I have tried to collect all the programs posted.  I haven't
looked at any of them in real detail (at least not yet).  I did
try compiling and running all the ones I got, but it isn't always
easy to see how well they are working because of different
treatment of some things.  I would like to make this request, to
make comparing the programs easier, namely, when a /*...*/
comment is removed, put a single space character in its place.
That will make it easier for me to zero in on just where there
are real differences in behavior, which would help me post a set
of example cases for people to try.

To help people out, here is a test input file that I found on the
CLC wiki site (with thanks to Lew Pitcher for steering me to
this).  It certainly isn't a complete set of tests, and it has a
glitch of sorts because it assumes //... style comments are not
to be treated as comments, but I think it still can be helpful
to try out different uncommenting programs.

   This solution does not deal with other special cases, such as

   since these aren't mentioned up 'til then in K&R2.  Perhaps this is
   cheating.

   Note that this program contains both comments and quoted strings of

> Short problem statement:  a C program to remove comments from C

The details of the specification seemed a little off to me but I didn't
feel anyone had really mailed it yet, so I had a go myself.

I don't think I've really nailed it either.  The requirement to preserve
uncommented line continuations breaks the natural layering of the input
process.  I've done done that with a hack: line continuations are echoed
as they are read unless this is suppressed by passing a null output file
pointer to get_logical.  This passes "state" information ("are we in a
comment?") down into the lowest level input function which I'm not keen
about.  However, I think it works.

Nothing else is really interesting about it.  Characters from logical
lines are read, and a function is called to handle each of the different
cases.

I view of Bart's comments about functions for the sake of them, I
suppose it's worth mentioning that once I'd found myself writing a test

  if ((c = get_logical(in, out)) != X && x != EOF ...

a couple of times, I decided to write a one-line function so I could
write

  if (next_not_eof_or(X, &c, in, out) ...

instead.  I think it just about pays its way.

Nope.  That version did not preserve continuations that follow a /
which, in the end, is not the start of a comment.  They need to be
counted (in this program organisation).  Annoyingly, I started by just
counting them but that complicated the code the called get_logical.  So
then thought I could make things simpler by just conditionally echoing
them instead, whereas what I needed to do is to always either echo them
/or/ counts them.  With this organisation there is only one place where
they have to be put back.

Indeed not.  Thanks (I suppose!).  I'm not actively working on it though
so it's going to remain a bug.

Yes, thanks.  The \ is not echoed.  Shorter now, since I decided to get
rid of the 'next_not_eof_or' function rather then complicate it
(sometimes the program needs to echo \ sometimes it should count them).

When I ran the code on this case, it output

    alpha beta

whereas I was expecting

    alpha 
    beta

(Disclaimer: what the output was is being given from memory.)

I found several problems in this function.  Do you want to know
more about what those are, or is this enough for you to try
tracking them down without any other hints?

Hello everyone,

It's nice to see so many people joining in and putting up their
programs.  I am trying to work through the backlog of recent
traffic, which looks like it will take at least another day.
Would this weekend be a good time for me to post my code?
Sooner?  Later?  Did the sample test input file help anyone
with their own program?

I am in no hurry at, myself having precious little free
time.

The test sample that seems to consist if an uncommenting
program, or did I miss it?  Test cases from various authors
in this thread have helped me.

You didn't miss it, the test input file is indeed source
code for a comment removing program.  It was taken from
this page

    https://clc-wiki.net/wiki/K%26R2_solutions:Chapter_1:Exercise_23

and you may want to try looking there for other ideas.

My purpose is to finish my program without looking at
anybody's code.  And I will come up with some great test
cases in the process!

Oh, I wasn't suggesting anyone look at the program to see how
it works, only to use it for a test input.

If I work up a list of "interesting inputs" would you like to
see those?  I'm considering doing that but haven't absolutely
decided yet.

Yes. It would be a good supplement to the collectioon of

Some cases follow.  At the start of each example line is a marker
(==) to indicate it is an example (and which go on for one or
more lines after the ==).  End of file is indicated by <EOF>.  A
line marked with ==x is an error example.  A line marked as ==~
shows an example that might be accepted as good but doesn't have
to be.  None of the example lines have trailing spaces.

Disclaimer:  I have tried to be accurate.  Forgive me if there are
any mistakes in the labelling.  I haven't been as thorough as I
would have liked, but for better or worse here are some cases.


 ==   ''

 ==   'z'

 ==x   '

 ==x   '<EOF>

 ==    '\a'

 ==    '\
'
