|  | ||||
|  | ||||
|  - Build wasm & push changes | ||||
|  - Update AUR package | ||||
|  | ||||
| ## Pre-release | ||||
|  - Fix linelocation (consistent, what does an operator's linelocation mean?) | ||||
|  - Tuple operations | ||||
|  - we don't need vectors as arguments to operators | ||||
|  - Assignment tests | ||||
|  | ||||
| ## Parser | ||||
|  - Better error when `sin = 2` | ||||
|  - Should functions be operators? | ||||
|  - Binary, hex, octal numbers | ||||
|  | ||||
|  | ||||
| ## General | ||||
|  - Better tests (assignment, many expressions in one context) | ||||
|  - Optional config file | ||||
|  - Optional history file | ||||
|  - daisyrc file | ||||
|  - Compile to WASM, publish a webapp | ||||
|  - Options: | ||||
|    - disable replacement | ||||
|    - disable special characters | ||||
|    - 1/ as -1 power toggle | ||||
|    - powers as superscripts toggle | ||||
|  - evaluate straight from command line | ||||
|  - Auto-push to crates.io | ||||
|  - Package for debian | ||||
|  | ||||
|  | ||||
|  | ||||
| ## Internals | ||||
|  - Package for debian, nix | ||||
|  - Non-recursive treeify | ||||
|  - Faster factorial function. Maybe use gamma instead? | ||||
|  - Arbitrary precision float (rug doesn't offer arbitrary exponents) | ||||
|  - Remove rug dependency (too big, incompatible) | ||||
|  - Arbitrary precision floats | ||||
|  | ||||
| ## Math Features | ||||
|  - Dice | ||||
|  - Mean, Median, Min | ||||
|  - Arbitrary base logarithm | ||||
|  - Derivatives | ||||
|  - CAS features (trig, roots and powers) | ||||
|  - Complex numbers | ||||
|  - acot/acoth functions | ||||
|  - Sums and products with functional arguments | ||||
|  - Add functions: gcd, inverse mod, dice | ||||
|  | ||||
| ## Prompt | ||||
|  - Fix terminal color detection | ||||
|  - Live syntax/output (like firefox js terminal) | ||||
|  - Syntax highlight input and output | ||||
|  - fish-style tab completion | ||||
|  - Numbered expressions, history recall | ||||
|  - Color configuration | ||||
|  - Syntax highlighting | ||||
|  - Numbered history recall | ||||
|  - Enable/disable unit sets (defaults?) | ||||
|  - Consistent unit ordering | ||||
|  - Better linelocation | ||||
|    - we shouldn't need to re-print user input on evaluation errors, red arrows should adjust themselves to the prettyprinted string | ||||
|  - Backend-independent colorful printing | ||||
|    - Better colors in error texts | ||||
|  - Better substitution. Consistent: when ascii, when unicode? | ||||
|  - Command to list substitutions | ||||
|  | ||||
| ## Units | ||||
|  - long prefixes (megatonne, etc) | ||||
