Thanks. Another customer reported this problem once, but so far it didn't occur on my own device. If you find a way to reproduce the issue reliably, please let me know!

It depends on the hardware you are using, but more recent iPads like the 3rd or 4th generation iPad should handle such a file without problems.

But, if the file has some very long lines, this could be problem. Especially, if it is a minified .js file.

Will be fixed in Textastic 4.3.

This problem will be fixed in Textastic 4.3. It was a bug in the Dropbox SDK.

Yes, that's why I'm going to be able to use libgit2. See my comment above:

There is a promising library called libgit2 which can be used on iOS due to their more permissive license. Currently, it's missing essential features like SSH transport, pull and push. Those guys are working on this. When libgit2 adds these features, I can add Git support to Textastic. I considered helping to add these features to libgit2 and read a lot of the code already, but unfortunately writing a low-level C Git library is not my area of expertise.

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]*)".
