-in option to search from file

[rodrigoalvesvieira]

We must implement in the Options class the option from searching projects from the content of an informed file so that the names of the project can be passed in "bulk" rather than individually. Take this as an example:

Currently we do:

java -jar groundhog.jar -forge github -out metrics phonegap-facebook-plugin facebook-android-sdk spring-social-facebook

This will look for projects whose name match either phonegap-facebook-plugin, or facebook-android-sdk or spring-social-facebook.

But this approach can be tedious and hard to repeat as the number of projects gets larger.

So, the -in option would make our lives easier by making Groundhog read the search terms from a JSON file, like this:

this file is called projects.txt

phonegap-facebook-plugin
facebook-android-sdk
spring-social-facebook

and then:

java -jar groundhog.jar -forge github -out metrics -in projects.txt

It is an interesting feature, but, IMHO, we should first fix #9 before start this one.

[rodrigoalvesvieira]

Yes, agreed. I guess we should discuss the migration to JCommander ASAP. Will talk to @fernandocastor this week and see.

Development/debugging pro-tip for the SearchGitHub class:

log the searchUrl variable in the getProjects() method, then you can more easily grab an API url and see the content for yourself, if needed. Example (search term: github api): https://api.github.com/legacy/repos/search/github+api?start_page=1&language=java

another example (search term: cepfacil): https://api.github.com/legacy/repos/search/cepfacil?start_page=1&language=java

And if we parse regular expressions in the project name?

Such as java -jar groundhog ... facebook* twitter*

[rodrigoalvesvieira]

hmm, I don't understand :(

[gustavopinto]

I mean, and if the user want to download all facebook related projects. Wouldn't it be nice if I could pass facebook* as parameter and then it download all projects that name starts with facebook?

[rodrigoalvesvieira]

Ah, yeah. Got it.

Using regular expressions to search for projects is also related to issue #19 because you could search for all projects in a repository using the regular expression '*'.

People, I believe that it would be better if the JSON file provided all the command line arguments instead of passing only the names of the projects. @fernandocastor talked about this feature in #17, so I propose that we close this issue, that talks about passing project names through a file, and create another issue about passing all command line arguments. What do you think?

[fernandocastor]

Agreed.

[dnr2]

As I said this issue will be replaced by #33 so I'm closing this one.
