[Cuis-dev] Possible normalization of code files to use ANSI assignment. Re: New handling of assignment and return arrows

[Juan Vuletich]

Hi Folks,

This is finally here.

With the attach, files and clipboard will always use '^' and ':='. When 
entering code, you can use '_' or ':=', and '^' as usual.

What you see in the display is controlled by a single preference that 
affects all code (the one you are typing and all the code in the 
system). Options are:
- All assignments and returns are ANSI: ':=' and '^'. This is, you see 
what is stored in code files.
- All assignments and returns are in Smalltalk-80 style: LeftArrow and 
UpArrow.

There's no need to convert existing files. Code files including '_' for 
assignment are still valid for reading.

Please try the attach, and give feedback. If we reach consensus, I'll 
push it to GitHub.

Thanks,
