Updated. Added support for strings. Error handling is changed.

There appears to be severe degradation on the time it takes to include a smath file, if that smath file contains a variable that is a string of length greater than 16.

Lets say I had two smath files as such

smathToInclude.sm
{
a:="some string of some length"
}

smathFile
{
include(smathToInclude.sm)
}

as the length of the string a increases so does the time it takes to include the file.

To test this, I created the following file.

smathFile
{
for b:=1 to 20 //do this 20 times to get a true sense of the include function time
c:=include(smathToInclude.sm)
}

And i changed the length of variable a to the following lengths, and got the following times

strlen TimeToInclude
10-.07
11-.07
12-.075
13-.085
14-.09
15-.095
16-.11
17-.169
20-.451
21-.74
22-1.16
23-1.851
24-2.841
25-4.519
30-49.0

It appears that string lengths above 16 chars is where the time to include shoots off the map - which makes me think the error has to be 16 bit representation.

Just letting you guys know,

Files to be used by include() do not typically reside in the document directory where they are used but at some central repository in a given installation. Candidates for such repositories might be the extensions/snippets or extensions/example directories in the settings directory as found by SettingsDirectory().

How about adapted versions of include() either with a second argument or (more convenient in the dynamic assistant) a special name like include("name.sm","examples" ) or example("name.sm" ) or include_example("name.sm" ) or whatever seems to be convenient?

Then we could use the extensions manager for distribution and download of such files. Would also be nice to have a mechanism to include the complete contents of extensions/snippets or whatever dedicated directory by default (source lib plugin).

Without using the include() function you get the same result?

EDIT: I have reproduced the problem. I can't advise something for now.

Updated. Now file is searched for in two stages (if absolute path not used):
1. In the folder: /extensions/
2. In the document directory folder.

So, if you want to include some example sheet you need to use this: include( "examples\example1.sm" ) =

EDIT: Definitions in areas not supported.

Could you please address this limitation?

Thank you!

Updated. Definitions in areas now supported and function works faster.

Updated. My fault. The algorithm was changed and I forgot about it.

A lot of discussion has taken place here so I post my bug report here too. Or shall I use the bugtracker system instead?

Include does not work for variables defined in programming environment like if or for, see the example below, bread is not accessible in testmaster.sm

This is a very elegant way for the above example. Thanks for showing me this. In cases where you have complex conditions and you want to define many variables in if statements it would not work. Also it does not work for loops for, while. That's why I will ask Andrey to implement this.

see feature request To implement an include() function able to handle dynamic definitions. Please vote!
