Code: Select all
function capture(cmd)
local f = assert(io.popen(cmd, 'r'))
local s = assert(f:read('*a'))
f:close()
return s

Thanks. I'll have to play around with that.A.Evseeva wrote: ↑Sat Jan 30, 2021 9:12 amIt can be done with:synthsin75 wrote: ↑Fri Jan 29, 2021 6:49 pm While it's easy enough to pass arguments from Moho Lua to external apps/scripts, it's not as easy to get data back.

out of curiosity - would the solution to that also allow icons in any tool to be updated (IOW, not that this example would actually be needed, but e.g. showing different icons for bezier in add point)synthsin75 wrote: ↑Thu Feb 11, 2021 5:45 am ...I've already solved a major usability problem and no longer need to restart Moho to update switch icons. ....
If you're using an ImageButton, yes. But if it's directly on the tool options, like the bezier button, (where it's not being invoked by a menu) it might require jumping to/from frame zero and back to get it to redraw.hayasidist wrote: ↑Thu Feb 11, 2021 9:01 amout of curiosity - would the solution to that also allow icons in any tool to be updated (IOW, not that this example would actually be needed, but e.g. showing different icons for bezier in add point)synthsin75 wrote: ↑Thu Feb 11, 2021 5:45 am ...I've already solved a major usability problem and no longer need to restart Moho to update switch icons. ....
ok! sounds really useful... looking forward to that as much if not more than the switch tool!!synthsin75 wrote: ↑Thu Feb 11, 2021 5:22 pmIf you're using an ImageButton, yes.

I haven't finished it yet. I've been busy with the beta and paid scripting work.
Ok, please figure out what do you need as a method getting something as args (a layer? or a bounding rectangle in layer space?) and returning something (bounding rectangle in pixels or what else... how it will be used?) and I'll try to help with it.synthsin75 wrote: ↑Mon May 10, 2021 7:23 pm So if anyone already has code to center a bounding box, by layer translation/scale or camera moves, that would help a ton.
I just need to center and zoom in on the content a layer (no matter the transforms of parent layers), so it fills the project dimensions. It doesn't matter how, as long as I can undo it after I render the button icons.A.Evseeva wrote: ↑Tue May 11, 2021 5:36 amOk, please figure out what do you need as a method getting something as args (a layer? or a bounding rectangle in layer space?) and returning something (bounding rectangle in pixels or what else... how it will be used?) and I'll try to help with it.synthsin75 wrote: ↑Mon May 10, 2021 7:23 pm So if anyone already has code to center a bounding box, by layer translation/scale or camera moves, that would help a ton.
