Look at the "Filters and Scripts" section of BBEdit's User Manual.  Amongst 
other environment variables, BBEdit sets BB_DOC_NAME and BB_DOC_PATH. With 
those you can easily check for the existence of the counterpart header and 
if it doesn't exist create one with the appropriate include file guards.

If it was me, I would use Perl for the scripting language since that allows 
you to use the same regular expression as you would use in BBEdit to search 
for C function headers in your .c file(s). How easily that will be depends 
largely upon how clean or ugly you write C code. (Without testing it, I 
think you can reject static function headings using a negative 
lookahead/lookbehind on static in the function heading.) I don't know if it 
is still the case, but BBEdit at one time shipped with a C function header 
grep pattern in the find/search dialogs.  You could use that as a starting 
point to work up to a regular expression that will find just the function 
headings in a .c file that you need/want to generation function prototypes 
for. 

I also wouldn't get too fancy with the prototype updating. Todays machines 
have cycles to spare so just regenerate the whole header contents anew, 
compare old with new, and then replace the old with the new if there is a 
difference between the two. Exactly how fine grained the replacing needs to 
be depends upon how you structure your header files and what else (e.g., 
comments and other non-function declarations) you put in the files.

[Steve deRosier]

For the include file guards, I'd suggest either looking at the
Stationary or Clippings features. Both should easily do what you want
to varying degrees.

To be a bit less blunt than my previous response: What do you expect to 
happen?


Do you have C++ source code in the editor, and do you want to run the 
program that would be a result of this? Or do you have a C++ based 
compiled tool, and do you want to process the front document with said 
tool?


The fact that to C++ code is simple doesn't matter. #! supports 
scripts: text files that start with #! and follow on with an interpreter 
for the rest of the script. This tells BBEdit which tool to use to run 
the script. Compiled programs work differently, and cannot be placed in 
#!.


Create a wrapper script around the tool, and run it from there, just 
like any other tool. That assumes the second use case.

Well, close. #! is Unix convention for signaling the path to an
interpreter. If one happens to have a c++ interpreter, then so be it.

I don't know, there may well be a command line syntax to g++ instructing
it to compile and run the remainder of the file and discard the
generated intermediate and final executable after. Or as you say a
script wrapper could be created to do just that:

In the days of MPW and later in the very early days of BBEdit worksheets it was 
possible to include compile, link, and execute commands in the text file that 
was the C source code.

The # in #! was carefully selected to be treated as a comment in most source 
code syntax.

#!/usr/bin/tcsh   (Not needed in MPW which is csh all by itself)
#IFDEF nonsense   (Never defined anywhere!)
gcc myself -o $HOME/bin/somebinary  (or perhaps something in /tmp)
link . . .  (When in MPW)
somebinary
exit
#ENDIF
include ...
main;
print Hello World;
.
# all done



It was possible to execute such a text file just by giving its name or select 
and ENTER in a worksheet. Almost as simple as a deck of FORTRAN cards inserted 
in a card reader for load and go of old.

The technique is still possible for simple things but it sure would be better 
if BBEdit worksheets could once again be executable text files as opposed to 
XML plists.  I can no longer execute a worksheet from another worksheet and I 
miss it.

Re: C++ plugin?

[fschietteca...@gmail.com]

You might want to check this out:

http://developer.apple.com/legacy/mac/library/technotes/tn2005/tn2130.html

A handle is a pointer to a pointer, that's all. Handles were pretty
fundamental to the Mac OS prior to X but don't really make sense
anymore, and the tech note recommends you use malloc() and calloc(),
in fact NewHandle() and NewPtr() just maps to those.
