[9fans] OT: Acid question?

[ISHWAR RATTAN]

I am trying to learn how to use acid for source
level debugging using the built-in functions. I waould like
to know how to display/exmine the varibales used in the
program. Sample code for context:
  void main()
  {
    int a, b, c;
    a = 12;
    b = 21;
    c = a + b;
    print("c: %d\n", c);
    exits(nil);
  }

  program is compiled and acid is called on the image:
  acid: new()
  ..
  acid: bpset(print)
  ..
  acid: next()
  ..
  at this point a = 12 has been executed. How to examine
  the value in acid?

Acid Tutorial by Tad Hunt also may be useful. I see it in
/doc/acidtut.pdf in Inferno release but I couldnt find a web link.

I had looked through /sys/doc/acid.* and was unable to find
the information there. Maybe it is something trivial :-(

acid: *(main:a\D)

produces:
<stdin:23:(error) colon: local variable not found

[Axel Belinfante]

you may want to try using the -N flag of 8c
(I guess you did not, and thus your variables were optimized away)

of course I may be completely wrong - trying to learn something here too...

Re: [9fans] OT: Acid question?

[Gabriel Diaz]

Hello

I think Axel is right.

without -N i can found a in AX b in CX, etc.

with -N you can do what geoff suggested:
*(main:a)\d

the paper http://plan9.bell-labs.com/sys/doc/acidpaper.html says:

"Acid provides library functions to step through source level
statements and functions. Furthermore, addresses in Acid expressions
can be specified by source file and line."


is that sentence talking about the 'main:a' string? or is just like
'file.c:line' ? (i can't found the correct syntax if the second one is
accepted).

slds.

Thanks -N flag did the trick.

oh, i meant /doc in Inferno's root directory. If you have inferno
installed, you can check it up. Else, you need to install inferno
somewhere to see the file, I think.

Why is a question about acid off-topic?

Because application questions on (l)unix mailing-lists would be off topic
because the application is made by some other people somewhere else, I
would guess.
