* move file helper functions to separate fileSascha Hauer2014-08-071-0/+1
| | | | | | | | | | We have our file helper functions in several places. Move them all to lib/libfile.c. With this we no longer have file helpers in fs/fs.c which contains the core fs functions and no functions in lib/libbb.c which are not from busybox.

* add menutree commandSascha Hauer2014-03-281-0/+181
Creating menus from the shell using the regular 'menu' command is rather complicated. This adds a 'menutree' command which creates a menu from a directory structure. In the directory structure each directory corresponds to a single menu entry. The directory contains the following files: title - A file containing the title of the entry as shown in the menu box - If present, the entry is a 'bool' entry. The file contains a variable name from which the current state of the bool is taken from and saved to. action - if present this file contains a shell script which is executed when when the entry is selected. If neither 'box' or 'action' are present this entry is considered a submenu containing more entries. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
