* Replace Region.Contains LINQ lambdas with foreach loop Removes the lambda func allocations caused by captured outer variables. * Replace LineCanvas.Has LINQ lambda with foreach loop * Fix LineCanvas.GetMap intersects array nullability It should be enough to add null-forgiving operator somewhere in the LINQ query to make the final result non-null. No need to shove the nullability further down the line to complicate things. :) * Replace LineCanvas.All LINQ lambda with foreach loop * Replace Region.Intersect LINQ lambdas and list allocation with foreach loop and rented array * Use stackalloc buffer in Region.Intersect when max 8 rectangles * Fix LineCanvas.GetCellMap intersects array nullability * Remove leftover LineCanvas.GetRuneForIntersects null-conditional operators * Remove leftover IntersectionRuneResolver.GetRuneForIntersects null-conditional operators * PosAlign.CalculateMinDimension: calculate sum during loop No need to first put the dimensions in a list and then sum the list when you can just add to sum while looping through dimensions. * PosAlign.CalculateMinDimension: Remove intermediate list and related filter func allocation * TextFormatter.GetRuneWidth: Remove intermediate list and related sum func allocation * ReadOnlySpan refactor preparation for GetCellMap rewrite * LineCanvas.GetCellMap: Reuse intersection list outside nested loops GetCellMap would not benefit much from array pool because IntersectionDefinition is not struct. This change eliminates majority of the rest of Func<,> allocations. As a bonus IntersectionDefinition[] allocations dropped nicely. * Refactor local method UseRounded * Wrap too long list of method parameters * Region: Consistent location for #nullable enable --------- Co-authored-by: Tig <tig@users.noreply.github.com>
- The current, stable, release of Terminal.Gui v1 is .
- The current
prealpharelease of Terminal.Gui v2 can be found on Nuget. - Developers starting new TUI projects are encouraged to target
v2. The API is significantly changed, and significantly improved. There will be breaking changes in the API before Beta, but the core API is stable. v1is in maintenance mode and we will only accept PRs for issues impacting existing functionality.
Terminal.Gui: A toolkit for building rich console apps for Windows, the Mac, and Linux/Unix.
Quick Start
Paste these commands into your favorite terminal on Windows, Mac, or Linux. This will install the Terminal.Gui.Templates, create a new "Hello World" TUI app, and run it.
(Press CTRL-Q to exit the app)
dotnet new --install Terminal.Gui.templates
dotnet new tui -n myproj
cd myproj
dotnet run
There is also a visual designer (uses Terminal.Gui itself).
Documentation
The above documentation matches the most recent Nuget release from the v2_develop branch. Get the v1 documentation here.
See the Terminal.Gui/README for an overview of how the library is structured.
Showcase & Examples
Terminal.Gui can be used with any .Net language to create feature rich and robust applications.
Showcase is a place where you can find all kind of projects from simple examples to advanced real world apps that fully utilize capabilities of the toolkit.
The team is looking forward to seeing new amazing projects made by the community to be added there!
Sample Usage in C#
The following example shows a basic Terminal.Gui application in C#:
Example (source)
When run the application looks as follows:
Sample usage in F#
F# examples are located here
Installing
Use NuGet to install the Terminal.Gui NuGet package: https://www.nuget.org/packages/Terminal.Gui
Installation in .NET Core Projects
To install Terminal.Gui into a .NET Core project, use the dotnet CLI tool with this command.
dotnet add package Terminal.Gui
Or, you can use the Terminal.Gui.Templates.
