Module Merlin_analysis.Destruct
Source
Destruct at the moment works in two contexts:
- an expression context: It will replace the expression
e
under the cursor with
match e with
| p1 -> _
| ...
This matching will be exhaustive.
If e
has a "package" type, it will be replaced by let module M = (val e) in _
- a pattern context: Here two different behaviors can be observed:
- if your matching is not exhaustive, it will be made exhaustive.
- if your matching is exhaustive, it will refine the subpattern under the cursor if possible (i.e. if your cursor is on a variable or _ ).
* * *
Final remarks:
- Destruct will refuse to work on expression (resp. patterns) with a functional or polymorphic type.
- Constructors of variant types will be prefixed by their path (if necessary) but record labels will not. The reason is that we don't control the way things are printed, we reuse
Pprintast
which will print things like:{ Module.label1 = label1 ; Module.label2 = label2}
where one would rather have{ Module.label1 ; label2 }
. Since qualifying one label is less annoying than rewriting the whole pattern, we decided to note qualify labels (understanding that the code inserted by merlin in the buffer will sometimes be wrong).
