A Macro+Tool config for ultraedit for procesing blocks of text externally

(1/1)

mouser:
Here is the combination of MACRO and TOOL that i use to let me select a block of text in a file and process it by an external exe program, capture the output and paste it back replacing the originally selected text.
The key feature of this technique is that it allows you to use an easy undo to undo the change (Ctrl+Z) and preserves your place in the file after the operation.
The sample tool below runs the open source Astyle exe (C++ coder formatter) on the selected block, and is configured to implement whitesmith style c++ indentation (http://en.wikipedia.org/wiki/Indent_style#Whitesmiths_style), which i love.

DONT CHECK "CAPTURE OUTPUT" - this has the exe write output to a file.

if your exe outputs to stdout, then you should check "capture output" and modify the macro and remove the lines from the first Open to the subsequent Closefile.

Just out of curiosity I whippped up this Zeus Lua macro which performs the same task :)

--        Name: Astyle Macro
--      Author: Jussi Jumppanen
--    Language: Lua Macro
-- Description: A simple Lua macro that takes the currently selected
--              text, saves it to the c:\temp\astlye.tmp file, runs it
--              through the astyle.exe utility, then pastes the result
--              back into the cdocument.
--
--  How To Run: Save to style.lua in the zScript directory.
--
--              All Zeus macros can be run using the macro execute menu
--              item or they can be bound to the keyboard or can be
--              attached to the macro drop down or popup menus.
