Fabian Reinartz 76a4a46cb0 pkg/textparse: refactor and add metadata handling 
Extends the parser to allow retrieving metadata.

parser on top.

Brian Brazil 4addee2bee Fix honor_labels for empty labels, prune empty labels. 
The semantics of honor_labels are that if a target exposes
and empty label it will override the target labels. This PR
fixes that by once again distinguishing between empty labels
and missing labels in this one use case.

Beyond that empty labels should be pruned and not added to storage,
which this also fixes.

Fixes #3841

Julius Volz 192e665317 rulefmt: Allow parsing from bytes instead of file 
This makes the rulefmt package more reusable for users whose rulesets are not
stored in files on disk. Concrete example: Cortex.

Julius Volz 5da0fd91db Add label matcher tests 2017-10-10 17:13:55 -07:00
Julius Volz 33c1171b9c Don't add anchoring to exported `Value` matcher field 
Instead, just make the anchoring part of the internal regex. This helps because
some users will want to read back the `Value` field and expect it to be the
same as the input value (e.g. some tests in Cortex), or use the value in
another context which is already expected to add its own anchoring, leading to
superfluous double anchoring (such as when we translate matchers into remote
read request matchers).
