isalpha
documentation:
Return value
Non-zero value if the character is an alphabetic character, zero otherwise.
You should be either checking for not equal to 0 instead of true, as its not necessarily guaranteed to be 1
~= true
, or removing the comparison entirely
Also make sure that your loop condition is < and not “& lt” without the space unless that’s a weird formatting issue
For more information, make sure to check the documentation for the standard library functions
Mainline freecad always annoyed me because it has messages that pop up and really frustrated me to no end
The realthunder fork suppresses a lot of the popups which made it a lot less annoying to work with
