osx - Why does Ruby's ri not return to a bash command prompt? -

-

when execute ri ... in terminal on mac, get, maybe, 50 blank lines, output i'm expecting, last line:

(end)

, (end) displayed white letters on black background. not returned bash, -- ri still running, , can't enter anything. also, why blank lines?

why happening?

the output being piped through pager (the value of environment variable $pager, /usr/bin/more or /usr/bin/less). allows page through screenfuls of data hitting spacebar (among other nice features), instead of having scroll , down in terminal. exit, type q.

is necessary this: /** * ... * * @return void */ i have quite few methods don't have return value, , seems redundant put in comment. considered bad form leave out? if makes clear documentation, leave in, isn't strictly necessary. it's entirely subjective decision. personally, leave out. edit stand corrected. after little googling, wikipedia page says: @return [type description] tag should not used constructors or methods defined void return type. the phpdoc.org website says: @return datatype description @return datatype1|datatype2 description the @return tag used document return value of functions or methods. @returns alias @return support tag formats of other automatic documentors the datatype should valid php type (int, string, bool, etc), class name type of object returned, or "mixed". if want explicitly show multiple possible return types, list them pipe-delimited without spaces (e.g. "@retur...
