latex-wc 0.2.9

Count words in LaTeX documents while ignoring commands, math, and common non-text regions.

latex-wc

A small CLI tool that counts words in LaTeX .tex files while trying to ignore LaTeX “noise”:

• Removes comments (% ...)
• Removes common math forms ($...$, $$...$$, \(...\), \[...\], and common math environments)
• Drops common non-content commands (e.g., citations/refs/urls/labels)
• Strips LaTeX command names while preserving human-visible brace text
• Tokenizes words and reports totals + top-N frequencies

Optionally writes:

• words.txt (one token per line)
• top_words.csv (ranked word frequency table)

Heuristic by design: the goal is a human-ish word count, not a TeX-perfect parse.

Install (recommended: isolated CLI via uv / pipx)

Distribution name: latex-word-count
CLI command: latex-wc
Import package: latex_wc

Option A: One-off run with uvx (no install)

uvx latex-wc ./paper.tex

If you want directory recursion:

uvx latex-wc ./tex/

Option B: Install as a persistent tool with uv

uv tool install latex-wc
latex-wc ./paper.tex

Upgrade later:

uv tool upgrade latex-wc

Option C: Install as a persistent tool with pipx

pipx install latex-wc
latex-wc ./paper.tex

Upgrade later:

pipx upgrade latex-wc

Usage

Basic

Pass either a file or a directory:

latex-wc ./paper.tex
latex-wc ./thesis/     # recursively counts all *.tex under ./thesis (one combined report)

Backwards-compatible flag

--document-path is still supported (positional PATH wins if both are provided):

latex-wc --document-path ./paper.tex
latex-wc ./paper.tex --document-path ./ignored.tex

Arguments

• PATH (positional, optional) Path to a .tex file or a directory. If omitted: uses $DOCUMENT_PATH or searches the current directory recursively.

• --top N Number of top words to display. Default: 100

• --min-len N Minimum token length to include. Default: 1

• --out-dir DIR If set, writes words.txt and top_words.csv into this directory. Default: $LOG_DIR if set; if empty, nothing is written.

• --debug Enables verbose debug logging to stderr (stdout remains the main report output).

Examples

# Count words, show top 50, ignore tokens shorter than 4 chars
latex-wc ./paper.tex --top 50 --min-len 4

# Count all .tex files under a directory (combined report)
latex-wc ./tex/ --top 25

# Write outputs to ./logs/
latex-wc ./paper.tex --out-dir ./logs

# Use env vars (no args)
DOCUMENT_PATH=./paper.tex LOG_DIR=./logs latex-wc

# Verbose debug logs
latex-wc ./paper.tex --debug

---

Output

The CLI prints:

• Document path (file mode) or directory + number of files (directory mode)
• Total words
• Unique words
• Top-N word frequency list

If --out-dir is set, two files are written:

• words.txt — one token per line
• top_words.csv — rank,word,count
