Recreate "Export Slide Deck" command in CLI

[connortsui20]

Is there a way to recreate the "Export Slide Deck" command in VSCode directly in the marp CLI? I can't seem to figure out the exact flags needed for this.

You can peek internally running CLI flags while exporting in the developer console of VS Code (Help -> Toggle Developer Tools). The logic of generating configuration file can check at https://github.com/marp-team/marp-vscode/blob/5f133ea8efa6bff2a91ab2c74e560b195610cfd5/src/option.ts#L113

Thanks for the reply! Is there a way to intercept the config JSON? It looks like the command uses -c /tmp/.marp-vscode-cli-conf-fTId0nf364Hd0BIWsruvH.json, but I have no way to view that config file.

No. That is a temporary file and will be removed as soon as the export is complete.

Again, you can peak how to generate CLI configuration file in https://github.com/marp-team/marp-vscode/blob/5f133ea8efa6bff2a91ab2c74e560b195610cfd5/src/option.ts#L113. Only the code is a reliable source.

Yes I can read the code but understanding what it is doing is a different story. It's not obvious to me what this configuration file should look like, and looking at this code it doesn't seem like the logic for what goes in the config file is here anyways?

Is there a way for me to log something in this code to see what exactly is going on? I'm not familiar with VSCode extensions so I'm sort of clueless here...

[yhatt]

Either approach requires the skill of the front-end development. The mentioned function will be called at here, stored the generated configuration into JSON file, and used it as Marp CLI arguments at the export command.

You also can modify the source code to record the log, rebuild the extension, and use the custom VSIX in your VS Code. However, Marp team does not have any responsibility for the custom build.

A simple configuration looks like this:

{
    "allowLocalFiles": true,
    "pdfNotes": false,
    "pdfOutlines": false,
    "html": true,
    "browser": "auto",
    "options": {
        "markdown": {
            "breaks": true,
            "typographer": false
        },
        "math": "mathjax"
    },
    "pptxEditable": false,
    "themeSet": ["<absolute path>"],
    "vscode": {
        "themeFiles": [
            {
                "path": "<absolute path>"
            }
        ]
    }
}
