Extensions ?

Hi

I have been searching the wiki for a way to find out if an extension is loaded or not but I can't seem to find anything. Any help is welcome and I would appriciate alot.

The "Extension" command, which you use to load extensions in the first place, supports listing the loaded extensions.

Code: Select all

ext -list

Yes I understand that, but is it possible to check it in a script?

for ex. if [extenstion]...

Thanks

Code: Select all

if !${Extension[isxeq2](exists)}
{
  echo "ISXEQ2 is not loaded"
}

alternatively you could use ext -require to make the script abort if it is not loaded

you can also do it in preprocessor (this helps if you have global objects that would get initialized before main runs, but require the extension)

Code: Select all

#if !${Extension[isxeq2](exists)}
#error "ISXEQ2 is not loaded"
#endif

or you can do the equivalent of ext -require in preprocessor

Code: Select all

#if !${InnerSpace:LoadExtension[isxeq2](exists)}
#error "ISXEQ2 is not and could not be loaded"
#endif
