Eu queria começar a fazer GitShots, mas no escritório eu tenho uma tela de cinema e quero que minhas fotos usem, se disponível. Este script tratará disso e de outras coisas. Isso me permite manter meus ganchos git extremamente simples, mas ainda têm muita flexibilidade.

Snap_pic Script

! / usr / bin / env ruby

# encoding: UTF-8
require 'shellwords'
require 'optparse'
require 'ostruct'
require 'pathname'

# This uses the 'imagesnap' app (brew install imagesnap)
# and this script is based off of Victor Martinez original: https://coderwall.com/p/xlatfq
# This adds the ability to tell if I am connected to my Cinema Display and if
# so then use that camera for the pic.
#
# Can then use http://www.dayofthenewdan.com/projects/tlassemble/ to create a movie
#  tlassemble ~/.gitshots Shots.mov -fps 5

# Can also use FFMPEG, but need to copy the images to a serial format.
# This will take up more disk space to produce, but the end file will be smaller than
# tlassemble
#   i=1; for f in ~/.gitshots/*.jpg; do cp -v $f "./images/$(printf '%04d' $i).jpg"; (( i ++ )); done
#   ffmpeg -r 5 -i ./images/%04d.jpg -c:v libx264 -r 15 -pix_fmt yuv420p Shots.m4v

# if for some reason your devices are different you can
# list them with `imagesnap -l`  see also http://iharder.sourceforge.net/current/macosx/imagesnap/
