=head1 NAME
perlcc - frontend for perl compiler
=head1 SYNOPSIS
%prompt perlcc a.p # compiles into executable 'a'
%prompt perlcc A.pm # compile into 'A.so'
%prompt perlcc a.p -o execute # compiles 'a.p' into 'execute'.
%prompt perlcc a.p -o execute -run # compiles 'a.p' into execute, runs on
# the fly
%prompt perlcc a.p -o execute -run -argv 'arg1 arg2 arg3'
# compiles into execute, runs with
# arg1 arg2 arg3 as @ARGV
%prompt perlcc a.p b.p c.p -regex 's/\.p/\.exe'
# compiles into 'a.exe','b.exe','c.exe'.
%prompt perlcc a.p -log compilelog # compiles into 'a', saves compilation
# info into compilelog, as well
# as mirroring to screen
%prompt perlcc a.p -log compilelog -verbose cdf
# compiles into 'a', saves compilation
# info into compilelog, being silent
# on screen.
%prompt perlcc a.p -C a.c -gen # generates C code (into a.c) and
# stops without compile.
%prompt perlcc a.p -L ../lib a.c
# Compiles with the perl libraries
# inside ../lib included.
=head1 DESCRIPTION
'perlcc' is the frontend into the perl compiler. Typing 'perlcc a.p'
compiles the code inside a.p into a standalone executable, and
perlcc A.pm will compile into a shared object, A.so, suitable for inclusion
into a perl program via "use A".
There are quite a few flags to perlcc which help with such issues as compiling
programs in bulk, testing compiled programs for compatibility with the
interpreter, and controlling.
=head1 OPTIONS
=over 4
=item -L < library_directories >
Adds directories in B<library_directories> to the compilation command.
=item -I < include_directories >
Adds directories inside B<include_directories> to the compilation command.
=item -C < c_code_name >
Explicitly gives the name B<c_code_name> to the generated c code which is to
be compiled. Can only be used if compiling one file on the command line.
=item -o < executable_name >
Explicitly gives the name B<executable_name> to the executable which is to be
compiled. Can only be used if compiling one file on the command line.
=item -e < perl_line_to_execute>
Compiles 'one liners', in the same way that B<perl -e> runs text strings at
the command line. Default is to have the 'one liner' be compiled, and run all
in one go (see B<-run>); giving the B<-o> flag saves the resultant executable,
rather than throwing it away. Use '-argv' to pass arguments to the executable
created.
=item -regex <rename_regex>
Gives a rule B<rename_regex> - which is a legal perl regular expression - to
create executable file names.
=item -verbose <verbose_level>
Show exactly what steps perlcc is taking to compile your code. You can change
the verbosity level B<verbose_level> much in the same way that the '-D' switch
changes perl's debugging level, by giving either a number which is the sum of
bits you want or a list of letters representing what you wish to see. Here are
the verbosity levels so far :
Bit 1(g): Code Generation Errors to STDERR
Bit 2(a): Compilation Errors to STDERR
Bit 4(t): Descriptive text to STDERR
Bit 8(f): Code Generation Errors to file (B<-log> flag needed)
Bit 16(c): Compilation Errors to file (B<-log> flag needed)
Bit 32(d): Descriptive text to file (B<-log> flag needed)
If the B<-log> tag is given, the default verbose level is 63 (ie: mirroring
all of perlcc's output to both the screen and to a log file). If no B<-log>
tag is given, then the default verbose level is 7 (ie: outputting all of
perlcc's output to STDERR).
NOTE: Because of buffering concerns, you CANNOT shadow the output of '-run' to
both a file, and to the screen! Suggestions are welcome on how to overcome this
difficulty, but for now it simply does not work properly, and hence will only go
to the screen.
=item -log <logname>
Opens, for append, a logfile to save some or all of the text for a given
compile command. No rewrite version is available, so this needs to be done
manually.
=item -argv <arguments>
In combination with '-run' or '-e', tells perlcc to run the resulting
executable with the string B<arguments> as @ARGV.
=item -sav
Tells perl to save the intermediate C code. Usually, this C code is the name
of the perl code, plus '.c'; 'perlcode.p' gets generated in 'perlcode.p.c',
for example. If used with the '-e' operator, you need to tell perlcc where to
save resulting executables.
=item -gen
Tells perlcc to only create the intermediate C code, and not compile the
results. Does an implicit B<-sav>, saving the C code rather than deleting it.
=item -run
Immediately run the perl code that has been generated. NOTE: IF YOU GIVE THE
B<-run> FLAG TO B<perlcc>, THEN THE REST OF @ARGV WILL BE INTERPRETED AS
ARGUMENTS TO THE PROGRAM THAT YOU ARE COMPILING.
=item -prog
Indicate that the programs at the command line are programs, and should be
compiled as such. B<perlcc> will automatically determine files to be
programs if they have B<.p>, B<.pl>, B<.bat> extensions.
=item -mod
Indicate that the programs at the command line are modules, and should be
compiled as such. B<perlcc> will automatically determine files to be
modules if they have the extension B<.pm>.
=back
=head1 ENVIRONMENT
Most of the work of B<perlcc> is done at the command line. However, you can
change the heuristic which determines what is a module and what is a program.
As indicated above, B<perlcc> assumes that the extensions:
.p$, .pl$, and .bat$
indicate a perl program, and:
.pm$
indicate a library, for the purposes of creating executables. And furthermore,
by default, these extensions will be replaced (and dropped ) in the process of
creating an executable.
To change the extensions which are programs, and which are modules, set the
environmental variables:
PERL_SCRIPT_EXT
PERL_MODULE_EXT
These two environmental variables take colon-separated, legal perl regular
expressions, and are used by perlcc to decide which objects are which.
For example:
setenv PERL_SCRIPT_EXT '.prl$:.perl$'
prompt% perlcc sample.perl
will compile the script 'sample.perl' into the executable 'sample', and
setenv PERL_MODULE_EXT '.perlmod$:.perlmodule$'
prompt% perlcc sample.perlmod
will compile the module 'sample.perlmod' into the shared object
'sample.so'
NOTE: the '.' in the regular expressions for PERL_SCRIPT_EXT and PERL_MODULE_EXT
is a literal '.', and not a wild-card. To get a true wild-card, you need to
backslash the '.'; as in:
setenv PERL_SCRIPT_EXT '\.\.\.\.\.'
which would have the effect of compiling ANYTHING (except what is in
PERL_MODULE_EXT) into an executable with 5 less characters in its name.
=head1 FILES
'perlcc' uses a temporary file when you use the B<-e> option to evaluate
text and compile it. This temporary file is 'perlc$$.p'. The temporary C code is
perlc$$.p.c, and the temporary executable is perlc$$.
When you use '-run' and don't save your executable, the temporary executable is
perlc$$
=head1 BUGS
perlcc currently cannot compile shared objects on Win32. This should be fixed
by perl5.005.
