updating oE to_string
to_string
include std/convert.e default namespace is convert public function to_string(object data_in, integer string_quote = 0, integer embed_string_quote = '"')
Converts an object into a text string.
Parameters:
- data_in : Any Euphoria object.
- string_quote : An integer. If not zero (the default) this will be used to enclose data_in, if it is already a string.
- embed_string_quote : An integer. This will be used to enclose any strings embedded inside data_in. The default is '"'
Returns:
A sequence. This is the string repesentation of data_in.
Comments:
- The returned value is guaranteed to be a displayable text string.
- string_quote is only used if data_in is already a string. In this case, all occurances of string_quote already in data_in are prefixed with the '\' escape character, as are any preexisting escape characters. Then string_quote is added to both ends of data_in, resulting in a quoted string.
- embed_string_quote is only used if data_in is a sequence that contains strings. In this case, it is used as the enclosing quote for embedded strings.
Example 1:
include std/console.e -- for display function include std/convert.e -- for to_string function display(to_string(12)) display(to_string("abc")) display(to_string("abc",'"')) display(to_string(`abc\"`,'"')) display(to_string({12,"abc",{4.5, -99}})) display(to_string({12,"abc",{4.5, -99}},,'@')) -- use the @ as substitute for quotes
Results:
12 abc "abc" "abc\\\"" {12, "abc", {4.5, -99}} {12, @abc@, {4.5, -99}}
