Since version 2006-12-09 a file icon for midi files was added. If you want to allow midi files to be uploaded by the media manager and want them to be automatically recognized by DokuWiki, you should take the steps described here (using my mid.png or any other) and comment out the last lines of
You can do the same with a possible abc icon …
Please read the README that comes with the zip file!
The plugin stores all needed media files automatically in the DokuWiki media directory in a subnamespace (configurable through
mediaNS, default: “plugin_abc”). If you do not want them to be displayed and made accessible through the media popup, you can alter
./inc/search.php. In the first function
search() right after this
if(preg_match('/^[\._]/',$file)) continue; //skip hidden files and upper dirs
just add the following line:
if (substr($file,0,10)=='plugin_abc') continue; //skip plugin_abc dir
or substitute “plugin_abc” with your configured “mediaNS” accordingly.
<abc> X:42 T:Test M:4/4 K:C "C" C2 D2 E2 G2 |"C" c8 |] w:This is just a test </abc>
This code will lead to one of three possible outputs (set by
Since version 2005-11-20 it is possible to let the plugin transpose for you by an extra parameter. This parameter has to be a number between -23 and 23, which is the amount of semitones the tune will be transposed up (if positive) or down (if negative).
Since version 2006-02-21 it is possible to let the plugin transpose for you by extra parameters (separated by spaces; only 7 different values allowed). These parameters have to be numbers between -23 and 23, which is the amount of semitones that the tune will be transposed up (if positive) or down (if negative). E.g.
<abc 7 -3> X:42 T:Test M:4/4 K:C "C" C2 D2 E2 G2 |"C" c8 |] w:This is just a test </abc>

Hey!! Congratulations for your plugin!!! It would be great if you could extend it to be able to output tabs besides music sheets. Is it possible? – Jorge 2007-02-13 14:50
Thanks. Yes, outputting tabs is possible by using
abcm2ps. And the plugin has to be tweaked a little, as well (most probably, maybe not!? I haven't tested). But I have no time to do it in the too near future. — Anika Henke 2007-04-01 12:22
I found out that tabs can be done with
jaabc2ps, as well. With the new release (2007-06-03) of the abc plugin, you could change the
params4img config option to ”
-s 1 -T1CeBGDA,E, -o” or something similar. I don't know, if it will work right away, you might still be needing to tweak the plugin a bit more. But now it should be easier. — Anika Henke 2007-06-04 23:40
Hey Anika, I'm having an issue getting the plugin to run on my hosting service. They've given me access to all the binaries (abc2*, ps2pdf and convert) and I've setup the config file. Only issue I can think of is permissions. My page that uses the plugin is here. Got any tips for resolving this? Thanks. — Chris Freyer 2007-12-07 00:50
Hallo! 1. The
im_convert config option is not part of the plugin config, but of the main DokuWiki config. So it should be set there. 2. The message ”
(im_convert) is not executable” indicates that there is no path set in
$conf['im_convert']. Otherwise it would read ”
/path/to/convert (im_convert) is not executable”. — Anika Henke 2007-12-07 16:43
Here is reporting an ACL issue for the abc plugin on DokuWiki-2008-05-05 release version.
My wiki is set to be a closed wiki (@ALL default None), and set @ALL read to :stanley namespace and stanley page.
However, the abc tag on stanley:song page cannot show up PNG image file. You may see the URL - http://www.ichiayi.com/wiki/stanley/song
any idea? — Jonathan Tsai 2008/05/17 14:55
Hallo! Sorry, all abc media files are stored in the namespace “plugin_abc”. I did not want the “normal” media folders to be too cluttered. But unfortunately, this also means “normal” ACL rules will not apply. (In future releases I will make this namespace configurable!) You can either
- add an ACL ruleplugin_abc:* @ALL 1
- or change the following lines in
./lib/plugins/abc/syntax.php(in order to not store all files in “plugin_abc”, but in their correct corresponding namespace)://line 177: $abcdir = $savedir.'/media/plugin_abc'; //line 354: $abcMediaUrl=DOKU_BASE."lib/exe/fetch.php?cache=cache&media=plugin_abc:";
to//line 177: $abcdir = $savedir.'/media'; //line 354: $abcMediaUrl=DOKU_BASE."lib/exe/fetch.php?cache=cache&media=";
— Anika Henke 2008/05/18 11:54Thanks Anika,
After comparing the adding an ACL rule method and the other method to modify './lib/plugins/abc/syntax.php' code , I would like to choose the last one to solve the issue. Because it can let all abc files following my ACL rules setting. Thank you again for your kindly and rapidly reply.

Hmmm, tried to get the plugin working with jcabc2ps but that directly writes to stdout and I haven't got a clue how to fix this and either change the plugin to do something like jcabc2ps filename.abc > filename.ps or alter jcabc2ps to directly dump to .ps. (The reason I'd like to use jcabc2ps is the more clever way of altering bass notes and such… http://trillian.mit.edu/~jc/music/abc/doc/ABCtut_Clefs.html Anything anyone could fix? (I might try to fiddle around with it a bit myself, but I have very little knowledge of PHP…) — Harmen 2009/03/31 17:14
I'm not too sure what to put when setting ps2pdf. I've tried putting
c:\xxx\xxx\ghostscript\gs8.71\lib\ps2pdf14 and I get the error message that it's not an executable. There's no .exe files that I can see in the ghostscript folder. Midi & ps conversion works fine. Dokuwiki on local install. Any help appreciated.

I understood that I have to put the following in the plugin beginning to obtain a transposition:
<abc 7 -3>
Do I need to do something else to obtain a transposition? I copied your example in my page but it seems to not work. What did I missed?
I recive the folowing errors: abc2ps In tune
Error : 'staffwidth' too big

That is just a feedback from abcm2ps which you can ignore or even turn off with the
displayErrorlogconfig option. The messages will only be displayed the first time you save a page with ABC in it, after that they will disappear. — Anika Henke 2013/07/11 01:39
So, please tell me where exactly should I post this debugging code
var $_debug = 1?There is only one syntax.php in the plugin and there is only one “var $_debug”.
For test I made myself via notepad an ABC File with this content:
“C” C2 D2 E2 G2 |”C” c8 |]
w:This is just a test.
</abc>ABC files shouldn't have <abc></abc> in them. That's only meant for DokuWiki to know that the content can be rendered by the ABC plugin.Good to know.
1.This is my first manual testing steps:
Win server 2003. Run, cmd:
C:\Utile\abcm2ps>C:\Utile\abcm2ps\abcm2ps.exe test.abc -s 1 -w 600 -E -O test. 2>&1
abcm2ps-6.6.22 (November 28, 2012)
- In tune '':
Error : 'staffwidth' too big
Output written on test001.eps
2.C:\Utile\ImageMagick-6.8.6-Q8\convert.exe C:\Utile\abcm2ps\test001.eps -flatten test.png
convert: Postscript delegate failed `rrr.eps': No such file or directory @ error/ps.c/ReadPSImage/837.
convert: no images defined `rrr.png' @ error/convert.c/ConvertImageCommand/3106.You are probably missing the Ghostscript delegate library. Install it from here: http://www.imagemagick.org/script/binary-releases.php
Anika HenkeIt works! My advice is to open the imdisplay.exe inside ImageMagick folder and try to open manually test001.eps. If you see the image the converter is working. (to me it did not work before installing GhostScript application!)
Pay attention too to the apache error.log. It seems that for some reasons the path to im_converter (set in Configuration Manager DW) to not be recognized because of the space between C:\Program(space)files\path. For me it worked installing outside Program Files.Florin
