[Lua language from bronze to king] Part 2: development environment construction +3 editor usage examples

Preface

In the last chapter, we introduced lua The past and this life , Although I don't see many friends , At same time, there is no recommendation and no traffic ; Most people don't think there is any nutrition , In fact, I personally don't think so ：“ You like a language , Is it necessary to understand the origin of this language ; Why did the author create this language ？ Which pain diseases have been solved ？ Its own advantages and history ？”. At least through the translation of foreign languages to understand lua The past of language , I feel it is not easy along the way .

Java、Go、Python These popular languages are very popular , Of course! , I like them too . But I will also insist on using my spare time to record and practice about lua The article .

Lua The language supports the following systems

• Windows
• Linux
• Mac OS

linux Installation package download address ：lua Development package download address

windows Installation package download address ：windows Development package download address

mkdir: cannot create directory ‘/usr/local/man/man1’: File exists
make: *** [install] Error 1

##  explain 

 Obviously, it is not possible to create existing folders during installation , We can delete this existing folder   Carry on  make install

3、Window Installation on system Lua

①  Go to github On ：https://github.com/rjpcomputing/luaforwindows/releases  Download the corresponding version of lua Installation package 

②  Unzip to  D:\5.1

③  Configure environment variables ( Look at the picture below )

④  Input  Windows+R —–> cmd —-> lua 

⑤  Verify that the installation was successful ( Look at the picture below )

C:\Users\amumu>lua
Lua 5.1.5  Copyright (C) 1994-2012 Lua.org, PUC-Rio

Configure environment variables ：

Lua Language development editor selection

1、IDEA Editor tools ( With mac Computer as an example )

After successful installation , It is dark purple when opened ：

idea Editor

LUA The code prompts the plug-in address ：https://github.com/EmmyLua/IntelliJ-EmmyLua

2、VSCode Editor tools (Visual Studio Code)

Microsoft products , One runs on Mac OS、Windows and Linux Tools above , Powerful ,Lua There are countless language plug-ins , It can also support intelligent prompts , Compile, run and other functions .

Official download address ：https://code.visualstudio.com/

After successful installation, you can choose to install plug-ins that you think are good ：

Then write a quick lua Script running ：

local tonumber = tonumber

--  Define a table Array 
local _table = {' Hello everyone ！', ' I am amu children's shoes ！', ' You can search wechat official account ：', ' I'm amu ', '; Friends can pay attention to me ！'}

--  Loop iteration 
local text = ''
for i,v in ipairs(_table) do
   text = text..v
end

print(text) ###  Hello everyone ！ I am amu children's shoes ！ You can search wechat official account ： I'm amu ; Friends can pay attention to me ！

VSCode in “Terminal” -> New Terminal, perform lua hello.lua Command run directly hello.lua Script , give the result as follows ：

Running results

3、Sublime Text Editor tools

I used to write php、py The language has used this sublime Editor , It can be regarded as an artifact editor , A variety of fancy style highlighting plugins , Just like , Just can't put it down . The official can try it for free , But you can also find the cracked version on Baidu and Google .

Official download address ( It seems that you need to climb over the wall to visit )：https://www.sublimetext.com/

Official website of Chinese version ：[https://sublimetextcn.com/3/][https://sublimetextcn.com/3/]

After successful installation ; install Package Control Plug in tool center ：

• 1、 Keyboard press command + shift + p Call out Command input box
• 2、 Input install Package Control, Press enter
• 3、 After successful installation , The window will pop up , Just make sure
• 4、 Again using command + shift + p, Type... In the input box Install Package ( The first input needs to wait for the link , Seconds ) After success, the input box will appear again , Then enter the plug-in you want to install , Choose , enter , You can install the plug-in .

Write a lua Script , Execution depends on the result ：

--  Loop iteration 
local text = ' I hope my friends will pay more attention to ah mu ： Thank you for your good code , And followed me ！'

print(text) ###  I hope my friends will pay more attention to ah mu ： Thank you for your good code , And followed me ！

### command + B  function   Here's the picture 

Here we are ,Lua The language development environment has been set up ！

4、 Write our first lua Script program ( It comes from the love of our young people )

---  From the network C Written language 
--- lua Version as follows 
function show_love()
    local i, j, k, l, m
    local text = '' 
    --  Leave space at the beginning 5 That's ok 
     for i=1,5 do
        text = text .. "\n"
    end 
    --  front 3 There is a gap in the middle of the line to write 
    for i = 1, 3, 1 do
        --  Space on the left , There are fewer spaces to the left of each next line than the previous line 2 individual 8*n-2*i 
        for j = 1, 32-2*i do
            text = text.." "
        end
        
        --  Output small characters in the left half  
        for k = 1, 4 * i + 1 do
            text = text.."*"
        end
 
        --  The space in the middle , There are fewer spaces in each next line than in the previous line 4 individual  
        for l=1, 13-4*i do
            text = text.." "
        end
        
        --  Output small characters in the right half 
        for m=1,4*i+1 do
            text = text.."*"
        end

        --  After the output of each line, wrap the line  
        text = text.."\n"
    end

    --  Next 3 There is no space in the middle of the line 
    for i = 1, 3 do
        --  Space on the left  8*(n-1)+1
        for j=1,24+1 do
            text = text.." "
        end

        --  Output character small love 
        for k = 1, 29 do
            text = text.."*"
        end

        --  After the output of each line, wrap the line  
        text = text.."\n"
    end

    --  Next 7 That's ok 
    for i=7, 1, -1 do
    
        --  Space on the left , There are fewer spaces to the left of each next line than the previous line 2 individual  8*(n+1)-2*i
        for j=1,40-2*i do
            text = text.." "
        end

        --  There are fewer characters in each next line than in the previous line 4 individual 
        for k=1, 4*i-1 do
            text = text.."*"
        end

        --  After the output of each line, wrap the line  
        text = text.."\n"
    end
    
    --  The space to the left of the last line  
    for i=1,39 do
        text = text.." "
    end
    --  The last character is little love  
    text = text.."*\n"

    --  Finally vacate 5 That's ok  
    for i=1,5 do
        text = text.."\n"
    end
    
    return text
end

print(show_love())

The effect is as follows

                              *****         *****
                            *********     *********
