People occasionally ask for practical examples of macros when I lament the lack of macros in Perl.While I'm usually pleased at the degree to which Perl lets me design code to get and stay out of my way, sometimes its abstractions just aren't quite enough enough to remove all of the duplication available. (I've been refactoring one of our business projects in preparation for another round of.
Manipulating Word Documents with Perl. May 26, 2005 by Andrew Savikas In a recent lightning article, Customizing Emacs with Perl, Bob DuCharme explained how to use the Emacs shell-command-on-region function to invoke a Perl script on a marked region of text. Bob writes that he was reluctant to invest the time needed to write the elisp code needed for a particular string manipulation.So in our Perl code, we have to get the right reference, set up the module object, put the macro in a string, and then pass along the string to the module. Sounds confusing enough. (Aside: I ran the code in the VB6 link on a Win2K machine, and did not have to set the explicit reference to the Extensibility Library despite the instructions from the KB article.If you write Perl, or spend much time reading Perl, you will probably find it useful. Of course, if you simply follow the guidelines in perlstyle, you shouldn't need to reformat. The habit of formatting your code as you write it will help prevent bugs.
So, they tend to write scripts like they write “C” programs or any other RTL. But for ASIC engineers, knowledge of basic concepts of Perl helps to significantly increase the efficiency of Scripts. This inspired me to share the following “Top 10 tips” to write efficient Perl scripts in the world of ASIC. 1.
How to find a programming topic to write about. Mar 26, 2018 by David Farrell One thing I hear a lot when encouraging others to write about programming is “I don’t know what to write about”, and I agree it can hard to write anything when you’re not sure what to say.
Perl is one of the most powerful easy to use scripting language. It provides developers with lot of features and functionality. Writing in to Microsoft Excel is one of the most sought after functionality; excel being widely used to store data, across the globe. Here is a code snippet to help you write in to excel using perl.
Perl - Special Variables - There are some variables which have a predefined and special meaning in Perl. They are the variables that use punctuation characters after the usual variable in.

Write macros which directly call Perl functions. filepp comes with a module called function.pm which allows macros to be added which call Perl functions. This allows macros to have dynamic values. An example of how this works is the maths module maths.pm which has a macro add(a, b).
Perl inspiration; given the fact that OpenKore is written in Perl and many people who work on OpenKore project also write macros; The syntax was designed in order to make it easy to write a regexp-based interpreter; It was designed aiming to ease non-programmers' learning process.
This is in stark contrast to most other languages, where you are stuck with the syntax you're given, and infinitely more flexible than C's macros. Combined with Perl's powerful sparse-syntax operators, like map, grep, sort, and similar user-defined operators, I can almost always write complex algorithms more legibly and with less typing using.
The Perl Module output format is still experimental at the moment and could be changed in incompatible ways in future versions, although this should not be very probable. It is also lacking some features of other doxygen backends. However, it can be already used to generate useful output, as shown by the Perl Module-based generator.
Examples for using iMacros efficiently. All macros and scripts listed here are included in the default installation of iMacros Samples (unless otherwise noted). No vendor specific scripting language. iMacros does not use an awkward, proprietary vendor specific scripting language. The iMacros Browser, Internet Explorer (with iMacros for IE), Google Chrome (with iMacros Add-on) and Firefox.
Perl 5 was chosen to expand the list of open source programming languages that have been tested using the PVSStudio static code analyzer. This article is about found errors and difficulties when viewing analysis results. The number of macros in the code is.
Macros make common tasks easier. We use post-build and pre-build macros in Visual Studio. Two projects may rely on each other but remain separate. We write a macro to copy files from one project to another after the first one is built.
Name. Description. Interface. vi, vim. The granddaddy of Unix text editors, vi, is infamous for its difficult, non-intuitive command structure.On the bright side, vi is powerful, lightweight, and fast. Learning vi is a Unix rite of passage, since it is universally available on Unix-like systems. On most Linux distributions, an enhanced version of the traditional vi editor called vim is used.
