A getopt-like processor of command-line flags. It works much like the "flag" package, only it processes arguments in a way that is compatible with the getopt_long syntax, which is an extension of the syntax recommended by POSIX.
The example program named
example/example.go, is meant to be more
useful for someone trying to see how the package works. It comes with
a makefile demonstrating how to do some nice tricks, such as enabling
bash completion on your flags, and generating man pages and html
versions of the man page (see
the man page for the example program).
The test suite is the file
.test, which compiles and verifies the
output of the program in the
test-program directory, as well as the
example program. You can configure git to run the test suite
automatically by running the
Once the package is installed via goinstall, use the following to view the documentation:
# godoc --http=:6060
If you installed it from github, you will want to do this from the source directory:
# godoc --http=:6060 --path=.
This will run in the foreground, so do it in a terminal without anything important in it. Then you can go to http://localhost:6060/ and navigate via the package directory to the documentation or the left-hand navigation, depending on if it was goinstalled or run from a git clone.
