Lex

Libraries Extensions - little hacks for vanilla Emacs.

Introduction

An simple library that extends other libraries (mainly builtin ones) - a place to put new functions to be evaluated - little hacks to improve Emacs (our lisp machine) overall usability keeping everything more organized, providing a safe place to add new code/hacks.

The Lex is a abbreviation for Libraries Extensions.

Overview

On Emacs every user also is a developer, we twist and extend your programmable platform (LISP MACHINE) to meet our needs, to automatize boring tasks, to become more productive - using smart data transformations to quickly create new features, analyse data and processes of interest, and more, much more!

This is probably a continuum for the Emacs user life spam, forever an user developer, taking more and more control, engaging our manipulative capabilities all day long.

So, that’s why Lex was created to pull all this new functions in a common place, outside of the init.el configuration file, making easy to extend/reuse/modify the code that was already written.

By definition the new procedures should be little hacks, i.e, naturally small.

Install

Manually

Clone Lex repository to a arbitrary location:

$ git clone https://github.com/lambdart/lex ~/.emacs.d/site-elisp/lex

Compile and generate the lex-autoloads.el file.

[at-lex-root-directory]$ make all

Add Lex directory to load-path in your Emacs initialization file (init.el) and load it.

;; add to load-path
(add-to-list 'load-path "/replace/me/to/lex/full/path")

;; load lex basic features
(require 'lex-autoloads nil t)

• Note: For a more dynamic approach, load one by one, for example:
  • M-x load-library RET lex-uu RET
  • M-x load-library RET lex-load-path RET
  • …

Customize

• Note: To see all the options from Emacs directly, and to customize it, just type: M-x customize-group RET lex-uu RET.
