TRANSFORMING TEXT

Apply iconA StrongED window has on its smarticon-bar the apply icon. By SHIFT-dragging a RiscLua program onto it, the text in the window can be transformed. Alternatively, by CTRL-dragging onto it, a new StrongED window containing the transformed text will be opened. The RiscLua program must either be in a file of type Lua or else have its first line start with #!lua. The program - or script as the jargon has it - can read the contents of the StrongED window as if they were in a file whose pathname were given by the value of arg[1] . The output from the program, as produced by the print function, for example, is the transformed text.

The symbol # initiates a comment in RiscLua if it occurs as the first character on the first line.

If you do not have StrongED you can still transform textfiles with RiscLua scripts by using the Apply utility.
