You can change the verbosity level <b>verbose_level</b> 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 :</p> <pre><code class="plaintext">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) </code></pre> <p>If the <b>-log</b> 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</b> tag is given, then the default verbose level is 7 (ie: outputting all of perlcc's output to STDERR).</p> <p>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.</p> </dd> <dt id="-log-<logname>"><a class="permalink" href="#-log-%3Clogname%3E">#</a><a id="log-logname"></a>-log <logname></dt> <dd> <p>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.</p> </dd> <dt id="-argv-<arguments>"><a class="permalink" href="#-argv-%3Carguments%3E">#</a><a id="argv-arguments"></a>-argv <arguments></dt> <dd> <p>In combination with '-run' or '-e', tells perlcc to run the resulting executable with the string <b>arguments</b> as @ARGV.</p> </dd> <dt id="-sav"><a class="permalink" href="#-sav">#</a><a id="sav"></a>-sav</dt> <dd> <p>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.</p> </dd> <dt id="-gen"><a class="permalink" href="#-gen">#</a><a id="gen"></a>-gen</dt> <dd> <p>Tells perlcc to only create the intermediate C code, and not compile the results. Does an implicit <b>-sav</b>, saving the C code rather than deleting it.</p> </dd> <dt id="-run"><a class="permalink" href="#-run">#</a><a id="run"></a>-run</dt> <dd> <p>Immediately run the perl code that has been generated. NOTE: IF YOU GIVE THE <b>-run</b> FLAG TO <b>perlcc</b>, THEN THE REST OF @ARGV WILL BE INTERPRETED AS ARGUMENTS TO THE PROGRAM THAT YOU ARE COMPILING.</p> </dd> <dt id="-prog"><a class="permalink" href="#-prog">#</a><a id="prog"></a>-prog</dt> <dd> <p>Indicate that the programs at the command line are programs, and should be compiled as such. <b>perlcc</b> will automatically determine files to be programs if they have <b>.p</b>, <b>.pl</b>, <b>.bat</b> extensions.</p> </dd> <dt id="-mod"><a class="permalink" href="#-mod">#</a><a id="mod"></a>-mod</dt> <dd> <p>Indicate that the programs at the command line are modules, and should be compiled as such. <b>perlcc</b> will automatically determine files to be modules if they have the extension <b>.pm</b>.</p> </dd> </dl> <h1 id="ENVIRONMENT"><a class="permalink" href="#ENVIRONMENT">#</a>ENVIRONMENT</h1> <p>Most of the work of <b>perlcc</b> 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</b> assumes that the extensions:</p> <p>.p$, .pl$, and .bat$</p> <p>indicate a perl program, and:</p> <p>.pm$</p> <p>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.</p> <p>To change the extensions which are programs, and which are modules, set the environmental variables:</p> <p>PERL_SCRIPT_EXT PERL_MODULE_EXT</p> <p>These two environmental variables take colon-separated, legal perl regular expressions, and are used by perlcc to decide which objects are which. For example:</p> <p>setenv PERL_SCRIPT_EXT '.prl$:.perl$' prompt% perlcc sample.perl</p> <p>will compile the script 'sample.perl' into the executable 'sample', and</p> <p>setenv PERL_MODULE_EXT '.perlmod$:.perlmodule$'</p> <p>prompt% perlcc sample.perlmod</p> <p>will compile the module 'sample.perlmod' into the shared object 'sample.so'</p> <p>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:</p> <p>setenv PERL_SCRIPT_EXT '\.\.\.\.\.'</p> <p>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.</p> <h1 id="FILES"><a class="permalink" href="#FILES">#</a>FILES</h1> <p>'perlcc' uses a temporary file when you use the <b>-e</b> 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$$.</p> <p>When you use '-run' and don't save your executable, the temporary executable is perlc$$</p> <h1 id="BUGS"><a class="permalink" href="#BUGS">#</a>BUGS</h1> <p>perlcc currently cannot compile shared objects on Win32. This should be fixed by perl5.005.</p> </div> <div id="footer"> <p>Perldoc Browser is maintained by Dan Book (<a href="https://metacpan.org/author/DBOOK">DBOOK</a>).
