I thought for a few minutes about how you might achieve this in TxMt and then realised I didn't have the first clue. I tried recording a macro but of course it would only work for the simple case, as soon as I did: [...] it broke.
Can this (and/or the inverse) be done with a simple recordable macro?
Yes -- the trick is to use a regexp replacement.
It's a complex expression though, if you search for: ^([\s&&[^\n]]*) (.*?)\s*(?:{\s*(|[^|]+|)\s*(.*?)\s*}|do\s*(|[^|]+|)\s*(\S.*$) \s*end)
It'll find both types of blocks, and put the stuff in captures. Then do replace all in selection with this format string: $1$2(?3: do $3\n $1 $4\n$1end: { $5 $6 })
The (?3:…) part does a conditional replacement, based on whether capture 3 matches or not (which depends on the type of block-style we matched.
I recorded the macro myself and attached below. Save the file to e.g. Ruby.tmbundle/Macros -- it's bound to ctrl-shift-B by default (with scope source.ruby). I can add it to the default bundle, if this is of general use.
