FlickSave -- automatic snapshot each time you hit save

FlickSave automagically perform an action each time you touch a watched file.

For instance, FlickSave can backup a timestamped snapshot of a file that you edit with any program, without getting in your way.

For example, each time you hit Ctrl-S within a drawing software, FlickSave will make a copy the current version of your file, along with the precise date of this version.

This may be useful for digital artists that want to prepare a time-lapse of their on-going work without having to think about it. You can even do an automatic Git commit the same way.

Usage

You should start FlickSave with the file you want to save as an argument and let it run during the time you want to let it perform your action. Once started, it will watch for modifications on the given file and, for instance, create the snapshots by himself each time something happens.

Currently, FlickSave can perform the following actions:

--save: save a timestamped snapshot of the watched file,
--inkscape: export a timestamped PNG of a watched SVG,
--git: commit the modifications of the watched file,
--log: print a message stating that the watched file was touched.

You can pass multiple actions. For instance, you can both export a PNG and do a Git commit.

By default, timestamped snapshots have the same name than the targeted file, with the addition of the timestamp. For instance, with a target file named test.svg, a snapshot will look like test_2017-11-28T21:02:59.svg.

Synopsis

flicksave.py [-h] [--save] [--inkscape] [--git] [--log] [-d DIRECTORY] [-y DELAY] [-s SEPARATOR] [-t TEMPLATE] [-w] [-v {DEBUG,INFO,WARNING,ERROR}] [-e {opened,moved,deleted,created,modified,closed}...] target

Required positional argument

target: The file to watch.

Optional arguments

-h, --help: show this help message and exit.
--save: Save a snapshot of the watched file.
--inkscape: Save a PNG snpashot of the watched SVG file.
--git: Commit the watched file if it has been modified.
--log: Print a message when the watched file is touched.
-d DIRECTORY, --directory DIRECTORY: The directory in which to copy the saved versions. (default: .)
-y DELAY, --delay DELAY: The minimum time (in seconds) between the creation of different saved files. (default: 10)
-s SEPARATOR, --separator SEPARATOR: Separator character between the file name and the date stamp. (default: _)
-t TEMPLATE, --template TEMPLATE: Template of the date stamp. (default: %Y-%m-%dT%H:%M:%S)
-e {opened,moved,deleted,created,modified,closed}..., --events: The events touching the watched file for which you want your action perfomed. You can pass multiple (space-separated) events, then the action will be performed for each of them. (default: modified)
-w, --no-overwrite: Do not overwrite snapshots created at the same time, but append a number to their name (especially useful if you watch several events).
-v {DEBUG,INFO,WARNING,ERROR}, --verbose {DEBUG,INFO,WARNING,ERROR}: Verbosity level. (default: WARNING)

Examples

Command line

Just start FlickSave with your target file as an argument:

$ ./flicksave.py --save my_file.svg

Then edit your file and save it. As usual, hit Ctrl-C (or close the terminal) to stop FlickSave.

If you want to specify a directory in which to put your snapshots, with no more than one separate file every minute:

$ ./flicksave.py --inkscape -d flicksave -y 60 my_file.svg

You may want to save both the file before and after it was modified by any program:

$ ./flicksave.py --save --events opened closed --no-overwrite my_file

If you want to see what's going on and when the action(s) are called, ask it to be more verbose:

$ touch test.txt
$ ./flicksave.py --log -v INFO test.txt &
[1] 4303
echo "." >> test.txt
2017-11-29T21:15:51 -- ./test.txt -> ./test_2017-11-29T21:15:51.txt
$ kill 4303
[1]+  Complété              ./flicksave.py -v INFO test.txt
