[Cuis-dev] Saving StyledText.pck.st seems to corrupt it

[Bernhard Pieber]

Hi everyone,

When I load the StyledTextEditor in a updated image and save the StyledText.pck.st it seems to get corrupted. This is how it looks like in git diff:

I can reproduce it with these steps:

mkdir StyledTextEditor
cd StyledTextEditor
git clone --depth 1 https://github.com/Cuis-Smalltalk/Cuis-Smalltalk-Dev.git
curl -L -o squeak.cog.spur_macos64x64.dmg https://github.com/OpenSmalltalk/opensmalltalk-vm/releases/download/202206021410/squeak.cog.spur_macos64x64.dmg
Mount .dmg and copy Squeak.app to folder StyledTextEditor
git clone https://github.com/Cuis-Smalltalk/StyledTextEditor.git
git clone https://github.com/Cuis-Smalltalk/Morphic.git
./Squeak.app/Contents/MacOS/Squeak Cuis-Smalltalk-Dev/Cuis6.0-5686.image

In Cuis do:
ChangeSet installNewChanges.
Feature require: 'StyledText'.
Open > Installed Packages
Select StyledText 1.57.
Delete the description
Click save

Back in the terminal:
cd StyledTextEditor
git diff

When I save the package Compression 1.32 no such corruption seems to occur. Has anyone encountered this type of problem in some other package?

Cheers,
Bernhard
