This setup requires at least Emacs-29.0.91. Backup the =user-emacs-directory=
|
||
(defaults often to =~/.emacs.d= on =Linux=, =Unix=, or =Darwin=) and execute the
|
||
commands in listing [[lst:prepare-user-emacs-directory-with-https][prepare the =user-emacs-directory= without =ssh= access]] or
|
||
in listing [[lst:prepare-user-emacs-directory-with-ssh][prepare the =user-emacs-directory= with =ssh= access]]. After invoking
|
||
Emacs interactively (in interactive mode, neither in batch mode, nor in server
|
||
mode), Emacs will ask you to install a selected set of packages. Quit Emacs and
|
||
invoke Emacs again.

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]] exploits the extension packages [[https://github.com/minad/vertico][Vertico]], [[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]]. A curated repository
|
||
of CSL styles is the [[https://github.com/citation-style-language/styles#readme][citation style language repository]].
|
||
|
||
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]]. My use =setopt= to set Emacs options instead of the customize
|
||
interface comes from his idea of using =custom-set-variables= 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.
|
||
5. [[https://github.com/purcell/emacs.d][Steve Purcell's configuration]] is well organized and a showcase of readable
|
||
code. Its commit and issue histories are also helpful: see for instance the
|
||
discussion [[https://github.com/purcell/emacs.d/issues/778][The order of company candidates is incorrect in Emacs lisp mode]].
|
||
|
||
Here follows a list of links on how to use Emacs and Elisp:
|
||
1. [[https://www.masteringemacs.org/][Mastering Emacs]] is a link to a blog with many interesting posts that promotes
|
||
a book on how to become a proficient Emacs user.
|
||
2. [[https://www2.lib.uchicago.edu/keith/emacs/][Use GNU Emacs: The Plain Text Computing Environment]] explains the fundamentals
|
||
of the Emacs abstractions before showing how to exploit those abstractions
|
||
interactively. It targets a similar audience as the [[https://www.masteringemacs.org/][Mastering Emacs]] book.
|
||
3. [[https://www.youtube.com/watch?v=lkIicfzPBys][A guided tour of Emacs]] is a link to a video tour pointing how [[info:emacs#Buffers][buffers (info)]],
|
||
[[info:emacs#Dired][dired (info)]], [[info:emacs#Help][documentation (info)]], [[info:elisp#Top][elisp (info)]], [[info:elisp#Debugging][elisp debugging (info)]],
|
||
[[info:eshell#Top][eshell (info)]], and [[info:emacs#Keyboard Macros][keyboard macros (info)]] turn Emacs in an powerful coding
|
||
and editing environment.
|
||
4. [[https://www.youtube.com/watch?v=6ZWp05OW1c0][Emergency Emacs]] is a link to a video on fundamental editing features and
|
||
principles with focus on [[info:ediff#Top][ediff (info)]], [[info:emacs#Undo][undo (info)]], [[info:emacs#Moving Point][moving point (info)]],
|
||
[[info:emacs#Erasing][erasing (info)]], and [[info:emacs#Dynamic Abbrevs][dynamic abbreviations (info)]].
|
||
5. [[https://endlessparentheses.com/][Endless Parentheses]] is a blog with many mindblowing code snippets.
|
||
6. [[https://www.murilopereira.com/how-to-open-a-file-in-emacs/][How to open a file in Emacs]] looks into [[info:elisp#Top][elisp (info)]] and
|
||
[[info:elisp#Debugging][elisp debugging (info)]] and then compares Emacs, [[https://www.vim.org/][Vim]],
|
||
[[https://neovim.io/][Neovim]], and [[https://code.visualstudio.com/][Visual Studio Code]] with respect to values and technology.
|
||
7. [[https://protesilaos.com/codelog/2022-01-31-learning-emacs/][Learning Emacs and Elisp]] is a link to a video tutorial with a transcript on
|
||
the best approach to learn Emacs and Elisp.

[[info:emacs#Package Installation][Emacs installs packages]] from archives on the internet. This setup uses five

archives:
|

1. The [[https://elpa.gnu.org/][GNU Emacs Lisp Package Archive]].
|
||
2. The [[https://elpa.gnu.org/devel/index.html][Development Emacs Lisp Package Archive]].
|
||
3. The [[https://elpa.nongnu.org/][NonGNU Emacs Lisp Package Archive]].
|

4. The [[https://melpa.org/#/][Milkypostman's Emacs Lisp Package Archive (MELPA)]] with its official
|
||
[[https://www.mirrorservice.org/sites/melpa.org/packages/][mirror]] in case [[https://downforeveryoneorjustme.com/melpa.org][is Melpa.org down?]] tells [[https://melpa.org/#/][MELPA]] is down for everyone.
|
||
5. The [[https://stable.melpa.org/#/getting-started][Stable Milkypostman's Emacs Lisp Package Archive]].
|
||
|
||
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 upgrades the build in Org package.
|
||
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.

:END:
|
||
|
||
This setup does not use [[info:emacs#Custom Themes][custom themes (info)]] to avoid endless tweaking, but it
|
||
does a minimal setup of fonts and faces. See the [[https://protesilaos.com/codelog/2020-09-05-emacs-note-mixed-font-heights/][note on mixed font heights in
|
||
Emacs]] for how to setup 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.
|
||
Listing [[lst:set-default-face-height]] shows that font scaling is easy in case of
|
||
proper initialization of all face heigths. Listing
|
||
[[lst:fix-gtk-color-for-invert-default-face]], [[lst:shadow-org-font-lock-faces]], and
|
||
[[lst:shadow-org-font-lock-faces]] show a few tweaks to improve visibility without
|
||
theming:
|
||
1. Fixing the =gtk= background color of the already loaded =region= face.
|
||
2. Toggling between a dark and light background by means of
|
||
src_emacs-lisp{(invert-default-face)}.
|
||
3. Shadowing the definition of faces before loading. The last item in the page
|
||
on [[https://orgmode.org/worg/org-contrib/babel/examples/fontify-src-code-blocks.html#org5c4406f][fontifying Org mode source code blocks]] describes this method.

[[info:emacs#Dired][Dired (info)]] and the [[https://github.com/ranger/ranger#readme][ranger]] file manager offer similar capabilities for copying,
|
||
deleting, opening, renaming, and viewing files and directories, but the
|
||
integration of [[info:emacs#Dired][dired (info)]] in Emacs is obviously much better than the
|
||
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.

Listing [[lst:extra-dired-key-bindings]] adds new key bindings to =dired-mode-map= to:
|
||
1. Open files with the [[https://en.wikipedia.org/wiki/Eww_(web_browser)][Emacs Web Wowser]] inside Emacs.
|
||
2. Let [[https://en.wikipedia.org/wiki/Rsync][rsync]] copy marked files outside Emacs to a local or remote directory.
|
||
The link [[https://truongtx.me/tmtxt-dired-async.html][asynchoronous execution library for Emacs Dired]] is the original source
|
||
for the idea of using [[https://en.wikipedia.org/wiki/Rsync][rsync]] and the blog articles [[https://oremacs.com/2016/02/24/dired-rsync/][using rsync in dired]] and
|

[[https://vxlabs.com/2018/03/30/asynchronous-rsync-with-emacs-dired-and-tramp/][asynchronous rsync with Emacs, dired and tramp]] are vivid recommendations written

[[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:embark#Top][Embark (info)]] for minibuffer actions with context menus,
|
||
2. [[info:marginalia#Top][Marginalia (info)]] for rich annotations in the minibuffer, and
|
||
3. [[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

Loading =tex.el= immediately instead of lazily ensures proper initialization of
|
||
[[https://en.wikipedia.org/wiki/AUCTeX][AUCTeX]]. In particular, 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~. The list below summarizes the main [[https://en.wikipedia.org/wiki/AUCTeX][AUCTeX]]
|
||
configuration objectives:
|

1. Listing [[lst:set-tex-options]] ensures installation of [[https://en.wikipedia.org/wiki/AUCTeX][AUCTeX]] and initializes
|
||
[[https://en.wikipedia.org/wiki/AUCTeX][AUCTeX]] properly for =LuaTeX= or =LuaLaTeX=.
|

2. Listing [[lst:set-tex-options]] also enables [[https://git.savannah.gnu.org/cgit/auctex.git/patch/?id=f464242eab092e610dda6b654e6fd197ef649d3eAA][indenting between square brackets]]
|
||
which is a recent feature.
|
||
3. Listing [[lst:update-lualatex-opentype-font-name-database]] defines a function to
|
||
update the =OpenType Font= name database for =LuaLaTeX= when the output of =LuaLaTeX= shows missing fonts.
|
||
4. Listing [[lst:set-bibtex-options]] configures the Emacs =bibtex= library to use the
|
||
LaTeX =BiBTeX= dialect for backwards compatibility.
|
||
5. Listing [[lst:set-font-latex-options]] disables font scaling of section titles.
|
||
6. Listing [[lst:set-latex-options]] configures =latex= for a full featured =LaTeX-section-command=.

I have split the initial [[https://orgmode.org/][Org-mode]] setup over several listings. Here, follows a
|
||
list detailing and motivating each listing:
|
||
1. Listing [[lst:set-org-options]] handles basic [[https://orgmode.org/][Org-mode]] options.
|
||
2. Listing [[lst:setup-org-babel]] handles basic [[https://orgmode.org/][Org-mode]] options specific to
|
||
[[info:org#Working with Source Code][work with source code (info)]].
|
||
3. Listing [[lst:set-org-link-options]] handles [[https://orgmode.org/][Org-mode]] options specific to
|
||
[[info:org#Hyperlinks][hyperlinks (info)]].
|
||
4. Listing [[lst:setup-org-mode-map]] extends the =org-mode-map= with useful
|
||
key-bindings.
|
||
5. Listing [[lst:setup-org-src]] facilitates [[info:org#Editing Source Code][editing Python source code blocks]],
|
||
and it provides a function to remove the indentation of all =org-src-mode=
|
||
blocks without =-i= switch.
|
||
6. Listing [[lst:setup-ob-python]] allows to pretty-print Python session source
|
||
block values with [[https://github.com/psf/black#readme][black]] instead of [[https://docs.python.org/3/library/pprint.html][pprint]].
|
||
7. Listing [[lst:set-org-export-options]] selects the =non-intrusive= expert user
|
||
interface for export dispatching.
|
||
8. Listing [[lst:setup-org-for-lualatex-export]] and
|
||
[[lst:set-ox-latex-options-for-lualatex-export]] configure [[https://orgmode.org/][Org-mode]] to generate
|
||
output for the LuaLaTeX compiler.
|
||
9. Listing [[lst:setup-org-latex-classes]] defines [[info:org#LaTeXspecificexportsettings][org-latex-classes (info)]] for
|
||
backward compatibility. See table [[tab:org-latex-class-tag-placeholder]] and
|
||
type {{{kbd(C-hv org-latex-classes)}}} for an explanation of the code in
|
||
listing [[lst:setup-org-latex-classes]].

This package has a front-end that processes fontified buffers and pipes its
|
||
output into one of three back-ends for export to LaTeX, HTML and text with ANSI
|
||
escape codes. It is an alternative to =minted= in case of LaTeX export or to
|
||
=htmlized= in case of HTML export.
|
||
|
||
The listings below work around one issue with spacing in the =pdf= output
|
||
resulting from use of the =engraved= source block back-end during =LaTeX=
|
||
export. They increase the quality of the export results of this [[file:README.org][README.org]] and
|
||
the user-friendliness of this facility to a level acceptable for my workflow:
|
||
1. The default Org export configuration for engraving listings produces =pdf=
|
||
output with a non-equidistant interline spacing in floating listings (those
|
||
with captions) and equidistant interline spacing in non-floating =tcolorbox=
|
||
environments (those without captions). I have traced the non-equidistant
|
||
interline spacing back to the =breakable= option of =Code= environments
|
||
inside =listing= environments. However, =tcolorbox= requires =breakable= for
|
||
listings that do not fit on a page. The filter =org-latex-engraved-source-block-filter= in listing
|
||
[[lst:org-latex-engraved-source-block-filter]] and the =org-latex-engraved-preamble= customization in listing
|
||
[[lst:smart-latex-engrave-org-source-blocks]] allow to engrave =org-mode= source
|
||
blocks to "floating unbreakable with caption" or "non-floating breakable
|
||
without caption" LaTeX environments. This is a partial work-around, but part
|
||
of my workflow.
|
||
2. Listing [[lst:ox-engraved-emacs-lisp-setup]] shows how to use this configuration.

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)]],

|
||
Listing [[lst:org-babel-latex-header-blocks]] implements this way by means of two
|

new [[info:org#Editing Source Code][<LANGUAGE>-modes]]: =latex-header= and =latex-extra-header=.

this broken function (broken, since it relies on support only in org-mode before

=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.

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

[[https://github.com/joaotavora/eglot#readme][Emacs polyGLOT (Eglot)]] is an Emacs language-server-protocol client that stays

listings contribute to a programming language mode independent [[https://github.com/joaotavora/eglot][Eglot]]

configuration:

1. Listing [[lst:minimal-eglot-setup][minimal Eglot setup]] ensures installation of [[https://github.com/joaotavora/eglot][Eglot]], shows how to get

debug information from the [[https://github.com/python-lsp/python-lsp-server][Python LSP server]], and adds key bindings to =eglot-mode-keymap=.
|

2. Listing [[lst:help-setup-org-src-mode-for-eglot]] and

[[lst:setup-python-org-src-mode-for-eglot]] try to prepare any =org-src-mode=

3. Listing [[lst:narrow-format-all-python]] defines a function to format only the

in listing [[lst:setup-python-org-src-mode-for-eglot]]. *Do not use* =format-all-buffer= *on such buffers*, since =format-all-buffer= does not

Listing [[lst:configure-sly]] configures the [[info:sly#Top][Sly (info)]] Common Lisp IDE for Emacs
|
||
for use with [[http://www.sbcl.org/][Steel Bank Common Lisp (sbcl)]]:
|
||
1. It configures =sly-default-lisp= and =sly-lisp-implementations= as in the ~sly~ documentation string instead of in the [[info:sly#Multiple Lisps][multiple lisps (info)]] manual.
|
||
2. It does not ensure the [[info:sly#Auto-SLY][automatic connection to the lisp server (info)]] when
|
||
opening a Common Lisp file because it does not play well with =ob-lisp=.
|
||
3. It configures searching documentation in the [[http://www.lispworks.com/documentation/HyperSpec/Front/][Common Lisp HyperSpec]] according
|
||
to the [[info:sly#Basic customization][basic customization (info)]] manual.
|
||
Listing [[lst:slink-sel]] allows to set or get the Sly string elision length.
|
||
Finally, listing [[lst:configure-sly]] uses a technique to [[info:sly#Loading Slynk faster][load Slynk faster (info)]]
|
||
by means of a custom core file in src_emacs-lisp{no-littering-var-directory}.
|
||
Listing [[lst:sbcl-core-for-sly]] tangles to a script to dump such a [[http://www.sbcl.org/][SBCL]] core.

The [[https://www.emacswiki.org/emacs/PythonProgrammingInEmacs][Python Programming in Emacs]] wiki page lists options to enhance Emacs's
|
||
built-in ~python-mode~. Here, the focus is on two Emacs packages and four Python
|
||
packages:
|
||
1. [[#sec:eglot][Eglot - Emacs polyGLOT: a builtin LSP client since Emacs-29.0.91]]. 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 on [[https://github.com/joaotavora/eglot/issues/523][org-mode source code blocks]]
|
||
shows.
|
||
2. [[https://jedi.readthedocs.io/en/latest/][Jedi]] is a static analysis tool for Python that is typically used in plugins
|
||
for editors or integrated development environments. Jedi has a focus on
|
||
autocompletion and object definition lookup functionality.
|
||
3. [[https://github.com/charliermarsh/ruff#readme][Ruff]] is an extremely fast Python linter and a replacement for [[https://flake8.pycqa.org/en/latest/][Flake8]] with a
|
||
variety of its plugins. [[https://notes.crmarsh.com/][Charlie Marsh]] explains why he started [[https://pypi.org/project/ruff/][Ruff]] in the
|
||
post [[https://notes.crmarsh.com/python-tooling-could-be-much-much-faster][Python tooling could be much faster]].
|
||
4. [[https://github.com/python-lsp/python-lsp-server#readme][Python LSP Server]] is in my opinion the most complete [[https://en.wikipedia.org/wiki/Language_Server_Protocol][Language Server Protocol]]
|
||
implementation for Python and it handles [[https://github.com/charliermarsh/ruff#readme][Ruff]] thanks to the [[https://github.com/python-lsp/python-lsp-ruff][python-lsp-ruff]]
|
||
plugin.
|
||
5. [[https://github.com/astoff/code-cells.el#readme][Code-cells]] allows to edit [[https://ipython.org/notebook.html][IPython or Jupyter notebooks]] in Emacs with help
|
||
from either [[https://github.com/mwouts/jupytext][Jupytext]] or [[https://pandoc.org/][Pandoc]].

Listing [[lst:setup-python-mode][setup Python mode]] and [[lst:choose-common-python-interpreter][choose common Python interpreter]] select a common
|
||
Python interpreter in a virtual environment for use in =python-mode= and
|
||
=ob-python= by means of src_emacs-lisp{(choose-common-python-interpreter)}. The
|
||
[[https://github.com/pythonic-emacs/pythonic#readme][pythonic]], [[https://github.com/jorgenschaefer/pyvenv#readme][pyvenv]], and [[https://github.com/jorgenschaefer/pyvenv#readme][pyvenv]] packages allow 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]]) or tweak the environment variables and restart the relevant Python
|
||
child processes (in case of [[https://github.com/jorgenschaefer/pyvenv#readme][pyvenv]]). Therefore, I replace those packages with
|
||
listing [[lst:access-pyenv][access pyenv]] and [[lst:select-python-virtual-environment][select a Python interpreter in a virtual environment]] to
|
||
set =python-shell-virtualenv-root= from within Emacs.
|
||
|
||
Listing [[lst:setup-python-mode][setup Python mode]] and [[lst:choose-common-python-linter][choose common Python linter]] select a common Python
|
||
linter for the =python-check-command= and the =python-flymake-command= by means
|
||
of src_emacs-lisp{(choose-common-python-linter)} from:
|
||
1. [[https://github.com/PyCQA/pyflakes][Pyflakes - simple tool which checks Python source files for errors]].
|

2. [[https://flake8.pycqa.org/en/latest/][Flake8 - your tool for style guide enforcement]].

Listing [[lst:pyproject-toml-kickoff][kickoff pyproject.toml proposal]] facilitates dropping a [[https://pip.pypa.io/en/stable/reference/build-system/pyproject-toml][pyproject.toml]]
|
||
file into Python projects which anyhow should switch to using a [[https://pip.pypa.io/en/stable/reference/build-system/pyproject-toml][pyproject.toml]]
|
||
file as explained in the post [[https://bbc.github.io/cloudfit-public-docs/packaging/this_way_up.html][This Way Up: A Bottom-Up Look At Python Packaging]].
|
||
The [[https://packaging.python.org/en/latest/tutorials/packaging-projects/][packaging Python projects tutorial]] and the [[https://github.com/pypa/sampleproject][Python sample project]] walk you
|
||
through the process of writing a [[https://pip.pypa.io/en/stable/reference/build-system/pyproject-toml][pyproject.toml]] file. [[https://github.com/charliermarsh/ruff#does-ruff-support-numpy--or-google-style-docstrings][Ruff docstring setup]]
|
||
explains how to setup documentation string checking in the [[https://pip.pypa.io/en/stable/reference/build-system/pyproject-toml][pyproject.toml]] file.
|
||
|
||
Listing [[lst:setup-cfg-kickoff][kickoff setup.cfg proposal]] implements the [[https://black.readthedocs.io/en/stable/guides/using_black_with_other_tools.html][using black with other tools]]

rules which make [[https://flake8.pycqa.org/en/latest/][flake8]] or [[https://pycodestyle.pycqa.org/en/latest/][pycodestyle]] agree with [[https://black.readthedocs.io/en/stable/index.html][black's uncompromising style]].
|

Finally, listing [[lst:flake8-nocolor][flake8-nocolor]] and [[lst:ruff-nocolor][ruff-nocolor]] pipe the =stdout= output of the

[[https://pypi.org/project/flake8/][flake8]] and [[https://pypi.org/project/ruff/][ruff]] executables through =cat= to remove escape sequences.

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
|
||
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]].

Listing [[lst:ensure-hyperbole-installation][ensure Hyperbole installation]] works around two [[https://www.gnu.org/software/hyperbole/][GNU Hyperbole]] quirks:
|
||
1. The [[https://elpa.gnu.org/elpa/hyperbole.html][GNU ELPA Hyperbole]] and [[https://elpa.gnu.org/devel/hyperbole.html][GNU ELPA Hyperbole developer]] packages ship their
|
||
own =hyperbole-autoloads= and =kotl-autoloads= files which are incompatible
|
||
with Emacs Lisp packages from "package archives". Consequently, Emacs can
|
||
neither autoload nor load the =hyperbole-autoloads= and =kotl-autoloads=
|
||
files. Therefore, the predicate loading the =kotl-autoloads= file in the
|
||
first =unless= form of listing [[lst:ensure-hyperbole-installation][ensure Hyperbole installation]] will fail and
|
||
the body of this form will overwrite the =hyperbole-autoloads= file to fix =load-path= *and* load the =hyperbole-autoloads= and =kotl-autoloads= files.
|
||
A next time, Emacs will be able to autoload the new =hyperbole-autoloads=
|
||
file but not the =kotl-autoloads= file. However, Emacs will now be able to
|
||
load the =kotl-autoloads= file which the predicate in the first =unless= form
|
||
of listing [[lst:ensure-hyperbole-installation][ensure Hyperbole installation]] does.
|
||
2. [[https://www.gnu.org/software/hyperbole/][GNU Hyperbole]] and [[info:vertico#Top][Vertico (info)]] do not play well together, since the =vertico-mode= preselection of the first candidate out of the full candidate
|
||
completion list interferes with =hyperbole-mode= expectations where it must
|
||
handle a full candidate list. Therefore, the function call
|
||
src_emacs-lisp{(either-hyperbole-or-vertico-mode)} handles this conflict by
|
||
toggling between =hyperbole-mode= and =vertico-mode=.
