Including the same variable multiple times

8 posts in this topic

My program has gotten quite long and so I decided it's better to separate into different files.

Each function relies on a window handle for the application I'm working with.

Right now, since it's just one big file, the window handle is declared at the top with global scope.

However since I'm separating them, each file will declare the window handle.

The main script (which contains the UI) will include all of these separate files, which means it will include the handle multiple times. Will this cause a problem? Is it undesirable to include the same variable multiple times?

Tsukihime,

My program has gotten quite long and so I decided it's better to separate into different files

Why? :huh2:

Look at the #Region/#EndRegion directives in SciTE - I am currently working on a 4422 line script condensed into 16 main regions (i.e. 16 lines) which I can expand as much or as little as I wish. Each of those regions is further divided into other regions - great discipline for writing structured code! :alien:

You might also want to search for SciTEHopper in the Example forum - a great help in navigating long scripts. ;)

Having separate files for related functions seems cleaner than having a massive file with everything grouped together though.

I initially designed the program as separate smaller tools before combining it all together for ease-of-use, but didn't think it would get too big.

But the region thing does make it cleaner than otherwise lol

Tsukihime,

Another thought - you could write the "related functions" as #include files. Then your initially declared Global variable would be available to them all. :huh2:

Oh, you mean if I did something like

#include "something"

global $somevar = 1

func_from_something()

Functions in "something" would still recognize $somevar?

As Melba23 says, simply use #include but don't forget to also use #include-once at top of each include file to keep it from being included more than once, just in case.

Tsukihime,

An #include file is literally inserted into the script at the point you place the #include directive. As far as the interpreter is concerned it becomes part of the script. Just make sure you declare your Global variable before you #include the file to prevent "undeclared variable" errorsd. ;)

Try it and see - but I would still keep it all together myself. :huh2:

Or better, place your glabal variable (if you really need it to be global) at the top the the included file where it belongs. Have a look at almost any standard include source file to see that.
