Go programming language has taken the developer ecosystem by storm. Since it's creation in 2009, the language has seen tremendous global adoption by developers looking for a lightweight as well as expressive language suited for microservices architectures. It has been touted to be on a trajectory to become the next enterprise programming language.
It gives us great pleasure to announce support for Go on DeepSource. The Go analyzer is in beta right now, and we look forward to getting feedback from you to make it better.
The analyzer detects 120+ types of issues falling into the following categories — bug risks, anti-patterns, security vulnerabilities, performance issues, documentation coverage and style violations.
Here’s quick overview of some sample issues from each of these categories.
deferin infinite loops which will never execute
time.Tickin a leaky way
SIGSTOPthat can’t be trapped
defaultcase in switch statements
Analyzing Go code with DeepSource is straightforward. Just add a
.deepsource.toml file to the repository root to tell DeepSource which analyzers to run. The following example configuration will run go analysis continuously on all pull requests.
version = 1 test_patterns = [ "tests/*_test.go", "**/*_test.go" ] [[analyzers]] name = "go" enabled = true [analyzers.meta] import_path = "github.com/username/repository" [[analyzers]] name = "test-coverage" enabled = true
You can also track test coverage for your Go code. Post enabling test coverage analyzer (above step), use DeepSource CLI to report metrics from any CI systems.
# Run your tests and generate coverage report go test -coverprofile=coverage.out # Install 'deepsource CLI' curl https://deepsource.io/cli | sh # Set DEEPSOURCE_DSN env variable from repository settings page export DEEPSOURCE_DSN=https://email@example.com # Report coverage artifact to 'test-coverage' analyzer ./bin/deepsource report --analyzer test-coverage --key go --value-file ./coverage.out
