QUESTION
The following question asks What do double-asterisk (**) wildcards mean?
Many answers there indicate that **
includes the current directory as well as sub-directories.
However, when I test this in a bash console it only appears to list files from sub-directories. The following both list only sub-directory files
...ANSWER
Answered 2022-Apr-16 at 16:06The globstar
option needs to be turned on to enable special interpretation of **/
. Otherwise, it is just two *
globs in a row which won't match the current directory.
When the
globstar
shell option is enabled, and*
is used in a filename expansion context, two adjacent*
s used as a single pattern will match all files and zero or more directories and subdirectories. If followed by a/
, two adjacent*
s will match only directories and subdirectories.
Here is the default behavior (shopt -u globstar
):
QUESTION
I'm trying to get my head around programming real mode MS-DOS in C. Using some old books on game programming as a starting point. The source code in the book is written for Microsoft C, but I'm trying to get it to compile under OpenWatcom v2. I've run into a problem early on, when trying to access a pointer to the start of VGA video memory.
...ANSWER
Answered 2022-Apr-03 at 07:23It appears your OpenWatcom C compiler is defaulting to using C89. In C89 variable declarations must be at the beginning of a block scope. In your case all your code and data is at function scope, so the variable has to be declared at the beginning of main
before the code.
Moving the variable declaration this way should be C89 compatible:
QUESTION
I have a very wide dataset which consists of hundreds of date-value column pairs - however the heading of the values column contains the reference of the site from which the data is taken. I'd like to take this header as a new "site_name" column before pivoting this data to a long format.
The data for each site is the same 2-column format, so I'd like to be able to apply a solution across the whole dataset at once.
My code below illustrates the problem on a single date-value pair
Note: I've used asterisks to mean I'm describing the column names, rather than quoting them

QUESTION
I am using Perl 5.34.0 and I want to find wether an input is only hebrew letters and some signs like the question mark, etc. Even though I found a solution with a lot of overhead, I would like to learn how to do it simpler with regular expression.
This is my solution without regular expression.
First I defined the Hebrew characters in a constant hash in a Perl module.
...ANSWER
Answered 2022-Mar-24 at 20:47You can use a relatively simple pattern match to do this.
The interesting bit here is the \p{Hebrew}
, which allows you to match every character with a specific Unicode property. The rest is just beginning ^
and end $
of string, and a quantifier +
to say one or more.
QUESTION
I'm new to Latex and am trying to make a book-style presentation. But I am quite confused by how Latex justifies text. I was told \begin
and \end
justified the text and it seemed to work until I add some \newline
and then I got this :
We can clearly see the text is justified only on the lower text and not in the top.
Both are inside a \begin{raggedright}
statement and did not used any other commands than \newline
and \textit
. The separation of the 2 text comes from a \scenechange
commands that is defined as follow :
ANSWER
Answered 2022-Mar-14 at 16:27The reason you get the second half of your text justified is that you don't have an empty line between the end of your text and \end{raggedright}

I have a trouble: can't figure out how to map result of Jooq query.
I have 2 entities: Payment method and Currency for it. Payment method contains a List inside. Both are stored in different tables.
I get one:
...ANSWER
Answered 2022-Mar-11 at 07:23If you want to nest collections in with jOOQ, then you're probably looking for the MULTISET
or MULTISET_AGG
operator along with ad-hoc conversion, which allows for type safe nesting collections directly in SQL, if your database product support SQL/XML or SQL/JSON.
The following might not be the exact query you were looking for, but you get the idea:

I would like to add an asterisk to the beginning of liner in output:
...ANSWER
Answered 2022-Mar-10 at 23:26You need the -Stream
switch to instruct Out-String
to output individual lines - by default, you'll get a single, multi-line string.
Also, you can simplify your string-insertion task with the help of the -replace
operator:
QUESTION
Please forgive me if this question is dumb.
While reading about Haskell kinds, I notice a theme:
...ANSWER
Answered 2022-Feb-13 at 00:42The most basic form of the kind language contains only *
(or Type
in more modern Haskell; I suspect we'll eventually move away from *
) and ->
.
But there are more things you can build with that language than you can express by just "counting the number of *
s". It's not just the number of *
or ->
that matter, but how they are nested. For example * -> * -> *
is the kind of things that take two type arguments to produce a type, but (* -> *) -> *
is the kind of things that take a single argumemt to produce a type where that argument itself must be a thing that takes a type argument to produce a type. data ThreeStars a b = Cons a b
makes a type constructor with kind * -> * -> *
, while data AlsoThreeStars f = AlsoCons (f Integer)
makes a type constructor with kind (* -> *) -> *
.
There are several language extensions that add more features to the kind language.
PolyKinds
adds kind variables that work exactly the same way type variables work. Now we can have kinds like forall k. (* -> k) -> k
.
ConstraintKinds
makes constraints (the stuff to the left of the =>
in type signatures, like Eq a
) become ordinary type-level entities in a new kind: Constraint
. Rather than the stuff left of the =>
being special purpose syntax fairly disconnected from the rest of the language, now what is acceptable there is anything with kind Constraint
. Classes like Eq
become type constructors with kind * -> Constraint
; you apply it to a type like Eq Bool
to produce a Constraint
. The advantage is now we can use all of the language features for manipulating type-level entities to manipulate constraints (including PolyKinds
!).
DataKinds
adds the ability to create new user-defined kinds containing new type-level things, in exactly the same way that in vanilla Haskell we can create new user-defined types containing new term-level things. (Exactly the same way; the way DataKinds
actually works is that it lets you use a data
declaration as normal and then you can use the resulting type constructor at either the type or the kind level)
There are also kinds used for unboxed/unlifted types, which must not be ever mixed with "normal" Haskell types because they have a different memory layout; they can't contain thunks to implement lazy evaluation, so the runtime has to know never to try to "enter" them as a code pointer, or look for additional header bits, etc. They need to be kept separate at the kind level so that ordinary type variables of kind *
can't be instantiated with these unlifted/unboxed types (which would allow you to pass these types that need special handling to generic code that doesn't know to provide the special handling). I'm vaguely aware of this stuff but have never actually had to use it, so I won't add any more so I don't get anything wrong. (Anyone who knows what they're talking about enough to write a brief summary paragraph here, please feel free to edit the answer)
There are probably some others I'm forgetting. But certainly the kind language is richer than the OP is imagining just with the basic Haskell features, and there is much more to it once you turn on a few (quite widely used) extensions.

After having forgotten to include it in my .gitignore file, the file 'Labb1.mpf' was accidentally commited and sent upstream. Afterwards I added the line '*.mpf' into my gitignore file, but the file still showed up under 'Untracked Files' when I ran git status and became staged when I used 'git add .'. It was still in untracked files even after a commit which removed the file upstream. Labb.mpf is in a subdirectory with this structure:
