prospector-html

HTML and JSON report generator from prospector and semgrep static analyzer tools JSON output. Handy when using with GitLab CI.

Synopsis

prospector

pip3 install prospector
pip3 install prospector2html
cd <python-project-sources-dir>
prospector --no-style-warnings --strictness medium --output-format json > prospector_report.json
prospector-html --input prospector_report.json
cat prospector-html-report.html

semgrep

pip3 install prospector2html
cd <project-sources-dir>
docker run --rm -v "${PWD}:/src" returntocorp/semgrep:latest semgrep scan --json --output semgrep-native-report.json --config=auto
prospector-html --input semgrep-native-report --output filtered-report.html --filter semgrep
cat filtered-report.html

GitLab CI SAST

pip3 install prospector2html
cd <project-sources-dir>
docker run --rm -v "${PWD}:/src" returntocorp/semgrep:latest semgrep ci --gitlab-sast --output gl-sast-report.json --config=auto
prospector-html --input gl-sast-report.json --output filtered-report.json --json --filter gitlab-sast
cat filtered-report.json

Message filtering

Sometimes it is necessary to filter analyzer results by content of the message, rather than filter-out the whole error class by it's suppression. For example prospector would always complains at usage of _meta member in Django projects.

In this case one could fileter such messages by specifing it in prospector-html config file. .prospector-html.yaml by default. See details in the source of sample config or use following example:

# cat .prospector-html.yaml
filter:
  message:
      # Filter by exact match
    - "Message to filter"
    - Oter message to filter
  message_re:
      # Regexps to filter
    - 'Exactly one space required after comma.*'
    - 'Exactly one space required before assignment.*'
