Usage¶
Example¶
You can do a test run of this software against your local APT cache, like this:
$ ( cd /var/cache/apt/archives/ && dpkg-scanpackages . | sudo tee Packages > /dev/null )
dpkg-scanpackages: warning: package tar (filename ./tar_1.27.1-2+b1_amd64.deb) is repeat;
dpkg-scanpackages: warning: ignored that one and using data from ./tar_1.27.1-2+deb8u1_amd64.deb!
$ debmans -m /var/cache/apt/archives -o html -v --progress extract render site serve
extracting files matching patterns: (u'man/(?:\\w+/)?man[1-9]/.+\\.[1-9]\\w*(?:\\.gz)?$',) in mirror /var/cache/apt/archives

Serving HTTP on 0.0.0.0 port 8000...
Your rendered manpages will be available at <http://localhost:8000/>.
Note that you will need dpkg-scanpackages
from the
dpkg-dev package to run the
above test. The warnings can be safely ignored. debmans
doesn’t
normally require dpkg-dev
in operation if you use a properly
configured mirror.
Common tasks¶
A more normal run would be to run on a regular mirror. This will extract all manpages from the given mirror and convert to HTML:
debmans --mirror /srv/mirror --output static extract render
This can be ran repeatedly and only extracted manpages will be rendered.
Extraction only¶
You can also run the process step by step, for example, this will only extract the manpages:
debmans -m /srv/mirror -o html extract
Note that extract creates a cache in the output directory to avoid
re-extracting already found archives. Render also uses a caching
mechanism by not converting to HTML if the HTML version is newer than
the manpage. Those mechanisms can be disabled with --no-cache
.
debmans -m /srv/mirror -o html --no-cache extract
You can make a trial run with the -n
flag and enable more verbose
logging:
debmans -v -n -m /srv/mirror -o manpages extract
Rendering only¶
Rendering the pages can be done separately with:
debmans -o html render --srcdir manpages
This is especially important if the extraction process was interrupted, as only part of the manpages will be rendered on subsequent runs.
Manpages are currently rendered with
man2html but
this can be changed with the -r
flag, although no other renderer has
been tested and the output may not be compatible with man2html
.
Static pages rendering¶
The templating engine is fairly simple, based on Jinja2, which uses
standard {{foo}}
placeholders. The template is in
static/template.html
and should be following debian.org’s graphic
design conventions.
This should generate the markdown files:
debmans -o html site
Use --prefix
if the directory is not at the root of the host.
Installation¶
debmans
can be installed through pip with:
pip install debmans
Source code can also be found on Gitlab with Git or as a tarball, or on Debian’s collab-maint repository.
The source code is should be installed with:
./setup.py install
It can also be ran from the source tree directly with:
python -m debmans render
The dependencies are listed in the setup.py
file.

Parts of this software were inspired by a review of existing tools, most
notably the Ubuntu manpages
converter and
dgilman’s converter. The
sources.debian.net service source code
and design was also directly used in some parts, which is partly why
debmans
is licensed under the AGPL.
