718 | perlcc - frontend for perl compiler | |
719 | ||
720 | =head1 SYNOPSIS | |
721 | ||
722 | %prompt perlcc a.p # compiles into executable 'a' | |
723 | ||
724 | %prompt perlcc A.pm # compile into 'A.so' | |
725 | ||

727 | ||
728 | %prompt perlcc a.p -o execute -run # compiles 'a.p' into execute, runs on | |
729 | # the fly | |
730 | ||
731 | %prompt perlcc a.p -o execute -run -argv 'arg1 arg2 arg3' | |
732 | # compiles into execute, runs with | |
733 | # arg1 arg2 arg3 as @ARGV | |
734 | ||
735 | %prompt perlcc a.p b.p c.p -regex 's/\.p/\.exe' | |
736 | # compiles into 'a.exe','b.exe','c.exe'. | |
737 | ||
738 | %prompt perlcc a.p -log compilelog # compiles into 'a', saves compilation | |
739 | # info into compilelog, as well | |
740 | # as mirroring to screen | |
741 | ||
742 | %prompt perlcc a.p -log compilelog -verbose cdf | |
743 | # compiles into 'a', saves compilation | |
744 | # info into compilelog, being silent | |
745 | # on screen. | |
746 | ||
747 | %prompt perlcc a.p -C a.c -gen # generates C code (into a.c) and | |
748 | # stops without compile. | |
749 | ||
750 | %prompt perlcc a.p -L ../lib a.c | |
751 | # Compiles with the perl libraries | |
752 | # inside ../lib included. | |
753 | ||
754 | =head1 DESCRIPTION | |
755 | ||
756 | 'perlcc' is the frontend into the perl compiler. Typing 'perlcc a.p' | |
757 | compiles the code inside a.p into a standalone executable, and | |
758 | perlcc A.pm will compile into a shared object, A.so, suitable for inclusion | |
759 | into a perl program via "use A". | |
760 | ||
761 | There are quite a few flags to perlcc which help with such issues as compiling | |
762 | programs in bulk, testing compiled programs for compatibility with the | |
763 | interpreter, and controlling. | |
764 | ||
765 | =head1 OPTIONS | |
766 | ||
767 | =over 4 | |
768 | ||
769 | =item -L < library_directories > | |
770 | ||
771 | Adds directories in B<library_directories> to the compilation command. | |
772 | ||
773 | =item -I < include_directories > | |
774 | ||
775 | Adds directories inside B<include_directories> to the compilation command. | |
776 | ||
777 | =item -C < c_code_name > | |
778 | ||
779 | Explicitly gives the name B<c_code_name> to the generated c code which is to | |
780 | be compiled. Can only be used if compiling one file on the command line. | |
781 | ||
782 | =item -o < executable_name > | |
783 | ||
784 | Explicitly gives the name B<executable_name> to the executable which is to be | |
785 | compiled. Can only be used if compiling one file on the command line. | |
786 | ||
787 | =item -e < perl_line_to_execute> | |
788 | ||
789 | Compiles 'one liners', in the same way that B<perl -e> runs text strings at | |
790 | the command line. Default is to have the 'one liner' be compiled, and run all | |
791 | in one go (see B<-run>); giving the B<-o> flag saves the resultant executable, | |
792 | rather than throwing it away. Use '-argv' to pass arguments to the executable | |
793 | created. | |
794 | ||
795 | =item -regex <rename_regex> | |
796 | ||
797 | Gives a rule B<rename_regex> - which is a legal perl regular expression - to | |
798 | create executable file names. | |
799 | ||
800 | =item -verbose <verbose_level> | |
801 | ||
802 | Show exactly what steps perlcc is taking to compile your code. You can change | |
803 | the verbosity level B<verbose_level> much in the same way that the '-D' switch | |
804 | changes perl's debugging level, by giving either a number which is the sum of | |
805 | bits you want or a list of letters representing what you wish to see. Here are | |
806 | the verbosity levels so far : | |
807 | ||
808 | Bit 1(g): Code Generation Errors to STDERR | |
809 | Bit 2(a): Compilation Errors to STDERR | |
810 | Bit 4(t): Descriptive text to STDERR | |
811 | Bit 8(f): Code Generation Errors to file (B<-log> flag needed) | |
812 | Bit 16(c): Compilation Errors to file (B<-log> flag needed) | |
813 | Bit 32(d): Descriptive text to file (B<-log> flag needed) | |
814 | ||
815 | If the B<-log> tag is given, the default verbose level is 63 (ie: mirroring | |
816 | all of perlcc's output to both the screen and to a log file). If no B<-log> | |
817 | tag is given, then the default verbose level is 7 (ie: outputting all of | |
818 | perlcc's output to STDERR). | |
819 | ||
820 | NOTE: Because of buffering concerns, you CANNOT shadow the output of '-run' to | |
821 | both a file, and to the screen! Suggestions are welcome on how to overcome this | |
822 | difficulty, but for now it simply does not work properly, and hence will only go | |
823 | to the screen. | |
824 | ||
825 | =item -log <logname> | |
826 | ||
827 | Opens, for append, a logfile to save some or all of the text for a given | |
828 | compile command. No rewrite version is available, so this needs to be done | |
829 | manually. | |
830 | ||
831 | =item -argv <arguments> | |
832 | ||
833 | In combination with '-run' or '-e', tells perlcc to run the resulting | |
834 | executable with the string B<arguments> as @ARGV. | |
835 | ||
836 | =item -sav | |
837 | ||
838 | Tells perl to save the intermediate C code. Usually, this C code is the name | |
839 | of the perl code, plus '.c'; 'perlcode.p' gets generated in 'perlcode.p.c', | |
840 | for example. If used with the '-e' operator, you need to tell perlcc where to | |
841 | save resulting executables. | |
842 | ||
843 | =item -gen | |
844 | ||
845 | Tells perlcc to only create the intermediate C code, and not compile the | |
846 | results. Does an implicit B<-sav>, saving the C code rather than deleting it. | |
847 | ||
848 | =item -run | |
849 | ||
850 | Immediately run the perl code that has been generated. NOTE: IF YOU GIVE THE | |
851 | B<-run> FLAG TO B<perlcc>, THEN THE REST OF @ARGV WILL BE INTERPRETED AS | |
852 | ARGUMENTS TO THE PROGRAM THAT YOU ARE COMPILING. | |
853 | ||
854 | =item -prog | |
855 | ||
856 | Indicate that the programs at the command line are programs, and should be | |
857 | compiled as such. B<perlcc> will automatically determine files to be | |
858 | programs if they have B<.p>, B<.pl>, B<.bat> extensions. | |
859 | ||
860 | =item -mod | |
861 | ||
862 | Indicate that the programs at the command line are modules, and should be | |
863 | compiled as such. B<perlcc> will automatically determine files to be | |
864 | modules if they have the extension B<.pm>. | |
865 | ||
866 | =back | |
867 | ||
868 | =head1 ENVIRONMENT | |
869 | ||
870 | Most of the work of B<perlcc> is done at the command line. However, you can | |
871 | change the heuristic which determines what is a module and what is a program. | |
872 | As indicated above, B<perlcc> assumes that the extensions: | |
873 | ||
874 | .p$, .pl$, and .bat$ | |
875 | ||
876 | indicate a perl program, and: | |
877 | ||
878 | .pm$ | |
879 | ||
880 | indicate a library, for the purposes of creating executables. And furthermore, | |
881 | by default, these extensions will be replaced (and dropped ) in the process of | |
882 | creating an executable. | |
883 | ||
884 | To change the extensions which are programs, and which are modules, set the | |
885 | environmental variables: | |
886 | ||
887 | PERL_SCRIPT_EXT | |
888 | PERL_MODULE_EXT | |
889 | ||
890 | These two environmental variables take colon-separated, legal perl regular | |
891 | expressions, and are used by perlcc to decide which objects are which. | |
892 | For example: | |
893 | ||
894 | setenv PERL_SCRIPT_EXT '.prl$:.perl$' | |
895 | prompt% perlcc sample.perl | |
896 | ||
897 | will compile the script 'sample.perl' into the executable 'sample', and | |
898 | ||
899 | setenv PERL_MODULE_EXT '.perlmod$:.perlmodule$' | |
900 | ||
901 | prompt% perlcc sample.perlmod | |
902 | ||
903 | will compile the module 'sample.perlmod' into the shared object | |
904 | 'sample.so' | |
905 | ||
906 | NOTE: the '.' in the regular expressions for PERL_SCRIPT_EXT and PERL_MODULE_EXT | |
907 | is a literal '.', and not a wild-card. To get a true wild-card, you need to | |
908 | backslash the '.'; as in: | |
909 | ||
910 | setenv PERL_SCRIPT_EXT '\.\.\.\.\.' | |
911 | ||
912 | which would have the effect of compiling ANYTHING (except what is in | |
913 | PERL_MODULE_EXT) into an executable with 5 less characters in its name. | |
914 | ||
915 | =head1 FILES | |
916 | ||
917 | 'perlcc' uses a temporary file when you use the B<-e> option to evaluate | |
918 | text and compile it. This temporary file is 'perlc$$.p'. The temporary C code is | |
919 | perlc$$.p.c, and the temporary executable is perlc$$. | |
920 | ||
921 | When you use '-run' and don't save your executable, the temporary executable is | |
922 | perlc$$ | |
923 | ||
924 | =head1 BUGS | |
925 | ||
926 | perlcc currently cannot compile shared objects on Win32. This should be fixed | |
927 | by perl5.005. | |
