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
