FMSLogo Code

Add some tests to make sure that comparisons on DLL names are case-insensitive.

Implemented Feature Request #1947329; FMSLogo now supports loading more than one DLL with DLLLOAD.

Implement request #2084889; "comment", "semicolon", and ";" are now in the index.

Implement request #1955758; turtles may optionally have their own pen state.

Implement request #1955758; turtles may optionally have their own pen state.

The involved adding a PENSTATE structure to the Turtle structure and a boolean to keep track of if the PENSTATE is used. All access to the current pen state is done through a new accessor called GetPenStateForSelectedTurtle(), which will use either the global pen state or the g_SelectedTurtle.PenState, depending on if the selected turtle has its own pen state.

Any change to the turtle now also changes the currently used brushes and updates the status window, as appropriate.

Refactor all of the global pen state variables into a single struct. This is part of a phased implementation of feature request #1955758; implementing an optional per-turtle pen state.

Add the Set Pen Color, Set Screen Color, and Set Flood Color dialog boxes, following the model of Set Pen Size.

Use wxID_OK, instead of inventing my own ID for the OK button. I'm not sure what effect this has on FMSLogo, but it seems like the right thing to do.

Integrate updates to the Greek translation from Theodoros Chatzigiannakis.

Update test log based on 6.21.0 full test pass.
