java - Retrieving location of currently opened file or project in netbeans -


i'm using custom button in netbeans references file in open project. however, i'm having issue retrieving location of file based upon open project. therefore, need can return location of project i'm working in or location of file i'm working with.
in essence, need able call

string projectlocation = methodorvartogetopenprojectlocation();

i can't use current directory, because plugin i've created button doesn't live in same place project i'm working in.

any thoughts?

you can find project directory so:

lookup lookup = utilities.actionsglobalcontext();  project project = lookup.lookup(project.class); fileobject projectdir = project.getprojectdirectory(); string projectlocation = projectdir.getpath();

the classes netbeans api: utilities, lookup, project, , fileobject

if don't want use current project can use openprojects class. can first open project follows:

project project = openprojects.getdefault().getopenprojects()[0];

depending on button might make sense use the main project:

project mainproject = openprojects.getdefault().getmainproject();

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
