#+TITLE: How to Migrate LaTeX Template into org-mode


* Summary                                                          

This =How-To= tutorial provides a step by step guide on how to migrate[fn:1] the LaTeX template provided by an academic journal into =org-mode= syntax. 

** Instructions

To complete this tutorial successfully, please follow all steps in the order presented of each section listed below:
- Requirements
- Create New =org-mode= File
- Download LaTeX Template
- Migrate LaTeX Template Code into =file variables=
- Migrate LaTeX Template Code into =SRC= blocks
- Customize a =SRC= block using Literate Programming
- Add Content to =org-mode= File
- Export completed =org-mode= file as =PDF=

* Requirements

#+BEGIN_QUOTE
  *Note:* All the requirements /must/ be completed successfully before continuing with the steps in this =How-To= tutorial.
#+END_QUOTE

** Instructions

1. Download, Install, and Configure LaTeX Software

   Unfortunately, this requirement is beyond the scope of this =How-To= tutorial.

2. Download, Install, and Configure =Emacs= Software

   Unfortunately, this requirement is beyond the scope of this =How-To= tutorial.

3. Download, Install, and Configure =org-mode= Software

   #+BEGIN_QUOTE
     *Note:* The =org-mode= application is already installed if you are using a recent version of =Emacs=, i.e. versions 25 or greater.
   #+END_QUOTE

   Unfortunately, this requirement is beyond the scope of this =How-To= tutorial.

4. Export an =org-mode= file as =PDF= via built-in LaTeX exporter.
   
   #+BEGIN_QUOTE
   *TIP:* To export an =org-mode= document to =PDF=:  
      1. Open the =org-mode= file in =Emacs=.  
      2. Position the cursor in the buffer of the =org-mode= document in =Emacs=.  
      3. Press the following key chords and keys, ~C-c~ ~C-e~ ~l~ ~p~ to initiate the export process.
      4. Open the exported =PDF= file to validate the export process succeeded.
   #+END_QUOTE

   If exporting an =org-mode= file to =PDF= succeeded then continue following the steps in this =How-To= tutorial. Otherwise troubleshoot each step in the requirements section and repeat until exporting an =org-mode= document to =PDF= is successful.

* Create New org-mode File

** Instructions

1. Create a new =org-mode= file using =Emacs=.

   For this tutorial, the filename will be =journal-template.org=

   - To create the file in Emacs do the following: 
     1. Press the key chords ~C-x~ ~C-f~
     2. Type =journal-template.org=
     3. Press ~Return~ or ~Enter~ key

2. Add ~mode~ line to top of the file.
   
   #+NAME: mode-line
   #+BEGIN_SRC org
     # -*- mode: org; org-confirm-babel-evaluate: nil; org-babel-noweb-wrap-start: "«"; org-babel-noweb-wrap-end: "»"; -*-
   #+END_SRC

   #+BEGIN_QUOTE 
     *TIP:* To insert =«= press key chord ~C-x~ ~8~ ~<~ and to insert =»= press key chord ~C-x~ ~8~ ~>~ 
   #+END_QUOTE

3. Add /Template Utility Code/ Section to end of file.
   
   #+NAME: template-utility-code
   #+BEGIN_SRC org
     ,* Template Utility Code                                            :noexport:

   #+END_SRC

4. Add /Common Export Settings/ Section to end of the file.

   #+NAME: common-export-settings
   #+BEGIN_SRC org
     ,* Common Export Settings                                           :noexport:

     ,#+OPTIONS: ':nil *:t -:t ::t <:nil H:4 \n:nil ^:{} arch:headline
     ,#+OPTIONS: author:nil broken-links:nil c:nil creator:nil
     ,#+OPTIONS: d:(not "LOGBOOK") date:nil e:t email:nil f:t inline:t num:nil
     ,#+OPTIONS: p:nil pri:nil prop:t stat:nil tags:t tasks:nil tex:t
     ,#+OPTIONS: timestamp:nil title:nil toc:nil todo:nil |:t
     ,#+SELECT_TAGS: export
     ,#+EXCLUDE_TAGS: noexport nolatex

     # For Display when file is exported with org-ruby 

     ,#+EXPORT_SELECT_TAGS: export
     ,#+EXPORT_EXCLUDE_TAGS: noexport
   #+END_SRC

5. Save the file in =Emacs=.

   - To save the file in Emacs do the following: 
     1. Press the key chords ~C-x~ ~C-s~

** Self Check - Example 1

After completing the instructions in this section, the contents of journal-template.org should be similar to [[file:self-check-example-01.org][self-check-example-01.org]].

#+BEGIN_SRC org :tangle self-check-example-01.org :noweb yes :exports none 
  «mode-line»

  «template-utility-code»
  «common-export-settings»
#+END_SRC

* Download LaTeX Template

For this =How-To= tutorial, the LaTeX template[fn:2] provided by the European Physical Journal A (EPJ A)[fn:3] will be used.

The following 3 files provided by the EPJ A will be needed in this tutorial:

 - *template.tex*

   The =template.tex= file is provided as "[a] fill-in-form for a standard article with usage comments"[fn:4].

   The objective of this =How-To= tutorial is migrate LaTeX code from =template.tex= into the new =org-mode= file.

 - *svepj.clo*

   The =svepj.clo= is the LaTeX "[c]lass option file for The European Physical Journal"[fn:5].

 - *svjour.cls*

   The =svjour.cls= is the LaTeX "[c]ore document class file for Springer journals"[fn:6].

** Instructions

1. Download [[file:template.tex][template.tex]] file into same directory as =journal-template.org=.

* Migrate LaTeX Template Code into =file variables=

In this section, the objective is migrate[fn:7][fn:8] LaTeX code from LaTeX template into [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Specifying-File-Variables.html][file variables]] syntax at the bottom of the =org-mode= file. The file variables will be used when exporting from =org-mode= back to LaTeX.

The LaTeX code that will be migrated into file variables syntax is located near the top of [[file:template.tex][template.tex]] file:

#+BEGIN_SRC org :noweb yes :wrap "SRC latex :eval never :exports code" :exports results  :results replace 
  «ups-template-begin-latex-code»
#+END_SRC

* Migrate LaTeX Template Code into =SRC= blocks

In this section, the object is to migrate specific snippets of LaTeX code from the LaTeX template into =SRC= block syntax provided by =org-mode=. Each =SRC= block will inject customized LaTeX into the final LaTeX document created by the built-in exporter. 

These template specific =SRC= blocks will be kept under a dedicated section named =Template Utility Code= which will not be exported. 

** Instructions

1. Add the following lines *after* the =* Template Utitily Code= section in the journal-template.org document.
