Nicer REPL for GNU Smalltalk

In the screenshots below:

• [107402]> is a REPL prompt showing connection ID
• I is an alias for an instance of MyInspector class
• s: aString on its own means "search for" or "show" (selectors that match the string)
• c: aClass on its own means "show class"
• The two above (s: and c:) together mean "show methods of a class that match the string"

It's also possible to display doctring for methods without printing the source code:

Notes

• FileStream class>>#popen:dir: accepts 'w+' for read-write communication

[19189]> p := (FileStream popen: '/bin/cat' dir: 'w+')
<Pipe on /bin/cat>
[19189]> p nextPutAll: ('asdasdasd',String nl)
'asdasdasd
'
[19189]> p nextLine
'asdasdasd'
[19189]> die
nil
[19189]> p close
<Pipe on /bin/cat>
[19189]> p close
<Pipe on /bin/cat>
[19189]> p
<Pipe on /bin/cat>
[19189]> p isOpen
false

TODO

• browse senders - RBBracketedParser on methodSourceString ~/portless/versions/smalltalk/gnu-smalltalk-git/packages/stinst/parser/RBParser.st

• allSelectors - better display, filtering, source code

• http://www.educery.com/papers/modules/

• deep into pharo - exceptions and blocks

• smalltalk/x - minidebugger is better there

• smalltalk/x - has --repl !

• remove wildcard accessor generation (where not needed)

• improve fileIn - parsing

DONE

• string - visible width / without invisible escape sequences / String subclass: ColorizedString

• make #subclass: msg sends clear the methods in the subclass

• diff after loading / after parsing - check if there's a need to remove methods

• inspector help

• track variables in evals - create a class and object for each player ~/portless/versions/smalltalk/gnu-smalltalk-git/packages/visualgst/WorkspaceVariableTracker.st

• DirPackage investigation
