp and Python) and text (for instance LaTeX and Org) structure
|
||
intact. I use [[https://github.com/Fuco1/smartparens][smartparens]] which offers a normal mode (=smartparens-mode=) and a
|
||
a strict mode (=smartparens-strict-mode=). Although both modes insert character
|
||
pairs, the normal mode allows to delete one of the paired characters easily
|
||
while the strict mode does not. Therefore, the strict mode is more for code
|
||
editing since it never breaks programming language rules and the normal mode is
|
||
more for text editing where structure is a matter of convention instead of
|
||
programming language rules.
|
||
|
||
For instance, the strict mode in Python allows to delete entire lists, tuples,
|
||
or the arguments after the cursor (what Emacs calls =point=) in a function call
|
||
without breaking the character pair balance. In order to repair a broken
|
||
character pair balance, insert a single character by prefixing it with "C-q"
|
||
bound to =quoted-insert=.
|
||
|
||
The [[https://smartparens.readthedocs.io/en/latest/index.html][smartparens documentation]] targets experienced Emacs users. The
|
||
following links show how to put the documentation to practical use:
|
||
1. [[https://gist.github.com/oantolin][Omar Antolin's gist "my-smartparens-config.el"]] is the first place to look for
|
||
how to tweak [[https://github.com/Fuco1/smartparens][smartparens]]. However, the gist may be partially obsolete, since
|
||
it is not part of his current [[https://github.com/oantolin/emacs-config][Emacs configuration]].
|
||
2. [[https://lists.gnu.org/archive/html/help-gnu-emacs/2014-07/msg00135.html][How to enable smartparens in the minibuffer after eval-expression]] explains
|
||
how the machinery after the first and after later usages of =eval-expression=
|
||
differ and discusses options how to handle those differences.
|
||
Listing [[lst:configure-smartparens]] aims to configure [[https://github.com/Fuco1/smartparens][smartparens]] for Elisp,
|
||
LaTeX, Org, and Python.
|
||
|
||
Despite the provocative post [[https://andreyorst.gitlab.io/posts/2022-02-20-what-if-structural-editing-was-a-mistake/]["What if structural editing was a mistake?"]],
|
||
[[https://github.com/Fuco1/smartparens][smartparens]] is one of my favorite packages. In particular, [[https://github.com/Fuco1/smartparens][smartparens]] handles
|
||
matching pairs in Org-mode files with export and source blocks for multiple
|
||
formats and languages correctly. Therefore, [[https://smartparens.readthedocs.io/en/latest/index.html?highlight=show-smartparens-mode#getting-started][show-smartparens-mode]] highlights
|
||
matching pairs immediately in front or after point in such files correctly,
|
||
contrary to for instance [[https://github.com/Fanael/rainbow-delimiters#readme][rainbow-delimiters]].

This setup does not configure [[info:emacs#Custom Themes][custom themes (info)]] in order to prevent endless

fonts properly. It boils down to two rules:
|

1. The height of the default face must be an integer number to make the height a

physical quantity.
|

2. The heights of all other faces must be real numbers to scale those heights

with respect to the height of the face (those heights default to 1.0 for no
|
||
scaling).
|
||
The code in listing [[lst:configure-face-attributes]] source implements those rules.

In case of proper initialization of all face heigths, font scaling is easy as

listing [[lst:set-default-face-height]] shows.
