He’s often quoted me as saying “All frameworks suck”. Given that context, you might be surprised that I believe this book should be a good read. I have long been a critic of PHP frameworks for several reasons, one of which is the plethora of frameworks available. The chief advantage of using a framework is maintainability - frameworks provide a system and method for organizing code, but each framework is different, and if developers have to start from scratch with each new one then the advantage is lost. Having an official framework in the form of the Zend Framework means there is one framework likely to be well known and understood by a large number of devel- opers. With the support available from Zend, developers ought to be able to get up to speed easily. The engineers who have contributed to this framework have a deep understanding of the nuances of PHP and how to avoid the performance traps in- herent in building layers between PHP and your application. In other words, Zend Framework provides a great toolset for developers. As well as the MVC classes, the Zend Framework provides a set of really useful utility classes that can be integrated into any PHP application, regardless of how that application is architected. As such, there’s something to keep everyone happy. Cal has been preaching the Zend Framework at PHP conferences and in the De- vZone for some

  • Chapter 4 Programming in Perl
    Chapter 4 Programming in Perl 4.1 More on built-in functions in Perl There are many built-in functions in Perl, and even more are available as modules (see section 4.4) that can be downloaded from various Internet places. Some built-in functions have already been used in chapter 3.1 and some of these and some others will be described in more detail here. 4.1.1 split and join (+ qw, x operator, \here docs", .=) 1 #!/usr/bin/perl 2 3 $sequence = ">|SP:Q62671|RATTUS NORVEGICUS|"; 4 5 @parts = split '\|', $sequence; 6 for ( $i = 0; $i < @parts; $i++ ) { 7 print "Substring $i: $parts[$i]\n"; 8 } • split is used to split a string into an array of substrings. The program above will write out Substring 0: > Substring 1: SP:Q62671 Substring 2: RATTUS NORVEGICUS • The first argument of split specifies a regular expression, while the second is the string to be split. • The string is scanned for occurrences of the regexp which are taken to be the boundaries between the sub-strings. 57 58 CHAPTER 4. PROGRAMMING IN PERL • The parts of the string which are matched with the regexp are not included in the substrings. • Also empty substrings are extracted. Note, however that trailing empty strings are removed by default. • Note that the | character needs to be escaped in the example above, since it is a special character in a regexp. • split returns an array and since an array can be assigned to a list we can write: splitfasta.ply 1 #!/usr/bin/perl 2 3 $sequence=">|SP:Q62671|RATTUS NORVEGICUS|"; 4 5 ($marker, $code, $species) = split '\|', $sequence; 6 ($dummy, $acc) = split ':', $code; 7 print "This FastA sequence comes from the species $species\n"; 8 print "and has accession number $acc.\n"; splitfasta.ply • It is not uncommon that we want to write out long pieces of text using many print statements.

    Navigation • index • modules | • next | • previous | • Python v2.6.4 documentation » • The Python Standard Library » • 16. Generic Operating System Services » 16.5. getopt — Parser for command line options¶ This module helps scripts to parse the command line arguments in sys.argv. It supports the same conventions as the Unix getopt() function (including the special meanings of arguments of the form ‘-‘ and ‘--‘). Long options similar to those supported by GNU software may be used as well via an optional third argument. A more convenient, flexible, and powerful alternative is the optparse module. This module provides two functions and an exception: getopt.getopt(args, options[, long_options])¶ Parses command line options and parameter list. args is the argument list to be parsed, without the leading reference to the running program. Typically, this means sys.argv[1:]. options is the string of option letters that the script wants to recognize, with options that require an argument followed by a colon (':'; i.e., the same format that Unix getopt() uses). Note Unlike GNU getopt(), after a non-option argument, all further arguments are considered also non-options. This is similar to the way non-GNU Unix systems work. long_options, if specified, must be a list of strings with the names of the long options which should be supported. The leading '--' characters should not be included in the option name. Long options which require an argument should be followed by an equal sign ('='). Optional arguments are not supported. To accept only long options, options should be an empty string. Long options on the command line can be recognized so long as they provide a prefix of the option name that matches exactly one of the accepted options.

  • CLOPS: a DSL for Command Line Options
    CLOPS: A DSL for Command Line Options Mikol´aˇsJanota, Fintan Fairmichael, Viliam Holub, Radu Grigore, Julien Charles, Dermot Cochran, and Joseph R. Kiniry School of Computer Science and Informatics, Lero — The Irish Software Engineering Research Centre, and The Complex and Adaptive Systems Laboratory (CASL), University College Dublin, Ireland Abstract. Programmers often write custom parsers for the command line input of their programs. They do so, in part, because they believe that both their program’s parameterization and their option formats are simple. But as the program evolves, so does the parameterization and the available options. Gradually, option parsing, data structure complexity, and maintenance of related program documentation becomes unwieldy. This article introduces a novel DSL called CLOPS that lets a program- mer specify command line options and their complex inter-dependencies in a declarative fashion. The DSL is supported by a tool that gener- ates the following features to support command line option processing: (1) data structures to represent option values, (2) a command line parser that performs validity checks, and (3) command line documentation. We have exercised CLOPS by specifying the options of a small set of pro- grams like ls, gzip, and svn which have complex command line inter- faces. These examples are provided with the Open Source release of the CLOPS system. 1 Introduction A boiling frog is a well known phenomenon in software development. Just as a frog meets its fate in water that is slowly heated, so do software projects become unmanageable as their complexity gradually increases. Processing of command line options is not an exception.

  • Lisp, Jazz, Aikido Three Expressions of a Single Essence
    Lisp, Jazz, Aikido Three Expressions of a Single Essence Didier Vernaa a EPITA Research and Development Laboratory Abstract The relation between Science (what we can explain) and Art (what we can’t) has long been acknowledged and while every science contains an artistic part, every art form also needs a bit of science. Among all scientific disciplines, programming holds a special place for two reasons. First, the artistic part is not only undeniable but also essential. Second, and much like in a purely artistic discipline, the act of programming is driven partly by the notion of aesthetics: the pleasure we have in creating beautiful things. Even though the importance of aesthetics in the act of programming is now unquestioned, more could still be written on the subject. The field called “psychology of programming” focuses on the cognitive aspects ofthe activity, with the goal of improving the productivity of programmers. While many scientists have emphasized their concern for aesthetics and the impact it has on their activity, few computer scientists have actually written about their thought process while programming. What makes us like or dislike such and such language or paradigm? Why do we shape our programs the way we do? By answering these questions from the angle of aesthetics, we may be able to shed some new light on the art of programming. Starting from the assumption that aesthetics is an inherently transversal dimension, it should be possible for every programmer to find the same aesthetic driving force in every creative activity they undertake, not just programming, and in doing so, get deeper insight on why and how they do things the way they do.

  • Sample Chapter
    Spinellis main May 6, 2003 12:16 2 Basic Programming Elements What we observe is not nature itself, but nature exposed to our method of questioning. —Werner Heisenberg ode reading is in many cases a bottom-up activity. In this chapter we review the basic code elements that comprise programs and outline how to read and Creason about them. In Section 2.1 we dissect a simple program to demonstrate the type of reasoning necessary for code reading. We will also have the first oppor- tunity to identify common traps and pitfalls that we should watch for when reading or writing code, as well as idioms that can be useful for understanding its meaning. Sections 2.2 and onward build on our understanding by examining the functions, control structures, and expressions that make up a program. Again, we will reason about a specific program while at the same time examining the (common) control constructs of C, C++, Java, and Perl. Our first two complete examples are C programs mainly because realistic self-standing Java or C++ programs are orders of magni- tude larger. However, most of the concepts and structures we introduce here apply to programs written in any of the languages derived from C such as C++, C#, Java, Perl, and PHP. We end this chapter with a section detailing how to reason about a pro- gram’s flow of control at an abstract level, extracting semantic meaning out of its code elements. 2.1 A Complete Program A very simple yet useful program available on Unix systems is echo, which prints its arguments on the standard output (typically the screen).
