Examples
This extension uses doublestar for matching paths changed in your commit range, refer to their documentation for all supported patterns.
include
Only run a pipeline when README.md
is changed:
---
kind: pipeline
name: readme
trigger:
paths:
include:
- README.md
steps:
- name: message
image: busybox
commands:
- echo "README.md was changedβ
Only run a pipeline step when README.md
is changed:
---
kind: pipeline
name: readme
steps:
- name: message
image: busybox
commands:
- echo "README.md was changedβ
when:
paths:
include:
- README.md
Same as above, but with an implicit include
:
---
kind: pipeline
name: readme
steps:
- name: message
image: busybox
commands:
- echo "README.md was changedβ
when:
paths:
- README.md
include
and exclude
Run a pipeline step when .yml
files are changed in the root, except for .drone.yml
:
---
kind: pipeline
name: yaml
steps:
- name: message
image: busybox
commands:
- echo "A .yml file in the root of the repo other than .drone.yml was changed"
when:
paths:
include:
- "*.yml"
exclude:
- .drone.yml
depends_on
When using depends_on
in a pipeline step, ensure the paths
rules match, otherwise your steps may run out of order.
Only run two steps when README.md
is changed, one after the other:
---
kind: pipeline
name: depends_on
steps:
- name: message
image: busybox
commands:
- echo "README.md was changedβ
when:
paths:
include:
- README.md
- name: depends_on_message
depends_on:
- message
image: busybox
commands:
- echo "This step runs after the message step"
when:
paths:
include:
- README.md
Changesets
The changeset is generated by comparing the list of files changed between the commit before the patch is applied and the commit after the patch is applied. As a result, the changeset for a commit may be different depending on which type of event triggered the build.
For example, the push
and tag
events may generate a changeset against the previous commit, where as the pull_request
event may generate a changeset against the source branch. For more specifics on how before and after are set, review the webhook parser.
Known issues
Empty commits
Be careful when making empty commits with git commit --allow-empty
. When an empty commit is made, no files have changed, so this plugin will return the unmodified .drone.yml
back to the drone server process.
This can lead to potentially unexpected behavior, since any include
or exclude
rules will effectively be ignored.
YAML anchors
There is a problem in the YAML library where ordering matters during unmarshaling, see #18
This syntax will fail:
anchor: &anchor
image: busybox
settings:
foo: bar
- name: test
<<: *anchor
when:
event: push
branch: master
But this will succeed:
anchor: &anchor
image: busybox
settings:
foo: bar
- <<: *anchor
name: test
when:
event: push
branch: master

Please read CONTRIBUTING.md to understand how to submit pull requests to us, and also see our code of conduct.
Protected Repos
When this plugin is used in conjunction with protected repos, signature validation will frequently fail.
This occurs due to Drone's order of operations, in that the Drone file's signature is checked after the this plugin has rewritten sections based on the paths-changed triggers, resulting in a different signature for the file.
