Ini file read and write + add new property + matlab -


this question has answer here:

how read , write ini files: want add new property existing one. want write ini file temp file , add new property it. new property have head,name,desc, value , layout (like: line 1 & 3)

#---------------
# head
# --------------
[name]% type
# desc
value

filedata = []; fh = fopen( filename, 'r' ); % read handle tname=tempname(); wfh =fopen(tname,'w'); % write handle line = fgetl(fh); val = ''; prop =''; type = ''; header = ''; desc= '';  while ischar(line)      if strcmpi(line(1),'#') && strcmpi(line(3),'=')         layout = line(2:end);     elseif strcmpi(line(1),'#')&& ~strcmpi(line(3),'=')         header = line(2:end);     else          prop = regexp(line,{'\[*\w+\]\s*%\s*.*\s*'},'match');     [property data_type] = strtok(prop,'%')     prop_p = property{1};% property_name     prop_per  = regexprep(prop_p,{'\[','\]'},'');     prop = prop_per{1};     dtype = data_type{1}; % datatype     dtype = strtrim(strrep(dtype,'%',''));     data_type = dtype{1};  end      % how can define filedname (prop) 'layout' , 'header' found in lines before actual'prop'.    % command window    % undefined variable prop.    % error in ecco2511>add (line 212)   % filedata.(prop{1}).layout = layout;       desc = fgetl(fh); % description     desc = desc(1:end);     line = fgetl(fh);     val = line(1:end);      filedata.(prop).layout = layout;     filedata.(prop).header = header;     filedata.(prop).type = data_type;     filedata.(prop).desc = desc;     filedata.(prop).val = val;      line = fgetl(fh); % keep reading  end  if ~isfield( filedata, propname)     filedata.(propname).val = newval;     filedata.(propname).type = datatype;     filedata.(propname).desc = description;     filedata.(propname).layout = layout;     filedata.(propname).header = header;  else     error ( 'property %s exists, use set change value',propname ); end  filedata = orderfields( filedata ); propnames = fieldnames( filedata );  ii = 1:numel( propnames )      fprintf(wfh,'%s\r',filedata.(propnames{ii}).layout);     fprintf(wfh,'\n');     fprintf(wfh,'%s\r',filedata.(propnames{ii}).header);     fprintf(wfh,'\n');     fprintf(wfh,'%s\r',filedata.(propnames{ii}).layout);     fprintf(wfh,'\n');     fprintf( wfh, '[%s]%s\r', (propnames{ii}),filedata.(propnames{ii}).type);     fprintf(wfh,'\n');     fprintf( wfh,'#%s\r',filedata.(propnames{ii}).desc);     fprintf(wfh,'\n');     fprintf( wfh,'%s\r',filedata.(propnames{ii}).val);     fprintf(wfh,'\n'); end fclose(fh); fclose(wfh); [status,errmsg]= movefile(tname,filename,'f');

sounds need ini config matlab file exchange. allow read, write, , modify ini style files. have used number of times , works quite well.
