📖Glamorous Toolkit Live #1: Moldable development & a tour

GT is written in Pharo (Smalltalk)

GT started as an object inspector and code editing tool was the very last thing they implemented (30:00)

29:00 for moldable development to be economically feasible, the cost of the custom tool must be very-very small

• average view method in GT is ~11 lines long

34:00 software design issue vs tool issue → Design issue vs tool issue

• e.g., big method vs small method. Small methods make you keep more context in the head (what other functions are doing) but a development tool can show other methods inline, so you don’t have to this issue

36:45 re: language workbenches

44:00 GT has built their own graphical stack

• skia

49:00 an example of pulling an html blog post and GT can execute smalltalk embedded in the page (by user command). the result is inserted in the page and is inspectable

51:00 Fleenk is self-funded by consulting

• legacy systems projects

• startups (aggressive prototyping)

56:00 design decisions

• focusing on reading aspect of programming

• treating environment as a language

• very expressive graphical stack

1:09:00 (use parsers to build AST for existing languages)

1:09:00 parsers debugger / simulator

1:10:00 “smalltalk is not a language but implementation of a language”

1:17:50 starting with a very concrete problem, not a generic one
