# go-nmea [![Build Status](https://travis-ci.org/adrianmo/go-nmea.svg?branch=master)](https://travis-ci.org/adrianmo/go-nmea) [![Go Report Card](https://goreportcard.com/badge/github.com/adrianmo/go-nmea)](https://goreportcard.com/report/github.com/adrianmo/go-nmea) [![Coverage Status](https://coveralls.io/repos/adrianmo/go-nmea/badge.svg?branch=master&service=github)](https://coveralls.io/github/adrianmo/go-nmea?branch=master) [![GoDoc](https://godoc.org/github.com/adrianmo/go-nmea?status.svg)](https://godoc.org/github.com/adrianmo/go-nmea)
This is a NMEA library for the Go programming language (http://golang.org).
## Installing
### Using `go get`
go get github.com/adrianmo/go-nmea
After this command *go-nmea* is ready to use. Its source will be in:
$GOPATH/src/github.com/adrianmo/go-nmea
## Supported sentences
At this moment, this library supports the following sentence types:
- [GPRMC](http://aprs.gids.nl/nmea/#rmc) - Recommended Minimum Specific GPS/Transit data
- [GNRMC](http://aprs.gids.nl/nmea/#rmc) - Recommended Minimum Specific GNSS data
- [GPGGA](http://aprs.gids.nl/nmea/#gga) - GPS Positioning System Fix Data
- [GNGGA](http://aprs.gids.nl/nmea/#gga) - GNSS Positioning System Fix Data
- [GPGSA](http://aprs.gids.nl/nmea/#gsa) - GPS DOP and active satellites
- [GPGSV](http://aprs.gids.nl/nmea/#gsv) - GPS Satellites in view
- [GLGSV](http://aprs.gids.nl/nmea/#gsv) - GLONASS Satellites in view
- [GPGLL](http://aprs.gids.nl/nmea/#gll) - Geographic Position, Latitude / Longitude and time
- [GPVTG](http://aprs.gids.nl/nmea/#vtg) - Track Made Good and Ground Speed
- [GPZDA](http://aprs.gids.nl/nmea/#zda) - Date & time data
- [PGRME](http://aprs.gids.nl/nmea/#rme) - Estimated Position Error (Garmin proprietary sentence)
- [GPHDT](http://aprs.gids.nl/nmea/#hdt) - Actual vessel heading in degrees True
## Example
```go
package main
import (
"fmt"
"log"
"github.com/adrianmo/go-nmea"
)
func main() {
sentence := "$GPRMC,220516,A,5133.82,N,00042.24,W,173.8,231.8,130694,004.2,W*70"
s, err := nmea.Parse(sentence)
if err != nil {
log.Fatal(err)
}
m := s.(nmea.GPRMC)
fmt.Printf("Raw sentence: %v\n", m)
fmt.Printf("Time: %s\n", m.Time)
fmt.Printf("Validity: %s\n", m.Validity)
fmt.Printf("Latitude GPS: %s\n", nmea.FormatGPS(m.Latitude))
fmt.Printf("Latitude DMS: %s\n", nmea.FormatDMS(m.Latitude))
fmt.Printf("Longitude GPS: %s\n", nmea.FormatGPS(m.Longitude))
fmt.Printf("Longitude DMS: %s\n", nmea.FormatDMS(m.Longitude))
fmt.Printf("Speed: %f\n", m.Speed)
fmt.Printf("Course: %f\n", m.Course)
fmt.Printf("Date: %s\n", m.Date)
fmt.Printf("Variation: %f\n", m.Variation)
}
```
Output:
```
$ go run main/main.go
Raw sentence: $GPRMC,220516,A,5133.82,N,00042.24,W,173.8,231.8,130694,004.2,W*70
Time: 22:05:16.0000
Validity: A
Latitude GPS: 5133.8200
Latitude DMS: 51° 33' 49.200000"
Longitude GPS: 042.2400
Longitude DMS: 0° 42' 14.400000"
Speed: 173.800000
Course: 231.800000
Date: 13/06/94
Variation: -4.200000
```
## Contributions
Please, feel free to implement support for new sentences, fix bugs, refactor code, etc. and send a pull-request to update the library.

[![Go Report Card](https://goreportcard.com/badge/github.com/antchfx/jsonquery)](https://goreportcard.com/report/github.com/antchfx/jsonquery)
Overview
===
jsonquery is an XPath query package for JSON document, lets you extract data from JSON documents through an XPath expression.
Getting Started
===
### Install Package
> $ go get github.com/antchfx/jsonquery
#### Load JSON document from URL.
```go
doc, err := jsonquery.LoadURL("http://www.example.com/feed?json")
```
#### Load JSON document from string.
```go
s :=`{
"name":"John",
"age":31,
"city":"New York"
}`
doc, err := jsonquery.Parse(strings.NewReader(s))
```
#### Load JSON document from io.Reader.
```go
f, err := os.Open("./books.json")
doc, err := jsonquery.Parse(f)
```
#### Find authors of all books in the store.
```go
list := jsonquery.Find(doc, "store/book/*/author")
// or equal to
list := jsonquery.Find(doc, "//author")
```
#### Find the third book.
```go
book := jsonquery.Find(doc, "//book/*[3]")
```
#### Find the last book.
```go
book := jsonquery.Find(doc, "//book/*[last()]")
```
#### Find all books with isbn number.
```go
list := jsonquery.Find(doc, "//book/*[isbn]")
```
#### Find all books cheapier than 10.
```go
list := jsonquery.Find(doc, "//book/*[price<10]")
```
Quick Tutorial
===
```go
func main() {
s := `{
"name": "John",
"age" : 26,
"address" : {
"streetAddress": "naist street",
"city" : "Nara",
"postalCode" : "630-0192"
},
"phoneNumbers": [
{
"type" : "iPhone",
"number": "0123-4567-8888"
},
{
"type" : "home",
"number": "0123-4567-8910"
}
]
}`
doc, _ := jsonquery.Parse(strings.NewReader(s))
name := jsonquery.FindOne(doc, "name")
fmt.Printf("name: %s\n", name.InnerText())
var a []string
for _, n := range jsonquery.Find(doc, "phoneNumbers/*/number") {
a = append(a, n.InnerText())
}
fmt.Printf("phone number: %s\n", strings.Join(a, ","))
if n := jsonquery.FindOne(doc, "address/streetAddress"); n != nil {
fmt.Printf("address: %s\n", n.InnerText())
}
}
```
Implement Principle
===
If you are familiar with XPath and XML, you can quick start to known how
write your XPath expression.
```json
{
"name":"John",
"age":30,
"cars": [
{ "name":"Ford", "models":[ "Fiesta", "Focus", "Mustang" ] },
{ "name":"BMW", "models":[ "320", "X3", "X5" ] },
{ "name":"Fiat", "models":[ "500", "Panda" ] }
]
}
```
The above JSON document will be convert to similar to XML document by the *JSONQuery*, like below:
```XML
<name>John</name>
<age>30</age>
<cars>
<element>
<name>Ford</name>
<models>
<element>Fiesta</element>
<element>Focus</element>
<element>Mustang</element>
</models>
</element>
<element>
<name>BMW</name>
<models>
<element>320</element>
<element>X3</element>
<element>X5</element>
</models>
</element>
<element>
<name>Fiat</name>
<models>
<element>500</element>
<element>Panda</element>
</models>
</element>
</cars>
```
Notes: `element` is empty element that have no any name.

XPath
====
[![GoDoc](https://godoc.org/github.com/antchfx/xpath?status.svg)](https://godoc.org/github.com/antchfx/xpath)
[![Coverage Status](https://coveralls.io/repos/github/antchfx/xpath/badge.svg?branch=master)](https://coveralls.io/github/antchfx/xpath?branch=master)
[![Build Status](https://travis-ci.org/antchfx/xpath.svg?branch=master)](https://travis-ci.org/antchfx/xpath)
[![Go Report Card](https://goreportcard.com/badge/github.com/antchfx/xpath)](https://goreportcard.com/report/github.com/antchfx/xpath)
XPath is Go package provides selecting nodes from XML, HTML or other documents using XPath expression.
Implementation
===
- [htmlquery](https://github.com/antchfx/htmlquery) - an XPath query package for HTML document
- [xmlquery](https://github.com/antchfx/xmlquery) - an XPath query package for XML document.
- [jsonquery](https://github.com/antchfx/jsonquery) - an XPath query package for JSON document
Supported Features
===
#### The basic XPath patterns.
> The basic XPath patterns cover 90% of the cases that most stylesheets will need.
- `node` : Selects all child elements with nodeName of node.
- `*` : Selects all child elements.
- `@attr` : Selects the attribute attr.
- `@*` : Selects all attributes.
- `node()` : Matches an org.w3c.dom.Node.
- `text()` : Matches a org.w3c.dom.Text node.
- `comment()` : Matches a comment.
- `.` : Selects the current node.
- `..` : Selects the parent of current node.
- `/` : Selects the document node.
- `a[expr]` : Select only those nodes matching a which also satisfy the expression expr.
- `a[n]` : Selects the nth matching node matching a When a filter's expression is a number, XPath selects based on position.
- `a/b` : For each node matching a, add the nodes matching b to the result.
- `a//b` : For each node matching a, add the descendant nodes matching b to the result.
- `//b` : Returns elements in the entire document matching b.
- `a|b` : All nodes matching a or b, union operation(not boolean or).
- `(a, b, c)` : Evaluates each of its operands and concatenates the resulting sequences, in order, into a single result sequence
#### Node Axes
- `child::*` : The child axis selects children of the current node.
- `descendant::*` : The descendant axis selects descendants of the current node. It is equivalent to '//'.
- `descendant-or-self::*` : Selects descendants including the current node.
- `attribute::*` : Selects attributes of the current element. It is equivalent to @*
- `following-sibling::*` : Selects nodes after the current node.
- `preceding-sibling::*` : Selects nodes before the current node.
- `following::*` : Selects the first matching node following in document order, excluding descendants.
- `preceding::*` : Selects the first matching node preceding in document order, excluding ancestors.
- `parent::*` : Selects the parent if it matches. The '..' pattern from the core is equivalent to 'parent::node()'.
- `ancestor::*` : Selects matching ancestors.
- `ancestor-or-self::*` : Selects ancestors including the current node.
- `self::*` : Selects the current node. '.' is equivalent to 'self::node()'.
#### Expressions
The gxpath supported three types: number, boolean, string.
- `path` : Selects nodes based on the path.
- `a = b` : Standard comparisons.
* a = b True if a equals b.
* a != b True if a is not equal to b.
* a < b True if a is less than b.
* a <= b True if a is less than or equal to b.
* a > b True if a is greater than b.
* a >= b True if a is greater than or equal to b.
- `a + b` : Arithmetic expressions.
* `- a` Unary minus
* a + b Add
* a - b Substract
* a * b Multiply
* a div b Divide
* a mod b Floating point mod, like Java.
- `a or b` : Boolean `or` operation.
- `a and b` : Boolean `and` operation.
- `(expr)` : Parenthesized expressions.
- `fun(arg1, ..., argn)` : Function calls:

// Package gatt provides a Bluetooth Low Energy gatt implementation.
//
// Gatt (Generic Attribute Profile) is the protocol used to write
// BLE peripherals (servers) and centrals (clients).
//
// STATUS
//
// This package is a work in progress. The API will change.
//
// As a peripheral, you can create services, characteristics, and descriptors,
// advertise, accept connections, and handle requests.
// As a central, you can scan, connect, discover services, and make requests.
//
// SETUP
//
// gatt supports both Linux and OS X.
//
// On Linux:
// To gain complete and exclusive control of the HCI device, gatt uses
// HCI_CHANNEL_USER (introduced in Linux v3.14) instead of HCI_CHANNEL_RAW.
// Those who must use an older kernel may patch in these relevant commits
// from Marcel Holtmann:
//
// Bluetooth: Introduce new HCI socket channel for user operation
// Bluetooth: Introduce user channel flag for HCI devices
// Bluetooth: Refactor raw socket filter into more readable code
//
// Note that because gatt uses HCI_CHANNEL_USER, once gatt has opened the
// device no other program may access it.
//
// Before starting a gatt program, make sure that your BLE device is down:
//
// sudo hciconfig
// sudo hciconfig hci0 down # or whatever hci device you want to use
//
// If you have BlueZ 5.14+ (or aren't sure), stop the built-in
// bluetooth server, which interferes with gatt, e.g.:
//
// sudo service bluetooth stop
//
// Because gatt programs administer network devices, they must
// either be run as root, or be granted appropriate capabilities:
//
// sudo <executable>
// # OR
// sudo setcap 'cap_net_raw,cap_net_admin=eip' <executable>
// <executable>
//
// USAGE
//
// # Start a simple server.
// sudo go run example/server.go
//
// # Discover surrounding peripherals.
// sudo go run example/discoverer.go
//
// # Connect to and explorer a peripheral device.
// sudo go run example/explorer.go <peripheral ID>
//
// See the server.go, discoverer.go, and explorer.go in the examples/
// directory for writing server or client programs that run on Linux
// and OS X.
//
// Users, especially on Linux platforms, seeking finer-grained control
// over the devices can see the examples/server_lnx.go for the usage
// of Option, which are platform specific.
//
// See the rest of the docs for other options and finer-grained control.
//
// Note that some BLE central devices, particularly iOS, may aggressively
// cache results from previous connections. If you change your services or
// characteristics, you may need to reboot the other device to pick up the
// changes. This is a common source of confusion and apparent bugs. For an
// OS X central, see http://stackoverflow.com/questions/20553957.
//
//
// REFERENCES
//
// gatt started life as a port of bleno, to which it is indebted:
// https://github.com/sandeepmistry/bleno. If you are having
// problems with gatt, particularly around installation, issues
// filed with bleno might also be helpful references.
//
// To try out your GATT server, it is useful to experiment with a
// generic BLE client. LightBlue is a good choice. It is available
// free for both iOS and OS X.

# Package gatt provides a Bluetooth Low Energy GATT implementation.
Gatt (Generic Attribute Profile) is the protocol used to write BLE peripherals (servers) and centrals (clients).
As a peripheral, you can create services, characteristics, and descriptors,
advertise, accept connections, and handle requests.
As a central, you can scan, connect, discover services, and make requests.
## SETUP
### gatt supports both Linux and OS X.
### On Linux:
To gain complete and exclusive control of the HCI device, gatt uses
HCI_CHANNEL_USER (introduced in Linux v3.14) instead of HCI_CHANNEL_RAW.
Those who must use an older kernel may patch in these relevant commits
from Marcel Holtmann:
Bluetooth: Introduce new HCI socket channel for user operation
Bluetooth: Introduce user channel flag for HCI devices
Bluetooth: Refactor raw socket filter into more readable code
Note that because gatt uses HCI_CHANNEL_USER, once gatt has opened the
device no other program may access it.
Before starting a gatt program, make sure that your BLE device is down:
sudo hciconfig
sudo hciconfig hci0 down # or whatever hci device you want to use
If you have BlueZ 5.14+ (or aren't sure), stop the built-in
bluetooth server, which interferes with gatt, e.g.:
sudo service bluetooth stop
Because gatt programs administer network devices, they must
either be run as root, or be granted appropriate capabilities:
sudo <executable>
# OR
sudo setcap 'cap_net_raw,cap_net_admin=eip' <executable>
<executable>
## Usage
Please see [godoc.org](http://godoc.org/github.com/paypal/gatt) for documentation.
## Examples
### Build and run the examples on a native environment (Linux or OS X)
Go is a compiled language, which means to run the examples you need to build them first.
# Build the sample server.
go build examples/server.go
# Start the sample server.
sudo ./server
Alternatively, you can use "go run" to build and run the examples in a single step:
# Build and run the sample server.
sudo go run examples/server.go
Discoverer and explorer demonstrates central (client) functions:
# Discover surrounding peripherals.
sudo go run examples/discoverer.go
# Connect to and explorer a peripheral device.
sudo go run examples/explorer.go <peripheral ID>
### Cross-compile and deploy to a target device
# Build and run the server example on a ARMv5 target device.
GOARCH=arm GOARM=5 GOOS=linux go build examples/server.go
cp server <target device>
# Start the server on the target device
sudo ./server
See the server.go, discoverer.go, and explorer.go in the examples/
directory for writing server or client programs that run on Linux
and OS X.
Users, especially on Linux platforms, seeking finer-grained control
over the devices can see the examples/server_lnx.go for the usage
of Option, which are platform specific.
See the rest of the docs for other options and finer-grained control.
## Note
Note that some BLE central devices, particularly iOS, may aggressively
cache results from previous connections. If you change your services or
characteristics, you may need to reboot the other device to pick up the
changes. This is a common source of confusion and apparent bugs. For an
OS X central, see http://stackoverflow.com/questions/20553957.
## Known Issues
Currently OS X vesion does not support subscribing to indications.
Please check [#32](https://github.com/paypal/gatt/issues/32) for the status of this issue.
## REFERENCES
gatt started life as a port of bleno, to which it is indebted:
https://github.com/sandeepmistry/bleno. If you are having
problems with gatt, particularly around installation, issues
filed with bleno might also be helpful references.
To try out your GATT server, it is useful to experiment with a
generic BLE client. LightBlue is a good choice. It is available
free for both iOS and OS X.
gatt is similar to [bleno](https://github.com/sandeepmistry/bleno) and [noble](https://github.com/sandeepmistry/noble), which offer BLE GATT implementations for node.js.
Gatt is released under a [BSD-style license](./LICENSE.md).
