# danger-gitlab_graph
-A description of danger-gitlab_graph.
+`danger-gitlab_graph` is a [Danger](https://danger.systems) ruby plugin that allows you to extract and display metrics
+gathered from the current and previous pipeline runs. This plugin is only works with GitLab CI at the moment.
+It works similar to the existing test coverage extraction provided by GitLab natively: You provide a job name, an
+extraction regex (including a single capturing group) and some other, optional configuration options. The plugin then
+creates an svg graph (using the [svg-graph2](https://github.com/lumean/svg-graph2) gem) and adds them to your other
+Danger comments.
+
## Installation
$ gem install danger-gitlab_graph
## Usage
Methods and attributes from this plugin are available in
your `Dangerfile` under the `gitlab_graph` namespace.
+
+### Methods
+
+`gather_metric` - Gathers metric data from current and pevious pipelines
+
+Sample code:
+
+```ruby
+@my_plugin.gather_metric({
+ regex: /took ([0-9]+)/,
+ series_name: "Performance",
+ job_name: "test1"
+ })
+```
+
+returns an array similiar to this:
+
+```ruby
+[{ hash: "b23f54ecdc3add9abea9344f66b49f1699bff547", metric: 16.0, pipeline_id: 1119 },
+ { hash: "3333333333333333333333333333333333333333", metric: 6.0, pipeline_id: 123_456 }]
+```
+
+`report_metric` - Creates and comments a graph based on a certain metric, extracted via regex
+
+Sample code
+
+```ruby
+gitlab_graph.report_metric([{
+ regex: /took ([0-9]+)/,
+ series_name: "Performance",
+ job_name: "test1"
+ }, {
+ regex: /slept ([0-9]+)/,
+ series_name: "IDLE time",
+ job_name: "test1"
+ }]) < /pre>
+```
+
+outputs a graph similiar to this
+
+![sample graph](spec/support/fixtures/graph-simple-expected.svg)
+
+and writes it directly into the danger comment
