Re: Name lengths in C code

 Just a reminder--function names shouldn't exceed 31 characters. The C 
 standard doesn't guarantee anything past that...

Using this simplistic program I found two names greater than 31 chars.
I don't know if there are names not fitting the little regexp used here,
but of those that do, these:

$ perl namecheck.pl *.c
[35] PackFile_ConstTable_get_const_count
[33] PackFile_ConstTable_push_constant

are too long.


So, who's the windbag that wrote such long names? Hey, waitaminute,
I wrote those!

The names are unique in the first 31 chars. Are we OK, or do I need
to mangle the names? I could mangle them by doing one of the following:

  * PackFile_{SomeWords}_*    PackFile_SW_*

  * PackFile_{SomeWords}_*    PF_SW_*

I'd rather mangle all the names in the library a standard way than have
all but two written out fully and two not.

Your thoughts?

 use a better editor. :) in emacs i wrote a copy word function and in my
 perl mode it also grabs the leading sigil. then i can paste it easily
 and not worry about spelling.

For emacs users, meta-/ is even better.   Type the first few letters of 
the function name, then hit meta-/.  From the docs:

Documentation:
Expand previous word dynamically.

Expands to the most recent, preceding word for which this is a prefix.
If no suitable preceding word is found, words following point are
considered.  If still no suitable word is found, then look in the
buffers accepted by the function pointed out by variable
`dabbrev-friend-buffer-function'.

A positive prefix argument, N, says to take the Nth backward *distinct*
possibility.  A negative argument says search forward.

If the cursor has not moved from the end of the previous expansion and
no argument is given, replace the previously-made expansion
with the next possible expansion not yet tried.

You think that's bad?  You aren't guaranteed more than six characters,
case-insensitive for external identifiers.

I've been told that Oracle actually requires conformance to this
in their coding standards.  I'm very happy that I don't have to
write code for Orcale...
