Everyone wants to be more productive. That's probably why you use Perl: to get more work done in less time with less work.
Productivity isn't all about saving time, though. Saving effort is even more important, whether you mean finding the information you want, automating away repeated tasks, or finding ways not to have to think about things that you do all the time. In some ways, this is the notion of relentless automation—finding every little niggling task that always interrupts your current project by being so annoying, difficult, cumbersome, or different and then hiding it behind an alias, a shell script, a process, or whatever.
Here are a few ideas for ways to make your programming life easier and more productive. Try them, enjoy your new sense of free time, and let yourself notice the new points of friction in your life. Then solve them, too!
Keep module documentation and distributions mere keystrokes away.
If Perl has only one advantage over other programming languages, it's the number of modules on the CPAN (http://www.cpan.org/) that solve so many problems effectively. That brings up a smaller problem, though—choosing an appropriate module for the job.
http://search.cpan.org/ helps, but if you visit the site many times a day, the steps to start a search through the web interface can become annoying. Fortunately, the Mozilla family of web browsers, including Mozilla Firefox, let you set up shortcuts that make browsing much easier. These shortcuts are just bookmarked URLs with substitutable sections and keywords, but they're very powerful and useful—almost command-line aliases ("Make the Most of Shell Aliases" [Hack #4]) for your browser.
Here are three of the most useful.
The first technique is to find the module you want. Normally, you could visit the CPAN search site, type the appropriate words in the box, submit the form, and browse through the results. That's too much work though!
Open the bookmark menu in your browser; this is Bookmarks→Manage Bookmarks in Mozilla Firefox. Create a new bookmark. For name, put
Search CPAN and for Keyword enter
cpan. In the Location box, type:
Figure 1-1 shows the completed dialog box. Press OK, then go back to the browser. Clear the location bar, then type
Acme and hit Enter. This will take you immediately to the first page of search results for modules with
Acme in their names.
If you know exactly the name of the
module you want, it's more convenient to jump straight to information about that module. Create a new bookmark named
Documentation, with the keyword of
cpod and the location:
Press OK, then type
cpod Test::Builder and press Enter. You'll see the latest version of the
This doesn't seem to work for POD-only modules, such as
Test::Tutorial. Also, beware that the case must match exactly.
Sometimes it's more valuable to find advice from other people about a module, especially when you may have uncovered a bug or something inexplicable in the documentation. The AnnoCPAN project (http://www.annocpan.org/) is a public site that allows users to annotate the documentation of any CPAN module. This is a good way to share your hard-won knowledge about a module with the world.
Create a new bookmark yet again, with a name of
AnnoCPAN Module Documentation and a keyword of
apod. Set the location to:
Save the bookmark, then type
GraphViz in the browser's location bar and press Enter. Scroll down a few pages and you should see notes on various paragraphs of the documentation.
The URL of the bookmark can be a
