How to use appargs

[FrenchGithubUser]

I have tried to use the appargs variable in the wails.json config file like this :

"appargs": "mode=dev"

I also tried starting wails with args like this : wails dev -appargs "mode=dev".

Then, the args are read in the main.go file (and stored in a variable) :

flag.Parse()
variables.ARGS = flag.Args()

But the variable is always empty. What am I doing wrong ?

Can you show a little more code, including when you read os.Args and pass them into flag.Parse()?

The issue came from the fact that I was trying to read the flags in the main function. For some reason, the code was not executed there. So I now read them in the NewApp() function. Is it considered as the way to do it ?

I am confused with args

Can someone help please

I parse flags ar main.go using

lclConfigFlag := flag.String("config", "", "Configuration file.")
	flag.Parse()
	fmt.Println("Config flag value:", *lclConfigFlag)

and execute

wails dev  -appargs "-config SOME_FILE"
wails dev --appargs "-config SOME_FILE"
wails dev -appargs "config SOME_FILE"
wails dev -appargs "--config SOME_FILE"
wails dev -appargs "config SOME_FILE"

If I build I can pass the flag successfully
