pylint-sonarjson-catlab 2.0.0

A PyLint plugin that can output to SonarQube-importable JSON

pylint-sonarjson-catlab

This project is a fork of pylint-sonarjson, which is not maintained anymore.

A PyLint plugin that can output to SonarQube-importable JSON with configurable issue severity, effort, and type.

This is useful because when importing PyLint's parsable output via SonarQube mechanism for third-party issues all the severities are set to MAJOR. With pylint-sonarjson-catlab you can configure the issue severity per PyLint message ID, and import that as generic JSON in SonarQube.

Usage

$ pylint \
    --load-plugins=pylint_sonarjson_catlab \
    --output-format=sonarjson \
    --sonar-rules=<msg_id>:<severity>[:<effort>[:<type>]],... \
    --sonar-default-severity=<severity> \
    --sonar-default-effort=<effort> \
    --sonar-default-type=<type> \
    --only-enable-sonar-rules=<y or n> \
    --halt-on-invalid-sonar-rules=<y or n> \
    [...]

The plugin provides a new option sonar-rules that can configure the severity, effort, and type of the issue as it would appear in SonarQube. The option takes a comma-separated list whose items are of the form <msg_id>:<severity>:<effort>:<type>. The effort and type are optional and may be omitted.

In addition, the default severity, effort, and type for messages that are not listed in sonar-rules can respectively be set with sonar-default-severity, sonar-default-effort, sonar-default-type. They default to MINOR, 5, and CODE_SMELL respectively.

Setting the option only-enable-sonar-rules to y disables all messages except for those specified in sonar-rules. It is equivalent to --disable=all --enable=<msg_id>,... where <msg_id>,... are the message IDs specified in sonar-rules. The default value of only-enable-sonar-rules is n.

Lastly, enabling the option halt-on-invalid-sonar-rules will cause the plugin to raise an exception when a rule given in sonar-rules does not exist in Pylint and halt. Disabling this option will instead only report the invalid rule on stderr but will otherwise ignore the invalid rule. The default value of halt-on-invalid-sonar-rules is y.`

For example:

$ pylint \
    --load-plugins=pylint_sonarjson_catlab \
    --output-format=sonarjson \
    --sonar-rules=C0114:INFO:10,C0328:MINOR:1 \
    my_file.py

Output:

{
    "issues": [
        {
            "engineId": "PYLINT",
            "ruleId": "C0114",
            "type": "CODE_SMELL",
            "primaryLocation": {
                "message": "Missing module docstring",
                "filePath": "my_file.py",
                "textRange": {
                    "startLine": 1,
                    "startColumn": 0
                }
            },
            "severity": "INFO",
            "effortMinutes": 10
        }
    ]
}

This output, when saved to a file, can be imported into SonarQube as follows:

$ sonar-scanner -Dsonar.externalIssuesReportPaths=<path_to_pylint_sonarjson_catlab_log>

Installation

pip install pylint-sonarjson_catlab

Configuration via pylintrc or pyproject.toml

Instead of via the command line, the plugin can be configured via a pylintrc file or via pyproject.toml, as described in the Pylint documentation. Here is an exampe pylintrc file, generated with the --generate-rcfile command line option:

[MAIN]

load-plugins=pylint_sonarjson_catlab


[REPORTS]

output-format=sonarjson


[SONARQUBE JSON OUTPUT]

# If enabled, an exception will be raised if a non-existing rule is given in
# --sonar-rules and the  plugin will halt. When disabled, non-existing rules
# will be reported on stderr but are otherwise ignored.
halt-on-invalid-sonar-rules=yes

# Only enable messages specified in --sonar-rules.
only-enable-sonar-rules=no

# Number of effort minutes for rules not specified in --sonar-rules.
sonar-default-effort=5

# Issue severity for rules not specified in --sonar-rules.
sonar-default-severity=MINOR

# Type of SonarQube issue for rules not specified in --sonar-rules.
sonar-default-type=CODE_SMELL

# Comma-separated list of rules, their severity, and the minutes of efforts to
# fix the issues. The syntax is <message id>:<severity>[:<effort
# minutes>[:<type>]].
sonar-rules=C0114:INFO:10,C0328:MINOR:1

Similar output for pyproject.toml can be generated with the --generate-toml-config command line option.
