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

Source	URL Pattern	Notes
Std lib source	`codeberg.org/ziglang/zig/raw/branch/master/lib/std/<path>`	Most reliable; includes doc comments
Language reference	`ziglang.org/documentation/master/`	Use pandoc; prose content
zig.guide	`zig.guide/`	Beginner-friendly; use pandoc
Codeberg API	`codeberg.org/api/v1/repos/ziglang/zig/contents/lib/std`	List directory contents

Common Module Paths

Module	Path
Allocator	`lib/std/mem/Allocator.zig`
ArrayList	`lib/std/array_list.zig`
HashMap	`lib/std/hash_map.zig`
StringHashMap	`lib/std/hash/map.zig`
File System	`lib/std/fs.zig`
File	`lib/std/fs/File.zig`
IO	`lib/std/Io.zig`
Logging	`lib/std/log.zig`
Testing	`lib/std/testing.zig`
Debug	`lib/std/debug.zig`
Heap	`lib/std/heap.zig`
Build System	`lib/std/Build.zig`
JSON	`lib/std/json.zig`
HTTP	`lib/std/http.zig`
Thread	`lib/std/Thread.zig`
Process	`lib/std/process.zig`

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
