plx

• Print command to stderr instead of stdout.

• Fix ppl command for Mac
• Added "Known issues" for ppl command on Mac

Compiled python.

PyPi package maintenance.

New experimental feature - syntax highlighting using xonsh prompt:

If you're using xonsh prompt and want to use pipeliner with syntax highlighting instead of string there is experimental
feature that catch pl @(<python>) calls and uses the expression from the xonsh python substitution as pipeliner argument.
Example:

echo echo | pl @(line + '!')
# In the xonsh prompt it's equals to:
echo echo | pl "line + '!'" 

Now you can begin the pipe from Python head:

pl "'\\n'.join(list('ABCDEFG'))" | pl "line + ('!' if num%2 else '?')" | grep '!'

B!
D!
F!

Package maintenance

Docs improvement.

Added plx and pplx commands to run execx(f"{plx_command}") most shorter way.

For example when you want to rename files you can do it Pythonic way:

$ mkdir -p /tmp/plx-test && cd /tmp/plx-test
$ touch 111 222 333 && ls
111 222 333

$ ls | plx "mv {line} prefix-{line}"
mv 111 prefix-111
mv 222 prefix-222
mv 333 prefix-333

$ ls
prefix-111 prefix-222 prefix-333

Echo example:

$ ls | plx 'echo {line} # {num}'
echo prefix-111 # 0
prefix-111
echo prefix-222 # 1
prefix-222
echo prefix-333 # 2
prefix-333

• Added ability to skip the line by returning None (NoneType). It also makes the output of pl "execx(...)" more clear.
• Added color for errors to separate lines and stack trace.

Bump package update

Added catching trivial errors

Fix dependency

Github Actions bump

Fix dependency

Added exception processing in ppl

Added showing the line that rises exception to pl:

$ echo "1;2\n3;4\nqwe" > test.txt

$ cat test.txt
1;2
3;4
qwe

$ cat test.txt | pl "line.split(';')[1]"
IndexError: list index out of range
2
4
Error line 3: qwe

Fixed multicore context

• Added multicore pipelining with ppl command
• Fix import modules before using pipeliner
