Hi all,
in a previous post I asked help for colorizing expanded tab.
I wanted to list text files showing in colors LFs and the expanded
tabs.
I hoped to use only bash but, being impossible, I reverted to Python.
I programmed a very short script .
Here it is (... and I ask comments or critics):
# for Linux users
# starting from a list of all the lines of a text files (lFileList)
nNP=9 # n. of Not Printables characters
for line in lFileList:
nTab= line.count('\t')
if nTab > 0:
for i in range(nTab):
nPosTab=line.find('\t')
line=line.replace('\t',"\033[41m"+\
(8-(nPosTab-(nNP*i))%8)*' '+"\033[0m",1)
print line.replace('\n',"\033[7m \033[0m\n"),
print
The Linux users can also use piping.
For example:
python lft.py lft.py|grep range
correctly displays:
for i in range(nTab):
+ the mark of the LF (a small white rectangle)
Bye.
