One of the developers who had worked on a similar tool had suggested I use cobra to build a command line interface.</p> <h2 id="code-size">Code size</h2> <p>I explained to him that I actually had a lot of experience with <a href="https://github.com/spf13/cobra">Cobra</a> and that I thought it was an excellent library with lots of great support for nested commands, it also <a href="https://github.com/spf13/cobra/blob/master/go.sum">had lots of transitive dependencies</a> (313 lines in the go.sum at the time of this post), and I&rsquo;ve discovered that it actually can bloat the size of the executable quite a bit. Therefore I had elected to use the standard library to build my command line flags. Admittedly, I&rsquo;ve had to do a lot more work to actually build my commandline interface, I did kept the executable size to under 4 mb for all platforms.</p>
