- First, a bugfix, without which indent-1.6 can't reliably read from standard
- input:

- {
- size += (2 * BUFSIZ);
- stdinptr.data = xrealloc (stdinptr.data, size);
- + p = stdinptr.data + stdinptr.size;
- }
- }
- while (ch != EOF);

- Second, a question, as a new user of indent:
-
- I get the impression that indent doesn't care at all about the _incoming_
- whitespace, i.e. that it doesn't learn anything about the program by looking
- at the nature of whitespace. Is this a correct impression? (I'm thinking
- in terms of the "design" of indent; based on the docs, which I admit I haven't
- read in great detail, it looks like it changes whitespace, but doesn't
- try and interpret incoming whitespace per se.)
-
- The reason I ask is that I have a situation where a command like
-
- bash$ indent < foo.c | indent -T bool -T ffelexToken | indent > bar.c
-
- produces a file named bar.c that is different in subtle ways from the
- file named baz.c produced by
-
- bash$ indent < foo.c > baz.c
-
- (where foo.c remains the same in both cases).
-
- Is what I'm observing possible, given the design of indent, or am I seeing
- a manifestation of, perhaps, a bug like an uninitialized variable?
-
- The actual differences are limited to cases of the form:
-
- union
- {
- struct
- {
- blah blah blah;
- } xyzzy;
- ...
- } ...
-
- In one file, the xyzzy; is as shown; in the other, it is on a subsequent
- line indented so it lines up with the "struct":
-
- struct
- {
- blah blah blah;
- }
- xyzzy;
- ...
-
- I was trying to determine whether, indenting with no options (i.e. -gnu),
- there was any need for me to supply typedef names. It _seems_ the answer
- should be "no", but getting these differences worries me.
-
- Let me know if I'm just missing the boat here, or if I've hit on something
- and should send in some sample code (or if you want me to try and debug
- this thang)!
