Install

Install xunter into the environment where xonsh you want to trace resides.

pip install xunter

Usage

Xunter is working as drop-in replacement of xonsh with additional arguments:

xonsh  --no-rc -c "2+2"
xunter --no-rc -c "2+2" ++depth-lt 5
#      ^^^^^^^^^^^^^^^^ ^^^^^^^^^^^^
#            xonsh         xunter

Examples:

xunter --no-rc -c "2+2" ++depth-lt 10
xunter --no-rc ++depth-lt 5 ++output /tmp/22.xunter
xunter --no-rc -c '2+2' ++filter 'Q(filename_has="main.py")'

xunter --no-rc -c 'echo 1' ++filter 'Q(filename_has="specs.py"),Q(function="run_subproc")'
# [...]/site-packages/xonsh/procs/specs.py:910:run_subproc 
#   <= xonsh/built_ins.py:206:subproc_captured_hiddenobject 
#   <= <string>:1:<module> <= xonsh/codecache.py:64:run_compiled_code 
#   <= xonsh/codecache.py:218:run_code_with_cache
#   <= xonsh/main.py:519:main_xonsh 
#   <= xonsh/main.py:470:main 
#   <= xunter/xunter:91:<module>
#   - time_sec=[0.1505]

# Don't forget about xonsh`s awesome macro call:
xunter --no-rc -c 'echo 1' ++filter! Q(filename_has="specs.py"),Q(function="run_subproc")

To set ++filter read about filters and take a look into the cookbook.

Convert log to table
