feat: Draft fledgeling object, ready for internal use

[krlmlr]

Closes #402.

TODOS

• Also parse h2 for version (see pkgdown)
• tests

[krlmlr]

@maelle: Can you please pick up from here?

[maelle]

@krlmlr I added a bit more parsing, and tests, you can now review this.

[maelle]

Working on writing should happen after both this and #584 are merged, but I'm working on paper in the meantime.

I feel parsing the news a bit more should happen now too.

[maelle]

why is the object immutable, more specifically, why not copy more of desc logic?

[krlmlr]

Thanks. The h2 detection is broken, but we also don't need it here. Can you please remove it? Parsing the individual h1 sections would be done on demand, later.

[krlmlr]

Maybe I misunderstood h2.

[krlmlr]

Can you share an example NEWS file where the h2 detection is triggered?

[krlmlr]

The original column should perhaps contain the entire section, including empty lines. Perhaps as a single character string, with embedded "\n" ?

[maelle]

why would the header and content be stored together?

[krlmlr]

Should the class name be "fledge_ling" ? So that the package name still is the prefix?

[krlmlr]

I have code that also extracts the preamble: https://github.com/cynkra/fledge/tree/f-402-fledgeling-3 .

Should the class name be "fledge_ling" ? So that the package name still is the prefix?

but what about method names?

[maelle]

I have code that also extracts the preamble: f-402-fledgeling-3 .

why not add it to this branch?

[krlmlr]

To avoid conflicts with your work. Pushing now.

[maelle]

ok, sorry, I'm experimenting with Pandoc in no branch :-)

[krlmlr]

Also keeping raw text now for preamble and all sections. We can do a perfect roundtrip with this object now, and should start using it everywhere in the codebase.

[krlmlr]

Fixed corner case with empty preamble.

Ready for review, talk soon!

[maelle]

should this be merged?
