GoFrame v2 development skill. Use only when the target Go project uses or is explicitly adopting GoFrame v2: the nearest go.mod requires github.com/gogf/gf/v2, existing Go files import github.com/gogf/gf/v2 or any github.com/gogf/gf/v2/... component package, or the user asks to scaffold, migrate, or build with GoFrame. Trigger for GoFrame-backed Go work such as APIs/controllers/services, middleware, routing/config, ORM/DAO/DO/entity/database operations, gf CLI/codegen, HTTP/gRPC services, and microservice conventions. Do not trigger for generic Go projects without GoFrame evidence, frontend-only work, shell scripts, or unrelated infrastructure tasks.

执行Shell命令

package main

import (
    "fmt"

    "github.com/gogf/gf/v2/os/gctx"
    "github.com/gogf/gf/v2/os/gproc"
)

func main() {
    r, err := gproc.ShellExec(gctx.New(), `sleep 3; echo "hello gf!";`)
    fmt.Println("result:", r)
    fmt.Println(err)
}

执行后,可以看到程序等待了3秒之后,输出结果为:

result: hello gf!

<nil>

主进程与子进程

由 gproc.Manager 对象创建的进程都默认带子进程标识,在子进程程序中可以通过 gproc.IsChild() 方法来判断自身是否为子进程。

package main

import (
    "os"
    "time"

    "github.com/gogf/gf/v2/frame/g"
    "github.com/gogf/gf/v2/os/gctx"
    "github.com/gogf/gf/v2/os/gproc"
)

func main() {
    var ctx = gctx.New()
    if gproc.IsChild() {
        g.Log().Printf(ctx, "%d: Hi, I am child, waiting 3 seconds to die", gproc.Pid())
        time.Sleep(time.Second)
        g.Log().Printf(ctx, "%d: 1", gproc.Pid())
        time.Sleep(time.Second)
        g.Log().Printf(ctx, "%d: 2", gproc.Pid())
        time.Sleep(time.Second)
        g.Log().Printf(ctx, "%d: 3", gproc.Pid())
    } else {
        m := gproc.NewManager()
        p := m.NewProcess(os.Args[0], os.Args, os.Environ())
        p.Start(ctx)
        p.Wait()
        g.Log().Printf(ctx, "%d: child died", gproc.Pid())
    }
}

执行后,终端打印结果如下:

2018-05-18 14:35:41.360 28285: Hi, I am child, waiting 3 seconds to die
2018-05-18 14:35:42.361 28285: 1
2018-05-18 14:35:43.361 28285: 2
2018-05-18 14:35:44.361 28285: 3
2018-05-18 14:35:44.362 28278: child died

多进程管理

gproc 除了能够创建子进程,管理子进程之外,也能管理非自身创建的其他进程。 gproc 可以同时管理多个进程,这里以单个进程为例来演示对进程的管理功能。

  1. 我们使用 gedit 软件(Linux下常用的文本编辑器)随意打开一个文件,在进程当中我们看到该gedit的进程ID为 28536
    $ ps aux | grep gedit
    john  28536  3.6  0.6 946208 56412 ?  Sl  14:39  0:00 gedit /home/john/Documents/text
  1. 我们的程序如下:
package main

import (
       "fmt"

       "github.com/gogf/gf/v2/os/gproc"
)

func main() {
       pid := 28536
       m := gproc.NewManager()
       m.AddProcess(pid)
       m.KillAll()
       m.WaitAll()
       fmt.Printf("%d was killed\n", pid)
}

执行后, gedit 被关闭,终端输出信息为:

28536 was killed

    The skill provides a comprehensive development guide and code examples for the GoFrame v2 framework. While highly informative for Go developers, it contains several examples with hardcoded placeholder secrets, tokens, and specific local file paths to sensitive configuration files (like Kubernetes credentials). These elements are provided for demonstration purposes but represent insecure practices if used in production without modification.

README badge

README badge for gogf/skills

Provides instruction and conventions for developing with GoFrame v2, a modular Go framework for building HTTP and gRPC services, microservices, and database operations using its ORM, CLI tooling, and project scaffolding. Use this skill when the target project has GoFrame v2 as a dependency or when the user requests scaffolding, migrations, or service development with GoFrame conventions.

Generated from the current SKILL.md.

When should I use this skill?
Use this skill only when your Go project uses GoFrame v2, indicated by github.com/gogf/gf/v2 in go.mod or imports. Do not use for generic Go projects, frontend work, or infrastructure tasks unrelated to GoFrame.
Should I manually set created_at and updated_at fields?
No. GoFrame automatically writes created_at on insert and updated_at on insert/update/save. Manually setting these fields is redundant and violates project conventions.
What should I use for database operations instead of g.Map?
Always use DO objects from internal/model/do/. DO struct fields are interface{}, unset fields remain nil and are automatically ignored by the ORM.
How does soft delete work in GoFrame?
Call Delete() on the DAO; GoFrame automatically converts it to UPDATE SET deleted_at = NOW(). Queries automatically filter out soft-deleted rows without requiring manual WhereNull conditions.
Where should I implement business logic?
Implement business logic directly in the service/ directory. Do not use the logic/ directory unless explicitly requested.
