Details:
textscan under octave 4.2.1 produces a garbled cell array from a text file
input but under Octave 4.02 the output is as one
would it expect it to be.
A commented text file(configuration file) with variables and assigned values
is read. The delimiter is "=" with "#" read as a comment.
the file 'cruise_params.cfg.tmp'
is first opened and then read with textscan.
The contents are then placed in a cell array.
All works fine under Octave 4.02 but under octave 4.2.1 the cell array is
garbled.
I've included the input file "cruise_params.cfg.tmp" for testing and I've
included a text file(octaveComparison.txt) with the results from the textscan
for each octave version.
Below is a snippet of the output.
Octave 4.02 (correct)
============
fid=fopen('cruise_params.cfg.tmp','r');
cruiseVars=textscan(fid,'%s%s','Delimiter','=','CommentStyle','#');
cruiseVars
cruiseVars =
{
[1,1] =
{
[1,1] = working_directory
[2,1] = cruise_id
[3,1] = cruise_id_prefix
[4,1] = cruise_id_suffix
Octave 4.21 (incorrect)
===========
fid=fopen('cruise_params.cfg.tmp','r');
cruiseVars=textscan(fid,'%s%s','Delimiter','=','CommentStyle','#');
cruiseVars
cruiseVars =
{
[1,1] =
{
[1,1] = working_directory
[2,1] = cruise_id
[3,1] = cruise_id_prefix
[4,1] = correct_year
I'm not sure if it's a problem with textscan or one of its underlying
functions.
This is part of a processing script that runs fine under octave 4.02
