Hello,
Below is a diff to modify 'wc' in order to fix wc's concept of a "word" to match
the definition of "word" used by egrep(1), regex(7), regcomp(3), perl, and other
tools. Specifically, the definitition of a "word" is a sequence of alphanumeric or
underscore characters.
The wc tool, however, considers anything other than \n, \r, \t, \l, \v, and <space>
to be valid word-characters. For example, the text,
"The-rain+in(Spain)falls*mainly{on}the......plain", is only one word, according to
`wc'. The tools mentioned above will report nine words.
Good news! The fix is rediculously simple -- only a few lines! Here is the output
of cvs diff on the file, "textutils-XXX/src/wc.c" :
diff -r1.1.1.1 -r1.2
223c223,224
< switch (*p++)
---
> int c = *p++;
> switch (c)
250c251,254
< in_word = 1;
---
> if( isalnum((c)) || c == '_' )
> in_word = 1;
> else
> goto word_separator;
