NAME
dwww - access documentation via WWW
SYNOPSIS
http://localhost/dwww/index.html
DESCRIPTION
A typical Linux system has documentation in many formats (manual pages, Info files,
READMEs, and so on). dwww makes it possible to access all of these via the same inter‐
face, a WWW browser. This makes it easier to use the documentation.
dwww consists of several programs:
cgi-bin/dwww
Run by the WWW server when user requests document via dwww. Parses the request and
runs dwww-convert(8) or dwww-find(8) with suitable arguments. Installed in the
server's cgi-bin directory.
dwww-convert(8)
Converts any document to HTML.
dwww-format-man(8)
Auxiliary program to convert man pages or text files to HTML.
dwww-find(8)
Searches for documentation.
dwww-quickfind(8)
Used by dwww-find(8) to quickly find which package a program belongs to.
dwww-cache(8)
Manages the cache of converted documents.
dwww-refresh-cache(8)
Cleans outdated documents from the cache.
dwww-build(8)
Builds static lists of manual pages. Needs to be re-run whenever documents are
installed or removed. (In default configuration is called by the dwww daily cron
job).
dwww-build-menu(8)
Builds the Debian Documentation Menu pages. Needs to be re-run whenever documents
are installed or removed. (In default configuration is called by the
install-docs(8) or by the dwww daily cron job).
dwww-index++(8)
Uses index++(1) to build index of the documentation registered with doc-base. In
default configuration is called be the dwww weekly cron job.
For speed reasons, the converted documents are stored in /var/cache/dwww. The cache is
cleaned by dwww-refresh-cache(8) of old documents to keep it from growing too large.
CONFIGURATION
dwww is configured via the /etc/dwww/dwww.conf file. That file is a Bourne shell
(/bin/sh) script that defines some or all the following variables (defaults are used if
the file doesn't exist, or doesn't define the variable).
Basic configuration variables
These variables can be also configured by debconf script. You can change them using the
following command:
dpkg-reconfigure dwww
DWWW_SERVERNAME
Name of the www server. Default is localhost.
DWWW_SERVERPORT
Port on which the www server listen to. Default is 80.
DWWW_USEHTTPS
If enabled, dwww(1) will connect to DWWW_SERVERNAME:DWWW_SERVERPORT through the
HTTPS protocol. Default is no.
DWWW_DOCROOTDIR
The document root for web server. Default is /var/www.
DWWW_CGIDIR
The directory which contains the CGI scripts for your web server. Default is
/usr/lib/cgi-bin.
DWWW_CGIUSER
Name of the user that the web server uses to execute CGI scripts. Default is
www-data.
Browser variables
DWWW_BROWSER
Web-browser used by dwww(1) to load dwww main page.
DWWW_X11_BROWSER
Web-browser used by dwww(1) to load dwww main page when in X11.
Path variables
DWWW_DOCPATH
Colon-delimited list of directories from which dwww-convert(8) supplies files. For
security reasons, it will refuse to convert files outside the directories named by
this variable. Default is /usr/share/doc:/usr/share/info:/usr/share/man:
/usr/local/share/doc:/usr/local/share/info:/usr/local/share/man: /usr/share/com‐
mon-licenses.
DWWW_ALLOWEDLINKPATH
Colon-delimited list of directories which can be targets of symlinks from files
from directories inside DWWW_DOCPATH. Default value is
/usr/share:/usr/lib:/usr/local/share:/var/www.
For example, /usr/share/doc/package/foo.html may be symlinked to a file
/usr/share/package/foo.html, and this file can be displayed by dwww.
Cache files locations
DWWW_QUICKFIND_DB
Location of the installed packages and programs cache file, generated by
dwww-refresh-cache(8) with the help of dwww-quickfind(8). Default is
/var/cache/dwww/quickfind.dat.
DWWW_DOCBASE2PKG_DB
Location of the cache file, which maps installed doc-base files to packages names,
used by the dwww-build-menu(8). Default is /var/cache/dwww/docbase2pkg.dat.
DWWW_REGDOCS_DB
Location of doc-base registered documents contents cache. The cache is generated by
dwww-build-menu(8) and read by dwww-find(8) Default is /var/cache/dwww/regdocs.dat.
Documentation indexing variables
DWWW_INDEX_DOCUMENTATION
If this variable is set to yes (default), and the swish++ package is installed,
then dwww-index++(8) will generate index of registered documentation.
DWWW_INDEX_FULL_TIME_INTERVAL
Specifies how often (in days) dwww-index++(8) will generate full index of documen‐
tation. The default value is 28.
DWWW_INDEX_INCREMENTAL_TIME_INTERVAL
Specifies how often (in days) dwww-index++(8) will run incremental indexing of new
documentation files. The default value is 7.
DWWW_MERGE_MAN2HTML_INDEX
If this variable is set to yes, then while generating index of registered docu‐
ments, dwww-index++(8) will use man pages index generated by man2html package, if
it's available.
Other variables
DWWW_KEEPDAYS
How many days should dwww-refresh-cache(8) keep documents that have not been
accessed? Default is 10 days.
DWWW_TMPDIR
Directory used by dwww-build(8) and dwww-build-menu(8) to temporally store the web
pages it generates. Default is /var/lib/dwww. For security reason any public
writable directory like /tmp should not be used.
DWWW_USEFILEURL
If this variable is set, dwww will use file:/ style URLs to access html files -
bypassing the CGI script. This is faster on slow machines. Of course, you will
not be able to read the html documentation on a non-local machine. Default is to
not enable this feature.
DWWW_TITLE
Title to appear on dwww generated files. Default is dwww: $(hostname)
DWWW_USE_CACHE
If this variable is set to yes (default), dwww will cache accessed documents in
/var/cache/dwww/db. See dwww-cache(8).
Deprecated variables
Since version 1.10, dwww no longer uses the following variables: DWWW_HTMLDIR,
DWWW_MAN2HTML, DWWW_TEXT2HTML, DWWW_DIR2HTML.
CUSTOMISING DWWW PAGES LAYOUT
dwww uses a CSS file for managing the layout of the pages it generates. The file is built
from two other files, namely /usr/share/dwww/dwww.css, which is a global one, provided by
the package, and /etc/dwww/dwww-user.css, a local one, that can be provided by the user to
override settings from the former file. The latter file does not exist by default, but
when it exists, dwww-build(8) will append its contents at the end of generated file.
Since web browsers tend to use the last one setting defined for a given CSS element, this
has the expected effect of customisation.
Example
To use some image as a background for dwww pages, please put something like this in
/etc/dwww/dwww-user.css:
body { background: url('http://host/path/to/background.png')
repeat; }
table,pre,code,tt { opacity: 0.7; }
Please make sure to run dwww-build(8) afterwards.
FILES
/etc/dwww/dwww.conf
Configuration file for dwww. It's not necessary for this file to exist, there are
sensible defaults for everything.
/etc/dwww/apache.conf
Default configuration file for various apache-based web servers. The dwww package
post-installation script creates symlinks from /etc/apache*/conf.d/dwww to this
file.
/etc/dwww/dwww-user.css
If such a file exists, its contents will be appended to the dwww.css file. This
allows local administrators to customise dwww pages layout.
/etc/cron.daily/dwww
Dwww daily cron job, which rebuilds cache directory and dwww HTML pages.
/etc/cron.weekly/dwww
Dwww weekly cron job. Uses dwww-index++(8) to rebuild registered documentation
index.
/var/cache/dwww
Directory, where are placed various cache files generated and used by dwww.
/var/cache/dwww/db
Cache for the converted documents.
/usr/share/dwww
Templates for the dwww web pages (used by dwww-build(8) and others).
/var/lib/dwww
The dwww pages. The server's document root directory should have a link to this
directory.
