Re: [Pharo-users] SLICE-Issue-18901-Highlight-message-send-selector-on-mouse-over-NicolaiHess.4 introduces new bug?

[Nicolai Hess]

Hi Alistair,
the error messages from Rubric-Components, if there occured an error is
often misleading.

I added this act-on-move-functionality for highlighting message sends and I
forgot to respect to full TextAction hierarchy
(I only implemented the
actOnMove: anEvent for: target in: aParagraph editor: anEditor
method for TextLink and TextMethodLink and not for TextAction)

You can solve this by moving the implementation
actOnMove: anEvent for: target in: aParagraph editor: anEditor
"override in subclasses"
^ false

from TextLink, up to TextAction.

^ this. 
as Cyril says, win 64bits vm is still not ready (and it will take some more 
time to be).

[Pharo-users] SLICE-Issue-18901-Highlight-message-send-selector-on-mouse-over-NicolaiHess.4 introduces new bug?

[Alistair Grant]

Hi All,

I'm attempting to port some code that works in Pharo 5 to Pharo 6 and
have hit a problem when attempting to inspect text.

Inspecting the following:


| text |

text := Text fromString: 'Hello World'.
text addAttribute: (TextAction new actOnClickBlock: [ self halt ])
from: 1 to: 5.
text.


And then moving the mouse over the text causes the traceback
included below in Pharo 6, but is fine in Pharo 5.

I think the problem was introduced as part of
SLICE-Issue-18901-Highlight-message-send-selector-on-mouse-over-NicolaiHess.4
in RubAbstractTextArea>>mouseMove: where the line:

   self paragraph move: evt for: model controller: self editor.

was added to the start of the method.

I'm not familiar with this code, so it would be great if someone
(Nicolai? :-)) who has a better understanding of the original intention
can offer a suggested fix.

Removing the addition appears to resolve the problem, although I expect
it introduces other unwanted side effects, and the remainder of the
method was also refactored.

Thanks!
Alistair

I extracted it here:

https://github.com/DuneSt/MaterialColors

In the future I would like to add some utilities methods for example to
choose the font color from the background color following MaterialDesign
recommendations. Like that we would not have to care about the
readability of a font color if the background changes. (Following
https://material.io/guidelines/style/color.html#color-color-schemes)
