Adding a pathdef.m file, as a string, to the current path

3 views (last 30 days)
I have saved a pathdef file ('pathdef_etc.m') which contains the paths that I need for a given project. I simply want to get the string output from this pathdef file, so that I can add it to my current path using 'addpath( path_string )'.
How can I get this pathdef file as a string?
Thank you

I am looking for something like...
*from the directory containing the pathdef file*
so that I can type addpath(ans)

What is the file format? Did you create it with savepath ?
Are the individual paths separated by colon or by newlines?
Is this for Windows or (not Windows) ?

You probably want to use textscan for this:
fileID = fopen('pathdef_etc.m')
C = textscan(fileID, '%s', 'Delimiter', '\n')
The output is a single cell containing a n-by-1 cell array of character vectors (one per line in the input file). So C{1}{1} contains the first line of your file, C{1}{2} the second, and so on. You could then set up a loop to add each line to the path:
for i=1:size(C{1},1)
Hope this helps!

I just figured it out actually. It was really simple. I just needed to find the pathdef file in the explorer, right click -> 'run',
then the path appeared in command window as one really long string.. 'ans = path1, path2, etc .... '
then just addpath(ans).
Thank you for your help though.
