What does a generic type that `extends boolean = false` mean?

Answered 2022-Mar-28 at 12:53

T extends X = Y, where Y is a subtype of X, simply gives a default type for T. boolean is equivalent to true | false, therefore false is a subtype of boolean.

Here's a simplified example. Without using a default subtype:

QUESTION

Minimal `set cover` solution in Clojure

Asked 2022-Mar-25 at 11:25

I've been trying ways to distill (a lot of) database index suggestions into a set of indexes that are applicable to most databases. To do that it turns out I need to solve a pretty basic but NP complete set theory problem: the minimum set cover problem.

This means that given a set of sets, select a subset of sets s that covers a certain domain u, but if u isn't given make it the union of s. The most optimal subset of sets is the one reaching a certain minimum, usually the minimal amount of sets, but it could also be a minimum in total weight if the sets are weighted.

Here's a Clojure version of the greedy set cover algorithm i.e. selects a set which covers the most uncovered elements at each iteration. Rather than use loop/recur to build the complete result, it lazily returns each result element using lazy-seq:

QUESTION

Split log message on space for grok pattern

Asked 2022-Feb-11 at 08:15

I am two days new to grok and ELK. I am struggling with breaking up the log messages based on space and make them appear as different fields in the logstash.

My input pattern is: 2022-02-11 11:57:49 - app - INFO - function_name=add elapsed_time=0.0296 input_params=6_3

I would like to see different fields in the logstash/kibana for function_name, elapsed_time and input_params.

QUESTION

Is there an official (complete) BNF or EBNF for the CLIPS language

Asked 2022-Jan-21 at 17:41

I am looking for an official BNF/EBNF for The CLIPS Programming Language, so that I can write a parser/interpreter that groks (understands) CLIPS rules.

I have searched online, including the official CLIPS documentation, but I have only managed to find sections of the BNF (not the entire BNF).

Does anyone have a source for the COMPLETE (E)BNF for the grammar?

...

ANSWER

Answered 2022-Jan-21 at 17:41

The only BNF available is from Appendix G, CLIPS BNF, of the Basic Programming Guide. That covers all of the constructs and function calls that are not special forms. For special forms (functions that have non-standard syntax such as the fact query functions), the BNF is specified in the section describing that function.

ANSWER

Answered 2022-Jan-20 at 20:48

Like explained in the comment from @PitaJ, *acc.entry(word).or_insert(0) += 1 has the type () while the compiler expects fold()'s callback to return the next state each time (it is sometimes called reduce() in other languages, e.g. JavaScript; in Rust; fold() allows you to specify the start value while reduce() takes it from the first item in the iterator).

Because of this, I feel like it is more appropriate use case for a loop, since you don't need to return a new state but to update the map:

QUESTION

Haskell list of tuples vs tuple comparrison

Asked 2022-Jan-12 at 00:58

I'm playing with my first non-trivial (in my eyes) attempt at something in Haskell. I'm probably going to ask questions about each part to compare my coming-from-long-term-relationship-with-c-like-languages attempt to what you-as-seasoned-functional-programmer might do. Luckily Haskell makes it hard to fall back on straight c-to-haskell code conversion. You have to learn how to do it right - and I want to.

For this part, I have a [2uple] and a 2uple. I want to know if any item in the 2uple is in any of the items in the [2uple].

The version refers only to when the option was added. I had the same error and found out that arguments have changed since version 13.0. Unfortunately, there is no documentation of changes of the arguments between versions.
