Fill-paragraph (M-Q) in a reStructuredText document that is formatted
using "Line Blocks"
<https://docutils.sourceforge.io/docs/ref/rst/restructuredtext.html#line-blocks>
such as:
| In Xanadu did Kubla Khan
| A stately pleasure-dome decree:
| Where Alph, the sacred river, ran
| Through caverns measureless to man
| Down to a sunless sea.
results in this:
| In Xanadu did Kubla Khan | A stately pleasure-dome decree: | Where
Alph, the sacred river, ran | Through caverns measureless to man |
Down to a sunless sea.
but in this case it should leave the line breaks intact. The code
should probably treat the vertical bars something like list bullets,
since continuation lines are possible, e.g.
| This is the all the first line
of output even though it's two lines
of input.
| This is second line in the output.
| And this is the third.
(I searched <https://debbugs.gnu.org/cgi/pkgreport.cgi?package=emacs>
for a similar report. Apologies if I was not thorough enough.)

OTOH line blocks are really a rarely used feature I guess, so it doesn't hurt much. I'll look deeper into the code. But don't hold your breath ;-) .

[ With all those Stefans around I feel like nothing can stop us. ] I think we "just" need to: - set `paragraph-start` to match a line with a leading `|`. - set `adaptive-fill-regexp` to match this leading `|`. If the `paragraph-start` setting makes paragraph navigation inconvenient (too fine-grained), we could try and set `fill-forward-paragraph-function` to a function which let-binds `paragraph-start` around a call to `forward-paragraph`.

If that's bug#24081, then I don't see any rejection there, only a request for clarification (which you gave). Then the bug was for some reason closed several months later, with no rationale. We could reopen the bug, of course (assuming it still relevant to current versions of Emacs 30 and 31). But that bug is about message-mode, not about rst-mode, so I'm not sure it is the same problem. ^ permalink raw reply [flat|nested] 15+ messages in thread

That bug is archived, so we cannot discuss anything unless we unarchive it. But we can stop discussing that here, since it's a separate issue.

Sorry, but it's not that simple. The syntax of reStructuredText is pretty tricky and it needs lots of good ideas to handle it. But it's nice to write and read - and that's is why it IMHO is still a worthwhile alternative. If it would be as simple as you suggest, I would have built it in from the start. There is a reason for not doing it. Indeed line blocks were at the end of my list of supported reST features because I think they are used rarely. The function `rst-line-tabs' has a FIXME comment: ;; FIXME: Must consider other tabs: ;; * Line blocks ;; * Definition lists ;; * Option lists I guess the real problem is in that second line, that line blocks are not yet supported. I'll look into this. Grüße Stefan ^ permalink raw reply [flat|nested] 15+ messages in thread

Not in my test, no. With a paragraph like: | bblblbl | asdfasdf | asdasdf M-: (and (looking-at adaptive-fill-regexp) (match-string 0)) RET returns a string that contains only the leading spaces. `paragraph-start` doesn't match those lines either.

[-- Attachment #2: verse-test.rst --] [-- Type: text/x-rst, Size: 2694 bytes --] ================ Bug 74785 test ================ This is a test file for `GNU Emacs bug 74785 <https://debbugs.gnu.org/cgi/bugreport.cgi?bug=74785>`_, created to help clarify the issue and help developers test solutions. It's not exhaustive. You can check the output easily with rst-compile (C-c C-c C-c). It would be nice if selecting the *entire* document and executing fill-paragraph would result in a document that is: 1. filled and wrapped nicely as a text source 2. has unchanged output. Example one. In the simple case, as a top-level block. | In Xanadu did Kubla Khan | A stately pleasure-dome decree: | Where Alph, the sacred river, ran | Through caverns measureless to man | Down to a sunless sea. Example two. Here's the same thing as a quote. | In Xanadu did Kubla Khan | A stately pleasure-dome decree: | Where Alph, the sacred river, ran | Through caverns measureless to man | Down to a sunless sea. -- Samuel Taylor Coleridge Example three. With continuation lines, this should produce identical output to the previous example. | In Xanadu did Kubla Khan | A stately pleasure-dome decree: | Where Alph, the sacred river, ran | Through caverns measureless to man | Down to a sunless sea. -- Samuel Taylor Coleridge It would be nice if fill-paragraph (M-q) would reformat example three to look like example two. Example four. Conversely, here's a verse with long lines beyond the default fill column of 70. | Begins the night’s shadows creeping, his eyes mocking, and beseeching. | I must stop his soul from joining, to fight with Poes’ shadows trying… | Trying once more, to take his soul, toward those demon littered shores. | Grabbing the ipod I forward tore, to give him tranquility evermore. | Pouch and ear buds firmly seated, engaged in a fierce-some war. | Morning found all, in blissful snores… Quoted the raven nevermore. -- Carol Eastman Example five. It would be nice if fill-paragraph would wrap these lines, but in a way that keeps the output identical. For example (with fill-column 70): | Begins the night’s shadows creeping, his eyes mocking, and beseeching. | I must stop his soul from joining, to fight with Poes’ shadows trying… | Trying once more, to take his soul, toward those demon littered shores. | Grabbing the ipod I forward tore, to give him tranquility evermore. | Pouch and ear buds firmly seated, engaged in a fierce-some war. | Morning found all, in blissful snores… Quoted the raven nevermore. -- Carol Eastman Of course all of the above must work when nested within other forms. Thanks all. .. end ^ permalink raw reply [flat|nested] 15+ messages in thread
