I had this idea already weeks ago, but now I had the time to realize it.
I had this idea already weeks ago, but now I had the time to realize it.
Now its far enough to be shown. It’s nothing ready or save, more a preview.
It’s free Gesture drawing.
It gets slower with more gestures saved, I don’t know where the maximum is.

‘Schleife’
Ah! So you can continue a ‘for’ inside another ‘for’…impressed. Didn’t know.
Good job.

< ![CDATA[
the name doesn’t matter, you can use any other name (beside reserved ones).
‘schleife’ just maens loop in german 😀
BTW: this works also with break

< ![CDATA[
when changing the itemID is that for the gesture shortcut we created?
]]>
< ![CDATA[
Curtis Sylvester Jr.
yes.
]]>
< ![CDATA[
then something is wrong because i created my shortcut, grabbed its ID and put it in the script. then i ran the script from [choose app shortcut here] (which flashed a notice for next drawing being saved), i went to draw my gesture to save and the same notice came up again…. this time taking about 5 minutes to shut up. the gesture never got saved

< ![CDATA[
I haven’t tried this script for a while, maybe it’s broken in the current version… My phone is broken ATM, I can’t try.
]]>
< ![CDATA[
I added it from the repository importer as the instructions say but when I swipe over it it says “At line 56: missing ; after for-loop condition”. How do I fix it? Also what is the proper way to change the itemID?
Edit: I added the script in the first comment & now I’m having the same problem as Curtis Sylvester Jr.​ What’s wrong?

bahrta sai
i could not reproduce the error. And honetly, I haven’t looked at this script for more than a year, I have no idea if it will work in the current version.
]]>
< ![CDATA[
bahrta sai​ do you have the latest version of repository importer?
If so, what your line 56 look like? 
]]>
< ![CDATA[
bahrta sai the script in the first comment is outdated. I am currently rebuilding this functionality from scratch as part of my MultiTool. Are you interested in testing it?
