chdirs - push/pop current working directory

chdirs is a package for managing the current working directory in a similar fashion to the unix shell pushd and popd functions.

Installation

> go get github.com/go-corelibs/chdirs@latest

Examples

Push, Pop

func main() {
    // need to do something in another directory
    // and ensure the program is returned to the
    // current working directory
    if err := chdirs.Push(".."); err != nil {
        panic(err)
    }
    defer chdirs.Pop()
    // do more stuff in the pushed directory...
    // the above defer will pop the path to the
    // original working directory when all is
    // done
}

MockBadWD, UnMockBadWD

// need to test important code when os.Getwd or filepath.Abs may fail,
// normally these tests are acceptably not written, however for command
// line programs where the current working directory could be anything,
// this testing is in fact quite necessary...

func Test(t *testing.T) {
    Convey("handling of os.Getwd/filepath.Abs errors", t, func() {
        err := MockBadWD()
        So(err, ShouldEqual, nil)
        /*
          ... test code handling os.Getwd and/or filepath.Abs errors ...
        */
        err = UnMockBadWD()
        So(err, ShouldEqual, nil)
    })
}
