Описание (Description)
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. .PDFPIC is available, but does on yet work with
lilypond.
If no operands are given, or if file is '-', glilypond reads the
standard input stream. A double-dash argument ('--') causes all
subsequent arguments to be interpreted as file operands, even if
their names start with a dash.
Использование (Usage)
Together with .PSPIC, glilypond can work only for troff devices
without PDF and X devices.
I.e., the following groff devices work, -Tps, -Tdvi, -Thtml, and
-Txhtml.
I'm not sure about the lbp and lj4 devices.
Unfortunately, the groff option -Tpdf does not work.

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 temporary 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
deleted. With this option, all generated files either by
the lilypond 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
STDOUT. 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 argument, composed as a collection of option characters
following the single dash.
Such a collection can be terminated by an option character that
expects 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.

Integrated LilyPond code
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 .lilypond include may not be used in lilypond mode, i.e.
between .lilypond start and .lilypond end. These included ly-
files are also transformed into EPS files.
Generated files
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 options -p or --prefix.
All of the temporary files except the EPS files are deleted
finally. This can be changed by setting the command-line options
-k or --keep_files. 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
Mode pdf2eps
This mode is the actual default and can also be chosen by the
option --pdf2eps.
In this mode, the .ly files are transformed by the lilypond(1)
program into PDF files, using
lilypond --pdf --output=file-name
for each .ly file. The file-name must be provided without the
extension .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.pds
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
Mode ly2eps
In earlier time, this mode was the default. But now it does not
work any more, so accept the new default pdf2eps. For testing,
this mode can also be chosen by the glilypond 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
transformed 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
collection of the corresponding EPS page files. This is done by
groff commands
.PSPIC file-name-digit.eps
Generated [22mgroff[24m [1moutput
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
2) stored into a file by given the option -o | --output
file_name
