Custom Expression Functions

Hi tomb23568765!

there is one workaround:

expressions can read a file, and grab data from this file, like this:

$.evalFile("~/Desktop/myFunctions.txt");

So, you can write an AEGP plugin that creates a "myFunctions.txt" file on your desktop, and fill it with anything you want, like:

function getThingamabob(num, question) {

if (num == 2 and question == 'yes') {

          return true;

     } else {

          return false;

     }

}

Then, your expression will look like this:

$.evalFile("~/Desktop/myFunctions.txt");

getThingamabob(2, 'yes')

Cheers,

François

Yes, that should be easily doable:

You just create an AEGP C++ plugin file that creates a command ID and a command hook, something like this:

    ERR(suites.CommandSuite1()->AEGP_GetUniqueCommand(&S_Commando_cmd));

    ERR(suites.CommandSuite1()->AEGP_InsertMenuCommand(S_Commando_cmd, sPluginName.c_str(), iMenu, iMenuPosition));

    ERR(suites.RegisterSuite5()->AEGP_RegisterCommandHook(aegp_plugin_id, AEGP_HP_BeforeAE, AEGP_Command_ALL, CommandHook, 0));

    ERR(suites.RegisterSuite5()->AEGP_RegisterDeathHook(aegp_plugin_id, DeathHook,    NULL));

    ERR(suites.RegisterSuite5()->AEGP_RegisterUpdateMenuHook(aegp_plugin_id, UpdateMenuHook, NULL));

    ERR(suites.RegisterSuite5()->AEGP_RegisterIdleHook(aegp_plugin_id, IdleHook, NULL));

You can then call your custom commands globally from the AE scripting engine by either searching for the name using app.findMenuCommandId() or by directly calling it with app.executeCommand().

Transferring parameters is also possible, at least I managed to get this working some years ago

Dang, that's a shame. Looks like I'll have to find some way to work around it.

to the best of my knowledge, it's not possible.

perhaps ZacLam​ would know better.
