PATCHING

This page describes how to patch a MicroEmacs installation with a later release without re-installing.

Windows

Windows requires careful patching in order not to disturb the registry settings The following procedure should be followed.

• Move to the jasspa directory, c:\ProgramFiles\JASSPA\Microemacs.
• COPY the executable me32.exe to a backup, you MUST copy the file otherwise the registry settings will change. DO NOT MOVE THE FILE.

  copy me32.exe me32_2002_12.exe 
  

  Save the macros directory, these may be moved i.e.

  rename macros macros_2002_12 
  

  Unpack and install the new Windows executable and COPY over the original executable that was previously backed up i.e.

  copy c:\path-to-executable\me32-win32-20040108-rc1.exe me32.exe 
  

  Create a new macros directory and install the macros into this new directory, do this manually or using a utility like WINZip.

  mkdir macros 
  cd macros 
  unzip c:\path-to\memacros-20040108-rc1.zip 
  

  The new version of MicroEmacs will now operate with the old installation environment. You may return to the old release by reversing the steps to patch the installation.

UNIX/Linux

For *NIX package installations then patching is a little easier. The steps are defined as follows:-

• Move to the jasspa directory.

  cd /opt/jasspa/bin 
  

  Save the original executable.

  mv me me_200212 
  

  Unpack the new executable and make it executable.

  gunzip me-sun-solaris-20040108-rc1.gz 
  mv me-sun-solaris-20040108-rc1 me 
  chmod a+x me 
  

  Save the existing macros directory.

  cd /opt/jasspa 
  mv macros macros_200212 
  

  Create a new macros directory and install the new macros:-

  mkdir macros 
  cd macros 
  unzip /path-to/memacros-20040108-rc1.zip 
  

  Installed packages are built with the install path built into the executable, this may be different from the patch version of the executable so the environment variable $MEINSTALLPATH(5) may be defined in the environment with the macro installation search paths.
