lxRegMasterDiffName

lxRegMasterDiffName(
S_function
)
=> t / nil

Description

Registers a SKILL function that can return a name for the master difference reported by the Check Against Source command.

Argument

S_function

Name of the SKILL function to be registered. The SKILL function must take the following two arguments and return a string. master: Database cellview ID of the current layout instance master. expected: String value representing the expected master in the format lib/cell/{view1 view2}. The master may have one or multiple views defined in CPH.

Value Returned

t	The SKILL function was registered.
nil	The SKILL function registration failed.

Example

lxRegMasterDiffName('testMasterDiffName)

Where the SKILL function testMasterDiffName is defined as:

procedure(testMasterDiffName1(master expected)

    let((_mbbox _cv _tok _lib _cell _view _views (_name "")

         cH nH cW nW _nbbox)

        _tok = parseString(expected "/")

        _lib = car(_tok)

        _cell = cadr(_tok)

        _views = caddr(_tok)

        _view = substring(_views 2 (strlen(_views) - 2))

        _tok = parseString(_view " ")

        _view = car(_tok)

        _cv = dbOpenCellView(_lib _cell _view)

        when(_cv

            _mbbox = master~>bBox

            cH = testBoxDimY(_mbbox)

            cW = testBoxDimX(_mbbox)

            _nbbox = _cv~>bBox

            nH = testBoxDimY(_nbbox)

            nW = testBoxDimX(_nbbox)

            cond(

                (nH > cH && nW > cW 

                   _name = "Taller and wider"

                )

                (nH < cH && nW < cW

                   _name = "Shorter and thiner"

                )

                (testEqualBasic(nH cH) && nW > cW 

                   _name = "Wider"

                )

                (testEqualBasic(nH cH) && nW < cW 

                   _name = "Thinner"

                )

                (nH > cH && testEqualBasic(cW nW)

                   _name = "Taller"

                )

                (nH < cH && testEqualBasic(cW nW)

                   _name = "Shorter"

                )

            )

            dbClose(_cv)

        )

        _name

    )
