Initial development with fake directory tree is done

Next:

• replace fake tree with real tree generated from cwd
• watch for directory changes in order to refresh internal structure

or (much better)

• generate plain lists of files and directories dynamically when accessing a new directory (either with cd or with tab completion) instead of managing a tree structure

[pfraces]

Simulate a chroot from the real cwd (directory from which editor is called), so when cd is typed it redirects to that directory and cd .. on root redirects to root

[pfraces]

Make . and .. an implementation detail (hack on Josh path completion handler)

• getChildNodes must return them
• getNode must normalize its path

Normalization

• relative path tokens (., ..) require path starting on root
• remove double slashes: s;/+;/;g
• remove relative tokens from the start to prevent chroot leaks: s;^/([.]+/)+;/;
• remove all previous .. relative tokens and its parents: s;[^./]+/[.][.]/;;g (this must be runned as long as matches are found

But normalization is maybe a responsability of fs.readfile or fs.readdir. Isn't it? BTW fs implements a normalization path algorithm we can use and forget about its implementation

[pfraces]

real cwd

All paths must be relative to chroot, in order to use the fs methods with absolute paths (chroot + relative)
