Zig examples ⬆

Directory examples\ contains Zig code examples coming from various websites - mostly from the Zig project.

hello Example

This project has the following directory structure :

> tree /f /a . | findstr /v /b [A-Z]
|   build.bat
|   build.sh
|   build.zig
|   Makefile
\---src
    \---main
        \---zig
                hello.zig

Command zigbuild reads the project file build.zig to generate the Zig program zig-out\bin\hello.exe :

> zig build & zig-out\bin\hello.exe
Hello, world!

Command build.batrun generates and executes the Zig program target\hello.exe :

> build -verbose run
Compile 1 Zig source file to directory "target"
Execute Zig program "target\hello.exe"
Hello, world!

> make run
"C:/opt/zig-0.13.0/zig.exe" build-exe -femit-bin="target/hello.exe" src/main/zig/hello.zig
target/hello.exe
Hello, world!

closures Example

This project has the following directory structure :

> tree /a /f . | findstr /v /b [A-Z]
|   00download.txt
|   build.bat
|   build.sh
|   build.zig
|   Makefile
\---src
    \---main
        \---zig
                main.zig

Command build.batrun generates and executes the Zig program target\closures.exe :

> build -verbose run
Compile 1 Zig source file to directory "target"
Execute Zig program "target\closures.exe"
Successful Operation: b.val= 11

pointers Example

This project has the following directory structure :

> tree /a /f . | findstr /v /b [A-Z]
|   00download.txt
|   build.bat
|   build.sh
|   build.zig
|   Makefile
\---src
    \---main
        \---zig
                main.zig

Command build.batrun generates and executes the Zig program target\pointers.exe :

> build -verbose run
Compile 1 Zig source file to directory "target"
Execute Zig program "target\pointers.exe"
User 1 has power of 101

recursiveStructures Example

This project has the following directory structure :

> tree /a /f . | findstr /v /b [A-Z]
|   00download.txt
|   build.bat
|   build.sh
|   build.zig
|   Makefile
\---src
    \---main
        \---zig
                main.zig

Command build.batrun generates and executes the Zig program target\recursiveStructures.exe :

> build -verbose run
Compile 1 Zig source file to directory "target"
Execute Zig program "target\recursiveStructures.exe"
main.User{ .id = 1, .power = 9001, .manager = null }
main.User{ .id = 1, .power = 9001, .manager = main.User{ .id = 1, .power = 9001, .manager = null } }

timestamp Example

This project has the following directory structure :

> tree /a /f . | findstr /v /b [A-Z]
|   00download.txt
|   build.bat
|   build.sh
|   build.zig
|   Makefile
\---src
    \---main
        \---zig
                main.zig

Command build.batrun generates and executes the Zig program target\timestamp.exe :

> build -verbose run
Compile 1 Zig source file to directory "target"
Execute Zig program "target\timestamp.exe"
ts1=51
ts2=30
