 A GitHub action to create a pull request for changes to your repository in the actions workspace.

+Changes to a repository in the Actions workspace persist between steps in a workflow.

 The changes will be automatically committed to a new branch and a pull request created.

-2. Commit all changes to a new branch. The commit will be made using the name and email of the `HEAD` commit author.

 3. Create a pull request to merge the new branch into the currently active branch executing the workflow.
 
-Note: Modifying a repository during workflows is not good practice in general.

-#### Branch naming
+### Branch naming
 
-The variable `PULL_REQUEST_BRANCH` defaults to `create-pull-request/patch`.
+For branch naming there are two strategies. Always create a new branch each time there are changes to be committed, OR, create a fixed-name pull request branch that will be updated with any new commits until it is merged or closed.
-Commits will be made to a branch with this name and suffixed with the short SHA1 commit hash.
 
-e.g.
+#### Strategy A - Always create a new pull request branch (default)
-```
-create-pull-request/patch-fcdfb59
-create-pull-request/patch-394710b
-```
 
-Alternatively, branches can be suffixed with a timestamp by setting the environment variable `BRANCH_SUFFIX` to the value `timestamp`. This option may be necessary if multiple pull requests will be created during the execution of a workflow.
+For this strategy there are three options to suffix the branch name.
+The branch name is defined by the variable `PULL_REQUEST_BRANCH` and defaults to `create-pull-request/patch`. The following options are values for `BRANCH_SUFFIX`.
 
-e.g.
+- `short-commit-hash` (default) - Commits will be made to a branch suffixed with the short SHA1 commit hash. e.g. `create-pull-request/patch-fcdfb59`, `create-pull-request/patch-394710b`
-```
-create-pull-request/patch-1569322532
-create-pull-request/patch-1569322552
-```
 
-#### Ignoring files
+- `timestamp` - Commits will be made to a branch suffixed by a timestamp. e.g. `create-pull-request/patch-1569322532`, `create-pull-request/patch-1569322552`
+
+- `random` - Commits will be made to a branch suffixed with a random alpha-numeric string. This option should be used if multiple pull requests will be created during the execution of a workflow. e.g. `create-pull-request/patch-6qj97jr`, `create-pull-request/patch-5jrjhvd`
+
+#### Strategy B - Create and update a pull request branch
+
+To use this strategy, set `BRANCH_SUFFIX` to the value `none`. The variable `PULL_REQUEST_BRANCH` defaults to `create-pull-request/patch`. Commits will be made to this branch and a pull request created. Any subsequent changes will be committed to the *same* branch and reflected in the existing pull request.
+
+### Ignoring files
 
 If there are files or directories you want to ignore you can simply add them to a `.gitignore` file at the root of your repository. The action will respect this file.
 
-## Example
+## Examples
 
 Here is an example that sets all the main environment variables.
 
 ```yml
-    - name: Create Pull Request
+on:
-      uses: peter-evans/create-pull-request@v1.2.1
+  repository_dispatch:
-      env:

-        PULL_REQUEST_TITLE: Changes from my-file-modifier-action
+    steps:
-        PULL_REQUEST_BODY: This is an auto-generated PR with changes from my-file-modifier-action
+      - uses: actions/checkout@v1
+      - name: Create report file

+          PULL_REQUEST_TITLE: '[Example] Add report file'
+          PULL_REQUEST_BODY: >
+            This PR is auto-generated by 
+            [create-pull-request](https://github.com/peter-evans/create-pull-request).
+          PULL_REQUEST_LABELS: report, automated pr
+          PULL_REQUEST_ASSIGNEES: peter-evans
+          PULL_REQUEST_REVIEWERS: peter-evans
+          PULL_REQUEST_MILESTONE: 1
+          PULL_REQUEST_BRANCH: example-patches
+          BRANCH_SUFFIX: short-commit-hash
+      - name: Check output environment variable
+        run: echo "Pull Request Number - $PULL_REQUEST_NUMBER"
 ```
 
 This configuration will create pull requests that look like this:
 
-![Pull Request Example](pull-request-example.png?raw=true)
+![Pull Request Example](https://github.com/peter-evans/create-pull-request/blob/master/pull-request-example.png?raw=true)
+
+### Dynamic configuration using variables
+
+The following examples show how configuration for the action can be dynamically defined in a previous workflow step.
+
+The recommended method is to use `set-output`. Note that the step where output variables are defined must have an id.
+
+```yml
+      - name: Set output variables
+        id: vars
+        run: |
+          echo ::set-output name=pr_title::"[Test] Add report file $(date +%d-%m-%Y)"
+          echo ::set-output name=pr_body::"This PR was auto-generated on $(date +%d-%m-%Y) \
+            by [create-pull-request](https://github.com/peter-evans/create-pull-request)."
+      - name: Create Pull Request
+        uses: peter-evans/create-pull-request@v1.5.1
+        env:
+          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
+          PULL_REQUEST_TITLE: ${{ steps.vars.outputs.pr_title }}
+          PULL_REQUEST_BODY: ${{ steps.vars.outputs.pr_body }}
+```
+
+Since the action reads environment variables from the system, it's technically not necessary to explicitly pass them as long as they exist in the environment. So the following method using `set-env` *also* works, but explicitly passing the configuration parameters using the previous method is perferred for its clarity.
+
+```yml
+      - name: Set environment variables
+        run: |
+          echo ::set-env name=PULL_REQUEST_TITLE::"[Test] Add report file $(date +%d-%m-%Y)"
+          echo ::set-env name=PULL_REQUEST_BODY::"This PR was auto-generated on $(date +%d-%m-%Y) \
+            by [create-pull-request](https://github.com/peter-evans/create-pull-request)."
+      - name: Create Pull Request
+        uses: peter-evans/create-pull-request@v1.5.1
+        env:
+          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
+```
