notecalc3

[0.3.0] - 2020-12-21

Breaking Changes

• Spaces are not allowed in hex numbers anymore but undorscores are. It caused problems since 0xAA B could not be unambiguously parsed (e.g. it can be 0xAAB or 0xAA B, where 'B' is a unit for 'bytes', so make it explicit by writing 0xAA_B).

Features

• Dark Theme
• Render command optimizations, reducing render command count by around 40% (gutters, line number- and result backround are now rendered only once as a big rectangle and not line by line).
• Active references (variables and line refs in the cursor's row) are now just underlined and the referenced lines are not highlighted fully only their left and right gutter. (Look at the image below)
• Results where a denominator is a unit (e.g. 5 / year) are now rendered in a more user-friendly way (e.g. instead of 5 year^-1 it is 5 / year)
• Automatic closing parenthesis/braces insertion when the opening one is typed
• Automatic closing parenthesis/braces deletion when the opening one is deleted
• Automatic parenthesis/braces wrapping around selected text if opening one is typed while a text is selected
• Matching parenthesis are highlighted if the cursor is inside them
• The note can be saved with ctrl-s (Though it is still saved automatically when there is no user interaction)
• It is possible to apply units directly on Line References or Variables, e.g.

  var = 12
  var km
  

  The result of the second line will be 12 km
• Parsing improvement: Now the parser are smarter in deciding what is an operator (e.g. 'in' in 12 m in cm), a unit (12 in which is 12 inch), or a simple string (I downloaded 12 GB in 3 seconds). Now it is even possible to evaluate this string 12 in in in, which is equivalent of 12 inch in inch
• Percentage calculations
• Max row count was increased from 128 to 256
• e (Euler's Number) was added, currently as a function (e())
• Invalid argument types for functions are highlighted as errors (See image below)
• new functions:
  
  • abs(num)
  • ln(num)
  • lg(num)
  • log(num, num)
  • sin(angle) -> num
  • cos(angle) -> num
  • tan(angle) -> num
  • asin(num) -> angle
  • acos(num) -> angle
  • atan(num) -> angle

Changed

• When opening a not empty note, the result panel now tries to be as close to the editor as possible to have a better overview about calculations and their results.
• GitHub and website links were added to the NoteCalc page
• Strings at the frontend are now rendered char by char. It is necessary to be able to place the cursor at the right place, since the text rendering does not guarantee that a single char takes exactly 'char-width' pixels.
• Overlay canvas

[0.2.0] - 2020-12-03

Breaking Changes

• -- does not set the sum variable to zero, but every header does

Features

• Mobile support for index.html and notecalc itself
  • typing using the native virtual keyboard
  • scrolling
• High DPI rendering
• Headers (# Header) and region-specific alignments (different regions under different headers can have different alignments, making the result output more ergonomic).
• Comments are supported (e.g. 12 + 3 // it should be 15)
• Hovering effect for the scrollbar
• Cursor changes to 'w-resize' when above the right gutter to highlight that it is draggable
• Line count limitation was increased from 64 to 128
• Default precision limitation both from the result panel and from the inserted line references was removed. It caused problems since very small numbers could appear as "0" due to roundings. It might be inconvenient in some situations but will be fixed when rounding specifiers will be implemented. Though, NoteCalc tries its best to render a compact form (e.g. removes repetends etc)

Changed

• Tutorial is updated with the new features and now stored in GIT
• Leangains demo is updated

Fixes

• In case a line reference was rendered outside of the editor area, '...' did not appear at the edge of the editor
• Firefox tracking protection issue for webfont.js
• Variable-reference pulsing pulsed continously when the right gutter was dragged
• The result panel is automatically resizing now with respect to browser width, required space for results and required space for the editor panel's content
• The binary and hex representation gives Err for quantities and percentages
• Lines that are too long and are covered by the result panel renders dots ('...') on the panel.
• The dots for matrices are now rendered for all the matrix's rows
• '…' was not rendered correctly for Matrices
• Ctrl-t is not absorbed by the frontend anymore
• Undoing (Ctrl-z) a selection removal with DEL button was buggy and only the first line of the selection was reparsed
• Pulses (which highlights the usage places of variable/lineref under the cursor) appeared too slowly when navigating with cursor or mouse, making it more difficult for the user to notice it immediately.
• Space is automatically inserted in front of a just-inserted line reference
• Right gutter alignment was a render pass late to the input which caused it
• Cursor was not visible at the right edge of the editor
• Global static RESULT_BUFFER is now part of the lib and not of the frontend (introduces some unsafe code but less trouble with the borrow checker)
• Fixed error when variable name is empty

Removed

• local.html was removed, you can access now the debug functionality and local wasm file via host/notecalc?debug
