Details:
Using `addpath(pwd)` to add the current working directory to the path removes
'.' from the path. If you then change directories and run a `.m` file, Octave
tells you that the file is undefined.
The following is a minimum working example to show the removal of '.' from the
path and, further down, that Octave no longer finds a file that is in the
current directory.
% Show that addpath(pwd) removes '.' from path
find(strcmp(strsplit(path,":"),'.'))
addpath(pwd)
find(strcmp(strsplit(path,":"),'.'))
% Create tmp/file_to_run.m
mkdir tmp;
cd tmp;
fname = 'file_to_run';
fid = fopen([fname '.m'],'w');
fprintf(fid, 'a=1');
fclose(fid);
% Show that Octave no longer finds file_to_run.m because '.' is not in the
path
pwd
ls([fname '.m'])
evalin('base', fname)
NB: I am using Octave 4.2.0-rc2 on OS X 10.12 installed through Homebrew, but
I get the same bug on Octave 4.2.0-rc2 that I built myself on Debian Jessie.
