manuscript-tools 0.1.0

Validation, sanitization and metrics for Markdown manuscripts.

manuscript-tools

A Python toolkit for validating, sanitizing and measuring Markdown manuscripts. Built for authors who automate their publishing workflow.

Deutsche Version

What it does

ms-check scans your manuscript for style violations. Ships with two built-in rules (typographic dashes, invisible Unicode characters) and supports custom rules as simple Python callables.

ms-sanitize fixes encoding issues, normalizes Unicode (NFKC), strips invisible control characters, replaces problematic whitespace and ensures consistent line endings. Supports dry-run and backup modes.

ms-metrics reports word counts, line counts and character counts per file and in total. Uses regex-based word boundary matching instead of naive whitespace splitting, so Markdown syntax characters are not counted as words.

Requirements

• Python 3.11+
• Poetry

Installation

git clone <your-repo-url> manuscript-tools
cd manuscript-tools
make install

Or manually:

poetry install

Usage

All commands accept a path (file or directory, default: manuscript/), --include and --exclude glob patterns.

Style checks

make check
# or with custom path
make check MANUSCRIPT=chapters/
# or directly
poetry run ms-check manuscript/ --exclude 'drafts/*'

Output per file: rule name, violation message and line number. Exit code 1 if any violations are found.

Sanitization

# Preview changes without writing
make sanitize-dry

# Apply changes with backup
make sanitize-backup

# Apply changes in-place (no backup)
make sanitize

Text metrics

make metrics

Output:

chapter-01.md                     3,412 words   187 lines
chapter-02.md                     2,891 words   154 lines
----------------------------------------
Total                             6,303 words   341 lines    38,219 chars

Combined validation

# Runs sanitize dry-run followed by style check
make validate

Writing custom rules

A rule is any callable with the signature (text: str, path: Path) -> list[StyleViolation].

from pathlib import Path
from manuscript_tools.checker import check_file
from manuscript_tools.models import StyleViolation


def rule_no_todos(text: str, path: Path) -> list[StyleViolation]:
    return [
        StyleViolation(file=path, rule="no-todos", message="TODO found", line=i)
        for i, line in enumerate(text.splitlines(), start=1)
        if "TODO" in line
    ]


report = check_file(Path("chapter.md"), rules=[rule_no_todos])
