# CHANGELOG
22

## v0.0.7 (2025-03-25)
4+

### Features
6+
7+
* Added new `check` mode with threshold support for CI integration
8+
* Added `--threshold` option to check mode for detecting excessive variable usage
9+
* Returns exit code 2 when variable hard usage exceeds specified threshold
10+
* Restructured code with ScopesTrait to improve maintainability
11+
312
### Bug fix
413

514
* The name of the file path information item in scopes mode is `file`, but I want to match it with `filename`, which is the name of the file path item in single mode.

### CI Integration with Check Mode
126+
127+
Use the check command with an optional threshold to analyze files and enforce variable usage standards in CI/CD pipelines:
128+
129+
```bash
130+
# Check files with default threshold (200)
131+
$ vendor/bin/php-variable-hard-usage check src/
132+
133+
# Check with custom threshold
134+
$ vendor/bin/php-variable-hard-usage check --threshold=500 src/ tests/
135+
136+
# Check specific files and directories
137+
$ vendor/bin/php-variable-hard-usage check --threshold=300 src/Command.php config/
138+
```
139+
140+
The check mode returns different exit codes based on the result:
141+
142+
* Exit code 0: Success - No analysis errors and no scopes exceeding the threshold
143+
* Exit code 1: Analysis failure - Errors occurred during file parsing or analysis
144+
* Exit code 2: Threshold exceeded - One or more scopes exceeded the specified variable hard usage threshold
145+
146+
The output includes the threshold used, result status, and a list of scopes that exceeded the threshold:
147+
148+
```json
149+
{
150+
"threshold": 500,
151+
"result": "failure",
152+
"scopes": [
153+
{
154+
"file": "src/Parse/VariableParser.php",
155+
"namespace": "Smeghead\\PhpVariableHardUsage\\Parse",
156+
"name": "VariableParser::collectParseResultPerFunctionLike",
157+
"variableHardUsage": 655
158+
},
159+
{
160+
"file": "src/Command/SingleCommand.php",
161+
"namespace": "Smeghead\\PhpVariableHardUsage\\Command",
162+
"name": "SingleCommand::execute",
163+
"variableHardUsage": 530
164+
}
165+
]
166+
}
167+
```
168+
169+
This mode is particularly useful for integrating the tool into your CI/CD pipeline to fail builds when variable usage exceeds acceptable thresholds.
