extract

Given a Perl package Foo.pm, e.g. package Foo; use strict; sub bar { # some code here } sub baz { # more code here } 1; How can I write a script to extract the textual source code for each sub, resulting in a hash: $VAR1 = { 'bar' => 'sub bar { # some code here }', 'baz' => 'sub baz { # more code here }' }; I'd like to have the text exactly as it appears in the package, whitespace and all. Thanks. PPI is kind of a pain to work with at the very first; the documentation is not good at telling you which class documents which methods shown in the examples. But it works pretty well: use strict; use

Given URL of an archive (e.g. a zip file) Full name (including path) of a file inside that archive I'm looking for a way (preferably in Java) to create a local copy of that file, without downloading the entire archive first . From my (limited) understanding it should be possible, though I have no idea how to do that. I've been using TrueZip , since it seems to support a large variety of archive types, but I have doubts about its ability to work in such a way. Does anyone have any experience with that sort of thing? EDIT: being able to also do that with tarballs and zipped tarballs is also

I have an ASCII log file with some content I would like to extract. I've never taken time to learn Perl properly, but I figure this is a good tool for this task. The file is structured like this: ... ... some garbage ... ... garbage START what i want is on different lines END ... ... more garbage ... next one START more stuff I want, again spread through multiple lines END ... more garbage So, I'm looking for a way to extract the lines between each START and END delimiter strings. How can I do this? So far, I've only found some examples on how to print a line with the START string, or other

I have a function that get a ZIP file and extract it to a directory (I use DotNetZip library.) public void ExtractFileToDirectory(string zipFileName, string outputDirectory) { ZipFile zip = ZipFile.Read(zipFileName); Directory.CreateDirectory(outputDirectory); zip.ExtractAll(outputDirectory,ExtractExistingFileAction.OverwriteSilently); } My ZIP file contains multiple files and directories. But I want to extract only some of these files, not all of them. How can I make this work? Oded You need to test each ZipEntry to see if you want to extract it: public void ExtractFileToDirectory(string

I have an array like this: array (0 => array ( 'id' => '20110209172713', 'Date' => '2011-02-09', 'Weight' => '200', ), 1 => array ( 'id' => '20110209172747', 'Date' => '2011-02-09', 'Weight' => '180', ), 2 => array ( 'id' => '20110209172827', 'Date' => '2011-02-09', 'Weight' => '175', ), 3 => array ( 'id' => '20110211204433', 'Date' => '2011-02-11', 'Weight' => '195', ), ) I need to extract minimal and maximal Weight values. In this example $min_value = 175 $max_value = 200 Any help on how to do this ? Thank you ! Option 1. First you map the array to get those numbers (and not the full details
