For the amusement of all concerned I attach indent5.c which is lying
around here at the moment. I'm actually busy and don't have a lot of
time to fart with it. This is a debugging and elaboration of David Fix's
indent program offered here earlier by a self confessed C illiterate.
This is more or less doing the business. I get in files on a long line
(up to 2595 characters long) preprocess and indent5 them. I don't
understand all of the code, but the mouse still works :-). I'm caught
with this line
char c;
if (c == ',' || c == ':' || c == ':')
as it always passes as true. Then it folds the line in some specious way
and I lose three letters. I did try going to the hex code
if (c == '0x3b' || c == '0x3a' || c == '0x2c')
and gcc got really annoyed with me - it always passes as false, it
appears wrong syntax?
indent6.c:79: warning: comparison is always false due to limited range
of data type
indent6.c:79:39: warning: multi-character character constant
indent6.c:79: warning: comparison is always false due to limited range
of data type
indent6.c:79:54: warning: multi-character character constant
indent6.c:79: warning: comparison is always false due to limited range
of data type
That aside, I'm basically running.
Input line Up to 2595 chars (2171 with control chars stripped)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~etc.
Output line (115 , then 65-115)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ (115 of them)
~~~~~~~~~~~~~~~~~etc
~~~~~~~~~~~~~~~~~
This C is handy stuff, worth the effort imho. Can anyone throw me a bone
on the line above? I'm trying to find ';' ':' or ',' to fold the line
there. But the test is bad. BTW, for beginners, I would reccomend gnu
indent, which passes over code and lines it up.
