ahknight / pdfman.sh
Created February 14, 2014 21:43
Generate a PDF of a manpage for easier/offline reading. Great for zfs/zpool manpages…
#!/bin/bash
MANFILE=$( man -w $1 $2 )
NAME=$( basename $MANFILE )
if [ -r $MANFILE ]; then
groff -mandoc $MANFILE -t | pstopdf -i -o "$NAME.pdf"
echo "wrote $NAME.pdf"
else
echo $MANFILE #Error message, probably.

ahknight / atvconvert.sh
Created March 7, 2014 15:23
Convert pretty much any video file to a format that will play on an AppleTV 3 (and maybe a 2). Only converts streams that need it.
#!/bin/bash
FILE="$1"
VCODEC=$( mediainfo --Inform="Video;%Format%" "$FILE" )
ACODEC=$( mediainfo --Inform="Audio;%Format%" "$FILE" )
echo $FILE: $VCODEC/$ACODEC
[ "$VCODEC" = "AVC" ] && VC="copy" || VC="libx264"

Downloads WWDC media. Works for 2011, 2013, and 2014. 2012 seems to break on authentication, even with the ADCDownloadAuth cookie provided. Requires BeautifulSoup4 and Requests as well as the value of your ADCDownloadAuth cookie in a JSON file in the same dir as "wwdc_cookies.json".
#!/usr/bin/env python3
import argparse
import datetime
import os
import json
import requests

Public domain. Init with a dictionary, define some properties as dynamic, serve from -valueForUndefinedKey however you wish.

ahknight / make_ios_icons.sh
Last active December 23, 2015 10:58
Given an input image as the single argument, creates all the files needed for a Universal iOS app (in the same directory, overwriting). Uses pngcrush to compress the images, but that's easily removed/commented out.
#!/bin/bash
function make_icon {
sips -s format png -Z $3 "$1" --out "$2"
pngcrush -ow -q "$2"
}
echo "Using $1 as the base image."
echo "** App Store: iTunesArtwork **"

Forward calls for a specific delegate protocol to another class for answering.
-(id)forwardingTargetForSelector:(SEL)aSelector
{
// Do we have a scroll view delegate?
if (_scrollViewDelegate && [_scrollViewDelegate conformsToProtocol:@protocol(UIScrollViewDelegate)]) {
// Is this a selector in that protocol?
struct objc_method_description methodDescription = protocol_getMethodDescription(@protocol(UIScrollViewDelegate), aSelector, NO, YES);
if (methodDescription.name != NULL) return _scrollViewDelegate;
}
return [super forwardingTargetForSelector:aSelector];
}
