# Contributing
Prometheus uses GitHub to manage reviews of pull requests.
* If you have a trivial fix or improvement, go ahead and create a pull request,
addressing (with `@...`) the maintainer of this repository (see
[MAINTAINERS.md](MAINTAINERS.md)) in the description of the pull request.
* If you plan to do something more involved, first discuss your ideas
on our [mailing list](https://groups.google.com/forum/?fromgroups#!forum/prometheus-developers).
This will avoid unnecessary work and surely give you and us a good deal
of inspiration.
* Relevant coding style guidelines are the [Go Code Review
Comments](https://code.google.com/p/go-wiki/wiki/CodeReviewComments)
and the _Formatting and style_ section of Peter Bourgon's [Go: Best
Practices for Production
Environments](http://peter.bourgon.org/go-in-production/#formatting-and-style).

# Common
[![Build Status](https://travis-ci.org/prometheus/common.svg)](https://travis-ci.org/prometheus/common)
This repository contains Go libraries that are shared across Prometheus
components and libraries.
* **config**: Common configuration structures
* **expfmt**: Decoding and encoding for the exposition format
* **log**: A logging wrapper around [logrus](https://github.com/sirupsen/logrus)
* **model**: Shared data structures
* **route**: A routing wrapper around [httprouter](https://github.com/julienschmidt/httprouter) using `context.Context`
* **version**: Version information and metrics

// MetricFamilyToOpenMetrics converts a MetricFamily proto message into the
// OpenMetrics text format and writes the resulting lines to 'out'. It returns
// the number of bytes written and any error encountered. The output will have
// the same order as the input, no further sorting is performed. Furthermore,
// this function assumes the input is already sanitized and does not perform any
// sanity checks. If the input contains duplicate metrics or invalid metric or
// label names, the conversion will result in invalid text format output.
//
// This function fulfills the type 'expfmt.encoder'.
//
// Note that OpenMetrics requires a final `# EOF` line. Since this function acts
// on individual metric families, it is the responsibility of the caller to
// append this line to 'out' once all metric families have been written.
// Conveniently, this can be done by calling FinalizeOpenMetrics.
//
// The output should be fully OpenMetrics compliant. However, there are a few
// missing features and peculiarities to avoid complications when switching from
// Prometheus to OpenMetrics or vice versa:
//
// - Counters are expected to have the `_total` suffix in their metric name. In
// the output, the suffix will be truncated from the `# TYPE` and `# HELP`
// line. A counter with a missing `_total` suffix is not an error. However,
// its type will be set to `unknown` in that case to avoid invalid OpenMetrics
// output.
//
// - No support for the following (optional) features: `# UNIT` line, `_created`
// line, info type, stateset type, gaugehistogram type.
//
// - The size of exemplar labels is not checked (i.e. it's possible to create
// exemplars that are larger than allowed by the OpenMetrics specification).
//
// - The value of Counters is not checked. (OpenMetrics doesn't allow counters
// with a `NaN` value.)
