Re: [racket-dev] P4P: A Syntax Proposal
Infix notation can be achieved unambiguously if you use LL(1) with
backtracking
...which I didn't want to do.
Pedagogically, it has been immensely valuable to explain to kids that
+ and - aren't some special thing, but are just mere operators -- and
so are string-append and image-overlay and so on.
Plus, there isn't much arithmetic in many Scheme programs, which means
the quantity of actual infix is small.
Infix goes beyond just arithmetic, ruby allows this sort of syntax
some_list.map{...}.filter{...}.map{...}.fold_right{...}
Which I find much more readable than
(fold-right (map (filter (map some_list)))

When I'm answering such questions, it is getting extremely difficult to tell people what to do, and often leads to some confusingly broken dialog.

Eli helped me write a module that installs a compile manager which compiles all loaded files on the fly. $ cat compile.rkt #lang racket/base (require compiler/cm) (current-load/use-compiled (make-compilation-manager-load/use-compiled-handler)) $ racket -t compile.rkt -l racket/base -t somefile.rkt ... $ ls compiled somefile_rkt.dep somefile_rkt.zo Any dependancies of 'somefile.rkt' would have been compiled as well.

Re: [racket-dev] try the GRacket2 branch
Maybe I screwed something up but I can't tell if I'm running gr2 or not. I built the gr2 branch and ran drscheme but so far it looks exactly the same as gr1 (which I am positive is actually gr1). Is there an easy way to tell if I'm running gr2? Or should gr2 look identical to gr1? On 10/28/2010 12:25 AM, Matthew Flatt wrote: The git repository now includes a gr2 branch for the new implementation of `racket/gui', which we've been informally calling GRacket2. The new `racket/gui' is intended to be mostly compatible with the current library, but there are some significant incompatibilities. Those differences are described below in a copy of the Porting from v5.0.x to vX.Y notes that are linked from the Release Notes page of the documentation. GRacket2 is a misnomer in the sense that you can use the new `racket/gui' with just `racket'. Furthermore, the drawing layer is mostly unbundled from the GUI layer into a separate `racket/draw' library, so you can manipulate images without a GUI (e.g., without an X11 connection). The documentation doesn't yet reflect the GUI--Draw split, Slideshow's pict library doesn't yet use `racket/draw', etc., but I hope to get to that next. More immediately, it's time for you to try out the gr2 branch for everyday work. I've switched to GRacket2 for SirMail, Slideshow, and DrRacket --- even during lecture. All library functionality is in place, but I'm sure that gaps and problems will show up as we put the library to work (and I know that some of the tests still fail). I expect to see many bug reports; once the bug reports slow down, I'll take that as a sign that GRacket2 can move to master branch. GRacket, Racket, Drawing, and GUIs -- Version X.Y includes two major changes to the Racket drawing and GUI API: * The drawing portion of the GUI toolbox is now available as a separate layer: `racket/draw'. This layer can be used independent of the `racket/gui/base' library, although `racket/gui' re-exports `racket/draw'. (The `racket/draw' library is built on top of the widely used Cairo drawing library and Pango text-rendering library.) * The GRacket executable is no longer strictly necessary for running GUI programs; the `racket/gui/base' library can be used from Racket. The GRacket executable still offers some additional GUI-specific functiontality however. Most notably, GRacket is a GUI application under Windows (as opposed to a console application, which is launched slightly differently by the OS), GRacket is a bundle under Mac OS X (so the dock icon is the Racket logo, for example), and GRacket manages single-instance mode for Windows and X. The drawing and GUI libraries have also changed in further small ways. Bitmaps --- Drawing to a bitmap may not produce the same results as drawing to a canvas. Use the `make-screen-bitmap' function (from `racket/gui') or the `make-bitmap' method of `canvas%' to obtain a bitmap that uses the same drawing algorithms as a canvas. A color bitmap can have an alpha channel, instead of just a mask bitmap. When drawing a bitmap, alpha channels are used more consistently and automatically than mask bitmaps. More significantly, drawing into a bitmap with an alpha channel preserves the drawn alphas; for example, drawing a line in the middle of an empty bitmap produces an image with non-zero alpha only at the drawn line. Only bitmaps created with the new `make-gl-bitmap' function support OpenGL drawing. Use the new `make-bitmap', `read-bitmap', `make-monochrome-bitmap', `make-screen-bitmap', and `make-gl-bitmap' functions to create bitmaps, instead of using `make-object' with `bitmap%'. The new constructors are less overloaded and provide more modern defaults (such as alpha channels by default). Image formats can be read into a `bitmap%' from from input ports, instead of requiring a file path. A newly created bitmap has an empty content (i.e., white with zero alpha), instead of unspecified content. Canvases Drawing to a canvas always draws into a bitmap that is kept offscreen and periodically flushed onto the screen. The new `suspend-flush' and `resume-flush' methods of `canvas%' provide some control over the timing of the flushes, which in many cases avoids the need for (additional) double buffering of canvas content. OpenGL drawing in a canvas requires supplying 'gl as a style when creating the `canvas%' instance. OpenGL and normal dc% drawing no longer mix reliably in a canvas. Drawing-Context Transformations --- A `dc%' instance supports rotation (via `set-rotation'), negative scaling factors for flipping, and a general transformation matrix (via `set-initial-matrix').

On 10/28/2010 12:25 AM, Matthew Flatt wrote: The git repository now includes a gr2 branch for the new implementation of `racket/gui', which we've been informally calling GRacket2. The new `racket/gui' is intended to be mostly compatible with the current library, but there are some significant incompatibilities. Those differences are described below in a copy of the Porting from v5.0.x to vX.Y notes that are linked from the Release Notes page of the documentation. GRacket2 is a misnomer in the sense that you can use the new `racket/gui' with just `racket'. Furthermore, the drawing layer is mostly unbundled from the GUI layer into a separate `racket/draw' library, so you can manipulate images without a GUI (e.g., without an X11 connection). The documentation doesn't yet reflect the GUI--Draw split, Slideshow's pict library doesn't yet use `racket/draw', etc., but I hope to get to that next. More immediately, it's time for you to try out the gr2 branch for everyday work. I've switched to GRacket2 for SirMail, Slideshow, and DrRacket --- even during lecture. All library functionality is in place, but I'm sure that gaps and problems will show up as we put the library to work (and I know that some of the tests still fail). I expect to see many bug reports; once the bug reports slow down, I'll take that as a sign that GRacket2 can move to master branch. GRacket, Racket, Drawing, and GUIs -- Version X.Y includes two major changes to the Racket drawing and GUI API: * The drawing portion of the GUI toolbox is now available as a separate layer: `racket/draw'. This layer can be used independent of the `racket/gui/base' library, although `racket/gui' re-exports `racket/draw'. (The `racket/draw' library is built on top of the widely used Cairo drawing library and Pango text-rendering library.) * The GRacket executable is no longer strictly necessary for running GUI programs; the `racket/gui/base' library can be used from Racket. The GRacket executable still offers some additional GUI-specific functiontality however. Most notably, GRacket is a GUI application under Windows (as opposed to a console application, which is launched slightly differently by the OS), GRacket is a bundle under Mac OS X (so the dock icon is the Racket logo, for example), and GRacket manages single-instance mode for Windows and X. The drawing and GUI libraries have also changed in further small ways. Bitmaps --- Drawing to a bitmap may not produce the same results as drawing to a canvas. Use the `make-screen-bitmap' function (from `racket/gui') or the `make-bitmap' method of `canvas%' to obtain a bitmap that uses the same drawing algorithms as a canvas. A color bitmap can have an alpha channel, instead of just a mask bitmap. When drawing a bitmap, alpha channels are used more consistently and automatically than mask bitmaps. More significantly, drawing into a bitmap with an alpha channel preserves the drawn alphas; for example, drawing a line in the middle of an empty bitmap produces an image with non-zero alpha only at the drawn line. Only bitmaps created with the new `make-gl-bitmap' function support OpenGL drawing. Use the new `make-bitmap', `read-bitmap', `make-monochrome-bitmap', `make-screen-bitmap', and `make-gl-bitmap' functions to create bitmaps, instead of using `make-object' with `bitmap%'. The new constructors are less overloaded and provide more modern defaults (such as alpha channels by default). Image formats can be read into a `bitmap%' from from input ports, instead of requiring a file path. A newly created bitmap has an empty content (i.e., white with zero alpha), instead of unspecified content. Canvases Drawing to a canvas always draws into a bitmap that is kept offscreen and periodically flushed onto the screen. The new `suspend-flush' and `resume-flush' methods of `canvas%' provide some control over the timing of the flushes, which in many cases avoids the need for (additional) double buffering of canvas content. OpenGL drawing in a canvas requires

Its worth noting that if you use 'su -c make install' things work because 'su -c' changes $HOME to /root whereas sudo does not. The user used 'sudo make install' because he passed '--prefix=/usr/local' to configure and so expected things to install there. I suppose this is a case of user error but its extremely subtle so I wouldn't call it that. Maybe during installation ~/.racket shouldn't be used, and /tmp/racket could be used instead or something? _ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/dev _ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/dev _ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/dev

I think the conventional solution is for `make install' to do much less work than it current does. In normal Make-built software, `make' does all of the compilation, and `make install' just does the copying. That way, `make install' wouldn't be doing things like reading preferences and creating the '.racket' directory. Yea, I kind of feel like 'make' should build all the collects and docs and whatnot.

[racket-dev] raco setup hangs
`raco setup' hangs when it tries to build my planet package.

If I cilck on the line:column thing in the toolbar area next to the gc icon it and select 'show line and column numbers' then the line:column becomes hidden. If I then click in the same area to bring up the popup I see that 'show line and column numbers' is still selected and clicking it does not bring back the line:column display. Also if line:column is being shown and I click 'show character offsets' (which did not already have a checkmark next to it) then the line:column goes away and I see 'show line and column numbers' without a checkmark next to it (when before it did have one). A further issue seems to be if the line:column display is hidden then its not clear where to click to get it back.

[racket-dev] current-load/use-compiled

Re: [racket-dev] documentation reorganization
I think the 'guide' and 'reference' links could use a description of
what they are similar to the tutorial links.
On 07/01/2011 06:45 PM, Ryan Culpepper wrote:
I just pushed a commit intended to improve the usability of the main
documentation page, especially for newcomers to Racket. You can also
see the new version here:
http://www.cs.utah.edu/~ryan/tmp/doc/
If you have a manual in the trunk, I probably changed it
slightly. Take a look at the changes. The rest of this message is
about the rationale behind the reorganization.
--
Back in May, we heard from a newcomer to Racket who had gotten lost in
the documentation and ended up going down the wrong path. His report
sparked a discussion about, among other things, changing the
documentation to make it more accessible to newcomers and
visitors. While there are some gaps in the content of the
documentation we have available, the primary problem seemed to be the
organization; the newcomer didn't find the right manuals to read.
The new documentation has four conceptual parts: Orientation, Racket,
Teaching, and Everything Else.
Orientation: The Getting Started link now stands alone; previously it
was too easy to miss. The tutorials are now labeled as such in a
separate section.
Racket: The previous organization was too egalitarian. The Racket
Reference was bare centimeters above the R6RS manual; R6RS is the
standard, right?---guess I should start there! Core libraries were
scattered throughout the documentation; you have to scroll to find the
GUI manual.
The new Racket Language and Core Libraries section makes it clear
where the serious, comprehensive material about Racket starts. The
core libraries are part reassurance (good, there's a standard GUI
toolkit) and part advertisement (oh, there's a standard way of
producing documentation).
Teaching: The teaching materials are important enough to the Racket
mission that they come next.
Everything Else: There are a couple lesser improvements to the rest of
the manuals.
First, the old Languages section (again, overly egalitarian) is now
much smaller, and its role is clarified. Racket is The Language; these
are others... what does that mean? The link explains it.
Second, I've done away with the @bold{X}: Y manual naming
convention. In some cases this convention works, but in most cases it
was a poor fit. @bold{Guide}: Racket is a bit inscrutable compared
to The Racket Guide, and @bold{Version}: Racket Version Checking
is grandiose for a manual that documents eight exports. The convention
was confining, and it led to an arms race of bolding. If your manual
didn't start with a bold keyword, it looked pitiful. I've changed
major manuals to have names such as The Racket Guide, The Racket
Drawing Toolkit, etc. I've renamed a few other manuals in that style,
such as Web Applications in Racket (used to be Web: ...) and
Extending DrRacket (used to be Plugins: ...). Use the unbolded
X: Y pattern for manuals that are just the documentation for some
collection; otherwise consider giving the manual a more descriptive
name.
--
This is intended as a first step. In particular, I wanted to get the
first three parts (Orientation, Racket, Teaching) in better shape in
time for the upcoming release.

[racket-dev] current-read-interaction
For Honu I set up the `current-read-interaction' procedure to read a string of characters ended by a newline and to parse that with `honu-read-syntax'. This leads to two issues 1. this works on the command line but in drracket after typing '1' and pressing enter the prompt never comes back and drracket chews up some cpu. 2. I wanted to make ctrl-d quit the repl immediately so I look for an eof-object in the stream and if found I try to return #'(exit). The Honu parser gets involved at that point so it doesn't quite work, but anyway is that the right strategy? Here is my repl reader: (define (read-one-line name input) (define quit? #f) (define one-line (with-output-to-string (lambda () (let loop () (define next (read-char input)) (when (eof-object? next) (set! quit? #t)) (when (not (or (eof-object? next) (char=? next #\newline))) (display next) (loop)) (if quit? ;; this isn't right, somehow communicate to the system that the repl should close #'(exit) (honu-read-syntax name (open-input-string one-line (provide configure) (define (configure . args) (current-read-interaction read-one-line)) _ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/dev

Re: [racket-dev] no backtrace for error in macro
So is there a more efficient way to debug the issue than looking at the macro debugger that you know of? Also FWIW the error I meant arose from exactly the situation below. I created a new identifier meant to be used as a literal: (define-syntax my-new-literal (lambda (stx) (raise-syntax-error 'literal this is a literal meant to be used inside a macro)) And the literal ended up in code outside the intended form that would have consumed it so the literal's syntax error was raised.

Re: [racket-dev] Identifier macros
Actually I would hope that section 1.2 (syntax model) in the reference would explain exactly how macros are invoked. Unless I'm missing something it never mentions exactly what syntax object is passed to the transformer function once a macro binding is observed. It could either go in paragraph about transformer bindings in the 'expansion steps' section (1.2.3.2) or in the section specifically about transformer bindings (1.2.3.5). Something like If the binding appears at the head of a syntax object then the entire syntax object is passed as the argument to the transformer. In any other context only the syntax object for the binding itself is used as the argument.

If I just look up identifier macro, trying to figure out how to write one, I get a link to section 16.1.5. Ah, that makes sense. Thanks! This does not directly state the context involving syntax-rules; it instead describes an identifier macro simply as ...works in any expression. The documentation then goes on to present syntax-id-rules as a mechanism for identifier macros, presenting set! transformation as well. So while it doesn't explicitly state that set! transformers and identifier macros are the same thing, it does appear to imply it and doesn't clarify the matter. If we're going to use identifier macro as an indexed technical term, we should probably have a more precise discussion of it in the reference manual as well that spells out how these things work. I know I wasn't the only one surprised to find out that ordinary define-syntax syntax-case / syntax-parse macros can expand (what most people would call) identifier macros. The only way I can figure this out in the documentation is from a very close reading of the low-level expansion model, which is not written terribly plainly to begin with. --Carl Carl Eastlund On Wed, Dec 5, 2012 at 2:12 PM, Matthew Flatt mfl...@cs.utah.edu wrote: At Wed, 5 Dec 2012 09:41:37 -0500, Matthias Felleisen wrote: I think two additions/refinements would be good here: 1. The section on identifier macros in the Guide (16.1.5) should mention that define-syntax introduces short-hands for identifiers, period. I think a `define-syntax' that binds to a procedure of one argument is what you mean --- but section 16.1 is about `syntax-rules' and `syntax-id-rules', not procedures as transformers. Improving the start of 16.2 along these lines makes sense, along with a better connection to 16.1. Or maybe you're suggesting a different organization than the current 16.1--16.2 split? I'm still unclear on the specific text that confused Carl, though. Was it 16.1? _ Racket Developers list: http://lists.racket-lang.org/dev _ Racket Developers list: http://lists.racket-lang.org/dev

[racket-dev] build: schemef.h - schemex.h
The ubuntu ppa build has been failing for a while, and I finally tracked it down to this issue: src/racket/src/schemef.h has a newer timestamp than src/racket/src/schemex.h on a fresh git checkout from github. This results in the make system trying to execute the following make[6]: Entering directory `/home/jon/tmp/plt2/src/b/racket/src' racket ../../../racket/src/makex.rkt ../../../racket/src/schemef.h ../../../racket/src/schemex.h On a fresh machine with no racket installed, this fails because there is no 'racket' executable available. I'm not sure what the best solution is. Right now I'm thinking of just doing a 'touch *' immediately after a 'git pull' for the build machine, since schemex.h probably should not be built every time.. But in general I imagine someone might run into this issue on their own machine. I'm mildly surprised it hasn't happened to anyone yet. For whatever reason, this issue only started appearing about 3 weeks ago. Perusing the git log doesn't show much related to schemex.h or whatever so I'm not sure what the root cause is. _ Racket Developers list: http://lists.racket-lang.org/dev
