Introduction

Emacs customisation generates init.el and other emacs elisp utility files using org-babel-tangle.

scratch

(let ((foo "foo")
      (bar "bar"))
  (concat bar foo))

Own libraries

These libraries are seperate stand alone github libraries.

el-docstring-sap

Provides docstring help for symbol at point.

lazy-lang-learn

A small "game" like utility that displays snippets to glance at. You can then invoke google translate on them. Stores history.

Security

Raw: rgr/security

(require 'rgr/security "rgr-security" 'NOERROR)

library

Auth-Sources, get-auth-info

Let emacs take care of security things automagically. example:

(setq passw (get-auth-info "licenses" "my-auth-token"))

(require 'auth-source)
(defun get-auth-info (host user &optional port)
  "Interface to `auth-source-search' to fetch a secret for the HOST and USER."
  (let* ((info (nth 0 (auth-source-search
                       :host host
                       :user user
                       :port port
                       :require '(:user :secret)
                       :create nil)))
         (secret (plist-get info :secret)))
    (if (functionp secret)
        (funcall secret)
      secret)))

Pass

Uses the unix command line pass utility. Can be used via process-lines e.g
```
(car (process-lines "pass" "Chat/slack-api-token"))

(use-package pass)
```
provide
```
(provide 'rgr/security)

Setting up emacs as a default editor using a dot desktop file and associated protocol handler

php.ini changes e.g /etc/php/7.3/php.ini

xdebug.file_link_format is used by compliant apps to format a protocol uri. This is handled on my Linux system as a result of emacsclient.desktop documented below.

xdebug.file_link_format = "emacsclient://%f@%l"

xdebug.remote_enable = 1
xdebug.remote_host = localhost
xdebug.remote_port = 9000

xdebug.file_link_format = "emacsclient://%f@%l"

xdebug.remote_enable = 1
xdebug.remote_host = localhost
xdebug.remote_port = 9000

emacsclient-linenumber script to correctly parse the protocol in order to start emacs frame at correct line

#!/usr/bin/bash
# Maintained in emacs-config.org
export GDK_NATIVE_WINDOWS=1
file=`echo "$@" | sed 's/.*://;s/@.*$//'`
line=`echo "$@" | sed 's/.*@//'`
echo $file
echo $line

re='^[0-9]+$'
if ! [[ $line =~ $re ]] ; then
    exec emacsclient -c -a ""  $file
else
    exec emacsclient -c -a "" +$line  $file
fi

Gnome protocol handler desktop file

Copy emacsclient.desktop to ~/.local/share/applications (Debian & Gnome - your mileage may vary…)

[Desktop Entry]
Name=Emacs (Client)
GenericName=Text Editor
Comment=Edit text
MimeType=text/english;text/plain;text/x-makefile;text/x-c++hdr;text/x-c++src;text/x-chdr;text/x-csrc;text/x-java;text/x-moc;text/x-pascal;text/x-tcl;text/x-tex;application/x-shellscript;text/x-c;text/x-c++;
Exec=emacsclient -c -a "" %F
Icon=emacs
Type=Application
Terminal=false
Categories=Development;TextEditor;Utility;
StartupWMClass=Emacs

Update the desktop database:

update-desktop-database ~/.local/share/applications

now allows emacsclient to be called.

note: symlink the deprecated ~/.local/share/applications/mimeapps.lst to the one in ~/.config

ln -sf  ~/config/mimeapps.lst ~/.local/share/applications/

Always using emacsclient

Set up a zshrc alias so that "emacs" actually invokes emacs client. In my .zshrc:

alias emacs='emacsclient --create-frame --alternate-editor=""'

bin/emacs-same-frame open emacs in the same frame

#!/bin/bash
if ! pidof "emacs"; then
    emacsclient -n -c -a "" "$@"
else
    emacsclient -e "(if (> (length (frame-list)) 1) 't)" | grep -q t
    if [ "$?" = 1 ]; then
        emacsclient -n -c -a "" "$@"
    else
        emacsclient -n -a "" "$@"
        pop-window "Emacs"
    fi
fi
