乐谱扩展允许你像PNG这样使用LilyPond渲染乐谱,并且可以将其转化为音频和MIDI文件。

用法
After setup, you can embed simple LilyPond notation into your wikitext inside a <score>...</score>
tag. For example:
<score>\relative c' { f d f a d f e d cis a cis e a g f e }</score>
产生:
You may also specify attributes to the score tags in the general form
<score attribute1="value1" attribute2="value2">…</score>.
例如:
<score sound="1">\relative c' { \set Staff.midiInstrument = "tenor sax" f d f a d f e d cis a cis e a g f e }</score>
产生:
The following attributes are available:
属性 | 允许的值 | 效果 |
---|---|---|
lang | ABC, lilypond (default) | 设置乐谱语言。例如,以ABC简谱表示一个乐谱,可以使用: <score lang="ABC">
X:1
M:C
L:1/4
K:C
C, D, E, F,|G, A, B, C|D E F G|A B c d|
e f g a|b c' d' e'|f' g' a' b'|]
</score>
|
midi | (已移除) This used to control whether the rendered score image linked to a MIDI file. | |
override_midi | Known file name, that is, if override_midi="name" is given, [[File:name]] does not yield a red link |
(已弃用) Instead you can add a [[File:superior midi filename.mid]] wikilink after the closing </score> tag.Uses the specified MIDI file instead of generating one with LilyPond. Use this attribute together with the midi attribute (see before) or the sound attribute (see later). This attribute is useful if you already have a MIDI file whose quality is superior to what would be generated by LilyPond. |
override_audio | Known file name, that is, if override_audio="name" is given, [[File:Name]] does not yield a red link |
(已弃用) Instead you can add a [[File:superior audio filename.oga]] wikilink after the closing </score> tag.Embeds the media specified by the file name in the HTML after the score image(s). This is an alternative to the sound attribute (see further). It can, for example, be useful if you have a suitable audio file of superior quality compared with the auto-generated audio file. Of course, you can still omit both attributes in this case and add the file manually to the page, if you prefer. |
override_ogg | (已弃用) Doubly-deprecated alias for override_audio. | |
raw | 0 (default), 1 | If set to 1, the score code is interpreted as a complete LilyPond file. Use this option if you want to create more complex scores. If the score language (lang attribute) is not set to lilypond, this attribute is ignored. By default (when raw=0), provided code is wrapped in a \score{...} block, along with default \layout{...} and \midi{...} blocks, if not already provided.
|
sound | 0 (default), 1 | If set to 1, an audio file will be generated for the score, provided you installed and configured 扩展:TimedMediaHandler . An audio player will be embedded in the HTML after the score image(s). |
vorbis | 0 (default), 1 | (已弃用) Alias for sound. |
The LilyPond language
Lyrics may be added like this:
<score>
\relative c'' { \time 4/4 \key c \major
c4 g8 g a4 g r b^> c^> r \bar "|." }
\addlyrics { Shave and a hair -- cut: two bits. }
</score>
For advanced users, the \set Staff.midiInstrument
command can be used to change the MIDI instrument for the sound.
Prerequisites
The following packages are recommended:
- LilyPond
- Ghostscript
- ImageMagick
- FluidSynth
- Firejail
This extension uses LilyPond to render score images, so you need a working LilyPond installation (Special:Version displays the LilyPond version). If you install LilyPond from a package, Ghostscript will also be installed, since LilyPond depends on Ghostscript. ImageMagick should be installed to trim the images, otherwise they will contain an excessive amount of whitespace.
For security reasons, it is highly recommended to install firejail to further restrict what LilyPond and Ghostscript can do if untrusted users are allowed to edit your wiki.
The extension is also capable of creating audio files from the MIDI files generated by LilyPond. If you want to make use of this functionality, you need to have 扩展:TimedMediaHandler installed.
FluidSynth is the preferred method to convert MIDI files to audio files, however TiMidity++ is also supported.
Security concerns
Score uses LilyPond in safe mode, however there are known unfixed safe mode escape vulnerabilities leading to arbitrary execution.
If you don't absolutely trust everyone who has editing privileges on your wiki, it is strongly recommended to set up containment of lilypond using Shellbox . See Shellbox#Server setup for details on how to set up the contained server, and below for configuring MediaWiki to use it. Also, ensure you're using a recent version of LilyPond (2.22.0+) or a distribution package (e.g. from Debian) that has security fixes. Keep safe mode enabled, even with containment as an extra layer of defense. Certain functionality will not work in safe mode, the fix for that is to modify LilyPond to allow that functionality in safe mode.
安裝
- See the extension's
README.md
for detailed installation instructions.
- 下载文件,并将解压后的
Score
文件夹移动到extensions/
目录中。
开发者和代码贡献人员应从Git安装扩展,输入:cd extensions/
git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/Score - 将下列代码放置在您的LocalSettings.php 的底部:
wfLoadExtension( 'Score' ); $wgScoreTrim = true; $wgImageMagickConvertCommand = '/usr/bin/convert'; $wgShellboxUrl = '... address to Shellbox ...'; $wgShellboxSecretKey = '... your secret key ...';
- Create a subdirectory named
lilypond
in your $wgUploadDirectory (usually the directory namedimages
in your MediaWiki directory). Make sure the directory is writable by your Web server. - 完成 – 在您的wiki上导航至Special:Version,以验证已成功安装扩展。
配置
Here are some of the extension's global configuration parameters.
$wgScoreLilyPond
Set $wgScoreLilyPond
to the path to your LilyPond executable (typically /usr/bin/lilypond
or /usr/local/bin/lilypond
).
$wgScoreTrim
The $wgScoreTrim
is a boolean which defaults to the value of $wgUseImageMagick
. If true
, the resulting score PNG images are trimmed with ImageMagick. If you don't want trimming, or don't want to install ImageMagick, set $wgScoreTrim
to false
.
$wgScoreAbc2Ly
Set $wgScoreAbc2Ly
to the path of your ABC to LilyPond converter executable (typically /usr/bin/abc2ly
or /usr/local/bin/abc2ly
).
$wgScoreFluidsynth
Set $wgScoreFluidsynth
to the path of your Fluidsynth executable (typically /usr/bin/fluidsynth
or /usr/local/bin/fluidsynth
).
$wgScoreSoundfont
Set $wgScoreSoundfont
to the path of your soundfont file (typically /usr/share/sounds/sf2/FluidR3_GM.sf2
or /usr/share/sounds/sf2/FluidR3_GS.sf2
).
$wgScoreLame
Set $wgScoreLame
to the path of your Lame executable (typically /usr/bin/lame
or /usr/local/bin/lame
). Required if the generated audio file should be a MP3.
Remarks
This extension runs various binaries in a Shellbox to provide some security. You may have to increase $wgMaxShellMemory if you get "out of memory" errors.
Finding scores
Pages containing <score>
tags are in the tracking category with message name 'score-use-category'.
Visit Special:TrackingCategories to find the localized title of this category on your wiki and show the pages in it, for example w:Category:Pages using the Score extension on the English Wikipedia.
