Setting Node properties using SlingPostServlet

SlingPostServlet is handy

To have a multi-value property that has one value, use propname@TypeHint

curl -u admin:admin -F'foo=bar' -F'foo@TypeHint=String[]' http://localhost:8888/some/path

More stuff here: http://www.unc.edu/home/adamc/post-servlet.html

And here's script that lets you set up a test page if you are using Day CQ and ExtJS

#!/bin/bash

if (( $# < 1 ))
then
    echo "Creates /apps/sandbox/*"
    echo "Usage: $0 project_name [host] [cred]"
    echo "ex, $0 test-project localhost:4502 admin:admin"
    exit 1
fi

name="$1"
host="localhost:4502"
cred="admin:admin"

if (( $# >= 2 ))
then
    host="$2"
fi

if (( $# >= 3 ))
then
    cred="$3"
fi

path="/apps/sandbox/$name"
left="http://${host}${path}"
category="sandbox.$name"

function createComponent() {
curl -s -u "$cred" \
    -F'jcr:primaryType=cq:Component' \
    -F"sling:resourceType=$path" \
    "$left" > /dev/null 2>&1
}

function uploadJsp() {
curl -s -u "$cred" \
    -T - "$left/html.jsp" > /dev/null 2>&1 <<HEREDOC

    <title>$path</title>
    <%
    final HtmlLibraryManager manager = sling.getService(HtmlLibraryManager.class);
    if (manager != null) {
        manager.writeCssInclude(slingRequest, out, "$category");
        manager.writeJsInclude(slingRequest, out, "$category");
    } else {
        out.write("BAD");
    }
    %>
</head>
<body>
    <h1>Sandbox $name</h1>
</body>
</html>
HEREDOC
}

function createWidget() {
curl -s -u "$cred" \
    -F'jcr:primaryType=cq:ClientLibraryFolder' \
    -F'sling:resourceType=widgets/clientlib' \
    -F"categories=$category" \
    -F'categories@TypeHint=String[]' \
    -F'dependencies=cq.widgets' \
    -F'dependencies@TypeHint=String[]' \
    "$left/widgets" > /dev/null 2>&1
}

function uploadJsTxt() {

    -T - "$left/widgets/js.txt" > /dev/null 2>&1 <<HEREDOC
#base=source
script.js
HEREDOC
}

function createSource() {
curl -s -u "$cred" \
    -F'jcr:primaryType=nt:folder' \
    "$left/widgets/source" > /dev/null 2>&1
}

function uploadJs() {
curl -s -u "$cred" \
    -T - "$left/widgets/source/script.js" > /dev/null 2>&1 <<HEREDOC
CQ.Ext.onReady(function() {
    //entry point
    CQ.Ext.Msg.alert('Sandbox $name', 'Hello World!');
});
HEREDOC
}

echo -n "creating cq:Component $path... "
createComponent || exit 1
echo "DONE"

lua readline tab completion

#!/bin/bash

LUA_HOME="$HOME/opt/lua"
LUA_PATH="$LUA_PATH;$LUA_HOME/?.lua" LUA_CPATH="$LUA_CPATH;$LUA_HOME/?.so" "$LUA_HOME/bin/lua" -lreadline -lcomplete $*

where readline and complete are from http://lua-users.org/wiki/CompleteWithReadline

use readline.c and complete.lua. You don't have to patch lua.c.

read http://www.lua.org/manual/5.1/manual.html#pdf-package.loaders to know how to use LUA_PATH and LUA_CPATH. question mark (?) in LUA_PATH or LUA_CPATH is replaced with foo when you do require("foo"). And, when you do require("foo.bar"), it searches for foo/bar.lua or foo/bar.so if LUA_(C)PATH.

elb-create-lb

elastic load balancing gotcha:

elb-create-lb TheNameMustBeginWithCapitalLetterAndShouldNotIncludeDotsOrUnderscore..

For example, elb-create-lb ExampleCom is ok

elb-create-lb example.com is not.
