Revset syntax error on .^::

[francois]

According to sl help revset:

"x::y"
 A DAG range, meaning all commits that are descendants of x and ancestors
 of y, including x and y themselves. If the first endpoint is left out,
 this is equivalent to "ancestors(y)", if the second is left out it is
 equivalent to "descendants(x)".

I wanted to rebase the two topmost commits back onto master. I expected the revset .^:: to be equivalent to "parent + self". Instead, I received a syntax error (I used log here, but I had the same error with rebase):

╰─○ sl log -r '.^::'
sl: parse error at 4: not a prefix: end
(.^::
     ^ here)

I tried to surround :: with spaces, but I had the same syntax error. The only way not to have a syntax error was to use the revset .^::..

• For your rebase use case, you can use sl rebase -s .^ -d master to achieve that.

sl: parse error at 4: not a prefix: end

For the parser error, seems a bug in the parser, it treats ^ as infix expr and :: as its right operand. I will dive into the issue next week.
