# Go analysis support for CodeQL
|
|
|
|
|
|
|
|
|
|
This open-source repository contains the extractor, CodeQL libraries, and queries that power Go
|
2020-03-12 13:57:06 +03:00
|
|
|
support in [LGTM](https://lgtm.com) and the other CodeQL products that [GitHub](https://github.com)
|
|
|
|
|
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 [QL](https://help.semmle.com/QL) 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.

|
|
|
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
|
|
|
|
|
|
2020-05-29 08:38:23 +03:00
|
|
|
To analyze a Go codebase, either use the [CodeQL command-line
|
|
|
|
|
interface](https://help.semmle.com/codeql/codeql-cli.html) to create a database yourself, or
|
|
|
|
|
download a pre-built database from [LGTM.com](https://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](https://github.com/github/codeql-go/tree/lgtm.com) branch of this
|
|
|
|
|
repository corresponds to the version of the queries that is currently deployed on LGTM.com.
|
2020-08-07 18:49:57 +03:00
|
|
|
The [main](https://github.com/github/codeql-go/tree/main) branch may contain changes that
|
2019-11-08 15:14:43 +03:00
|
|
|
have not been deployed yet, so you may need to upgrade databases downloaded from LGTM.com before
|
|
|
|
|
running queries on them.
