Codeigniter3: What are the core directories required?

I wish to use codeigniter NOT as a framework for building a site, but simply as a backend to handle some php stuff (eg. db in/out, image manipulation, file writing to the server).

In the default download of CodeIgniter3, there are 3 primary directories (application, system, and user_guide). Most of application is roughly empty, other than application/config; and user_guide is surely unnecessary.

So what parts of CodeIgniter3 are needed such that it is functionally complete?

TL;DR: All of it

If you want to use just a set of a framework's components, CodeIgniter is not the right pick.

Long answer:

In theory: it should be just system/core/

But most of that code assumes that you have constants defined in index.php, that you do have an "application" directory (containing "config/" and "views/errors/" subdirectories).

A lot of it also depends on language translations, for which the defaults are in system/language/, so you need that too.

Some badly written parts may also depend on a particular system/libraries/ or system/helpers/ component.

So while we started with just system/core/, you now need all of system/ and at least some of application/ (though that can be renamed to something else).

CodeIgniter has a monolithic architecture; it is simply not built in a way to allow you to do what you're asking for. And those are only a few kylobytes of files anyway - it's not 1980 and that's not a problem; unless you actually load the extra components that you don't use, they wouldn't get in the way.
