How to silence $XONSH_SHOW_TRACEBACK help text?

[rpdelaney]

xonsh: For full traceback set: $XONSH_SHOW_TRACEBACK = True

I get this every time there's a shell error. I know about it and I don't need to be reminded. How can I silence this help text?

You can add to your ~/.xonshrc:

$XONSH_SHOW_TRACEBACK = False
# or
$XONSH_TRACEBACK_LOGFILE = '/dev/null'

Example:

xonsh --no-rc
raise Exception(1)
# xonsh: For full traceback set: $XONSH_SHOW_TRACEBACK = True
# Exception: 1

$XONSH_TRACEBACK_LOGFILE = '/dev/null'
raise Exception(1)
# Exception: 1

$XONSH_SHOW_TRACEBACK = True
raise Exception(1)
#Traceback (most recent call last):
#  File "<stdin>", line 1, in <module>
#Exception: 1

Here is the logic in the code:

xonsh/xonsh/tools.py

Lines 963 to 972 in cbf23e6

	def print_warning(msg):
	"""Print warnings with/without traceback."""
	manually_set_trace, show_trace = _get_manual_env_var("XONSH_SHOW_TRACEBACK", False)
	manually_set_logfile, log_file = _get_manual_env_var("XONSH_TRACEBACK_LOGFILE")
	if (not manually_set_trace) and (not manually_set_logfile):
	# Notify about the traceback output possibility if neither of
	# the two options have been manually set
	sys.stderr.write(
	"xonsh: For full traceback set: " "$XONSH_SHOW_TRACEBACK = True\n"
	)

If XONSH_SHOW_TRACEBACK is manually set to False then the help text is not printed. My problem was that I was setting it like this:

XONSH_SHOW_TRACEBACK=False

...when I should have done this:

$XONSH_SHOW_TRACEBACK=False
