QUESTION
Since I used Electron forge webpack plugin, when I execute npm start
, it will cause an error after step Compiling Preload Scripts. It says the error is inside Forge.
I check it out, it's an error in file watcher api, that mainCompilation.fileSystemInfo
is undefined, so it cannot read prop createSnapShot function.
What should I do to resolve this error and start my app?

I'm trying to use the File Watcher tool in the Jetbrains IDE (Webstorm and Rider) to automatically minify my .css files and generate .min.css files for them on the whole project.
Thing is, it keeps minifying files that already have .min.css as the extension. So I end up with files like slick.min.min.css
. I can't find any option to control what the criteria is for matching files. Is there some option to force it to ignore .min.css files, so I don't get duplicates?
I was following this guide here: https://www.jetbrains.com/help/idea/compressing-css.html#ws_css_compress_create_file_watcher with some tips from here How to Minify CSS with SCSS File Watcher in PHPStorm IDE
...ANSWER
Answered 2021-Jan-06 at 17:27As .min.css
files are still CSS files, your watcher listens to changes in all them ( because watcher Scope == Project files, File type == CSS) and produces the output.
As a workaround I can suggest excluding minified files from watchers processing:
- create a new scope (Settings | Appearance & Behavior | Scopes) with minified files excluded (like
file:.css&&!file:*.min.css
) - choose this scope as your file watcher Scope

I have been using a SASS/SCSS file-watcher in my ide for quite a while now and for the past few days I have been having issues with the encoding. At the moment I work with another developer on a software and we're using a git system to handle the files. A few days ago I pulled an update from git and sice then there seems to be something wrong with the encoding from the scss to css files. For example: When the file-watcher compiles the font-awesome scss files to css it changes the output from:

QUESTION
Hi I am using C++ with the Qt framework for a Windows program. I use Qt threads but this situation could relevant for other thread APIs as well. I am dedicating a worker thread to monitor for directory changes using ReadDirectoryChangesW and WaitForMultipleObjects from the Win API. I want to be able to cancel the worker thread gracefully from the main thread. I have read about CancellIOEx that takes a handle and OVERLAPPED parameter but these data types are both pointers. Is there some safe way to pass these pointers from the worker thread to the main thread safely? Is there a better way of doing things?
Here's some code from here but using WaitForSingleObject instead of WaitForMultipleObjects, the function will be called from the worker thread. Am I allowed to post this code from the link? Also see here for valuable information about ReadDirectoryChangesW outside of the Windows Dev Center.
Thanks!
...ANSWER
Answered 2020-Apr-21 at 06:35The main thread could create the OVERLAPPED
struct and give it to the thread to use, rather than the other way around. However, trying to cancel the I/O from the main thread would be a race condition either way. Since your worker thread has to make a new call to ReadDirectoryChangesEx()
after every directory event, it could be between calls to ReadDirectoryChangesEx()
when the main thread wants the worker thread to terminate, thus calling CancelIoEx()
when there is no I/O in progress would be a no-op.
Instead, create another event object for the main thread and worker thread to share, in addition to the event object that you are creating for the I/O. Have the worker thread wait on both events at the same time with WaitForMultipleObjects()
, and then the main thread can signal the shared event when it wants the worker thread to terminate.
WaitForMultipleObjects()
will tell the worker thread which event was signaled. If the shared event is signaled, the worker thread can cancel its I/O in progress via CancelIo/Ex()
before exiting.

Answered 2020-Feb-04 at 04:55As increasing the limit didn't work for me, I tried a different approach. I didn't add my node_modules
files to the watcher.
From my experience the best fix would be to expose the watcher configuration where one could define to ignore any folders or files of their choosing, not just node_modules.

QUESTION
I'm trying to build a new project with ES6 modules without bundling. I still want to use babel-7 to translate TypeScript and JSX to JS. I find it hard to figure out how to set up a development-server for it. I couldn't find any kind of "babel-dev-server" that works similar to webpack-dev-server (hot-module-reloading, browser-sync, file-watcher).
One possibility would be to use browser sync as a static server on e.g. dist
and run something like babel src --out-dir dist --watch
in parallel. But this excludes hot-reloading and seems a bit clumsy to me. Besides, it would still be useful for build- and dev-steps if you could give the JS-files a hash to control caching better. Or can I configure a build-tool like webpack so that it doesn't perform bundling but still performs some transformations (like putting the hashs in the filenames in imports)?
ANSWER
Answered 2018-Oct-22 at 19:22With webpack and source maps, it shouldn't matter that it changes your code. While this can be a challenge to set up initially, once you get it working you can look at your original source code in the browser debugging tools exactly as they appear to you on disk. The VS Code editor also does a good job of supporting this feature, allowing you to set breakpoints and look at the values of variables directly in your editor without having to use the browser developer tools.
However, if you are still set on trying to get this to work with your original source files then you are right that your ES6 code should just work in most modern browsers
For live reload you could check out the npm livereload package.
Or you could roll your own and figure out how webpack-dev-server does it. They use the chokidar npm package to watch the file system for changes and then they notify the broswer via web sockets. You could probably throw something together that's similar with a little effort.
Here is how webpack-dev-server initiates it:

I recently added a SCSS file-watcher in PhpStorm and generally it does what it is suppose to. The only issue I have is that it creates a new folder within the sass-folder everytime it synchronizes. The new folder doesn't have a name but it includes the files of the sass-folder.
These are the settings of the file watcher:
Scope: The sass-folder
Arguments:
--style expanded --no-cache --update $FileName$:../css/$FileNameWithoutExtension$.css
Output paths to refresh:
../css/$FileNameWithoutExtension$.css:.../css/$FileNameWithoutExtension$.css.map
Is there something wrong with the settings?

Install file-watcher
You can use file-watcher like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
