# KIN [![Build Status](https://github.com/Serchinastico/Kin/actions/workflows/python-publish.yml/badge.svg)](https://github.com/Serchinastico/Kin/releases)

Kin is a minimalistic tool to check whether your project.pbxproj file is correct.

## What does it do?

Have you ever found yourself undoing a merge due to a broken Xcode build? Then Kin is your tool. It will parse your project configuration file and detect errors.

## How does it work?

Kin is just a syntax checker built with ANTLR 4 with a very thin layer to be usable from command line. On the fly syntax checking integration for text editors and IDEs is a work in progress (see the "Text editor/IDE integration" section below).

## Usage

Install Kin with your favorite python package manager. If you don't have one you can use [pipx](https://pypa.github.io/pipx/).

Using `pipx`

```
pipx install kin
```

Using `easy_install`

```
easy_install kin
```

Using Homebrew

```
brew install kin
```

Once installed, use Kin from your Xcode project directory. Kin will automatically detect where your project configuration is located and check whether it is correct.

```
$> kin
CORRECT
```

If there is an error in your configuration file, Kin will return the offending line and a short description of the problem found.

```
$> kin
ERROR: line 400:3 mismatched input ')' expecting 'inputPaths'
```

Optionally, you can provide the location of your project.pbxproj to Kin:

```
$> kin myProject/myProject.xcodeproj/project.pbxproj
CORRECT
```

## Text editor/IDE integration

The following text editor and IDE integration packages are available:

Emacs

- [flycheck-pbxproj](https://github.com/danielmartin/flycheck-pbxproj)

## Do you want to contribute?

Feel free to add any useful feature to Kin, we will be glad to improve it with your help.

Kin uses [ANTLR](https://www.antlr.org/) to build a parser for pbxproj files. ANLTR can be installed with the following command:

```bash
brew install antlr
```

There is a [Makefile](./Makefile) that defines commands to work with Kin locally.

- `make compile` - Compiles the grammar into an ANTLR parser. Run it every time you make changes to the `PBXProj.g4` file.
- `make install` - Installs a symlink of kin in your machine so that you can run it your local build.
- `make test` - Runs all tests.
- `make test_last` - It builds and installs kin and then runs it against the latest modified test file. This is usually your go-to command while working on kin.

Only the `PBXProj.g4` file needs to be committed, GitHub Actions will produce the compiled grammar files.
