/*
|

A parser for parsing config files.
|
||||
|
||||
A config file can look like this:
|
||||
variable1 = value 1
|
||||
variable2 = " value 2 "
|
||||
variable3 = (value 1, value 2)
|
||||
variable4 = (" value 1 " , "value2", value 3)
|
||||
|
||||
sample of use:
|
||||
ConfParser parser;
|
||||
parser.Parse("/path/to/config");
|
||||
|
||||
if( parser.status == ConfParser::ok )
|
||||
{
|
||||
// the whole config we have in parser.table (parser.table_single)
|
||||
}
|
||||
|
||||
config syntax:
|
||||
option = list
|
||||
|
||||
list can consists of any number of items, if you're using more than one item you should
|
||||
use brackets ()
|
||||
|
||||
for one item the brackets can be ommited:
|
||||
option = value
|
||||
white characters at the beginning of the value (and at the end) will be trimmed,
|
||||
or you can use quotes:
|
||||
option = "value"
|
||||
option2 = "value with spaces at the end "
|
||||
|
||||
the form without quotes:
|
||||
option = value
|
||||
should be written in one line, so this is not allowed:
|
||||
option =
|
||||
value
|
||||
you can use a new line characters only between brackets and quotes:
|
||||
option = "this is
|
||||
a multiline string"
|
||||
option = ( value1,
|
||||
value2 )
|
||||
|
||||
but there is one requirement: the first character " or ( should be in the same line,
|
||||
so this is not allowed
|
||||
option =
|
||||
"this is wrong"
|
||||
but this is ok:
|
||||
option = "
|
||||
that is ok"
|
||||
|
||||
empty lists:
|
||||
option = ()
|
||||
this creates an empty list: parser.table['option'].empty() == true
|
||||
|
||||
option =
|
||||
this creates an empty list too (the same as previously)
|
||||
|
||||
option = ""
|
||||
but this doesn't create an empty list, it creates a list with one (empty) item
|
||||
|
||||
commentaries:
|
||||
# this is a commentary (until the end of the line)
|
||||
option = value # this is a commentary too
|
||||
|
||||
commentaries are treated as white characters, other example:
|
||||
option = ( # this is my list
|
||||
"value 1" # this is a value one
|
||||
value 2 # and this is a value two
|
||||
) # end of my list
|
||||
|
||||
overwriting:
|
||||
option1 = some value
|
||||
option1 = other value
|
||||
# always the last option is used so option1 is "other value"
|
||||
|
||||
list delimiter:
|
||||
option1 = (value1, value2, value3)
|
||||
option2 = ("value1", "value2", "value3")
|
||||
above we're using a comma ',' as a list delimiter but when using quotes (second line)
|
||||
the commas can be omitted:
|
||||
option2 = ("value1" "value2" "value3")
|
||||
|
||||
white characters:
|
||||
the name of an option cannot consist of white characters
|
||||
some option = value # this is wrong
|
||||
some_option = value # this is ok
|
||||
|
||||
which characters are allowed in an option name is defined by IsVariableChar() method
|
||||
|
||||
you can use white characters in values
|
||||
option = value with spaces or tabs
|
||||
white characters at the beginning and at the end will be trimmed,
|
||||
so if you want them use quotes:
|
||||
option = " other value with spaces "
|
||||
|
||||
special characters in quoted strings:
|
||||
option = "this is a string with \" a quote inside"
|
||||
the option will be: this is a string with " a quote inside
|
||||
\\ - means one \
|
||||
basically: \char produces char
|
||||
so:
|
||||
"\a" gives "a"
|
||||
"\\" gives "\"
|
||||
"\Z" gives "Z" and so on
|
||||
you can call UseEscapeChar(false) to turn this off
