# Latex-Makefile

Ultimate Latex Makefile with Example: https://github.com/janzhou/latex-makefile

# Windows Subsystem for Linux (Bash on Windows)

To use under bash on windows, convert the bash scripts to unix format:

dos2unix share/bin/*

# Usage

## Suggested Tools

For Debian/Ubuntu based systems, install:

sudo apt install make texlive-full inotify-tools biber bibtool poppler-utils python-pygments

## Init your project:

Clone the makefile:

git clone https://github.com/janzhou/latex-makefile

Do not touch the existing files unless you want to develop the makefile. All your latex files should be placed in standalone directories.

## Put your latex files in sub folder:

Create a new sub folder to start editing. e.g. If you want to generate article.pdf, create a folder named article.

cp example.tex article.tex

The compiling script will start from article.tex/index.tex or article.tex/article.tex.

In using index.tex it is easier for you to rename the sub folder.

In using article.tex like file, you can more easily compile the .tex files to article.pdf in standalone compilers. e.g. You may compile it using MiKTeX GUI program.

## Compile

The compiler will automatically find all the sub folders, and solve the dependencies. Each sub folder will compiled to a pdf file. Just use GNU Make:

make

You can also compile specific pdf file by use the filename as the parameter. e.g.

make article.pdf

If you are using multicore CPUs, and you want to compile multiple pdfs concurrently. The Makefile can find the number of CPU Cores, and do multi threaded compiling:

make multicore

## Watch Changes

The Makefile can watch the changes in the directories and compile the pdfs automatically when files modified. There are two scripts included. One is using a loop to compile the pdfs:

make watch

The other one is using inotify to watch the file changes in the directories (require inotify-tools in debian based system):

make watch-inotify

Use the one that works for you. Because in each make, the Makefile will search the dependencies, this will result in warnnings like this:

.makefile/example.makefile:9: warning: overriding recipe for target 'example.pdf'
;�-:9: warning: ignoring old recipe for target 'example.pdf'

Alternatively you can use shell scripts located in share/bin/watch and share/bin/watch-inotify to avoid the warning.

# Advanced Usage

## Upgrade the Makefile

To upgrade the Makefile, simply use command:

make pull

In order to not break the upgrade, please do not touch any existing files and directories such as:

• example
• share
• Makefile

## Override Makefile

If you need to customize the Makefile, place your stuff in .configure.

## Config the compiler

The Makefile will use xelatex by default, if you want to override this, create a file article/config and write:

latex=lualatex

The supported compilers are pdflatex, lualatex.

You can also override bib compiler:

bib=biber

## Latexmk support

Makefile alone can not get the correct dependency setting to make the compiler run latex and bibtex properly. That is why the most safer action is chose. In the default pdf generating process, we run latex, bibtex, latexandlatexin a row. If we modify any contents, we rerun the above commands to grantee we get the correctpdf. This is unnecessary and only latexneeded to be rerun once if we make minor changes in.tex files, which is very common.

Latexmk au­to­mates the pro­cess of gen­er­at­ing a LaTeX doc­u­ment. It runs latex and bibtex based on the changes you made. It can also use biber automatically if you use it.

Latexmk is disabled in the Makefile by default. To enable it, add the following code in config:

latexmk=1

## TEXMF Search Path

Suppose you are compiling article.pdf. These paths will be searched in order: article, ., article.tex/texmf and share/texmf.

If you have customized .sty, .bst, .cls files, you can place them in article. Or you can place them in article.tex/texmf to keep your top level directory clean.

Because . is included in the search path, you can include files from other sub folders by using \input{other-articles/example.tex} (replace other-articles with real path).

The use of share/texmf should be avoided, as it is supposed to put some shared files.

## Dependency between pdfs

If you need to include files from other latex sources, it would be wise to explicitly add dependencies in the make file. So that the changes in the source pdf would cause rebuild in the destiny pdf. This is done by add depend configuration in config file:

depend="source1 source2"

## Default Variables you can use in .tex files

You can use some default variables in your .tex files:

• \id: The current folder/pdf name. e.g. In .tex files in folder article, the \id should be equal to article.
• \version: This is the git version you can use in your .tex files. You can also use \include{version} to stay safer (\version will be undefined if you use it in standalone compiler. share/texmf/version.tex will check if \version is defined for you.).
• \wordcount: The words in text. It use texcount to counts words in index.tex and all the \input files. But because of the limitation of texcount, \id in file path is not supported (see #6 for details).

# Tip: Collaborate using Dropbox

This Makefile works better while collaborating with Dropbox.

One of the headache of collaborate on a latex project is every collaborator need to setup the same compiling tools. It is often not that easy. And you can not simply pick up a computer and start to work before install the correct tools on that computer.

ShareLaTeX is a good collaborating tool. But it is either a little bit expensive or hard to setup your own server.

Dropbox is a grate sync & collaborate tool. It is the only cloud storage that has official Linux support. But no support for latex.

We can setup a Dropbox shared folder to collaborate on the latex projects. We then can sync the files to a Linux machine to compile them in a background terminal like GNU Screen. The machine can be any Linux desktop or server with latex tools installed and an access to Internet, and need not to be public accessible. It is cheep.

Each latex project can be place in an independent folder and be compiled automatically by the Makefile. The compiler generated files is located in out directory under each project folder. We can find the pdf file in out directory and see the .log file to debug the compiling error.

Known bugs:

• To watch the latex changes, the watch script use a loop method, but it may flush the .log file too quickly if there are errors. As a result, you may not have time to see the error information.
• The watch-inotify use inotify to trigger make command while file changes detected. But, it may failed to detect some of the file changes because of the file sync problem. So, you have to pretend to change the files to trigger the compiling occasionally.
