Accessibility

ConsoleMVC has two modes that users can turn on without a new build of your application.

Screen readers

dotnet run -- --ConsoleMVC:ScreenReader=true
# or
export ConsoleMVC__ScreenReader=true

Or always, in Program.cs:

builder.ScreenReader = true;

Every screen is then written as plain lines of text that a screen reader reads well:

Element	Read as
<box title="Account">	Account, then the box's content
<table>	one line per row: Name: Ada, Age: 36
<columns>	each column, one after another
<separator />	nothing
<progress>	Import: 75%
<spinner>	its label, then Connected: done
<bar-chart>	Mon: 12 for each bar
<sparkline>	Load: 30 values from 10 to 89, latest 14
<shortcuts />	Shortcuts: Esc Back, Ctrl+X Quit
<breadcrumbs />	You are here: Home, Orders
<markdown>	without rules; quotes start with Quote:

Also:

• No colours and no cursor movement. <select>, <radio>, <checkbox>, <number> and <date> list numbered choices and read a typed answer instead of the arrow keys.
• Screens are not erased: a blank line separates them, so what was read stays in the reader's history.
• Live regions draw their final state once, <scroll> draws everything, and FullScreen is ignored.

Your own elements are drawn as they are. To describe one in words, wrap the renderer yourself, or check Renderer is ScreenReaderRenderer in a view and draw something simpler.

High contrast

dotnet run -- --ConsoleMVC:HighContrast=true

builder.HighContrast = true;            // or: builder.Theme = Theme.CreateHighContrast();

The built-in classes (title, muted, success, warning, danger, info, panel) use bold, bright colours with no dim text, and panels get heavy white borders. High contrast replaces builder.Theme, so add your own classes to Theme.CreateHighContrast() if you need them in both.

NO_COLOR (https://no-color.org) is respected as before: with it set, nothing is coloured.
