| description | Swiss army knife for Markdown — TOC generator, format conversion (MD↔HTML), broken formatting fixer, HTML stripper, file merger, YAML frontmatter validator, orphan link finder. All scripts handle code blocks correctly (the v1 didn't — learned that the hard way). Not for LaTeX, DOCX, or rich document layout. |

Markdown Toolkit
Every Markdown problem you've Googled more than twice, solved in one place.
TOC Generator (code-block-aware)
python3 << 'SCRIPT'
import re, sys
file = sys.argv[1] if len(sys.argv) > 1 else "README.md"
with open(file) as f:
lines = f.readlines()
toc, in_code = [], False
for line in lines:
if line.strip().startswith("```"):
in_code = not in_code
continue
if in_code:
continue
m = re.match(r'^(#{1,4})\s+(.+)', line)
if m:
level = len(m.group(1))
title = m.group(2).strip()
anchor = re.sub(r'[^\w\s-]', '', title.lower())
anchor = re.sub(r'\s+', '-', anchor.strip())
toc.append(f"{' ' * (level - 1)}- [{title}](#{anchor})")
print("## Table of Contents\n")
print("\n".join(toc))
SCRIPT
Important: Skips headers inside code blocks — v1 picked up # comments in bash scripts as real headers. Generates GitHub-compatible anchors.
MD → HTML
pandoc input.md -o output.html --standalone \
--css=https://cdn.simplecss.org/simple.min.css
python3 << 'SCRIPT'
import re, sys
with open(sys.argv[1]) as f:
md = f.read()
blocks = {}
c = [0]
def save(m):
k = f"__CB_{c[0]}__"; c[0] += 1
blocks[k] = f'<pre><code class="language-{m.group(1) or ""}">{m.group(2)}</code></pre>'
return k
md = re.sub(r'```(\w*)\n(.*?)```', save, md, flags=re.DOTALL)
md = re.sub(r'`(.+?)`', r'<code>\1</code>', md)
for i in range(4, 0, -1):
md = re.sub(rf'^{"#"*i}\s+(.+)$', rf'<h{i}>\1</h{i}>', md, flags=re.M)
md = re.sub(r'\*\*(.+?)\*\*', r'<strong>\1</strong>', md)
md = re.sub(r'\*(.+?)\*', r'<em>\1</em>', md)
md = re.sub(r'\[(.+?)\]\((.+?)\)', r'<a href="\2">\1</a>', md)
for k, v in blocks.items():
md = md.replace(k, v)
print(f'<!DOCTYPE html><html><head><link rel="stylesheet" href="https://cdn.simplecss.org/simple.min.css"></head><body>{md}</body></html>')

Fix Common Problems
Trailing whitespace: sed -i 's/[[:space:]]*$//' doc.md
Mixed header styles (ATX + Setext):
python3 -c "
import re, sys
with open(sys.argv[1]) as f: t = f.read()
t = re.sub(r'^(.+)\n=+\s*$', r'# \1', t, flags=re.M)
t = re.sub(r'^(.+)\n-+\s*$', r'## \1', t, flags=re.M)
print(t)" doc.md
Strip HTML from Google Docs paste:
python3 -c "
import re, sys
with open(sys.argv[1]) as f: t = f.read()
safe = 'a|img|br|hr|code|pre|em|strong|b|i'
t = re.sub(rf'<(?!/?(?:{safe})\b)[^>]+>', '', t)
t = re.sub(r' ', ' ', t)
t = re.sub(r'\n{3,}', '\n\n', t)
print(t)" doc.md
Orphan Link Finder
python3 << 'SCRIPT'
import re, sys
with open(sys.argv[1]) as f:
text = f.read()
used = set(re.findall(r'\[.+?\]\[(.+?)\]', text))
defined = set(re.findall(r'^\[(.+?)\]:', text, re.M))
orphans = used - defined
unused = defined - used
if orphans:
print(f"⚠️ {len(orphans)} orphaned: {', '.join(sorted(orphans))}")
if unused:
print(f"📎 {len(unused)} unused: {', '.join(sorted(unused))}")
if not orphans and not unused:
print("✅ All links clean")
SCRIPT
YAML Frontmatter Validator
python3 << 'SCRIPT'
import sys, yaml
with open(sys.argv[1]) as f:
content = f.read()
if not content.startswith('---'):
print("No frontmatter"); sys.exit(0)
parts = content.split('---', 2)
if len(parts) < 3:
print("❌ Missing closing ---"); sys.exit(1)
try:
meta = yaml.safe_load(parts[1])
for k, v in (meta or {}).items():
print(f" {k}: {str(v)[:80]}")
print("✅ Valid")
except yaml.YAMLError as e:
print(f"❌ {e}")
SCRIPT
File Merger
python3 << 'SCRIPT'
import os, glob, sys
d = sys.argv[1] if len(sys.argv) > 1 else "docs"
files = sorted(glob.glob(os.path.join(d, "*.md")))
for i, f in enumerate(files):
name = os.path.splitext(os.path.basename(f))[0]
if i > 0: print("\n---\n")
print(f"# {name.replace('-', ' ').title()}\n")
with open(f) as fh: print(fh.read().strip())
print(f"\n✅ Merged {len(files)} files", file=sys.stderr)

Gotchas Reference
| Gotcha | Fix |
|---|
| Trailing single space | sed -i 's/ $//' file.md |
Trailing double space (= <br>) | Keep if intentional |
| Paragraph inside ordered list restarts numbering | Indent 4 spaces |
| Bare URLs don't link | Wrap in <> |
--- at top = frontmatter, not separator | Use *** for separators |
| Images with spaces in filename | URL-encode: my%20image.png |
