 +=== Build Commands === 
 + 
 +For people using Unix, the following will be helpful for checking your JSON files for correctness. 
 + 
 +<file bash /usr/local/bin/check_json> 
 +#!/bin/sh 
 + 
 +if which python >/dev/null ; then 
 +  python -m json.tool <"$1" 2>&1 >/dev/null \ 
 +  | sed 's/^\([^:]*\): line \(.*\)/'"$1"':\2: \1/' 
 +elif which perl >/dev/null ; then 
 +  perl -MJSON -e 'local $/;decode_json(<STDIN>);' <"$1" 2>&1 >/dev/null \ 
 +  |sed 's/^\(.*\) at .e line 1, .STDIN. [^ ]* \([0-9]*\)/'"$1"':\2: \1/;' 
 +else 
 +  echo "No known JSON parsers found" >&2 
 +  exit 1 
 +fi 
 +</file> 
 + 
 +In Geany, go to the Build menu and 'Set Build Commands...' and use ''/usr/local/bin/check_json %f'' as the compile command, and ''([^:]+):([0-9]+)'' as the Error Regular Expression. 
 + 
 +=== Pretty Printing === 
 + 
 +Assuming you have Python installed, pretty printing (aka formatting) of JSON is very easy with Geany: 
 + 
 +  * Python is required (works with Python 2 and 3) 
 +  * Configure Geany: Edit->Format->Send Selection to->Set Custom Commands 
 +  * In the dialog add a new command and simply use: //python -mjson.tool// 
 + 
 +To use this, select some string in Geany and use Edit->Format->Send Selection to-><your configured command> and Geany will replace the string by the converted version. 
 +Alternatively, you can use the shortcut Ctrl-<number> in case your command is one of the first three configured commands. 
 +For details, read the [[http://www.geany.org/manual/#sending-text-through-custom-commands|documentation about Send Selection to commands]].
