But I looked for more and thanks to a little tip from Norman on my visit in September, I got pointed to the Scintilla project. That is am open source C++ library defining an editing component, which we can host in a plugin based Xojo control: ScintillaControlMBS
The description from their website shows what we may get in Xojo:
We may not get all things right into the control for the first release, but since the control seems to work fine for macOS and Windows already, I am confident we can ship this as a 1.0 with our next plugin release in January. There is still a long todo list, but we like to give interested developers a preview. Please try it in next pre-release.
As well as features found in standard text editing components, Scintilla includes features especially useful when editing and debugging source code. These include support for syntax styling, error indicators, code completion and call tips. The selection margin can contain markers like those used in debuggers to indicate breakpoints and the current line. Styling choices are more open than with many editors, allowing the use of proportional fonts, bold and italics, multiple foreground and background colours and multiple fonts.
Things we may do later, if possible include support for Linux. Maybe we can provide the library within the plugin instead of an external library. And we may improve the API to be more Xojo like, add printing functions, marker pictures or async loading.
Please try it in the next days and let us know what you think!
