## Groovy & Jenkinsfile Linter, Formatter and Auto-fixer
***New: The [article about the story of npm-groovy-lint](https://nicolas.vuillamy.fr/a-groovy-journey-to-open-source-during-covid-19-npm-groovy-lint-8d88c7eecebc), and why you should dive in open-source community !***
Based on [CodeNarc](http://codenarc.github.io/CodeNarc/) , this out of the box package allows to **track groovy errors** and **correct a part of them**
- Use option **--format** to format & prettify source code
- Use option **--fix** to activate autofixing of fixable rules
Easy to integrate in a CI/CD process (Jenkins Pipeline,CircleCI...) to lint your groovy or Jenkinsfile at each build :)
You can also use this package in :
- [Visual Studio Code Groovy Lint extension](https://marketplace.visualstudio.com/items?itemName=NicolasVuillamy.vscode-groovy-lint)
- [Mega-Linter](https://nvuillam.github.io/mega-linter/) (can be used as GitHub Action, and lints all other languages and formats)
- [Docker Image](#other)
See [CHANGELOG](https://github.com/nvuillam/npm-groovy-lint/blob/master/CHANGELOG.md)
Any **question**, **problem** or **enhancement request** ? Ask [**here**](https://github.com/nvuillam/npm-groovy-lint/issues) :)
## Usage
```shell
npm-groovy-lint [OPTIONS] [FILES|PATH|PATTERN]
```
| Parameter | Type | Description |
|-------------------------|---------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| -o
--output | String | Output format (txt,json,sarif,html,xml), or path to a file with one of these extensions
Default: `txt`
Examples:
- `"txt"`
- `"json"`
- `"./logs/myLintResults.txt"`
- `"./logs/myLintResults.sarif"`
- `"./logs/myLintResults.html"`
- `"./logs/myLintResults.xml"`
Note: HTML and XML are directly from CodeNarc so using these formats will disable many npm-groovy-lint features |
| -l
--loglevel | String | Log level (error,warning or info)
Default: info |
| --failon | String | Defines the error level where CLI will fail (return code = 1). error,warning,info or none. Each failure level includes the more critical ones. |
| -c
--config | String | Custom path to [GroovyLint config file](#configuration), or preset config `recommended\|recommended-jenkinsfile\|all`
Default: Browse current directory to find `.groovylintrc.json\|js\|yml\|package.json` config file, or default npm-groovy-lint config if not defined.
Note: command-line arguments have priority on config file properties |
| --parse | Boolean | Try to compile the source code and return parse errors (since v5.7.0, default to true, use --no-parse to deactivate) |
| --format | Boolean | Format source code |
| --fix | Boolean | Automatically fix problems when possible
See [Auto-fixable rules](#auto-fixable-rules) |
| -x
--fixrules | String | Option for --fix argument: List of rule identifiers to fix (if not specified, all available fixes will be applied). See [Auto-fixable rules](#auto-fixable-rules)
Examples:
- `"SpaceBeforeClosingBrace,SpaceAfterClosingBrace,UnusedImport"`
- `"Indentation"`
|
| --nolintafter | Boolean | When format or fix is called, a new lint is performed after the fixes to update the returned error list. If you just want the updated source code and do not care about the error logs, use this parameter to improve performances |
| -r
--rulesets | String | [RuleSet file(s)](http://codenarc.github.io/CodeNarc/codenarc-creating-ruleset.html) to use for linting, if you do not want to use recommended rules or .groovylintrc.js defined rules.
If list of comma separated strings corresponding to CodeNarc rules, a RuleSet file will be dynamically generated Examples:
- `"./config/codenarc/RuleSet-Custom.groovy"`
- `"./path/to/my/ruleset/files"`
- `Indentation{"spacesPerIndentLevel":2,"severity":"warning"},UnnecessarySemicolon,UnnecessaryGString` |
| --rulesetsoverridetype | String | If list of rules sent in rulesets option, defines if they replace rules defined in .groovylintrc.json, or if they are appended
Values: `replaceConfig` (default), `appendConfig` |
| -s
--source | String | If path and files are not set, you can directly send the source code string to analyze |
| --verbose | Boolean | More outputs in console, including performed fixes |
| -i
--ignorepattern | String | Comma-separated list of Ant-style file patterns specifying files that must be ignored
Default: none
Example: `"**/test/*""` |
| --noserver | Boolean | npm-groovy-lint launches a microservice to avoid performance issues caused by loading java/groovy each time,that auto kills itself after 1h idle. Use this argument if you do not want to use this feature |
| --returnrules | Boolean | Return rules descriptions and URL if set |
| --javaexecutable | String | Override java executable to use
Default: java
Example: C:\\Program Files\\Java\\jdk1.8.0_144\\bin\\java.exe |
| --javaoptions | String | Override java options to use
Default: "-Xms256m,-Xmx2048m" |
| --insight | Boolean | npm-groovy-lint collects anonymous usage statistics using [amplitude](https://www.npmjs.com/package/amplitude), in order to make new improvements based on how users use this package.
Summary charts are available at [https://tinyurl.com/groovy-stats](https://tinyurl.com/groovy-stats).
Analytics obviously does not receive sensitive information like your code, as you can see in analytics.js.
If you want to enable anonymous usage statistics, use `--insight` option. |
| --codenarcargs | String | Use core CodeNarc arguments (all npm-groovy-lint arguments will be ignored)
Doc:
Example: `npm-groovy-lint --codenarcargs -basedir="lib/example" -rulesetfiles="file:lib/example/RuleSet-Groovy.groovy" -maxPriority1Violations=0 -report="xml:ReportTestCodenarc.xml` |

--files | String | (DEPRECATED) Comma-separated list of Ant-style file patterns specifying files that must be included.
Default: `"**/*.groovy,**/Jenkinsfile,**/*.gradle"`
Examples:
- `"**/Jenkinsfile"`

```
## Installation
```shell
npm install -g npm-groovy-lint
```
- If you have issues with v9, install previous version with `npm install -g [email protected]`
- Node.js >= 12 is required to run this package. If you can't upgrade, you can use [nvm](https://github.com/nvm-sh/nvm) to have [different node versions on your computer](https://www.sitepoint.com/quick-tip-multiple-versions-node-nvm/)
- If you do not have java 17 installed on your computer, npm-groovy-lint will install them for you, so the first run may be long.
## Configuration
Default rules definition ([`recommended`](https://github.com/nvuillam/npm-groovy-lint/blob/master/lib/.groovylintrc-recommended.json), based on [`all`](https://github.com/nvuillam/npm-groovy-lint/blob/master/lib/.groovylintrc-all.json) tracks a lot of errors, do not hesitate to ignore some of them (like NoDef ou RequiredVariableType) if they are too mean for your project.
Create a file named **.groovylintrc.json** in the current or any parent directory of where your files to analyze are located
- your-repo-root-folder
- src
- groovy
- mygroovyfile.groovy
- Jenkinsfile
- **.groovylintrc.json** *(do not forget the dot at the beginning of the file name)*
*If you are using [VsCode Groovy Lint extension](https://marketplace.visualstudio.com/items?itemName=NicolasVuillamy.vscode-groovy-lint), just use QuickFix **Ignore in all files** and it will generate groovylintrc.json file.*
### Format
- **extends**: Name of a base configuration ([`recommended`](https://github.com/nvuillam/npm-groovy-lint/blob/master/lib/.groovylintrc-recommended.json), [`recommended-jenkinsfile`](https://github.com/nvuillam/npm-groovy-lint/blob/master/lib/.groovylintrc-recommended-jenkinsfile.json), [`all`](https://github.com/nvuillam/npm-groovy-lint/blob/master/lib/.groovylintrc-all.json))
- **rules**: List of rules definition, following format `"RuleSection.RuleName": ruleParameters` or `"RuleName": ruleParameters`
- *RuleName*: any of the **[CodeNarc rules](https://codenarc.github.io/CodeNarc/codenarc-rule-index.html)**
- *ruleParameters*: can be just a severity override ( `"off"`, `"error"`, `"warning"`, `"info"` ) , or a property list :
- severity : off,error,warning,info
- enabled : true (default) or false
- any of the [rule advanced properties](https://codenarc.github.io/CodeNarc/codenarc-rule-index.html)
OR
- **codenarcRulesets**: Comma-separated string containing the list of `.xml` or `.groovy` CodeNarc RuleSet files (in case you already are a CodeNarc user and do not wish to switch to npm-groovy-lint config format)
### Examples
```json
{
"extends": "recommended",
"rules": {
"comments.ClassJavadoc": "off",
"formatting.Indentation": {
"spacesPerIndentLevel": 4,
"severity": "info"
},
"UnnecessaryReturnKeyword": "error"
}
}
```
```json
{
"extends": "recommended-jenkinsfile",
"rules": {
"CouldBeElvis": "off",
"CouldBeSwitchStatement": "off",
"VariableName": {
"severity": "info"
}
}
}
```
```json
{
"codenarcRulesets": "RuleSet-1.groovy,RuleSet-2.groovy"
}
```
## Disabling rules in source
You can disable rules directly by adding comment in file, using [eslint style](https://eslint.org/docs/user-guide/configuring#disabling-rules-with-inline-comments)
To temporarily disable rule warnings in your file, use block comments in the following format:
```groovy
/* groovylint-disable */
def variable = 1;
/* groovylint-enable */
```
You can also disable or enable warnings for specific rules:
```groovy
/* groovylint-disable NoDef, UnnecessarySemicolon */
def variable = 1;
/* groovylint-enable NoDef, UnnecessarySemicolon */
```
To disable rule warnings in an entire file, put a `/* groovylint-disable */` block comment at the top of the file:
```groovy
/* groovylint-disable */
def variable = 1;
```
You can also disable or enable specific rules for an entire file:
```groovy
/* groovylint-disable NoDef */
def variable = 1;
```
To disable all rules on a specific line, use a line or block comment in one of the following formats:
```groovy
def variable = 1; // groovylint-disable-line
// groovylint-disable-next-line
def variable = 1;
/* groovylint-disable-next-line */
def variable = 1;
def variable = 1; /* groovylint-disable-line */
```
To disable a specific rule on a specific line:
```groovy
def variable = 1; // groovylint-disable-line NoDef
// groovylint-disable-next-line NoDef
def variable = 1;
def variable = 1; /* groovylint-disable-line NoDef */
/* groovylint-disable-next-line NoDef */
def variable = 1;
```
To disable multiple rules on a specific line:
```groovy
def variable = 1; // groovylint-disable-line NoDef, UnnecessarySemicolon
// groovylint-disable-next-line NoDef, UnnecessarySemicolon
def variable = 1;
def variable = 1; /* groovylint-disable-line NoDef, UnnecessarySemicolon */
/* groovylint-disable-next-line NoDef, UnnecessarySemicolon */
def variable = 1;
```

## CI/CD
### Mega-Linter
Latest npm-groovy-lint version is **natively integrated** in [**Mega-Linter**](https://nvuillam.github.io/mega-linter/), that you can use as GitHub action or in other CI tools
This tool can also **automatically apply fixes** on Pull Request branches
### CircleCI
```yaml
# .circleci/config.yml
version: 2.1
jobs:
lint:
docker:
- image: nvuillam/npm-groovy-lint
steps:
- checkout
- run: |
npm-groovy-lint
workflows:
version: 2
"lint":
jobs:
- lint
```
### Jenkins
```groovy
node {
checkout scm
docker.image('nvuillam/npm-groovy-lint').inside {
sh 'npm-groovy-lint'
}
}
```
### Shell
Run with default settings
```shell
docker run --rm -u "$(id -u):$(id -g)" -w=/tmp -v "$PWD":/tmp nvuillam/npm-groovy-lint
```
Run with additional flags by simply appending them at after docker image name:
```shell
docker run --rm -u "$(id -u):$(id -g)" -w=/tmp -v "$PWD":/tmp nvuillam/npm-groovy-lint --failon warning --verbose
```
### Other
You can run npm-groovy-lint using its [official docker image](https://hub.docker.com/r/nvuillam/npm-groovy-lint)
## Use as module
You can import npm-groovy-lint into your NPM package and call lint & fix via module, using the same options than from npm-groovy-lint command line
Example
```shell
npm install npm-groovy-lint --save
```
```javascript
const NpmGroovyLint = require("npm-groovy-lint/lib/groovy-lint.js");
const fse = require("fs-extra");
const npmGroovyLintConfig = {
source: fse.readFileSync('./lib/example/SampleFile.groovy').toString(),
fix: true,
loglevel: 'warning',
output: 'none'
};
const linter = new NpmGroovyLint(npmGroovyLintConfig, {});
await linter.run();
console.log(JSON.stringify(linter.lintResult));
```
## Troubleshooting
If you have issues with MegaLinter, you can [report it on the repository](https://github.com/nvuillam/npm-groovy-lint/issues)
To help reproducing, you can access advanced logs using DEBUG env variables
Examples:
- `DEBUG=npm-groovy-lint npm-groovy-lint ....`
- `DEBUG=npm-groovy-lint,npm-groovy-lint-trace npm-groovy-lint ....`
If you want to see what happens in CodeNarc Server, you can clone the repo and run locally `npm server:run` before running npm-groovy-lint: you'll see the live logs of the to CodeNarc Server for npm-groovy-lint.
