kandi X-RAY | namespacing Summary
Namespacing adds namespaces to Ruby by taking inspiration from how Clojure handles its namespaces. It is primarly a simplification of the existing module syntax. Great for deeply nested modules or for attempting a more functional approach to writing Ruby code. I wrote a blog post about the inspiration and process of creating this code.

QUESTION
I'm following a tutorial on how to create laravel packages.
I'm using Laravel v8.42.1 (PHP v7.4.3) and jetstream package.
I'm stuck on creating a controller for my package, I always get following error when trying to connect to my url via the laraval app (

Answered 2021-May-10 at 15:27It's actually a bit strange to call them "nested libraries" since you want to call them with Lib.Utils.Whatever
. Utils
, here, is a sub-module of Lib
. Here's what I was able to do if it can help you:
QUESTION
We have two libraries - lib1 and lib2. Both the libs use a third lib say lib3. If our customer uses lib1 and lib2 in the same application using static linking, the customer faces linking issues due to symbol collision as functions from lib3 are common in lib1 and lib2.
We have access to lib1, lib2, lib3 source codes. What changes should we do to avoid naming collisions?
After reading some posts, namespacing in C++ seems to solve the problem? But will it work in our case as lib3 will still be loaded twice?
...ANSWER
Answered 2021-Feb-18 at 09:50I'll leave an answer because this won't fit inside a comment.
As I understand you deploy some kind of software development kit for lib1
and lib2
. Each SDK contains some public headers and the lib1
and lib2
static libs. Both of these libraries are statically linked with lib3
, which is an internal library.
So the SDKs could look something like this:

As part of this migration work I have been doing, I came across a monkey patched initialization of pundit. I'm understanding it for the most part but there is a part that is causing me errors:
...ANSWER
Answered 2021-Apr-25 at 17:06I'm not sure what this monkeypatch is really supposed to accomplish. But one way of avoiding the error is by not using ActiveSupport::Concern#included. Instead just use the actual Ruby hook (Module#included) that it abstracts away:
QUESTION
so I've got this small webhook endpoint that get's called with JSON data and then stores this data into a remote MongoDB Atlas database. Everything is happening locally, except from the database executions.
- Environment: Ubuntu 20.04.2 LTS
- Service: Apache2
- PHP: 8.0.3
- MongoDB: 1.8.0 // Installed via composer, required in composer.json, extension enabled in php.ini
To simulate these requests, I've locally built a PHP script sender.php
that makes a POST request via curls to my locally installed webserver to my recieving file listener.php
.
When I execute the listener.php
directly it works fine, all data goes through and get's written into the remote MongoDB Atlas database.
But when it get's called from my webhook file sender.php
I get the following error:
ANSWER
Answered 2021-Mar-30 at 07:09It turned out, that my local webserver (Apache2) used a different PHP-CLI than my development environment and therefore all the enabled extensions and configurations had no effect as soon as the request got parsed to the webserver.
Use docker kids.
QUESTION
Getting Uncaught (in promise) ReferenceError: getDefaultState is not defined
when trying to use a store reset function on a module store. Nuxt documentation on store setup unfortunately is not very thoughrough. Can anyone point me to what I'm missing to make this available on the root level?
My store reset is based on:
Vuex issue 118
The above is used here with a state function
My store setup is based on:
Latest implementation, that I actually used
Along with this very well structured answer by CMarzin
Framework documentations used:
Vuex documentation
and
Nuxt store documentation
Not related:
This is about general store usage
My setup:
...ANSWER
Answered 2021-Mar-10 at 10:03In your user/mutations.js
file you use the getDefaultState()
-function, but you need to import it in order for the mutations to know what it is. In order to import it, you also have to export it.
So your user/state.js
should be changed to this:

This is my first time asking a question so if I could be doing something better please let me know.
I have three classes, all which need to be working together. Here's an example:
...ANSWER
Answered 2021-Feb-10 at 16:19Your stack trace is pretty straightforward. It's telling you:
- You haven't successfully required your Scraper class/module.
- There's no CLI::Scraper defined in your current namespace.
- You're invoking methods on objects that aren't in scope or that don't exist in your code at all.
Address the issues above, and see where that gets you. Off the cuff, there a few concrete things you should consider as you debug your program:
Your CLI class has no way to reference a Scraper class/module outside its namespace unless you tell it where to look through importing modules or namespacing them within a common module so you can reference Foo::Scraper and Foo::CLI explicitly.
Your probably better off injecting a Scraper into your CLI initialization anyway, but you haven't shown enough code to offer a meaningful example.
Strip away all non-essential code until you can get the basics working. For example:
QUESTION
We already have flatbuffer library embedded in our software code for simple schemas with JSON output data generation.
More update: We are generating the header files using flatc compiler against the schema and integrate these files inside of our code along with FB library for further serialization/deserialization.
Now we also need to have the following schema tree to be supported.
...ANSWER
Answered 2021-Feb-05 at 16:54- Yes, trees (and even DAG) structures are fully supported. The type definition is recursive, but the data will eventually have leaf nodes with an empty vector of children, presumably.
- The integer value for
V1
is0
, and that is also the default value for all fields with no explicit default assigned. Use--defaults-json
to see this field when converting. Note that explicit versions in a schema is an anti-pattern, since schemas are naturally evolvable without breaking backwards compatibility. - You can put enum fields in structs, yes. Is that what you mean?
QUESTION
I am using PHP Version 7.3.25.
I have started experimenting with PHP Namespaces on the server-side (not least because I use ESModules on the client-side and I fully appreciate the advantages of namespacing) but I have fallen at the first hurdle - it's probably an obvious rookie error, but with no errors displaying it's difficult to guess what mistake I've made.
I have a long page of global functions - included before anything else by every page on the website - which I have prepended with:
...ANSWER
Answered 2021-Jan-23 at 16:24Yes, you either have to prefix the function with its namespace (use the fully qualified name of it) or alias the function before calling it using the use
statement (usually right after the namespace declaration - if any - or at the beginning of the file otherwise).
