This article is about MiKTeX packaging: You will learn how to maintain a custom package repository.
A few utilities are required:
cabextract is used intnernally (by MPC) to extract files from cabinet files. It is a part of the Cygwin distribution for Windows.
lzma is used intnernally (by MPC) to
extract files from
.tar.lzma files. It is a part of the
Cygwin distribution for Windows.
MD5Walk is used to calculate the fingerprint of a package. The source code of MD5Walk can be obtained from the MiKTeX project page.
The MiKTeX Package Creator (MPC) is used to maintain the contents of a custom package repository. The source code of MPC can be obtained from the MiKTeX project page.
rsync is used to initialize the custom package repository. It is a part of the Cygwin distribution for Windows.
tar is used internally (by MPC) to create package archive files. It is a part of the Cygwin distribution for Windows.
All but MPC and MD5Walk are standard utilities which are available on all platforms (Windows, Linux, …). The portable source code of mpc and md5walk can be obtained from the MiKTeX project page.
A custom package repository can be initialized with the help of rsync as follows:
rsync -av rsync://www.ctan.org/SYSTEMS/win32/miktex/tm/packages/ .
This will download a snapshot of the remote package repository to
The package staging directory contains all the bits and pieces you will need in order to add a package to the custom package repository.
Basically, the staging directory contains the following:
Description file contains
a mult-line description of the package.
Files sub-directory contains
the actual files of the package.
package.ini file contains
basic information about the package.
Description file and the
Files sub-directory are optional. The
package.ini file is required.
Files directory contains just
texmf, which is the
root of a TDS tree populated with the actual files of the package.
Files could contain
package.ini contains basic
information about the package:
The deployment name of the package. This is the base name of the package archive file.
The fingerprint of the package.
The user friendly name of the package.
The title of the package.
The fingerprint must be calculated with the help of the md5walk utility (see below).
Here is a sample
externalname=mystuff md5=f3fa2edf7bfd8ae692880b59fa246650 name=My stuff title=Provides my style files.
The fingerprint has been calculated as follows:
md5walk --exclude=.tpm Filesf3fa2edf7bfd8ae692880b59fa246650
You use the MPC utility to add a package to your custom package package repository.
Here is a sample invocation:
mpc --create-package --repository=C:\package-repository --verboseLoading database from C:\package-repository... Reading staging directory C:\staging\mystuff... Checking C:\package-repository\mystuff.tar.lzma... Creating mystuff.tar.lzma... Writing database to C:\package-repository...
MPC is run from the staging directory
