1. Remove unused assert() around io.open of the input device. The failure
to open input device is already guarded by the "if inputf" code.
2. Remove unneeded assert() around io.open of the output device. This is
unneeded because we should not crash the whole application just because
we cannot write screen dump (e.g. because filesystem is full, etc) ---
rather we should exit gracefully.
Instead of calling lfs.mkdir() to create "./history" and "./screenshots"
at runtime it is easier to create them at package build time.
I hesitated whether to add "./clipboard" to this list but decided
against it as we can perhaps change current directory and then
all the code manipulating clipboard would break, so I left it as is.
- zip files don't require double extensions any more
- filechooser has 'H' shortcut to display keys
- new function for files and folders (^ == shift)
^N - new folder
Del - delete document/folder
^C - copy file into clipboard
^X - cut (move) file to clipboard
^V - paste files from clipboard
^R - rename file
- configurable keyboard for input box
* Since fontchooser is replaced by selectmenu, it
is no longer needed. So I rewrite it into font.lua
module which can cache faces that shared among all
UIs.
* add progressBar method in graphics.lua to draw
reading progress.
* add reading progress information in reading menu.
It is just a demo. Should be clean up in next release
when the real reading menu is out. :)
Now you get a instance rotate :) With only one bug.
I have to restore to previous rotation state of the
native system after exists. Because the native system
does poll the new rotation state that changed by ioctl.
Currently, I don't know how to force the native system
to detect the changes.
