How to configure backgound preview in settings

[YinMo19]

Based on what you said about finding the built-in web preview feature in neovim's possibly incorrect typst configuration, I tried using the following configuration:

{
    "lsp": {
        "tinymist": {
            "settings": {
                "exportPdf": "onSave",
                "outputPath": "$root/$name",
                "preview.background.enabled": true,
                "preview.background.args": [
                    "--data-plane-host=127.0.0.1:23635",
                    "--invert-colors=auto"
                ]
            }
        }
    }
}

export pdf on save function runs well, but preview in background(which will serve on 127.0.0.1:23633) failed. If the plugin does implement backgound preview, how should I configure it?

The other question is, I know that the plugin does have very little buffer control over zed, and if this configuration works, is it possible to map code from browsers to zed? Otherwise, if the background preview is only limited to the preview function, then you only need to execute tinymist preview in the cli, which can be quickly executed using a zed task.

ohno ,I'm sorry that I should have modified my code directly in place just now. I meant that there was no problem(like typo) with my actual configuration, but there was a typo when I entered the github issue(I fix it in place already), and other problems were the same, as the background preview and more. (I'm a China user, and my English level is bad, sorry!!)

Thanks to your help!

I'm having the same issue as you. What was your final code that worked?

[YinMo19]

Why is my supplementary question considered an answer? I still haven't found the code that ultimately works. Perhaps this feature is not yet implemented, I will consider the cli preview function for the time being.

[seb-hyland]

Oh sorry, I misunderstood. I found that

  "lsp": {
    "tinymist": {
      "initialization_options": {
        "preview": {
          "background": {
            "enabled": true
          }
        }
      }
    }
  }

works for preview. I haven't found a way to successfully pass arguments for some reason though.

I also have not been able to set the arguments! There have been some other discussions around a similar issue which I think mention the correct format: #21.

However, this still didn't work for me. This becomes an issue in MacOS and devcontainers (we finally have devcontainers!) as host doesn't work because docker desktop runs through a VM. If it's of use to anyone, I've used socat to bypass the issue:

{
    "name": "Typst Development Environment",
    "build": {
        "dockerfile": "Dockerfile"
    },
    "remoteUser": "vscode",
    "appPort": [23634],
    "postStartCommand": "socat TCP-LISTEN:23634,bind=0.0.0.0,fork TCP:127.0.0.1:23635 &",
    "features": {}
}

Not necessarily an answer to the question, but might be useful if the listening address is an issue.

Forgot to say, I can pass arguments by these config in settings.json

        "tinymist": {
            "initialization_options": {
                "preview": {
                    "background": {
                        "enabled": true,
                    },
                },
            },
            "settings": {
                "formatterMode": "typstyle",
                "formatterIndentSize": 4,
                "exportPdf": "onSave",
                "outputPath": "$root/$name",
                "preview.background.args": [
                    "--data-plane-host=127.0.0.1:23635",
                    "--invert-colors=auto",
                ],
            },
        },

this works! @seb-hyland Sorry for a long time, I found this solution many months ago but I forgot to post this setting here.

[bingbongboink]

This solution doesn't work for me for whatever reason. Not sure why.

[YinMo19]

do you have already install the tinymist cli? which means, you should ensure you can work with tinymist cli in background and this config just simplify this.

[YinMo19]

It is my success case and log.
