JSDoc: Lookup tutorials from different directories - jsdoc

Question

Is there a way to ask JSDoc (either in the command line or through grunt-jsdoc plugin) to lookup tutorials from different directories ?
As per the documentation, -u allows to specify the Directory in which JSDoc should search for tutorials. (it says the Directory instead of Directories).
I tried the following with no luck:
specify different strings separated by space or comma
specify one string with shell/ant regular expression

As suggested by #Vasil Vanchuk, a solution would be creating links to all tutorial files within a single directory. As such, JSDoc3 will be happy and it will proceed with the generation of all tutorials.
Creating/maintaining links manually would be a tedious task. Hence, and for people using grunt, the grunt-contrib-symlink come in handy. Using this plugin, the solution is reduced to a config task.
My Gruntfile.js looks like the following:
clean:['tmp', 'doc'],
symlink: {
options: {
overwrite: false,
},
tutorials: {
files: [{
cwd: '../module1/src/main/js/tut',
dest: 'tmp/tutorial-generation-workspace',
expand: true,
src: ['*'],
}, {
cwd: '../module2/src/main/js/tut',
dest: 'tmp/tutorial-generation-workspace',
expand: true,
src: ['*'],
}]
}
},
jsdoc: {
all: {
src: [
'../module1/src/main/js/**/*.js',
'../module2/src/main/js/**/*.js',
'./README.md',
],
options: {
destination: 'doc',
tutorials: 'tmp/tutorial-generation-workspace',
configure : "jsdocconf.json",
template: 'node_modules/grunt-jsdoc/node_modules/ink-docstrap/template',
},
}
},
grunt.loadNpmTasks('grunt-contrib-symlink');
grunt.loadNpmTasks('grunt-jsdoc');
grunt.registerTask('build', ['clean', 'symlink', 'jsdoc']);
grunt.registerTask('default', ['build']);
Integrating new module is translated by updating symlink and jsdoc tasks.

You could just copy the files instead of linking to a bunch of directories.
E.g. create a dir in your project for documentation in which you'll copy over all relevant tutorials from where ever.
Then, in your npm scripts you can have something like this:
"copy:curry": "cp node_modules/#justinc/jsdocs/tutorials/curry.md doc/tutorials",
"predocs": "npm run copy:curry",
The docs script (not shown) runs jsdoc. predocs runs automatically before docs and, in this case copies over a tutorial in one of my packages over to doc/tutorials. You can then pass doc/tutorials as the single directory housing all your tutorials.
In predocs you can keep adding things to copy with bash's && - or if that's not available for whatever reason, you'll find npm packages which let you do this (therefore not relying on whatever shell you're using).
Now that I think about it, it's best to also delete doc/tutorials in predocs:
"predocs": "rm -rf doc/tutorials && mkdir -p doc/tutorials && npm run copy:tutorials",
That way any tutorials you once copied there (but are now not interested in) will be cleared each time you generate the docs.
btw, I opened an issue for this: https://github.com/jsdoc3/jsdoc/issues/1330
