Description

Picture splitter (picsplit) is meant to process digital camera DCIM folder in order to split contiguous files (pictures and movies) in dedicated subfolders. When 2 pictures are taken with more than an hour between them (configuration parameter), a new folder is created (folder pattern YYYY - MMDD - hhmm) to put the most recent picture in it. The file creation date is used as parameter to split the files.

Supported extension are the following :

• Image : JPG, JPEG,
• Raw : NEF, NRW, CR2, CRW
• Movie : MOV, AVI, MP4

Technology stack

1. Go is the language
2. Urfave/cli the CLI library
3. Logrus the logger

CLI Parameters

• -nomvmov : do not move movies in a separate mov folder
• -nomvraw : do not move raw files in a separate raw folder
• -delta : change the default (1h) delta time between 2 files to be split
• -dryrun : print the modification to be done without really moving the files
• -v : verbose
• -h : help

Results

Effects of picsplit are the following :

Build and test

Makefile is used to build picsplit

 make

Create a populated test folder

 etc/mktest.sh

Usage

picsplit -v -dryrun ./data
picsplit -v ./data
picsplit -v -nomvmov -nomvraw ./data

Roadmap

First release

• configurable delta
• move movies
• move raw
• dry run mode

Next releases

• merge folder command (case split too much)
• add an option to read dating data from EXIF instead of file dates
• add a console GUI
