parse[int|real|string]array
Prototype: parseintarray(array, input, comment, split, maxentries, maxbytes)
Prototype: parserealarray(array, input, comment, split, maxentries, maxbytes)
Prototype: parsestringarray(array, input, comment, split, maxentries, maxbytes)
Return type: int
Description: Parses up to maxentries
values from the first maxbytes
bytes in string input
and populates array
. Returns the dimension.
These functions mirror the exact behavior of their
read[int|real|string]array()
counterparts, but read data from a variable
instead of a file. By making data readable from a variable, data driven
policies can be kept inline.
The comment
field is a multiline regular expression and will strip out
unwanted patterns from the file being read, leaving unstripped characters to be
split into fields. Using the empty string (""
) indicates no comments.
Arguments:
array
: Array identifier to populate, in the range[a-zA-Z0-9_$(){}\[\].:]+
input
: A string to parse for input data, in the range"?(/.*)
comment
: Unanchored regex matching comments, in the range.*
split
: Unanchored regex to split data, in the range.*
maxentries
: Maximum number of entries to read, in the range0,99999999999
maxbytes
: Maximum bytes to read, in the range0,99999999999
Example:
body common control
{
bundlesequence => { "test" };
}
bundle agent test(f)
{
vars:
# Define data inline for convenience
"table" string =>
"1:2
3:4
5:6";
"dim" int => parseintarray(
"items",
"$(table)",
"\s*#[^\n]*",
":",
"1000",
"200000"
);
"keys" slist => getindices("items");
"sorted_keys" slist => sort(keys, "int");
reports:
"$(sorted_keys)";
}
Output:
R: 1
R: 3
R: 5
