I sent the copy. I use usul regularly so I still have the whole repo
locally.

In what way is the elastic tabbing different from what Plan9's mc(1)?

Works!

Try putting the library at the end. Some linkers display rather...
classic behavior when linking statically (i.e. only linking in the files
that are needed, but if you name a library as first thing, then no file
is needed at that point).

Attachment above. :)

cc -lutf -L. -o cat cat.o util.o gives:

cat.o: In function `main':
cat.c:(.text+0x179): undefined reference to `chartorune'
cat.c:(.text+0x1dd): undefined reference to `runetochar'
cc: error: linker command failed with exit code 1 (use -v to see invocation)

I have libutf.a in the current directory.

I can't event compile this:
#include 

int
main(int argc, char *argv[])
{
Rune r;
chartorune(, "");
return 0;
}

with
cc -L. -lutf -o utf utf.c
getting
/tmp/utf-1e880d.o: In function `main':
utf.c:(.text+0x33): undefined reference to `chartorune'
cc: error: linker command failed with exit code 1 (use -v to see invocation)

This sounds interesting.

This is a surprise. Where did you get usul from? I'm not sure even I

I have been wondering lately about resurrecting usul, since 'tabular
munging' with Unix utilities without the ability to set $FS and $RS
can be really unpleasant, and I've had to do quite a bit of it
recently.

I did also write a program to complement usul which performs elastic
tabbing on its input, the idea being that you end up with a nice
tabular view in your terminal. I think ideally you might want 'real'
terminal support for it though, as when printing to the tty you either
need to buffer a lot of data (i.e. until a line with no FS), or you
need to do crazy tty-rewriting ANSI escapes, which it did support but
is a massive hack.

layout the data in a tabular way

But would it still be plain text?

I'm having problems compiling usul:
cc -lutf -o cat cat.o util.o
cat.o: In function `main':
cat.c:(.text+0x179): undefined reference to `chartorune'
cat.c:(.text+0x1dd): undefined reference to `runetochar'
cc: error: linker command failed with exit code 1 (use -v to see invocation)
gmake: *** [Makefile:15: cat] Error 1

I mention have libutf.a in my path.

Re: [dev] ASCII Delimited Text

[Truls Becken]

As an anecdote, I actually wanted to use US/RS delimited text at work
a while ago to consume XML downloaded from some service. The idea was
to use XSLT to convert the data to a sane format that I could easily
ingest. As it turns out, that was a no-can-do because XSL transforms
are defined in an XML dialect, and XML is not allowed to contain ASCII
control characters, not even on escaped form  So you cannot
express this transformation to any of the XSLT engines I tested! I
ended up using a pair of Unicode control chars instead.
