Your initial e-mail suggested having language levels associated with files.  I believe that the principal difficulty in implementing this is the fact that there's not an obvious cross-platform file metadata format.  Also, some users might be surprised when they open a new file and it behaves in a "weird" way. Finally, I think it's not an incredibly high-priority item; I just counted, and I count six keystrokes in going from (module...) to pretty big, and four keystrokes to go back again. Of course, this doesn't include the irritation of forgetting to switch, and running the program only to be told that you have more than one expression (or worse, simply evaluating the module without opening it).</blockquote><div> Since I my average drscheme window opens with about 10 tabs (I have no idea if everyone else is doing this or not), and 8 or 9 of the tabs would be "pretty big", that makes the operation 8*6 = 48 keystrokes every other time i load drscheme.  either that or load drscheme, set "pretty big", close drscheme, and reload drscheme, then do the 2*4 = 8 keystrokes to fix the 2 module tabs."  However the time to launch drscheme is quite large, expecially for those of us running "plt-full".  ( i.e. all the collects from the svn, not just the bare minimum from the standard distribution).  Also, I tend to run 3 instances of drscheme at a time (i wrote a script to open multiple tabs with multiple windows), which increases shutdown and restart times. A thought....  The thing that prevents me from writing a fix for this myself is that i cannot effect things from the interactions window.  I.E.  if from the interactions window i could type '(set-language (tab 4) "(module ...)")', i would probably find my own solution to this, and integrate it into my "project manager".  (my "project manager" runs other instances of drscheme from the command shell via "system" when you want to edit a file.).  I.E. I can't do it from the interactions area manually, so I won't be able to figure out how to write a program to do it without launching a major "research project". Now i'm actually going somewhere with this...  Is it possible to load drscheme, and then from the drscheme interactions window, load drscheme?  Then from the interactions window of drscheme instance #1 be able to manipulate in some way drscheme instance #2, with something like '(set-language (tab 4) "(module ...)")' perhaps?  (i'm sure I have the syntax wrong, but you get the idea) </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">This is probably more of an issue for you than for most, because most of your code is in the "pretty big" language; I suspect that for many PLT users, nearly all of their code is in modules. I think that Danny was suggesting that you throw _all_ of your code in modules, wrapping the "pretty big" ones with (module <module-name> (lib "pretty-big.ss" "lang") ...) (that's from memory, apologies for any errors there).  Of course, there may be some reason why this isn't possible for you.</blockquote><div> Yes, unfortunately most of my libraries, call libraries, that calls a library that needs to call eval.  however, if i use modules, the namespace of the intermediate library dissapears, and the call to eval will not work, because it happens at the top level namespace.  Since it needs access to the namespace of the library that called it, and not the top level namespace, I must put all my libraries in the top level namespace.  Of course I can still use closure based modules, but that dosn't let me use the neat module tools that i'm hoping to discover as i start using modules more often. :)  {note, it's been over a year since I tried, so i may be off in some of the details}  </div> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Hope this helps ... to clarify the problem, at least.
