# Description
__jjcli__ is a opinioned Python module that tries to simplify the creation of
__unix__ filters. It is based on:
- getopt (for command line options and args)
- fileinput (for [files/stdin] arguments)
- re (regular expressions should be native)
- csv (for csv and tsv inputs)
- urllib.request (to deal with input argumens that are url)
- subprocess
## Regular expressions
We want to have all re.* functions available (as if they were native
functions).
In order to enable __re__ flags, use: re.I re.X re.S
## Subprocesses (qx, qxlines, qxsystem)
a=qx( "ls" )
for x in qxlines("find | grep '\.jpg$'"):
...
qxsystem("vim myfile")
### Execute command return its stdout
qx(*x) → returns subprocess.getoutput(x)
### Execute command return its stdout lines
qxlines(*x) → returns subprocess.getoutput(x).splitlines()
### Execute command -- system
qxsystem(*x) → calls subprocess.call(x,shell=True)
## Other functions
slurpurlutf8(self,f)
filename = lambda s : F.filename() # inherited from fileinput
lineno = lambda s : F.lineno()
filelineno = lambda s : F.filelineno()
parno = lambda s : s.parno_ # paragraph number
fileparno = lambda s : s.fileparno_
nextfile = lambda s : F.nextfile()
isfirstline = lambda s : F.isfirstline()
close = lambda s : F.close()
