NAME
ldptool - DocBook, Linuxdoc and Asciidoc build/publishing tool.
SYNOPSIS
ldptool [options] [pathname [...]]
DESCRIPTION
ldptool creates chunked HTML, single-page HTML, PDF and plain text outputs for each source document it is
passed as a pathname. See Source document discovery.
If it is not passed any arguments, ldptool will collect all of the directories specified with the
--sourcedir option and scan through these directories looking for valid source documents.
The action taken depends on the options passed to the utility. If no options are passed, then the
default --build action will be attempted. The options controlling the overall program are described in
the sections Action options and Main options. All other options are relegated to the tail of the
manpage, because they are merely configurables for individual document processors.
The ldptool can:
• generate an inventory from multiple source directories (--sourcedir)
• crawl through a single output collection (--pubdir)
• match the sources to the outputs (based on document stem name)
• describe the collection by type and status (--summary)
• list out individual document type and status (--list)
• describe supported source formats (--formats)
• describe the meaning of document status (--statustypes)
• build the expected (non-configurable) set of outputs (--build)
• build and publish the outputs (--publish)
• produce runnable shell script to STDOUT (--script)
• generate configuration files that it can then take as input
ACTION OPTIONS
-h, --help
show a help message and exit
-b, --build
Build LDP documentation into the --builddir and exit. This is the default action if no other
action is specified.
-p, --publish
Build LDP documentation into the --builddir. If all builds are successful, then copy the result
for each source document into the --pubdir, effectively replacing (and deleting) the older
documents; finally, remove --builddir, if empty.
-S, --script
Print a runnable bash script to STDOUT. This will produce a shell script showing what would be
executed upon --build.
-l, --detail, --list
Examine the various SOURCEDIRs and the PUBDIR and generate a report showing the FORMAT of the
source document and STATUS of the document. Add the --verbose flag for more information.
-t, --summary
Examine the various SOURCEDIRs and the PUBDIR and generate a short report summarizing documents by
STATUS and by DOCTYPE. Add the --verbose flag for more information.
-T, --doctypes, --formats, --format, --list-doctypes, --list-formats
List the supported DOCTYPEs; there is one processor for each DOCTYPE.
--statustypes, --list-statustypes
List the possible document STATUS types. There are only seven basic status types, but several
synonyms and groups of STATUS types (internally called 'classes').
MAIN OPTIONS
-s, --sourcedir, --source-dir, --source-directory SOURCEDIR (default: None)
Specify the name of a SOURCEDIR which contains source documents. See also Source document
discovery.
The --sourcedir option may be used more than once.
-o, --pubdir, --output, --outputdir, --outdir PUBDIR (default: None)
Specify the the name of a PUBDIR. Used as the publication if the build succeeds. When --publish
is used with --pubdir, the output of a successful document build will be used to replace any
existing document output directory in PUBDIR.
-d, --builddir, --build-dir, --build-directory BUILDDIR (default: 'ldptool-build')
Specify the name of a BUILDDIR. A scratch directory used to build each source document; directory
is temporary and will be removed if the build succeeds AND --publish has been requested. Under
the --build action, all output directories and contents remain in the BUILDDIR for inspection.
--verbose [True | False] (default: False)
Provide more information in --list and --detail actions. The option can be thrown without an
argument which is equivalent to True. To allow the CLI to supersede environment or configuration
file values, --verbose false is also supported.
--skip [STEM | DOCTYPE | STATUS]
Specify a source document name, document type or document status to skip during processing. Each
document is known by its STEM (see also Source document discovery), its document DOCTYPE (see list
below), and by the document STATUS (see list below).
The --skip option may be used more than once.
DOCTYPE can be one of:
Asciidoc, Docbook4XML, Docbook5XML, DocbookSGML, or Linuxdoc (See also output of
--doctypes)
STATUS can be one of:
source, sources, output, outputs, published, stale, broken, new orphan, orphans, orphaned,
problems, work, all (See also output of --statustypes)
--resources RESOURCEDIR (default: ['images', 'resources'])
Some source documents provide images, scripts and other content. These files are usually stored
in a directory such as ./images/ that need to be copied intact into the output directory. Adjust
the set of resource directories wyth this option.
The --resources option may be used more than once.
--loglevel LOGLEVEL (default: ERROR)
set the loglevel to LOGLEVEL; can be passed as numeric or textual; in increasing order: CRITICAL
(50), ERROR (40), WARNING (30), INFO (20), DEBUG (10); N.B. the text names are not case-sensitive:
'info' is OK
-c, --configfile, --config-file, --cfg CONFIGFILE (default: None)
Specify the name of a CONFIGFILE containing parameters to be read for this invocation; an
INI-style configuration file. A sample can be generated with --dump-cfg. Although only one
CONFIGFILE can be specified via the environment or the command-line, the system config file
(/etc/ldptool/ldptool.ini) is always read.
--dump_cli, --dump-cli
Produce the resulting, merged configuration as in CLI form. (After processing all configuration
sources (defaults, system configuration, user configuration, environment variables, command-line.)
--dump_env, --dump-env
Produce the resulting, merged configuration as a shell environment file.
--dump_cfg, --dump-cfg
Produce the resulting, merged configuration as an INI-configuration file.
--debug_options, --debug-options
Provide lots of debugging information on option-processing; see also --loglevel debug.
SOURCE DOCUMENT DISCOVERY
Almost all documentation formats provide the possibility that a document can span multiple files.
Although more than half of the LDP document collection consists of single-file HOWTO contributions, there
are a number of documents that are composed of dozens, even hundreds of files. In order to accommodate
both the simple documents and these much more complex documents, LDP adopted a simple (unoriginal) naming
strategy to allow a single document to span multiple files:
Each document is referred to by a stem, which is the filename without any
extension. A single file document is simple STEM.EXT. A document that
requires many files must be contained in a directory with the STEM name.
Therefore, the primary source document will always be called either STEM.EXT
or STEM/STEM.EXT.
(If there is a STEM/STEM.xml and STEM/STEM.sgml in the same directory, that is an error, and ldptool will
freak out and shoot pigeons.)
During document discovery, ldptool will walk through all of the source directories specified with
--sourcedir and build a complete list of all identifiable source documents. Then, it will walk through
the publication directory --pubdir and match up each output directory (by its STEM) with the
corresponding STEM found in one of the source directories.
Then, ldptool can then determine whether any source files are newer. It uses content-hashing, i.e. MD5,
and if a source file is newer, the status is stale. If there is no matching output, the source file is
new. If there's an output with no source, that is in orphan. See the --statustypes output for the full
list of STATUS types.
EXAMPLES
To build and publish a single document:
$ ldptool --publish DocBook-Demystification-HOWTO
$ ldptool --publish ~/vcs/LDP/LDP/howto/docbook/Valgrind-HOWTO.xml
To build and publish anything that is new or updated work:
$ ldptool --publish
$ ldptool --publish work
To (re-)build and publish everything, regardless of state:
$ ldptool --publish all
To generate a specific output (into a --builddir):
$ ldptool --build DocBook-Demystification-HOWTO
To generate all outputs into a --builddir (should exist):
$ ldptool --builddir ~/tmp/scratch-directory/ --build all
To build new/updated work, but pass over a trouble-maker:
$ ldptool --build --skip HOWTO-INDEX
To loudly generate all outputs, except a trouble-maker:
$ ldptool --build all --loglevel debug --skip HOWTO-INDEX
To print out a shell script for building a specific document:
$ ldptool --script TransparentProxy
$ ldptool --script ~/vcs/LDP/LDP/howto/docbook/Assembly-HOWTO.xml
ENVIRONMENT
The ldptool accepts configuration via environment variables. All such environment variables are prefixed
with the name LDPTOOL_.
The name of each variable is constructed from the primary command-line option name. The -b is better
known as --builddir, so the environment variable would be LDPTOOL_BUILDDIR. Similarly, the environment
variable names for each of the handlers can be derived from the name of the handler and its option. For
example, the Asciidoc processor needs to have access to the xmllint and asciidoc utilities.
The environment variable corresponding to the CLI option --asciidoc-xmllint would be
LDPTOOL_ASCIIDOC_XMLLINT. Similarly, --asciidoc-asciidoc should be LDPTOOL_ASCIIDOC_ASCIIDOC.
Variables accepting multiple options use the comma as a separator:
LDPTOOL_RESOURCES=images,resources
The complete listing of possible environment variables with all current values can be printed by using
ldptool --dump-env.
CONFIGURATION FILE
The system-installed configuration file is /etc/ldptool/ldptool.ini. The format is a simple INI-style
configuration file with a block for the main program and a block for each handler. Here's a partial
example:
[ldptool]
resources = images,
resources
loglevel = 40
[ldptool-asciidoc]
asciidoc = /usr/bin/asciidoc
xmllint = /usr/bin/xmllint
Note that the comma separates multiple values for a single option (resources) in the above config
fragment.
The complete, current configuration file can be printed by using ldptool --dump-cfg.
CONFIGURATION OPTION FRAGMENTS FOR EACH DOCTYPE HANDLER
Every source format has a single handler and each DOCTYPE handler may require a different set of
executables and/or data files to complete its job. The defaults depend on the platform and are detected
at runtime. In most cases, the commands are found in /usr/bin (see below). The data files, for example
the LDP XSL files and the docbook.rng, may live in different places on different systems.
If a given DOCTYPE handler cannot find all of its requirements, it will complain to STDERR during
execution, but will not abort the rest of the run.
If, for some reason, ldptool cannot find data files, but you know where they are, consider generating a
configuration file with the --dump-cfg option, adjusting the relevant options and then passing the
--configfile your.ini to specify these paths.
