An absolute path is necesary because the current working directory
changes for each example. To check this I added,
import sys
sys.stderr.write('SAMPLE cwd=%s\n'%os.getcwd())
sys.stderr.write('SAMPLE matplotlibrc=%s\n'%matplotlib.matplotlib_fname())
to the beginning of cbook.get_sample_data(). During the documentation
build I then saw output like,
reading sources... [ 12%] examples/api/date_demo
SAMPLE cwd=/home/bgamari/trees/matplotlib/matplotlib-1.0.1/examples/api
SAMPLE matplotlibrc=/home/bgamari/.matplotlib/matplotlibrc
reading sources... [ 12%] examples/api/date_index_formatter
SAMPLE cwd=/home/bgamari/trees/matplotlib/matplotlib-1.0.1/examples/api
SAMPLE matplotlibrc=/home/bgamari/.matplotlib/matplotlibrc
I suppose the only way around this is to patch the absolute path into
doc/matplotlibrc with sed, and then invoke doc/make.py with
MATPLOTLIBRC="$(CURDIR)/doc/matplotlibrc". I'm very confused how you
found that specifying a relative path in download.path worked. If the
cwd changes as seen above then the documentation was entirely correct in
claiming an absolute path is necessary. I really do wish there as a way
to prevent spinx from changing the cwd.
