Tangram

# Tangram Tangram is a build system and package manager. - **TypeScript** makes writing builds easy with autocomplete and type checking. - **Sandboxing** ensures builds do not have unspecified dependencies. - **Lockfiles** covering all dependencies make builds reliable and reproducible. - **Bundles** package software with all their dependencies in isolation from the rest of your system. - **Rootless operation** makes it easy to install and use without elevated permissions. - **Content addressed storage** minimizes disk use and network transfer. - **Virtual filesystems** eliminate duplication on disk and download artifacts on demand. - **Cross compilation** makes it easy to build for any machine with no virtualization. - **Version constraints** allow you to precisely control the version of each dependency. - **Granular caching** delivers fast incremental builds shared between machines. - **Distributed execution** schedules builds on as many machines as possible. To get started, run the install script below, or download the [latest release](https://github.com/tangramdotdev/tangram/releases/latest) and add it to `$PATH`. ```sh curl -fsSL https://tangram.dev/install.sh | sh ``` Create a file at the root of your project called `tangram.ts` with the following content: ```ts export default () => tg.file("Hello, World!"); ``` Run `tg build`. ```sh $ tg build fil_01tvcqmbbf8dkkejz6y69ywvgfsh9gyn1xjweyb9zgv0sf4752446g $ tg cat fil_01tvcqmbbf8dkkejz6y69ywvgfsh9gyn1xjweyb9zgv0sf4752446g Hello, World! ``` ## As a build system Use Tangram to build your existing projects faster and more reliably. This example builds a Rust project with the native libraries it depends on. ```ts import openssl from "openssl"; import { cargo } from "rust"; import * as std from "std"; import source from "./packages/hello"; export default () => { return cargo.build({ env: std.env(openssl()), source, }); }; ``` Run `tg run` to build and run the program. ```sh $ tg run Hello, World! ``` ## As a package manager Use Tangram to build reproducible environments that start instantly. This example builds an environment that contains specific versions of `jq` and `ripgrep`. ```ts import jq from "jq"; import sqlite from "sqlite"; import * as std from "std"; export default () => std.env(jq(), ripgrep()); ``` Run `tg run -- sh` to build the environment and run a shell in it. ```sh $ tg run -- sh $ jq --version jq-1.7.1 $ sqlite3 --version 3.43.2 $ exit ```
