A web view for scheme
Composed from Windows 10 Web View 2 (win32) and Chez Scheme.
A native version that includes the webview is actively maintained
Selfie
This requires a very up to date Windows 10 version.
Reason
I prefer a workspace type interface rather than a terminal interface.
I like panes rather than overlapping windows; you can adjust these panes a little; there is an invisible splitter between them; you can drag that.
Usage
- Type in your scheme code; press control-return; the result is displayed below.
- Pressing shift-return will run a selected bit of code; I use that a lot.
If you write a function that uses display; that output goes into the wider transcript pane.
Although the text tiles are editable (thanks to code mirror) this is not an editor; visual studio code is a great modern editor for editing scheme and C++ code.
As well as executing scheme functions in the browser based view; you can also have the scheme functions create and execute any JavaScript in the web view; so that makes for reasonably unlimited potential.
The web view provides a communications channel; so that the browser and scheme can communicate directly.
There is still a web server; to load content; I always find browser controls are happier if you do not force feed them content against their natural flow and inclinations.
The image view; provides a canvas pane for drawing 2d graphics.
Limitations
I am using the single threaded version of scheme so it only ever runs one thing at a time.
Being linked to the browser control; certain function calls are going to be very asynchronous and possibly run in different threads; even so; only one thing will ever run in the scheme engine at a time.
Some features of Chez Scheme are deeply linked into the core of its terminal loving nature; and very hard to use outside of it; I have tried to redirect the traffic; but not intrusively. I do not modify Chez Scheme at all.
There is a Wiki here with notes.
Including a with pictures.
And other readme files; as I do write documentation.
- I use a modern version of windows 10; and a Visual Studio.
- The Microsoft document below; steps you through creating an app that embeds the web view controls.
- I use a web server that is a header only library; and some components that can be obtained using vcpkg; a C++ package manager.
- Will add a detailed build guide later.
