CSS Selector & XPath Expression Browser Commands

2011-08-25T00:00:00.000-07:00

CSS selectors and XPath expressions can be used to answer queries such as
- How many scripts does this page have?
- How many are external? What are they?
- How many are inline? Show me the source.

CSS Selectors - W3
"Selectors are patterns that match against elements in a tree, and as such form one of several technologies that can be used to select nodes in an XML document. Selectors have been optimized for use with HTML and XML, and are designed to be usable in performance-critical code."

Firefox and Chrome support CSS and XPath commands in the console via the Firebug Command Line API.

Syntax

$$(selector)  Returns an array of elements that match the given CSS selector.

$x(xpath)     Returns an array of elements that match the given XPath expression.

$(id)         Returns a single element with the given id.

CSS Selector Examples

//scripts

$$("script")                     //script tags

$$("script").length              //count

$$("script[async]")              //async scripts

$$("script[src]")                //external scripts with src

$$("script:not([src])")          //inline scripts with no src not

$$("script:not([src])")[0].text  //show inline script source code



//list external scripts src url

var x = $$("script[src]"); console.log("page: " + window.location.href + "\n" + x.length + " external scripts"); for(var i = 0;i < x.length; i++){console.log(x[i].src)}

2-Column Custom Format Example using Get-Alias
Dynamically format a 2-column output with N-spaces padding, based on first column width
1. get data
2. calc column 1 max length
3. calc column 2 start index
4. loop & print

$data = get-alias
$numberOfSpaces = 2
$col1MaxLength = ($data | %{$_.name.length} | measure -max).maximum  #7
$col2StartIndex = ($col1MaxLength + $numberOfSpaces)  #9

#format: 0=alias, 1=calc padding, 2=def
$data | %{"{0}{1}{2}" -f $_.name, (" " * (($col2StartIndex - $_.name.length))), $_.definition}

Debug
AliasInfo Class

#get-alias returns AliasInfo array
$data[0].gettype()  #AliasInfo : System.Management.Automation.CommandInfo

#using the measure-object cmdlet to get alias name length stats
$data | %{$_.name.length} | measure -min -max -ave -sum
count   : 137
average : 3.25
sum     : 445   #na
maximum : 7     #for this example we only need MAX
minimum : 1

elapsed 0:1:48

Log Entry
input: @
output: 2-7-2011 22:16:0:000

Log Entry with note
input: blizzard @
output: blizzard @ 2-7-2011 22:16:7:000

Notes
- Stop Timers run for the number of minutes entered, show "complete" when finished.
- Running Timers do not have a stop time, they run until you stop them.
- Input is not required for Running Timers.
- Log Entries support the ampersand char "@" and word "at".
- Bug #1
Stop Timers sometimes run past the stop time, the elapsed time is accurate, but the timer overruns the time limit.
This bug can occur if the browser thread gets backed up, etc, causing the stop-time timeout to get out of sync.
Bug sometimes occurs on iPad when tabbing to other pages.
Working on fix to check stop-time on interval instead of timeout.

Using External JavaScript Files with Google Analytics

2011-01-12T00:00:00.001-08:00

For basic page tracking, put the code in an external file.

Then you can use this

<script src="/js/googleAnalytics.js" type="text/javascript"></script>

instead of

<script type="text/javascript">
  var _gaq = _gaq || [];
  _gaq.push(['_setAccount', 'UA-XXXXX-X']);
  _gaq.push(['_trackPageview']);
  (function() {
    var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true;
    ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';
    var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s);
  })();
</script>

Add to files, right before the closing head tag.

googleAnalytics.js

var _gaq = _gaq || [];
_gaq.push(['_setAccount', 'UA-XXXXX-X']);
_gaq.push(['_trackPageview']);
(function() {
  var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true;
  ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';
  var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s);
})();

PInvoke SetWindowText PowerShell Script

2010-11-15T00:00:00.000-08:00

P/Invoke examples for the SetWindowText Windows API Function.
These examples set the window text/title for Notepad.exe.

#get notepad window handle
$notepad = get-process notepad
$notepad.mainWindowHandle  //100000, intptr structure

$pinvoke::setWindowText($notepad.mainWindowHandle, "a")

#auto-convert int to intptr
$pinvoke::setWindowText(100000, "b")

#create intptr
#out-null to suppress bool result
$pinvoke::setWindowText((new-object intPtr(100000)), "c") | out-null

$pinvoke::setWindowTextCustomWrapper(100000)

Implementation #1 simply exposes the SetWindowText method, the member definition uses C# syntax.

$pinvoke = add-type -name pinvoke -passThru -memberDefinition @'

[DllImport("user32.dll", CharSet = CharSet.Auto)]
public static extern bool SetWindowText(IntPtr hwnd, String lpString);

'@

Implementation #2, same as #1 but written on one line.

$pinvoke = add-type -name pinvoke -passThru -memberDefinition '[DllImport("user32.dll", CharSet = CharSet.Auto)]public static extern bool SetWindowText(IntPtr hwnd, String lpString);'

Implementation #3, SetWindowText is private, add custom wrapper method.

$pinvoke = add-type -name pinvoke -passThru -memberDefinition @'

[DllImport("user32.dll", CharSet = CharSet.Auto)]
private static extern bool SetWindowText(IntPtr hwnd, String lpString);

public static void SetWindowTextCustomWrapper(IntPtr handle)
{
  string customText = string.Format("handle: {0}", handle);
  SetWindowText(handle, customText);
}

Git Custom Difftool Configuration

2010-11-03T00:00:00.001-07:00

Original solution by David Tchepak: Setting up Git difftool on Windows

This example shows the configuration for ExamDiff Pro.
Tested on Windows 7 and msysgit version 1.7.3.1

1. Set the path environment variable to include "c:\program files\git\cmd\;"
2. Create a shell script wrapper file, note the forward slashes in the executable path

#c:\program files\git\cmd\diff.sh
#!/bin/sh
"c:/program files/examdiff pro/examdiff.exe" "$1" "$2" | cat

3. Edit the .gitconfig file

#c:\users\john\.gitconfig
[diff]
    tool = examdiff

[difftool "examdiff"]
    cmd = diff.sh "$LOCAL" "$REMOTE"
...

4. Verify it works, run the difftool command: git difftool --no-prompt

Checkout One File from SVN

2010-05-11T22:05:00.000-07:00

A Slik SVN/PowerShell workaround for the SVN missing feature - checking out just a few select files instead of the entire folder.

$svnFolder = 'https://dev.co.com/svn/project1'
$workingFolder = 'c:\temp\svn'
$file = 'foo.cs'

#checkout just the folder, checkout depth "only this item"
&svn checkout $svnFolder $workingFolder --depth=empty

#method 1: cd to working folder, update using file name
cd $workingFolder
&svn update $file

#method 2: update using file full path name
$file = join-path $workingFolder $file
&svn update $file

function getRegistryV1($key)
{
  $key = get-item $key
  $values = get-itemProperty $key.psPath  #gp alias for get-itemProperty
  $values
}

function getRegistryV2($key)
{
  $key = get-item $key
  $values = get-itemProperty $key.psPath
  foreach ($value in $key.property)
  {
    "$value = $($values.$value)"  #subexpression $()
  }
}

function getRegistryV3($key)
{
  $key = get-item $key
  $maxKeyNameLen = ($key.property | %{$_.length} | measure -max).maximum
  $values = get-itemProperty $key.psPath
  foreach ($value in $key.property)
  {
    "{0,-$maxKeyNameLen} = {1}" -f $value, $values.$value  #format left-aligned width
  }
}

function getRegistryV4($key)

    $filedata += "$filebreak`nfile: $_`n"
    $filedata += gc $_.fullname | out-string  #use out-string to restore linebreaks
  }
  end
  {
    $filecount = $filelist.length
    "{0} files" -f $filecount  #console - show file count
    $fileheader = "{0}`n" -f $date.toString('MM-dd-yy HH:mm:ss')
    $fileheader += "concat output file: {0}`n{1} files" -f $outFile, $filecount

Insert String Every N Characters

2010-03-31T00:24:00.000-07:00

This PowerShell v2 script inserts a string every N characters. The interval is specified using the regex repetition operator, {min,max}.

$a = 'abcdefghijklmnopqrstuvwxyz'
([regex]::matches($a, '.{1,3}') | %{$_.value}) -join ' '
([regex]::matches($a, '.{1,8}') | %{$_.value}) -join '..'
([regex]::matches($a, '.{1}') | %{$_.value}) -join '-'

#output
abc def ghi jkl mno pqr stu vwx yz

PowerShell Download File Script

2010-03-22T21:35:00.000-07:00

This script downloads files asynchronously. It uses the .NET WebClient DownloadFileAsync method.
Note that the download file path must exist.

downloadFile 'http://www.foo.com/foo.iso' 'c:\temp\foo.iso'

function downloadFile($uri, $filename)
{
  $webClient = new-object net.webclient
  $webClient.downloadFileAsync($uri, $filename)
}

JavaScript Namespaces

2010-03-15T01:10:00.000-07:00

Two variations for implementing JavaScript namespaces.
The abc namespace syntax is the simplest and useful when only public members are being wrapped.
The xyz namespace syntax can be used for public and private members.

var abc =
{
  version: '1.0',
  foo: function()
  {
    return 'abc.foo';
  }
};

var xyz = function()
{
  //private
  var _version = '2.0';
  function _foo()
  {
    return 'xyz.foo';
  }

  //public
  return {
    version: _version,  //access private var
    foo: function()
    {
      return _foo();  //access private fx
    },
    bar: function(text)
    {
      return 'xyz.bar ' + text;
    }
  };
}();  //self invoking fx

Examples

abc.foo();
abc.version;

xyz.foo();
xyz.bar('test');
xyz.version;

//output
abc.foo
1.0

xyz.foo
xyz.bar test
2.0

Object Graphs in Firebug Watch Window

A slightly modified version showing sub namespaces, eg abc.demo.foo()

var abc = {};
abc.demo =
{
  version: '1.1',
  foo: function()
  {
    return 'abc.demo.foo';
  }
};

var xyz = {};
xyz.demo = function()
{
  //private
  var _version = '2.1';
  function _foo()
  {
    return 'xyz.demo.foo';
  }

  //public
  return {
    version: _version,  //access private var
    foo: function()
    {
      return _foo();  //access private fx
    },
    bar: function(text)
    {
      return 'xyz.demo.bar ' + text;
    }
  };
}();  //self invoking fx

If you use libraries with nested namespaces, local references improve performance by minimizing member lookup.

var abcd = abc.demo;
abcd.foo();
abcd.version;

PowerShell Load Assembly Function

2009-11-29T09:20:00.000-08:00

LoadAssembly loads an assembly into the PowerShell session.

Note that unloading an assembly from PowerShell requires closing the PowerShell window, so close the window before trying to rebuild or delete a loaded assembly.

function loadAssembly($file)
{
  [system.reflection.assembly]::loadfile($file) | out-null
}

Example

loadAssembly c:\lib\file.dll

YUI Compressor for JavaScript and CSS

2009-11-27T21:50:00.001-08:00

The YUI Compressor can be used to compress JavaScript and CSS files. It also offers a low-security JavaScript obfuscation option via local symbol renaming - it does not rename functions.

The tool requires the Java SDK 1.4 or later and can be run from the command line. The command line is useful because formatted, commented JavaScript can be used for development and compressed versions can be easily generated for test and prod.

To avoid compression build errors, verify your file text encoding. For Visual Studio UTF-8, make sure to select the "Unicode UTF-8 without signature" encoding from the File - Advanced Save Options menu. Then include the charset UTF-8 option in the command.

Example - run as one line

java -jar c:\lib\yui\yuicompressor-2.4.2.jar
c:\code\web\scripts\file.js
-o c:\code\web\scripts\file.min.js
--charset utf-8

PowerShell SharpZipLib Script

2009-11-22T13:40:00.001-08:00

These PowerShell scripts can be used to zip and unzip files.

Zip operates on file lists such as output from the Get-ChildItem cmdlet. You can set the zip file root folder by specifying the leading folder path to remove. The Where-Object cmdlet can be used for advanced filtering. This function does not zip empty folders. See the SharpZipLib wiki for examples of zipping empty folders. Also, this function does not work with files that are locked, such as log files that are being written.

The free SharpZipLib .NET Zip assembly is used for zip functionality. You'll need to download the assembly and load it into PowerShell to run the scripts. Note that after you download or copy the assembly locally, you may have to trust the assembly. To do this, right-click the assembly and trust (unblock) it. Other related info can be found the SharpZipLib wiki.

These PowerShell scripts were tested using SharpZipLib version 0.85.5.
Strong name: ICSharpCode.SharpZipLib, Version=0.85.5.452, Culture=neutral, PublicKeyToken=1b03e6acf1164f73

function zip($zipFile, $leadingFolderPathToRemove)
{
  begin
  {
    $zip = [icSharpCode.sharpZipLib.zip.zipFile]::create($zipFile)
    $zip.beginUpdate()
  
    #add trailing backslash if necessary
    $leadingFolderPathToRemove = (join-path $leadingFolderPathToRemove '\')
  }
  process
  {
    #remove leading folder path from file name
    $file = $_.fullName.remove(0, $leadingFolderPathToRemove.length)
    $zip.add($_.fullName, $file)
  }
  end
  {
    $zip.commitUpdate()
    '{0} files zipped' -f $zip.count
    $zip.close()
  }
}

function unzip($zipFile, $unzipToFolder)
{
  $zip = new-object icSharpCode.sharpZipLib.zip.fastZip
  $zip.extractZip($zipFile, $unzipToFolder, $null)
}

Examples

loadAssembly c:\lib\sharpZipLib\ICSharpCode.SharpZipLib.dll

#zip all files from folder c:\code\web\ into c:\temp\web.zip

PowerShell Find Files Script

2009-11-15T19:58:00.000-08:00

FindFiles returns a list of files that contain the search text. The search can be plain text or a regular expression.

This function is similar to using the Select-String cmdlet with the -list switch parameter. The difference is that FindFiles supports searching across line breaks. See the examples that use the "dot matches line breaks" regex pattern (?s).

function findFiles($text)
{
  begin
  {
    $count = 0
  }
  process
  {
    $data = [system.io.file]::readAllText($_.fullname)
    if ($data -match $text)  #if matches at least once...
    {
      $_.fullname
      $count += 1 
    }
  }
  end
  {
    "$count files found"
  }
}

Examples

#find files containing "abc"
gci c:\* -include *.txt | findFiles 'abc'

#find files containing "abc" or "xyz"
gci c:\* -include *.txt | findFiles 'abc|xyz'

#find files containing "abc", including across line breaks
gci c:\* -include *.txt | findFiles '(?s)a.*bc|ab.*c'

#find files containing "<abc>" tags, including across line breaks, and empty tags
gci c:\* -include *.txt | findfiles '(?s)<abc>.*</abc>|<abc/>'

Hash Functions

2009-08-19T19:55:00.000-07:00

GetHash returns the hash value of a byte array.
GetHashStr returns the hash value of a string.

These functions can use any of the hash classes from the System.Security.Cryptography namespace, e.g. MD5, SHA1, SHA256, SHA512.

//C#
using System;
using System.Security.Cryptography;
using System.Text;

namespace ExpressionSoftware.Security.Crypt
{
    public static class Hash
    {
        public static byte[] GetHash(byte[] bs, Type hashType)
        {
            return HashAlgorithm.Create(hashType.Name).ComputeHash(bs);
        }
        
        public static byte[] GetHashStr(string input, Type hashType)
        {
            byte[] bs = Encoding.UTF8.GetBytes(input);
            return GetHash(bs, hashType);
        }
    }

GetFileHash returns the hash value for a file. The hash type can be any hash class from the System.Security.Cryptography namespace, e.g. MD5, SHA1, SHA256, SHA512.
CompareFileHash returns true if the files have the same hash.
CompareFileHashInfo returns the hash comparison information.
GetFileHashObject returns a file hash wrapper object.

function getFileHash($file, $hashType)
{
  $stream = new-object io.streamReader $file
  $hash = $hashType::create().computeHash($stream.baseStream)
  $stream.close()
  trap
  {
    if ($stream -ne $null)
    {
      $stream.close()
    }
    break
  }
  [string] $hash
}

function compareFileHash($file1, $file2, $hashType)
{
  (getFileHash $file1 $hashType) -eq (getFileHash $file2 $hashType)
}

function compareFileHashInfo($file1, $file2, $hashType)
{
  $f1 = getFileHashObject $file1 $hashType
  $f2 = getFileHashObject $file2 $hashType

  $f1
  $f2
  "Hash Type: " + $hashType.name
  "Duplicate Files: " + ($f1.hash -eq $f2.hash)
}

function getFileHashObject($file, $hashType)
{
  $fileHash = new-object psObject
  $fileHash | add-member noteProperty file $file
  $fileHash | add-Member noteProperty hash (getFileHash $file $hashType)
  return $fileHash
}

Examples

>> $hashType = [system.security.cryptography.MD5]
>> getFileHash c:\file1.txt $hashType
   52 85 168 127 81 223 163 157 187 191 244 34 221 99 48 201

Adding Silverlight to an Existing Website

2009-01-15T12:20:00.000-08:00

Minimum requirements for adding a Silverlight 2.0 application to an existing website.

These requirements are specific to ASP.NET ASPX pages. We'll review the requirements for HTML pages in another post.

1. Add a Silverlight assembly reference to the website
Path: c:\program files\microsoft sdks\silverlight\v2.0\libraries\server\system.web.silverlight.dll

2. Register the Silverlight assembly controls in the web.config or the page
Registering in the web.config eliminates having to use a Register directive on each page.

//web.config
<pages>
    <controls>
        ...
        <add tagPrefix="asp" namespace="System.Web.UI.SilverlightControls" assembly="System.Web.Silverlight, Version=2.0.5.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
    </controls>
</pages>

//page
<%@ Register TagPrefix="asp" Namespace="System.Web.UI.SilverlightControls" Assembly="System.Web.Silverlight, Version=2.0.5.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" %>

3. Add the Silverlight application to the website
Add the Silverlight application XAP file to the website, e.g. \silverlight\silverlightApp.xap

4. Add the Silverlight application control to a new or existing page
Additionally, an AJAX ScriptManager control is required in the Master page or the actual page itself.

<%@ Page Language="C#" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Silverlight Demo</title>
</head>
<body>
    <form id="form1" runat="server">
        <asp:ScriptManager ID="scriptManager" runat="server"/>
        <div style="height:100%;">
            <asp:Silverlight ID="silverlightControl" runat="server"
              Source="~/silverlight/silverlightApp.xap" 
              MinimumVersion="2.0.31005.0" 
              Width="100%" Height="100%"/>
        </div>
    </form>

Debugging Silverlight - Reading Files from Isolated Storage

2009-01-10T11:02:00.000-08:00

If you need to read a data file during a Silverlight debug session, you'll have to work around the Silverlight security model which limits file IO to isolated storage.

One option is to use a file upload dialog, another is to identify the isolated storage folder, copy the file to the store, and then just read it.

The trick to identifying the isolated storage folder is to use the IsolatedStorageFile.RootDirectory property. This property is private, but accessible while debugging.

The Silverlight utility class below has a DebugRootDirectory() method that can be used for this purpose. Simply call the DebugRootDirectory() method and the code will automatically stop on the programmatic breakpoint. At that point, you can inspect the store and get the value.

The class has a number of other related utility methods.

using System;
using System.Diagnostics;
using System.IO;
using System.IO.IsolatedStorage;

namespace ExpressionSoftware.Silverlight.Utility
{
    public static class IsolatedStorage
    {
        public static void DebugRootDirectory()
        {
            using (IsolatedStorageFile store = IsolatedStorageFile.GetUserStoreForApplication())
            {
                Debugger.Break();
                //inspect store variable here, get the isolated storage folder path from private RootDirectory property
                //store.RootDirectory
            }
        }

        //Read a file from Isolated Storage.
        //The file path parameter must specify the full path, use the DebugRootDirectory() method
        //to get the isolated storage folder path.
        public static string ReadFile(string filePath)
        {
            using (IsolatedStorageFile store = IsolatedStorageFile.GetUserStoreForApplication())
            {
                Debug.Assert(store.FileExists(filePath), "File does not exist in Isolated Storage.");
                using (StreamReader reader = new StreamReader(store.OpenFile(filePath, FileMode.Open, FileAccess.Read)))
                {
                    return reader.ReadToEnd();
                }
            }
        }

        //Default quota is 1MB.
        public static long GetStoreQuota()
        {
            using (IsolatedStorageFile store = IsolatedStorageFile.GetUserStoreForApplication())
            {
                return store.Quota;
            }
        }

        public static long GetAvailableFreeSpace()
        {
            using (IsolatedStorageFile store = IsolatedStorageFile.GetUserStoreForApplication())
            {
                return store.AvailableFreeSpace;
            }
        }

        //Default quota is 1MB.
        //The new quota must be larger than the old quota or an exception will be thrown.
        public static bool IncreaseQuota(long newQuotaSize)
        {
            using (IsolatedStorageFile store = IsolatedStorageFile.GetUserStoreForApplication())
            {
                return store.IncreaseQuotaTo(newQuotaSize);
            }
        }
    }
}
