After its invokation, Emacs will install a minimal set of packages. Now, you
have the option to install all optional packages using the command
=my-install-optional-packages= , but you can do this any time, or you can install
any package using the command =package-install= whenever you like. Quit Emacs
and invoke Emacs again.

* Introduction
:PROPERTIES:
:CUSTOM_ID: sec:introduction
:END:
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 my work-flow by showing:
2021-11-30 09:35:15 +01:00
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.
2021-11-29 13:14:56 +01:00
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 ]].
The [[https://github.com/vedang/pdf-tools ][pdf-tools ]] extension package renders [[https://en.wikipedia.org/wiki/PDF ][PDF ]] file with the possibility to
2021-11-30 09:35:15 +01:00
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
2021-11-29 13:14:56 +01:00
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.

[[info:emacs#Top ][Emacs (info) ]]
2021-11-29 13:14:56 +01:00
Here follows a list of interesting Emacs configurations:
1. [[https://github.com/oantolin/emacs-config ][Omar Antolín Camarena's configuration ]]
2. [[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.
3. [[https://sachachua.com/dotemacs/ ][Sacha Chua's configuration ]] is an 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.
4. [[https://github.com/purcell/emacs.d ][Steve Purcell's configuration ]] is well organized and a show-case of readable
[[info:elisp#Top ][Emacs lisp (info) ]] code. I have stolen his idea of versioning the
~package-user-dir~ variable to prevent clashes between the byte-compiler
output of different Emacs versions.

* Package bootstrapping
:PROPERTIES:
:CUSTOM_ID: sec:package-bootstrapping
:END:
[[info:emacs#Package Installation ][Emacs installs packages ]] from archives on the internet.
This setup uses three archives in two decreasing levels of priority:
1. The [[https://elpa.gnu.org/ ][GNU Emacs Lisp Package Archive ]] or the [[https://elpa.nongnu.org/ ][NonGNU Emacs Lisp Package Archive ]].
3. The [[https://melpa.org/#/ ][MELPA - Milkypostman’ ]].
Finally, the [[https://github.com/quelpa/quelpa ][quelpa ]] tool allows to fetch code from any source and build a
package on your computer before installation. It allows to install a package
from [[https://melpa.org/#/ ][MELPA ]] instead of [[https://elpa.gnu.org/ ][GNU ELPA ]] or [[https://elpa.nongnu.org/ ][NonGNU ELPA ]], breaking the priority order.
The output of the byte-compiler may change with each new Emacs release.
Therefore, in order to prevent collisions between different Emacs versions, the
package-user-directory has a suffix containing the major- and minor-version
numbers of Emacs.
The order of the next 1nd, 2nd, and 3rd package-bootstrapping blocks matters
because each of those blocks prepares Emacs for the next block.
If present, the package [[https://github.com/emacscollective/no-littering ][no-littering ]] helps to keep =~/.emacs.d= clean.
The code assumes that the package system is in a *virgin* state in case the
package [[https://github.com/emacscollective/no-littering ][no-littering ]] is not present. Refreshing the contents of available
packages at least once is a requirement in order to be able to install and load
any packages, hence also [[https://github.com/emacscollective/no-littering ][no-littering ]].
You have to refresh the list of available packages yourself before updating
the installed packages.
Finally, ~my-install-packages~ ensures installation of all packages in a list of
packages.

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.

** PDF files
The [[https://github.com/vedang/pdf-tools ][pdf-tools ]] package exploits the [[https://github.com/freedesktop/poppler ][poppler ]] library to render and to let you
annotate [[https://en.wikipedia.org/wiki/PDF ][PDF ]] files. It also exploits the [[https://wiki.contextgarden.net/SyncTeX ][SyncTeX ]] library to link anchors in [[https://en.wikipedia.org/wiki/PDF ][PDF ]]
files produced with LaTeX to the original LaTeX sources.
In order to use [[https://github.com/vedang/pdf-tools ][pdf-tools ]], you have to type =M-x pdf-tools-install= after
installation of [[https://github.com/vedang/pdf-tools ][pdf-tools ]] from [[https://melpa.org/ ][MELPA ]] or after each update of [[https://github.com/freedesktop/poppler ][poppler ]] to build
or rebuild the =epdfinfo= executable that serves the [[https://en.wikipedia.org/wiki/PDF ][PDF ]] files to Emacs.

* Writing
** LaTeX
Loading =tex.el= immediately instead of lazily ensures proper initialization of
the [[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~ .
Out of the box, [[https://en.wikipedia.org/wiki/AUCTeX ][AUCTeX ]] does not indent text between square brackets. The code
below corrects this by advising to override ~TeX-brace-count-line~ with
~my-TeX-brace-count-line~ .

** Python coding
Here, the focus is on three ways to extend Emacs's built-in ~python-mode~ out of
the options listed on the [[https://www.emacswiki.org/emacs/PythonProgrammingInEmacs ][Python Programming in Emacs ]] wiki page:
1. [[https://elpy.readthedocs.io/en/latest/ ][Elpy ]] is an opinionated Python integrated development environment with its own
Python server and its own server protocol. Its main disadvantages are:
1. It requires a high number of Elisp and Python packages.
2. It imposes its way making it hard to do otherwise for beginners.
3. It requires a new maintainer, because the current maintainer has no time
anymore for adding new features or squashing hard bugs.
Its main advantages are:
1. Its usability out of the box.
2. Its documentation quality.
3. Its compatibility with the Org source block editing mode.
2. [[https://emacs-lsp.github.io/lsp-mode/ ][LSP Mode - Language Server Protocol support for Emacs ]] with its [[https://emacs-lsp.github.io/lsp-ui/ ][LSP-UI ]] user
interface extensions. According to [[https://github.com/emacs-lsp/lsp-mode/blob/master/docs/manual-language-docs/lsp-org.md][Literate programming using LSP and
org-mode(alpha)]], this package tries to be compatible with the Org source
block editing mode, but it is not ready for daily usage.
3. [[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
[[https://sheer.tj/the_way_of_emacs.html ][the Way of Emacs ]]. He refuses to add new features without seeing how they fit
into [[https://sheer.tj/the_way_of_emacs.html ][the Way of Emacs ]] as this discussion at [[https://github.com/joaotavora/eglot/issues/523][Eglot github issue: org-mode
source code blocks]] shows.
