bes-service
========

bes-service is a small bash bes library to easily create systemd service.

### Usage

add bes-service as dependency in your bes.ini file.

```
[require]
bes.service = 1.1
```

create your service following 'src/main.sh.tpl' template.
edit for example 'src/main.sh' in your bes project ('myservice' in this example) :

```
#!/bin/bash
# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#
# @author   you - url repo
# @license  licence
# @date     2017-07-07 02:21:51 CET
#
# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  BES_SERVICE_NAME="myservice"
BES_SERVICE_CHANNEL="mychannel"
 BES_SERVICE_DELAY=10
  BES_SERVICE_BOOT=0

# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
# optional - service is started, do before running
function service.on.init()
{
    service.log " >< service.on.init"
}

# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
# optional - service is stopped, do before exiting
function service.clean()
{
    service.log " >< service.clean"
}

# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
# your main service function
# oneshot if $BES_SERVICE_DELAY equal 0
# or repeat each $BES_SERVICE_DELAY seconds otherwise
function service.on.run()
{
    # do stuff
    service.log " >< do important things, every $BES_SERVICE_DELAY seconds"
}

service.launch $*
```

install bes dependencies :

```
bes-build update
```

build your project :

```
bes-build
```

then you call install your service with :

```
./dist/myservice install
```

and start/stop your service like others in systemd

```
service myservice start # stop | restart
# or
systemctl start myservice
```

inspect service log :

```
tail -f /var/log/myservice.log
```
