1. [LINUX] source files made executable instantly
Hi,
I thought I'd share this neat little prefix_macro for any of you who may
use my Object Euphoria editor (available on the Recent User
Contributions page on RDS web site).
-- insert in "elsif" clauses in function prefix_macro()
elsif equal(macro, "topline")then
if platform() = LINUX
addqueue(CONTROL_T & CR & ARROW_UP & "#!" & gentenv("EUDIR")
& "/bin/exu" & CR)
addqueue(ESCAPE & "w") -- save file
-- "file_name" is the sequence declared previously in
-- in the editor holding the name of the file currently
-- being edited - use as is:
system("chmod +x " & file_name, 0)
end if
Once the macro is installed in the editor save the amended editor file.
Now whenever your editing a file you can execute the macro
from any point in the file your editing thusly:
";topline " ( without the quotes of course - the space after the macro
triggers exectution of the macro) The macro call string (;topline ) is
immediately erased from the text.
The file you are editing has now been made executable under LINUX by
entering "./myprog.ex(u)" at the command line. Or it may be executed in
the same manner as a compiled executable if copied anywhere into the
path, such as "/home/ken/euphoria/bin/". For that matter you can
easily add a command to the "topline" macro to copy your executable file
into your path such as this:
system("cp " & file_name & " /home/ken/euphoria/bin/", 0)
Mike Nelson wrote the prefix_macro() function for me when I told him
I was working on an editor for Object Euphoria. It really is a
marvelous piece of work -as is everything Mike codes! Thanks again
Mike! :) :)
