<h2>
Building the code
</h2>

I use [Bazel](https://bazel.build) as my build system of choice, with a
preliminary [configure](/configure) script to setup the build. I'm gradually
working towards a completely hermetic build, but for now there remains a couple
of dependencies on the host C++ toolchain and Python runtime.

This project can only be built on a modern version of Ubuntu Linux or macOS.
This is a requirement I inherit from my dependencies, which eschew Windows and
other Linux distros. Fortunately, you can use a
[Docker](https://www.docker.com/community-edition) image and follow the Ubuntu
instructions:
# Format: Automated Code Formatters

This package implements an opinionated, non-configurable enforcer of code style.

```sh
$ docker run -it ubuntu:18.04 /bin/bash
$ format <path ...>
```

If you have success building this project on other platforms, I'd love to hear
about it and accept patches.
This program enforces a consistent code style on files by modifying them in
place. If a path is a directory, all files inside it are formatted.

#### Ubuntu/MacOS instructions
Features:

Configure the build and answer the yes/no questions. The default answers should
be fine:
* Automated code styling of C/C++, Python, Java, SQL, JavaScript, HTML,
CSS, go, and JSON files.
* Support for `.formatignore` files to mark files to be excluded from
formatting. The syntax of ignore files is similar to `.gitignore`, e.g. a
list of patterns to match, including (recursive) glob expansion, and
patterns beginning with `!` are un-ignored.
* A `--pre_commit` mode which formats files that have been staged for commit,
and stages changes. The commit is rejected if a partially-staged file is
modified. Enforce the use of pre-commit mode (and add a "Signed off" footer
to commits) by running `--install_pre_commit_hook`.
* Persistent caching of "last modified" timestamps for files to minimize the
amount of work done.
* A process lock which prevents races when multiple formatters are launched
simultaneously.

```sh
$ ./configure
```
The type of formatting applied to a file is determined by its suffix. See
format --print_suffixes for a list of suffixes which are formatted.

Note that CUDA support requires CUDA to have been installed separately,
see the [TensorFlow build docs](https://www.tensorflow.org/install/) for
instructions. CUDA support has only been tested for Linux builds, not macOS or
Docker containers.
This program uses a filesystem cache to store various attributes such as a
database of file modified times. See `format --print_cache_path` to print the
path of the cache. Included in the cache is a file lock which prevents mulitple
instances of this program from modifying files at the same time, irrespective
of the files being formatted.

The configure process generates a `bootstrap.sh` script which will install the
required dependent packages. Since installing these packages will affect the
global state of your system, and may requires root access, inspect this script
carefully. Once you're happy to proceed, run it using:
## Setup

```sh
$ bash ./bootstrap.sh
```
### Requirements

Finally, we must set up the shell environment for running bazel. The file `.env`
is created by the configure process and must be sourced for every shell we want
to use bazel with:
1. Python >= 3.6.
1. sqlite

### Install

Download the latest binary from the [Releases page](https://github.com/ChrisCummins/format) and put it in your $PATH.

Or to build from source:

```sh
$ source $PWD/.env
$ bazel run -c opt //tools/format:install
```

Now build or test whatever bazel targets you'd like. Use `bazel query //...` to
list the available targets. E.g. to run the entire test suite, run:
## License

```bash
$ bazel test //...
```
