Does anyone know the file extension for Hack? I've looked pretty much everywhere, and can't seem to find it. Thanks
HHVM supports 4 file extension for hack .hh, .hck and .hack.
starting from hhvm 4, hack now uses the .hack file extension by default which doesn't require the <?hh opening tag.
We now recommend using the .hack file extension if your editor/IDE support it;
files with this extension are always strict, and do not require or allow a <?hh header line.
For example, this is a complete .hack file:
#!/usr/bin/env hhvm
<<__EntryPoint>>
function main(): noreturn {
print("Hello, world!\n");
exit(0);
}
example.hh / example.hck / example.php :
<?hh // strict
<<__EntryPoint>>
async function main(): Awaitable<void> {
print 'hello, world';
}
example.hack :
<<__EntryPoint>>
async function main(): Awaitable<void> {
print 'hello, world';
}
The vim plugin for hack uses the extension .hh for hack files

I have read something about it in wikipedia: https://en.wikipedia.org/wiki/Hack_(programming_language)
and I think that you can use .php because it should be similar to php.
Hope it will help you :)
Hack was created by Facebook as a dialect of PHP. They use .php files for their projects write in hack.
** -- UPDATE 2020 -- **
Today on their hite Hack recomendo use .hack as extension https://docs.hhvm.com/hack/getting-started/tools
vscode Hack languae extension continue to use .php as extension on their examples https://marketplace.visualstudio.com/items?itemName=pranayagarwal.vscode-hack

I'm not expert with cmake building and today I faced with following:
When I build project locally (using Windows and mingw) everything builds fine. But under git lab CICD environment (debian) I got the next error:
... no template named 'vector' in namespace 'std'
is included in this file but not directly - myfile.cpp includes myfile.h and myfile.h includes
Why this happens? How can I reproduce this behavior locally (some cmake options or something like this)?
Thank you!
Update: This is an example issue making code. I don't want to build this under mingw, instead of this I want to get similar error as under CI/CD environment (... no template named 'vector' in namespace 'std')
---my.h---
#include <vector>
---my.cpp---
#include "my.h"
std::vector<int> int_vector;

I have a project with multiple files which all depend on each other which worked fine. I added another file and added the use crate::asteroid::Asteroid syntax to another file.
When I compile it says
unresolved import "crate::asteroid"
This worked with all the other files. What is wrong?
Project layout:
/src/
asteroid.rs
command.rs
direction.rs
game.rs
main.rs
point.rs
ship.rs
The use keyword will import only the path specified, so when you use crate::asteroid::Asteroid only the Asteroid object will be imported, but not crate::asteroid. In order to import both, you can use:
use crate::asteroid::{ self, Asteroid };
Here self is referring to crate::asteroid. You will then be able to access both asteroid and Asteroid

gladLoadGLLoader() fails because glGetString is not found [closed]
Closed 3 years ago.
As it seems to be a larger problem to understand my question: It is NOT about any source code or programming implementation, it is about linking an existing and working program! So let me try that again:
I have an application which runs on both, Windows and Linux and makes use of the GLAD-wrapper for OpenGL. (For all the people which never heard about GLAD: is is a wrapper around OpenGL/MESA which ensures proper symbol loading for a defined subset/version of OpenGL). It works smoothly for Windows but recently I found it is not working for Linux any more (Ubuntu 18.04 LTS to be more specific).
The problem is: the call to
glGetString = (PFNGLGETSTRINGPROC)load("glGetString");
in function gladLoadGLLoader() returns NULL, means the library function glGetString can't be found any more. To clarify this too: not the function glGetString() is returning NULL, when trying to retrieve a function pointer to glGetString the NULL is returned as the function could not be found for some reason.
So my question is: what Linux-library would provide the function glGetString()?
Thanks!

Attribute Error: module 'Orange.widgets.gui' has no attribute 'WebviewWidget'
Part of the source code importing WebviewWidget
When I tried importing the module Orange.widgets.utils.webview and when I look for WebviewWidget attribute...there is none...only a description about it. Here is the text in the description of the module:
DESCRIPTION
This module holds our customized WebView that integrates HTML, CSS & JS
into Qt. WebviewWidget provides a somewhat uniform interface (_WebViewBase) around either WebEngineView (extends QWebEngineView) or
WebKitView (extends QWebView), as available.
Problem solved!!! The problem was QtWebKit was not installed in my system...installed it and it worked fine...I also included the pyqt5 and debug package...

I am finally documenting Hotplate. I really believe that documentation should Teach, don't Tell -- if you read the initial README.md in Hotplate you will see what I mean.
However, I do think I need some "telling" documentation (to be used as a quick reference once you've read the "Teaching" side of things) for Hotplate.
At the moment, I have this in my code:
/**
* Load all modules that are marked as "enabled"
*
* This function will require and register all modules in modulesFullPath
* that satisfy the `filter` regexp.
*
* modulesFullPath is actually optional: when not there, it defaults
* to the node_modules directory belonging to the current instante of Hotplate
*
* #param {filter} The regexp which will filter the modules to load
* #param {modulesFullPath} (optional) The full path of the modules to load
*
* #api public
*/
I copied this format from another NodeJS project.
Now, the question:
"What's the easiest possible way to turn something like this into actual documentation?"
Consider that:
Hotplate is made up of multiple, small sub-modules.
Each module has a server "main" file which does pretty much everything
Each module defines one or more "hooks" which I would like to document (something like "List of implemented hooks)
Each module can call several hooks, which I would like to document (something like "List of called hooks")
So, what's the easiest, sort-of automatic way to go about this?
Merc.
YUIdoc is very good at handling that style of remarks and generates very nice documentation from it.
