From b288fc77b2108c5d86fce745204ca526113e46ed Mon Sep 17 00:00:00 2001 From: Jason Hall Date: Sat, 7 Jun 2025 00:14:39 -0400 Subject: [PATCH] Fix parser to handle multi-line JSON format and add local testing MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit fixes the parser to handle both JSON lines and multi-line JSON formats from govulncheck, and adds tools for local testing: - Updated parser to detect and handle both JSON lines and pretty-printed JSON - Added logic to skip govulncheck installation if already present - Created run-local.js for testing the action locally without GitHub Actions - Added test:local npm script for easy local testing - Changed example to use a version of golang.org/x/net with known vulnerabilities The parser now correctly identifies 14 vulnerabilities in the example, including ones that trace to the html.Parse call in main.go. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- dist/index.js | 60 +++++++++++++++++++++++++++------- example/go.mod | 4 +-- example/go.sum | 4 +-- lib/govulncheck.js | 10 +++++- lib/parser.js | 50 ++++++++++++++++++++++------ package.json | 3 +- run-local.js | 81 ++++++++++++++++++++++++++++++++++++++++++++++ test-local.js | 55 +++++++++++++++++++++++++++++++ 8 files changed, 240 insertions(+), 27 deletions(-) create mode 100755 run-local.js create mode 100755 test-local.js diff --git a/dist/index.js b/dist/index.js index 7ff9ce7..2d1ea2f 100644 --- a/dist/index.js +++ b/dist/index.js @@ -190,7 +190,15 @@ class GovulncheckRunner { } async install() { - await this.exec.exec('go', ['install', 'golang.org/x/vuln/cmd/govulncheck@latest']);
