# Go CMW
`go-cmw` is a [cmw](https://gitlab.com/elazkani/cmw) rewrite in [Go](https://golang.org/).
# Usage
`go-cmw` features a good command-line interface thanks to `kingpin.v2`.
```console
$ go-cmw --help
usage: go-cmw [<flags>]
A small terminal wrapper around the wttr.in weather endpoint.
Flags:
--help Show context-sensitive help (also try --help-long and --help-man).
-L, --location=LOCATION Specify explicite location (--expert-mode)
-l, --language=LANGUAGE Specify explicite language (--expert-mode)
--v2 Display Data-Rich output
-m, --metric Display weather in metric
-u, --uscs Display weather in imperial
-M, --meter-second Display wind in m/s
-z, --zero Display current weather
-o, --one Display current weather + 1 day
-w, --two Display current weather + 2 days

-O, --one-liner One liner outpet (for the terminal multiplexer lovers out there)
--format=FORMAT Specify a format query (e.g. "%l:+%c+%t") (--expert-mode)
--free-style=FREE-STYLE Specify a free-style API call (--expert-mode)
--expert-mode Print expert mode information
--version Show application version.
```
On top of the following command-line flags, `go-cmw` can also take advantage of environment variables `--expert-mode`.
```console
$ go-cmw --zero
Weather report: Paris
\ / Clear
.-. 1..4 °C
― ( ) ― ↗ 11 km/h
`- 10 km
/ \ 0.3 mm
```
`go-cmw` makes it easier to integrate the weather with your favorite terminal multiplexer.
```console
$ go-cmw --one-liner
Paris: ☀️ +4°C
```
Example configuration for `tmux`.
```console
# Let us update sensibly every 30 minutes
set -g status-interval 1800
WEATHER='#(go-cmw --one-liner)'
set -g status-right '... $WEATHER ...'
```
# Expert Mode
The commands labeled `--expert-mode` have special functionality attached to them.
Some of them can be used as environment variables while others override `go-cmw`
default functionality to provide the user with more flexible interface.
For more information about commands labeled `--expert-mode`
```console
$ go-cmw --expert-mode
```

This project is a journey of learning Golang.
If you would like to make an MR, please go right ahead, it would be a good learning process for me.
