The following is a missing piece of documentation for adding new .pyx to the Sage library: See 5.2 of the Sage Programming Guide.

Cython

Writing Optimized Compiled Code with Sage

Examples

Creating .pyx Files in the Sage Library

Suppose you want a more permanent way of including your optimized Cython code in Sage. Perhaps you want to contribute to the Sage project? This guide will show you how to create a simple Cython module and then link it to the Sage library so that your code will appear in future versions of Sage.

Opentick

Opentick provides free real-time and historical market data for trading systems and trading platforms. See www.opentick.com.

This package is used by the sage.finance module.

opentick1.1 (Chris Swierczewski, 27 Aug 2008)

• Checkout from cvs -d :pserver:[email protected]:/var/cvs co otfeed1.1-dev (Note that this currently does not work! Results in following error message:)

  •    cvs [checkout aborted]: connect to cvs.opentick.com(64.210.196.151):2401 failed: No route to host

  For now, download from http://cvs.opentick.com/cgi-bin/cvsweb.cgi/otfeed1.1-dev/otfeed1.1-dev.tar.gz?tarball=1.

• Download patch from http://otfeed-patches.googlecode.com/files/otfeed1.1-dev-autotools.patch into top-level folder so that compiler can use GNU autotools.

• Apply patch using the following command:

  •    $ patch -p1 < otfeed1.1-dev-autotools.patch 
         patching file Applications/HistCsv/Include/Makefile.am 
         patching file Applications/HistCsv/Makefile 
         patching file Applications/HistCsv/Makefile.am 
         patching file Applications/HistCsv/Sources/Makefile.am 
         patching file Applications/Makefile.am 
         patching file AUTHORS 
         patching file ChangeLog 
         patching file configure.ac 
         patching file COPYING 
         patching file Include/Makefile.am 
         patching file INSTALL 
         patching file Makefile.am 
         patching file NEWS 
         patching file OTFeed.CPP/Include/Makefile.am 
         patching file OTFeed.CPP/Makefile 
         patching file OTFeed.CPP/Makefile.am 
         patching file OTFeed.CPP/Sources/Makefile.am 
         patching file README 
         patching file Samples/Linux/Makefile 
         patching file Samples/Linux/Makefile.am 
         patching file Samples/Makefile.am

• Bootstrap the autotool build system:

  •    $ autoreconf -i 
         configure.ac:8: installing `./missing' 
         configure.ac:8: installing `./install-sh' 
         Applications/HistCsv/Sources/Makefile.am: installing `./depcomp'

• Configure, make, and install Opentick source in src/ to $SAGE_ROOT. Libraries are put into $SAGE_LOCAL/lib and headers into $SAGE_LOCAL/include:

  •    ./configure --prefix=$SAGE_LOCAL
       make 
       make install

• Make and install C++ binary, otwrapper. Binary is copied to $SAGE_LOCAL/bin

  •    cd otwrapper
       make
       make install
