Type info is not working correctly

[rvion]

I made a PR (https://github.com/lukexi/stack-ide-sublime/pull/7) that picked the right type info to show, but the feature doesn't seem to work anymore

Now

Before

Exemple 1 :

Example 2:

related code was:

   def filter_enclosing(_,from_col, to_col, from_line, to_line, spans):
       return [span for span in spans if 
           (   ((span[1].get("spanFromLine")<from_line) or 
               (span[1].get("spanFromLine") == from_line and
                span[1].get("spanFromColumn") <= from_col))
           and ((span[1].get("spanToLine")>to_line) or 
               (span[1].get("spanToLine") == to_line and
                span[1].get("spanToColumn") >= to_col))
           )]

[type_string, type_span] = self.filter_enclosing(
                from_col_+1, to_col_+1,
                from_line_+1, to_line_+1,
                types)[0]

Ah this is my bad.. I thought stack ide already considered the selection when returning results but seeing this it obviously doesn't. I'll restore the old logic shortly!

[tomv564]

Should be fixed, @rvion can you let me know otherwise? Thanks!

[rvion]

Wow, fast, thank you ! I'll reopen if it's not working :)

[rvion]

it doesn't seem to be working

[rvion]

the function filter_enclosing doens't seem to do the same thing as your modification

   def filter_enclosing(_,from_col, to_col, from_line, to_line, spans):
       return [span for span in spans if 
           (   ((span[1].get("spanFromLine")<from_line) or 
               (span[1].get("spanFromLine") == from_line and
                span[1].get("spanFromColumn") <= from_col))
           and ((span[1].get("spanToLine")>to_line) or 
               (span[1].get("spanToLine") == to_line and
                span[1].get("spanToColumn") >= to_col))
           )]

ping @tomv564

Can you make sure your Sublime is running the latest code?

The filter_enclosing function should work the same, but could also use some tests (and it wouldn't be the first time I misunderstood it!). Instead of comparing line and column together it translates everything to Region objects and compares those.

[rvion]

Yes, I'm running the latest code:

$ git log --pretty=oneline --abbrev-commit -5
10d0a28 Merge pull request #33 from tomv564/fix_reset_stackide

2630a43 Merge pull request #27 from tomv564/fix_selection_type_info
3f479aa fix show selection type functionality

but there is still a problem for me:

my guess is that we have a different version of either

• stack (stack --version: 0.1.7.0, Git revision 14236a4f1cb349fd0a6870a2a78bbe182dd9565a x86_64) (last version as of today)
• stack-ide (stack-ide --version: 0.1.0.0, Git revision 9d0e22e22bba2945f5d437490255c81a336d80ef (174 commits) X86_64)
• sublime-text:

[rvion]

just updated everything to the latests versions, and still have the problem:

Are you on linux ? I'm on mac, difference may be there:

$ uname -a

[rvion]

found the bug :)

/cc @tomv564

I have the automatic popup feature enabled:

And when I hover some code, the automatic type popup is wrong:

But when I hit Cmd+T (as you did to test the feature), it is correct

this is because in https://github.com/lukexi/stack-ide-sublime/blob/master/win.py#L43-L50, there is a duplicated code branch that is wrong:

        types = list(parse_exp_types(exp_types))
        if types:
            # Display the first type in a region and in the status bar
            view = self.window.active_view()
            (type, span) = types[0]
            if span:
                if Win.show_popup:
                    view.show_popup(type)

[rvion]

possible fix (but keeping two different code path) would be to change

win.py

    from utility import ..., filter_enclosing

    [...]

    def highlight_type(self, exp_types):
        """
        ide-backend gives us a wealth of type info for the cursor. We only use the first,
        most specific one for now, but it gives us the types all the way out to the topmost
        expression.
        """
        type_spans = list(parse_exp_types(exp_types))
        if type_spans:
            _view = self.window.active_view()
            _type = next(filter_enclosing(_view, _view.sel()[0], type_spans), None)
            if not _type is None:
                _view.set_status("type_at_cursor", _type)
                if Win.show_popup:
                    _view.show_popup(_type)

I'm not making the PR because above code still duplicates code already in ShowHsTypeAtCursorCommand

Ah good find! If I have time I can leave some hints about a fix later. I'm also on OS-X with similar installed software / packages so the problem was definitely with the code :)

[tomv564]

I think the suggested change looks good, if you don't have a chance to fix it then I can do up a PR later!
