GitHub API supports these types of comments:
- Comments on Repos/Commits
- Comments on Pull Request Reviews
- Comments on Pull Request Files
- Comments on Issues
- Comments on Pull Requests (in the global section)
Since GitHub considers Pull Requests as Issues, Comments on Issues
and Comments on Pull Requests
use the same API.
The utility supports all these types of comments (commit
, pr-review
, pr-file
, issue
, pr
).
This project is part of our comprehensive "SweetOps" approach towards DevOps. <img align="right" title="Share via Email" src="https://docs.cloudposse.com/images/ionicons/ios-email-outline-2.0.1-16x16-999999.svg"/> <img align="right" title="Share on Google+" src="https://docs.cloudposse.com/images/ionicons/social-googleplus-outline-2.0.1-16x16-999999.svg" /> <img align="right" title="Share on Facebook" src="https://docs.cloudposse.com/images/ionicons/social-facebook-outline-2.0.1-16x16-999999.svg" /> <img align="right" title="Share on Reddit" src="https://docs.cloudposse.com/images/ionicons/social-reddit-outline-2.0.1-16x16-999999.svg" /> <img align="right" title="Share on LinkedIn" src="https://docs.cloudposse.com/images/ionicons/social-linkedin-outline-2.0.1-16x16-999999.svg" /> <img align="right" title="Share on Twitter" src="https://docs.cloudposse.com/images/ionicons/social-twitter-outline-2.0.1-16x16-999999.svg" />

GitHub PR Review Comment
Usage
NOTE: Create a GitHub token with repo:status
and public_repo
scopes.
NOTE: The utility accepts parameters as command-line arguments or as ENV variables (or any combination of command-line arguments and ENV vars). Command-line arguments take precedence over ENV vars.
Command-line argument | ENV var | Description |
---|---|---|
token | GITHUB_TOKEN | Github access token |
owner | GITHUB_OWNER | Github repository owner (e.g. cloudposse ) |
repo | GITHUB_REPO | Github repository name (e.g. github-commenter ) |
type | GITHUB_COMMENT_TYPE | Comment type: commit , pr , issue , pr-review or pr-file |
sha | GITHUB_COMMIT_SHA | Commit SHA. Required when type=commit or type=pr-file |
number | GITHUB_PR_ISSUE_NUMBER | Pull Request or Issue number. Required for all comment types except for commit |
file | GITHUB_PR_FILE | Pull Request File Name to comment on. For more info see create comment |
position | GITHUB_PR_FILE_POSITION | Position in Pull Request File. For more info see create comment |
template | GITHUB_COMMENT_TEMPLATE | Template to format comment (optional). Supports Go templates. E.g. My comment:<br/>{{.}} . Use either template or template_file |
template_file | GITHUB_COMMENT_TEMPLATE_FILE | The path to a template file to format comment (optional). Supports Go templates. Use either template or template_file |
format | GITHUB_COMMENT_FORMAT | Alias of template |
format_file | GITHUB_COMMENT_FORMAT_FILE | Alias of template_file |
comment | GITHUB_COMMENT | Comment text. If neither comment nor GITHUB_COMMENT provided, will read from stdin |
delete-comment-regex | GITHUB_DELETE_COMMENT_REGEX | Regex to find previous comments to delete before creating the new comment. Supported for comment types commit , pr-file , issue and pr |
edit-comment-regex | GITHUB_EDIT_COMMENT_REGEX | Regex to find previous comments to replace with new content, or create new comment if none found. Supported for comment types commit , pr-file , issue and pr |
baseURL | GITHUB_BASE_URL | Github Enterprise URL. E.g. https://github.example.com/api/v3 |
uploadURL | GITHUB_UPLOAD_URL | Github Enterprise Upload URL to pass to the Github client |
insecure | GITHUB_INSECURE | Boolean to ignore SSL certificate check |
NOTE: The utility accepts the text of the comment from the command-line argument comment
, from the ENV variable GITHUB_COMMENT
, or from the standard input.
Command-line argument takes precedence over ENV var, and ENV var takes precedence over standard input.
Accepting comments from stdin
allows using Unix pipes to send the output from another program as the input to the tool:
cat comment.txt | github-commenter ...
terraform plan 2>&1 | github-commenter -format "Output from `terraform plan`<br/>```{{.}}```"
NOTE: The utility supports sprig functions in Go
templates, allowing to use string replacement and Regular Expressions in the format
argument.
See string functions for more details.
For example:
GITHUB_COMMENT_FORMAT="Helm diff:<br><br><pre>{{regexReplaceAllLiteral `\\n` . `<br>` }}<pre>"
Examples
The utility can be called directly or as a Docker container.
Build the Go program locally
go get
CGO_ENABLED=0 go build -v -o "./dist/bin/github-commenter" *.go
Run locally with ENV vars
export GITHUB_TOKEN=XXXXXXXXXXXXXXXX
export GITHUB_OWNER=cloudposse
export GITHUB_REPO=github-commenter
export GITHUB_COMMENT_TYPE=pr
export GITHUB_PR_ISSUE_NUMBER=1
export GITHUB_COMMENT_FORMAT="My comment:<br/>{{.}}"
export GITHUB_COMMENT="+1 LGTM"
./dist/bin/github-commenter
Run locally with command-line arguments
run_locally_with_command_line_args.sh
./dist/bin/github-commenter \
-token XXXXXXXXXXXXXXXX \
-owner cloudposse \
-repo github-commenter \
-type pr \
-number 1 \
-format "My comment:<br/>{{.}}" \
-comment "+1 LGTM"
Build the Docker image
NOTE: it will download all Go
dependencies and then build the program inside the container (see Dockerfile
)
docker build --tag github-commenter --no-cache=true .
Run in a Docker container with ENV vars
docker run -i --rm \
-e GITHUB_TOKEN=XXXXXXXXXXXXXXXX \
-e GITHUB_OWNER=cloudposse \
-e GITHUB_REPO=github-commenter \
-e GITHUB_COMMENT_TYPE=pr \
-e GITHUB_PR_ISSUE_NUMBER=1 \
-e GITHUB_COMMENT_FORMAT="My comment:<br/>{{.}}" \
-e GITHUB_COMMENT="+1 LGTM" \
github-commenter
Run with Docker
Run github-commenter
in a Docker container with local ENV vars propagated into the container's environment.
run_docker_with_local_env_vars.sh
export GITHUB_TOKEN=XXXXXXXXXXXXXXXX
export GITHUB_OWNER=cloudposse
export GITHUB_REPO=github-commenter
export GITHUB_COMMENT_TYPE=pr
export GITHUB_PR_ISSUE_NUMBER=1
export GITHUB_COMMENT_FORMAT="Helm diff:<br><br><pre>{{regexReplaceAllLiteral `\\n` . `<br>` }}<pre>"
export GITHUB_COMMENT="Helm diff comment"
docker run -i --rm \
-e GITHUB_TOKEN \
-e GITHUB_OWNER \
-e GITHUB_REPO \
-e GITHUB_COMMENT_TYPE \
-e GITHUB_PR_ISSUE_NUMBER \
-e GITHUB_COMMENT_FORMAT \
-e GITHUB_COMMENT \
github-commenter
Run with Docker using Env File
Run the github-commenter
in a Docker container with ENV vars declared in a file.
run_docker_with_env_vars_file.sh
docker run -i --rm --env-file ./example.env github-commenter
delete-comment-regex
example 1
Delete all previous comments on Pull Request #2 that contain the string test1
in the body of the comments and create a new PR comment
./dist/bin/github-commenter \
-token XXXXXXXXXXXXXXXX \
-owner cloudposse \
-repo github-commenter \
-type pr \
-number 2 \
-format "{{.}}" \
-delete-comment-regex "test1" \
-comment "New Pull Request comment"
delete-comment-regex
example 2
Delete all previous comments on Issue #1 that contain the string test2
at the end of the comment's body and create a new Issue comment
./dist/bin/github-commenter \
-token XXXXXXXXXXXXXXXX \
-owner cloudposse \
-repo github-commenter \
-type issue \
-number 1 \
-format "{{.}}" \
-delete-comment-regex "test2$" \
-comment "New Issue comment"
delete-comment-regex
example 3
Delete all previous commit comments that contain the string test3
in the body and create a new commit comment
./dist/bin/github-commenter \
-token XXXXXXXXXXXXXXXX \
-owner cloudposse \
-repo github-commenter \
-type commit \
-sha xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx \
-format "{{.}}" \
-delete-comment-regex "test3" \
-comment "New commit comment"
delete-comment-regex
example 4
Delete all previous comments on a Pull Request file doc.txt
that contain the string test4
in the body of the comments and create a new comment on the file
./dist/bin/github-commenter \
-token XXXXXXXXXXXXXXXX \
-owner cloudposse \
-repo github-commenter \
-type pr-file \
-sha xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx \
-number 2 \
-file doc.txt \
-position 1 \
-format "{{.}}" \
-delete-comment-regex "test4" \
-comment "New comment on the PR file"
edit-comment-regex
The -edit-comment-regex
flag operates similarly to the -delete-comment-regex
except existing comments will be updated instead of deleted. If no matching comment is found a new comment is created.
