logic duplicated

air/runner/config.go

Lines 324 to 331 in ad8fbb7

	c.Build.ExcludeDir = ed
	if len(c.Build.FullBin) > 0 {
	c.Build.Bin = c.Build.FullBin
	return err
	}
	// Fix windows CMD processor
	// CMD will not recognize relative path like ./tmp/server
	c.Build.Bin, err = filepath.Abs(c.Build.Bin)

can we just extract

air/runner/config.go

Lines 324 to 331 in ad8fbb7

	c.Build.ExcludeDir = ed
	if len(c.Build.FullBin) > 0 {
	c.Build.Bin = c.Build.FullBin
	return err
	}
	// Fix windows CMD processor
	// CMD will not recognize relative path like ./tmp/server
	c.Build.Bin, err = filepath.Abs(c.Build.Bin)

as a function add put after

air/main.go

Line 97 in ad8fbb7

cfg.WithArgs(cmdArgs)

[sdfwds4]

func (c *Config) PostProcess() error {
	if len(c.Build.FullBin) > 0 {
		c.Build.Bin = c.Build.FullBin
		return nil
	}
	// Fix windows CMD processor
	// CMD will not recognize relative path like ./tmp/server
	var err error
	c.Build.Bin, err = filepath.Abs(c.Build.Bin)
	return err
}

cfg.WithArgs(cmdArgs) 
cfg.PostProcess()          // 给cfg增加额外的对外接口，增加使用复杂度

假如我像上面那样修改，PostProcess的功能仅是对c.Build.FullBin和filepath.Abs的简单封装，会给cfg增加额外的对外接口，增加使用复杂度，就不符合KISS原则了

sorry i need to write in English, cause there are contributors all around the world. and i made WithArgs private, and hide logic in preprocess function. i think this way should be better.
