wtfautolayout's Issues

Text not rendered correctly

First, thanks for this awesome tool!

There is a problem of formatting with the <code> tag. See:

I guess the translatesAutoresizingMaskIntoConstraints text should be in another font without the <code> tags?

The output is exactly what came out of Xcode, except that I replaced my app’s name with MyAppXYZ (a string of the same length).

file name with + sign shows syntax error

When a file name has + sign it shows a syntax error:

 
Line 3, Column 68
    "<SnapKit.LayoutConstraint:0x7feb4e8fa260@PViewController+Ext.swift#21 App_Debug.StackView:0x7feb4e8d58b0.leading == UILayoutGuide:0x7feb50d2aa70.leading + 10.0>",
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^
Expected: '#' in constraint instance.file location
Expected: file location in constraint instance

Removing the sign + fixes the error.

Make a Graphic Rendering

In addition to the list of constraints, draw rectangles properly depending on the given constraints to better visualize how the constraints interact.

Multiple permalinks for the same query

If you parse:

(
    "<NSLayoutConstraint:0x17468b860 progress background.height == 5   (active, names: progress background:0x1089a5290 )>"
)

and click "Permalink", it gives you this URL:

https://www.wtfautolayout.com/?constraintlog=%0A%0A%22%3CNSLayoutConstraint%3A0x17468b860%20progress%20background%2Eheight%20%3D%3D%205%20%20%20%28active%2C%20names%3A%20progress%20background%3A0x1089a5290%20%29%3E%22%0A%0A

and if you click "Permalink" again, it gives you this URL:

https://www.wtfautolayout.com/?constraintlog=%22%3CNSLayoutConstraint%3A0x17468b860%20progress%20background%2Eheight%20%3D%3D%205%20%20%20%28active%2C%20names%3A%20progress%20background%3A0x1089a5290%20%29%3E%22

It should either hide the button if the constraintlog parameter exists, either return the same value everytime for the same query.

Unexpected Input error for firstBaseline

The following results in an Unexpected Input error. Changing "firstBaseline" to "bottom" fixes the issue.

Incorrect parsing for named views

I set the accessibilityIdentifier for a UIView and the constraint error looks like this (trimmed):

(
    "<NSLayoutConstraint:0x17468b860 progress background.height == 5   (active, names: progress background:0x1089a5290 )>"
)

and it crashed with:

Preserve constraint identifiers

First off — thank you for making this site; it's invaluable in getting a parsable breakdown of constraint resolution errors!

Something I noticed is that constraint identifiers are completely lost in the output, which (if you are using them) is quite the loss. Keeping them in would help a lot in determining what constraints are being set where, belong to what groups, etc. etc.

(Thanks again!)

Custom naming of views

Instead of View1 or View2, it would be neat if we could change it to something easy to remember. Right now I have to write down the memory address of view1, launch the view debugger and cross reference the address from wtfautolayout to find out that view1 actually is CustomHeaderView. For a couple views its pretty easy, but gets difficult as more views are on the screen.

It would be nice to also parse `po view.constraints`

It has a similar output but a different style. I think it's not that hard to add this parsing option.

I created a regex that helps but not convenient - https://regex101.com/r/NkATVe/1

Also it is a problem with 4-th expression where used priorities.

Expanded message for `UIView-Encapsulated-Layout` constraints

UIView-Encapsulated-Layout-* constraints are commonly added by collection views et al, but are also the resultant constraints from translatesAutoresizingMaskIntoConstraints. In projects where constraints are being added to old frame-based layouts, knowing this can be really helpful.
