It is no secret that using JASS had a huge problem called World Editor's syntax checker that always failed at showing the actual error line and also liked to crash too much.
But Zoxc released a
world editor hack that succesfully replaces WE's syntax checker with
PJASS .
Also if you rename your "World editor.exe" into "World editor ORIGINAL.exe" and place this new WEHelper program in the wc3 folder then change its name into "World Editor.exe" you can easily add this ability permanently.
As a bonus it executes warcraft III in a window when using test map, It can also let you choose OpenGL for testmap.
This tool and future tools with similar functionality should be promoted as an standard among people that use JASS as it makes JASS much more friendly for new users.
