rangeFormatting response is invalid #1074
Description
This uses the same test.json as issue #1073 (attached)
test.json.txt
Once the assertion_error in #1073 is fixed, the response to the rangeFormatting request is (formatted for readability):
[(:range
(:start (:line 0 :character 28)
:end (:line 0 :character 27))
:newText "\n")
(:range
(:start (:line 1 :character 0)
:end (:line 1 :character 0))
:newText " ")
(:range
(:start (:line 3 :character 15)
:end (:line 4 :character 0))
:newText " ")
(:range
(:start (:line 4 :character 2)
:end (:line 4 :character 3))
:newText "\n")
(:range
(:start (:line 5 :character 0)
:end (:line 5 :character 0))
:newText " ")]
The first range appears to violate https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#range; it specifies a region that starts at 28 and ends at 27 (exclusive), which is not possible. It appears that the edit is trying to insert a newline without deleting any text; if so, the range should be 28 .. 28.
The other ranges are ok. However, the overall formatting is very odd; there is a blank line in the with clause, and continuation lines are indented by 8. Ah - it appears to be using 'tabSize' as the base indent; changing that changes the indent accordingly. I'll submit a separate issue on this.
