My perl-based `jq` replacement
echo -n '{"a":5,"b":7}' | jsonmap -r '$_->{"a"}." and ".$_->{"b"}'
#!/usr/bin/perl
# usage: $0 [options] <perlcode> [<inputfile>]
#
# reads json from stdin/inputfile, or if -R given, reads whole input as a string
# perlcode gets the json/string as a perl object in $_
# return object from perlcode is encoded as json to stdout, or passed as-is if -r given
# pretty-printed by default, -c for compact
# all input/output is in UTF-8

Handy script for generating a github "diff" url between two refs

Example:

$ github-diff origin/master 04ed4b
https://github.com/example/repo/compare/a418bcece3d540ad1d4864030635c2d4ae2628b3...04ed4b34bee0a2b2003f3744b772473a4c8b604b

Requires the commits to be available locally, so you might have to git fetch first.

Using IntelliJ UI Designer for creating Swing forms in the Ceylon (1.3.0) language

I wanted to create a Swing app in Ceylon and figured I'd give using the UI designer a shot. Here are the necessary steps to get it to work:

Steps

Change IDEA settings

  • From the menu: File -> Settings
  • Navigate to Editor / GUI designer
  • Make sure "Generate GUI into:" has Java source code selected
  • Change "Default accessibility for UI-bound fields:" is something else than "private", for example package-private
  • Click OK to save

How to set up a remote (non-bare) Git repository with read-only checkout of some branch to automatically update on push. This assumes you have already created a regular repository in the remote location already; typically just "git init".
cat > .git/hooks/post-receive <<EOF
#!/bin/bash
set -e
cd ..
unset GIT_DIR
git reset --hard HEAD --
# put any additional cleanup/reload commands here
EOF
chmod ug+rx .git/hooks/post-receive

Forward X DISPLAY over "sudo su - <user>", for example after ssh:ing to server
username=<user> ; echo -n "xauth add `xauth list :${DISPLAY#*:}`" | sudo su - $username ; sudo su - $username ; echo -n "xauth remove :${DISPLAY#*:}" | sudo su - $username

git tweak-index - tweak/edit files in index without touching the checked out versions

git tweak-index

This git add-on command lets you tweak/edit files in the index/stage directly without touching the checked out working copy.

  • Use case 1: So you accidentally git-added some changes that you didn't want to merge just yet and would like to partially undo?
  • Use case 2: You want to make a quick commit to some file(s) but keep the checked out version(s) as-is?
  • Use case 3: You have been trying to use git reset -p but failed spectacularly?
  • Use case 4: You want to stage something that is not an interpolation of the checked out and the committed version?
