I'd just like to interject for a moment. What you’re referring to as C++, is in fact, C/C++, or as I’ve recently taken to calling it, C plus C++. C++ is not an programming language unto itself, but rather another free component of a fully functioning C system made useful by the libc, preprocessor and vital system components comprising a full programming language as defined by POSIX. — Tinus Lorvalds. std replacement for C++.

QUESTION
How is the match
expression implemented at a high level? What happens under the hood for the compiler to know how to direct certain strains of code to one branch vs. the other, figuring it out at compile time? I don't see how this is possible without storing type information for use at runtime.
Something like this example:
...ANSWER
Answered 2022-Mar-04 at 23:16A match
expression does not need runtime type information; as a match
only accepts a single expression of a single known type, by definition it can leverage compile time information.

match
at compile time vs runtime
At compile time, every match
expression will be verified to be exhaustive: all possible shapes of the value are handled.
At run time, the code will determine which specific match arm is executed. You can think of a match
as implemented via a fancy if
-else
chain.
As we humans tend to be not-extremely-precise when communicating, it's highly likely that some resources blur the line between these two aspects.
Concretely focusing on an enumEnum variants are not standalone types. That is, given an enum Foo
, Foo::Bar
is not a type — it's a value of type Foo
. This is the same as how false
is not a type — it's a value of type bool
. The same logic applies for i32
(type) and 42
(value).
In most cases, enums are implemented as a sea of bytes that correspond to the values each enum variant might be, with each variant's data layered on top of each other. This is known as a union.
Then a discriminant is added next to this soup of bytes. This is an integer value that specifies which variant the value is. Adding the discriminant makes it into a tagged union.
Matching on an enum is conceptually similar to this pseudo-Rust:

I am playing around with a dataset and practicing out some visualizations using ggplot2. My dataset has a column year with 'int' datatype. While plotting, the years get converted to decimal forms. I do not want that.

This is my first time programming in rust (I'm currently reading the book) and I recently had a need to scrap a list of diseases and conditions for this site, after trying out several guides, I ended up with this small snippet. I'm currently stuck iterating through a ol

QUESTION
I work on a Laravel 7 webapp on my local machine (MacOS Cathalina). For debugging I use VSCode, PHP Debug and Xdebug (3.0.4).
When I open a page in the browser in debug mode, the execution stops on the first line with a breakpoint as expected.
However, when I run a php artisan
command from the terminal, the execution does not stop on the breakpoints at all. I know that the code runs as I can print out traces to the log.
I use the "Listen to XDebug" option in VSCODE and this used to work in the past and I'm not aware of changing anything.
I tried to add all possible configs to my php.ini, but it did not help (after restarting my MAMP):
...ANSWER
Answered 2021-Nov-23 at 20:52Finally with the help of @LazyOne I could figure this out.
The root cause of the problem was that due to a macOS update my terminal in VSCODE was replaced with a new terminal, zsh.
This terminal did not have the right php path/version configured, therefore when I ran the artisan commands from the command line, I run it with the default php version without Xdebug installed.
When I changed the path to the php version installed under my MAMP package, it just worked. To make this more convenient, I added an alias to the zsh configuration file pointing to the right php version.

I'm using a dataset with several thousand words and over 60 values associated with each word. Most of the words are unique, but there are a few that have been duplicated. I'd like to merge these and replace the associated values with the averages. If there's a way of doing this without having to specify which words are duplicated, that would be great.
So just going from this:

QUESTION
I have a Google Sheet that contains extracted metadata from a large amount of files that I transferred from CDs to a server. I am currently working on creating a description for these materials to include in a finding aid. I found it easiest to work in Excel or Sheets because the PUI we use to output our finding aids utilizes a spreadsheet upload plugin.
I've been using pivot tables in Google Sheets to sort through all of the data with little issue except when I need to generate a date range for the files contained in one CD. Essentially, I'm creating a pivot table that contains rows for the URI, Filename (in this case I'm filtering for folder name only), and date_modified. The data looks something like this:
URI FILENAME DATE_MODIFIED URI1 FOLDER1 2000-01-01 URI1 FOLDER2 2000-01-01 URI1 FOLDER3 2000-02-01 URI1 FOLDER4 1999-12-02 URI2 FOLDER1 2001-01-20... and so on.
I'd like to generate a date range for each unique URI. I realize I could just go through each unique URI and manually extract that data but I have a LOT of these to go through so I don't think it is the most efficient use of my time. Especially, when you notice that the dates do not follow a chronological order. I'm thinking that pivot tables are not going to help me here so if anyone has other suggestions I'm happy to listen but brownie points if anyone has a solution that works in Sheets!
