shorter version of batch file: getting directory and parent directory

Posted by jpluimers on 2013/08/17

Two years ago, I posted a batch file that gets the parent directory of the batch file that runs.

It was convoluted, using substrings and intermediate environment variables so you needed setlocal.

This one does not any more: for both the directory of the batch file, and the parent directory of that directory, one-liners suffice:


echo batchfile=%0
echo full=%~f0
setlocal
for %%d in (%~dp0.) do set Directory=%%~fd
echo Directory=%Directory%
for %%d in (%~dp0..) do set ParentDirectory=%%~fd
echo ParentDirectory=%ParentDirectory%
endlocal

command line – create empty text file from a batch file (via: Stack Overflow)

Posted by jpluimers on 2013/08/15

StackOverflow has [WayBack] quite a [WayBack] few questions [WayBack] on creating [WayBack] empty text files from a batch file.

Most answers involve the [WayBack] NUL special file (which is not available on one special version of Windows [WayBack] Windows Fundamentals for Legacy PCs, but can easily be retrofitted).

[WayBack] This is the solution I use most often:

type NUL > EmptyFile.txt

Remove the first 3 characters in var in batch file (via: Stack Overflow and Rob van der Woude)

Posted by jpluimers on 2013/08/13

Getting substrings in a batchfile requires you to use the %…:~…% syntax as explained by Rob van der Woude.

Note this only works on batch file variables, so not on batch/function arguments (%1, %2, …)and for-loop indexes (%%f, etc).

This code gets the leftmost three characters of var:

set var=%var:~3%
echo %var%

Getting a fresh root hint file on SUSE 12.x

Posted by jpluimers on 2013/07/31

Wrote a small script that goes into my monthly crontab.

It gets ftp://ftp.internic.net/domain/named.cache into /var/lib/named/named.cache.new, and logs when you need to copy it over into /var/lib/named/root.hint

PowerShell: fixing script signing errors even after you had “Set-ExecutionPolicy RemoteSigned”

Posted by jpluimers on 2013/06/27

CodeRage Mobile day 2 QA

Posted by jpluimers on 2013/06/19

I had a bit of trouble getting into CodeRage Mobile: somehow the confirmation email never reached the pluimers.com servers. After retrying today, @EmbarcaderoTech sent a GotoMeeting link that worked.

Later I will try to trace back about the mail issue (:

I’m in now, and since I usually loose the QA information, here is a dump of the QA for today so far.

Will try to find time for post editing and getting the URLs clickable.

Delphi XE4: installer batch file for “experimental GExperts + code formatter for Delphi XE4”

Posted by jpluimers on 2013/06/12

Slightly more than a month ago, Thomas Müller release the experimental GExperts + code formatter for Delphi XE4.

Since there is no official GExperts for Delphi XE4 build yet, his installation instructions include this:

Use the ExpertManager tool to register GExperts to Delphi XE4.

The thing is: ExpertManager is part of GExperts, so this introduces a “chichen-and-egg” situation.

So I wrote a small batch file and a bit of documentation to install it.

Just in case you cannot download that SVN changeset easily, here are the documentation and batch-file:

Documentation

Steps to install:
0- Quit Delphi XE4
1- Download the GExperts XE4 experimental from http://blog.dummzeuch.de/2013/04/28/experimental-gexperts-code-formatter-for-delphi-xe4/
2- Recursively unpack that download
3- Copy the batch file Install-GExperts-XE4-experimental–run-as-administrator-from-ExpertManager.exe-directory.bat into that directory
4- From that directory, run the copied Install-GExperts-XE4-experimental–run-as-administrator-from-ExpertManager.exe-directory.bat
5- Run Delphi XE4
6- Check if GExperts is installed

Batch file

:: check if user is administrator

  "C:\Windows\system32\cacls.exe" "C:\Windows\system32\config\system" 1>nul 2>&1  && (goto :isAdmin)
:isNoAdmin
  echo you need to be Administrator, and (when under Vista or higher) run this using using UAC
  goto :exit

:isAdmin

:: Gets the right link for x86 (32-bit) program files
IF /I %PROCESSOR_ARCHITECTURE% == amd64 goto :x64
IF /I %PROCESSOR_ARCHITEW6432% == amd64 goto :x64
goto :x86
:x64
   :: OS is 64bit
   set ProgramFilesX86=%ProgramFiles(x86)%
  goto :continue
:x86
   :: OS is 32bit
  set ProgramFilesX86=%ProgramFiles%
  goto :continue

:continue

:: create the right directory and copy the files

  setlocal

  set TargetDirectory=%ProgramFilesX86%\GExperts for RAD Studio XE4

  mkdir "%TargetDirectory%"
::  set FilesToCopy=DbugIntf.pas ExpertManager.exe GExperts.chm GExpertsDebugWindow.exe GExpertsGrep.exe regularexpert\GExpertsRSXE4.dll Readme.txt preview.pas
  set FilesToCopy=ExpertManager.exe GExperts.chm regularexpert\GExpertsRSXE4.dll preview.pas

  for %%f in (%FilesToCopy%) do copy /y %%f "%TargetDirectory%\"
  set RegFile="%TargetDirectory%\ExpertsXE4.reg"
::  explorer /select,"%TargetDirectory%\GExpertsRSXE4.dll"

:: expand backslash into double backslash for .REG file
  set ExpertTarget="%TargetDirectory%\GExpertsRSXE4.dll"
  set ExpertTarget=%ExpertTarget:\=\\%

::Windows Registry Editor Version 5.00
::
::[HKEY_CURRENT_USER\Software\Embarcadero\BDS\11.0\Experts]
::"GExperts"="C:\\Program Files (x86)\\GExperts for RAD Studio XE4\\GExpertsRSXE4.dll"
::
  echo Windows Registry Editor Version 5.00 >%RegFile%
  echo. >>%RegFile%
  echo [HKEY_CURRENT_USER\Software\Embarcadero\BDS\11.0\Experts] >>%RegFile%
  echo "GExperts"=%ExpertTarget% >>%RegFile%
  echo. >>%RegFile%
::  explorer /select,%RegFile%
  regedit /S %RegFile%

  endlocal

  goto :exit

:exit

WinAmp AACPlus v2 Encoder: how to encode mono

Posted by jpluimers on 2013/06/05

AACPlus allows for a many combinations of encoding flags.

Finding out whick allows to encode a mono audio stream is a bit time consuming.

Luckily, I found this post:

If you want encode in mono make this:

enc_aacPlus test.wav test.aac --br (max 256000) --mono

or for streaming:

enc_aacplus - - --br (max 256000) --silent --rawpcm 44100 2 16 --mono

Note that the various versions of enc_aacPlus.exe requires the enc_aacPlus.dll from WinAmp.

Mac OS X: editing ~/.bash_profile using TextEdit

Posted by jpluimers on 2013/05/10

Finder on your Mac by default does not show hidden files, and the console has vi, which lots of people find awkward to use.

There is an easy trick to open a hidden file like ~/.bash_profile (for instance to add an alias) with a visual text editor.

Just execute this in your terminal:

  • Always with TextEdit
    open -e ~/.bash_profile
  • For the default text editor (usually TextEdit)
    open -t ~/.bash_profile
  • For a specific text editor (in this cast TextWrangler)
    open -b com.barebones.textwrangler ~/.bash_profile

The man open(1) page has more information on the parameters you can pass to open.
