Release 0.8.10 "Fire Dove" - Input and Prompt, Android preparation

[c3d]

The focus of this release is support for user input in programs, with the addition of the Input and Prompt commands. Internally, a lot of groundwork was performed towards Android builds.

New features

• Add Prompt command, which programs can use to let users manipulate the stack or do other operations before resuming execution.

• In order to facilitate the use of Prompt, added the Run command, which resumes execution of halted programs and otherwise evaluates the first item on the stack. The key at the left of the + key, which is labeled R/S on the DM-42 calculators, is now bound to the Run command instead of Evaluate. Therefore, after a Prompt, you can resume execution with a single key.

• Add Input command, which programs can use to let users enter data. The DB48x version makes it easier to enter and validate numerical data or other non-text objects, with input validators for numbers, integer values, arithmetic objects or expressions. It is also possible to use custom code to validate user input.

• Additional Compile variants were created to help with this user input validation, checking if the input is a number, an integer, a positive integer, a real number, a single object, a single algebraic object or an expression.

Bug fixes

• Fixed problem with the computation of the length of the integer value being parsed if it was parsed from a text value at the end of the temporaries.

• Emit an error from Step and variants if no program is being debugged. The effect was that the next program being run would halt after the first step.

• Avoid persisting beep in the simulator when two beeps were emitted rapidly in successioon.

• Reload the user-selected keymap file after loading the state file.

Improvements

• Change capitalization of DTag as a shortcut for DeleteTag.

• Various code improvements making it easier to compile for Android. A side effect is that the simulator can now safely be started from any current directory.

• Improve rescaling of the window in the simulator to keep the keyboard and screen larger and easier to read.

• Improve the detection of the default simulator size for Hi-DPI screens.

• Add documentation about matrix multiplication performance

• Make the default memory size more consistent with the simulated device.
