RE: [PyCrust] 0.6 in the oven, now with PyFilling, should be done cooking soon

[Patrick K. O'B. <po...@or...>]

Richie Hindle had submitted a patch that added a lot of command history
retrieval functionality. The only part I didn't apply was saving to and
retrieving from a file. I had hoped to have a Session class developed by
now, where this functionality will ultimately reside. But I am behind
schedule. So in the mean time, you may want to look at the methods Richie
supplied. They should work with the existing code:

+     def savehistory( self, filename="PyCrustHistory.txt" ):
+         """Saves the command history to the named file, or to
PyCrustHistory.txt if no name is given."""
+         # Reverse the list so that the commands come out in chronological
order in the file.
+         commands = self.history[:]
+         commands.reverse()
+         file = open( filename, "wt" )
+         for command in commands:
+             file.write( command + "\n" )
+         file.close()
+         self.write( "History saved." )
+
+     def loadhistory( self, filename="PyCrustHistory.txt" ):
+         """Loads the command history from the named file, or from
PyCrustHistory.txt if no name is given."""
+         # Reset the history before loading up the new one.
+         self.history = []
+         self.historyPos = -1
+         file = open( filename, "rt" )
+         for command in file.readlines():
+             self.history.insert( 0, command[ :-1 ] )  # Strip the trailing
newline.
+         file.close()
+         self.write( "History loaded." )

BTW... I'm implementing some small methods for my own purposes:
def StartSavingToFile(self, filePath=None, append=false):
   """Begin saving all the code sent or written to the interpreter"""

def CloseFile(self):
   """Close the file and stop saving commands"""

def ChangeFileName(self, filePath, append=false):
   """Begins saving in a new file, copying all the info from the last
file"""

They are basically methods to save all the commands written in the
interpreter, so the user can load them from a file.
Are you interested at all ???
