onyx-config 1.1.1

onyx-config

"onyx-config" designed for working with configuration data in run time.

Key features:

• The ConfBundle is immutable container for save configuration data.
• A ConfBundle may be created from text file or string array in run-time.
• "#" is comment symbol in text file.
• "=" and "->" is Key to Value separators in text file.

Examples:

Configuration text file ("./conf/test.conf"):

[general] # <-- This is Global Key (GlKey)
#------------------------------------------------------------
mod_name = KPR
#  ^
#  |--- This is Key

mod_type = RptR11Transceiver
#               ^
#               |--- This is Value

[log]
#-----------------------------------------------------------------
logging = on #off
#       ^
#       |--- This is Key to Value Separator

file_name_pattern = KPR.%d{yyyy-MM-dd}.log.gz
level = info #error, warn, debug, info, trace
max_history = 30
out_pattern = %d{yyyy-MM-dd HH:mm:ss.SSS}%-5level%logger{36}[%thread]-%msg%n

[protocol]
#------------------------------------------------------------
regime = slave #master - KPR; slave - OIK;
adr_RTU = 0x0A
channel_switch_timeout = 1000 100 10		# many values in one line is possible

[data_receive] # <-- This is "data" prefix Global Key (GlKey)
#----------------------------------------------------------------------------------------------------
# Addr in Addr_out type_of_data name_of_data send_to_next channel  Formula
# KPR_adr UTS_PMZ					  priority
#----------------------------------------------------------------------------------------------------
#
0xC000	 ->  0xC000   0x0B	        XGES_Р		yes	    1      (2*{0xC000}+10)+(-0.2*{0xC179}-5)
#        ^
#        |--- This is Key to Value Separator too

0xC000~1 ->  0xC001   0x0B	      	XYGES_Р		yes	    2      (1*{0xC000}+0)
#  ^
#  |--- This is Key

0xC179	 ->  0xC179   0x0B	      	XaES_Р		yes	    1	   1*{0xC179}+0
#                      ^
#                      |--- This is possition 1 Value
#            ^
#            |--- This is possition 0 Value 
	

Source code example:

import onyx.config.bundle;

void main()
{
	/* Build ConfBundle from config file */
	auto bundle = immutable ConfBundle("../test/test.conf");

	/* get value for GlKey:"log", Key:"level" */
	auto value1 = bundle.value("log", "level"); 
	assert (value1 == "info");

	/* short form to get the value for GlKey:"general", Key:"module_name" */
	auto value2 = bundle.generalValue("module_name");
	assert (value2 == "KPR");

	/* get value for line with many values from possition 1 */
	auto value3 = bundle.value("protocol", "channel_switch_timeout", 1); 
	assert (value3 == "100");

	/* get value for GlKey:"data_receive", Key:"0xC00", position:3
	auto value4 = bundle.value("data_receive", "0xC000", 3);
	assert (value4 == "yes");
	
	/* Build another bundle from string array */
	string[] s2 = 
	  ["[protocol]",
	   "data_flow = input",
	   "[new_gl_key]",
	   "test_key = value1 value2"];	
	auto bundle2 = immutable ConfBundle(s2);
	
	/* Add two bundles. Created new bundle with data from both bundles */
	auto newBundle = bundle + bundle2;
	auto value5 = newBundle.value("log", "level"); 
	assert (value5 == "info");
	auto value6 = newBundle.value("new_gl_key", "test_key", 1); 
	assert (value6 == "value2");
	
	/* Get from bundle one global data part (in example with global key: "log")
	auto partBundle = newBundle.subBundle("log");
