that have overlapping ranges in the editor; also got rid of the id-set stuff Getting rid of the id-set information that was computed means that now the mouse-over green bubbles, the "jump to next binding occurrence"/ "jump to bound occurrence" keybindings/menu items, and the renaming are all being computed from the arrows information as needed, instead of building up sets as check syntax collects information. This may change the way Check Syntax behaves in some cases; so far the only example I've found has been strange and are arguably for the better. Specifically, this program (define-syntax-rule (m x) (λ (x) x)) (m z) no longer draws a green bubble when you mouse over the "z", since there are no arrows (the only arrow that might have been drawn is discarded since its start and end points are the same place). This speeds up the "analyze the expanded code" phase of check syntax, making it approximately 1.6x faster than before (going from about 31 seconds to about 19 seconds for this phase for the drracket/private/unit.rkt file (on my machine)). Also, the replay phase is probably a bit faster now, tho, too: there were 1.07x fewer elements to process in the trace that comes back from online check syntax now for that same file (33063 to 30842) Note that this is only that one phase: this doesn't count the time to actually expand the program (the dark blue bubble phase) nor the time to send the results between places, nor the time to replay the collected information (the light purple bubble phase). |

The Racket Programming Language =============================== Instructions for building Racket from source are in src/README. The main executables in this package: * DrRacket: Racket's integrated development environment (start here!). * racket: command-line tool for running Racket programs. * raco: command-line tool for compilation, documentation, and more. More Information ---------------- For Racket documentation, use DrRacket's `Help' menu, run the `Racket Documentation' application (Windows or Mac OS X), or run `raco docs' from a command line.
