go-errcheck provides an easy way to invoke errcheck from within Emacs.
It invokes errcheck with the current file's directory and optionally options for ignoring certain functions or packages. The output gets presented in a compilation buffer, allowing navigating errors.
Basic usage is as simple as invoking the function go-errcheck in a
Go buffer. Calling go-errcheck with a prefix argument allows setting
the ignorepkg and ignore flags interactively.
go-errcheck offers two customizable options: go-errcheck-ignorepkg
and go-errcheck-ignore, which correspondent to errcheck's flags. You
can set their default values directly or via the customization menu.
You can also use
file local variables
as well as
per-directory local variables.
Because errcheck always operates on whole directories/packages, using
per-directory variables might make more sense than using file local
variables. They allow setting the ignorepkg and ignore flags for
your packages so that errcheck will be invoked with them
automatically.
