Bug ID: 47703
Summary: MIDI generation on Windows fails with "No MIDI file
generated despite being requested"; Support
"-dmidi-extension=midi"
Product: MediaWiki extensions
Version: unspecified
Hardware: All
OS: Windows XP
Status: UNCONFIRMED
Severity: normal
Priority: Unprioritized
Component: Score
Assignee: wikibugs-l@lists.wikimedia.org
Reporter: gnosy...@gmail.com
CC: jger...@wikimedia.org
Classification: Unclassified
Mobile Platform: ---
-------------------
Reproductions steps
-------------------
* Install the Score extension on a Windows machine (I was able to reproduce on
Windows XP and Windows 7)
* Create a page with the following wikitext:
<score midi="1">\relative c' { d }</score>
* Click "Show Preview". The following error appears:
No MIDI file generated despite being requested. If you are working in raw
LilyPond mode, make sure to provide a proper \midi block.
-----
Cause
-----
* Score.body.php uses ".midi" throughout the file as the extension for MIDI
files
* However, on Windows, Lilypond treats ".mid" as the default extension for MIDI
files. See the following Lilypond page
(http://lilypond.org/doc/v2.15/Documentation/notation/creating-midi-files):
Due to some limitations on Windows, the default extension for MIDI files on
Windows is .mid.
--------------
Recommendation
--------------
* Add the "-dmidi-extension=midi" command line arg as per
http://www.lilypond.org/doc/v2.17/Documentation/usage/command_002dline-usage
Specifically:
midi-extension "midi" Set the default file extension for MIDI output file
to given string.
The recommended area of change would be here:
$cmd = wfEscapeShellArg( $wgScoreLilyPond )
. ' ' . wfEscapeShellArg( '-dsafe=#t' )
. ' -dmidi-extension=midi'
. ' -dbackend=ps --png --header=texidoc '
. wfEscapeShellArg( $factoryLy )
. ' 2>&1';
The above change allows me to generate MIDI files on my Windows XP box.
I've also tested the "-dmidi-extension=midi" command-line argument on Windows
XP, Windows 7, and Linux Mint Nadia. In each case, the output MIDI file has an
extension of ".midi" (i.e.: manually specifying "midi" on Linux seems to be
benign)
