Tags and decorators

Squiggle now supports tags (Tag.* functions) and decorators (@decoratorName) that can be used to affect how the value is displayed. (#2572 and others).

Tags can be attached to any value, and decorators can be attached to any variable or function definition.

Decorators are proxied to Tag functions, e.g. @name("X var") x = 5 is the same as x = 5 -> Tag.name("X var").

Builtin tags: @name, @description, @format, @showAs, @hide.

• Tag percentage values with percentage format, so that they're rendered as percentages in viewer (#2759)

• Removed title attribute from Table.make(); you can use @name and @description tags instead (#2718)

Dates and Durations improvements (#2572).

Added date domains, f(x: [Date(1980), Date(2050)]), that's used in function plots for the x axis.

You can now type Date(2023) to represent Jan 1 2023.
