Versioned Backup Files

Post by jussij »

The code below should be saved to the versions.py file in the following Zeus zScript folder:

Code: Select all

C:\Users\<user Id>\AppData\Local\Programs\Zeus\zScript\versions.py
For details on how to use the script refer to the comments found in the macro itself.

The code represents the latest iteration of this versions.py file and it includes changes from the discussion thread found below.

# Name: Versioned Backup Files Macro
#
# Original Author: Jussi Jumppanen
#
# Current Author: WilsonDevo (Modified) (this version)
#
# Language: Python Macro (V3.x - Does not work with Python V2.x)
#
# Description: This macro creates a time stamped backup of the file every time the file is saved.
#
#              To configure this macro, for all document types, use the Options, Default Document Type menu
#              and attach the macro to the "File Save Prefix" trigger option. (e.g.)
#
#                  Options|Default Document Type...|Triggers|File Save Prefix = $zud\zScript\versions.py
#
#              To configure this macro, for a particular document type, use the Options, Trigger Options menu
#              and attach the macro to the "File Save Prefix" trigger option. (e.g.)
#
#                  Options|Trigger Options...|File Save Prefix = $zud\zScript\versions.py
#
#              The time stamped backups are created using one of six possible backup modes and are controlled by
#              the 'BACKUP_MODE' and 'BACKUP_DIR' strings. The different backups modes are listed below using examples.
#
#              The most fine grained backup directory location includes the week number of the month (BACKUP_MODE=01 or 02)
#              or the day of the month (BACKUP_MODE=03 or 04) in an attempt to make managing the backups easier.
#
#              For example, old backups beyond a certain age can be quickly identified and deleted using their directory name
#              as an indication of their age rather than sifting through the time stamped backup files using either their
#              filename or their file date as a selector. (e.g. I can quickly delete all Python (.py) time stamped backup files
#              created in April 2017, because they are now redundant, just by deleting the '...\.py\2017\Apr\...' directory.)
#
#              Being able to locate a particular time stamped backup file easily, in times of high stress, is also much easier with
#              a logical hierarchical backup directory structure.
#
#              (The simplest backup mode is BACKUP_MODE=8 but this means that the time stamped backups are created in a
#              a sub-directory of the current file's directory. If the current file's directory is accidentally deleted then
#              all of the time stamped backups will also have been deleted. Each backup scheme will have its own pros and cons, however.)
#
#              By default the backups are written to this folder:
#
#                   C:\Users\<User Id>\EDITOR_BACKUPS\ZEUS_BACKUPS\TIME_STAMPED\

Re: Versioned Backup Files

Post by wilsondevo »

The Python 2.x code listed in the CODE panel is called 'Zeus_Versioned_Backup_V397.py' and is a modified version of the original 'Versioned Backup Files Macro' macro script and can be used with Zeus versions such as Zeus V3.97j.

The original 'Versioned Backup Files Macro' was initially tried with Zeus V3.98j but this version of Zeus uses Python 3.6 and the original macro code was not compatible.

The original Python 2.x macro code was then converted to a Python 3.6 version and is listed in a subsequent reply.

After the conversion was performed a comparable Python 2.x version was then also created to match the new Python 3.6 version, since some other usability mods were introduced into the new version for my own versioned backup scheme requirements.

Summary

'Zeus_Versioned_Backup_V397.py' - Python 2.x version for use with Zeus V3.97j (this reply)

'Zeus_Versioned_Backup_V398.py' - Python 3.x version for use with Zeus V3.98j (next reply)

I hope this may be of some use to Zeus users concerned with maintaining versioned backups.

# Name: Versioned Backup Files Macro
#
# Original Author: Jussi Jumppanen
#
# Current Author: WilsonDevo (Modified) (this version)
#
# Language: Python Macro (V2.x - Does not work with Python V3.x)
#
# Zeus Usage: V3.97j (using C:\Program Files (x86)\Zeus\python26.dll) (e.g.)
#
# Description: This macro creates a time stamped backup of the file every time the file is saved.
#
#              To configure this macro for all document types use the Options, Editor Options menu
#              and in the Triggers section attach the macro to the "File Save
#              Prefix" trigger option. (e.g.)
#
#              Options|Editor Options...|Triggers|File Save Prefix = $zud\zScript\Zeus_Versioned_Backup_V397.py
#
#              The backups are saved as per the following scheme (e.g.)
#
#              Original file:           C:\Users\frank\work\ShoppingList.txt
#
#              Time-stamped backup:     C:\Users\frank\EDITOR_BACKUPS\ZEUS_BACKUPS\TIME_STAMPED\ShoppingList__17-Jun-2017__081623.txt
#              (created by this script and only when the file has been modified)
#
#              Non time-stamped backup: C:\Users\frank\EDITOR_BACKUPS\ZEUS_BACKUPS\ShoppingList.txt
#              (created by Zeus itself if it has been enabled in Options|Editor Options...|Backup)
#
#              The non time-stamped backup, if enabled, provides an extra file backup and represents
#              the most 'current backup'.

#
#       The time stamped backup files are stored in one single global directory rather than in the currently edited file's
#       directory in order to make finding and managing the time stamped backups easy.

# Name: Versioned Backup Files Macro
#
# Original Author: Jussi Jumppanen
#
# Current Author: WilsonDevo (Modified) (this version)
#
# Language: Python Macro (V3.x - Does not work with Python V2.x)
#
# Zeus Usage: V3.98j (using C:\Program Files (x86)\Zeus\python36.dll) (e.g.)
#
# Description: This macro creates a time stamped backup of the file every time the file is saved.
#
#              To configure this macro, for a particular document type, use the Options, Trigger Options menu
#              and attach the macro to the "File Save Prefix" trigger option. (e.g.)
#
#              Options|Trigger Options...|File Save Prefix = $zud\zScript\Zeus_Versioned_Backup_V398.py
#
#              The backups are saved as per the following scheme (e.g.)
#
#              Original file:           C:\Users\frank\work\ShoppingList.txt
#
#              Time-stamped backup:     C:\Users\frank\EDITOR_BACKUPS\ZEUS_BACKUPS\TIME_STAMPED\ShoppingList__17-Jun-2017__081623.txt
#              (created by this script and only when the file has been modified)
#
#              Non time-stamped backup: C:\Users\frank\EDITOR_BACKUPS\ZEUS_BACKUPS\ShoppingList.txt
#              (created by Zeus itself if it has been enabled in Options|Editor Options...|Backup)
#
#              The non time-stamped backup, if enabled, provides an extra file backup and represents
#              the most 'current backup'.
#
#              See the code below for more info on configuring this backup scheme

# Note: The time stamped backup IS NOT created when a 'FileSaveAll' or 'FileSaveAllNamed' operation is performed.
#
##############################################################################################################################################
#
# Note: This script over time could generate hundreds of time stamped backup files but since Zeus is often used to

#       since individual program code files are generally not large in size.
#

Re: Versioned Backup Files

Thanks for this much improved backup macro :)

I've taken your version, made a few minor changes (added a comment, try/catch and handling files with spaces) and that version shown below has been added to the official Zeus installer:

No worries Jussi.

Glad to contribute something to the amazing Zeus editor !

Just for completeness, here is the old Python 2.x version of the backup script incorporating your subsequent mods
for any Zeus users who may be still using an old V3.97 version.

Re: Versioned Backup Files

Post by wilsondevo »

This is a more elaborate Python 2.x version of the versioned backup script incorporating eight different backup modes.

Each backup mode stores the time stamped backup file in a directory conforming to a particular file extension and/or date hierarchy.

Choose the backup mode that suits your needs or create your own by modifying the Python script.

Summary

'Zeus_Versioned_Backup_V397.py' - Python 2.x version for use with Zeus V3.97j (this reply)

#
# Name: Versioned Backup Files Macro
#
# Original Author: Jussi Jumppanen
#
# Current Author: WilsonDevo (Modified) (this version)
#
# Language: Python Macro (V2.x - Does not work with Python V3.x)
#
# Zeus Usage: V3.97j (using C:\Program Files (x86)\Zeus\python26.dll) (e.g.)
#
# Description: This macro creates a time stamped backup of the file every time the file is saved.
#
#              To configure this macro, for all document types, use the Options, Editor Options menu
#              and in the Triggers section attach the macro to the "File Save Prefix" trigger option. (e.g.)
#
#                 Options|Editor Options...|Triggers|File Save Prefix = $zud\zScript\Zeus_Versioned_Backup_V397.py
#
#              The time stamped backups are created using one of six possible backup modes and are controlled by
#              the 'BACKUP_MODE' and 'BACKUP_DIR' strings. The different backups modes are listed below using examples.
#
#              The most fine grained backup directory location includes the week number of the month (BACKUP_MODE=01 or 02)
#              or the day of the month (BACKUP_MODE=03 or 04) in an attempt to make managing the backups easier.
#
#              For example, old backups beyond a certain age can be quickly identified and deleted using their directory name
#              as an indication of their age rather than sifting through the time stamped backup files using either their
#              filename or their file date as a selector. (e.g. I can quickly delete all Python (.py) time stamped backup files
#              created in April 2017, because they are now redundant, just by deleting the '...\.py\2017\Apr\...' directory.)
#
#              Being able to locate a particular time stamped backup file easily, in times of high stress, is also much easier with
#              a logical hierarchical backup directory structure.
#
#              (The simplest backup mode is BACKUP_MODE=8 but this means that the time stamped backups are created in a
#              a sub-directory of the current file's directory. If the current file's directory is accidentally deleted then
#              all of the time stamped backups will also have been deleted. Each backup scheme will have its own pros and cons, however.)

This is a more elaborate Python 3.x version of the versioned backup script incorporating eight different backup modes.

Each backup mode stores the time stamped backup file in a directory conforming to a particular file extension and/or date hierarchy.

Choose the backup mode that suits your needs or create your own by modifying the Python script.

Thanks for this updated macro :)

I've included this latest version into the official Zeus installer.

Cheers Jussi

Re: Versioned Backup Files

Post by wilsondevo »

Hi Jussi,

I have added the following line to the Python 2.x and Python 3.x versions of the backup script.

Code: Select all

        if  current_dir != "": shutil.copy2(fullfilename, backup_filepath)
This was needed to avoid an exception that was being generated when a new file was created (e.g. 'untitled.txt'), some new content was added and then it was saved.

Since the 'untitled.txt' file has been created within the Zeus session with 'Create a new document', then it does not have a 'current_dir' yet, so the 'shutil.copy()' command fails.

The first versioned backup of the new file will be created when it is saved for the second time.

Cheers - WilsonDevo

While using your macro I did run into this issue.

I fixed this with the following code change towards the top of the macro ;)

Code: Select all

    # this macro expects to be passed at least two arguments
    if zeus.argc() < 2: return

    # ignore any un-named files
    if not zeus.is_named(): return
Cheers Jussi
