GYP variable based on build configuration - node-gyp

Is it possible to define a GYP variable whose value depends on the choice of build configuration?

Just use variable $(BUILDTYPE) or $(ConfigurationName).

Looks like it's impossible according to this wiki page:
Perform “early” or “pre” variable expansion and conditional evaluation.
Merge target settings into configurations as appropriate.

I think it's possible if you mean distinctions between 'Debug' and 'Release' by the 'build configuration'. Try to add the following in your *.gyp file:
'configurations': {
'Debug': {
'variables': {
'some_variable%' : 'debug_value',
'Release': {
'variables': {
'some_variable%' : 'release_value',

TypeScript with Relay: Can't resolve generated module

In my MessageItem.tsx component I have the following code:
const data = useFragment(
fragment MessageItem_message on Message {
message as any
After running relay-compiler --src ./src --schema ../../schema.graphql --language typescript --artifactDirectory ./src/__generated__, a module named MessageItem_message.graphql.ts gets generated.
But when I run the app it gives me an error:
Failed to compile.
Module not found: Can't resolve
The reason is only components at the src root can refer to the right path (./__generated__), whereas components in a folder actually need to refer to the path (../__generated__) but it's not doing so.
How can I configure the path?
Edit .babelrc to point to the artifactDirectory
// .babelrc
"plugins": [
"artifactDirectory": "./src/ui/graphql/types"
Remove "--artifactDirectory ./src/__generated__" from the relay-compiler options.
By default it seems the Relay compiler puts a "__generated__" directory in the directory with any source code containing GraphQL.
As a result any "./__generated__" references anywhere and at any level in the source code hierarchy now work as they should.
Thanks to #ThibaultBoursier for the pointer.
PS I wonder if the --artifcactDirectory option is just meant to be used to change the name of the artifact directory, rather than its location?
Just moments ago I ran into the same issue. The reason is that the relay-compiler is using the artifactDirectory setting to decide where to put the generated files, but the babel-plugin-relay exposing the graphql tag needs to get the very same argument otherwise it just attempts to include a colocated relative file.
I fixed it in my case by configuring the plugin with a babel-plugin-macros.config.js file as follows (where the artifactDirectory is the same as the one supplied to the relay-compiler):
module.exports = {
relay: {
artifactDirectory: "./src/ui/graphql/types",
This solution assumes you are using the macro via babel-plugin-macros, otherwise you might need to supply that argument via the .babelrc file but I have no experience with that unfortunately.

ExtJS 6 What package should I require for Ext.ux.colorpick.Field to work?

I want to use Ext.ux.colorpick.Field (modern toolkit), but can not figure out what should I require for it to work.
I've tried ext-ux-colorpick package within app.json, but it leads to an error:
Failed to resolve dependency Ext.form.field.Picker for file Ext.ux.colorpick.Field.
Any suggestions?
If you want to use ux widgets you need to require it in app.json like:
"requires": [
And in app.js or in some add in requires.
requires: ['Ext.ux.colorpick.Field']
Solution was to:
1 - Install package with npm install #sencha/ext-ux (not globally).
2 - Change packages path in the workspace.json to ${workspace.dir}/node_modules/#sencha:
"packages": {
"dir": "${workspace.dir}/node_modules/#sencha",
"extract": "${workspace.dir}/node_modules/#sencha/remote"
3 - Add ux to the requires in the app.json.

detekt NoUnusedImports not reported

In my Android gradle project, I added detekt v1.0.0.RC8.
I generated default .yml file by executing:
./gradlew detektGenerateConfig
and ran the check:
./gradlew detektCheck
The plugin found a couple of issues of type TooGenericExceptionCaught, MaxLineLength but not unused imports that I added in the code to see if detekt catches them.
These lines are in my default-detekt-config.yml
active: true
autoCorrect: true
Thanks for any pointers!
The NoUnusedImports is a rule that is wrapped from ktlint. Did you add the ktlint wrapping jar as a dependency with:
dependencies {
detekt "io.gitlab.arturbosch.detekt:detekt-formatting:[version]"
Alternatively you can also use the detekt rule that detects UnusedImports by enabling the rule in your config.yml:
active: false

How to not show warnings in Create React App

I'm using create-react-app from Facebook, when it starts via 'npm start' it shows me a list of warnings, such as:
'Bla' is defined but never used
Expected '===' and instead saw '=='
I don't want to see any of these warnings, is there a way to supress them?
For local Eslint, add a file to your project named .eslintignore and add any directories or files you want to ignore:
Though you might as well remove it entirely at this point.
This doesn't work with building or starting the code however, if you are using create-react-app. There is no way to disable Eslint without ejecting because it's built into react-scripts. Anytime any you build or start the server, it will run eslint using its internal configs aside from special cases defined in package.json. The only way around that is to eject or prepend each file with the disable comment as mentioned elsewhere. See this issue on Github for more information.
Those warnings come from eslint. To disable them add /* eslint-disable */ at the top of the file you don't want to follow the eslint rules.
For specific eslint warning supression insert the following code at the beginning of the file.
/* eslint-disable react/no-direct-mutation-state */
My rep is not high enough to comment on #fly's excellent answer, so I'll C+P it to add this instead:
For anyone looking for a temporary but quick and effective workaround for disabling console warnings from DevTools, this might do the trick.
Disclaimer - this might not work on versions that are not mine(react-scripts v3.0.1, react-dev-utils#^9.0.1), so use it at your own risk.
enter this directory
look for this function(should be around line 114)
function handleWarnings(warnings) {
either add the return at the start of function printWarnings() (line 124), or comment out the call to printWarnings() in line 145.
restart, eg with npm run start, for change to take effect.
This way, the hot reloader continues to work, but the annoying warnings which have already been caught in my editor are not output in the browser.
Recently the ability to add your own editor configurations was added, this can be used to "partially" disable the functionality of ESLint. You just need to create a configuration file in the root directory.
"parser": "babel-eslint"
If you create a new application, it will by default come with a pre-filled eslintConfig object in the package.json
To Completely Remove eslint warnings, what you can do is create a file named .eslintignore add * and save it. You wont see any more warning.
To Remove warnings from a particular folder means in the .eslintignore file add that folder name
You can also do this in the file level also. Add the following in the beginning of the file
/* eslint-disable */
To ignore the next line warning in a file
// eslint-disable-next-line
If you want to disable warnings in DevTools
Open the Console Tab.
Default levels/Custom levels -> uncheck Warnings
Set the DISABLE_ESLINT_PLUGIN environment variable:

function handleWarnings(warnings) {
and add a return statement right after it.
Your code should end up looking like this(if you're using webstorm)
That should shut the webpackHotDevClient.js:{whateverLineIdontCare} right up.
If you're using create-react-app, then you can go into the package.json and edit the eslintConfig value. I just wanted to disable the "eqeqeq" and "no-unused-vars" rules, so mine looks like this:
"eslintConfig": {
"extends": [
"rules": {
"eqeqeq": "off",
"no-unused-vars": "off"
You'll have to re-run npm start for it to take effect.
Add a .eslintignore file and add
You can read more about this at
You can use craco and configure craco.config.js for example
module.exports = {
webpack: {
configure: (webpackConfig) => {
const ignoreWarnings = [{ module: /some module/, message: /some message/ }]
return { ...webpackConfig, ignoreWarnings }

You can disable the typescript and/or linting errors with setting the environment variables in .env

Paypal SDK Class Name Conflicts

I want to use Paypal Adaptive Payments and Paypal Adaptive Accounts libs in my CakePHP 2.4.x application. I am loading them via composer. My composer.json file looks like this:
"require": {
"config": {
"vendor-dir": "Vendor"
Both libs contain Paypal/Types/Common/RequestEnvelope.php and for each lib they are different. I'm running into a conflict with this class name where the right one isn't being used. I believe the solution is to use autoload in my composer.json. I've read the documentation and don't believe I'm using it correctly. Here is what I'm attempting:
"require": {
"config": {
"vendor-dir": "Vendor"
"autoload": {
"psr-4": {
"AdaptivePaymentsLib\\": "Vendor/paypal/adaptivepayments-sdk-php/lib",
"AdaptiveAccountsLib\\": "Vendor/paypal/adaptiveaccounts-sdk-php/lib"
And in my controller I'm attempting to call RequestEnvelope like this:
$requestEnvelope = new AdaptivePaymentsLib\PayPal\Types\Common\RequestEnvelope("en_US");
It is not being found. Active Accounts was only recently added to the project. Previously getting the request envelope worked fine with $requestEnvelope = new PayPal\Types\Common\RequestEnvelope("en_US"); so it was only with the addition of the accounts which presented the conflict and caused the breakage.
You should not define autoloading for your dependencies - that is the task for them to solve.
If you look at the composer.json file for paypal/adaptivepayments-sdk-php, you see:
"autoload": {
"psr-0": {
"PayPal\\Service": "lib/",
"PayPal\\Types": "lib/"
If you look at the same file in paypal/adaptiveaccounts-sdk-php, you see:
"autoload": {
"psr-0": {
"PayPal\\Service": "lib/",
"PayPal\\Types": "lib/"
After installing, Composer creates a file vendor/composer/autoload_namespaces.php with this content:
return array(
'PayPal\\Types' => array($vendorDir . '/paypal/adaptivepayments-sdk-php/lib', $vendorDir . '/paypal/adaptiveaccounts-sdk-php/lib'),
'PayPal\\Service' => array($vendorDir . '/paypal/adaptivepayments-sdk-php/lib', $vendorDir . '/paypal/adaptiveaccounts-sdk-php/lib'),
'PayPal' => array($vendorDir . '/paypal/sdk-core-php/lib'),
So both libraries are included here, and I have no doubt the autoloading will work.
You cannot really do something about the duplicate classes with different content. Did you open an issue on Github? Without making the developer team aware of this problem, it will never get solved.
As a hack, you could define a post-install and post-update script that deletes one of these files. See the composer documentation for more details. Composer accepts either any shell command, or a static call to a PHP class. I'd go with the shell command here.
