Mining with Lua

1.

There is no direct matching mechanism between ^ and $in Lua, nor is it through *? To do the shortest match of *, we should use - to do the shortest match of *. To sum up, refer to the following code. It should be noted that in the pattern, I use the beginning and end () to get the index of these two places, so that I can judge whether it is at the beginning and end of the string (used to simulate ^ and $)

< pre t = "code" L = "Ruby" > functionmatch (s)
localpat = & 39; () (. -), ([%) a%d%p%s])()'< br />localpos1,cap1,cap2,pos2=string.match(s,pat)
ifpos1==nilorpos1~=1orpos2~=(#s+1)then
returnnil
end
returncap1,cap2
end

locala,b
a,b=match(' abcdefg,5')< br />print(a,b)
a,b=match(' abcdxfg,5')< br />print(a,b)
a,b=match(' av,,')< br />print(a,b)

I just had one this afternoon

3. Game is an area that is more easily recognized by most people. That's why

Lua can be widely used in more fields than games. After 0, almost no new non Lua code has been added. But most non professionals haven't even heard the name Lightroom. My feeling is. Version 3, because it fully conforms to Richard Gabriel's theory of how to be recognized. Lua is widely used in the game field, but it is the manifestation of lua's wide application in all fields. For example, 40% - 60% of Adobe Photoshop Lightroom is written by Lua

4. Love2d + Lua, go to the pit.

5. In the past, Lua was able to do what basic, FORTRAN, C, Pascal and other languages could do. With the extension, Lua can support the programming of graphical interface, web, game and so on. And because its bottom layer is developed with C, it also has very high performance, which is much higher than that of Python.

6. one million three hundred and thirty-eight thousand eight hundred and seventy

7. Generally write some scripts, or some plug-in programs
for example, the plug-ins in world of Warcraft are written in Lua.

8. There are many kinds of script languages. For example, our common command, CMD, can also be regarded as a kind of script. The script language you said should be the script of web application

the common ones are JavaScript, VBScript, Perl, PHP, Python and ruby

script language is characterized by simple syntax, which is usually saved in the form of text, and it does not need to be compiled into the target program, and it can be directly explained when it is called. This can be used as a criterion for judging scripting language, such as JavaScript. You just need to create a new HTML file in Notepad and add a script to it. When the browser opens the HTML file, it will naturally call JS script

in a word, you can write programs in Notepad without compiling environment. The target program is basically a scripting language.

9. Stop dreaming
friends
I've been running rings since level 65
it's 129 now
San Xiu 17.
jn119.jp baby
the equipment is not perfect
these are all money for running around and escorting
600 rings a week
studied for N years
there is no strange rule
only a little
run around 5:00 to 8:00 in the morning
it basically requires 2J medicine and summoner
this is my running experience
hope to help you.

10. This has nothing to do with Lua. You can't ask it like this
first of all, does the API of your game have the functions you mentioned, and what are the interfaces
