I hate LaTeX. Problem is, the forest package is still the only way to make presentable syntax trees. So here’s a way to convert LaTeX trees into individual .svg files that can be inserted into your documents without getting all pixelated.
Prerequisites: I have TeXLive installed on Windows, which comes with the dvisvgm command-line utility. The latex command generates .dvi files that dvisvgm converts to svg. If you can open up a fresh terminal and run dvisvgm, you’re probably good.
Usage: python tree-generator.py FILENAME.tex. The script will hunt for anything between \begin{forest} and \end{forest} and turn it into its own individual .svg file. These .svg files can be inserted into Microsoft Word and LibreOffice Writer but not Google Docs (grrr).
Script:
import sys
import re
import subprocess
import os
with open(sys.argv[1], 'r') as file:
content = file.read()
content = content.replace('\t', '').replace('\n', '')
trees = re.findall(r'\\begin{forest}.*?\\end{forest}', content)
for index, tree in enumerate(trees):
latex = "\\documentclass[12pt]{standalone}\\usepackage{forest}\\usepackage{times}\\begin{document}" + tree + "\\end{document}"
with open("temp-latex.tex", "w", encoding='utf-8') as f:
f.write(latex)
print('converting tree ' + str(index) + ' into dvi...')
subprocess.run(['latex', 'temp-latex.tex'])
print('converting tree ' + str(index) + ' into svg...')
subprocess.run(['dvisvgm', '-n', 'temp-latex.dvi'])
print('cleaning up...')
os.rename('temp-latex.svg', 'tree-' + str(index) + '.svg')
os.remove('temp-latex.tex')
os.remove('temp-latex.aux')
os.remove('temp-latex.dvi')
os.remove('temp-latex.log')
