       debtags - Debian Package Tags support tools

DESCRIPTION

       usage: debtags [-h] [--version] [--verbose] [--debug]

              {tag,cat,grep,check,diff,mkpatch,search,dumpavail,show,submit,tagcat,tagshow,tagsearch,update,vocfilter}
              ...

       Command line interface to access and manipulate Debian Package Tags

   optional arguments:
       -h, --help
              show this help message and exit

       --version
              show program's version number and exit

       --verbose, -v
              enable verbose output

       --debug
              enable debugging output (including verbose output)

   subcommands:
              valid subcommands

       {tag,cat,grep,check,diff,mkpatch,search,dumpavail,show,submit,tagcat,tagshow,tagsearch,update,vocfilter}
              additional help

       tag    (not implemented anymore)

       cat (grep)
              output the lines of the full package tag database that match  the  given  tag  expression.  A  tag
              expression  (given as a single argument) is an arbitrarily complex binary expression of tag names.
              For example: role::program && ((use::editing || use::viewing) && !works-with::text)

       check  Check that all the tags in the given tagged collection are present in the tag  vocabulary.  Checks
              the main database if no file is specified

       diff (mkpatch)
              Create  a  tag  patch between the current tag database and the tag collection [filename]. Standard
              input is used if filename is not specified

       search (dumpavail)
              Output the packages matching the given tag expression

       show   (deprecated) mostly the same as apt-cache show <pkgnames>

       submit (no longer supported) see https://debtags.debian.org/api/patch for patch submit.

       tagcat Output the tag vocabulary

       tagshow
              Show the vocabulary information about a tag

       tagsearch
              Show a summary of all tags whose data contains the given strings

       update Updates the package tag database  (requires  root)  Collect  package  tag  data  from  apt  cache,
              regenerate the debtags tag database and main index. It needs to be run as root

       vocfilter
              Filter  out  the  tags that are not found in the given vocabulary file debtags manages package tag
              data in a debian system and performs basic queries on it.

       debtags can be used to perform basic queries on the Debtags system: the vocabulary can  be  queried  with
       the tagshow and tagsearch commands; a package tag database can be checked against the vocabulary with the
       check command; the whole collection can be copied to standard output to  be  processed  with  tagcoll  or
       other  tools  by  the cat command; packages can be searched by tags using the grep command. Finally, tags
       can be listed with tag ls, edited with the tag add and tag rm, and submitted to the Debtags database with
       submit.

       The  update  command  can  be used to download extra tags as listed in /etc/debtags/sources.list: see the
       contents of that file for more information.

FILES

       /var/lib/debtags/vocabulary
              The normative tag vocabulary

       /var/lib/debtags/package-tags
              The system package tags database, only  kept  as  an  easily  parsable  reference.   In  the  same
              directory there is a the binary index with the same content, used by applications for fast access.

       /etc/debtags/sources.list
              The list of sources to build the package tags database from

EXAMPLES

       Here are some example invocations of debtags:

         # Update the package tag database
         debtags update

         # Show apt-cache information about the mutt package,
         # adding tag information
         debtags show mutt

         # Search the tag vocabulary for mail-related tags
         debtags tagsearch mail

         # Output a list of all packages which can edit raster images, excluding
         # shared libraries and dummy packages
         debtags search "use::editing && works-with::image:raster && \
                       ! (role::shared-lib || role::dummy)"

         # Show all mail clients
         debtags search 'works-with::mail && network::client'

         # Output the collection of all mail clients, ready to be reprocessed via
         # tagcoll
         debtags grep 'works-with::mail && network::client'

         # Produce an easily navigable hierarchy with the collection data
         debtags cat | tagcoll hierarchy

         # Produce a local tag patch
         debtags cat > work-tags
         ...edit work-tags...
         debtags diff work-tags > my-tagpatch

         # Submit the patch
         debtags submit my-tagpatch

         # Edit the tags of a package (the patch will be stored in ~/.debtags/patch)
         # then send your changes
         debtags tag add debtags implemented-in::c++ interface::commandline
         debtags tag rm debtags devel::buildtools
         debtags submit
