Conditional env for vscode in asciidoc: how to detect we are in vscode preview

[prudhomm]

I am writing pages in asciidoc for an Antora website.

I wish to visualise the images in preview. The images are not in the same directory as the adoc file

Is your feature request related to a problem? Please describe

How do I detect that I am in vscode (preview) to display images ?

:imageprefix: 
ifdef::env-github,env-browser[:imageprefix: ../../assets/images/]

work fine at top of doc in github.

Describe the solution you'd like

would it be possible to have something like

:imageprefix: 
ifdef::env-github,env-browser,env-vscode[:imageprefix: ../../assets/images/]

or maybe there exists already an env- that catches that we are in vscode preview?
I would have expected env-browser to work.

here is an example of an adoc file in an antora framework:
I can see the images in github
https://github.com/feelpp/toolbox/tree/master/examples/modules/cfd/pages/laminar_isothermal_backward_facing_step
as well as in the browser thanks to the asciidoctor.js browser extension

Thanks for logging this issue @prudhomm, I think we could set an attribute in vscode to detect this -- something like env-vscode or similar. Happy to take a PR, although I hope to deal with some of these easier issues quite soon.

Thanks a lot

@danyill @joaompinto it works very well.
for the record, here is what +I did:

top of the document, / at the end

ifdef::env-github,env-browser,env-vscode[:imagesprefix: ../../images/]

where I add an image, no / at the end

image::{imagesprefix}myimage.png[]
