Getting started

Download

Clone the latest repository version from Github (recommended): $ git clone https://github.com/facerecog/version-merger.git

Alternatively, download the .tar.gz file from the top of this page and unpack it: $ wget https://github.com/facerecog/version-merger/tarball/master -O - | tar -xz

Now cd into the newly extracted directory.

Alternatively, install using pip: sudo pip install version-merger

How the script works

version-merger.py takes in the following parameters:

• -i: input file(s) you want to keep track of
• -o: output file
• -r: time interval (in seconds) between each snapshot
• -t: time interval (in seconds) between each merge

Every r seconds, version-merger.py uses git stash to save any changes in the input file i. Every t seconds, version-merger.py will merge all stashed content into output file o.

---

Verify that it works

Run the following script that writes a random value in dump.csv every second:
python example/randomizing_csv.py

Open a new terminal and run version-merger.py as such: python version-merger.py -i dump.csv -o mastercopy.csv -t 60 -r 1

If you have many files to track, you may use filename globbing as such:
python version-merger.py -i dump*.csv -o mastercopy.csv -t 60 -r 1

Code Example

Code Example

For the sake of brevity, this example merges its stashed versions of dump.csv every 3 seconds:

$ python version-merger.py -i dump.csv -o mastercopy.csv -t 3 -r 1
