tartufo
has a wide variety of options to customize its operation available
:doc:`on the command line<usage>`. Some of these options, however, can be a bit
unwieldy and lead to an overly cumbersome command. It also becomes difficult to
reliably reproduce the same command in all environments when done this way.
To help with these problems, tartufo
can also be configured by way of a
configuration file! You can tell tartufo what config file to use, or, it will automatically discover one
for you. Starting in the current working directory, and traversing backward up
the directory tree, it will search for both a tartufo.toml
and a
pyproject.toml
. The latter is searched for as a matter of convenience for
Python projects, such as tartufo
itself. For an example of the tree
traversal, let's say you running tartufo
from the directory
/home/my_user/projects/my_project
. tartufo
will look for the
configuration files first in this directory, then in /home/my_user/projects/
,
then in /home/my_user
, etc.
Within these files, tartufo
will look for a section labeled
[tool.tartufo]
to find its configuration, and will load all items from there
just as though they had been specified on the command line. This file must be
written in the TOML format, which should look mostly familiar if you have
dealt with any other configuration file format before.
All command line options can be specified in the configuration file, with or without the leading dashes, and using either dashes or underscores for word separators. When the configuration is read in, this will all be normalized automatically. For example, the configuration for tartufo itself looks like this:
[tool.tartufo]
repo-path = "."
json = false
regex = true
entropy = true
Note that all options specified in a configuration file are treated as defaults, and will be overridden by any options specified on the command line.
