Suggestion: Implement a non breaking way for page locking.

[exjaynine]

I have a proposal. There is no built in means in the spec for page locking, but what if we allowed pages to be 'locked' that won't break things in other editors. Any page that needs to be locked, add a boneyard directly next to the page break === or the scene such as /*Locked*/ literally spelt that, and it can renumber everything following scene 2 as 2A, 2B, 2C.

How would that work with fountain-mode?

At the moment the only implementation is that the page break regular expression allows for the forced page break:

=== 7 ===

So calling fountain-forward-page (C-x ]) will stop at that page page break.

There are two functionalities yet to be implemented:

1. When the script has forced page breaks we want to be able to navigate to the correct page, e.g. given the above when navigating to page 8, point should go to one page after the forced page break.

2. Correct page numbering when calling fountain-export. (n.b. I can't control how external programs will handle page breaks with fountain-export-command.)

The reason I haven't implemented this is that although I feel like we reached a consensus for the syntax on the fountain-dev mailing list, the syntax was never officially adopted. And John seems to have moved away from an official spec with Highland. I'm not sure what the story is here and I don't really want to push.

If the response I get from https://github.com/rnkn/fountain-mode/discussions/144 is positive I will try again to get forced page numbering adopted in other Fountain apps.

I've added the original suggestion and relevant feedback here: https://github.com/rnkn/fountain-mode/discussions/145

The question of how this will permit page locking, I think if X- headers are adopted, we simple insert forced page breaks then add one of the following:

X-Locked: yes
X-Fountain-Mode-Locked: yes
Locked: yes

Interesting, if this does go through, does that mean revision colors are also a possibility?

Kinda depends on how you see that working. Do you mean just syntax highlighting or something semantic to the content?

Btw upon a closer read of the spec it turns out the X- header idea is redundant; any unknown header is supposed to be ignored.

I realise I didn't really respond to this. The pagination logic is already there, it's how the fountain-export-troff paginates before converting to troff, essentially going through the script and inserting page breaks where appropriate. You can try it yourself with:

(goto-char (point-min))
(while (< (point) (point-max))
        (fountain-move-forward-page)
        (unless (eobp)
          (fountain-insert-page-break)))

It's just a matter of me implementing the user-facing parts.

If I could add to the revision marks discussion, textplay uses diff files for adding in what to consider a revision mark and when converting to HTML or PDF, it colorizes that.

@sattelitecr as far as the internal PDF export via Troff goes, Troff has the request .mc which puts a character in the right margin, e.g. *, so it's doable. I think it will be a case of doing a diff between two buffers, stripping out the deleted lines and putting text properties of the added lines, then wrapping these lines in the .mc request on export. I just have to get around to doing it.
