Go analysis support for CodeQL
This open-source repository contains the extractor, CodeQL libraries, and queries that power Go
support in LGTM and the other CodeQL products that GitHub
makes available to its customers worldwide.
It contains two major components:
- an extractor, itself written in Go, that parses Go source code and converts it into a database
that can be queried using CodeQL. - static analysis libraries and queries written in CodeQL that can be
used to analyze such a database to find coding mistakes or security vulnerabilities.
The goal of this project is to provide comprehensive static analysis support for Go in CodeQL.
For the queries and libraries that power CodeQL support for other languages, visit the CodeQL
repository.
Installation
Clone this repository.
Run scripts/install-deps.sh. This will ensure that the necessary external CodeQL packs are
downloaded to your machine. You will need to re-run this script whenever you pull new commits from
the repo.
If you want to use the CodeQL extension for Visual Studio Code, import this repository into your VS
Code workspace.
Usage
To analyze a Go codebase, either use the CodeQL command-line
interface to create a database yourself, or
download a pre-built database from LGTM.com. You can then run any of the
queries contained in this repository either on the command line or using the VS Code extension.
Note that the lgtm.com branch of this
repository corresponds to the version of the queries that is currently deployed on LGTM.com.
The main branch may contain changes that
have not been deployed yet, so you may need to upgrade databases downloaded from LGTM.com before
running queries on them.
