[racket-users] Small feature request: keyboard shortcut in HelpDesk to go to search

[Laurent]

In case it's simple enough, would it be possible to have a keyboard
shortcut in the HelpDesk to go to the search bar, on any help page?

(Btw, I can't even reach the search bar by repeatedly pressing Tab on
Chrome at least.)

Thanks!
Laurent

Re: [racket-users] DrRacket stubbornly indents code as if it were Racket

[Gustavo Massaccesi]

You can select the "text mode" in the menu

  Edit>Modes(near the bottom)>Text mode

It disables indentation, but it may disable too many features.

For example it disables also parens matching :( .

And it also disables background syntax expansion, but you can still
use the "check syntax" button manually.

(Perhaps you can create a "no-indent" mode, I didn't look at the code.)

RE: [racket-users] DrRacket stubbornly indents code as if it were Racket

[Yuhao Dong]

I'm clearly referring to the mechanism in which a #lang can tell DrRacket to 
use a different indenting mode in "Racket mode", not anything to do with text 
mode.

Re: [racket-users] DrRacket stubbornly indents code as if it were Racket

[Matthias Felleisen]

You will need to find where drracket parses the first line and then install the 
mode that you want. I do not know whether a language per se can access this 
line. But we are moving toward #lang precisely for that purpose. I am sure 
Robby will welcome proposal on how to change this and even patches (he's 
currently in a different time zone). -- Matthias

Re: [racket-users] tex2page and Racket(latest version) problem

[Vincent St-Amour]

Hi,

How did you install Racket? It looks like you have used the wrong
installer. You probably want the Mac OS 64 bit version.

[racket-users] time_t and size_t ffi types

[Eric Dobson]

I'm currently on working on bindings to a foreign library that has elements
in structs that are defined as time_t and size_t. I couldn't find anything
in the core ffi types that corresponded to these, so currently I am using
int64_t as that was what I found was correct for the system I'm currently
working on (OS X), which might not work when I try to port this to other
OS's (Linux).

What is the best practice for using such types, is there any core c-type I
should use or should I just roll my own?

What about _size in ffi/unsafe ?

[racket-users] no plot zooming on local build--update procedure wrong?

['John Clements' via users-redirect]

I notice that currently, plot snips are not zoomable in my local build. The 
release candidate doesn’t seem to have this problem. I believe I’ve had this 
problem since before the release candidate was built. This suggests to me that 
the problem is not that there’s a bug in the code, but rather that my 
installation is messed up somehow. 

I’m up to date on the git.racket-lang.org repo, and I just ran ‘make’, and I’m 
still seeing the problem.

I’m guessing that I could fix this by discarding my tree and building again 
from scratch, but if my update procedure is wrong (git fetch then ‘make’), I’ll 
keep having this problem again and again.

Any ideas?

Many thanks,

John

Re: [racket-users] no plot zooming on local build--update procedure wrong?

[Matthew Butterick]

I've had the same issue with plot zooming not working from my git build. I 
don't have a theory but it at least suggests the problem may not be strictly 
localized.
