How to use `vivliostyle.config.js` without `entry`

[cmahnke]

I'm trying to convert multiple HTML to PDF using a shell script. Additionally I need use vivliostyle.config.js to pass options like static (see #661 for background). But vivliostyle won't work if vivliostyle.config.js doens't contain an entry. Is there a known workaround?

ERROR Validation of vivliostyle config failed. Please check the schema: undefined
Invalid key: Expected "entry" but received undefined

Setting a dummy won't work, it's then used instead of the input file given as input.

@cmahnke I apologize for the late response, as I was late in noticing this issue.

What kind of HTML file are you trying to convert to PDF? You can specify both HTML and Markdown files as input. Please try setting the path to your desired HTML files in the entry option.
Also, you might be able to solve the problem you're facing by referencing the HTML file directly by specifying an entry with a path that starts with /, which allows you to reference HTML files in the directory specified by the static option.

That's the issue: I don't want to hard code the input file, since I don't know it in advance: I want to generate HTML files using Hugo since the workflow is already in place for my website. Afterwards I plan to use a script wrapper that generates PDF from a few of the resulting files. I guess the main issue is currently that vivliostyle-cli is not very good in converting just a bunch of stuff (a HTML with referenced CSS and JS into PDF from the local file system, see #661) into PDF.
So actually this can be closed if the priority of #661 get's risen. Another approach would be making the config optional: From my point of view a config of a command line tool should be designed in a way that it's just for presets for options. That is one can't set anything in a config for which there is no CLI switch...
