(07/07/09 05:38:28) Reply Quote More My Recent Posts	Tags : None Guys, I've been messing with Erlang on and off now for a few years, making progress slowly as time allows. One thing I've pondered for some time is scripting support. I would love to see a scripting interface incorporated into W3D that would allow users to extend the application by writing their own scripts. I've considered Python and Ruby primarily, but I'm put off by the added complexity of in creating those bindings and having to have the respective interpreters installed. Now I'm seeing REIA: http://wiki.reia-lang.org...eia_Programming_Language is coming along nicely. From those who are certainly more learned in Erlang and W3D than I, does this look like a possible answer to my question? One immediate adavatage I can see it that it wouldn't require any other script interpreters to be installed, a plus in my book. I know one can use the Erlang console, but I'd like to see something a bit more like using WISH in tcl/tk, or importing a script in Python or Ruby. My biggest question is due to lack of knowledge, can Erlang load and execute a script "on the fly"? Any thoughts? Last Edited By: jhouck 07/07/09 05:41:58. Edited 1 time.

Why not have the "script" just be nested LISTS of command that can be constructed and edited with the native Wings3D GUI/Dialogs ??? This should be fairly easy.

If I'm understanding you correctly, the user would still need some understanding of the underlying W3D API commands in order to know what commands to LIST. Years ago, I ran across a script interface for POVRay tha t used Python. A script would go something like this: Create a sphere called "ball"; The size of "ball" is 5,5,5; The color of "ball" is red; Move "ball" to 10,5,6; Create a pointlight called "beacon"; The color of "beacon" is white; Move "beacon" to 100,60, -34; There were a number of other simple commands to manipulate POVRay objects, lights, etc... "ball" and "beacon" are unique objects. They could be copied, deleted, etc. and it's subsequent copies called "ball_1", "ball_2" or some other convenient naming scheme. This is a more REXXish or LOGOish approach but more intuitive to use IMO. I can see an Erlang-based interpreter module would be needed to convert the "plain English" commands to equivalent Erlang/W3D components, but wouldn't this be a natural fit for Erlangs pattern matching and list comprehension? I'm just fishing for ideas... Cheers. Last Edited By: jhouck 07/07/09 11:34:18. Edited 1 times.

I for one would sure find some use for it.

(07/07/09 12:06:18) Reply Quote More My Recent Posts	I would suggest that the script plugin designer creates a list of eligible commands (elemental ones) which when run in sequence can create new and interesting results. So it would be more like just creating a structured list of current wings3D commands. Why not think simple first. Sometimes when you shoot for the stars ... one never gets off the launch-pad. Just shoot for the moon.

(07/07/09 12:20:02) Reply Quote More My Recent Posts	I dont understand nothing about programming, but i couldnt avoid to suggest (again) here (it sounds to me appropriate) a macro recorder. So users like me (the great part of w3d users, i suppose) can just record a sequence of procediments/operations and apply them to another selections/objects/situations... It is just what i can say into this programmers discussion: please try to think too about some kind of interface with non-programmers users. thanks for your attention.

(07/08/09 10:15:05) Wings Magician Reply Quote More My Recent Posts	Björn and I talked about this earlier today. My thoughts have always been to have a macro-recorder that stores the commands as erlang functions which can be edited by the user, loaded and interpreted. That would be an easy way in to programming erlang and wings plugins as well as useful for all wings users. Today it can't be done but with some changes in the wings-core it should be possible, but you will have to have some patience we have a lot of stuff we want to re-write change but not so much time. Macro's are pretty low on the priority list.

When you implement this, i'am sure this will be another great step at Wings3d development history. Thanks for the attention, dgud.

(07/09/09 18:19:29) Reply Quote More My Recent Posts	I'm sure: as soon as the devs come around to implement macros it will be done as excellent as all the rest of Wings. Not only recording and editing in the current session, but also the ability to save and load macros (Dan already said "loading"). And this will be done independent of existing key mappings but with command identifiers (some atoms) known by Wings, so that macros can be shared among users. Best regards
