The idea of generating an emacs config file using org-mode is taken from
Harry Schwartz’s talk about org-mode. When Emacs starts, all the elisp code
blocks from this file are parsed and used to generate the config. This is done
through org-babel. Babel is Org-mode’s ability to execute source code within
org-mode documents.
To use this config file, you need to evaluate this file on startup. This can be
done writing this line (org-babel-load-file "~/.my-emacs/README.org") into
your init.el.
NOTE: This file assumes that your org-mode config file is located into
~/.my-emacs/README.org.

library in order to write my Python wrappers around C/C++ code. Cython
provides a variant of Python syntax such as optional static type declarations
(this is not the same as mypy) that provides speed improvements when the code
is compiled. Therefore, all the Cython code you write is compiled to .c
files and then a C compiler compiles it to a shared library .so which can
be imported directly into the normal CPython interpreter.
In order to be able to compile Cython code you will need to write a
distutils/setuptools setup.py file. You can read about how to do it here.

so lets define one along with a keybinging to call it.

little tool and is especially nice for allowing you to quickly check for any
new email without leaving the terminal. However, you need to have an offline
copy of the messages where mu can search. This is done through
offlineimap. You can find how is configured in my dotfiles repository.
mu4e is the Emacs email client included with mu. It provides functionality
to search over the offline copy of my emails, move them around, and send/reply
to different mail servers.
For sending mail using SMTP, mu4e uses smtpmail in order to establish the
connection to the SMTP server. The authentication is done using auth-source
library.
As Gregory J Stein points, offlineimap won’t sync the messages sended to the
trash marked with the T label, which happens whenever you delete a message
with d. The workaround is the last function defined in the below snippet.
Activating org-mu4e you will be able to capture links or queries to your emails
and then use it as links into your org-mode files. Very handy if you want to
store emails into the agenda file.

(gitlab-ci-mode-flycheck-enable))I was using helm with org-ref in order to manage my bibliography. But this
package allow you to search and manage your BibTeX bibliography using the
minimalism of ivy.
In order to store the pdfs BibTeX assumes that the name of a pdf consist of
the reference key plus suffix .pdf.
(use-package ivy-bibtex
:ensure t
:config
;; ivy-bibtex requires ivy's `ivy--regex-ignore-order` regex builder, which
;; ignores the order of regexp tokens when searching for matching candidates.
(add-to-list 'ivy-re-builders-alist '(ivy-bibtex . ivy--regex-ignore-order))
(setq ivy-bibtex-default-action 'ivy-bibtex-insert-citation)
;; Library configuration
(setq bibtex-completion-library-path '("~/Drive/org/bibliography/pdfs/"))
(setq bibtex-completion-bibliography '("~/Drive/org/bibliography/main.bib"))
(setq bibtex-completion-notes-path "~/Drive/org/bibliography/notes/")
(global-set-key (kbd "C-c b") 'ivy-bibtex))By default emacs is used to open the pdf files using DocView or PDF
Tools. With the next snippet you will be able to open the documents as default
with p and with an external tool bounded to P.

(let ((bibtex-completion-pdf-open-function

in emacs. It divides the file on several batches and takes care of all the
operations for you allowing to edite smoothly the contents of the file.
(use-package vlf
:ensure t)This package is a template system for Emacs. It allows to type and abbreviation
and automatically expand it into function templates using TAB. All the
snippets I use are located into the /snippets folder of this repository.
(use-package yasnippet
:ensure t
:config
(add-to-list 'yas-snippet-dirs (concat conf-dir "snippets"))
(yas-global-mode 1)
(advice-add 'yas--auto-fill-wrapper :override #'ignore))This package turns parenthesis into color pairs, which enhances your visual parenthesis matching skills.
(use-package rainbow-delimiters
:ensure t
:hook (prog-mode . rainbow-delimiters-mode))I tried different packages in order to use a virtual terminal inside emacs, but
none of them convinced me so that’s why once again I’m trying a new
one. emacs-libvterm provides a bridge to libvterm to display a terminal
inside an emacs buffer.
I’m very used to vim keybindings but I never got used to have it on the
terminal. Deactivate it with the next command.
(use-package vterm
:ensure t
:bind (("C-c v" . vterm)
("C-c 4 v" . vterm-other-window))

(evil-set-initial-state 'vterm-mode 'emacs))Emacs come with a built-in sql-mode that interacts with different
databases. Configuration is pretty straightforward. This link describes how to
configure it.
(setq sql-postgres-login-params
'((user :default "postgres")
(database :default "postgres")
(server :default "localhost")
(port :default 5432)))
(add-hook 'sql-interactive-mode-hook
(lambda ()
(toggle-truncate-lines t)))
(evil-set-initial-state 'sql-interactive-mode 'emacs)Display inline calc results as overlays in markup modes as org-mode. It is
possible to activate a minor mode literate-calc-minor-mode and use the
overlays.
(use-package literate-calc-mode
:hook (org-mode . literate-calc-minor-mode)
:ensure t)- Thanks to Diego Vicente. He discovered me Emacs and
org-mode. Also, many aspects of my Emacs file are inspired by his config file.
