Problem and Solution

#	Problem	Solution
1	Hand-authored .tex from Python is brittle — escaping _ / & / % and locating the right pdflatex invocation eats hours per paper	export_tex + compile_tex — writer doc → .tex → .pdf in two calls; CompileResult exposes the pdf path + log on failure
2	Previewing a math snippet means firing up a full LaTeX project	preview(r"$\sum x_i$", "out.png") — single-call rendering via matplotlib; no system TeX install required
3	Sig-fig formatting for vectors / scalars is reinvented per script	to_vec(value, sig_figs=N) — consistent scientific notation for tables and captions

Installation

pip install scitex-tex

Quick Start

import scitex_tex as tx

# Convert a SciTeX-style writer doc → .tex
tx.export_tex(doc, "manuscript.tex")

# Compile .tex → .pdf (returns CompileResult)
result = tx.compile_tex("manuscript.tex")

# Render a snippet to a preview image
tx.preview(r"$\sum_{i=1}^N x_i$", "preview.png")

# Format a numeric value with sig-fig rules
tx.to_vec(1.234e-3, sig_figs=3)

Python API

import scitex_tex as tx

# Export — writer doc → .tex string + file
tx.export_tex(doc, "manuscript.tex")

# Compile — .tex → .pdf via pdflatex/xelatex; returns CompileResult
res = tx.compile_tex("manuscript.tex")
print(res.pdf_path, res.log)

# Preview — render a snippet to a PNG
tx.preview(r"$\frac{1}{2}\sum x_i$", "preview.png")

# Vector formatting helpers
tx.to_vec(1.234e-3, sig_figs=3)

Demo

import scitex_tex as tx

# 1) Render a math preview to PNG (no system TeX required)
tx.preview(r"$\hat{\beta} = (X^\top X)^{-1} X^\top y$", "preview.png")

# 2) Export + compile a manuscript end-to-end
tx.export_tex(doc, "manuscript.tex")
result = tx.compile_tex("manuscript.tex")
print(result.pdf_path)   # → manuscript.pdf

Status

Standalone fork of scitex.tex. Only dep is matplotlib (for preview rendering). The umbrella package's scitex.tex import path is preserved via a sys.modules-alias bridge.

Part of SciTeX

scitex-tex is part of SciTeX. Install via the umbrella with pip install scitex[tex] to use as scitex.tex (Python) or scitex tex ... (CLI).
