http://www.shlomifish.org/me/blogs/ git tip: adding remotes to .git/config http://shlomif-tech.livejournal.com/61068.html <p> When working with the <a href="http://en.wikipedia.org/wiki/Git_%28software%29" rel="nofollow">git version control system</a> and editing <tt>.git/config</tt> to add a new remote, some people may be tempted to copy and change the <tt>origin</tt> remote that reads something like: </p> <pre> [remote "origin"] fetch = +refs/heads/*:refs/remotes/origin/* url = git@github.com:shlomif/perl.git </pre> <p> However, note that <tt>origin</tt> also appears at the <tt>fetch = </tt> and needs to be changed there as well, or else all the branches will be placed in <tt>remotes/origin</tt>. Maybe there's a better way to add a new remote using the <tt>git config</tt> commands. </p> <p> Otherwise, I should note that there doesn't seem to be a consensus among git users whether <tt>git pull --rebase</tt> is better than a simple <tt>git pull</tt>: the perl people told me to use <tt>--rebase</tt> and the Amarok people and someone on Freenode's <tt>##programming</tt> told me not to use it. Now I'm just confused. </p> Shlomi Fish ( shlomif@iglu.org.il ) git tip perl tech tech tip http://shlomif-tech.livejournal.com/61068.html http://shlomif-tech.livejournal.com/61068.html Sun, 22 Jan 2012 16:33:04 GMT Breaking the Perl Debugger for Fun and Profit http://blogs.perl.org/users/shlomi_fish/2011/12/breaking-the-perl-debugger-for-fun-and-profit.html Before I cover the main topic of this entry, here are some short news and action items: If you have not acted against SOPA - the proposed online blacklist/censorship bill, you should.

All-star legend Ran Eilam will talk to us (both beginners and experts) about Vim and how to fathom this incredible beast. I warn you, the first two lines in the audience will be damaged by Emacs flames. </p> </li> <li> <p> <b>A bunch of modules which made sense writing</b> - by Sawyer X: I'm going to cover some utility modules I've written, why they were written and when they are useful. At the end, you'll have to judge whether they were worth writing at all. There will be voting booths available! (We'll cover Algorithm::Diff::Callback, App::Genpass, Data::PowerSet::Hash and Module::Version.) </p> </li> <li> <p> <b>To upgrade or not to upgrade, Perl 5.6 vs. Perl 5.14</b> - ik vs. Sawyer X: A source of great concern in the Perl users community is whether to use an up-to-date Perl and what version should be considered "too old". On one hand, we have the management that wants as little cost and changes as possible (sometimes along with systems administrators), and on the other hand, the developer who wants to use the latest technologies, and is often stuck on obsolete systems. </p> <p> In light of this serious consideration, we're going to take turns poking at each other with a stick, wearing funny hats, damning the unbelievers and heretics until they submit to one side: 5.6 or 5.14! </p> </li> </ul> <p> The entrance to the meeting is free-of-charge, and everyone are welcome to attend.

As a result, I had to find a good JavaScript automated tests library to allow me to write automated tests for the code. I first looked at Test.More and Test.Harness from JSAN (the JavaScript Archive Network) but as it turned out, JSAN was defunct, and no one had time to mark it as such. Then I asked the “Test.Run” developer (another thing I had found on jsan) to instruct me how to get it up and running, and he gave me a link to its archive, which was 1.5 mb compressed (!), and so was not acceptable. </p> <p> I looked at <a href="http://en.wikipedia.org/wiki/list_of_unit_testing_frameworks#javascript" rel="nofollow">the Wikipedia list of unit testing frameworks</a>, but there were too many. at least I understood that jsUnit was no longer actively maintained. I looked at Jasmine, which is a bdd framework for JS, but its syntax seemed too horrid and unnatural. </p> <p> Eventually, I decided to ask for recommendation on <a href="http://stackoverflow.com/" rel="nofollow">Stack Overflow</a> and, as after I wrote my title, I found a <a href="http://stackoverflow.com/questions/96066/automated-unit-testing-with-javascript" rel="nofollow">a previous question</a>, where there was a recommendation of <a href="http://docs.jquery.com/Qunit" rel="nofollow">QUnit</a>, which I noticed was developed by the jQuery people, and as I'm fond of jQuery, I decided to look deeper into it. </p> <p> I wasn't disappointed by QUnit - it does what it does well, and I was able to write my test suite using it, so I can recommend it as well. It has primitives that are very similar to perl's <a href="http://search.cpan.org/perldoc?Test::More" rel="nofollow">Test::More</a>, and it can even assert that the number of assertions ran within a test are right (like Test::More can). </p> <p> So here's a tip for it: if you're writing your testing code in a different file, and you wish to check that no compile-time or run-time exception was thrown (which will cause qunit to report a success with zero assertions) you should wrap the testing code in a <tt>try { .. } catch</tt> block and in the catch block, run <tt>ok(false...)</tt>. </p> <p> Here's an example from my code: </p> <pre> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <title>ABCPath Test</title> <script src="jquery-latest.js"></script> <link rel="stylesheet" href="qunit.css" type="text/css" media="screen" /> <script type="text/javascript" src="qunit.js"></script> <script type="text/javascript" src="joose.mini.js"></script> <script type="text/javascript" src="abc-path.js"></script> <script type="text/javascript" src="abc-path-test.js"></script> <script type="text/javascript"> $(document).ready(function () { try { test_abc_path(); } catch (err) { module("Meta"); test("global_failure", function() { ok (false, 'test_abc_path() has thrown an exception or is invalid.'); }); } // Hide passed tests by default. $('#qunit-tests').addClass('hidepass'); }); </script> </head> <body> <h1 id="qunit-header">QUnit example</h1> <h2 id="qunit-banner"></h2> <div id="qunit-testrunner-toolbar"></div> <h2 id="qunit-userAgent"></h2> <ol id="qunit-tests"></ol> <div id="qunit-fixture">test markup, will be hidden</div> </body> </html> </pre> <p> Enjoy. </p> Shlomi Fish ( shlomif@iglu.org.il ) tip tech testing jquery tech tip perl qa javascript http://shlomif-tech.livejournal.com/59932.html http://shlomif-tech.livejournal.com/59932.html Mon, 05 Sep 2011 13:57:54 GMT Tel Aviv Perl Mongers Meeting on 31 August, 2011 http://shlomif-tech.livejournal.com/59692.html <p> (The Hebrew text will be followed by an English one). </p> <div align="right" dir="rtl"> <p> ב-31 באוגוסט 2011 (יום רביעי) נערוך את מפגש הפרל החודשי שלנו! אנו נפגשים ב-18:30 ומתחילים ב19:00. כתובת: מכללת שנקר, בניין מיטשל, רמת גן, חדר 2106.

I intend to teach it to you. (Sawyer - 40 minutes). </p> </li> <li> <p> <b>Gitflow</b> - Gitflow is a useful wrapper tool to allow you to set a more streamlined development process, taking into account features, releases, hot fixes and more. It's very useful when using multiple developers with an integrator, a QA, a dev team, and so on. I intend to showcase it as well!
