Can you send me the .json file to support@textasticapp.com so I can have a look at it and try to make it work?

This is a JSON file, so you need to escape the regular expression string:

If your regular expression contains one backslash "\", it needs to be encoded for JSON like this "\\".

So, if your regular expression starts with two backslashes, you need to actually put four backslashes in the json file: "\\\\([a-z]*)".

Textastic uses the Oniguruma regex engine like TextMate.

Here's how Textastic checks whether it needs to display code completions:

• First, it looks if the scope at the cursor matches the scope selector of a code completion context (this is the "scope" element in a context) - you can show the current scope in Textastic by tapping in the editor with three fingers. It's probably easier to use TextMate on a Mac though.
  
• If the scope selector matches, Textastic tries to match the regular expression in the "pattern" backwards from the cursor position
• If the regular expression matches, it will uses the capture defined by the "completionCaptureIndex" as a prefix for the strings referenced by the "completionSetNames" array
• It will show all strings from the completionSet that have the prefix found in the previous step

No, sorry, I think editing binary files is out of the scope of a text editor.

I would recommend renaming it to yourfile.plist afterwards in order to get proper syntax highlighting.

I see. Your file is not a text file, but a binary plist file. You need to convert it to XML format to be able to edit it in a text editor like Textastic. You can do that on the command line on your Mac:

plutil -convert xml1 yourfile.strings

Did you try to tap on it? What happened?

Which encoding does the file have? .strings file are often UTF-16 files. Maybe your file doesn't have a proper Byte Order Mark (BOM). You could try to tap-and-hold the file, choose "Open with Encoding" and select UTF-16. Does that work?

Binary files are greyed out. You can tap on it anyway and try to open it, but if it is not a proper text file, it probably won't open.

What you can do is the following:

- Download the site to a folder

- Create a copy of that folder which serves as your backup
