Live preview is totally blank

[shslave]

I'm not a tech guy, and am totally newbie both on vscode and asciidoctor. After a serial fresh installations, live preview get nothing at all. I really don't know where I went wrong, please help, thanks.

OS: Windows 10 (1809) Visual Studio Code: 1.33.1 Asciidoctor-vscode: 2.7.1 Ruby: 2.5.3 Asciidoctor: 2.0.9

[mkramers]

This is also happening to me:

AsciiDoc: 2.5.2

VSCode: Version: 1.33.1 (system setup) Commit: 51b0b28134d51361cf996d2f0a1c698247aeabd8 Date: 2019-04-11T08:27:14.102Z Electron: 3.1.6 Chrome: 66.0.3359.181 Node.js: 10.2.0 V8: 6.6.346.32 OS: Windows_NT x64 10.0.17763

Reverting to AsciiDoc v2.5.2 appears to resolve the issue

[MatteoCampinoti94]

That is very weird, v2.7.1 has been tested like the others and it doesn't add anything that could break the preview.

Since you are both using windows I do have an idea on what might be causing it, but it would happen only if you were using the new asciidoc.preview.style option and set an incorrect path.

@mkramers @yuatlas could you both share the asciidoc settings you are using? The ones in your global config and the ones in your workspace (if present).

Also, try doing this:

1. open your AsciiDoc workspace
2. open a command palette (F1 or CTRL+SHIFT+P) and select Developer: Toggle Developer Tools
3. try opening a preview and then copy paste the contents of the dev tools pane

Sorry for the problem :(

[bandersongit]

This is happening to me on macOS Mojave 10.14.4 as well

[danyill]

With Visual Studio Code 1.28.2 I get a blank screen with version 2.7.1 of the plugin.

I get this with using both asciidoctor.js and the system (Ruby) asciidoctor.

I installed 1.33.2 and had the same experience.

Here's an excerpt from the developer console output, some of which may be relevant:

[danyill]

At least in my case, asciidoc.preview.style is not set.

[danyill]

I looked at:

log.ts:173   ERR tokens.filter is not a function: TypeError: tokens.filter is not a function
    at AsciidocFoldingProvider.<anonymous> (C:\Users\mulhollandd\.vscode\extensions\joaompinto.asciidoctor-vscode-2.7.1\out\src\features\foldingProvider.js:29:42)
    at Generator.next (<anonymous>)
    at fulfilled (C:\Users\mulhollandd\.vscode\extensions\joaompinto.asciidoctor-vscode-2.7.1\out\src\features\foldingProvider.js:8:58)

If in foldingProvider.js I insert at line 29 return like so:

            const tokens = yield this.engine.parse(document.uri, document.getText());
            return;

Then my preview joyfully returns. Hopefully that is of some use.

[MatteoCampinoti94]

@danyill yeah that would close the foldingProvider function before it reaches the error point. It's not the cause of this issue however.

Found the culprit thanks to your log though ^.^

[MatteoCampinoti94]

The issue was caused by the vscode.workspace.workspaceFolders variable. It thought it would never be empty, always containing the folder Code has currently opened (even if you open a blank new window its workspace should be your user home), but I misread the documentation.

Added a small check to make sure that variable's elements are accessed only after it checks if it is undefined.

[MatteoCampinoti94]

Testing it a bit, then will update the version and flag it for release.

[MatteoCampinoti94]

@yuatlas @mkramers @danyill @bandersongit in the meantime you can install the extension directly with its *.vsix file: asciidoctor-vscode-2.7.2.zip.

1. Extract the .vsix file from the zip (Had to put it inside an archive since GitHub didn't allow me to post the vsix directly)
2. Go to the extension browser (CTRL+SHIFT+X, Mac CMD+SHIFT+X)
3. Click the small ... button at the top of the sidebar and select Install from VSIX...
4. Navigate to the extracted file and select it
5. Reload/Restart VSCode

[shslave]

@MatteoCampinoti94 Thanks for the help. The new testing version is blocked by MS Windows Defender, I don't know how. This is the detailed info from Defender.

And with version 2.7.1, here is the output from vscode dev tools console:

[MatteoCampinoti94]

Ah Windows, always finding new ways to be annoying x3 I guess it doesn't like to see Javascript files inside a zip with a custom extension. vsix files are just archives containing the packaged extension, nothing more. We dont even write the JS code, it's translated from Typescript by the packager.

Usually that file is downloaded and extracted by VSCode directly, but when you download something manually Windows gets really antsy.

Not really sure how to solve it, except to build it yourself. Sorry :(

The new version should be out soon though, so it might be just easier to wait for it ^^

[danyill]

Thanks for the speedy fix @MatteoCampinoti94 👏

[MatteoCampinoti94]

You're welcome @danyill ^.^

The new version was pushed out an hour ago, if no one encounters any errors I'll close the issue in the evening :)

Thanks to everyone for helping!

[danyill]

For future reference at least on Linux I can now click on settings and select install a different version which might be a good option to advise users on how to deal with issues which break behaviour and can't be immediately fixed.

Good idea @danyill, I'll add it to the readme :+1:

[mkramers]

The newest version (2.7.2) seems to resolve this issue for me. Thanks!

[MatteoCampinoti94]

@mkramers great! Thanks for the update ^.^

[MatteoCampinoti94]

Closing the issue since it seems to be solved for everyone.

Thanks again to everyone for the help in tracking down the problem!
