Re: irrational meters
Hello Silvain, this is only true if you define a "rational meter" to be a meter which evaluates to a rational number. Note that a Time Signature is NOT a rational number, else 3/4 and 6/8 would be equivalent. And similarly to how a rational argument is not an argument that corresponds to a rational number a rational Time Signature can have a different meaning to a rational Number. Of course this does leave the question open of what exactly *is* a rational Time Signature. And would it even make sense to use a Time Signature that is not rational? Valentin Am Dienstag, 17.

Re: irrational meters
Thank you Valentin,
In fact i am now using the solution #1 which gives correct time settings. By
the way i am using this in a "poly-metric" and "poly-tempic" context, and i
must say it works good. Only possible in Lilypond. Thank you to all developpers
and expert users for all your work and advice.
I am sorry i have unleashed an off topic disscussion, however, i appreciate all
your remarks which testify of your passion to music, music theory and
typesetting.
Take care all of you.

autobeaming over rests
The NR says that autobeaming doesn't work over rests. In some situations this means a lot of additional work. As an example, consider a piece that uses almost exclusively a saltarello-like rhythm: ``` \time 6/8 d8[ r d] d[ r d] ``` I now wonder whether it makes sense to control this behaviour with a property, and whether this behaviour (i.e., autobeaming over rests) can be easily implemented at all...

True, but time signatures do not have a 1-to-1 correspondence with rational numbers: 6/8 and 3/4 are distinct as time signatures, even though as fractions they signify the same rational number. > Now if we wanted to think about time signatures N/D where N and D are > elements of, say the integers with the square root of -5 adjoined, > that's another matter. Any takers, you composers out there? :) [...] Adjoining square roots of some positive number may still be somewhat imaginable, e.g., √5/4 means each measure consists of √5 (approximately 2.236...) quarter notes. Hard to perform precisely without computer help, but still possible in theory. But how is one to interpret √(-5)/4 ?? How do you count up to an imaginary number of beats per bar, even in theory? // Further thoughts about √5/4 as a time signature: due to the peculiarity of standard musical notation, which only has symbols for note values that are rational subdivisions of a whole note (and even that, not all rational subdivisions are directly representable), any combination of notes in a √5/4 bar will not fit exactly within the bar, √5 being irrational. (This also applies to any other irrational fraction you may choose for the top component of the time signature.) So that means the last quarter note beat will be split across the bar line by some irrational fraction, with the remaining duration overflowing into the following bar. Note that changing the notation may not help anything. Suppose we introduce new notation for representing irrational note values. Then either the new note values are commensurate with the (irrational) time signature, or they're not. If they are, then we've effectively reduced the time signature to a traditional, rational signature: if we introduce a note value of √5/6, for example, then 6 such notes would add up to 1 bar in a √5/4 signature, so we've effectively turned it into 6/4 and it's no longer an irrational time signature. If the new note values are not commensurate with the time signature, then we will still have notes split across barlines even if we use the new note values, so nothing has really changed. Now if you have a long series of consecutive quarter notes, they will span some number of bars, and every bar line will split a quarter note in some unique, irrational fraction -- due to irrationality, no bar line will fall exactly at the start/end of a quarter note, so excepting the start of the first bar, everywhere else there will be notes split across the barline. And each split note will be split in a unique, irrational fraction. If we individually move each barline so that it falls on the closest start/end of a quarter note, then we end up with a series of bars with regular (rational) time signatures, but with time signature changes in an irregular pattern -- this is what I referred to in an earlier post. So, "rationalizing" an irrational time signature in this way, we see the irrational number essentially serves as a source of irregular bar lengths that never repeats.

Auto-transpose engraver progress
Hi all, I managed to add functionality to the auto-transpose engraver snippet from OLL so that it prints key signatures at transposition changes. It also doesn't do so if the transposition change is only octave transposition. The one thing I'd like to fix is the behavior when an actual key change occurs at the same moment as a transposition change. Currently this triggers a warning and the output is only correct depending on whether the key change or transposition is written first. Not sure how to approach solving that. Saul auto-transpose.ily Description: Binary data
Re: Auto-transpose engraver progress
Thinking about this more, the issue with simultaneous transposition and key
changes is worse than I realized, since it's pretty common to write
something like:
global = {
s1
\key e \major
s1
}
music = {
g'1
\transposition a
g'1
}
\new Staff \with {
\autoTranspose
} <<
\global \music
>>
The output is incorrect (but differently wrong) regardless of whether you
write << \global \music >> or << \music \global >>.
This is partially a bug in the original snippet, not just my version with
inserted key signatures. Solving it would seem to require the ability to
"listen ahead" or "listen behind" to all the events happening at the same
moment. Is that even possible?

Documentation viewer in Frescobaldi
Frescobaldi 3.2 on Linux (EndeavorOS, and Ubuntu), no matter what URL or local file I put in the Lilypond Documentation preferences it does not work. If I use a URL at lily[pond.org I get an Apache error. If trying to add a local copy the index.html file simply does not appear in the browser dialog when I go to the appropriate directory. I am mystified. Any clues? When I install Frescobaldi it does show doc for 2.22 online but nowhere do I see this URL in the preferences, so how does it even get there? Hardwired? Does not seem right.

I don't use F~ so I don't know what the Preferences or Configuration
Dialogue would expect to be fed with.
However, I do see¹ /usr/share/frescobaldi/frescobaldi_app/lilydoc/manager.py
contains these lines:
# split in local and non-local ones (local are preferred)
user_prefixes = []
local = []
remote = []
for p in user_paths:
user_prefixes.append(p) if os.path.isdir(p) else remote.append(p)
remote.sort(key=util.naturalsort)
# now find all instances of LilyPond documentation in the local paths
def paths(path):
"""Yields possible places where LilyPond documentation could live."""
yield path
path = os.path.join(path, 'share', 'doc', 'lilypond', 'html')
yield path
yield os.path.join(path, 'offline-root')
def find(path):
"""Finds LilyPond documentation."""

return p
> When I install Frescobaldi it does show doc for 2.22 online but

and later:
urls = []
urls.extend(map(QUrl.fromLocalFile, local))
urls.extend(map(QUrl, remote))
if not urls:
urls.append(QUrl("http://lilypond.org/doc/stable";))
return urls
so it appears to have a fairly thorough hunt for the docs.
(I assume urls.extend is reading some Configuration data.)
¹ F~ 3.1.3 from Debian buster. I don't remember whether I ever ran it;
perhaps I replicated someone's post. I haven't downloaded F~ on bullseye.

Re: Documentation viewer in Frescobaldi
The strange thing is that this used to work fine in the past, and now coming back to it after six months it does not. It is very strange that on two distinct Linux distros it shows the same behaviour. It's weird that the fill chooser dialog won't show .html files (and no, they are not hidden files). Strange. And I'd still like to know how F mysteriously display the 2.22 documentation page, with no settings indicating that. Stupid to even try, but reinstalling F made no difference. Where is actually the best place to post about Frescobaldi support nowadays? Andrew

Nice idea, thanks! However, this is far from a convenient solution in
the long run. IMHO, there are definitely valid situations where
automatic beaming over rests does make sense.
Looking up our tracker, this is actually issue #994.
