How to load plain SQL into database with Ecto 2018-08-16 ecto.load works fine. mix ecto.load -d "data.sql" How to use Parcel with Phoenix framework 1.3 2018-08-12 I like Parcel bundler which is zero configuration web app bundler tool. I’ll show you how to use Parcel bundler on Phoenix framework 1.3. Create a phoenix project mix phx.new your_project cd your_project It installs brunch. But it’s easier to let it install brunch. Because there will be package.json and directories. Update assets/package.json Then let’s configure package.json . It’s under assets directory. You can replace it to like this. { "repository": {}, "license": "MIT", "scripts": { "deploy": "parcel build js/app.js --out-dir ../priv/static/assets", }, "dependencies": { "phoenix": "file:../deps/phoenix", "phoenix_html": "file:../deps/phoenix_html" }, "devDependencies": { "parcel-bundler": "^1.9.7" } } Then yarn . Actually, I’m not sure if I need to set scripts here. Because there is a setting section in config/dev.exs . Update config/dev.exs In config/dev.exs , you will find Endpoint config. Update watchers like this. This will be ran when you run phoenix. config :your_project, YourProject.Endpoint, http: [port: 4000], debug_errors: true, code_reloader: true, check_origin: false, watchers: [node: ["node_modules/parcel-bundler/bin/cli.js", "watch", "js/app.js", "--out-dir", "../priv/static/assets", cd: Path.expand("../assets", __DIR__)]] Update lib/your_project_web/endpoint.ex In lib/your_project_web/endpoint.ex , you will find Plug.Static config. Add assets directory. Then phx.server serves files under priv/static/assets directory. plug Plug.Static, at: "/", from: :vegan, gzip: false, only: ~w(assets favicon.ico robots.txt) Start phoenix server iex -S mix phx.server Then you will see a compiled JavaScript file at priv/static/js which you configured in dev.exs . Cleanup OSX ~/Library/Developer/ 2018-05-31 ~/Library/Developer/ is getting fatter and fatter. Even after Xcode is updated, there still are old iOS images and Core simulators. I’ll show you what and how you can delete these files. Delete old archives You can delete old Archives, under this directory: ~/Library/Developer/Xcode/Archives/ Delete old CoreSimulators There are many olc CoreSimulator devices under ~/Library/Developer/CoreSimulator/Devices You can run this to delete these devices. xcrun simctl delete unavailable Delete old iOS DeviceSupports There are many old iOS DeviceSupport under this directory. You can delete old iOS versions of directories. ~/Library/Developer/Xcode/iOS DeviceSupport Use NTP on AWS 2018-03-15 Set NTP server to 169.254.169.123 IP Address. Then you don’t need to setup any security groups or routes for that. For Ubuntu 16.04, modifying /etc/systemd/timesyncd.conf like this would work. [Time] NTP=169.254.169.123 FallbackNTP= Setting the Time for Your Linux Instance How to make new phoenix project with MySQL 2018-01-09 phx.new commands with MySQL, without Brunch, without HTML mix phx.new awesome_project --no-html --no-brunch --database mysql How to add programs to rcX.d on Raspbian 2017-08-29 How to autostart programs on Raspbian. (Raspberry Pi) For example, how to enable/disable mysql-server. Enable autostarting. $ sudo insserv -d mysql Disable autostarting. $ sudo insserv -r mysql Change key repeat interval on OSX 2016-11-06 We can change the intervals of key repeat and delay until repeat at the System preferences > Keyboard. But you may think it too slow even if you set the minimum values. We can set faster value with Karabiner . Or we can set it at a Terminal. My recommendation is following :) $ defaults write NSGlobalDomain KeyRepeat -int 1 $ defaults write NSGlobalDomain InitialKeyRepeat -int 12 First one is the repeat interval when you keep pressing a key. Second is delay until starting to repeat. 1 is not milliseconds. I’m not sure about the value, but maybe 1 is equivalent to 16 milliseconds. So the config will get you KeyRepeat -> 16ms, Delay until repeat -> 200ms. If it doesn’t work, try following. (try true and false ) $ defaults write NSGlobalDomain ApplePressAndHoldEnabled -bool false How to use DynamoDB Local on CircleCI 2016-10-05 We can use DynamoDB Local on our local machines. Also we can use it on CircleCI. All you have to do is put configurations to circle.yml circle.yml example This is an example for testing Rails application. machine: timezone: Asia/Tokyo ruby: version: 2.3.1 java: version: openjdk7 environment: DYNAMODB_ENDPOINT: http://localhost:8456 database: override: - cp config/database.yml.ci config/database.yml - bundle exec rake db:create db:migrate dependencies: cache_directories: - "~/DynamoDBLocal" post: - "[ -d ~/DynamoDBLocal ] || (mkdir ~/DynamoDBLocal; cd ~/DynamoDBLocal; curl -s -L http://dynamodb-local.s3-website-us-west-2.amazonaws.com/dynamodb_local_latest.tar.gz | tar xz)" - "java -Xms1024m -Xmx1024m -Djava.library.path=~/DynamoDBLocal/DynamoDBLocal_lib -jar ~/DynamoDBLocal/DynamoDBLocal.jar --port 8456": background: true xcodeproj を CONFLICT しづらくする mergepbx 2016-09-30 Xcode を使って開発していると、 .xcodeproj が、論理的には CONFLICT していないのに Xcodeのバージョンアップ等で激しく CONFLICT することがある。 mergepbx を使うと、理不尽に CONFLICT ã•ã‚Œã‚‹ã‚±ãƒ¼ã‚¹ã‚’ã‚ã‚‹ç¨‹åº¦è§£æ¶ˆã—ã¦ãã‚Œã‚‹ã€‚è¤‡æ•°äººã§é–‹ç™ºã—ã¦ã„ã‚‹æ™‚ã¯å ¥ã‚Œã¦ãŠã„ã¦åŠ©ã‹ã‚‹ã“ã¨ãŒå¤šã„ã€‚ 1年くらい使ってるけど、特に問題が起きたことはないです :-) Install brew install mergepbx Usage 以下の2ファイルに設定を追記(プロジェクト単位でもglobalでもOK)すれば、あとは git merge や git rebase とか通常の操作で mergepbx を使ってくれるようになります。 .gitconfig ä¸‹è¨˜ã‚’è¿½åŠ ã€‚ [merge "mergepbx"] name = Xcode project files merger driver = mergepbx %O %A %B .gitattributes ä¸‹è¨˜ã‚’è¿½åŠ ã€‚ *.pbxproj merge=mergepbx How to change webpack config between envirionments 2016-09-23 How to change webpack config between environments? When using React, the document says we have to set environment variable NODE_ENV to production . And I also want to use UglifyJsPlugin only on production build. Note: by default, React will be in development mode. To use React in production mode, set the environment variable NODE_ENV to production (using envify or webpack’s DefinePlugin). A minifier that performs dead-code elimination such as UglifyJS is recommended to completely remove the extra code present in development mode. https://facebook.github.io/react/downloads.html Use process.env.NODE_ENV I found a good example :-) webpack issues#868 Then I can switch config using process.env.NODE_ENV . Example This is simple webpack.config.js to use React with ES2015. Use Then you can use like these on development ./node_modules/webpack/bin/webpack.js --watch -d --progress --color on production build NODE_ENV=production ./node_modules/webpack/bin/webpack.js --progress --color Rename an instance of AWS API Gateway 2016-09-01 Rename API Gateway I can rename only by using aws cli. aws apigateway update-rest-api --rest-api-id IDOfTheAPIThatNeedsTobeUpdated --patch-operations op=replace,path=/name,value=NewName Ref: http://stackoverflow.com/questions/34337340/how-to-rename-an-aws-api-gateway-api-instance ## TTTAttributedLabelでUILabelの一部をリンクにする 2016-04-15 「 利用規約 に同意してログインする」的な UILabel で、タップしたら遷移するようにする。 TTTAttributedLabel を使う。 Podfile に TTTAttributedLabel ã‚’è¿½åŠ # Podfile pod 'TTTAttributedLabel' InterfaceBuilder UILabel ã‚’é ç½®ã™ã‚‹ã®ã¨åŒã˜ã‚ˆã†ã«ã€é©å½“ã«é ç½®ã™ã‚‹ã€‚Class を、 TTTAttributedLabel にしておく。 Linkをコードで設定する var label : TTTAttributedLabel! 的なプロパティが設定してあるという前提で、文字列は「利用規約に同意してログインする」になってるとします。 Lin...
