add imagesdir setting in asciidoctor attributes when antora is enable

[man-chi]

problem: many users of asciidoctor would like to use antora as HTML site generation. however, the default image directory structure will be /docs/ROOT/module/images while the *.adoc are stored in /docs/ROOT/module/pages.
due to the vscode webpreview permission setting, web preview is unable to display any image::diagram.jpg[my diagram]

proposed solution:
as a workaround before Antora is fully supported, I managed to preview images in vscode-asciidoctor web preview by doing the following setting in vscode web preview:
• vscode-asciidoc extension > settings > asciidoc >preview : asciidoctor attributes
• Edit in settings.json
"asciidoc.preview.asciidoctorAttributes": {
"imagesdir":"../images/"
}

I want to suggest presetting the settings.json
"asciidoc.preview.asciidoctorAttributes": {
"imagesdir":"../images/"
}
when the Antora checkbox is enabled in the extension setting

It should already work if you enable Antora support. Here's an example:

[man-chi]

it is odd. the image does not preview by default. unless add the following imagesdir entry in settings.json
"asciidoc.preview.asciidoctorAttributes": {
"imagesdir":"../images/"
}

@ggrossetie is your vscode a specific version? nightly build? anything we need to do?
I am running vscode Version: 1.87.2
vscode-asciidoc extension v3.2.0

[ggrossetie]

Do you have "asciidoc.antora.enableAntoraSupport": true in your settings? Did you get a popup asking you to enable Antora support?
Do you have an antora.yml file with a name and version? Do you have a valid Antora structure?

I'm using version 3.2.0 of the extension:

Version : 1.86.0 (Universal)
Validation : 05047486b6df5eb8d44b2ecd70ea3bdf775fd937

Système d’exploitation : Darwin arm64 23.2.0

[man-chi]

yes, in my Code/user/settings.json, I do have

"asciidoc.antora.enableAntoraSupport": true,

Did you get a popup asking you to enable Antora support?
I recalled that there was a dialog box showed up before but I did not manage to click yes. afterward, I do not have any opportunity to see the option again. how can I see the popup again?

I do the antora.yml file and I have been using antora site generation successfully for the past few months.
the structure is the standard of antora, such as

antora.yml

title: Main
name: main
version: ~
nav:
  - modules/ROOT/nav.adoc
asciidoc:
  attributes:
    page-pagination: ''
    experimental: ''
    idprefix: ''
    idseparator: '-'

@man-chi We save this setting in the workspace state but as far as I know there's no easy way to reset this state. You will need to delete files from your disk:

<user-data-dir>\User\globalStorage\state.vscdb
<user-data-dir>\User\workspaceStorage\<workspace.id>\state.vscdb

Depending on how VS Code was launched you could have a Single Folder Workspace or a Multi-Folder Workspace that is global or local. Globally, the data lives here:

Linux: $HOME/.config/Code/
OS X: $HOME/Library/Application Support/Code/
Windows: %APPDATA%\Code\

If you reset the workspace state and open nav.adoc the popup should show again. I think we need to add an action to activate/deactivate Antora on a workspace.

The setting "asciidoc.antora.enableAntoraSupport": true is here to enable Antora but then you need to activate Antora per workspace.

[ggrossetie]

I think I will do the following to make it easier to activate/deactivate Antora.

• Replace the current user/workspace setting by "Show a prompt to enable Antora support when an antora.yml file is detected". yes/no
• Add a command to toggle Antora support on a given workspace (saved in Memento)

That way you can control if you want a prompt when the extension detects an antora.yml file. And you also have the ability to enable/disable Antora support using a command (in case you clicked "no" on the prompt or in case the extension didn't detect the antora.yml or in case you want to turn it off)

@man-chi What do you think?

[man-chi]

yes, it sounds awesome. thanks for making such improvement. I love antora.
