Zig Docs

Zig Documentation Fetching

Instructions

• Use raw Codeberg sources for std lib documentation (most reliable)
• Use pandoc for language reference from ziglang.org (works for prose content)
• The std lib HTML docs at ziglang.org are JavaScript-rendered and return empty content; avoid them
• Zig source files contain doc comments (//! for module docs, /// for item docs) that serve as authoritative documentation

Quick Reference

Fetch Standard Library Source (Recommended)

Standard library modules are self-documenting. Fetch source directly:

# Module source with doc comments
curl -sL "https://codeberg.org/ziglang/zig/raw/branch/master/lib/std/<module>.zig"

# Common modules:
curl -sL "https://codeberg.org/ziglang/zig/raw/branch/master/lib/std/log.zig"
curl -sL "https://codeberg.org/ziglang/zig/raw/branch/master/lib/std/mem.zig"
curl -sL "https://codeberg.org/ziglang/zig/raw/branch/master/lib/std/fs.zig"
curl -sL "https://codeberg.org/ziglang/zig/raw/branch/master/lib/std/heap.zig"
curl -sL "https://codeberg.org/ziglang/zig/raw/branch/master/lib/std/debug.zig"
curl -sL "https://codeberg.org/ziglang/zig/raw/branch/master/lib/std/testing.zig"

Fetch Allocator Interface

curl -sL "https://codeberg.org/ziglang/zig/raw/branch/master/lib/std/mem/Allocator.zig"

Fetch Language Reference (Prose)

# Full language reference (large, ~500KB of text)
pandoc -f html -t plain "https://ziglang.org/documentation/master/"

# Pipe to head for specific sections
pandoc -f html -t plain "https://ziglang.org/documentation/master/" | head -200

List Standard Library Contents

# List all std lib modules via Codeberg API
curl -sL "https://codeberg.org/api/v1/repos/ziglang/zig/contents/lib/std" | jq -r '.[].name'

# List subdirectory contents
curl -sL "https://codeberg.org/api/v1/repos/ziglang/zig/contents/lib/std/mem" | jq -r '.[].name'

Fetch zig.guide Content

# Landing page and navigation
pandoc -f html -t plain "https://zig.guide/"

Documentation Sources

Common Module Paths

Version-Specific Documentation

Replace master with version tag for stable releases:

# 0.14.0 release
curl -sL "https://codeberg.org/ziglang/zig/raw/tag/0.14.0/lib/std/log.zig"

# Language reference for specific version
pandoc -f html -t plain "https://ziglang.org/documentation/0.14.0/"

Searching Documentation

Search for specific function/type in std lib

# Search for function name across std lib
curl -sL "https://codeberg.org/ziglang/zig/raw/branch/master/lib/std/<module>.zig" | grep -A5 "pub fn <name>"

# Example: find allocator.create
curl -sL "https://codeberg.org/ziglang/zig/raw/branch/master/lib/std/mem/Allocator.zig" | grep -A10 "pub fn create"

Extract doc comments

# Module-level docs (//!)
curl -sL "https://codeberg.org/ziglang/zig/raw/branch/master/lib/std/log.zig" | grep "^//!"

# Function/type docs (///)
curl -sL "https://codeberg.org/ziglang/zig/raw/branch/master/lib/std/mem/Allocator.zig" | grep -B1 "pub fn" | grep "///"

Troubleshooting

Empty content from ziglang.org/documentation/master/std/:

• The std lib HTML docs are JavaScript-rendered; use raw Codeberg instead

pandoc fails:

• Some pages require JavaScript; fall back to curl + raw Codeberg
• Check URL is correct (no trailing slash issues)

Rate limiting on Codeberg API:

• Use codeberg.org raw URLs directly instead of API
• Cache frequently accessed content locally
