Anton (Apr 21 2026 at 09:27): Anton (Apr 21 2026 at 09:27):Can I make roc fmt add an empty line between the last line of the function implementation and the next doc comment?
So, this:
is_empty : Str -> Bool
is_empty = |str| Str.count_utf8_bytes(str) == 0
## Concatenates two strings together.
## ```roc
## expect "ab".concat("cd") == "abcd"
## expect "hello".concat("") == "hello"
## expect "".concat("") == ""
## ```
concat : Str, Str -> Str
## Determines whether or not the first Str contains the second.
## ```roc
## expect "foobarbaz".contains("bar")
## expect !"apple".contains("orange")
## expect "anything".contains("")
## ```
contains : Str, Str -> Bool
Becomes:
is_empty : Str -> Bool
is_empty = |str| Str.count_utf8_bytes(str) == 0
## Concatenates two strings together.
## ```roc
## expect "ab".concat("cd") == "abcd"
## expect "hello".concat("") == "hello"
## expect "".concat("") == ""
## ```
concat : Str, Str -> Str
## Determines whether or not the first Str contains the second.
## ```roc
## expect "foobarbaz".contains("bar")
## expect !"apple".contains("orange")
## expect "anything".contains("")
## ```
contains : Str, Str -> Bool
I like that -- but only when there is a doc comment.

Ian McLerran (May 07 2026 at 16:55):Just out of curiosity, why wouldn't we want a blank line between functions when there is NOT a doc comment? Do we really want:
is_empty : Str -> Bool
is_empty = |str| Str.count_utf8_bytes(str) == 0
concat : Str, Str -> Str
contains : Str, Str -> Bool
Instead of:
is_empty : Str -> Bool
is_empty = |str| Str.count_utf8_bytes(str) == 0
concat : Str, Str -> Str
contains : Str, Str -> Bool
yeah that sounds like a good change to me!
Anton (May 09 2026 at 08:44):I'll implement that right now
Anton (May 09 2026 at 12:49):Done in PR#9399
