Description
This interpretive production was created from archival footage of Eric Bier, PARC research scientist, demonstrating the Cedar integrated environment and programming language on January 24, 2019. Cedar was an evolution of the Mesa environment/language, developed at PARC’s Computer Science Laboratory originally for the Xerox Alto. Mesa was modular and strongly-typed, and influenced the later Modula family of languages. Cedar/Mesa ran on the D-machine successors to the Alto (such as the Dorado) and added features including garbage collection, and was later ported to Sun workstations. Cedar/Mesa’s integrated environment featured a graphical window system and a text editor, Tioga, which could be used for both programming and document preparation, allowing for fonts, styles, and graphics to be embedded in code files. The editor and all its commands were also available everywhere, including on the command console and in text fields. The demo itself is running through a Mac laptop remotely logged into Bier’s Sun workstation at PARC using X Windows. Bier demonstrates the Cedar development environment, Tioga editor, editing commands using three mouse buttons, sophisticated text search features, the command line, and the Gargoyle graphics editor, which was developed as part of Bier’s UC Berkeley Ph.D. dissertation. Bier is joined by Nick Briggs, Chris Jacobi, and Paul McJones.
