The module is renamed to `Mark`, and functions renamed to avoid redundancy:
`Marked.mark` is now `Mark.add`
`Marked.unmark` is now `Mark.remove`
`Marked.map_under_mark` is now simply `Mark.map`
etc.
`Marked.same_mark_as` is replaced by `Mark.copy`, but with the arguments
swapped (which seemed more convenient throughout)
Since a type `Mark.t` would indicate a mark, and to avoid confusion, the type
`Marked.t` is renamed to `Mark.ed` as a shorthand for `Mark.marked` ; this part
can easily be removed if that's too much quirkiness.
- Fix the printer for scopes
- Improve the printer for struct types
- Remove `Print.expr'`. Use `Expr.format` as the function with simplified arguments instead.
- `Print.expr` no longer needs the context
- This removes the need for `expr ~debug` + `expr_debug` ;
use `Print.expr` for normal (non-debug) output,
and `Print.expr' ?debug ()` for possibly debug output.
- This improves consistency of debug expr output in many places
- Prints simplified operators (without type suffix) in non-verbose mode
(this patch also fixes some cases of `Expr.skip_wrappers` and leverages the
binder equality provided by Bindlib)
Note that there were significant differences between the two printers (see the test diff!). Overall the `dcalc` one seemed newer so that's what I took, with only the required additions from `lcalc` (exceptions, raise and catch)
this patch is just a bunch of `sed` commands
```shell
cd compiler
sed -i 's/Pos.marked/Marked.pos/g' *.ml* **/*.ml*
sed -i 's/Pos.unmark/Marked.unmark/g' *.ml* **/*.ml*
sed -i 's/Pos\.get_position/Marked.get_mark/g' *.ml* **/*.ml*
sed -i 's/Pos\.same_pos_as/Marked.same_mark_as/g' *.ml* **/*.ml*
sed -i 's/Pos\.map_under_mark/Marked.map_under_mark/g' *.ml* **/*.ml*
sed -i 's/Pos\.mark/Marked.mark/g' *.ml* **/*.ml*
sed -i 's/Pos\.compare_marked/Marked.compare/g' *.ml* **/*.ml*
```
This avoids many intermediate calls to e.g. `Format.asprintf`; should result in
some cases in "more correct" use of `Format`¹, avoid the computation of unused
debug strings, and make the code more readable.
¹ for `Format` to work as expected, all intermediate calls need to go through
it. Some cases of formatting to an intermediate string then printing through Format
again are still present, but this makes the situation better.
