Turn use of a finalized ffi callout into a reported error,
instead of a crash. Clarify the existence of the finalizer
in the docs. Fix error logging of the finalizer thread.
Merge to v5.3.1
Bytecode changes in two small ways to help the validator:
* a cross-module variable reference preserves the compiler's
annotation on whether the reference is constant, fixed, or other
* lifted procedures now appear in the module body just before the
definitions that use them, instead of at the beginning of the
module body
The new argument gets to chaperone/impersonate a guard at
the prompt, and it is applied when the continuation is applied ---
based on a wrapper on th prompt tag of the continuation (as opposed to
the prompt tag of the prompt).
The new argument gets to filter results that come from a
non-composable continuation that replaces one delimited
by a prompt using the chaperoned/impersonated prompt tag.
* Stamp "plt-index.js" with the path of its generator.
* Fix most of the "use strict" and js2-mode warnings in scribble's
JavaScript.
* Some code improvements in the generating code too.
(With some edits by Eli.)
Also, add 'lsquo as allowed content.
Omitting the ` conversion in the first place was over-conservative.
There's a backward-compatibility issue with this addition (i.e., a
document might contain a backquote in a decoded context that is
meant to be rendered as a backquote), but the potential problems
seem minor.
The new keys are useful for skipping animation groups. They
actually navigate by slide name, which defaults to the slide title,
but can be specified separately with the `#:name' argument to
`slide'.
This instructs the adventurer on how to take screen shots using the
same look and feel used to take the ones that can be found at
`collects/scribblings/gui/image'.
There are also two scripts that might help automate this process.
It's very helpful to have a visual aid when dealing with a graphical
interface toolkit.
This patch adds an overview of the widgets available in the library
consisting of screen shots of the main ones and the snippets used to
produce them.
Each widget image link back to the full documentation.
The `slideshow/code-pict' library is the same as `slideshow/code', but
it works in non-GUI settings. Only the `slideshow/code' library connects
the code font size to `current-font-size', though.
The `code' macro, `define-code', etc., now support "code transformers",
which are syntax bindings that trigger otherwise-unescaped transformations
in the code to typeset (which can make the code easier to read and
friendlier to auto-indentation).
