I am using vue.js (2.6.5) and webpack (5.77.1), and I enabled the source map feature in development env, with simple config as below:
mode: 'development',
devtool: 'eval-cheap-module-source-map',
.....
Well, the source map feature indeed works, but what confuse me is when you search a file name, there will be multiple files with same file name listed, see as below:
Only one of them is the exact original file definition, other files are definitions of render function of vue.js and some others. Every time I need to click on each one of them to check which is the exact original file, this annoys me, does any one know how to only show the exact original file ?

I'm not sure what to call the files, but the context is that I have a bunch of data that I would like to ship with my app. I need to find a way to store this data so that I can load it into the database. (Or better yet, just ship it with a prefilled db)
Here are the solutions that I've seen:
Storing the data in code as a json blob I can't do this because I have quite a lot of data, a few MB or so and I would like to be able to compress it.
Load a file from the public folder
I think this is a create-react-app specific API and I did not use that. But if there's a way to get a public or static folder to read arbitrary files from, that'll be great.
Read a file using react-native-fs
I'm not sure where to put the file in my application so that I can access it. This seems to give me an empty folder to write files to. I don't know where in my app directory I can put the files if I want it to be read by this.
I would also like to have these files compressed, and only loaded when I need them to be. I think using a require('path/to/file.json') loads the file every time I use the app.
How would I go about reading a file from my app?
I'm coding for android if that matters and the database I'm using is watermelondb.
You need to use react-native-asset to put files to your project and access them with require keyword.
Example for file with path ./assets/files/some-file.mp3:
Add or modify react-native.config.js
module.exports = {
project: {
ios: {},
android: {},
},
dependencies: {
},
assets: [
'./assets/files'
],
};
Run npx react-native-asset
Use the file:
const file = require('./assets/files/some-file.mp3')
I'm building an app with react-native, and I'm trying to use the react-native-fs module to list out a series of images located in the app folder. The images are located in a folder in the app project folder named 'data', so for example if I want to display one of the images, this works:
<Image source={require('./data/boo.png')} />
However when I try to use react-native-fs to list out all the files in that folder like so:
RNFS.readdir(RNFS.DocumentDirectoryPath+'/data')
.then((result) => {
console.log('GOT RESULT', result);
})
.catch((err) => {
console.log(err.message, err.code);
});
I get the error 'Folder does not exist'. Also when I remove the +'/data' the only result listed is a file by the name of 'ReactNativeDevBundle.js', with a path of '/data/user/0/com.awesomeproject/files/ReactNativeDevBundle.js'. Is this the expected behavior? If this is the expected behavior, and I am doing something wrong, how can I access the file folder I want from within the app? Side question, if I wanted to provide that Image tag with an absolute path, what would that look like.
First, are you creating the data folder in running time? or why do you think that's where the files are?
Second,

Yes, this is the expected behavior, RNFS.DocumentDirectoryPath goes directly to /data/user/0/com.awesomeproject/files/, this is where you should create the data folder if you want to keep using the same code you currently have
EDIT:
According to one of the contributors of the package: if your folder is within the javascript-space this package won't work.
If you're using android, you may need to put the files into the assets-folder within the android-folder. Then you should be able to use readDirAssets.
I recommend to read Differences between File Source
Excerpt:
Normal Files: These files are created by your app using fs, or fetch API, you can do any operation on these files.
Asset Files: Compiled into the app bundle so generally they're on
readonly mode
I'm trying to change the eglfs mouse cursor graphics for my embedded linux QT application (QT5.5). I have the new cursor atlas PNG and the new JSON descriptor file, but the documentation is rather vague:
".. a custom cursor atlas can be provided by setting the QT_QPA_EGLFS_CURSOR environment variable to the name of a JSON file. The file can also be embedded into the application via Qt's resource system."
I'd prefer to keep everything within the resource system if possible but I can't work out how to do it.. do I need a specific qrc file containing the path to the JSON file? I assume that the PNG file would also need to be added as a resource so that it gets built into the application?
If adding it via the resource system is a bad idea where's the correct place to set the QT_QPA_EGLFS_CURSOR environment variable? I'm currently specifying the platform on the command line via "-platform eglfs"; will this be ok or will I need to set the platform to eglfs in the build?
After much trial, error and digging around I have found the solution that I was looking for within the resource system.
Create a new resource file called "cursor.qrc", the contents of which needs to be two lines:
path/to/your/custom-cursor-atlas.png
cursor.json
The first line (path to your cursor atlas) must be relative to your resource directory.
You then need to put the JSON file (contents as described in the documentation) in the root of your resource directory. It must be called "cursor.json", and its image location line must must match the location in your new resource file and be of the format:
"image": ":/path/to/your/custom-cursor-atlas.png",
This will then include your cursor atlas in resources, and Qt will find it when your application starts.
Run time solution example:
export XDG_RUNTIME_DIR=~
export QT_QPA_EGLFS_CURSOR=~/cursor.json
In the cursor.json:
"image": "cursor.png",
Put your custom cursor.png atlas into your home dir (~) then run the Qt app from there.
I use webpack for JS and now I want to use it for styles. I have a lot of styles in different folders and i want to compile them all without requiring each of them mannaully. The question is how to gather all the .less files in the folders and compile them via less-loader?
This isn't how webpack is meant to work, really. If you really want to do this, grunt/gulp is going to be a better choice.
Webpack's require mechanism ensures you build only the CSS you need for any given entry point, and gives you dependency management as well. If you do want to use webpack, but don't want to use the style-loader to insert them into the DOM etc., you can use the Extract Text plugin to build your compiled CSS into a separate file.
I found some workaround using require.context.
First you need to create a js file in the root of the styles folder if you don't have one.
Use this code if you use css or less and always extract them
require.context('./', true, /(\.less$)|(\.css$)/);
First argument is relative path to folder in which webpack should search for the files, second tells that it should search in subfolders and the last one is regexp of the extension of the files that webpack should require. Then you need to requre this file or use it as entry point. This works if you use extract-text-webpack-plugin but doesn't work otherwise.
Using styles without extracting them to style separate file
The example above doesn't work if you don't extract them because webpack generate modules with styles but doesn't execute them. This is complete example that works in both cases:
(function (requireContext) {
return requireContext.keys().map(requireContext);
} (require.context('../', true, /(\.less$)|(\.css$)/)));
Live templates -> edit variable.
I can specify groovy file in variable settings: groovyScript("C:/test.groovy")
Where is "home" directory to store my script? i Want something like that:
groovyScript("test.groovy")
For easy export config to another PC.
groovyScript's argument can be either the script text itself or a filename. In the latter case the filename is relative to idea or idea/bin directory. It's probably better to use absolute paths.
In recent IDEA builds you can share live templates by copying them to clipboard (Ctrl+C, see https://youtrack.jetbrains.com/issue/IDEA-141077)
