rossoc

rossoc is an experimental project to generate code from sql.
Converts sql to mruby, mruby/c, or Arduino source code.

Guide

For example, SQL like SELECT din11 FROM mruby WHERE ((din1 = 0 AND din2 <= 1) OR din3 <> 9) is converted to source code like this:

# SELECT `din11` FROM `mruby` WHERE ((`din1` = 0 AND `din2` <= 1) OR `din3` <> 9)

GPIO.setmode(11, GPIO::IN)
GPIO.setmode(1, GPIO::IN)
GPIO.setmode(2, GPIO::IN)
GPIO.setmode(3, GPIO::IN)

uart1 = UART.new(1)

while 1 do
  din11 = GPIO.read(11)
  din1 = GPIO.read(1)
  din2 = GPIO.read(2)
  din3 = GPIO.read(3)

  if ((din1 == 0 && din2 <= 1) || din3 != 9)
    uart1.puts("din11=#{din11}")
  end

end

This mruby code can be output with the following command.

rossoc query -i 'SELECT din11 FROM mruby WHERE ((din1 = 0 AND din2 <= 1) OR din3 <> 9)' -o test.rb

You can also use the sleep function.
RSLEEP is the original keyword of rossoc.

rossoc query -i 'SELECT din11 FROM mruby WHERE ((din1 = 0 AND din2 <= 1) OR din3 <> 9) RSLEEP 100' -o test.rb

The code will look like this.

# SELECT `din11` FROM `mruby` WHERE ((`din1` = 0 AND `din2` <= 1) OR `din3` <> 9) RSLEEP 100

GPIO.setmode(11, GPIO::IN)
GPIO.setmode(1, GPIO::IN)
GPIO.setmode(2, GPIO::IN)
GPIO.setmode(3, GPIO::IN)

uart1 = UART.new(1)

while 1 do
  din11 = GPIO.read(11)
  din1 = GPIO.read(1)
  din2 = GPIO.read(2)
  din3 = GPIO.read(3)

  if ((din1 == 0 && din2 <= 1) || din3 != 9)
    uart1.puts("din11=#{din11}")
  end

  sleep(100)

end

rossoc is only SELECT statements are supported.
The values ​​that can be specified for the column name are din1 to din20 and ain1 to ain20. din corresponds to digital pin, and ain corresponds to analog pin.
Possible values ​​for table name are mruby or arduino.
