Wrapper script around golangci-lint to run on multiple platforms in parallel and have a unified output.

The script relies on the fact that each lint takes a single line and is always the same when reported on different platforms (which allows simply filtering duplicate lines to avoid duplicate warnings).

The wrapper can be used directly in an IDE since the output will be the same as golangci-lint. For example on VSCode it can be set as an Alternate Tools in the Go extension.

The time it takes to run is basically as long as the time of the time on the longest of each platform.

Arguments provided to the script are transfered as is to golangci-lint.

If not argument is provided, the default argument is just run.

Some arguments are added by the script when not provided by the user:

• out-format will be colored-line-number. Other meaningful values can be line-number, github-actions or tab, as they all print each lint on a single line, otherwise the final output would not be clear.
• print-issued-lines will be false, similarly so that each lint takes a single line and the final output is unified.
• allow-parallel-runners to enable running several instances of golangci-lint in parallel.

The list of platforms to run on can be provided using the PLATFORMS environment variable.

It should be a space-separated list of platforms, where each platform is an operating system and an architecture, separated by a slash.

The possible platforms are the ones supported by Go, which can be seen using the command go tool dist list.

If the PLATFORMS variable isn't defined or is empty, the following platforms will be used by default:

• linux/amd64
• linux/arm64
• darwin/amd64
• darwin/arm64
• windows/amd64
• windows/386

PLATFORMS="linux/amd64 linux/arm64 linux/386" golangci-lint-all run -c .golangci.yml --out-format=tab

In case of error from golangci-lint (eg. parsing / compiling) the output might not be clear.
