Http://www.mdbbs.org/thread-28471-1-1.html This is a reference method when I learn Perl, I feel very good, share with you:
Each person has different learning methods. The following are some examples for your reference.
- If Perl is the first programming language you have learned, we recommend that you first read some programming basics, process control, logic, and design knowledge. _ Do you have any good Chinese books to introduce? _
- If you have learned other languages, you can start with learning the Perl syntax [: http://www.oreilly.com.cn/book.php? Bn = 7-5083-1113-2 Perl language entry], or from the Perl's own documentation. When you understand the Perl syntax, try the examples in the book and write some simple programs. Soon you will find that Perl is similar to the language you have learned before.
- If you are an experienced programmer, you may start by reading the program and trying to understand it. Although different languages have many similarities, you may be confused in many cases. We recommend that you at least first understand the basic syntax of Perl.
- An almost general method is to first learn documents or books, try the program example, try to modify, and then modify the error. Then, read the program, try the complex program, and repeat the above steps. Reading + practice is the best way to learn.
At the same time,
- Set a learning goal for yourself, why learning Perl, and what to do with Perl. Knowledge is learned in practice. Try to use Perl to write a message book, home album, and log analysis program. Do not plan to write a complex program for an online store as soon as possible. from an early stage, it is easier to see the progress of learning and inspire yourself to learn.
- Closed-door self-taught people often need to spend more effort to learn, and often take more detours. If you can participate in the Perl community when learning Perl, You can exchange experience with other Perl users for help. If you are good at English, you can visit websites such as perlmonks.org and have a lot of Perl experts.
Tips
If you do not know how to use a function, use the perldoc function name on the command line to check the Perl documentation. You can also replace the function name with the module name to view the module documentation. For example, perldoc LWP: Simple. If the English language is difficult, read Oreilly books.
No matter how short your program is, using use warnings and use strict can greatly help you find errors. Fortunately, klaus has translated a wonderful debugging article, Brian's omnipotent guide to Perl.
- The wisdom of asking questions and the ability to find answers
Many questions encountered at the beginning have been asked by others and may have been answered. Therefore, you must learn to use google or forum to search for your answers. When you encounter a problem, you can express the problem, read the relevant documentation, and try to write a program to solve it yourself. If there is no clue, I will try to ask a question in the forum or a user group. Generally, we are more willing to help those who have already studied their own problems, those who only need the answer are often ignored. Language learning is a process of self-repeat and trying. Do not rely on others' help. If you have time, you can look at the wisdom of asking questions to help you get help from others faster. The following 4 are JackyCheng's insights (from PerlChina Forum http://xrl.us/fz9e)
- I personally think that learning Perl is a lifelong task. To get started, first understand the basics of Perl basic syntax, operators, functions, control processes, and other languages. Then, after getting started, continue to develop as needed.
- Perl is a hodgedge of languages with many branches, so I suggest you determine what to do with Perl first. If you simply want to learn perl without specific purpose, it is difficult to integrate it too much during the getting-started process. You just need to know something that is not practical.
- The most important thing to learn about Perl is practice. Many things cannot be solved even by top experts, so they need to be diligent in practice. I personally think you should first understand the perl culture, so that you can add more love for perl.
- In addition, there is a famous saying in perl that "there are great ways to connect to Rome". Remember that there are more than one way to solve anything. Choose the one that best suits you and wish you success.
