Tree + PkgTree

Tree is a small C-based language runtime with a package manager runtime (pkgtree) that installs Tree package files into .tree/packages.

Build

WSL (recommended on Windows)

make wsl

Linux/native

make linux

Direct gcc build

With pkgtree runtime:

gcc -std=c11 -Wall -Wextra -O2 main.c pkgtree_runtime.c -lm -o tree

Without pkgtree runtime:

gcc -std=c11 -Wall -Wextra -O2 main.c -lm -o tree

Quick usage

Run a script:

./tree test_packages.tree

Run package manager script:

./tree pkgtree.tree

Package manager model

pkgtree_runtime.c supports two repo modes:

• Local repo directory (default): repo
• Remote repo URL (fallback): https://...

tree.pkg format (v2)

tree.pkg stores project dependencies and repo settings.

# tree.pkg v2
repo=repo
format=2
core,1.0
json,1.0

Rules:

• Lines starting with # are comments.
• repo= selects local directory path or remote URL.
• Dependency entries are name,version (or name@version).

Local repository layout

repo/
  MANIFEST.tree
  pkg/
    core@1.0.tree
    text@1.0.tree
    json@1.0.tree
    toml@1.0.tree
    fs@1.0.tree
    cli@1.0.tree
    data@1.0.tree
    project@1.0.tree
    net@1.0.tree
    mathx@1.0.tree
    build@1.0.tree

repo/MANIFEST.tree format (v2)

Tab-separated columns:

name<TAB>version<TAB>description<TAB>dependencies

• description: human-readable package summary.
• dependencies: ;-separated list of package@version values.

Example:

data	1.0	Data glue package that combines JSON and TOML	json@1.0;toml@1.0

Included showcase packages

• core: math/random helpers.
• text: string transform helpers.
• json: JSON wrapper helpers.
• toml: TOML wrapper helpers.
• fs: workspace path helpers.
• cli: argc/argv helpers.
• data: combines JSON + TOML handling.
• project: project metadata bootstrap.
• net: endpoint/url dictionary helper.
• mathx: extra math constants/helpers.
• build: build profile metadata helpers.

Notes

• pkgtree_install() validates local packages against repo/MANIFEST.tree.
• Installed packages are copied to .tree/packages/<name>/<version>/<name>@<version>.tree.
• tree.lock is rewritten after install with an installed package count.
