indentations in computation expressions not working #300

Open ruffianeo opened 2 years ago

ruffianeo commented 2 years ago

Description

Statements in computation expressions, which should indent the following lines, but do not, include (those I found so far):

They seem to work outside computation expressions.

Repro steps

  1. use emacs in fsharp-mode and type the following (and be amazed by the non-indenting!):
    
    module issues

let indent_in_computation_expressions_not_working () = seq { for i = 0 to 10 do if i % 2 = 0 then yield "even" else yield "odd" }

2. in fsi (dotnet fsi): `#load "issues.fs"`
> #load "issue.fs";;  
[Loading /home/.../dev/fs/issue.fs]  
/home/.../dev/fs/issue.fs(8,9): warning FS0058: Possible incorrect indentation: this token is offside of context started at position (6:9). Try indenting this token further or using standard formatting conventions.  
/home/.../dev/fs/issue.fs(8,9): warning FS0058: Possible incorrect indentation: this token is offside of context  
 started at position (6:9). Try indenting this token further or using standard formatting conventions.  

### Expected behavior
The indenting should be right, but it is as shown above.

module issues

let indent_in_computation_expressions_not_working () = seq { for i = 0 to 10 do if i % 2 = 0 then yield "even" else yield "odd" }


### Actual behavior

module issues

let indent_in_computation_expressions_not_working () = seq { for i = 0 to 10 do if i % 2 = 0 then yield "even" else yield "odd" }



### Known workarounds

use C-c> to indent every line in such a block individually.
