I'm not sure if I understand you correctly, but maybe this is the info you are looking for:

If you want to create a new code completion definition, you can put the .json file in the local "#Textastic/CodeCompletion" folder. Textastic will pick up the changes at application startup time, so you have to manually quit the app. 

The combination of "scope" and "pattern" defines where code completion are shown.

You can generate a uuid on the Mac command line with this command:

uuidgen

Each completion file needs its own uuid to identify the file uniquely in the system and to make it load correctly.

The "completionSets" array defines a list of completion strings and gives them a name.

The "contexts" array at bottom of a completion file defines where the completion strings should be shown. This is the linkage point of the language file and the completion file:

The "scope" and the "pattern" work together: "scope" is a scope selector like "source.objc - comment - string" (see http://manual.macromates.com/en/scope_selectors). It must match the scope at the cursor.

"pattern" is a regular expression. It must also match backwards at the cursor position. 

The "completionCaptureIndex" defines which capture of the "pattern" will be used as the string to complete. 

The "completionSetNames" array defines which completion sets should be consulted for code completion in this context.

I hope this helps.

Textastic only uses the syntax definitions in the "Languages" folder of a TextMate bundle and some settings from the "Preferences" folder.

For code completion, it uses its own format: https://github.com/blach/Textastic-Customization - you can find the built-in definitions in the CodeCompletion directory.

iCloud backup already backs up the files in Textastic.

But, I'm currently working on a Mac app and iCloud support in the iOS apps.

Which connection settings do you use when you get this error?

Nebulous Lite is the ad-supported version of the $4,99 app Nebulous Notes. Sync is not easy to implement. If someone decides to offer a thing that is hard to implement in an ad-supported app for free, it doesn't make it easy to implement...

You can use the "Report a problem" link on your iTunes receipt to ask the iTunes team for a refund.

Sorry, but I have no plans for an Android version of Textastic.

Hallo, was genau ist die Frage? 

Textastic unterstützt Syntax-Highlighting für C und Java. Eine Liste der unterstützten Sprachen gibt es unter http://www.textasticapp.com/v4/manual/lessons/Which_file_types_are_supported.html
