package coverage

// This package contains support routines for coverage "fixup" in the
// compiler, which happens when compiling a package whose source code
// has been run through "cmd/cover" to add instrumentation. The two
// important entry points are FixupVars (called prior to package init
// generation) and FixupInit (called following package init
// generation).

// BuildActionCoverMetaFile locates and returns the path of the
// meta-data file written by the "go tool cover" step as part of the
// build action for the "go test -cover" run action 'runAct'. Note
// that if the package has no functions the meta-data file will exist
// but will be empty; in this case the return is an empty string.

# Use of this source code is governed by a BSD-style
# license that can be found in the LICENSE file.

# A quick and dirty way to obtain code coverage from rulegen's main func. For
# example:
#
#     ./cover.bash && go tool cover -html=cover.out
#
# This script is needed to set up a temporary test file, so that we don't break
# regular 'go run .' usage to run the generator.
