.. _writing-fixers:



Writing new fixers

------------------



For a more extensive write-up, see the

[guide on writing fixers](doc/fixer-writing-guide.rst).



Ideally, fixers target a particular set of lintian tags. This is not strictly

required, but makes it possible to easily find all packages that a particular

fixer can be used on.



Each fixer is a simple script that lives under ``fixers``. Scripts should

be registered in the ``index.desc`` file in the same directory.



A fixer is run in the root directory of a package, where it can make changes

it deems necessary. If a fixer can not provide any improvements, it can simply

leave the working tree untouched - lintian-brush will not create any commits for it

or update the changelog. If exits with a non-zero return code, whatever changes

it has made will be discarded and the fixer will be reported as having failed.



The following additional environment variables are set:



 * ``DEB_SOURCE``: The name of the source package that is being edited.

 * ``CURRENT_VERSION``: Package version that is being edited.

 * ``COMPAT_RELEASE``: Debian release to be compatible with. Usually ``sid``

   when --modern was specified and the name of the current stable release otherwise.

 * ``NET_ACCESS``: Whether the fixer is allowed to make network connections

   (e.g. sending HTTP requests). Used by --disable-net-access and the testsuite.

   Set to either ``allow`` or ``disallow``.

 * ``OPINIONATED``: Set to ``yes`` or ``no``. If ``no``, fixers are not expected

   to make changes in which there is no obvious single correct fix.



For fixer written in python, the ``lintian_brush.fixer`` module can be used for

convenient access to these variables.



A fixer should write a short description of the changes it has made to standard

out; this will be used for the commit message.



It can include optional metadata in its output::



 * ``Fixed-Lintian-Tags:`` followed by a comma-separated list of lintian tags

   that it claims to have fixed. This will make lintian-brush include

   links to documentation about the fixed lintian tags. In the future,

   it may also support building the package to verify the lintian tag

   is actually resolved.



 * ``Certainty:`` followed by ``certain``, ``confident``, ``likely`` or

   ``possible``, indicating how certain the fixer is that the fix was the right

   one.



The default minimum certainty level is "certain"; any incorrect change made

with certainty "certain" is considered *at least* a normal-severity bug.



The easiest way to test fixers is to create a skeleton *in* and *out* source

tree under ``tests/FIXER-NAME/TEST-NAME``. The ``in`` directory should contain

the tree to run the fixer on, and ``out`` contains the directory after it has

run. It's fine to create directories with only one or two control files, if the

fixer only needs those. To run the tests for a single fixer, you can use "make

check-fixer-$NAME".
