Request: Is it possible to conceal before and after the effected values?

[sethwoodworth]

There are a number of math.foo functions that wrap the values they operate on that I would like to be considered for vim-cute-python:

     | a |        math.abs(a)         Absolute Value
    ⌊ a ⌋      math.floor(a)        Floor (although ⌊a was used in APL as the floor operator)
    ⌈ a ⌉      math.ceiling(a)     Ceiling

Two questions:

1. Is it possible to use vim's conceal to change things before and after a value?
2. Are you interested in adding these to vim-cute-python?

Hi,

As far as I know this is not easily doable since it's not possible to specify a conceal character for each end of of concealed region. I guess it would be possible by matching e.g. “math.abs(” and also using look-behind to conceal “)” when it follows “math.abs(” and an argument, but I don't think this is possible to do in a good way. (For example, one cannot match parentheses with a regex pattern.)

I would love to get a patch if this is possible to do in a not-super-hackish way, though. :-)
