5svnstat uses a C++ interface to Gnuplot written by Rajarshi Guha. The
6interface is integrated in the svnstat code with some modifications
7(see below). The original code used for svnstat can be found in
8directory ./gnuplot_i++.
9
10Rajarshi Guha's "A C++ Interface to Gnuplot" can be found through
11http://jijo.cjb.net/ . The C++ interface is based on "gnuplot
12interfaces in ANSI C" written by Nicolas Devillard. The C implemention
13is available through http://ndevilla.free.fr/ .
14
15Changes made to the C++ Gnuplot interface files (gnuplot_i.hpp and
16gnuplot_i.cc):
17
18i) Changed filename gnuplot_i.hpp to gnuplot_i.h, and consequently
19   changed #include directive in gnuplot_i.cc.
20
21ii) Encapsulated the interface into namespace theplu::svnstat.
22
23iii) Added 'Id' tags in both files.
24
25iv) Changed the initial #ifndef/#define idiom to avoid potential
26   clash with the original implementation.
27
28v) gnuplot_i.h: Removed the 'using namespace std;' statement, since we
29   don't want to expose the std namespace to everyone using the
30   Gnuplot interface. This triggered subsequent changes to code lines
31   with string and vector<> usage.
32
33vi) Resolved signed/unsigned compiler warnings in gnuplot_i.cc on
34   lines 235, 278, 418, and 482
35
36vii) gnuplot_i.cc: Changed order of code in Gnuplot destructor, now
37   the pipe is closed first. I have not done a full scale
38   investigation on why this is needed, but on MacOSX the files are
39   removed before gnuplot plots data when the original code order is
40   kept.
