OmniJS bundle editor on iOS

What code editors are you using to edit OmniJS bundle files on iOS?

I have my script files stores in iCloud. Editing on the Mac is straightforward. On iOS, editing single file scripts works well with text editors. For bundle files, the editor apps I have tested give me a file format not recognized error, or they need to copy the files out of their location in iCloud making iterative tweaks cumbersome

Thanks,

I haven’t found it, yet.
