Feature request : textDocument/inlinedAnnotation

[angelozerr]

I create this issue according my skills with Eclipse CodeMining which does the same thing than CodeLens but gives too the capability to draw content inside the line content (like color information used by CSS and JSON LS)

Takes a sample with Eclipse CodeMining:

• here a CodeMining for JUnit: it is drawn by a line header annotation with an icon and text

• here a CodeMining for parameter names for Java method: it is drawn by a line content annotation:

In other words I tell me if LSP could mix CodeLens and ColorInformation inside the same concept that it is called Inlined Annotation in Eclipse Platform.

Today LSP provides capabilities to support:

• code lens which is drawn before the line text (line header annotation).
• color information which is drawn in the line text (line content annotation)

IMHO, I think we could improve

• CodeLens to specify an icon (or emoji)
• Having a more generic concept than ColorInformation to draw anything in the line content annotation.

We could have an inlined annotation composted by:

• text
• icon (image name, or rgb color)
• type : header (annotation drawn in the line header) or content (annotation drawn in the line content)

Here Inlined annotation benefit:

• havejust one concept to manage CodeLens and ColorInformation both
• improve CodeLens to draw an icon before the text
• gives the capability to draw text/icon inside the line content (support for ColorInformation and other features like parameter names for Java method)

Couldn't we just generalize codelens response message to add some "insertionType: header | inline" ?
