DESCRIPTION

22       The  application  described by this document, dtplite, is the successor
23       to the extremely simple mpexpand. Influenced in  its  functionality  by
24       the  dtp doctools processor it is much more powerful than mpexpand, yet
25       still as easy to use; definitely easier than dtp  with  its  myriad  of
26       subcommands and options.
27
28       dtplite  is based upon the package doctools, like the other two proces‐
29       sors.
30
31   USE CASES
32       dtplite was written with the following three use cases in mind.
33
34       [1]    Validation of a single document, i.e. checking that it was writ‐
35              ten  in valid doctools format. This mode can also be used to get
36              a preliminary version of the formatted output for a single docu‐
37              ment, for display in a browser, nroff, etc., allowing proofread‐
38              ing of the formatting.
39
40       [2]    Generation of the formatted documentation for a single  package,
41              i.e.  all the manpages, plus a table of contents and an index of
42              keywords.
43
44       [3]    An extension of the previous mode of operation, a method for the
45              easy  generation of one documentation tree for several packages,
46              and especially of a unified table of contents and keyword index.
47
48       Beyond the above we also want to make use of the customization features
49       provided  by the HTML formatter. It is not the only format the applica‐
50       tion should be able to generate, but we anticipiate it to be  the  most
51       commonly  used, and it is one of the few which do provide customization
52       hooks.
53
54       We allow the caller to  specify  a  header  string,  footer  string,  a
55       stylesheet,  and  data  for a bar of navigation links at the top of the
56       generated document.  While all can be set as long as the formatting en‐
57       gine provides an appropriate engine parameter (See section OPTIONS) the
58       last two have internal processing which make them specific to HTML.
59
60   COMMAND LINE
61       dtplite -o output ?options? format inputfile
62              This is the form for use case [1]. The options will be explained
63              later, in section OPTIONS.
64
65              path output (in)
66                     This argument specifies where to write the generated doc‐
67                     ument. It can be the path to a file or directory,  or  -.
68                     The last value causes the application to write the gener‐
69                     ated documented to stdout.
70
71                     If the output does not exist then [file dirname  $output]
72                     has  to exist and must be a writable directory.  The gen‐
73                     erated document will be written to a file in that  direc‐
74                     tory,  and the name of that file will be derived from the
75                     inputfile, the format, and the value given to option -ext
76                     (if present).
77
78              (path|handle) format (in)
79                     This argument specifies the formatting engine to use when
80                     processing the input, and thus the format of  the  gener‐
81                     ated  document. See section FORMATS for the possibilities
82                     recognized by the application.
83
84              path inputfile (in)
85                     This argument specifies the path to the file to  process.
86                     It  has  to  exist, must be readable, and written in doc‐
87                     tools format.
88
89
90       dtplite validate inputfile
91              This is a simpler form for use case [1]. The  "validate"  format
92              generates no output at all, only syntax checks are performed. As
93              such the specification of an output file or other options is not
94              necessary and left out.
95
96       dtplite -o output ?options? format inputdirectory
97              This  is the form for use case [2]. It differs from the form for
98              use case [1] by having the input documents specified  through  a
99              directory  instead of a file. The other arguments are identical,
100              except for output, which now has to be the path to  an  existing
101              and writable directory.
102
103              The  input  documents  are all files in inputdirectory or any of
104              its subdirectories which were recognized  by  fileutil::fileType
105              as containing text in doctools format.
106
107       dtplite -merge -o output ?options? format inputdirectory
108              This  is  the  form for use case [3]. The only difference to the
109              form for use case [2] is the additional option -merge.
110
111              Each such call will merge the generated  documents  coming  from
112              processing  the  input  documents under inputdirectory or any of
113              its subdirectories to the files under output. In this manner  it
114              is possible to incrementally build the unified documentation for
115              any number of packages. Note that it is necessary to run through
116              all  the  packages  twice  to get fully correct cross-references
117              (for formats supporting them).
118
119   OPTIONS
120       This section describes all the options available to the user of the ap‐
121       plication,  with  the exception of the options -o and -merge. These two
122       were described already, in section COMMAND LINE.
123
124       -exclude string
125              This option specifies an exclude (glob) pattern. Any files iden‐
126              tified  as  manpages  to process which match the exclude pattern
127              are ignored. The option can be provided multiple times, each us‐
128              age adding an additional pattern to the list of exclusions.
129
130       -ext string
131              If the name of an output file has to be derived from the name of
132              an input file it will use the name of the format as  the  exten‐
133              sion  by  default.  This option here will override this however,
134              forcing it to use string as the file extension. This  option  is
135              ignored  if  the  name  of  the  output  file is fully specified
136              through option -o.
137
138              When used multiple times only the last definition is relevant.
139
140       -header file
141              This option can be used if and only if the selected format  pro‐
142              vides  an engine parameter named "header". It takes the contents
143              of the specified file and assign them  to  that  parameter,  for
144              whatever use by the engine. The HTML engine will insert the text
145              just after the tag <body>.  If navigation  buttons  are  present
146              (see option -nav below), then the HTML generated for them is ap‐
147              pended to the header data originating here before the final  as‐
148              signment to the parameter.
149
150              When used multiple times only the last definition is relevant.
151
152       -footer file
153              Like  -header,  except that: Any navigation buttons are ignored,
154              the corresponding required engine parameter is  named  "footer",
155              and the data is inserted just before the tag </body>.
156
157              When used multiple times only the last definition is relevant.
158
159       -style file
160              This  option can be used if and only if the selected format pro‐
161              vides an engine parameter named "meta". When specified  it  will
162              generate  a  piece  of  HTML  code  declaring  the  file  as the
163              stylesheet for the generated document and assign that to the pa‐
164              rameter.  The  HTML  engine  will insert this inot the document,
165              just after the tag <head>.
166
167              When processing an input directory the stylesheet file is copied
168              into  the  output directory and the generated HTML will refer to
169              the copy, to make the result more self-contained. When  process‐
170              ing  an input file we have no location to copy the stylesheet to
171              and so just reference it as specified.
172
173              When used multiple times only the last definition is relevant.
174
175       -toc path
176              This option specifies a doctoc file to use for the table of con‐
177              tents instead of generating our own.
178
179              When used multiple times only the last definition is relevant.
180
181       -pre+toc label path|text
182
183       -post+toc label path|text
184              This  option specifies additional doctoc files (or texts) to use
185              in the navigation bar.
186
187              Positioning and handling of multiple uses is  like  for  options
188              -prenav and -postnav, see below.
189
190       -nav label url
191
192       -prenav label url
193              Use  this  option  to  specify a navigation button with label to
194              display and the url to link to. This option can be used  if  and
195              only  if  the selected format provides an engine parameter named
196              "header". The HTML generated for this is  appended  to  whatever
197              data  we  got from option -header before it is inserted into the
198              generated documents.
199
200              When used multiple times all definitions  are  collected  and  a
201              navigation  bar  is  created, with the first definition shown at
202              the left edge and the last definition to the right.
203
204              The url can be relative. In that case it is assumed to be  rela‐
205              tive  to  the  main  files  (TOC and Keyword index), and will be
206              transformed for all others to still link properly.
207
208       -postnav label url
209              Use this option to specify a navigation  button  with  label  to
210              display  and  the url to link to. This option can be used if and
211              only if the selected format provides an engine  parameter  named
212              "header".  The  HTML  generated for this is appended to whatever
213              data we got from option -header before it is inserted  into  the
214              generated documents.
215
216              When  used  multiple  times  all definitions are collected and a
217              navigation bar is created, with the last definition shown at the
218              right edge and the first definition to the left.
219
220              The  url can be relative. In that case it is assumed to be rela‐
221              tive to the main files (TOC and  Keyword  index),  and  will  be
222              transformed for all others to still link properly.
223
224   FORMATS
225       At  first  the  format argument will be treated as a path to a tcl file
226       containing the code for the requested formatting engine.  The  argument
227       will be treated as the name of one of the predefined formats listed be‐
228       low if and only if the path does not exist.
229
230       Note a limitation: If treating the format as path to the tcl script im‐
231       plementing  the engine was sucessful, then this script has to implement
232       not only the engine API for doctools, i.e.  doctools_api, but for  doc‐
233       toc_api  and docidx_api as well. Otherwise the generation of a table of
234       contents and of a keyword index will fail.
235
236       List of predefined formats, i.e. as provided by the package doctools:
237
238       nroff  The processor generates *roff output, the  standard  format  for
239              unix manpages.
240
241       html   The processor generates HTML output, for usage in and display by
242              web browsers. This engine is currently the  only  one  providing
243              the  various  engine parameters required for the additional cus‐
244              tomaization of the output.
245
246       tmml   The processor generates TMML output, the Tcl Manpage Markup Lan‐
247              guage, a derivative of XML.
248
249       latex  The processor generates LaTeX output.
250
251       wiki   The processor generates Wiki markup as understood by wikit.
252
253       list   The  processor  extracts the information provided by manpage_be‐
254              gin.  This format is used internally to extract  the  meta  data
255              from  which both table of contents and keyword index are derived
256              from.
257
258       null   The processor does not generate any output. This  is  equivalent
259              to validate.
260
261   DIRECTORY STRUCTURES
262       In  this  section we describe the directory structures generated by the
263       application under output when processing all documents in  an  inputdi‐
264       rectory. In other words, this is only relevant to the use cases [2] and
265       [3].
266
267       [2]    The following directory structure is created when  processing  a
268              single  set  of input documents.  The file extension used is for
269              output in HTML, but that is not relevant to  the  structure  and
270              was just used to have proper file names.
271
272
273                  output/
274                      toc.html
275                      index.html
276                      files/
277                          path/to/FOO.html
278
279
280              The  last line in the example shows the document generated for a
281              file FOO located at
282
283
284                  inputdirectory/path/to/FOO
285
286
287       [3]    When merging many packages into a unified set of  documents  the
288              generated directory structure is a bit deeper:
289
290
291                  output
292                      .toc
293                      .idx
294                      .tocdoc
295                      .idxdoc
296                      .xrf
297                      toc.html
298                      index.html
299                      FOO1/
300                          ...
301                      FOO2/
302                          toc.html
303                          files/
304                              path/to/BAR.html
305
306
307              Each  of the directories FOO1, ... contains the documents gener‐
308              ated for the package FOO1, ... and follows the  structure  shown
309              for  use  case  [2]. The only exception is that there is no per-
310              package index.
311
312              The files ".toc", ".idx", and ".xrf" contain the internal status
313              of the whole output and will be read and updated by the next in‐
314              vokation. Their contents will not be  documented.  Remove  these
315              files  when  all  packages  wanted for the output have been pro‐
316              cessed, i.e. when the output is complete.
317
318              The files ".tocdoc", and ".idxdoc", are  intermediate  files  in
319              doctoc  and docidx markup, respectively, containing the main ta‐
320              ble of contents and keyword index for the set of  documents  be‐
321              fore  their  conversion  to  the chosen output format.  They are
322              left in place, i.e. not deleted, to serve as  demonstrations  of
323              doctoc and docidx markup.
