Text to HTML Table Converter 1.2

Now has unbuffered reads and better flag support

Unbuffered Input Reading

I added an pseudo-unbuff_read() function to the program (pseudo because it is really a sentinel-terminated loop concatenating a buffered read to a string)

def unbuff_read(END):
""" Reads one char at a time from stdin until reaches a "stop" character """
str = ""

while 1: # no do-whiles or assignments-in-conditionals in python :`(
# Compare the end of the string (same length as END) to END
if str[ len(END) * -1 :] == END:
str +=

return str

The parameter that you pass into this function called END breaks out of the read loop and returns the str read in up to that point. The default END is '\n.\n' which is a newline followed by a period and then another newline. This syntax is the same as the one used to stop reading the message body(DATA) when talking to smtp mail servers.

To quit the program just type in the END variable by itself.

Better flag support

Function argsContain():

def argsContain(flag):
""" Flag is the letter/word/etc that follows the '-' or '--' in the options """
# search for flag in options part of args i.e. before filename
for arg in sys.argv[1:len(sys.argv)-1]:
if arg.find(flag) != -1:
return True
return False

This function goes through each argument before the filename and searches for a specific flag like "f" or "v". The two instances that used to search for flags have been replaced with a call to this method enabling syntax like
$ python -vf input.txt


$ python -fv input.txt

I kept my debugging code which consists of a function called debug() and a commented call to it after main() to make it easier to play around with the code by just uncommenting the call(and maybe commenting main()) and putting code in the debug() function.
