1. Bug in Edita Options/Reformat ex.err

Just spotted a bug in the ex.err pre-processing of Edita that I'm too busy/lazy to fix right now, so wondered if anyone (with the sources of Edita already to hand) fancied a little challenge...

The offending program (eaerr.e) is 384 lines long. It mentions eaerr.exw but I lost that a long time ago, though if you take a copy of eaerr.e, define constant charsWide=79 (say) and delete 9 lines at the end (linelengths..end for) it compiles cleanly. Not that I claim it is well written or properly commented.

Note that I haven't managed to create an offending ex.err from OpenEu, but here is one:

C:\Program Files\Phix\p1.exw:5 
attempt to divide by 0 
 
Global & Local Variables 
 
 C:\Program Files\Phix\p1.exw: 
    o = {{0,0,0}, {97'a',98'b',99'c'}, {100'd',101'e',102'f'}} 
    x = "{{0,0,0}, {97'a',98'b',99'c'}, {100'd',101'e',102'f'}}" 

Which, with Options\Reformat ex.err checked, Edita shows as:

C:\Program Files\Phix\p1.exw:5 
attempt to divide by 0 
 
Global & Local Variables 
 
 C:\Program Files\Phix\p1.exw: 
    o = {{0,0,0}, "abc", {1"def"} 
    x = "{{0,0,0}, "abc", {1"def"}" 

Obviously it got "o" wrong, and it mangled "x" when it should be leaving strings as-is.

If no-one's interested I'll get round to it next month, or the month after that...

Interesting idea, I'd certainly be fine with that.

You could even make the "spec" part of the contest! As in what things it should change and what it should leave alone, who has considered all the cases that need to be considered, and so on. Looking back at what I wrote in 2007, it does not really meet my ideals of clear readable code, which would probably be my main criteria.

Oh, bit of a panic there, then I found this (from last Tuesday, snipped a fair bit) sitting in my inbox:

Dear valued customer. 
 
 phix.isgreat.org has been changed to phix.is-great.org. 
 
 This email is to notify you of a change to your sub domain name URL ... 
 an issue with search engines and internet quality control ... 
 abuse and problems with banned users ... 
 has required us to unfortunately discontinue the isgreat.org domain name  ... 
 very sorry ... 
 no fault of your website ... 
 We have therefore issued a new domain name ... 
 
 phix.isgreat.org 
 
 Domain has been upgraded and changed to a brand new domain name which is : 
 
 phix.is-great.org 

edita is now, of course, hosted at http://edita.is-great.org

It should run fine on all three.

Regards,
Pete

Yes. It might not actually be possible to reproduce this on OpenEu, or it may occur with a few more nesting levels, longer subsequences, or suchlike. My gut feeling is that the extra "\n" are saving it just before it goes wrong. That code hasn't clobbered an error file (to my knowledge) in the past five years, which arguably makes it pretty rare.

The "eins035.zip" and "Windows Installer" are hosted directly on edita.is-great.org; they may be a bit slow and/or unreliable and may need a few tries (it is a free host), as you probably found out the "here" and "here" are on 4shared, which I didn't think you had to register on. I will look again, as I usually do, next time I upload something.

Regards,
Pete

I should learn to read. I put a quick "test <a href=http://phix.is-great.org/phix.zip>Phix.zip</a>" on the download page which should work.
