# Configuration
Gitlint can be configured through different means.
# Config files #
You can modify gitlint's behavior by adding a ```.gitlint``` file to your git repository.
Generate a default ```.gitlint``` config file by running:
```bash
gitlint generate-config
```
You can also use a different config file like so:
```bash
gitlint --config myconfigfile.ini
```
The block below shows a sample ```.gitlint``` file. Details about rule config options can be found on the
[Rules](rules.md) page, details about the ```[general]``` section can be found in the
[General Configuration](configuration.md#general-configuration) section of this page.
```ini
# Edit this file as you like.
#
# All these sections are optional. Each section with the exception of [general] represents
# one rule and each key in it is an option for that specific rule.
#
# Rules and sections can be referenced by their full name or by id. For example
# section "[body-max-line-length]" could be written as "[B1]". Full section names are
# used in here for clarity.
# Rule reference documentation: http://jorisroovers.github.io/gitlint/rules/
#
# Use 'gitlint generate-config' to generate a config file with all possible options
[general]
# Ignore certain rules (comma-separated list), you can reference them by their
# id or by their full name
ignore=title-trailing-punctuation, T3
# verbosity should be a value between 1 and 3, the commandline -v flags take
# precedence over this
verbosity = 2
# By default gitlint will ignore merge, revert, fixup and squash commits.
ignore-merge-commits=true
ignore-revert-commits=true
ignore-fixup-commits=true
ignore-squash-commits=true
# Ignore any data send to gitlint via stdin
ignore-stdin=true
# Fetch additional meta-data from the local repository when manually passing a
# commit message to gitlint via stdin or --commit-msg. Disabled by default.
staged=true
# Enable debug mode (prints more output). Disabled by default.
debug=true
# Enable community contributed rules
# See http://jorisroovers.github.io/gitlint/contrib_rules for details
contrib=contrib-title-conventional-commits,CC1
# Set the extra-path where gitlint will search for user defined rules
# See http://jorisroovers.github.io/gitlint/user_defined_rules for details
extra-path=examples/
# This is an example of how to configure the "title-max-length" rule and
# set the line-length it enforces to 80
[title-max-length]
line-length=80
[title-must-not-contain-word]
# Comma-separated list of words that should not occur in the title. Matching is case
# insensitive. It's fine if the keyword occurs as part of a larger word (so "WIPING"
# will not cause a violation, but "WIP: my title" will.
words=wip
[title-match-regex]
# python like regex (https://docs.python.org/2/library/re.html) that the
# commit-msg title must be matched to.
# Note that the regex can contradict with other rules if not used correctly
# (e.g. title-must-not-contain-word).
regex=^US[0-9]*
[body-max-line-length]
line-length=120
[body-min-length]
min-length=5
[body-is-missing]
# Whether to ignore this rule on merge commits (which typically only have a title)
# default = True
ignore-merge-commits=false
[body-changed-file-mention]
# List of files that need to be explicitly mentioned in the body when they are changed
# This is useful for when developers often erroneously edit certain files or git submodules.
# By specifying this rule, developers can only change the file when they explicitly reference
# it in the commit message.
files=gitlint/rules.py,README.md
[author-valid-email]
# python like regex (https://docs.python.org/2/library/re.html) that the
# commit author email address should be matched to
# For example, use the following regex if you only want to allow email addresses from foo.com
regex=[^@]+@foo.com
[ignore-by-title]
# Ignore certain rules for commits of which the title matches a regex
# E.g. Match commit titles that start with "Release"
regex=^Release(.*)
# Ignore certain rules, you can reference them by their id or by their full name
# Use 'all' to ignore all rules
ignore=T1,body-min-length
[ignore-by-body]
# Ignore certain rules for commits of which the body has a line that matches a regex
# E.g. Match bodies that have a line that that contain "release"
# regex=(.*)release(.*)
#
# Ignore certain rules, you can reference them by their id or by their full name
# Use 'all' to ignore all rules
ignore=T1,body-min-length
# This is a contrib rule - a community contributed rule. These are disabled by default.
# You need to explicitly enable them one-by-one by adding them to the "contrib" option
# under [general] section above.
[contrib-title-conventional-commits]
# Specify allowed commit types. For details see: https://www.conventionalcommits.org/
types = bugfix,user-story,epic
```
# Commandline config #
You can also use one or more ```-c``` flags like so:
```
$ gitlint -c general.verbosity=2 -c title-max-length.line-length=80 -c B1.line-length=100
```
The generic config flag format is ```-c <rule>.<option>=<value>``` and supports all the same rules and options which
you can also use in a ```.gitlint``` config file.
# Commit specific config #
You can also configure gitlint by adding specific lines to your commit message.
For now, we only support ignoring commits by adding ```gitlint-ignore: all``` to the commit
message like so:
```
WIP: This is my commit message
I want gitlint to ignore this entire commit message.
gitlint-ignore: all
```
```gitlint-ignore: all``` can occur on any line, as long as it is at the start of the line.
You can also specify specific rules to be ignored as follows:
```
WIP: This is my commit message
I want gitlint to ignore this entire commit message.
gitlint-ignore: T1, body-hard-tab
```
# Configuration precedence #
gitlint configuration is applied in the following order of precedence:
1. Commit specific config (e.g.: ```gitlint-ignore: all``` in the commit message)
2. Configuration Rules (e.g.: [ignore-by-title](/rules/#i1-ignore-by-title))
3. Commandline convenience flags (e.g.: ```-vv```, ```--silent```, ```--ignore```)
4. Commandline configuration flags (e.g.: ```-c title-max-length=123```)
5. Configuration file (local ```.gitlint``` file, or file specified using ```-C```/```--config```)
6. Default gitlint config
# General Options
Below we outline all configuration options that modify gitlint's overall behavior. These options can be specified
using commandline flags or in ```[general]``` section in a ```.gitlint``` configuration file.
