## Why?

I believe you are familiar with the huge zoo of various utilities for testing, checking code standards, linters etc.
It's really often the output of utilities is not supported in popular CI systems (TeamCity, GitHub, etc...).
I guess you are lucky if the utility saves the error report in the `junit.xml` format, because it works pretty fine with almost all modern dev software.

But... My experience tells me it's the exception rather than the rule.
For example, I really like the good old [phpmd](https://github.com/phpmd/phpmd) utility (perhaps you have another _right_ opinion about the benefits. At least, it's just an example).
It doesn't integrate well with TeamCity/PhpStorm/GitHub. Everytime I spend a lot of time looking for results in the logs. Though I really want to see instant and well-printed error report.

Therefore, I developed a converter that changes the report format for deep integration with CI systems and JetBrain IDEs.

Well... It may seem to you it's a useless thing, and _your favorite super tool_ works fine in TeamCity/PhpStorm. Just take a look at [the examples below](#examples).

## Requirements

- PHP 8.3 or higher
- Extensions: dom, simplexml, hash

## Installing

```shell
composer require jbzoo/ci-report-converter
php ./vendor/bin/ci-report-converter --help

# OR use phar file
wget https://github.com/JBZoo/CI-Report-Converter/releases/latest/download/ci-report-converter.phar
chmod +x ./ci-report-converter.phar
./ci-report-converter.phar --help

# OR just pull the Docker Image
docker run --rm jbzoo/ci-report-converter --help
```

## Using as GitHub Action

Action allows you to convert error reports to the [GitHub Annotations format](https://docs.github.com/en/actions/reference/workflow-commands-for-github-actions#setting-a-warning-message)
 * See [demo of error output](https://github.com/JBZoo/CI-Report-Converter/actions/workflows/gh-action.yml?query=is%3Asuccess)
 * To learn more [see different examples](.github/workflows/gh-action.yml)

```yaml
- uses: jbzoo/ci-report-converter@master # or see the specific version on releases page
  with:
    # File path with the original report format. If not set or empty, then the STDIN is used.
    # Required: true
    input-file: ./build/checkstyle.xml

# Source format. Available options: checkstyle, junit, phpmd-json, phpmnd, pmd-cpd, psalm-json
    # Default value: checkstyle
    # Required: true
    input-format: checkstyle

# Will exit with the code=1, if any violations are found.
    # Default value: no
    non-zero-code: yes

# File path with the result report format. If not set or empty, then the STDOUT is used.
    output-file: ./build/junit.xml

# Target format. Available options: gitlab-json, github-cli, junit, plain, tc-inspections, tc-tests
    # Default value: github-cli
    # Required: true
    output-format: junit

# If option is set, all absolute file paths will be converted to relative once.
    # Default value: .
    root-path: ./custom/project/path

# Set custom name of root group/suite (if it's possible).
    # Required: true
    suite-name: My Tests

```

### Example GitHub Action workflow
```yml
name: Linters

on:
  pull_request:
    branches:
      - "*"

jobs:
  linters:
    name: PHPcs
    runs-on: ubuntu-latest
    steps:
      - name: Checkout Code
        uses: actions/checkout@v4

- name: Setup PHP
        uses: shivammathur/setup-php@v2
        with:
          php-version: 8.2
          tools: composer

- name: Install Dependencies
        run: composer install

- name: PHP Code Sniffer
        run: ./vendor/bin/phpcs --report=checkstyle --standard=PSR12 -q ./src > ./build/phpcs-checkstyle.xml

- name: Converting checkstyle.xml to Github Annotations
        uses: jbzoo/ci-report-converter@master
        with:
          input-file: build/phpcs-checkstyle.xml

```

At the moment, converting of reports works with
  * Input Formats:
    * [checkstyle](tests/fixtures/origin/phpcs/codestyle.xml) - the most popular sort of error report. It works for [Phan](https://github.com/phan/phan), [PHPcs](https://github.com/PHPCSStandards/PHP_CodeSniffer) and others.
    * [junit](tests/fixtures/origin/phpunit/junit-simple.xml) - also it's really popular sort of error report. Usually, the format is used to display unit test results.
    * [phpmd-json](tests/fixtures/origin/phpmd/json.json) - the most detailed report of [PHPMD](https://github.com/phpmd/phpmd).
    * [phpmnd](tests/fixtures/origin/phpmnd/phpmnd.xml) - I know only [PHP Magic Numbers Detector](https://github.com/povils/phpmnd).
    * [psalm-json](tests/fixtures/origin/psalm/json.json) - the most detailed report of [Psalm](https://github.com/vimeo/psalm).
    * [pmd-cpd](tests/fixtures/origin/phpcpd/pmd-cpd.xml) - it's PMD-CPD XML format. An example of tool is [Copy/Paste Detector](https://github.com/sebastianbergmann/phpcpd).
  * Output Formats:
    * [gitlab-json](tests/fixtures/origin/phpstan/gitlab.json) - [GitLab Custom Report](https://docs.gitlab.com/ee/user/project/merge_requests/code_quality.html#implementing-a-custom-tool).
    * [junit](tests/fixtures/origin/phpunit/junit-simple.xml) - The most popular sort of reporting.
    * [tc-tests](tests/fixtures/test-cases/ConverterTeamCityTest/testJUnit.txt) - [Reporting Tests in TeamCity/PhpStorm/JetBrains](https://www.jetbrains.com/help/teamcity/service-messages.html#Reporting+Tests).
    * [tc-inspections](tests/fixtures/test-cases/ConverterTeamCityInspectionsTest) - [Reporting Inspections in TeamCity](https://www.jetbrains.com/help/teamcity/service-messages.html#Reporting+Inspections).

## Examples

### JetBrains IDE (IntelliJ IDEA, PhpStorm, WebStorm, etc)

One of the unique features of the tool is converting reports to a unit test format compatible with JetBrains IDE and TeamCity.
The following examples show how to use JetBrains IDE UI to display any kind of style issues.
Yeah, I know that the integration is not the cleanest, and it's not super beautiful. However, this code/screenshots demonstrate the usability of the approach.

![PHPcs in JetBrains PhpStorm](https://raw.githubusercontent.com/JBZoo/CI-Report-Converter/master/.github/assets/phpstorm-checkstyle.png)

**NOTE:** I believe that coding style issues have the same level of severity as any other sort of errors.
Therefore, I prefer to use the same workflow to check the quality of the code as I do with regular PHPUnit tests. It's like "just one click!"
Also, you will have the awesome bonus - navigating the project and gives the most detailed information about errors.

**The general idea is pretty simple:**
 - We take almost any utility for testing.
 - It saves report in the file or outputs error to StdOut as xml/json.
 - CI-Report-Converter changes the report format. It saves result somewhere or just outputs it in StdOut.
 - ???
 - Profit.

In the next example we will see how to integrate JetBrains IDE UI with Code Sniffer deeply. I use PHPcs just as example. This is the most popular linter in PHP.
However, the approach is independent of the programming language or unit testing framework.

```php
<?php declare(strict_types=1);

use PHPUnit\Framework\Assert;
use PHPUnit\Framework\TestCase;

/**
 * Here's an example based on PHPUnit and PhpStorm, but you are not limited to PHP language.
 * This is just an example to show the idea.
 * So you can use any sort language to integrate style tests with JetBrains IDE.
 */
class CheckStyleExamplesTest extends TestCase
{
    /**
     * The short example which uses pipe as way to pass error report.
     */
    public function testPipelineWay(): void
    {
        echo shell_exec(                       # Execute command via shell and return the complete output as a string.
            'php ./vendor/bin/phpcs' .         # Path to bin of third-party tool (PHP Code Sniffer is just example).
            ' --report=checkstyle' .           # Output format of PHPcs. ci-report-converter expects it by default as `--input-format` option.
            ' --standard=PSR12 -q ./src' .     # The custom tool options. For phpcs `-q` is important!
            ' | ' .                            # The pipe operator, it passes the output of one command as input to another. See https://en.wikipedia.org/wiki/Pipeline_(Unix)
            ' ./ci-report-converter.phar'      # The converter does all the magic. Look at help description ( --help) to lean more about options and default values.
        );

# Usually PHPUnit expects at least one assert in a test.
        # Otherwise, it may show useless warning messages. It depends on PHPUnit version and your configurations.
        # So, just in case, we make a fake assertion.
        Assert::assertTrue(true);
    }

/**
     * The super detailed example which uses files as way to pass error report.
     */
    public function testXmlFileWay(): void
    {
        shell_exec(                                     # Execute command via shell and return the complete output as a string.
            'php ./vendor/bin/phpcs' .                  # Path to bin of third-party tool (PHP Code Sniffer is just example).
            ' --report=checkstyle' .                    # Output format of PHPcs. CI-Report-Converter expects it by default as `--input-format` option.
            ' --report-file=./build/phpcs-report.xml' . # Save result of phpcs work in XML file in "checkstyle" format.
            ' --standard=PSR12 -q ./src' .              # The custom tool options. For phpcs `-q` is important!
            ' || true > /dev/null'                      # We don't expect any output of phpcs and ignore error exit codes.
                                                        # Lol, we are very self-confident. Actually, we need only XML file, that's it.
        );

// I've shown all the options explicitly just to add transparency.
        // In fact, this example does the same thing as the code above in `testPipelineWay()`.
        echo shell_exec(
            './ci-report-converter.phar' .              # The path to bin file of CI-Report-Converter. It depends of your installation way. See above.
            ' --input-format=checkstyle' .              # Source reporting format. Default value is "checkstyle".
            ' --input-file=./build/phpcs-report.xml' .  # Using prepared file on previous step as source.
