[racket-users] Hi Racket Users Fellows: Is there a way to render LaTeX with --htmls
Hi Friends:
With minlatex.rkt functions I can successfuly render HTML with LaTeX in
one-page documents (directly from DrRacket or with Scribble --html). But for
multi-page options, for example with Scribble --htmls, the render is something
like:
\[e^{i \pi}+1=0\]
Question: Is there a way to render multi-page HTML with LaTeX code?
Thank you in advance for any hint concerning this problem.
Sincerely, Enrique Comer

Re: [racket-users] begin-for-syntax causes syntax objects to expand to a different #'quote
Yeah, I would guess that too. Anyway, it doesn't seem to do all phases. So I just shift the phase down every time I see a begin-for-syntax.

Re: [racket-users] How to make rackunit show tests succeeded?
The Overeasy package uses the Racket logger. Add "info@overeasy" to your logging selector, such as in the DrRacket Log window, or in environment variables or on the command line: http://docs.racket-lang.org/reference/logging.html Neil V. -- You received this message because you are subscribed to the Google Groups "Racket Users" group.

There's a #:phase option available when specifying literals: http://docs.racket-lang.org/syntax/Parsing_Syntax.html?q=syntax-parse#%28form._%28%28lib._syntax%2Fparse..rkt%29._syntax-parse%29%29 On Wed, Dec 16, 2015 at 9:55 PM, Leif Andersen wrote: > Okay, that makes sense, thanks. > > So out of curiosity, when doing a `syntax-parse`, is there any way I > can pass in phase level 1 quote as a literal? > > ~Leif Andersen > > > On Wed, Dec 16, 2015 at 6:44 PM, Sam Tobin-Hochstadt > wrote: >> That depends on what you're trying to do, but probably not.

Hi Neil, I pasted the above (everything down to "'(0 1 2 -1 -2)") into "foo.rkt" and then ran "racket foo.rkt" There was no output. I went to the docs page for it and create bar.rkt using the first example test from your docs: #lang racket (require (planet neil/overeasy:3:1)) (test (+ 1 2 3) 6) Again, "racket bar.rkt" Again, no output.

[racket-users] How to make rackunit show tests succeeded?
Hi folks, I'm just getting started with rackunit, and I was very surprised when I found that it simply emits nothing if a test succeeds. Every other testing framework I've used before will print "ok" (or etc) on a successful test, so that you can differentiate between "the test succeeded" and "the test wasn't run." check-equal? returns so I can't just wrap it in another function that prints "ok" on success.

Re: [racket-users] begin-for-syntax causes syntax objects to expand to a different #'quote
That depends on what you're trying to do, but probably not. Going under a `quote-syntax` doesn't change things, it's just that those identifiers are usually used in a macro somewhere else. But it would depend on your application. Note the handling of submodules, though, in particular the call to `syntax-shift-phase-level`.

Re: [racket-users] begin-for-syntax causes syntax objects to expand to a different #'quote
The identifiers are the same, but only when comparing their phase-1 bindings. When doing traversal of syntax objects, you need to keep track of the phase that identifiers are meaningful at. Here's a version of your paste comparing at the right phase: http://pasterack.org/pastes/95574 Here's some quite complex code that walks fully-expanded syntax, and (I think) handles phases right as of yesterday: https://github.com/samth/pycket/blob/master/pycket/pycket-lang/expand.rkt . See the `current-phase` parameter.

[racket-users] begin-for-syntax causes syntax objects to expand to a different #'quote
Hello, I am finding that when I have a syntax object: #'(begin-for-syntax (define-values (x) 5), when I expand it it becomes: #'(begin-for-syntax (define-values (x) '5). However, the quote in that expansion will not be free-identifier=? to the one if I were to type it out by hand: #'(begin-for-syntax (define-values (x) '5), and expand that. If however, I have a `begin` rather than a `begin-for-syntax`, giving me: #'(begin (define-values (x) 5) it works as expected. (The quote it expands into is free-identifier=? to the one that I am using.) I am calling expand (or expand-syntax) directly, and not really using any phase levels outside of whatever `expand` may use. Here is my code: http://pasterack.org/pastes/78711 #lang racket (define x (expand #'(begin-for-syntax (define-values (x) '5 (define y (expand #'(begin-for-syntax (define-values (x) 5 (define (ident=? stx) (syntax-case stx () [(_ (_ (_) (var _))) (free-identifier=? #'var #'quote)])) (syntax->datum x) (syntax->datum y) (ident=? x) (ident=? y) Is this expected behavior? If so, can you give me some intuition as to why? Thank you. ~Leif Andersen -- You received this message because you are subscribed to the Google Groups "Racket Users" group.

Re: [racket-users] how to render scribble/lp2 with current manual style
I think the missing `f` in the left-hand margin reflects a missing
`defmodule`. Adding
@defmodule[some-module]
or
@declare-exporting[some-module]
makes `f` appear as expected.

Perhaps, since it also implicates semantic issues, not just formatting. For
instance, the following code produces a "<*>" link in the left-hand margin, but
not an "f" link (as would be typical for `scribble/manual`).
#lang scribble/lp2
@(require scribble/manual)
@title[#:style manual-doc-style]{Greatest function ever}
@defproc[
(f
[x number?])

Squares a number.
@chunk[<*>

Re: [racket-users] how to render scribble/lp2 with current manual style
One solution is to attach `manual-doc-style` to a title:
#lang scribble/lp2
@(require scribble/manual)
@title[#:style manual-doc-style]{Example}
@chunk[
(define (f x) (+ x 1))]
If you don't want to show a title, then it gets trickier.
Maybe there should be a `scribble/lp-manual` to provide the manual
style in the same way as `scribble/manual`.

If you make these two Scribble files and click "Scribble HTML" in DrRacket, the second one (with `#lang scribble/manual) will render in the current manual style.
