More Advanced Settings Template

[fodhelper]

Currently we have Settings/Headers template for each Transport of different Client Cores (Thanks to M03ED)

1. We can have multiple Settings for each transport in the Settings Template, and from GUI, user can select one for each Host or let it get selected randomly (I guess select random for all Hosts is enough)

If we don't need to specify a different Settings for each Host then this can do the job

import json, random

def random_from_array(data):
    if isinstance(data, list):
        return data[ random.randint(0, len(data)) - 1 ]
    else:
        return None

jsonFile = '''
{
  "grpcSettings": [
    {
      "data": "first"
    },
    {
      "data": "second"
    }
  ]
}
'''

jsonTemplate = json.loads(jsonFile)

# Print a random item
print( random_from_array(jsonTemplate["grpcSettings"]) )

# Check if Array is valid
if random_from_array(jsonTemplate):
    print("valid")
else:
    print("in-valid")

# Check if Array is valid
if random_from_array(jsonTemplate["grpcSettings"]):
    print("valid")
else:
    print("in-valid")

2. We can add multiple v2rayNG sockopt template and let user select one for each Host (Here the ability to select random must not exist i guess)
   https://xtls.github.io/config/transport.html#sockoptobject
   sing-box have dial settings instead of sockopt :
   https://sing-box.sagernet.org/configuration/shared/dial/
   and Clash.Meta have common proxy settings :
   https://wiki.metacubex.one/en/config/proxies/

Here is a function but it needs GUI changes that i can't do them myself

import json, random

def get_item(data, by_name=None):
  if by_name != None:
    if by_name in data:
      return data[by_name]
    else:
      return None
  else:
    keys = list(data.keys())
    random_key = random.choice(keys)
    return data[random_key]

jsonFile = '''
{
  "tree": {
    "0": {
      "data": "aaa0",
      "data": "aaa1",
      "data": "aaa2",
      "data": "aaa3"
    },
    "1": {
      "data": "bbb12"
    },
    "2": {
      "data": "ccc34"
    },
    "3": {
      "data": "ddd56"
    }
  }
}
'''

jsonTemplate = json.loads(jsonFile)

# Print a random item
print( get_item(jsonTemplate["tree"]) )

# Print a random item
print( get_item(jsonTemplate["tree"]["0"]) )

# Print item with name "0"
print( get_item(jsonTemplate["tree"], by_name="1") )

# Check if item with name "2" exist or not
if get_item(jsonTemplate["tree"], by_name="2"):
    print("exist")
else:
    print("not exist")

# Check if item with name "5" exist or not
if get_item(jsonTemplate["tree"], by_name="5"):
    print("exist")
else:
    print("not exist")

This and #1190 will be so good for pro users
