problem with hacklily

[Stefan Thomas]

Dear community,
I wanted to save a file in hacklily (https://www.hacklily.org/).
Unfortunately I can't do this, I always get

> TypeError: e.sent map is not a function.
>
I should mention that I use the firefox browser.
Has someone an idea what could be wrong?
Thanks,
Stefan

Yes, this one's the longer one, so I'll comment on this.

I'm not sure why EDITOR is preferred to LYEDITOR. As far as
point-and-click is concerned, they have the same effect¹. But
exporting EDITOR has the consequence that it overrides all
other places where EDITOR is used.

The intention behind having the three variables LYEDITOR/XEDITOR/
EDITOR is that LYEDITOR can specify one editor for LilyPond's
point-and-click, XEDITOR can specify another (say, graphical one)
for any time that X is running, and EDITOR can specify a text-based
backstop for when X is not running.

I think Federico Bruni pointed out that libgnome2-bin/gnome-open is
rather historical, in favour of xdg-open (usually in xdg-utils).
I guess that might be something worth changing in the Usage manual.

This is the step you were going to edit out of your crib,
the reason being

and /etc/apparmor.d/usr.bin.evince is such a base file.

But I think your earlier comment on the trailing comma would be
worth adding to the Usage manual.

Interestingly, on Debian² you don't even have to bother to start gvim
at all *unless* you want to edit with vim, in which case

$ vim --servername gvim

will start a text server version wherever desired. Otherwise,
(graphical) gvim will start automatically. (I'm assuming that
vim/gvim are both installed, as would be usual.)

lilypond-2.21.0-1.linux-64/lilypond/usr/share/lilypond/current/scm/editor.scm

  (getenv "XEDITOR")
  (getenv "EDITOR")

  ;; FIXME: how are default/preferred editors specified on

I see the problem, but I think that solution is unwise as it leaves
a redundant file in the user's home directory, which they may fear
removing. Better would be to improve the Usage manual in a way such as:

--✄--
  and then execute the commands

xdg-desktop-menu install /tmp/lilypond-invoke-editor.desktop
xdg-mime default lilypond-invoke-editor.desktop x-scheme-handler/textedit

  where /tmp is the directory that was chosen for the file.
--✄--

At present, the Usage manual switches from /tmp/ to ./ without
explanation. The idea of using /tmp for the scratch file is of course
that it's automatically emptied when you reboot.

This script then has to be maintained, and it also makes it less obvious
how to adjust the process for any differences between systems. I think
the process is mysterious enough without hiding it any more.

So what sort of lag are you talking about? And is it different on the
first click (ie when the source file has to be opened)? You must be
running on reasonable hardware, so a noticeable lag does not seem
at all reasonable. A data point for you:

Debian 10/buster with Xpdf and emacs running on a 2000-vintage
Pentium III at 650MHz in 512MB memory took less than a second to
open the source at the first click, and thereafter serviced each
click in 0.5 secs, just so long as the new target position is in
the displayed window. (Obviously this machine takes at least a
second or two to scroll any distance in the editor, and at least
a second just to turn a page in a simple image-free PDF file.)

Cheers,
David.

Thanks, Aaron, but I specifically asked about 2.21.80 because of Phil
Holmes' request for users to use the "stable release candidate", or
2.21.80. I'm currently running 2.20.0. I could not find adequate
instructions for installing the unstable version.


That's the point.  It's all the same.  There's no unique instructions

You are using pip2 (python2) installed in ~/.local, but you're trying 
to install a py3 wheel.
pip2 install seems to try to install under /usr/local by default¹, but 
it won't work unless you use sudo.



I would try:

pip3 install --user setuptools


¹ pip3 is smarter and doesn't need the --user switch if called as

Hi Aaron,

thanks for your suggestion, hopefully the author of said snippet will read it.
Usually I try to contact the author to discuss such things with him or her.
Only if not available I will step in myself.

Re: Lilypond and Python

[Martín Rincón Botero]

Hi Stefan,

it seems the updating process failed before having installed a newer version of 
pip (it says “command not found”). I would stick to learning how to install 
stuff using pip (with which you can install many modules for Python, not only 
abjad). If you’re using Ubuntu, reinstalling pip is a matter of:

sudo apt update
sudo apt install python3-pip

Hello,

I’m looking for a “bracket” version of “\parenthesize” function to

Is there an easy way to create “\bracketize” function?

It's not ideal since the X-extent is hardcoded, but as a starting point:

bracketify =

  \tweak ParenthesesItem.text \markup \general-align #Y #CENTER {

Dear LilyPond community,


please consider this MWE:

Why doesn't the `VoiceFollower` grob obey the `minimum-length`

missing?

Hi,
yes the code was pretty old, about 2007.

So it is good to have updated this topic in the forum.
Thank you to you and everybody!

unofortunately I use Lilypond only once in a while, so I don’t use it enough to 
develop a deep knowledge as I would like.
first one who writes a book/tutorial on Lilypond… kudos!

 best to everybody

We are pleased to announce that Lilypond 2.21.80 has now been released and is 
available to download and install.  This is the first release candidate for the 
next stable version: 2.22.0, so we would be grateful if as many users as

Re: Lilypond and Python

[Martín Rincón Botero]

Hi Stefan. I remember having to make my version of Python 3 (3.6 I think) the 
system default (yours is 2.7) for abjad to work. I also remember having to 
install some things as root for it to work (you have a “Permission Denied” 
somewhere...). I read somewhere it’s not recommendable to use root with pip, 
but it worked with no discernible side effects.

Cheers,
Martín.

Re: The Guide to getting Point and Click going with Gvim under Ubuntu 18

[Martín Rincón Botero]

Thank you very much, Andrew, for this guide! It works! My pdf viewer is
Foxit Reader so after installing the gnome-open program and checking it
works, I didn't have to follow any other steps. I wish this guide can be
merged with the current guide in the Usage Manual. Just one small
suggestion to make this guide even more idiot-proof (at least for the steps
I did) would be to make this step a bit more verbose: "Create the file
'lilypond-invoke-editor.desktop' *f. ex. in your home folder*". The next
command assumes that you created the file via terminal and you moved to
that location with the terminal. In the case that you created that file
using GEdit (like I did) and followed the instructions in the Usage Manual
(where it mentions /tmp as folder), the next command won't really work
unless you're already there in the terminal (where I wasn't, since a
terminal opens by default with the home directory). This might be obvious
for people who do everything via terminal, but not for people who prefer
using graphical applications like GEdit. Is it maybe possible to create a
script that automates all this? Perhaps the Gvim and Evince parts can be
left out of it, but I have the feeling that what I just had to do can be
made into a script. I already can do some scripting in Python, but such a
script would need the user to have Python installed. So a Bash script from
someone acquainted with Bash would be very welcome.

Atom works very well even with large files, however there's a small lag
with point & click (even with small files). Since Frescobaldi doesn't have
this Point & Click problem even with large files, I assume this small lag
has more to do with the fact that there are two applications involved (Atom
and Foxit) rather than one (Frescobaldi). Am I right? This Point & Click
penalty is something that I'm willing to trade for the moment: it's less
than Frescobaldi hanging while trying to move the cursor, let alone for
trying to edit a large file. I hope this performance issue can be fixed in
Frescobaldi eventually (although Atom has other advantages like Column
Selection...).

Cheers,
Martín.

\bracketize?

[田村淳]

Hello,

I’m looking for a “bracket” version of “\parenthesize” function to enclose an 
articulation or ornamentation mark within a pair of square brackets. I’d like 
to use parenthesis and brackets to indicate two different types of editorial 
additions. I achieved the same for dynamics marks by slightly modifying the LSR 
code “Creating "real" parenthesized dynamics”
http://lsr.di.unimi.it/LSR/Item?id=382 
http://lsr.di.unimi.it/LSR/Snippet?id=382 

Is there an easy way to create “\bracketize” function?

Thanks in advance and best regards.

Re: Point & Click with Atom

[Martín Rincón Botero]

Thank you all for your helpful answers!

@Federico: I hope, you don’t take my criticism personally! I see Andrew has 
written upon what you wrote. That’s great! I’ll have to check how I installed 
Atom. If it’s in Ubuntu’s software center, I probably installed it from there 
(so it’s a snap, I suppose). Does it make any difference in the steps? And yes, 
Lilypond 2.20.

@Andrew: I’ll try your Ubuntu guide later. Thank you! I’m using Ubuntu 18.04., 
so your instructions should work.

Best regards,
Martín.

AIUI, the problem is made worse by the fact that - if you log in at the
gui - the shell doesn't get invoked AT ALL until it's needed to run the
command, at which point it's too late.

Catch 22 - the shell gets run after the command is called, but the
command needs the shell running first so the command-line knows where to
find the command!

I am not sure "character" and "column" is an accurate description.  From
what I seem to remember (but I'd have to look it up), the numbers are a
byte offset and a UTF-8 character position.  The former may be 0-based.
I don't think the latter takes anything like wide characters or tabs or
combining characters into account.

Hi Massimiliano,

the code you provided is _very_ old. I modified it a bit in order to 
work with both possible stem directions and respect rests. Also, there 
was a hard-coded offset for the cross that can more succinctly be 
replaced by a \center-align.


I also lenghened the stems a bit. Note that this does not work together 
with beams - I suspect it's got to do with unpure-pure-containers, which 
I don't understand :-).

   (length (ly:grob-property grob 'length))
   (actual-stem (ly:stem::print grob)))
   (if (ly:stencil? actual-stem) ; do not add anything if we don't 
have a stem (e.g. rests)

   (ly:stencil-combine-at-edge actual-stem
   1
   dir
   (ly:text-interface::print grob)
   (+ (* length -0.5) 0.75)) ; 0.75

I showed both \undo\sp and \once\sp in my example.

There exist 'wide characters', for example CJKV ideographs, which use
two columns per character on the terminal.
