kandi X-RAY | Bullwinkle Summary
[Coverage] . Bullwinkle is a parser for LL(k) languages that operates through recursive descent with backtracking. [Parser generators] such as ANTLR, Yacc or Bison take a grammar as input and produce code for a parser specific to that grammar, which must then be compiled to be used. On the contrary, Bullwinkle reads the definition of the grammar (expressed in [Backus-Naur Form] (BNF)) at runtime and can parse strings on the spot.

QUESTION
I've recently been provided a new, custom built tool for manipulating text data into a database and one feature has me stumped as I have no experience with C# and my colleagues who do haven't been able to come up with a solution due to time constraints.
The tool I've been given has an Expression Builder in order to apply rules to clean up plain text. This is the extent of the instruction I have been provided:
Use C# code to write your expressions. Use the helper 'Text' string variable to refer to the whole text or the helper 'Lines' string[] variable to refer to the individual text lines. You can also use the 'Builder' (StringBuilder) helper variable to build your output. The expression should either return a string value or a string array.
I'm creating rules to clean up data with specific keywords found at the end of the line and need to write an expression/rule that will allow me to merge the line with the specific keyword with the next line. I have a functioning rule for moving lines UP if the line starts with a specific keyword but I need to create one to merge down where lines end in a keyword.

QUESTION
Can someone provide me with a complete example of how to get a springboot PUT request to properly deserialize a @RequestBody object that has dates in it? I am getting null attributes in the object and I think it is because the serialized object has util.Date's in it.
I can see the JSON payload on the front end. It looks like this:

QUESTION
I'm new to R, and I'm playing with strsplit within a data frame. My data frame uses the following:
ANSWER
Answered 2017-Jan-19 at 19:24the error comes from the fact that data.frame coerces your character vector into a factor, which throws an error with strsplit, as said in the documentation.
Either you can do
