<p>In this day and age, when everything has a graphical interface, does it still |
|
makes sense to add command line options to your application? In fact, it does.</p> |
|
<span id="continue-reading"></span> |
|
<p>When I mentioned the configuration file, you may have thought about using |
|
adding a default path for it and using the same file over and over.</p> |
|
<p>Well, that's not wrong, but what if you want to use a different configuration? |
|
Would you keep moving the original configuration file to another place, moving |
|
your configuration back and keep this back and forth? Keep both versions and |
|
just use a <a href="https://en.wikipedia.org/wiki/Symbolic_link">symbolic link</a> with |
|
the configuration filename pointing to the one you want?</p> |
|
<p>Why not add a command line option in which the user can select which |
|
configuration file should be loaded?</p> |
|
<p>This would make their life <em>and yours</em> easy.</p> |
|
<p>Also, be aware that, today, there may be libraries to handle command line in |
|
every language, which will help you build a good command line interface, along |
|
with standardizing it to have the same interface as other applications.</p> |
