It is also a supplement and summary to the 6th and 7th articles. It mainly talks about the principle and some applications of the so-called menu.ini extension production method. Thank you very much to the art director of Nanyuan BBS station. I'm sorry that I can't remember the ID in menu.ini. It inspired me to summarize this method from more perspectives and at a higher level. OK let's continue First, let’s talk about the interpretation process of menu.ini by firebird system. : This process is very simple. It is to use the foreground code to cover the background code and finally form the interface. There are two words in the above sentence that I would like to pay attention to. One is code. At this stage, all graphics Text control characters are processed in the form of codes. In other words, the system does not know that *[31m is to be displayed. The color is red, but I only know that it has 5 characters. Even the Chinese characters cannot be recognized, but I only know that it has two characters. One Chinese character has two characters. The reason why I emphasize this point is that the effect will be shown below. The second word is coverage. To put it figuratively speaking, the system first writes the background code on paper, and then writes the foreground code override without ever considering whether to break the background code itself Okay let's look at an example For example, the background code of this line is [abcdefghijkl] 0123456789012345678901234 This line is the abscissa ruler The corresponding foreground code is 10,7,0 test" "*[32m test *[0;1m" Note that here, all the code in the foreground will be overlaid to the corresponding position on the background intact. And on the background abcd...etc. will all be overwritten. Let’s look at a failed example. Below I will not give the foreground menu code but directly give the effect code. should be easier to understand foreground *[31m test *[0;1m Background *[31m test *[0;1m You can see that the code is the same, but the position is a little different. So what is the final code? Result *[31m test *[0;1mm The result is that there is an extra m at the end conversely if foreground *[31m test *[0;1m Background *[31m test *[0;1m Result **[31m test *[0;1m This result is more serious The difference is a little bigger foreground *[31m test *[0;1m Background *[31m test *[0;1m Result *[*[31m test *[0;1m This has caused confusion The above are all relatively failed examples. Let’s talk about how to rationally use this coverage effect to make our menu is more natural Method 1 Full background solution This solution is described in more detail in Chapter 6 of this tutorial and will not be repeated. : Advantages: It has great benefits in beautifying the interface. : Disadvantages: Menu cannot be differentiated based on permissions Method 2: All-prospective plan This solution is mentioned in Chapter 7 of this tutorial, but it is not explained in detail here. The implementation method is to use empty background or use all spaces or not load the background block in the menu at all. And all the menu content is added to the foreground block, for example !M EGROUP 10, 5, 0, "EGroup", "*[42m E Classified Discussion Forum *[0;1m !!!" Of course, there are menu options between the two ms, and the stuff after that is obviously the content of the background. Put it in the foreground statement : Advantages: It can provide a good solution to the problem of permission-differentiated menus that cannot be solved by the full-background solution. : Disadvantages: It can only control up to 14 lines. This is the upper and lower width of the general bbs background. Someone may have asked. The top and bottom width is only 14 lines. Isn’t it just right? How can this be considered a shortcoming? Here is a practical example. We hope to see such an effect. What people with ordinary permissions see is a b < Note that there are no menu options here anymore And what people with certain special permissions see is a b c < There are no menu options here either. This example cannot be achieved no matter which of the above solutions is adopted, so we will introduce the following Third option Solution 3 Background and foreground coverage solution It can be seen that the first and second options are two extreme options. Combine the two options. Naturally, better results can be achieved. Here, the concept of coverage introduced earlier will be used. Let’s first look at the solution to the above problem background The above two lines can also be empty This line must be prospect: !M EGROUP 10, 5, 0, "a", " a " !M EGROUP 0, 0, 0, "b", "*[42m b *[0;1m" !M EGROUP 0, 0, PERM SPECIAL4, "c", "*[43m c *[0;1m" In this way, the required effect can be achieved Why? Let's take a look at the code. The third line of the background has been preset to green. That is to say, if it does not appear Accidentally, there will be a green block here. Haha. When a person with PERM SPECIAL4 permissions comes An accident occurred. The system used c to overwrite the code in the background, so this position It is displayed according to the foreground code. This is just a very small example. In actual application, it will be more complicated. The foreground and background are clever. Cooperate so that it is normal to count every byte. The three options mentioned above each have their own uses and techniques. This does not mean that the third option Must be the best For the second option, please refer to the letter area of ​​Jinan Park. Ordinary users can see an envelope pattern on the right. The newly registered ID cannot be seen, but you can still see some other patterns. If you look closely, you can find that this is The full pattern removes the background of the option row that newly registered users cannot see. Both patterns are very Naturally, it can’t be seen that it was cropped. This is the clever choice of background pattern, arrangement of menu positions and applications. The effect caused by the 0,0 inheritance relationship of menu The above is just an introduction to the principles and some basic techniques of extended production methods. For these It takes more practice to master and apply it flexibly. I believe our menu will become more and more pp. Enjoy it! shipping 2003 01 13 @Fudan PS: All text comes from researching the menu works of BBS such as Huizhou Mingyue Bay and Ji Nanyuan and receiving zixiaBBS Thanks to all the prawns for their advice bow Source: Sun and Moon Guanghua bbs.fudan.edu.cn [FROM: 10.100.174.156]
