github.phpd.cn/thought-machine/please@v12.2.0+incompatible/README.md (about) 1 # Please [![Build Status](https://circleci.com/gh/thought-machine/please.svg?style=shield)](https://circleci.com/gh/thought-machine/please) [![Go Report Card](https://goreportcard.com/badge/github.com/thought-machine/please)](https://goreportcard.com/report/github.com/thought-machine/please) 2 3 Please is a cross-language build system with an emphasis on 4 high performance, extensibility and reproduceability. 5 It supports a number of popular languages and can automate 6 nearly any aspect of your build process. 7 8 See http://please.build for more information. 9 10 Currently Linux (tested on Ubuntu) and OSX are actively supported, 11 and FreeBSD is known to work with a little setup (see FAQ for details). 12 13 14 Getting Started 15 =============== 16 17 The easiest way to install it on your own machine is to run: 18 ```bash 19 curl -s https://get.please.build | bash 20 ``` 21 Or, if you prefer, grab one of the tarballs off our 22 [releases page](https://github.com/thought-machine/please/releases) 23 and extract it yourself; it typically lives in `~/.please`. 24 25 Then you simply run `plz init` at the root of your project to set up 26 a default config and you're good to start adding BUILD files. 27 See [the website](http://please.build) for more instructions about 28 how to write them. 29 30 There are various commands available to interact with Please, the 31 most obvious & useful ones initially are `plz build` and `plz test` 32 to build things & run tests respectively. See `plz --help` or the 33 [documentation](https://please.build/commands.html) for more comprehensive 34 information. 35 36 37 Building Please 38 =============== 39 40 To build Please yourself, run `./bootstrap.sh` in the repo root. 41 This will set up the minimal environment needed to build Please, 42 build it once manually and then rebuild it again using itself. 43 You'll need to have Go 1.9+ installed to build Please although once 44 built it can target any version from 1.5+ onwards. 45 46 Optional dependencies for various tests include Python, Java, unittest++ 47 (`sudo apt-get install libunittest++-dev`), clang, gold and docker - none 48 of those are required to build components so their tests will be excluded 49 if they aren't available. 50 51 If you'd rather not worry about installing the dependencies, we provide 52 a prebuilt Docker image based on Ubuntu which is capable of building 53 the whole thing for you: 54 [`docker run -it thoughtmachine/please_ubuntu`](https://hub.docker.com/r/thoughtmachine/please_ubuntu) 55 56 57 Documentation 58 ============= 59 60 * [Quickstart](https://please.build/quickstart.html) 61 * [Commands & command-line arguments](https://please.build/commands.html) 62 * [Built-in rules](https://please.build/lexicon.html) 63 * [BUILD language reference](https://please.build/language.html) 64 * [Custom build rules](https://please.build/build_rules.html) 65 * [Config reference](https://please.build/config.html) 66 * [FAQ](https://please.build/faq.html) 67 68 69 Status 70 ====== 71 72 Please is released & we consider it stable; we follow [semver](https://semver.org) 73 for releases, so major versions indicate potentially breaking changes to the 74 BUILD language, command line or other behaviour. We try to minimise this where 75 possible. 76 77 We're very happy to accept pull requests & feature requests, and bugs if it's 78 not working for you. We don't always have time for everything since Please is 79 only part-time work for us, but we'll do our best.
