How to pass application parameters to cq-editor

[winksaville]

I tried this:

if len(sys.argv) != 6:
    print("Usage: rerf-cubes <filename> <format> <cube_count> <cube_size> <tube_size>")
    print("       <filename>:   Name of the output file (without extension)")
    print("       <format>:     Format to export the model ('stl' or 'step')")
    print("       <cube_count>: Number of cubes to create (1 or 4)")
    print("                     cube number is engraved on the +Y face")
    print("       <cube_size>:  Size of the cube engraved on the +X face")
    print("       <tube_size>:  Tube size and engraved on the -X face")
    print("Example: ./rerf-cube my_cube stl 1 2.397 0.595")
else:
    file_name = sys.argv[1]
    file_format = sys.argv[2]
    cube_count = int(sys.argv[3])
    cube_size = float(sys.argv[4])
    tube_size = float(sys.argv[5])
    layer_height = 0.050
    support_len = 5.0
    base_layers = 5

build_object = doit(file_name, file_format, cube_count, cube_size, tube_size)

if __name__ == "__main__":
    # so stuff
    logging.info(f"__main__ logging.info: __name__: {__name__}")
elif __name__ == "__cq_main__":
    logging.info(f"__cq_main__ logging.info: __name__: {__name__}")
    show_object(build_object, name=file_name)
else:
    logging.info(f"Unreconized __name__: {__name__}")

But I get the error unrecognized arguments

$ cq-editor rerf-cubes.py boxes-at-corners stl 4 2.397 0.595
usage: cq-editor [-h] [filename]
cq-editor: error: unrecognized arguments: boxes-at-corners stl 4 2.397 0.595

So ATM I'm doing this which isn't very satisfactory I'm guessing/hoping there is something better:

if __name__ == "__main__":
    logging.info(f"__main__ logging.info: __name__: {__name__}")
    print(f"__main__ logging.info: __name__: {__name__}")

    if len(sys.argv) != 6:
        print("Usage: rerf-cubes <filename> <format> <cube_count> <cube_size> <tube_size>")
        print("       <filename>:   Name of the output file (without extension)")
        print("       <format>:     Format to export the model ('stl' or 'step')")
        print("       <cube_count>: Number of cubes to create (1 or 4)")
        print("                     cube number is engraved on the +Y face")
        print("       <cube_size>:  Size of the cube engraved on the +X face")
        print("       <tube_size>:  Tube size and engraved on the -X face")
        print("Example: ./rerf-cube my_cube stl 1 2.397 0.595")
    else:
        file_name = sys.argv[1]
        file_format = sys.argv[2]
        cube_count = int(sys.argv[3])
        cube_size = float(sys.argv[4])
        tube_size = float(sys.argv[5])
        layer_height = 0.050
        support_len = 5.0
        base_layers = 5

        build_object = doit(file_name, file_format, cube_count, cube_size, tube_size)
elif __name__ == "__cq_main__":
    logging.info(f"__cq_main__ logging.info: __name__: {__name__}")

    #file_name = "boxes-at-corners"
    file_name = "supported_cube"
    file_format = "stl"
    cube_count = 1
    layer_height = 0.030
    base_layers = 5
    cube_size = 2.397
    tube_size = 0.595
    support_len = 5.0

    build_object = doit(file_name, file_format, cube_count, cube_size, tube_size)

    show_object(build_object, name=file_name)
else:
    logging.info(f"Unreconized __name__: {__name__}")

@winksaville What is your use case? CQ-editor was not designed for this use to my knowledge. It is designed for user -manipulation of parameters in the Editor/UI.

The two other ways that I can think of to do what you want would be to use environment variables, and to inject the parameters into globals. Neither option seems very efficient.

Have you looked at cadquery.vis.show, which is built-in to CadQuery?

[winksaville]

@jmwright my use case is quite simple. I've created a command line program, https://github.com/winksaville/rerf-cubes-cq,
and I'm using cq-editor to quickly visualize changes and see debug output and such.
I've setup cq-editor to use an external editor and it works quite well. The only thing missing is getting parameters.

If allowing parameters is feasible, I'd like to have a pane in the cq-editor where I could change parameters, that would make it quite nice to have a crude gui for my command line program with basically no effort!.

For actually passing parameters I'd suggest separating cq-editor parameters from the "app" using the
-- technique something like:

cq-editor rerf-cubes.py -- boxes-at-corners stl 4 2.397 0.595

Thoughts?

I'd like to have a pane in the cq-editor where I could change parameters

There is already a parameters pane that is supposed to fulfill this function on the right side of the UI, but I never use it. If the parameters are not populating in that for you, maybe we should start by investigating why that is not working.

[winksaville]

I now see that pane, it's between the Objects and Variables. But since there extra parameters are accepted there is nothing to display, here is an example where I use it without cq-editor:

(cqed) (base) wink@3900x 25-04-14T00:24:38.847Z:~/data/prgs/3dprinting/rerf-cubes-cq (main)
$ ./rerf-cubes.py boxes-at-corners stl 4
(cqed) (base) wink@3900x 25-04-14T00:25:16.408Z:~/data/prgs/3dprinting/rerf-cubes-cq (main)

And here is what I'd like to do but I get the error unrecognized arguments:

(cqed) (base) wink@3900x 25-04-14T00:26:19.758Z:~/data/prgs/3dprinting/rerf-cubes-cq (main)
$ cq-editor ./rerf-cubes.py boxes-at-corners stl 4
usage: cq-editor [-h] [filename]
cq-editor: error: unrecognized arguments: boxes-at-corners stl 4
(cqed) (base) wink@3900x 25-04-14T00:26:28.131Z:~/data/prgs/3dprinting/rerf-cubes-cq (main)

Here is when I execute it without the parameters and just use the defaults I coded:

(cqed) (base) wink@3900x 25-04-14T00:26:28.131Z:~/data/prgs/3dprinting/rerf-cubes-cq (main)
$ cq-editor ./rerf-cubes.py

And here is the result when I "render" it, looks great but as you can see the Parameter | Value window is rightfully empty:
