You can think about it as simplifying of the first argument "cd" command (a standart bash command). Simplifying means making shorter.
For instance if I do
it works the same as
. Which means "b" is simplifying of "a/../b". It is much easier to explain everything using examples.
Input: String. Non-Empty valid unix path.
Output: String. Unix path.
# last slash is not important simplify_path('/a/') == '/a' # double slash can be united in one simplify_path('/a//b/c') == '/a/b/c' # double dot - go to previous folder simplify_path('dir/fol/../no') == 'dir/no' simplify_path('dir/fol/../../no') == 'no' # one dot means current dir simplify_path('/a/b/./ci') == '/a/b/ci' simplify_path('vi/..') == '.' simplify_path('./.') == '.' # you can't go deeper than root folder simplify_path('/for/../..') == '/' simplify_path('/for/../../no/..') == '/' # not all double-dots can be simplyfied in related path simplify_path('for/../..') == '..' simplify_path('../foo') == '../foo'

Sync solutions into your local folder
(in beta testing) Launch local server so your browser can use it and sync solution between local file end extension on the fly. (doesn't work for safari)
checkio serv -d
Alternatevly, you can install Chrome extension or FF addon
