[stamp-devel] priorities
by Robert Strandh 30 Dec '06

Actually, I think I'll create a `priorities.text' file in the `Spec' directory instead of posting priorities here. It will be much easier to manipulate that way. -- Robert Strandh --------------------------------------------------------------------- Greenspun's Tenth Rule of Programming: any sufficiently complicated C or Fortran program contains an ad hoc informally-specified bug-ridden slow implementation of half of Common Lisp. ---------------------------------------------------------------------

[stamp-devel] Some initial thoughts
by Robert Strandh 30 Dec '06

1) I have checked in stamp.lisp and a very preliminary specification in Spec/spec.text 2) Using mel-base is going to create some problems. For one thing, mes-base seems to use base-string and base-char a lot, but that seems to be incompatible with the kind of strings used by SBCL. The solution would be to fix the declarations in mel-base. Perhaps this has already been fixed; I tripped on this problem by using an old version of mel-base. Another problem with mel-base is that it can't handle non-ascii contents of message headers and message bodies. The solution to this problem seems to be to make mel-base use flexi-streams, to scan the header in ascii mode with a default character (as flexi-streams allow) of (say) #\?, and to set the encoding of the stream for the body to whatever the content-type/charset header indicates (with a default of ascii as for the header). This would require some digging into the mel-base code, but I think it can be done. Mel-base is pretty well written. To get around this problem until mel-base is fixed, I suggest using a test folder that has only ascii characters in all of the messages. We don't want to use the `messages' function on a folder, simply because it scans the entire directory and we might have a million files in there. Instead, we must select an individual message based on the tags list, and let mel-base scan that individual message. 3) I am working on a list of priorities. I think I'll post it here and leave it open to debate. In a week or so, we should have nailed the priorities so that the students know what to work on and in which order. 4) I still intend to convert the existing Stamp code to use the ESA library, but I don't know at which speed this will happen. It would be good to have something running in a week or so. 5) We need to think about file and package structures. We should definitely create an ASDF file (named `stamp.asd'), and a `packages.lisp' file. The main package should be called `stamp', and should contain only exported symbols. Other packages used for implementation should :use the stamp package (I learned this trick from CLIM). We need to decide what other packages are required. For now, let's say we only need one: stamp-internals, perhaps with a nick name of `stampi'. We should probably have this working in a week or so as well.

[stamp-devel] what language?
by Robert Strandh 07 Dec '06

07 Dec '06

Hello, Since this list is archived and since there is likely to be people here in the future who do not understand French, I suggest we use English for this list. OK? -- Robert Strandh --------------------------------------------------------------------- Greenspun's Tenth Rule of Programming: any sufficiently complicated C or Fortran program contains an ad hoc informally-specified bug-ridden slow implementation of half of Common Lisp. ---------------------------------------------------------------------
