#+TITLE: chaseadamsio/goorgeous
[[https://travis-ci.org/chaseadamsio/goorgeous.svg?branch=master]]
[[https://coveralls.io/repos/github/chaseadamsio/goorgeous/badge.svg?branch=master]]
/goorgeous is a Go Org to HTML Parser./
[[file:gopher_small.gif]]
*Pronounced: Go? Org? Yes!*
#+BEGIN_QUOTE
"Org mode is for keeping notes, maintaining TODO lists, planning projects, and authoring documents with a fast and effective plain-text system."
- [[orgmode.org]]
#+END_QUOTE
The purpose of this package is to come as close as possible as parsing an =*.org= document into HTML, the same way one might publish [[http://orgmode.org/worg/org-tutorials/org-publish-html-tutorial.html][with org-publish-html from Emacs]].
* Installation
#+BEGIN_SRC sh
go get -u github.com/chaseadamsio/goorgeous
#+END_SRC
* Usage
** Org Headers
To retrieve the headers from a =[]byte=, call =OrgHeaders= and it will return a =map[string]interface{}=:
#+BEGIN_SRC go
input := "#+title: goorgeous\n* Some Headline\n"
out := goorgeous.OrgHeaders(input)
#+END_SRC
#+BEGIN_SRC go
map[string]interface{}{
"title": "goorgeous"
}
#+END_SRC
** Org Content
After importing =github.com/chaseadamsio/goorgeous=, you can call =Org= with a =[]byte= and it will return an =html= version of the content as a =[]byte=
#+BEGIN_SRC go
input := "#+TITLE: goorgeous\n* Some Headline\n"
out := goorgeous.Org(input)
#+END_SRC
=out= will be:
#+BEGIN_SRC html
<h1>Some Headline</h1>/n
#+END_SRC
* Why?
First off, I've become an unapologetic user of Emacs & ever since finding =org-mode= I use it for anything having to do with writing content, organizing my life and keeping documentation of my days/weeks/months.
Although I like Emacs & =emacs-lisp=, I publish all of my html sites with [[https://gohugo.io][Hugo Static Site Generator]] and wanted to be able to write my content in =org-mode= in Emacs rather than markdown.
Hugo's implementation of templating and speed are unmatched, so the only way I knew for sure I could continue to use Hugo and write in =org-mode= seamlessly was to write a golang parser for org content and submit a PR for Hugo to use it.
* Acknowledgements
I leaned heavily on russross' [[https://github.com/russross/blackfriday][blackfriday markdown renderer]] as both an example of how to write a parser (with some updates to leverage the go we know today) and reusing the blackfriday HTML Renderer so I didn't have to write my own!
