The difference between SysArgv and AppArguments() from stdlibcore.ring

[Mahmoud Fayed]

Hello

When creating command line utilities that accept arguments from the user through the terminal, we have two options

(1) Using: SysArgv (global variable)

(2) Using AppArguments() function from stdlibcore.ring

It's always recommended to use AppArguments() to avoid the executable name and script file name which are stored in SysArgv

Example:

Program Name: apparg.ring

load "stdlibcore.ring"

? sysargv
? "******"
? apparguments()
? "******"

Test (1): ring apparg.ring para1 para2

Output:

ring
apparg.ring
para1
para2

******
para1
para2

******

Using appArguments() we just get (para1) and (para2), i.e. what we care about

Test(2):

ring2exe apparg.ring -static

apparg para1 para2

Output:

apparg
para1
para2

******
para1
para2

******

Again, using appArguments() we just get (para1) and (para2), i.e. what we care about
