I see canon passed in several places in code like
Code:
lib/python/qt5_graphics.py:392: result, seq = self.load_preview(filename, canon, unitcode, initcode)
The whole function
Code:
def load(self,filename = None):
s = self.stat
s.poll()
if not filename and s.file:
filename = s.file
elif not filename and not s.file:
return
lines = open(filename).readlines()
progress = Progress(2, len(lines))
# monkey patch function to call ours
progress.emit_percent = self.emit_percent
code = []
i = 0
for i, l in enumerate(lines):
l = l.expandtabs().replace("\r", "")
code.extend(["%6d: " % (i+1), "lineno", l, ""])
if i % 1000 == 0:
del code[:]
progress.update(i)
if code:
pass
progress.nextphase(len(lines))
td = tempfile.mkdtemp()
self._current_file = filename
try:
random = int(self.inifile.find("EMCIO", "RANDOM_TOOLCHANGER") or 0)
arcdivision = int(self.inifile.find("DISPLAY", "ARCDIVISION") or 64)
text = ''
canon = StatCanon(self.colors,
self.get_geometry(),
self.foam_option,
self.lathe_option,
s, text, random, i,
progress, arcdivision)
# monkey patched function to call ours
canon.output_notify_message = self.output_notify_message
parameter = self.inifile.find("RS274NGC", "PARAMETER_FILE")
temp_parameter = os.path.join(td, os.path.basename(parameter or "linuxcnc.var"))
if parameter:
shutil.copy(parameter, temp_parameter)
canon.parameter_file = temp_parameter
unitcode = "G%d" % (20 + (s.linear_units == 1))
initcode = self.inifile.find("RS274NGC", "RS274NGC_STARTUP_CODE") or ""
result, seq = self.load_preview(filename, canon, unitcode, initcode)
if result > gcode.MIN_ERROR:
self.report_gcode_error(result, seq, filename)
self.logger.set_depth(self.from_internal_linear_unit(self.get_foam_z()),
self.from_internal_linear_unit(self.get_foam_w()))
self.calculate_gcode_properties(canon)
except Exception as e:
print (e)
self.gcode_properties = None
finally:
shutil.rmtree(td)
if canon:
canon.progress = DummyProgress()
try:
progress.done()
except UnboundLocalError:
pass
self._redraw()
Code:
class StatCanon(glcanon.GLCanon, interpret.StatMixin):
def __init__(self, colors, geometry, is_foam, lathe_view_option, stat, random, text, linecount, progress, arcdivision):
glcanon.GLCanon.__init__(self, colors, geometry, is_foam)
interpret.StatMixin.__init__(self, stat, random)
self.lathe_view_option = lathe_view_option
self.text = text
self.linecount = linecount
self.progress = progress
self.aborted = False
self.arcdivision = arcdivision
def is_lathe(self): return self.lathe_view_option
def change_tool(self, pocket):
glcanon.GLCanon.change_tool(self,pocket)
interpret.StatMixin.change_tool(self,pocket)
# not sure if this is used - copied from AXIS code
def do_cancel(self, event):
self.aborted = True
# not sure if this is used - copied from AXIS code
def check_abort(self):
#root_window.update()
if self.aborted: raise KeyboardInterrupt
def next_line(self, st):
glcanon.GLCanon.next_line(self, st)
self.progress.update(self.lineno)
if self.notify:
self.output_notify_message(self.notify_message)
self.notify = 0
# this is class patched
# output the text from the magic comment eg: (PREVIEW,notify,The text)
def output_notify_message(self, message):
pass
Just trying to understand what's doing what and why.
