Re: [racket-dev] Pull request for make-base-eval

I am running into this issue with make-base-eval again. Looking
through the email archive, it looks like it's come up several times
before but I couldn't figure out if there was a resolution.

For example, the code below works fine in drracket with the scribble
html button, but errors when compiled with scribble from the command
line.

#lang scribble/manual
@(require scribble/eval)
@(define the-eval (make-base-eval #:lang 'typed/racket))
@interaction[#:eval the-eval
(: my-sqr (Real -> Real))
(define (my-sqr x)
  (* x x))
(my-sqr 42)]

namespace-attach-module: a different module with the same name is
already in the destination namespace
  module name: "/home/stchang/pltpkg/racket/collects/racket/pretty.rkt"

Is the solution to just ditch make-base-eval and use make-evaluator instead?

We were waiting for a reason. This is one. I'll try it on my flight home 
tonight. (Never done any package management before.)


I suppose this is a good rule of thumb: if your docs make pictures, put 
them in a separate package.

[racket-dev] package system, minimal builds and more

[Tobias Hammer]

Hi,

i played a bit with the new package system, minimal installs and cross  
compiling. It works pretty good but i have a few problems and  
remarks/questions.
I start with a fresh yesterdays minimal source  
(min-racket-5.90.0.9-src.tgz), build it (natively for linux) and try to  
install packages.


(Given in no particular order)


* compiler-lib install fails with the following error
./bin/raco pkg install -i compiler-lib
Resolving "compiler-lib" via  
http://www.eecs.northwestern.edu/plt/snapshots/20130929-6d4ff30/catalog/

Resolving "compiler-lib" via https://pkg.racket-lang.org
Downloading checksum for compiler-lib

raco pkg install: package conflicts with existing installed
  package: compiler-lib
  module path: compiler/option

As its needed by racket-doc and similar it blocks install of a lot of  
packets



* the snapshot catalog seems to be nonexistent
If i browse to  
http://www.eecs.northwestern.edu/plt/snapshots/20130929-6d4ff30/catalog/,  
i always get a 404. Is this intended?



* redownload after fail
the package manager seems to download every packet again after a failed  
install or user interruption. Would it be worth to reuse the once  
downloaded zips if the checksum is the same (similar to the behavior of  
apt).



* raco pkg warnings
On every command i get
warning: tool "pkg" registered twice: "pkg" and  
#
warning: tool "setup" registered twice: "setup" and  
#
warning: tool "link" registered twice: "link" and  
#


/home/hamm_to/tmp/racket/_tmp/racket-5.90.0.9/ is the used installation.


* sometimes installations fail without a reason or hangs
./bin/raco pkg install -i xrepl
[...]
The following uninstalled packages are listed as dependencies of  
macro-debugger-text-lib

and they will be installed:
   parser-tools-lib
   unstable-list-lib
Resolving "parser-tools-lib" via  
http://www.eecs.northwestern.edu/plt/snapshots/20130929-6d4ff30/catalog/

Resolving "parser-tools-lib" via https://pkg.racket-lang.org
Resolving "parser-tools-lib" via https://planet-compat.racket-lang.org
raco pkg install: cannot find package on catalogs
  package: parser-tools-lib

rerunning the command and it suddenly works.


* monolithic math
currently math is one big package and installing it pulls in nearly  
everything through the docs. Is it planned to split it into -lib and -doc?



* cross compiling and installing
is it possible to install packages as part of the bootstrap process? the  
problem i have is that the build machine is a regular linux but the cross  
compile target is constrained in that it cannot install packages (no  
internet, no writable discs, ...). But i can't install via raco because  
racket is compiled for that target it does not run on linux.
I can currently work around this by installing a linux racket with same  
version, installing there and then copying share/, but thats somewhat ugly.



* More verbose require error
If i require something nonexistent i get an exception like
(require fdfsdfsdf)
; readline-input:4:8: collection not found
;   for module path: fdfsdfsdf
;   collection: "fdfsdfsdf"
;   in collection directories:
;/home/hamm_to/.racket/snapshot/collects
; 
/volume/USERSTORE/hamm_to/tmp/racket-qnx/linux-racket-5.90.0.9/collects

;/home/hamm_to/.racket/snapshot/collects
; 
/volume/USERSTORE/hamm_to/tmp/racket-qnx/linux-racket-5.90.0.9/collects

;... [22 additional linked and package directories]

Is it possible to somehow show these additional 22 entries? Maybe not in  
the error but from raco?



I know these are a lot of things and some might be obvious or result from  
misunderstanding or missing something. So thanks for enlightening answers  
to any of these.
