Release 0.8.1 "Sale" - Multi-equation solver

c3d · c3d · commit e24ea66eef7f · 2024-10-14T14:40:48.000+02:00
Features
--------

* Multiple-equation solver (HP's MES), solves for variables one at a time
* The `|` operator (aka `where`) applies to library equations
* The `|` operator respects variables with units in expressions
* simulator: Add support for copy and paste (to/from simulator)
* Add support for cylindrical and spherical 2D and 3D vectors
* Positional graphic combination operations (e.g. `GraphicRatio`)
* Switch to Greek or Cyrillic keyboard maps based on character menu
* Add EDIT menu commands to transient alpha (e.g. ▶F3 is Word→)
* Index the  help file for performance (about 5x faster on DM42)
* Accept verbatim code and RPL code snippets in the help file
* Parse and show help topics taking all aliases into account
* Convert lists and equations to RPL programs with `→Program`

Bug fixes
---------

* Show tagged values for vectors and matrices
* Update the target global variable after running `root`
* Show all variables in the `SolvingMenu` (with a settings to control it)
* Unit-related commands accept tagged objects and expression-enclosed units
* Add angular units (e.g. radians) in angular equations
* Correct unit for `V` in `Cantilever Shear` (was `n` instead of `N`)
* `Purge` now correctly restores UI patterns settings
* Add missing font parameter to `→Grob` (HP calculator compatibility)
* Include equations and xlibs to list of symbolic objects
* Fix precision loss for `atan`, `acos` and `asin` for some values
* Add angles for `atan2` when using hardware-accelerated floating-point
* Remove spaces and separators in the names of library equations
* keyboard: Replace ASN with -&gt;NUM
* Preserve trailing decimal separator in `FIX` mode with `NoTrailingDecimal`
* Fix backspace and delete operation around number separators
* Fix the definition of `cosh` for complex values (was computing `sinh`)
* Accept uppercase and lowercase `.48s` when saving/restoring state
* Accept both `Ω` or `Ω` as spellings for Ohm (different Unicode)
* Only update the state file when disk operations are successful

Improvements
------------

* Add `arcsin`, `arccos` and `arctan` spellings
* solver: Reorganize solver code
* documentation: Udpate equation documentation with examples
* Save UI patterns as hexadecimal numbers (also in `Modes` command)
* Use only tabs in library.csv
* Keep cursor at end of buffer when moving through history with word right
* Clear selection when BSP is used with a non-empty selection
* Ensure `debug_printf` always refreshes the screen
* Switch to binary search for command parsing (~100x faster)
* Rename some statistical functions for consistency
* Fix the list of authors in the online help
* doc: Update performance data
