gif-from-tweet

There are so many great GIFs out there and I want to have copies of them. Twitter makes that harder than it should be by converting them to MP4 and not providing access to the source material. To make it easier, I made a bash pipeline that takes a tweet URL and a filename, extracts the MP4 from that tweet and uses ffmpeg to convert back to GIF.

Dependencies

ffmpeg
- macOS: brew install ffmpeg
- Ubuntu/Debian: apt install ffmpeg

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

	#!/bin/bash
	# Author: Jay Dansand, Technology Services, Lawrence University

	# OpenSSL requires a port specification; default to 443.
	SERVER="$1:443"
	SERVER_HOST=$(echo "$SERVER" \| cut -d ":" -f 1)
	SERVER_PORT=$(echo "$SERVER" \| cut -d ":" -f 2)
	if [[ -z "$SERVER_HOST" \|\| -z "$SERVER_PORT" ]]; then
	echo "Usage: $0 host[:port] [ciphers [delay in ms]]"

	This is a tweak of https://github.com/mislav/dotfiles/blob/master/bin/tmux-vim-select-pane
	which is linked from https://github.com/christoomey/vim-tmux-navigator as a possible fix for the vim integration.

	I couldn't get the original one to work right on tmux 1.8 so I fixed it up.

	These go into tmux config file:

	bind-key -n C-h run-shell "~/tmux-vim-select-pane -L"
	bind-key -n C-j run-shell "~/tmux-vim-select-pane -D"
	bind-key -n C-k run-shell "~/tmux-vim-select-pane -U"

	#!/bin/sh

	git filter-branch --env-filter '
	OLD_EMAIL="[email protected]"
	CORRECT_NAME="Your Correct Name"
	CORRECT_EMAIL="[email protected]"
	if [ "$GIT_COMMITTER_EMAIL" = "$OLD_EMAIL" ]
	then
	export GIT_COMMITTER_NAME="$CORRECT_NAME"
	export GIT_COMMITTER_EMAIL="$CORRECT_EMAIL"

	Supported escape sequences:
	~. - terminate session
	~B - send a BREAK to the remote system
	~R - Request rekey (SSH protocol 2 only)
	~# - list forwarded connections
	~? - this message
	~~ - send the escape character by typing it twice
	(Note that escapes are only recognized immediately after newline.)
