FEX submissions are accompanied by a file called "license.txt", which contains the name of the author. You can copy the files of a submission to a specific folder and include if in the Matlab path.
When a user downloads 100 submissions, there are two methods:
Especially when I think about a tool, which automatically resolves dependencies to other FEX submissions, the pile of equivocal license files is a tedious obstacle. How can this problem be solved considering the large number of already existing submissions?
No products are associated with this question.
You could download each FEX submission to a separate folder and then create links (hard or symbolic) to the MATLAB files (m, p, mex, etc.) in a single common folder for all FEX submissions. This might cause problems with name collisions to common files (e.g., contents.m).
I find lots of "installation procedure" enquiries also even though clear install instructions are provided. Often that is because users have read "between-the-lines" instead of taking the instructions literally - and their interpretation can be understandable e.g I see how a 10 year old caveat that "you must use "save -v6" might be interpreted as use "save -v[6 or 7]" in 2013.
For Waterloo, which has many files/folders/classes, I wrote a short script that uses MATLAB to do the download, unzip the files and set up the MATLAB and Java path - providing a few command line prompts/questions - in the present context that might be e.g "Have you run mex -setup before? If not do you want to run it now? [y/N]:"
Maybe the FEX should include an o[tional "Installation Script" button as well as a "Download Button" - providing script code to cut-and-paste into the Command Window when clicked, that could do this.
The license.txt files could be renamed by appending the name of the submission, e.g. "licence.txt" to "license_typecast_.txt" for James' important, efficient and useful helper function FEX: 17476.
A lot of users are overwhelmed by the installation procedures of some submissions. I include a "please compile the code by mex -O abc.c before the first run" in the help section of the code, but I still get more questions for clarifications about the MEX command than comments or ratings. Therefore I hesitate to force the user to download and install another function and compile it in addition.
