Parser Support

Parser Cli2Gui Gooey Quick
Argparse :heavy_check_mark: :heavy_check_mark: :x:
Optparse :heavy_check_mark: :x: :x:
DocOpt :heavy_check_mark: :x: :x:
Click :heavy_check_mark: * :x: :heavy_check_mark:
GetOpt :heavy_check_mark: :x: :x:
Dephell Argparse :heavy_check_mark: :x: :x:
* Partial support (use Click2Gui)

This works for simpler programs but sadly falls flat for more complex programs

GUI Feature Support

Basic GUI Cli2Gui Gooey Quick

Element Size :heavy_check_mark: :x: :x:
Custom Images :heavy_check_mark: :heavy_check_mark: :x:

Cli2Gui is pretty lacking in these features and will probably remain that way to ease maintainability - the primary aim is to support multiple argparse libraries over fancy widgets

Advanced GUI Cli2Gui Gooey Quick

Feature Description Status
Python Fire Under consideration


@Cli2Gui(run_function, auto_enable=False, parser="argparse", gui="pysimplegui",
		theme="", darkTheme="", sizes="", image="", program_name="",
		program_description="", max_args_shown=5, **kwargs)

Using the decorator in your project

run_function (optional)

The name of the function to call eg. main(args). Defaults to None. If not specified, program continues as normal (can only run once)

def main(args):

def cli():
	parser = argparse.ArgumentParser(description="this is an example parser")
	parser.add_argument("arg", type=str,
		help="positional arg")
	args = parser.parse_args()

auto_enable (optional)

Enable the GUI by default. If enabled by default requires --disable-cli2gui, otherwise requires --cli2gui


parser (optional)

Override the parser to use, defaults to argparse. Current options are: "argparse", "getopt", "optparse", "docopt", "dephell_argparse"


gui (optional)

Override the gui to use. Current options are: "pysimplegui", "pysimpleguiqt","pysimpleguiweb". Defaults to "pysimplegui".

pysimplegui is the recommended option


theme (optional)

Set a base24 theme. Can also pass a base24 scheme file. eg. one-light.yaml

@Cli2Gui(theme=["#e7e7e9", "#dfdfe1", "#cacace", "#a0a1a7", "#696c77",
		"#383a42", "#202227", "#090a0b", "#ca1243", "#c18401", "#febb2a",
		"#50a14f", "#0184bc", "#4078f2", "#a626a4", "#986801", "#f0f0f1",
		"#fafafa", "#ec2258", "#f4a701", "#6db76c", "#01a7ef", "#709af5",

darkTheme (optional)

Set a base24 dark theme variant. Can also pass a base24 scheme file. eg. one-dark.yaml

@Cli2Gui(darkTheme=["#282c34", "#3f4451", "#4f5666", "#545862", "#9196a1",
		"#abb2bf", "#e6e6e6", "#ffffff", "#e06c75", "#d19a66", "#e5c07b",
		"#98c379", "#56b6c2", "#61afef", "#c678dd", "#be5046", "#21252b",
		"#181a1f", "#ff7b86", "#efb074", "#b1e18b", "#63d4e0", "#67cdff",

sizes (optional)

Set the UI sizes such as the button size

		"title_size": 28,
		"label_size": (30, None),
		"input_size": (30, 1),
		"button":(10, 1),
		"padding":(5, 10),
		"helpText_size": 14,
		"text_size": 11})

image (optional)

Set the program icon. File extensions can be any that PIL supports


program_name (optional)

Override the program name

@Cli2Gui(program_name="custom name")

program_description (optional)

Override the program description

@Cli2Gui(program_description="this is a custom description")

max_args_shown (optional)

Maximum number of args shown before using a scrollbar


menu (optional)

Add a menu to the program. Defaults to None. eg.

THIS_DIR = str(Path(__file__).resolve().parent)
menu={"File": THIS_DIR + "/"}

Works significantly better with pysimplegui than pysimpleguiqt

@Cli2Gui(menu={"File": THIS_DIR + "/", "Another File": THIS_DIR + "/", })


def Click2Gui(run_function, gui="pysimplegui", theme="", darkTheme="",
		sizes="", image="", program_name="", program_description="",
		max_args_shown=5, menu="", **kwargs):

Very similar to the decorator but with the following differences...

run_function (required)

Specify the click function to use. (attempts were made to offer full program support however this behaved very poorly)

parser (not applicable)

As this is exclusively for click, this option is not present
