QtQuick Rapid Prototyping with Terrarium

Write QML Everywhere, See Result Instantly

Get It on Google Play

Terrarium is now available on Google Play! And you can find it for Mac OSX or Ubuntu Linux (amd64 / i386) too! Please refer to the install section on project website.

Notes on Publish QML App to Google Play

Build your code normally with qmake && make, install it to a destination, say, android-terrarium:

make install INSTALL_ROOT=../android-terrarium

Pack and sign the APK by androiddeployqt command:

~/Qt5/5.3/android_armv7/bin/androiddeployqt --input android-libTerrarium.so-deployment-settings.json --output ../android-terrarium --release --sign ../TerrariumApp.keystore TerrariumApp

Here's the catch:

• There's a ANDROID_DEPLOYMENT_DEPENDENCIES variable for qmake profile, here's my reference
• androiddeployqt invokes SDK tools and changes project name to "QtApp" every time, that also overwritten build.xml. I fixed it by using a script workaround..
• Default AndroidManifest located at Qt5/5.3/android_armv7/src/android/java/AndroidManifest.xml, things you must change are package name, android:icon, uses-permission and uses-feature. Please refer to file on Github

Let's write QML everywhere!

使用 Terrarium 作 QML 快速原型開發

隨時隨地．立竿見影

聽說現在寫標題流行用 Apple 體, 我們也亂寫一個 XD

Google Play 下載

沒錯, Terrarium 上架 Google Play 啦! 另外還有 Mac 版 及 Ubuntu Linux 版 (amd64 / i386) 可以下載! 詳情請見網站連結.

發佈 Qt App 到 Google Play 的方法和心得

用冷門方案打包 apk 本來就吃力不討好, 加上不用 Eclipse 或 Qt Creator 全部手動, 可以採的雷我幾乎全踩過一遍了..

總之一般理論上來說的方法是先 qmake && make 完後指定安裝路徑, 比如說

make install INSTALL_ROOT=../android-terrarium

接著用 androiddeployqt 這個工具打包 apk:

~/Qt5/5.3/android_armv7/bin/androiddeployqt --input android-libTerrarium.so-deployment-settings.json --output ../android-terrarium --release --sign ../TerrariumApp.keystore TerrariumApp

但是有幾點要特別注意:

• qmake profile 有一個 ANDROID_DEPLOYMENT_DEPENDENCIES 變數可以用, 但會 override 原本內容, 所以要寫就得寫齊所有要用的 lib, 可以參考這邊寫法
• androiddeployqt 不知道哪裡想不開, 會自己呼叫 SDK tools 把 project name 改成 "QtApp", 難怪改 build.xml 都沒用除非手動 ant release 再 jarsigner / zipalign. 我是寫 script 去 workaround 它..
• 預設的 AndroidManifest 在 Qt5/5.3/android_armv7/src/android/java/AndroidManifest.xml, 其中必改的內容有 package name, android:icon 和 uses-permission 及 uses-feature. 這部份就參考 Github 上的檔案 吧

大概是這樣, 總之繼續往上架之路努力..這兩天包了快十個平台不同格式的套件 XD

最後送大家一張「隨時隨地寫 QML」的照片, 哪天想不開就放網站當 landing page 吧!

Terrarium.app - Live QML Editor and Viewer

Today we're excited to announce our latest open source project:

Project website: http://www.terrariumapp.com/

Terrarium is a cross platform QML playground, the view changes lively as you type in the editor, makes prototyping and experimenting with QtQuick a lot more fun!

We have already ported Terrarium to Ubuntu desktop and tablet, Mac OSX, iOS, and will be available in Apple App Store and Google Play as a free download soon.

If you have any idea or question, please feel free to write me a mail, ping me on twitter or send a PR on github, happy hacking!

小玩具 QML Playgrounds

最近隨著 Apple 於 WWDC 發表 Swift 以及附帶的 Xcode 6 Playgrounds 環境, 不但 Swift 主要開發者 Chris Lattner 公開表示受到 Learnable Programming 概念與 Light Table 專案的啟發, Bret Victor 在 2012 年那場知名的演講 Inventing on Principle 又再度引起熱烈討論.

由於之前已經發表過使用 QFileSystemWatcher 監控檔案變化而動態更新 view 的 QML LiveReload 工具; 趁著此波熱議, 花了一個下午做出了 QML 版的 Playgrounds, 原始碼在 Github 上: playgrounds.qml.

目前很簡單的使用 TextEdit 元件 (搭配 Atom Theme 配色), 在內容有修改時觸發 QHttpServer 送出更新過的 source. Loader 本身只負責把 cache 清掉重讀而已. 若要繼續做其他深入功能, 可能得遍歷所有 QObject 的 properties, 並搭配型別顯示不同的控制項.. 往好處想, 至少 syntax highlight 不難做就是了. XD

更新: 在 iOS 上跑也是沒問題的, 科科.
