There doesn't seem to be anyway of doing an attachment, so I've got a cut down version of PfrankUser.py below in the code section.

I tested it with a variety of date formats from files I downloaded from the net. It is VERY flexible on recognising dates, all the following dates are handled correctly (as well as many more).

"Date 2nd July 1967 test",
"Date July-2-1967 test",
"Date Jul 1967 test",
"september-5-43",
"sep 1943",
"5 sept 43",
"Date 17-12-2007 test",
"(1967-07-02) # What the end result should be",
"171207",
"1943 # Not a valid date",
"1943 until 1945-11 # Not a valid date, followed by valid one",
"198507 #YYYYMM",
"July 1st 1961 to 2nd July 1967 # Multiple dates",

You can change the output format by selecting the View \ Options \ Date Formatter. I have added a few small extensions, the month can be a season, or a two month span. So the following are valid dates.

"Christmas 2001",
"Fall 2000",
"March-April 1999",

On outputting the dates if you use month names then the extended forms are used, so format string of %Y %b for the last item in the list above would give 1999 Mar-Apr, and %B %y would give March-April 99. For the extended form of months there is no day field. The extended months have default numeric value associated with them so Christmas 2001 would be 2001-12, Fall 2000 gives 2000-09 and March-April 1999 gives 1999-03 if you are using a numeric format.

Sometimes the day is not available and so there is an extension in the output, and you can use ~ to only display that if day is present. So using an output of Y%-%m~-%d with an input of July 2 1967 would give 1967-07-02, but for an input of July 1967 it would give 1967-07.

I tried loading the PFrankUser.py excerpt that you provided and it doesn't compile due to these lines:

=====================
else :
year = int (arg3)
if arg4 != '' :
year = year * 100 + int (arg4)
elif year <20>= 0:

if (sep2 != sep1) & (self.ordinal.match(arg1) == None) :
append2nd = True
else :
day = self.getInt (arg1)
year = int (arg3)

if arg4 != '' :
year = year * 100 + int (arg4)
elif year < 20 :
year = 2000 + year
else :
year = 1900 + year
else :
=========================

I would like to try out the file. Would you please send me a copy via email.

Thanks,

Peter.

Did you get chance to look at my modified file? If you want to modify it, or include it feel free. (You might want to tidy it up though Wink

)

And what do you think of my idea of 2 pass renaming, so that you can see all the files to be processed and then come up with a naming scheme for that.

I didn't receive any modified file.
Yes - I would like to try it and save it. If other people send me their User files, then I can make those available for all in the future.

Don't know what you mean by the 2 pass renaming. Each row of the custom renaming panel already acts like a renaming pass.

I sent another email to you (to the other email address).

When I was talking about 2 pass renaming I was talking about the following.

If I have a selection of files, that when processed give Photo 17, Photo 21, Photo 100, Music 1, Music 10, I would like it to rename them to Photo 017, Photo 021, and Photo 100, Music 01, Music 10. I know how to do a rule to rename n digits to m digits, but I want to write a user command that automatically detects the highest value used for each name, and then pads the other names to match.

Another thing that will use the same code is to automatically move files into subdirectories, so that in the example above it would create Photo and Music directories and move the files into those directories (but only if more than a certain threshold of files was reached).

I also plan on adding something to allow you to automatically prepend then directory name to all the files (and another to move them up in the directory structure). So you could have music\Beetles\Hard Days Night.mp3 and the first command would rename Hard Days Night.mp3 to Beetles - Hard Days Night.mp3, and then the other command would move that file into the music directory.

Thanks - I received the email.

If I understand your 2-pass renaming idea correctly I think it is already there. i.e. Each row of the custom renaming list is like a pass of renaming.
For example you can insert your user-defined DateFormatter command into row 1 of the list. You can then insert your upcoming user-defined command which move files to Photo and Music folders into row2. Both of those commands can be coded into the PFrankUser.py file and appear as separate commands in the pre-defined drop-down list.

You could add another command into the PFrankUser.py file to prepend folder names; that command can be inserted into row 3. If you weren't looking for the threshold, you could instead add the existing pre-defined command for inserting folder names into row 3. There is also a pathbuilder option for regular expressions which can be used to move the files into different folders (could insert into row 4).
More rows with predefined ocmmand or regex search/replace could be used to do final tweaking like removing uinwanted characters, removing excess blank characters, fixing capitalizations, etc.

Hope this helps,

Peter.

You can almost do what I want. But I want it to find all the titles with numbers in them and decide how many digits are needed for each title individually. You need a 2nd pass to do that. Ie Photos (1967) 1, Photos 10 (1973) , Photos_100. After processing through some rules you get Photos 1 (1967), Photos 10 (1973), Photos 100. I want it to say I need 3 digits for the number so that it would become Photos 001 (1967), Photos 010 (1973), Photos 100. If there were just those three files in the directory, it would also know that it doesn't need to move them to a subdirectory. But if you also had Music 1, Music 2, Music 3 then it would decide to create 2 subdirectories, one called Photos and one called Music, it would move the files into the appropriate subdirectories. I want to make it as automated as possible Smile

rather than selecting and deselecting rules (I already have a rule to change 3 digit number to 4 digit number) which I select before running the rules.

OK - I see what you are after.
There is already a post-processing flag for a regex row.
Not sure if there is an easy way to add this functionality for user-defined (or predefined) commands. I'll have to think about it.

One alternative is to use 2 renaming lists. Use the first list to do the post-processing which uses a user-defined command to determine how many digits you need and store that info using a variable in PFrankUser.py. Then use the second list to call the remaining commands, the first of which would use the variable to convert numbers to their required number of digits.

I've had alook at this and have 2 possible solutions.

1)
I adapted the postprocessing available for regex lines to also be available for pre-defined commands (which includes user-defined commands). I still have to test it and decide on a syntax for pre-defined flags. This will be available sometime in the future. However, this is really meant to do post-processing after all the duplication checking. What you really need is preprocessing.

2)
For preprocessing you can use the already available initforscan function which is defined for all user-defined commands. This is currently called once before the scanning starts. I am going to rearrange the scanner so that this function is called just after obtaining the initial list of names using the name filters. The name list will be made available as a global variable which you can access.
Then in the initforscan for your user-defined dateformatter (or perhaps some new user command), you can prescan all the names and determine how large a number field you will need and how many names would be changed. then the regular processing would commence with all the new information.
Does that sound like it could work for you?
If so, I can have a beta program ready tomorrow.

That sounds good thanks, I will be making a new command. I'm already working on another new one that will prepend directory name to the file names (it's a LOT more complex than that though). If you have a directory called Music To Die For\ and files called Music To Die For 1.mp3 MTDF 2.mp3, 3.mp3, then it will rename MTDF 2 and 3.

A beta is available at:

http://www3.telus.net/pfrank/PFrankSetup2.111.exe

It has the global scanlist that you can access in your PFrankUser.py file using the initforscan function. The variable is in 'configurator.scanlist'. The example below prints the list:

===================================
def initforscan(self, VerificationTest=False) :
"""
This function is called whenever a new scan or rescan is made. Use it to
reset anything that needs to be reinitialized before a scan.
This function is mandatory.
"""
print "scan list is: ", configurator.scanlist
===================================

This is the list of names that have passed the name filtering. You should be able to process the list to determine how many digits your numbers need, etc.

Let me know if there are any problems

Peter.
