# TODOs, notes, and various thoughts

## TODOs
 - [x] `=` and `\in` should be `in` in for loops
 - [x] Space after `,` in tuples, function calls, function definitions, `{}` etc.
 - [x] No leading/trailing space in tuples etc `( a, b )` -> `(a, b)`
 - [ ] Disallow putting kwargs before all positional args when calling functions
 - [ ] Space after `;` in named tuples, keyword arguments (callsite and definitions)
 - [x] Indentation
 - [ ] Trim trailing `;` togheter with ws.
 - [x] Whitespace in ternaries
 - [x] Parenteses around expressions in `:` operator (e.g. `1 + 2:3` -> `(1 + 2):3)`)


## Ideas

- Normalize `1.0e3` -> `1.0e+3`? Normalize `1.0e+3` -> `1.0e3`? Leave alone? I
  kinda thing it looks clearer with the `+` and for `-` it is necessary anyway
  so that would make it symmetric.

## Inconsistencies

- The `spaces_around_operators` rule have the following inconsistencies.

   - `:`, `^`, and `::` instead fall under `no_spaces_around_colon_etc`:
     ```julia
     # current formatting      # "consistent" formatting
     a:b                       a : b                            ✖
     a^b                       a ^ b                            ✖
     a::b                      a :: b                           ✖
     ```

   - `<:` and `<:` fall under `no_spaces_around_colon_etc` if they have no LHS:
     ```julia
     # current formatting      # "consistent" formatting
     a <: b                    a <: b                           ✔
     a >: b                    a >: b                           ✔
     a{c <: b}                 a{c <: b}                        ✔
     a{c >: b}                 a{c >: b}                        ✔
     a{<:b}                    a{<: b}                          ✖
     a{>:b}                    a{>: b}                          ✖
     ```

## Bad decisions?

 - Space around operators: if there are more, leave alone? This usualy indicate
   some kind of manual alignment. Perhaps we can align at `=` for connected
   siblings.
 - Trimming trailing 0 in floats messes up alignment sometimes.
