raw.flattenPath equivalent

[capsloq]

First of all great substitute for contentlayer thank you for that. I am testing out velite by migrating a contentlayer project.

In contentlayer my slugs were based on the filepath. For a nested MDX file in e.g. content/firstfolder/secondfolder/test.mdx that meant the slug would be /firstfolder/secondfolder/test

To achieve that in contentlayer we had raw.flattenedPathlike

const computedFields: ComputedFields = {
  slug: {
    type: "string",
    resolve: (doc) => `/${doc._raw.flattenedPath}`,
  },

I did read the velite documentation but how would that be achieved in velite? I understand you can either use .transform for collection based computed fields or prepare for all collections.

If there is a solutions to this might consider adding it to the docs

Thank you

Answering my own Question:

There is a context object as an argument within transform:

 schema: s
        .object({
          title: s.string().max(99),
          ...

        })
        .transform((data, ctx) => ({ ...data,
          // computed fields 
          permalink: `/${data.slug}`,
          fileInfo: ctx.meta.file.path,
          fileInfo2: ctx.meta.file.basename,
          fileInfo3: ctx.meta.file.dirname,
          fileInfo4: ctx.meta.file.extname,

        }))

Still suggesting to add an example to the docs for "file based slugs" so folks migrating from contentlayer have it easier

Yup, but it is recommended to use file.stem, which is more similar to flattenedPath.

refer to VFile.stem for more details.

path: s.path()
// => flattened path, e.g. 'posts/2021-01-01-hello-world'
