    pip install asfamc-parser

features:

• ASF parser
• AMC parser
• Simple, Clean data structure.

Imports

    from asfamcparser import ParseASF, ParseAMC

Data Structure

Joint

Immutable class where every property is optional.

    JOINT
        - name : str
        - dof  : NamedTuple e.g (rx=(-inf,inf), ry=(-inf,inf), rz=(-inf,inf))
        - direction : Tuple e.g (0.0, 1.2, 2.2)
        - length : float
        - axis : NamedTuple e.g (X=0.0, Y=0.0, Z=0.0)
        - order : Tuple e.g ("X", "Y", "Z")

NamedTuple values can be accessed either through their index or their names as follows:

    axis.X

ASF

Immutable class.

    ASF
        - name : str
        - units : NamedTuple e.g ("mass"="kg", "length"="mm", "angle"="Deg")
        - doc : str
        - joints : Tuple[Joint, ...]
        - hierarchy : dict where each key corresponds to a a joint that has children.

Individual joints can be retrieved using the dict key method as follows:

    LElbowJoint = ASF["LeftElbow"]

Also, all joints can be accessed through for iterations:

    for joint in ASF:
        print( joint.name )

AMC

Immutable class

    AMC
        - count:int (number of frames)
        - frames: Tuple[dict,...] 

Individual frames can be retrieved using the dict key method as follows:

    frameTen = AMC[10]

Individual frames and specific joint data can be retrieved using the dict key method as follows:

    frameTenHead = AMC[10]["Head"]

Also, all frames can be accessed through for iterations:

    for frame in AMC:
        print( frame.count )

Examples:

ParseASF

The full path to the .asf file is required to parse.

    parsedAsf = ParseASF("./recordings/test.asf")
    asf = parsedASF.asf

The retrieve asf file can be navigated using its properties described in the data structudre section.

ParseAMC

The full path to the .amc file is required to parse.

    parsedAmc = ParseAmc("./recordings/test.amc")
    amc = parsedAMC.amc

The retrieved amc file can be navigated using its properties described in the data structure section.
