In particular, `raco pkg show' should work when the user does not
have write access to the installation directory or installation-wide
package database.
Merge to v5.3.2
Had been specifying Scheme lexer for code blocks, while waiting for
new Racket lexer to wend its way from Pygments to Pygments.rb to
Linguist to GitHub.
That day is almost here: Linguist will soon update and deploy to
GitHub. And Racket 5.3.2 is about to release. As a result, I think
this is the correct time to switch to the Racket lexer: It should be
live on GitHub by the time people are using Racket 5.3.2.
/cc @rmculpepper -- I think this commit should go into the 5.3.2
release.
- parsing of polydots values was fixed
- certain polydots error cases are now reported
- the custom application rule for values was fixed
Closes PR 13365
Please merge to 5.3.2
The problems were with
* `sqrt' and `expt' on single-flonum complex numbers
* `asin' and `acos' on single-flonum arguments and complex results
* `atan' on mixtures of single-flonum and exact arguments
* `gcd' on mixtures of single-flonum and flonum arguments
The synchronization result of a log receiver is now a vector of four
values, instead of three, where the last one reports the name.
Also, an optional argument to `make-logger' provides a notification
callback for each event sent to the logger.
These changes enable more control over loggers and events. Suppose
that you have processes A and B, and you want all log events of A
to be visible to B, but not vice-versa. Furthermore, you want the
log events to appear at B in the right order: if A logs an event
before B, then A's event should arrive at a log receiver's before
B's. Now that a log receiver gets the name associated with the
original event, and now that the name can be re-sent in a
`log-receiver', it's possible to give A and B separate loggers and
send all of the events from A's logger to B's logger. Furthermore,
you can use the notification callback so that when an event is logged
in B, you can make sure that all available events from from A's
logger have been transferred to B's logger.
it only looks left and right at hyphens and only
up and down at pipes, etc. This better handles the
case where you have something like this:
+--------------+
| (<= a-x b-y) |
+--------------+
Before this commit, it would have adjusted the hypens
inside the identifiers
Before this commit, things like this:
(define c% (class object% (super-new)))
(object-name c%)
would produce
'class:c%
but now classes and interfaces will be more like procedures and, in
the example above, just produce:
'c%
The underlying goal is to make error messages generated from contracts
like
(is-a?/c frame%)
have "(is-a?/c frame%)" in the message, instead of "(is-a?/c
class:frame%)"
