Cant get ST77xx <taskname>#length to work

[Affinite]

Im trying to centre a clock on a TFT using the example rules in ST77xx plugin notes
It doesnt work correctly and its because taskname>#length isnt working (for me).

I've simplified my rules below but I still only get value of 1 returned when I try to measure the length of the text string
Any ideas ?

Code: Select all

on displayhome do
  Touch,Setgrp,1
  tft,clear,black
  tft,txs,3
  let,121,[TFTpanel#length."text to measure"]
  let,122,[TFTpanel#width]              
  let,123,([TFTpanel#width]-[TFTpanel#length.%systm_hm%])/2      // (width - textlength)/2
  tft,txtfull,[int#123],100,3,red,black,%systm_hm%  // Display time red on black
endon

When I look at my system variables screen I see
%v121% = 1
%v122% = 480
%v123% = 240

I notice that in the rules editor "TFTpanel#length" is in black wheras "TFTpanel#width" is Red.
Does this mean the variable "TFTpanel#length" is inactive ?
I must have done something wrong - but I cant see it !

Well, congratulations!, you've actually found a tiny bug
You used the, documented, period as the separator between length and the value to take the length of, but during development we decided to change the separator there from the original comma to a period. That was changed where needed, except for the length and textheight subcommands...

I've fixed the code, that'll take some time to get merged and released, but for now you can change the period to a comma and it should work as expected.
Also fixed to return 0 when no text argument is provided, instead of a somewhat random value.

Thx ton
shame it doesnt work on the proportionately spaced fonts. The mono spaced fonts are pretty ugly
