Preview fails with error (unable to open \Preview) about asciidoctor-vscode

[arulrajnet]

Found the problem. I am using another extension for reStructuredText. That causing the problem. After disable that its working fine. Thanks for this nice extension

Help -> Toggle Developer Tools helped me to find the exact issue instead of Debug console of vscode.

PS: Just to let you know. It's working great now. Thanks for the good work, João!

Hi, please try: View -> Debug Console, and then press the CTR-K r, hopefully it will report the error on the debug console.

[NenoLoje]

Thanks for the suggestion. I tried, but unfortunately the Debug Console remains empty. :(

[joaompinto]

Right, so let's do some requirements check, this extension requires "asciidoctor", are you using Windows or Linux ? Does "asciidoctor" on a terminal/command prompt work ?

[NenoLoje]

I'm running on WIndows.
Asciidoctor is installed, but possibly it's not defined in the PATH.

How are you detecting asciidoctor?

[NenoLoje]

I think this is it. When adding the ruby/asciidoctor folder to %PATH%, it works as expected.

Maybe you could:
(1) Handle the detection error more gracefully, in cases where asciidoctor is not installed or %PATH% not set correctly.
(2) Optionally, be more flexible and allow users to set the path and not rely on %PATH%.

[joaompinto]

Neno,
you can setup the path in the extension config.
File -> Preferences -> User Setttings,
you need to copy the required setting into your local config:
"AsciiDoc.html_generator": "YOUR_PATH\asciidoctor -o-" .

Anyway I will let this issue open, will close it with after adding the code for your suggestion (2), it should report that asciidoctor is missing from the path.

[NenoLoje]

Sounds good - thanks a lot, João!

[joaompinto]

PS: Thanks for reporting. The error message with a suggestion for the path config was added on the new version.

I am getting the same error in ubuntu 16.04.

Asciidoctor 1.5.4

PATH of asciidoctor bin /usr/bin/asciidoctor

asciidoctor -o- 1-introduction.asc prints html on terminal.

there is no error in vscode Debug console.

I had Restructured Text previewer installed. Disabling the plugin solved the issue. Thanks !
