text editor, Groovy syntax highlighting
Currently it is impossible to edit Macro code within TXM with Groovy
syntax highlighting features.
The user must then edit code outside TXM.
Solution 1
Provide Groovy syntax highlighting.
Solution 2
Provide Groovy code-writing support services (including syntax highlighting).
