QUESTION
In my case, I want to capture repeated characters in text; at the same time, at most 3 characters before and behind the repeated patterns should be captured too. For example,
original prefix repeat postfix 1aab 1 aa b 1aaab 1 aaa b 1234aaabcde 234 aaa bcdI coined a RE string in python:
...ANSWER
Answered 2021-Jun-10 at 08:53You can use 4 capture groups, where group infix is only for capturing a single char to be repeated.
QUESTION
I'm working on a library that uses a pretty old C++ expression template (ET) engine named PETE. (I tried finding a link to its source code so I could cite it but I only found articles about it.)
Quick overview: With ET the C++ compiler builds from an expression using the operator infix-form (+,-,*,/) a C++ type which represents the expression and its operations. Central to PETE's approach is the ForEach class template that is used to later parse and evaluate the expression.
What I'm trying to do is to provide a specialized ForEach that gets used when its argument meet a specific condition. I'm trying this with partial specialisation and the use of enable_if but the compiler complains about 'ambiguous partial specialization'.
I'm happy to post other parts of the code if needed, but I'll stick to the direct class template in question (NB: I added the Enable parameter in order to make the later specializations selectable with enable_if. NB2: For the sake of a shorter post I don't include the implementation of the method):
ANSWER
Answered 2021-Jun-05 at 17:32After some time I think I have an answer.
First of all, I simplified the code to the minimum, by chopping off anything that wasn't needed to reproduce the error. It all boils down to why the partial specializations are ambiguous in the following (I'm sorry for having changed the name of the various bits, but un-bloating your code was not an easy task, at least for me):

QUESTION
There are many examples of how to read from and write to files, but many posts seem out of date, are too complicated, or are not 'safe' (1, 2) (they throw/raise exceptions). Coming from Rust, I'd like to explicitly handle all errors with something monadic like result.
Below is an attempt that is 'safe-er' because an open and read/write will not throw/raise. But not sure whether the close can fail. Is there a more concise and potentially safer way to do this?
...ANSWER
Answered 2021-May-26 at 23:40The Stdio library, which is a part of the Janestreet industrial-strength standard library, already provides such functions, which are, of course safe, e.g., In_channel.read_all reads the contents of the file to a string and corresponding Out_channel.write_all writes it to a file, so we can implement a cp utility as,

Does OCaml have an equivalent to Haskell's Do Notation?
Another way to put it - is there an easy way to handle nesting monadic operations more easily... cause this is annoying:

Answered 2021-May-26 at 12:36Yes, since OCaml 4.08, it is possible to describe let operators. For example:
QUESTION
When I manually converted Scala 2 code to Scala 3, operator precedence for my DSL changed, and it took me a long time to debug and fix. It seems the handling of : is different:
ANSWER
Answered 2021-May-26 at 06:23Your mental model just needs some tweaking.
Recall that the infix x op y de-sugars to x.op(y), except when the op ends with a colon, then it's y.op:(x). This holds true whether the op() method is native to the instance parameter or an added extension, which, in Scala-2, is handled by an intermediate implicit class.
QUESTION
I'm learning Raku and something's confusing me.
To calculate the sum of elementwise products of two lists (at least one of them finite) I was hoping to be able to write something like
...ANSWER
Answered 2021-May-19 at 20:01Is it possible to evaluate the product-sum of two lists in this way?
Yes.
Let's start with chaining:
One can write Raku code that chains right-to-left but we'll stick with left-to-right.
A left to right English reading of what you're calling "product sum" would be "sum of products of elements of these lists". So we want sum on left, product next, lists last.
There is a built in sum but no built in product, so we need to deal with the latter. One way is to write [Z*] as a reduction (which means it has to appear on the left of the lists it reduces over). Another is to write a new product function.
Putting the above together, here are some of the ways we can write a "product sum":
