## What is Reviewpad?
Reviewpad is a service to automate pull requests and issues workflows.
The workflows are specified in a YML-based configuration language described in the [official documentation](https://docs.reviewpad.com/guides/syntax).
In Reviewpad, you can automate actions over the pull requests and issues such as:
1. Automated [comments](https://docs.reviewpad.com/use-cases/comment-on-pull-requests);
2. Add or remove [labels](https://docs.reviewpad.com/use-cases/automated-labelling/);
3. Specify [reviewer assignments](https://docs.reviewpad.com/use-cases/reviewer-assignment);
4. Automate [close/merge actions](https://docs.reviewpad.com/use-cases/auto-merge);
5. [Block the merge action](https://docs.reviewpad.com/use-cases/blocking-merge);
6. Automatically [summarize pull requests](https://docs.reviewpad.com/guides/built-ins#summarize);
As an example, the following workflow:
```yml
labels:
ship:
description: Ship mode
color: "#76dbbe"
workflows:
- name: ship
description: Ship process - bypass the review and merge with rebase
run:
- if: $hasFileExtensions([".md"])
then:
- $addLabel("ship")
- $merge()
```
Automatically adds the label `ship` and merges all pull requests that only change `.md` files.
You can execute Reviewpad through the CLI or install Reviewpad [GitHub App](https://github.com/marketplace/reviewpad).
## Architecture
This repository generates two artifacts:
1. CLI [cli](cli/main.go) that runs Reviewpad open source edition.
2. Reviewpad library packages:
- github.com/reviewpad/reviewpad/collector
- github.com/reviewpad/reviewpad/engine
- github.com/reviewpad/reviewpad/lang/aladino
- github.com/reviewpad/reviewpad/plugins/aladino
- github.com/reviewpad/reviewpad/utils
Conceptually, the packages are divided into four categories:
1. Engine: The engine is the package responsible for processing the YML file. This process is divided into two stages:
- Process the YML file to determine which workflows are enabled. The outcome of this phase is a program with the actions that will be executed over the pull request.
- Execution of the synthesised program.
2. [Aladino Language](https://docs.reviewpad.com/guides/aladino-language): This is the language that is used in the `spec` property of the rules and also the actions of the workflows. The engine of Reviewpad is not specific to Aladino - this means that it is possible to add support for a new language such as `Javascript` or `Golang` in these specifications.
3. Plugins: The plugin package contains the built-in functions and actions that act as an abstraction to the 3rd party services such as GitHub, Jira, etc. This package is specific to each supported specification language. In the case of `plugins/aladino`, it contains the implementations of the [built-ins](https://docs.reviewpad.com/guides/built-ins).
4. Utilities: packages, such as the collector, that provide utilities that are used in multiple places.
## Development
### Prerequisites
Before you begin, ensure you have met the following requirements:
- [Go](https://golang.org/doc/install) with the minimum version of 1.16.
- [goyacc](https://pkg.go.dev/golang.org/x/tools/cmd/goyacc) used to generate Reviewpad Aladino parser (`go install golang.org/x/tools/cmd/goyacc@master`).
- [libgit2](https://github.com/libgit2/libgit2) with version v1.2.
- To run the tests, Reviewpad requires the following environment variables:
- `INPUT_SEMANTIC_SERVICE`. You can do this by running the following command in your terminal: `export INPUT_SEMANTIC_SERVICE="0.0.0.0:3006"`.
- `INPUT_ROBIN_SERVICE`. You can do this by running the following command in your terminal: `export INPUT_ROBIN_SERVICE="0.0.0.0:3011"`.
- `INPUT_CODEHOST_SERVICE`. You can do this by running the following command in your terminal: `export INPUT_CODEHOST_SERVICE="0.0.0.0:3004"`.
### Compilation
We use [Taskfile](https://taskfile.dev/). To compile the packages simply run:
```sh
task build
```
To generate the CLI run:
```sh
task build-cli
```
This command generates the binary `reviewpad-cli` which you can run to try Reviewpad directly.
The CLI has the following argument list:
```sh
./reviewpad-cli
reviewpad-cli is command line interface to run reviewpad commands.
Usage:
reviewpad-cli [command]
Available Commands:
check Check if input reviewpad file is valid
completion Generate the autocompletion script for the specified shell
help Help about any command
run Runs reviewpad
Flags:
-f, --file string input reviewpad file
-h, --help help for reviewpad-cli
Use "reviewpad-cli [command] --help" for more information about a command.
```
### Running unit tests
Run the tests with:
```
task test
```
If you get the error:
```
panic: httptest: failed to listen on a port: listen tcp6 [::1]:0: socket: too many open files [recovered]
panic: httptest: failed to listen on a port: listen tcp6 [::1]:0: socket: too many open files
```
You can solve with:
```
ulimit -Sn 500
```
#### Coverage
To generate the coverage report run:
```
task test
```
To display the code coverage for every package run:
```
go tool cover -func coverage.out
```
To display the total code coverage percentage run:
```
go tool cover -func coverage.out | grep total:
```
### Running integration tests
The integration tests run Reviewpad on an actual repository and pull request. The repository where the integration tests run requires the following setup:
- At least one milestone;
- At least 3 labels named `bug`, `documentation`, `wontfix` (GitHub adds these labels to every new repository by default);
- A team called `integration-test` with at least 3 members;
- A project called `[INTEGRATION TESTS] Reviewpad` with `Todo` and `In Progress` status
- A GitHub status check called `log event`.
#### Required Environment Variables
- `GITHUB_INTEGRATION_TEST_TOKEN` : GitHub access token used to setup tests and run Reviewpad
- `GITHUB_INTEGRATION_TEST_REPO_OWNER` : The owner of the repository used to run integration tests on
- `GITHUB_INTEGRATION_TEST_REPO_NAME` : The name of the repository used to run integration tests on
After setting these variables, you can run the integration tests with:
```
task integration-test
```

#### How to get the GitHub event body (internal use only)
The `-e` flag is mandatory to run the debugger.
It represents the GitHub event that you wish to run the reviewpad.yml file against.
To extract a GitHub event, please follow the steps below:
1. Navigate to the GitHub URL of the pull request you want to test against.
2. Click on the `reviewpad` check under the `Checks` tab.
3. From the `DETAILS` section of the check copy the `Delivery ID`.
4. Go to the logs of the Entry Gate and filter out the logs using the query `{$.delivery_id="[Delivery ID]" && $.msg="request received"}`
5. Copy the content inside the `body` field.
6. Create a file under `cli > debugdata` with a name that ends with `.json` (e.g. `my_event.json`) and paste the content inside the file.
7. This content is an escape JSON string. Use the [JSON Parse & Stringify](https://marketplace.visualstudio.com/items?itemName=nextfaze.json-parse-stringify) extension to parse the content by pressing `Ctrl+Shift+P` and searching for `JSON: Parse Stringified JSON`.
8. Update the argument `-e` to point to the full path of the file you just created.
#### How to get the GitHub event type (internal use only)
The `-y` flag is mandatory to run the debugger.
It represents the type of GitHub event that you wish to run the reviewpad.yml file against.
To get the GitHub event type, please follow the steps below:
1. Navigate to the GitHub URL of the pull request you want to test against.
2. Click on the `reviewpad` check under the `Checks` tab.
3. From the `DETAILS` section of the check copy the `Event Type`.
4. Paste the content inside the `-y` flag.
If you wish to use the logs of the Entry Gate to the event type, please follow the steps below:
1. Filter out the logs using the query `{$.delivery_id="[Delivery ID]" && $.msg="request received"}`
2. Copy the content inside the `headers.X-GitHub-Event` field.
