2f6647687a tweaks: rename a function, and adjust some comments 2016-08-01 19:41:13 +02:00

c9e9964207 screen: don't look at placewewant but at where we actually were and are 
For horizontal scrolling, it is not the /desired/ column position that
is relevant for determining whether a line needs to be redrawn after a
cursor movement, but the /actual/ column positions before and after.

This fixes https://savannah.gnu.org/bugs/?48627,
and fixes https://savannah.gnu.org/bugs/?48629.

0a3a6441bc tweaks: unconditionally compile a couple of parameters 
Having two unneeded parameters in the tiny version is acceptable --
the code gets so much more readable.

08c51cfd45 input: ingest as verbatim just one control code or one or two escapes 
Leave the rest of any escape sequence to be processed normally, which
should be possible because those characters are all in ASCII range.

This fixes https://savannah.gnu.org/bugs/?48318.

b472f5a633 tweaks: remove some unnecessary keycodes from a switch statement 
These codes are the basic codes that get assigned for the movement keys
in the list of shortcuts -- they don't need any translation.

9cd30d4917 tweaks: don't bother setting meta_key to false when a key is invalid 
That is a task for the key-getting routine.

b9e83fe9f8 tweaks: move some debugging stuff, and move modified editing keys too 
Again, just for preapring an easier return from the parsing routine.

cb10b2b908 tweaks: elide the global variable 'func_key' 
There is no need to specially flag a function key or editing key --
the keycode is indication enough in itself: outside of byte range.

1c528db8da tweaks: condense three asserts into a single one 
Also, when a key string does not denote a Ctrl nor Meta nor Function key,
there is no point in assigning a keycode, because plain characters cannot
be used as a function shortcut.

1c9ab8bf16 tweaks: rename a struct element, to be more fitting 
The keycode is not a sequence; it is a single integer value.

e295070193 shortcuts: group the setting of key string and keycode into one function 
And instead of using two key types, just use a bool to indicate whether
a keystroke involves Meta.

91951ab22a input: don't bother putting a keycode into byte range 
A keycode is either already in byte range (so there is nothing to do)
or it is not and it shouldn't be (so there is nothing to do either).

5b0ab8be62 shortcuts: remove any unnecessary classifying of keys 
After initialization, the type of a key is never used nor needed
(other than for meta keys).

e3dbffc9f7 input: be more strict in recognizing certain escape sequences 
Accept the "Esc [ 1 n ~" and "Esc [ 2 n ~" sequences only when they
end with the "~" character, not with any character.

992533b91e moving: don't do an automatic smart home with Ctrl+Up and Ctrl+Down 
It is nicer to have a predictable cursor position and not see it hop
left and right on differently indented lines.

f3e8991206 credits: don't bother blanking the second line nor the help lines 
Those lines don't exist in that mode -- the relevant subwindows are
smaller, or have been made smaller just before.

c6dbcf91c3 new feature: functions to jump to previous or following block of text 
And hard-bind the keys Ctrl+Up and Ctrl+Down to these functions.

Unlike the paragraph-jumping code, these new functions disregard
any indentation, treating only blank lines as separators.  They
also do an automatic smart home when that option is set.

This fulfills https://savannah.gnu.org/bugs/?48291.
