Nothing there.  I'm getting no response from SchemeScript at all, 
anywhere.  How can I verify that the plugin is actually talking to 
Eclipse?  I've got SchemeScript menus and configurations available, 
obviously, but trying to change / start / restart any interpreter does 
nothing.

No, nothing happens at all.  No window, no prompts, no empty windows,
absolutely nothing at all.  This is on a completely different machine, usin=
g
a fresh install of Eclipse 3.1.1 and only SchemeScript 1.1.4 added to this
fresh install.  So perhaps this is not a Chicken problem after all.  Any
ideas?  Any logfiles I might look at somewhere?

[Schemeway-user] how to configure Chicken Scheme?

Hi Brandon,

 > Windows 2000 with Chicken Scheme 2.207.

First of all, you will have to make sure that you can start Chicken
from within SchemeScript. To do that, open the "Scheme/External Interpreter"
preference page and set the interpreter command-line to: 

 D:\lang\chicken\mingw\bin\csi.exe -:c

The option '-:c' is VERY important on Windows. Otherwise, you won't be
able to interact with Chicken.

Also, leave the  "Error Regexp" empty and put set to "-1" all the
"* group"s. 

Apply your changes, close the preference page, select the "Embedded
interpreter" in the Scheme menu, and start the interpreter. Does that
work?

When an error occurs, most interpreters prefix the error message with
the filename, the column number where the error occurred, etc. The
regexp can be used to detect such lines in the console and convert
these error messages to hyperlinks.

In regexp parlance, a group is simply a sub-regexp inside a set of
matching parentheses. When you match a regexp against a string, the
group numbers can be used to retrieve the substring matching the given
sub-regexp. Group numbers are determined by counting the number of
opening parentheses from the start of the regexp. For example, in the
following regexp:

   (file:)(([a-zA-Z]:)?[^:]*):([0-9]+):([0-9]+): (.*)

there are six groups, numbered from 1 to 6:

   1 = (file:), 
   2 = (([a-zA-Z]:)?[^:]*), 
   3 = ([a-zA-Z]:), 
   4 = ([0-9]+), 
   5 = ([0-9]+), 
   6 = (.*)

Well, I don't claim to be a good UI designer (in fact, it's rather the
contrary... ;-). I'm always open to suggestions/contributions/constructive feedback.

The regexp you will set in the preference page is specific to your
Scheme system (in your case, Chicken). Don't use the one for PLT. But,
AFAIK, Chicken does not include source information in its error
messages. So the regexp is useless.

Does starting the interpreter open an empty "Console window"? If so,
enter an expression in the window and press return. You should now see
the prompt and the returned value. It seems that the console window
does not detect the initial prompt. I should note that in the release
notes.


Hope this helps!

[Schemeway-user] how to configure Chicken Scheme?

[Brandon J. V. E. <bva...@gm...>]

I'm trying to get SchemeScript 1.1.4 working with Eclipse 3.1.0 on 
Windows 2000 with Chicken Scheme 2.207.

I have no idea how I might get this to work.  I have read the docs; they 
show a picture of cryptic "filename group, line number group, and error 
link group" numbers and I haven't the slightest clue what these do.  I 
honestly can't understand why anyone would design a UI that way, unless 
there's something about Eclipse development in general that's supposed 
to make this self-explanatory that I simply don't know.  I Googled 
around all over the place for answers but found nothing.  Dominique has 
even told me how to configure something in the past, but I couldn't find 
that, and maybe it was Bigloo.  I tried "2, 3, 1" for kicks but it 
didn't work.  I decided I could either ask here or directly examine the 
source code.  This seems like less work at the moment, so here it is.

Also I'm a regexp dummy.  I tried 
(file:)(([a-zA-Z]:)?[^:]*):([0-9]+):([0-9]+): (.*) just based on some 
random thing some PLT guy was using, but it didn't magically solve 
anything.  I was hoping that leaving it blank would be ok for starters, 
but since nothing's working, I do have a paranoia about whether a 
correct regexp is required.

Also, when I select "embedded Kawa" for my interpreter and then hit 
"Start Interpreter," nothing happens, so I'm wondering if my Eclipse 
setup is problematic.  Shouldn't this just do something, like bring up 
an interpreter window?  I have several older Schemeway plugins in my 
Eclipse environment.  I thought Eclipse was smart enough to resolve 
those, but could they be interfering?

Here's what does work.  I have Chicken Scheme installed in 
D:\lang\chicken\mingw\bin.  I won't quite pronounce it a "known good" 
build, as we've been developing a new CMake-based build, but it does 
seem to be working.  I have my PATH set properly and I can invoke the 
interpreter "csi" from any command prompt. 

I'd be happy for help, and I'd be happy to document what's necessary, in 
general, for people to get their stuff working.  If only someone can 
point me at the proper source of such information in the first place.

Brandon Van Every

So most of your problems seem to be related to incompatibilities
between Eclipse 3.0 and 3.1... I'll try to fix all the problems you
reported in the next couple of weeks.

I see. That's a nice feature, but I'm not sure it would be that easy
to implement and, honestly, I have other things on my todo list. But,

I changed the extensions in both org.eclipse.ui.editors and 
org.eclipse.core.filebuffers.documentSetup, the lists are in the same order, and 
the mis-behaviour is confirmed.

The latest kate does this real pretty :)   in the hiliting definitions, they 
define different colours for brackets1, brackets2, brackets3, etc... I'll send 
you a .png directly, Dominique.  Bottom-line is that you can tell at a glance

First of all, which version of SchemeScript and Eclipse are you using?

You have to change the extensions for the 'documentSetup' extension
point too (also in the plugin.xml file).

Are you using Eclipse 3.1? This problem has been reported by a
colleague of mine on 3.1. I'll look into it in the next couple of
weeks (I'll have to install 3.1 first...;-)

I don't have Kate installed. What do you mean by "tutti-frutti"?

[Schemeway-user] newbie -- glad to be on board -- a couple of issues...

[Jean R. <jea...@sy...>]

Hi/salut,

I'm glad to join this community -- I have great hopes for Eclipse.  I've been 
doing Scheme development and Linux for 2 months now and have just installed 
Eclipse today.

Some issues with schemeway:

1) syntax highlighting not consistent across scheme file extensions:
By changing the order of the extension lists (in plugin.xml), I saw the 
behaviour of the highlighting change -- it seems to behave consistently and 
properly w/ the 1st extension (*.ss in my case) and not properly for the others. 
  e.g. comments aren't green and strings are wonky in *.ssi files.

2) Speaking of strings!!  Once I close the quote, I can't modify the string.  I 
have to delete it and retype it in from scratch and hope I don't make a mistake. 
  That's not right.  Am I missing something?  If this is part of the syntax-tree 
magic of Eclipse, it's a bad idea, IMO.

3) tutti-frutti parenthesis are super for editing s-expression-based source 
files.  Kate has those -- check it out.  Could such a feature be available in 
schemeway?

Thanks for your attention.  Looking forward to playing online.
