mc (mc over ssh on a putty console)
- to reproduce try this:
1) run 'putty'; login to remote host
2) run mc
3) press key '/' on keypad. You will see menu that is called when you press the F2
4) Go to 'Learn keys' (simple call dialog)
5) just exit from 'learn keys' dialog (without any changes)
6) 3) press key '/' on keypad again. You will see '/' symbol in command line.
experimental patch, completely different reading file, new cache structure,
shall view text in every encodings (remaped ctrl + t, new dialog need
localization).
1. to avoid backward reading, viewer keeps four following characters from
file: next, actual and two previous. This is enough to handle new lines
and nroff fortmatin correctly.
2. cache_line structure, that presents one line in file. cache_line stores,
where line starts and ends in file,number of line and width of line. Width
is at most equal to screen width, so longer lines are cached in more
cache_lines. This makes wrapping text very easy. Cache_lines are stored
in a linked list. file is loaded into cache_lines sequential, not whole at once.
It only provides navigation in file.
I found two problems in this solution:
1. slow first move to end in large files, because can not read files
backward. (loading in background may help)
2. it is slow with multibyte characters. I tried to eliminate calling iconv
to two, but it did not help (iconv is called on every byte). I think
caching some parts of file will be needed.
add support for filesystem, that use others encodings than mc (vfs). Now can be
encoding set only manually, but automatic detection is possible. Filename is
converted in mc_readdir and other function translate it back by vfs_translate
added menu etries encodnig in left and rigth menu (localization will be neede)
modified subshell.c to put subshell correct working directoy,
modified ext.c and execute.c to translate filename before running command
there could be one problem, vfs_translate_path does not use something like
path_magic function
rest of fixes in files cmc.c, main.c (xterm title), panelize.c, subshell.c,
tree.c, tty.c, user.c, util.c, win.c
now, basic mc's function should work well, editor and view are still broken.
like buttons use menu entries hotkey_t. But menus are staticly defined, so this
change is much bigger. All menu declaration must be edited. follow standard
changes in drawing and handling hotkeys.
now basic mc's functions works in utf-8, remain correct calculation of controls
width in dialogs, replace functions like tolower, toupper,isspace, ... width
functions from strutil or g_ascii variant.
like in input, added multibytes characters buffer for search in panel (ctrl+s)
drawing is simplier, because alignment do directly str_fit_to_term function
from strutil, changed time functions in util to work correctly in utf-8

changes in sorting strings (name, extension), for comparing are created keys
from strings and than their are compared instead of primary strings. (in
reality, keys are created only for case insensitive comparing, case
sensitive compare original strings). In utf-8 shall by keys faster than
compare strings directly. But this need ediding declaration of all sorts
functions.
