Introduction

The goal of this template is to provide a way to write very condensed indexes typically for courses with multiple books. It leverages LaTeX indexing by using a .idx file for organizing the index entries. The way this template can be used is by directly editing the .idx file.

See folder examples for some real-life indexes which have already desmontrated their effectiveness.

Here is an example preview:

Structure

The template is structured in the following way:

  • main.tex: This is the main TeX file to be compiled. No need to edit this file unless you require to adapt the layout of the course index.
  • main.idx: This holds the index entries of the books of the course to be indexed.
  • data.tex: This defines a few course-related variables (title, code, date and version) to be used in main.tex.
  • lib: This folder contains the images called in main.tex and for use in main.idx (useful e.g. for mentioning that a tool is only for linux ; then use the \linux command in the \indexentry).

Compilation

The compilation can easilly be configured in Texmaker by defining a Quick Build Command:

  1. Go to the menu Options
  2. Select Configure Texmaker
  3. Go to tab Quick Build
  4. In the field User : (…), replace the command with:

    makeindex %.idx -s lib/std.ist|pdflatex -synctex=1 -interaction=nonstopmode %.tex|evince %.pdf|cp %.idx %.idx.bak|rm %.ilg %.ind %.aux %.synctex.gz
    
  5. Then click OK

When editing the index with Texmaker:

  1. Open main.tex
  2. Go to the menu Options
  3. Select Define Current Document as “Master Document”
  4. Open main.idx for edition
  5. Click on Quick Build to compile

This will produce main.pdf with all the index entries organized in a two-columns document.

NB: Do not forget to edit data.tex.

Important: It could happen that Texmaker is configured to remove temporary files while exiting, including main.idx. That’s why the Quick Build herebefore includes cp %.idx %.idx.bak to backup this file and not to loose hours of work adding index entries. If removal still occurred, simply restore main.idx.bak to main.idx. Note that, consequently, the backup is not made if you do not build the document. So, mind clicking regularly on the Quick Build button !

Making your index

The only files to be edited when making a new index are:

  1. data.tex: Define the course attributes there (title, code, date, version).
  2. main.idx: Define the index entries there.

idx File Structure

main.idx file comes organized with a few example sections. Basically, one section represents a symbol, a digit or a letter for sorting the references. In this template:

  • Symbols are reserved for the Topics section (e.g. for providing the course structure)
  • Digits are reserved for the Categories section (e.g. for sorting interesting resources such as tools, commands, standards, …)
  • Letters are used normally

The Topics and Categories titles are defined in lib/std.ist.

LaTeX Indexing Basics

The raw material of an idx file is the indexentry. The signature of this command is the following:

\indexentry{some_text}{page_number_or_range}

Example of valid index entry: \indexentry{\textbf{Course Philosophy}}{1-10}

It is possible to provide a reference and to alias it with a desired text thanks to the “@” symbol:

\indexentry{reference@some_text}{page_number_or_range}

Important note: The format of reference affects the index reference location. That is, an alias consisting of:

  • 1+ digits and 1+ letters: will be sorted as a symbol, thus in the Topics section.
  • only digits: will be sorted as a number, thus in the Categories section.
  • 1+ letters then anything else: will be sorted as text, thus in the letter sections.

It is also possible to indent a reference under another one thanks to the “!” symbol:

\indexentry{some_text!some_indented_text}{page_number_or_range}

Example of valid index entry: \indexentry{\textbf{Course Philosophy}!Principle 1}{10}

One can format the page number by using the “|” symbol:

\indexentry{some_text!some_indented_text|command}{page_number_or_range}

Example of valid index entry: \indexentry{\textbf{Course Philosophy}|textbf}{10}

Commands Available in the Template

main.tex defines a few useful commands that can be mixed with indexentry in main.idx. Note that, in the following descriptions, ... must each time be set so that the entry is sorted at the right location in the document.

  • Adding a blank line: \blankline

    \indexentry{...@\blankline|comment}{0}
    

    Example: \indexentry{1b@\blankline|comment}{0}

  • Insert a page break: \newpage (standard in LaTeX)

    \indexentry{...@\blankline|newpage \comment}{0}
    

    Example: \indexentry{999@\blankline|newpage \comment}{0}

  • Fill in the page number with the book code: \book{x}

    \indexentry{...|book{x}}{...}
    

    Example: \indexentry{A reference in the third book|book{3}}{123}

  • Insert a rating with stars: \rate{x}

    \indexentry{... \rate{x}|...}{...}
    

    Example: \indexentry{A very useful reference \rate{5}|book{1}}{45}

  • Insert graphics: \linux, \mac, \win, \all, …

    \indexentry{... \[graphic]|...}{...}
    

    Example: \indexentry{A Windows-related reference \win|book{2}}{67}

Predefined Icons

For convenience, multiple shorcuts are predefined in main.tex and the lib folder for displaying icons:

  • \all: cross-platform ; Linux, Windows and Mac
  • \android: Android
  • \cloud: cloud icon with a server
  • \coin: dollar (for paid asset)
  • \ios: iOS
  • \linux: Linux
  • \mac: Mac OS
  • \note: paper note with a pen
  • \portable: USB key
  • \python: Python script
  • \script: general-purpose script
  • \question: red question mark (e.g. for pointing an entry related to an exam question)
  • \solaris: Soralis
  • \web: Web-related asset
  • \win: Windows
