Follow these steps.
1. Download Textpad from: http://www.textpad.com/download/#downloads
2. Download AutoIt from: http://www.autoitscript.com/autoit3/downloads.shtml
3. Download rundo.au3 and rundolines.au3 from: http://s281191135.onlinehome.us/2005/20050310_Stata_editor.html#script1
Save them to this folder: C:\ado\plus
4. Download stata.syn from: http://www.tc.umn.edu/~oakes007/pubh6617.htm
Save it to this folder: C:\ado\plus
5. Edit both the rundo.au3 and rundolines.au3 as follows:
5.1. Make sure the Global line has these commands:
Global $statapath, $statawin, $commands, $tempfile, $tempfile2, $dofile
5.2. Change the path to the correct Stata executable file, shown here:
$statapath = "C:\Program Files\Stata11/StataSE.exe"
OR
$statapath = "C:\Program Files (x86)\Stata10/wstata.exe"
5.3. Change the name of the Stata window to be correct, shown here:
$statawin = "Stata/SE 11.1"
OR
$statawin = "Stata/IC 10.0"
* Surprisingly, you cannot ignore this. It's not just a naming thing.
5.4. Add the line "$dofile = $CmdLine[1]" if you dont see it already:
; NOTE: Edit this block of commands to match the editor used
; EmEditor or TextPad: path of do-file is passed to AutoIt
$dofile = $CmdLine[1]
6. Open Autoit (start-programs-autoit-"Compile script to .exe"). NOTE that if you have installed SendtoToys already (or something on the big list, not sure what), you can just right-click the .au3 files to compile them that way).
6.1. Select the rundo.au3 file for the source (C:\ado\plus\rundo.au3), and click "Convert." The executable file rundo.exe is created in the folder.
6.2. Repeat step 5.1 to get rundolines.exe.
7. Open Textpad.
7.1. Click Configure-"New Document Class"
Document class name: Stata11SE <next>
Class members: *.do, *.ado, *.log <next>
Select "Enable syntax highlighting" and in the dropdown box, select stata.syn <next>
<finish>
7.2. Click Configure-preferences-tools-"Add" button. Add the programs rundo.exe and rundolines.exe to the tools.
7.3. While still in preferences, click Keyboard-Tools. Assign new shortcut keys to rundo and rundollines:
rundo: Ctrl+Shift+Q
rundolines: Ctrl+Shift+W
* Feel free to change shortcuts for your other favorite commands; I also made Ctrl-F and Ctrl-H call "Find" and "Replace", respectively, to conform to Microsoft products.
7.4. Back on the main Textpad screen, click View-Toolbars-Customize. Select Tools and click Apply.
8. Open up a sample .do file from Stata and run some commands.
9. Exit Textpad. Go to Start - Programs - and right-click Textpad in the menu. Add a shortcut key to it if you wish.
