glilypond — integrate lilypond parts into groff
SYNOPSIS top
glilypond [ options] [-] [--] [ filespec ....]
DESCRIPTION top
glilypond transforms sheet music written in the lilypond language
into the groff(7) language using the .PSPIC request, such that
groff(1) can transform it into a format that can be displayed
directly.
Files in groff language and standard input can be provided as
arguments.
OPTION OVERVIEW top
Breaking Options
-?|-h|--help|--usage
Print help or usage information, then leave the program.
--version
Print version information.
-l|--license
Print license information.
Options for building EPS Files
[--ly2eps]
Here the lilypond program creates eps files directly. This is
the default.
[--pdf2eps]
The program glilypond generates a pdf file using lilypond.
Then the eps file is generated by pdf2ps and ps2epsR.
Directories and Files
-e|--eps_dir directory_name
Normally all EPS files are sent to the temporary directory.
With this option, you can generate your own directory, in
which all useful EPS files are send. So at last, the tempo‐
rary directory can be removed.
-p|--prefix begin_of_name
Normally all temporary files get names that start with the
ly.... prefix. With this option, you can freely change this
prefix.
-k|--keep_all
Normally all temporary files without the eps files are delet‐
ed. With this option, all generated files either by the lily‐
pond program or other format transposers are kept.
-t|--temp_dir dir
With this option, you call a directory that is the base for
the temporary directory. This directory name is used as is
without any extensions. If this directory does not exist it
is be created. The temporary directory is created by Perl's
security operations directly under this directory. In this
temporary directory, the temporary files are stored.
Output
-o|--output file_name
Normally all groff output of this program is sent to STDOUTR.
With this option, that can be changed, such that the output is
stored into a file named in the option argument file_name.
-v|-V|--verbose
A lot more of information is sent to STDERR.
Short Option Collections
The argument handling of options
Short options are arguments that start with a single dash -. Such an
argument can consist of arbitrary many options without option argu‐
ment, composed as a collection of option characters following the
single dash.
Such a collection can be terminated by an option character that ex‐
pects an option argument. If this option character is not the last
character of the argument, the following final part of the argument
is the option argument. If it is the last character of the argument,
the next argument is taken as the option argument.
This is the standard for POSIX and GNU option management.
For example,
-kVe some_dir
is a collection of the short options -k and -V without option
argument, followed by the short option -e with option argument
that is the following part of the argument some_dir. So this
argument could also be written as several arguments -k -V -e
some_dir.
Handling of Long Options
Arguments that start with a double dash -- are so-called long options
R . Each double dash argument can only have a single long option.
Long options have or have not an option argument. An option argument
can be the next argument or can be appended with an equal sign = to
the same argument as the long option.
--help is a long option without an option argument.
--eps_dir some_dir
--eps_dir=some_dir
is the long option --eps_dir with the option argument
some_dir.
Moreover the program allows abbreviations of long options, as much as
possible.
The long option --keep_all can be abbreviated from --keep_al up to
--k because the program does not have another long option whose name
starts with the character k.
On the other hand, the option --version cannot be abbreviated further
than --vers because there is also the long option --verbose that can
be abbreviated up to --verb.
An option argument can also be appended to an abbreviation. So is
--e=some_dir the same as --eps_dir some_dir.
Moreover the program allows an arbitrary usage of upper and lower
case in the option name. This is Perl style.
For example, the long option --keep_all can as well be written as
--Keep_All or even as an abbreviation like --KeE.
FILESPEC ARGUMENTS top
An argument that is not an option or an option argument is called a
filespec argument.
Without any filespec argument, standard input is read.
Each filespec argument must either be the name of a readable file or
a dash - for standard input. Each input must be written in the roff
or groff language and can include lilypond parts.
Normally arguments starting with a dash - are interpreted as an
option. But if you use an argument that consists only of a doubled
dash -- R , all following arguments are taken as filespec argument,
even if such an argument starts with a dash. This is handled
according to the GNU standard.
THE LILYPOND PARTS IN ROFF INPUT top
Integrated Lilypond Codes
A lilypond part within a structure written in the groff language is
the whole part between the marks
.lilypond start
and
.lilypond end
A groff input can have several of these lilypond parts.
When processing such a lilypond part between .lilypond start and
.lilypond end we say that the glilypond program is in lilypond mode.
These lilypond parts are sent into temporary lilypond files with the
file name extension .ly. These files are transformed later on into
EPS files.
Inclusion of ly-Files
An additional command line for file inclusion of lilypond files is
given by
.lilypond include file_name
in groff input. For each such include command, one file of lilypond
code can be included into the groff code. Arbitrarily many of these
commands can be included in the groff input.
These include commands can only be used outside the lilypond parts.
Within the lilypond mode, this inclusion is not possible. So .lily‐
pond include may not be used in lilypond mode, i.e. between .lilypond
start and .lilypond end. These included ly-files are also trans‐
formed into EPS files.
GENERATED FILES top
By the transformation process of lilypond parts into EPS files, there
are many files generated. By default, these files are regarded as
temporary files and as such stored in a temporary directory.
This process can be changed by command line options.
Command Line Options for Directories
The temporary directory for this program is either created
automatically or can be named by the option -t|--temp_dir dir.
Moreover, the EPS files that are later on referred by .PSPIC command
in the final groff output can be stored in a different directory that
can be set by the command line option -e|--eps_dir directory_name.
With this option, the temporary directory can be removed completely
at the end of the program.
The beginning of the names of the temporary files can be set by the
command line option [-p |] begin_of_name.
All of the temporary files except the EPS files are deleted finally.
This can be changed by setting the command line option [-k |] With
this, all temporary files and directories are kept, not deleted.
These EPS files are stored in a temporary or EPS directory. But they
cannot be deleted by the transformation process because they are
needed for the display which can take a long time.
TRANSFORMATION PROCESSES FOR GENERATING EPS FILES top
Mode ly2eps
This mode is the default. It can also be chosen by the option
--ly2eps.
In this mode, the .ly files are transformed by the lilypond program
into many files of different formats, including eps files, using
$ lilypond --ps -dbackend=eps -dgs-load-fonts --output=file-name
for each .ly file. The output file-name must be provided without an
extension, its directory is temporary.
There are many EPS files created. One having the complete trans‐
formed ly file, named file-name.eps.
Moreover there are EPS files for each page, named
file-name-digit.eps.
The last step to be done is replacing all lilypond parts by the col‐
lection of the corresponding EPS page files. This is done by groff
commands
.PSPIC file-name-digit.eps
Mode pdf2eps
This mode can be chosen by the option --pdf2eps.
In this mode, the .ly files are transformed by the lilypond(1) pro‐
gram into pdf files, using
lilypond --pdf --output=file-name
for each .ly file. The file-name must be provided without the exten‐
sion .pdf. By this process, a file file-name.pdf is generated.
The next step is to transform these PDF files into a PS file. This
is done by the pdf2ps(1) program using
$ pdf2ps file-name .pdf file-name .ps
The next step creates an EPS file from the PS file. This is done by
the ps2eps(1) program using
$ ps2eps file-name.ps
By that, a file file-name.eps is created for each lilypond part in
the groff file or standard input.
The last step to be done is replacing all lilypond parts by the groff
command
.PSPIC file-name.eps
THE GENERATED NEW ROFF STRUCTURE top
The new groff(7) structure generated by glilypond is either
1) sent to standard output and can there be saved into a file or
piped into groff(1) or groffer(1) or
2) stored into a file by given the option -o | --output
file_name
