latex tips and tricks view markdown

Contains simple instructions for common issues with writing in latex

introduction

• really good introduction here

diffing latex projects (easy)

• from overleaf, create a latexmkrc file with this content: $pdflatex = "latexdiff main_old.tex main.tex > main-d.tex; pdflatex %O main-d"
  • Save the original version into “main_old.tex” and the current version as “main.tex”
  • This will render a marked up pdf with the differences

diffing complex latex files (hard)

Pipeline for finding the differences between 2 versions of complex latex projects.

Note: this assumes that style files for the two do not change (only changes to .tex files).

1. Download all files for the original version and the new version into folders named old and new

2. “Flatten” the tex files by replacing \input{fname.tex} with the contents of the file fname.tex
   • simple python code to do this here
   • installing (locally):

       git clone https://github.com/johnjosephhorton/flatex.git
       cd flatex
       pip install --editable . 
     

     cd old
     flatex --include_bbl _main.tex old.tex
     cd ..
     cd new
     flatex --include_bbl _main.tex new.tex
     cd ..
     

3. Copy the non-tex files (.cls, .bib, .sty, .bst, figs) you want to use to a new directory. Then From this directory download and run latexdiff on the flattened files - this should produce the desired diff!

     mkdir diff
     cp -r new/* diff/
     cp old/old.tex diff/
       
   cd diff
   latexdiff old.tex new.tex > diff.tex
   

toggling documents with a simple boolean

a simple way to use booleans in latex without needing to import any packages

defining a boolean:

\newif\ifanonymize % define a boolean named `anonymize`

\anonymizefalse % set it to false
% \anonymizetrue % set it to true

use it in an if-statement

\ifanonymize
	...
\else
	...
\fi

create a helper command named \anonfinal which takes two arguments and will print only one of them based on the boolean

\ifanonymize
  \newcommand{\anonfinal}[2]{#1}
\else
  \newcommand{\anonfinal}[2]{#2}
\fi

making figures

• figures should be saved as pdf unless they have a ton of points
