27 glilypond transforms sheet music written in the lilypond language into
28 the groff(7) language using the .PSPIC request, such that groff(1) can
29 transform it into a format that can be displayed directly. .PDFPIC is
30 available, but does on yet work with lilypond.
31
32 Files in groff language and standard input can be provided as argu‐
33 ments.
34
36 Together with .PSPIC, glilypond can work only for troff devices without
37 PDF and X devices.
38
39 I.e., the following groff devices work, -Tps, -Tdvi, -Thtml, and -Tx‐
40 html.
41
42 I'm not sure about the ldp and lj4 devices.
43
44 In groffer, it is easier to use the following device options, either
45 --ps, --div, --html, or --xhtml.
46
47 Unfortunately, the groff option -Tpdf does not work and the groffer de‐
48 fault PDF works neither.
49
50 But groffer has an additional pdf mode, not available in groff. It is
51 based on the ps mode in groff and is called through groffer --pdf2
52 roff-file-with-lilypond.

65 Options for building EPS Files
66 [--ly2eps]
67 Here the lilypond program creates eps files directly. This is
68 the default.
69
70 [--pdf2eps]
71 The program glilypond generates a PDF file using lilypond. Then
72 the eps file is generated by pdf2ps and ps2epsR.
73
74 Directories and Files
75 -e|--eps_dir directory_name
76 Normally all EPS files are sent to the temporary directory.
77 With this option, you can generate your own directory, in which
78 all useful EPS files are send. So at last, the temporary direc‐
79 tory can be removed.
80
81 -p|--prefix begin_of_name
82 Normally all temporary files get names that start with the ly...
83 prefix. With this option, you can freely change this prefix.
84
85 -k|--keep_all
86 Normally all temporary files without the eps files are deleted.
87 With this option, all generated files either by the lilypond
88 program or other format transposers are kept.
89
90 -t|--temp_dir dir
91 With this option, you call a directory that is the base for the
92 temporary directory. This directory name is used as is without
93 any extensions. If this directory does not exist it is be cre‐
94 ated. The temporary directory is created by Perl's security op‐
95 erations directly under this directory. In this temporary di‐
96 rectory, the temporary files are stored.
97
98 Output
99 -o|--output file_name
100 Normally all groff output of this program is sent to STDOUT.
101 With this option, that can be changed, such that the output is
102 stored into a file named in the option argument file_name.
103
104 -v|-V|--verbose
105 A lot more of information is sent to STDERR.
106
107 Short Option Collections
108 The argument handling of options
109
110 Short options are arguments that start with a single dash -. Such an
111 argument can consist of arbitrary many options without option argument,
112 composed as a collection of option characters following the single
113 dash.
114
115 Such a collection can be terminated by an option character that expects
116 an option argument. If this option character is not the last character
117 of the argument, the following final part of the argument is the option
118 argument. If it is the last character of the argument, the next argu‐
119 ment is taken as the option argument.
120
121 This is the standard for POSIX and GNU option management.
122
123 For example,
124
125 -kVe some_dir
126 is a collection of the short options -k and -V without option
127 argument, followed by the short option -e with option argument
128 that is the following part of the argument some_dir. So this
129 argument could also be written as several arguments -k -V -e
130 some_dir.
131
132 Handling of Long Options
133 Arguments that start with a double dash -- are so-called long options R
134 . Each double dash argument can only have a single long option.
135
136 Long options have or have not an option argument. An option argument
137 can be the next argument or can be appended with an equal sign = to the
138 same argument as the long option.
139
140 --help is a long option without an option argument.
141
142 --eps_dir some_dir
143 --eps_dir=some_dir
144 is the long option --eps_dir with the option argument some_dir.
145
146 Moreover the program allows abbreviations of long options, as much as
147 possible.
148
149 The long option --keep_all can be abbreviated from --keep_al up to --k
150 because the program does not have another long option whose name starts
151 with the character k.
152
153 On the other hand, the option --version cannot be abbreviated further
154 than --vers because there is also the long option --verbose that can be
155 abbreviated up to --verb.
156
157 An option argument can also be appended to an abbreviation. So is
158 --e=some_dir the same as --eps_dir some_dir.
159
160 Moreover the program allows an arbitrary usage of upper and lower case
161 in the option name. This is Perl style.
162
163 For example, the long option --keep_all can as well be written as
164 --Keep_All or even as an abbreviation like --KeE.
165
167 An argument that is not an option or an option argument is called a
168 filespec argument.
169
170 Without any filespec argument, standard input is read.
171
172 Each filespec argument must either be the name of a readable file or a
173 dash - for standard input. Each input must be written in the roff or
174 groff language and can include lilypond parts.
175
176 Normally arguments starting with a dash - are interpreted as an option.
177 But if you use an argument that consists only of a doubled dash -- R ,
178 all following arguments are taken as filespec argument, even if such an
179 argument starts with a dash. This is handled according to the GNU
180 standard.
181
183 Integrated Lilypond Codes
184 A lilypond part within a structure written in the groff language is the
185 whole part between the marks
186 .lilypond start
187 and
188 .lilypond end
189
190 A groff input can have several of these lilypond parts.
191
192 When processing such a lilypond part between .lilypond start and .lily‐
193 pond end we say that the glilypond program is in lilypond mode.
194
195 These lilypond parts are sent into temporary lilypond files with the
196 file name extension .ly. These files are transformed later on into EPS
197 files.
198
199 Inclusion of ly-Files
200 An additional command line for file inclusion of lilypond files is
201 given by
202 .lilypond include file_name
203 in groff input. For each such include command, one file of lilypond
204 code can be included into the groff code. Arbitrarily many of these
205 commands can be included in the groff input.
206
207 These include commands can only be used outside the lilypond parts.
208 Within the lilypond mode, this inclusion is not possible. So .lilypond
209 include may not be used in lilypond mode, i.e. between .lilypond start
210 and .lilypond end. These included ly-files are also transformed into
211 EPS files.
212
214 By the transformation process of lilypond parts into EPS files, there
215 are many files generated. By default, these files are regarded as tem‐
216 porary files and as such stored in a temporary directory.
217
218 This process can be changed by command-line options.
219
220 Command Line Options for Directories
221 The temporary directory for this program is either created automati‐
222 cally or can be named by the option -t|--temp_dir dir.
223
224 Moreover, the EPS files that are later on referred by .PSPIC command in
225 the final groff output can be stored in a different directory that can
226 be set by the command-line option -e|--eps_dir directory_name. With
227 this option, the temporary directory can be removed completely at the
228 end of the program.
229
230 The beginning of the names of the temporary files can be set by the
231 command-line option [-p |] begin_of_name.
232
233 All of the temporary files except the EPS files are deleted finally.
234 This can be changed by setting the command-line option [-k |] With
235 this, all temporary files and directories are kept, not deleted.
236
237 These EPS files are stored in a temporary or EPS directory. But they
238 cannot be deleted by the transformation process because they are needed
239 for the display which can take a long time.
240
242 Mode pdf2eps
243 This mode is the actual default and can also be chosen by the option
244 --pdf2eps.
245
246 In this mode, the .ly files are transformed by the lilypond(1) program
247 into PDF files, using
248 lilypond --pdf --output=file-name
249 for each .ly file. The file-name must be provided without the exten‐
250 sion .pdf. By this process, a file file-name.pdf is generated.
251
252 The next step is to transform these PDF files into a PS file. This is
253 done by the pdf2ps(1) program using
254 $ pdf2ps file-name .pdf file-name .ps
255 The next step creates an EPS file from the PS file. This is done by
256 the ps2eps(1) program using
257 $ ps2eps file-name.ps
258
259 By that, a file file-name.eps is created for each lilypond part in the
260 groff file or standard input.
261
262 The last step to be done is replacing all lilypond parts by the groff
263 command
264 .PSPIC file-name.eps
265
266 Mode ly2eps
267 In earlier time, this mode was the default. But now it does not work
268 any more, so accept the new default pdf2eps. For testing, this mode
269 can also be chosen by the glilypond option --ly2eps.
270
271 In this mode, the .ly files are transformed by the lilypond program
272 into many files of different formats, including eps files, using
273 $ lilypond --ps -dbackend=eps -dgs-load-fonts --output=file-name
274 for each .ly file. The output file-name must be provided without an
275 extension, its directory is temporary.
276
277 There are many EPS files created. One having the complete transformed
278 ly file, named file-name.eps.
279
280 Moreover there are EPS files for each page, named file-name-digit.eps.
281
282 The last step to be done is replacing all lilypond parts by the collec‐
283 tion of the corresponding EPS page files. This is done by groff com‐
284 mands
285 .PSPIC file-name-digit.eps
286
288 The new groff(7) structure generated by glilypond is either
289
290 1) sent to standard output and can there be saved into a file or
291 piped into groff(1) or groffer(1) or
292
293 2) stored into a file by given the option -o | --output file_name
