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\
")
print("\
".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

# With pandoc (handles everything)
pandoc input.md -o output.html --standalone \
  --css=https://cdn.simplecss.org/simple.min.css

# Without pandoc (pure Python, protects code blocks)
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*)\
(.*?)```', 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'^(.+)\
=+\s*$', r'# \1', t, flags=re.M)
t = re.sub(r'^(.+)\
-+\s*$', 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'&nbsp;', ' ', t)
t = re.sub(r'\
{3,}', '\
\
', 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")

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}")

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("\
---\
")
    print(f"# {name.replace('-', ' ').title()}\
")
    with open(f) as fh: print(fh.read().strip())
print(f"\
✅ Merged {len(files)} files", file=sys.stderr)
