-------------------------------------------------- translate ABC music notation to PostScript or SVG --------------------------------------------------
‘‘abcm2ps‘‘ [global_options] ABC_file [file_options] ...
‘‘abcm2ps‘‘ translates tunes written in the ABC music notation format to customary sheet music scores in PostScript or SVG. It is based on ‘‘abc2ps‘‘ 1.2.5 and was developed mainly to print Baroque organ scores that have independent voices played on multiple keyboards and a pedal-board. The program has since been extended to support various other notation conventions in use for sheet music.
Options given immediately after the command name apply to the run as a whole; options given after an ABC file name apply to that file.
Formatting parameters can also be set in "format files" and in the ABC files themselves.
The list of the command line options may be known running::
The options may be grouped when they have no argument, but the last one (ex: ‘‘-lnGI20‘‘).
The options may be disabled when starting with ’+’ or ending with ’-’ (ex: ‘‘+MT1‘‘ is the same as ‘‘-MT1-‘‘).
The general output format is the last found in the command line. It may be:
-E for Encapsulated PostScript, one file per tune
-g for SVG, one file per tune
-v for SVG, one file per page
-X for XHTML+SVG
-z for (X)HTML+SVG with (X)HTML+ABC input
(see below for more information)
List of the options -------------------
Read the abc file from stdin.
Set the <format> parameter to <value>.
This has the same effect as a format parameter
directly in the source file.
Maximal horizontal compression when staff breaks are
chosen automatically. Must be a float between 0 and 1.
This correspond to the ‘‘%%maxshrink‘‘
formatting parameter (default: 0.65).
This option inserts reference elements in the PostScript
or SVG output.
-B <int>, +B
Try to typeset <int> bars on each staff line.
This corresponds to the ‘‘%%barsperstaff‘‘ formatting parameter.
Start measure numbering at <int>.
This corresponds to the ‘‘%%measurefirst‘‘ formatting parameter.
The continuation symbol is implicitly appended to each
music line. This amounts to automatic line breaking.
This corresponds to the ‘‘%%continueall‘‘ formatting parameter.
Search the format files in the directory <dir>.
Set the vertical interstaff space to <unit>.
This corresponds to the ‘‘%%staffsep‘‘ formatting parameter
Produce EPS output instead of simple PS.
In this mode, each tune goes to a different file which
name is "<name>nnn.eps" or "<title>.eps" (see option ’-O’)
- ’nnn’ is a sequence number incremented at each tune
Output to stdout is forbidden.
EPS files are normally embedded into Postscript documents,
but they may be a way to generate graphical images. For
example, using GhostScript::
abcm2ps voices -Ee7
gs -sDEVICE=pngmono -r80 -g590x174 -dBATCH -dNOPAUSE -sOutputFile=quitolis.png Out001.eps
e values for -g are the values of the bounding box in
the .eps, multiplied by (80 / 72), where 80 is the value
for -r, and 72 is the default resolution)
-e [ <tune index list> ] [ <regular expression> ]
Select which tunes from an ABC file to print.
<tune index list> is either a comma-separated list of tune
numbers (as per the ‘‘X:‘‘ header), or a regular expression
which will be matched against the tune headers as a whole.
The ‘‘-e‘‘ option must occur after an ABC file
name and applies to that file.
Ranges of tune numbers may be specified like ‘‘<t1>-<t2>‘‘;
<t2> may be omitted which means
"all remaining tunes until the end of file". Note that
filtering may cause problems, e.g., with global (non-tune)
definitions in the ABC file.
This corresponds to the ‘‘%%select‘‘ formatting parameter.
-F <file>, +F
Read the format (or PostScript) file <file>.
When omitted, the default type of a format file is ’.fmt’.
In the form ’+F’, the default format file (’default.fmt’) is not
Enable flat beams (useful for bagpipe tunes).
This corresponds to the ‘‘%%flatbeams‘‘ formatting parameter.
Omit slurs on grace notes.
This corresponds to the ‘‘%%graceslurs‘‘ formatting parameter.
Produce SVG output instead of EPS.
In this mode each tune goes to a different file which name
is ’Outnnn.svg’ (see option ’-O’).
If the output is stdout (option ’-O-’), all the SVG images
are output without XML header.
Display the current format values.
Quick help, equivalent to "abcm2ps" without any arguments.
This also shows the default settings for some parameters.
Indent the first line of the tune by <unit> (default: 0).
This corresponds to the ‘‘%%indent‘‘ formatting parameter.
Insert a red cercle around the errors in the PostScript output.
-j <int>[b], +j
Output a measure number every <int> measures.
If <int> is 0, the measure number appears at the left of each staff.
The trailing ‘‘b‘‘ causes a box to be drawn
around each measure number (default: no measure numbering).
This corresponds to the ‘‘%%measurenb‘‘ formatting parameter.
Set the size of the PostScript output buffer in Kibytes.
Setting this value to a higher value permits the
generation of big tunes with -E or -g. The default value is 64.
Generate landscape output.
This corresponds to the ‘‘%%landscape‘‘ formatting parameter.
See the ‘‘%%writefields w‘‘ formatting parameter.
Set the left margin to <unit> (default: 1.8cm).
This corresponds to the ‘‘%%leftmargin‘‘ formatting parameter.
-N <int>, +N
Number the pages.
<int> indicates the mode:
no page numbers
at top left
at top right
at top left on even pages, top right on odd pages
at top right on even pages, top left on odd pages
For compatibility with previous versions, ’+N’ is the same as
’-N0’, and ’-N’ is the same as ’-N2’.
If a header is defined ("%%header"), this option is ignored.
Include notes and history from ABC tune ‘‘N:‘‘ fields.
See the ‘‘%%writehistory N‘‘ formatting parameter.
-O [ <directory> ] [ <name> ], +O
Define the output file directory and/or name.
The directory must end with the directory separator
(’/’ for unix/windows, ’\’ for mac).
By default, the output file goes to the current directory
with the name:
’Out.ps’ for PS,
’Outnnn.eps’ for EPS (see option ’-E’),
’Outnnn.svg’ for SVG (see options ’-g’ and ’-v’) or
’Out.xhtml’ for XHTML+SVG (see options ’-X’ and ’-z’).
’nnn’ is a sequence number.
When <name> is present, it is the name of the file, or it
replaces "Out" in the file name.
If <name> is ’=’, it is replaced by the name of the ABC
source file (not for ’-z’).
If <name> is ’-’, the result is output to stdout (not for EPS).
’+O’ resets the output file directory and name to their defaults.
When present, format output for bagpipe regardless of key.
When present, only the errors are shown.
Set the page scale factor to <float>. Note that the header
and footer are not scaled (default: 0.75).
This corresponds to the ‘‘%%scale‘‘ formatting parameter.
When present, file inclusion (%%format and %%EPS) and PostScript
injection (%%beginps and %%postscript) are disabled.
-T <int> [ <voice> ], +T [ <int> [<voice> ] ]
Activate or deactivate tablature drawing.
- <int> is the tablature number as defined in ‘‘%%tablature‘‘.
There may be only 8 different tablatures.
- <voice> is the voice name, full name or subname as found in V:.
When absent, apply to all voices.
Up to 4 such commands may be defined.
Ex: ’-T1flute +T2’
Show the version number.
Produce SVG output instead of simple PS.
In this mode each page goes to a different file which name
is ’Outnnn.svg’ (see option ’-O’).
Adjust the right margin such that the staff width
is <unit> (default: none).
This corresponds to the ‘‘%%staffwidth‘‘ formatting parameter.
Produce XML+SVG output instead of simple PS.
The default file name is ’Out.xhtml’ (see option ’-O’).
Include the ‘‘X:‘‘ tune number in the title.
This corresponds to the ‘‘%%writefields‘‘ formatting parameter.
Produce SVG images from ABC embedded in markup language files
The source file is copied to the output file and the ABC sequences
are converted to SVG images.
The ABC sequences start by either ‘‘%abc..‘‘ or ‘‘X:..‘‘
and stop on the first markup tag (‘‘<..‘‘).
The generation creates one image per block, i.e. a music line
or a text block. For a same rendering as the other SVG generation
(-g, -v or -X), don’t forget to set the line space to null, for
example enclosing the ABC sequences by::
<div style="line-height:0"> .. </div>
There can be only one output file.
Note that the default output file is ’Out.xhtml’, so, don’t
forget to change the file type if you generate HTML (.html)
or XML (.xml) files.
See "sample8.html" for a source example.
Split tunes across page breaks if necessary.
This corresponds to the ‘‘%%splittune‘‘ formatting parameter.
Output one tune per page.
This corresponds to the ‘‘%%oneperpage‘‘ formatting parameter.
ADDITIONAL FEATURES ===================
Clefs can be given in ‘‘K:‘‘ and ‘‘V:‘‘ headers.
The full syntax is::
"clef=" can be omitted when the <type> is a clef name.
<type> denotes the clef type. It may be:
- A note pitch (‘‘G‘‘, ‘‘C‘‘, or ‘‘F‘‘)
The pitch indicates which clef is meant:
‘‘G‘‘ is the treble clef,
‘‘C‘‘ the alto clef and
‘‘F‘‘ the bass clef.
It also gives the name of the note that appears
on the clef’s line.
- A clef name
The available clef names are
‘‘treble‘‘ (clef gives the pitch for ‘‘G‘‘),
‘‘alto‘‘ or ‘‘tenor‘‘ (‘‘C‘‘), and
- ‘‘perc‘‘ or ‘‘P‘‘
In percussion mode, accidentals change the glyphs used for
note heads. By default, sharp notes are drawn as "x" and
flat notes as circled "x".
This may be changed by redefining the PostScript functions
‘‘pshhd‘‘ and ‘‘pflhd‘‘.
No clef will be displayed.
The <line> gives the number of
the line within the staff that the base clef will be written
on. The default values are 2 for the treble clef, 3 for the
alto clef, and 4 for the tenor and bass clefs.
The "+8" and "-8"
options draw an 8 above or below the staff, respectively.
When no clef is specified, clef changes
and "treble" will be inserted
Multiple voices may be defined within the header or the
V:<name> <definition> ...
where <name> is a word consisting of letters and digits only
(like "violin1"). In the tune body, the
following notes refer to this voice until
another "V:" is encountered.
A <definition> can be one of:
* "name="<name> or "nm="<name>
The <name> will be
displayed at the beginning of the first staff. It can
contain "\n" sequences
which will force line breaks. If it contains
whitespace it must be double-quoted.
* "subname="<name> or "snm="<name>
The <name> will be displayed at the beginning of all staves
except for the first. It can
contain "\n" sequences
which will force line breaks. If it contains
whitespace it must be double-quoted.
The voice goes on the same staff as the previous voice.
* "up" or "down"
Forces the direction of the stems for the voice.
* "dyn=up" or "dyn=down" or "dyn=auto"
Forces positioning of dynamic marks (above or
below the staff) or reverts to automatic positioning
* "gstem=up" or "gstem=down" or "gstem=auto"
Forces the direction of the stems of grace
notes (always up or always down) or reverts to
automatic positioning (the default).
Reverts to automatic positioning of note stems
(up or down) (the default).
* "lyrics=up" or "lyrics=down" or "lyrics=auto"
Places lyrics above or below the staff or
reverts to automatic positioning (the default)
* "gchord=up" or "gchord=down"
Places guitar chords above (the default) or below the staff.
Sets the number of lines on the staff in question. (default: 5)
Sets the scale of the associated staff up to 3. (default: 1)
All other definitions are ignored.
Definition of the staff system
By default, each voice goes on its own
staff. The ‘‘%%staves <definition>‘‘
pseudo-comment can be used to control staff
assignment. The <definition>
consists of voice names (from ‘‘V:‘‘) and pairs of
parentheses, braces or brackets.
- When a voice name is not within a pair of
special characters, it goes on a separate staff.
- For voice names enclosed in brackets, a bracket
is displayed at the beginning of each line that joins
the staves of the voices in question.
- For voice names enclosed in braces, all the
voices go on two staves (keyboard score). There can be
at most four voices between a single pair of braces.
- For voice names enclosed in parentheses, all the
voices appear on a single staff.
The ‘‘|‘‘ character prevents measure bars from
being drawn between two staves.
If ‘‘%%staves‘‘ occurs in a tune, all the
voices not mentioned will not be output at all.
The ‘‘%%score‘‘ directive occurs in the ABC
draft 2.0 standard and is similar to
the ‘‘%%staves‘‘ specification described
above. The rules are:
- Voice names within parentheses form a "voice
group" and go on a single staff. A voice name that is
not within parentheses forms its own voice group and
goes on a staff by itself.
- Voice groups within braces form a "voice block"
and are preceded by a big brace in the output. This is
especially useful for keyboard music.
- Voice groups or voice blocks within brackets
form a "voice block" and will be preceded by a big
bracket in the output.
- If a ‘‘|‘‘ character occurs between two
voice groups or voice blocks, the bar lines in all of
the associated staves will be continuous.
- A single voice surrounded by two voice groups
can be preceded by an asterisk to make it into a
"floating" voice. This means that, for each note of the
voice, a separate decision is made whether it is printed
on the preceding or the following voice group’s staff.
- Voices that appear in the tune body but not in
the ‘‘%%score‘‘ directive will not be output at
all. If there is no ‘‘%%score‘‘ directive, each
voice will be output on its own staff.
- A ‘‘%%score‘‘ directive inside a tune
resets the mechanism so voices can be removed or added.
You can add notes to a staff without introducing a
complete extra voice by using the ampersand
(‘‘&‘‘). A single measure can be split into two voices like::
The ‘‘(&...&...&)‘‘ construction allows splitting multiple
|!f!(&GG<G|GG F=E| E2 E(_D/E)|_D D C D |C4- |C
&DC<C|CC_D C|=B,2_B,B, |_A,A,(G,/A,/)B,|F,4-|F,&)zzD=E|
A double ampersand (‘‘&&‘‘) will allow
overlaying more than two lines of music but this feature has
not yet been implemented.
Aligned lyrics under a staff are written as a
‘‘w:‘‘ line directly below the staff line. For example::
w:Three blind mice, three blind mice
Each word in the ‘‘w:‘‘ line (delimited by
blanks) is associated with one note, in sequence. The
following special symbols modify this behaviour:
Skips one note.
Splits a word into two syllables which are
associated with two adjacent notes. A "-" is drawn
Advances to the next bar line.
Is output as a space, but unites two words so
they appear under a single note.
Draws a thin underscore from the previous note
to the next.
To include more than one line of lyrics, use
multiple ‘‘w:‘‘ lines. To include hyphens without
splitting a word over multiple notes,
If a word starts with a digit, this is interpreted as a
stanza number and outdented a bit to the left.
Slurs and ties
The direction of slurs and ties may be controlled using
the "(," / "(’" and "-," / "-’" constructions.
Microtone pitches are indicated by a fraction after an
accidental, as in ‘‘^3/4c‘‘. When omitted, the
numerator defaultes to 1 and the denominator to 2
(so ‘‘^/c‘‘ is the same as ‘‘^1/2c‘‘). The
numerator and denominator values may not exceed 256. There
is built-in support for quarter-tone accidentals (1/2 and
3/2 sharps and flats); for other values, rendering functions
must be defined using ‘‘%%postscript‘‘.
EPS files may be included inside tunes using the
pseudo-comment ‘‘%%EPS <file>‘‘.
