After fiddling around with another source code beautifier, I gave up and went back to my version of Jiri Babor's "tidy.ex". Works like a charm. The original file is backed-up to file_name&"~", a "tidied" version of the file is written to file_name&".tidy" which is then copied over the original file. If you don't want to risk your original file you can comment out the code that do that overwrites the input file.
include tidy.e -- add to ui_gtk.e -- -- append the following lines to the end of the add(runmenu, { ~~ createmenuitem("Test Run after Bind/Shroud/Translate", "RunTestRun", 0, run_testrun), -- add comma create(GtkSeparatorMenuItem), -- add line createmenuitem("Tidy Source Code", "RunStart") -- add line }) -- insert the following lines at the end -- of the RunStart function: elsif equal(lbl, "Run Terminal Emulator") then Run("$SHELL") -- insert elsif equal(lbl, "Tidy Source Code") then printf(1, "\n\n\t%s\n\n", {tidy(file_name)}) ------------------------------------------------- else crash("Unable to get menu label")
Here is the file, "tidy.e"
-- -- tidy.e 1.2 -- -- 2013-04-07 edit by Kenneth Rhodes -- wolfmanjacques@gmail.com -- -- tidy.e 1.2, derived from Jiri Babor's tidy.ex 1.0, -- is an include file, intended to be used -- with an editor written in euphoria such as ed.ex. -- It can also be called from the command_line by -- tidy.ex 1.2 -- -- usage: -- include tidy.e -- tidy(sequence filename) -- -- -- Changes from Jiri Babor's tidy.ex 1.0: -- -- Added support for "loop", "switch", "type", "ifdef" -- -- Dropped command_line code and wrapped the input/output -- code in the public function, "tidy(filename)". -- -- Added routine to automatically backup input/source file -- file with a DESTRUCTIVE copy of the input filename to: -- file & "~".
