Ionic/Cordova update platform config

030_update_platform_config.js

#!/usr/bin/env node

/** This hook updates platform configuration files based on preferences and config-file data defined in config.xml.
 Currently only the AndroidManifest.xml and IOS *-Info.plist file are supported.
 
 See http://stackoverflow.com/questions/28198983/ionic-cordova-add-intent-filter-using-config-xml

 Preferences:
 1.  Preferences defined outside of the platform element will apply to all platforms
 2.  Preferences defined inside a platform element will apply only to the specified platform
 3.  Platform preferences take precedence over common preferences
 4.  The preferenceMappingData object contains all of the possible custom preferences to date including the
 target file they belong to, parent element, and destination element or attribute

 Config Files
 1.  config-file elements MUST be defined inside a platform element, otherwise they will be ignored.
 2.  config-file target attributes specify the target file to update. (AndroidManifest.xml or *-Info.plist)
 3.  config-file parent attributes specify the parent element (AndroidManifest.xml) or parent key (*-Info.plist)
 that the child data will replace or be appended to.
 4.  config-file elements are uniquely indexed by target AND parent for each platform.
 5.  If there are multiple config-file's defined with the same target AND parent, the last config-file will be used
 6.  Elements defined WITHIN a config-file will replace or be appended to the same elements relative to the parent element
 7.  If a unique config-file contains multiples of the same elements (other than uses-permission elements which are
 selected by by the uses-permission name attribute), the last defined element will be retrieved.

 Examples:

 AndroidManifest.xml
 NOTE: For possible manifest values see http://developer.android.com/guide/topics/manifest/manifest-intro.html

 <platform name="android">
 //These preferences are actually available in Cordova by default although not currently documented
 <preference name="android-minSdkVersion" value="8" />
 <preference name="android-maxSdkVersion" value="19" />
 <preference name="android-targetSdkVersion" value="19" />

 //custom preferences examples
 <preference name="android-windowSoftInputMode" value="stateVisible" />
 <preference name="android-installLocation" value="auto" />
 <preference name="android-launchMode" value="singleTop" />
 <preference name="android-activity-hardwareAccelerated" value="false" />
 <preference name="android-manifest-hardwareAccelerated" value="false" />
 <preference name="android-configChanges" value="orientation" />
 <preference name="android-theme" value="@android:style/Theme.Black.NoTitleBar" />

 <config-file target="AndroidManifest.xml" parent="/*>
 <supports-screens
 android:xlargeScreens="false"
 android:largeScreens="false"
 android:smallScreens="false" />

 <uses-permission android:name="android.permission.READ_CONTACTS" android:maxSdkVersion="15" />
 <uses-permission android:name="android.permission.WRITE_CONTACTS" />
 </config-file>
 </platform>

 *-Info.plist

 <platform name="ios">
 <config-file platform="ios" target="*-Info.plist" parent="UISupportedInterfaceOrientations">
 <array>
 <string>UIInterfaceOrientationLandscapeOmg</string>
 </array>
 </config-file>

 <config-file platform="ios" target="*-Info.plist" parent="SomeOtherPlistKey">
 <string>someValue</string>
 </config-file>
 </platform>

 NOTE: Currently, items aren't removed from the platform config files if you remove them from config.xml.
 For example, if you add a custom permission, build the remove it, it will still be in the manifest.
 If you make a mistake, for example adding an element to the wrong parent, you may need to remove and add your platform,
 or revert to your previous manifest/plist file.

 TODO: We may need to capture all default manifest/plist elements/keys created by Cordova along with any plugin elements/keys to compare against custom elements to remove.

_.indexBy has been replaced by _.keyBy in lodash by the way

This is not working in Xcode8 + iOS10.
I am unable to find the exact bug, but the app doesn't start if this script is running and changing the plist file.
If I remove this script the app runs fine.

Also, the custom config that I am trying to add with this script, if I add the exact same value manually in the plist file via editor - the app works just fine.
I suspect something is wrong with respect to the Xcode8 !

@sur I think I may have the same issue. However it's not xCode, but how the script transforms the -info.plist file. For me it seems to be converting

<key>NSMainNibFile</key> <string/> <key>NSMainNibFile~ipad</key> <string/>

to

<key>NSMainNibFile</key> <string>NSMainNibFile~ipad</string>

Which crashed the app when you run it on the device. The issue is with plist@2.0.* (see issue: TooTallNate/plist.js#79). Workaround: Just roll back to use plist@1.2.0.

@halyburton Thanks for the hint! There seems to be something wrong with parsing ~ characters, but I got no idea where that comes from. In the end I just wrote a script to add my plist stuff to the platforms/ios/<project>/<project>-Info.plist file.

This hook helped me a lot though!

@marcocarnazzo this hook was very helpful, thank you! As others have noted I needed to change _.indexBy to _.keyBy in the getConfigFilesByTargetAndParent method. After that my plist is perfect, no more needing to edit manually!

+1 that this should be in repo so it can be edited and updated

I have changed the indexBy, added the element to the widget tag and removed entries in config.xml as suggested, but is still getting

Any other ideas

@ThorvaldAagaard your error is related to @AgDude's comment about error reporting. You're not seeing the original error. Change the code as per @AgDude's instructions and you will see the actual error.

My AndroidManifest xml not being modified 😢

This works for me but only after I make these changes, and noting some things that are somehow implicitly assumed

• needed to change _.indexBy => _.keyBy
• looks like this script is expected to be placed in the same location as config.xml. if you place this script in a folder that is not the same as the config.xml file you need to update the rootdir location
• @AgDude's suggestion is required, otherwise it won't work at all, stdout.write(e.toString() + '\n');

I only do ios build for now so can't verify for Android yet

I'm so sorry!
GitHub does not notify by about your comments.
I just edited this hook as you suggest (thank you!).
I also write something about re-use of this code (public domain: use it as you like!).

Just a note: I'm not using Ionic anymore so this code is unmantained.
Sorry again.
