Christoph Lohmann b16b5d77d3 Fixing a off-by-one error in the new border clearing code. 2012-10-06 20:52:22 +02:00
Roberto E. Vargas Caballero 2bd0c23fa7 Print control codes only in graphic mode
Non handled codes must be ignored, except in graphic mode. Also STR
sequences have higher priority than control codes, so they must be handled
before of them.

Roberto E. Vargas Caballero 034dc71fb8 Add SI and SO control codes
SI and SO allows change the G0 and G1 selection. This implementation is not
full vt100 compatible, but it is complatible with linux virtual terminal
implementation. For full vt100 compatibility we need remake a lot of stuff
relate to the different charmaps.

Roberto E. Vargas Caballero ac8f05c45a Add documentation to control codes
Add the documentation from the vt100 manual programmer:

Control 	Octal      Action Taken
Character	Code
-------------------------------------------
NUL		000	Ignored on input (not stored in input buffer;
			see full duplex protocol).
ENQ		005	Transmit answerback message.
BEL		007	Sound bell tone from keyboard.
BS		010	Move the cursor to the left one character position,
			unless it is at the left margin,
			in which case no action occurs.
HT		011	Move the cursor to the next tab stop,
			or to the right margin if no further tab stops
			are present on the line.
LF		012	This code causes a line feed or
			a new line operation. (See new line mode).
VT		013	Interpreted as LF.
FF		014	Interpreted as LF.
CR		015	Move cursor to the left margin on the current line.
SO		016	Invoke G1 character set, as designated by SCS
			control sequence.
SI		017	Select G0 character set, as selected by ESC ( sequence.
XON		021	Causes terminal to resume transmission.
XOFF		023	Causes terminal to stop transmitted all codes
			except XOFF and XON.
CAN		030	If sent during a control sequence, the sequence is
			immediately terminated and not executed. It also causes
			the error character to be displayed.
SUB		032	Interpreted as CAN.
ESC		033	Invokes a control sequence.
DEL		177	Ignored on input (not stored in input buffer).

Christoph Lohmann 0cc7ee5e73 Removing the xclearborders() hack. St now cleans up the parts of the border,
if something needs to be drawn close to it.

Christoph Lohmann 7efa4514d1 Adding the patch of David Dufberg Töttrup to implement WM_DELETE_WINDOW. Thank you! 2012-10-05 22:59:08 +02:00
Christoph Lohmann bf6cf05ba5 Fixing the brightening on bold. For the 256 colors and greyscale I assumed a
reasonable solution.
2012-10-05 22:51:08 +02:00
Christoph Lohmann 5caa46cf57 Turning on antialias by default really makes it more unreadable. Maybe if once
the majority has bigger screens, this can be turned on by default again.
Thanks pancake, for the hint.

Christoph Lohmann 0b489c4a6a When the drawing behaviour was changed underline was not corrected.
Thanks to Peter A. Shevtsov!

Christoph Lohmann 2752018e27 This adds the fontcache dependency to try something out. Additionally the
invert mode now works as expected. In the config.def.h autohint is set to
false, so the fonts are drawn correctly, without any overlapping.
2012-10-04 22:59:45 +02:00
Christoph Lohmann 0d88f1ef75 Thanks to c00kiemon5ter. Not changing bold to bright colors seems to be the
right choice.

Christoph Lohmann af9e248f97 Removing the now obsolete definitions from the config.def.h file. 2012-09-30 20:23:45 +02:00
Christoph Lohmann 5dfd5df4fe This changes -f to be the parameter for the font. Now -f is -o.
The parameters were reordered according to the alphabet too.

Christoph Lohmann 9cae1eb0de Remove the cruft of the user to have to define the different font styles. 2012-09-30 20:10:58 +02:00
Christoph Lohmann ed5b8700a6 We need all the colors to be available, so die() on some not available.
This is a new opportunity to see if X11 somewhen handled colors in a strange
way.
2012-09-29 11:23:34 +02:00
Christoph Lohmann d7b1e31eec All xcolors are not Xft colors and the clearing of the borders has been
optimized. There is a speedup when resizing windows.

Christoph Lohmann 29b209f5f5 Vt escape sequences allow escape sequences in escape sequences and escape
sequences, so we have to support escape sequences in escape sequences that
escape sequences in escape sequences – setting a title won't notify you

Roberto E. Vargas Caballero 3af49e34f6 Allow control characters inside escape sequences
Taken from vt100 manual programmer:

	Control characters (codes \0 to \37 inclusive) are specifically
	excluded from the control sequence syntax, but may be embedded
	within a control sequence. Embedded control characters are executed
	as soon as they are encountered by the VT100. The processing of the
	control sequence then continues with the next character received.

Roberto E. Vargas Caballero a7d7e29300 Ignore all control characters not handled
Taken from vt100 programmer manual:

	Control characters have values of \000 - \037, and \177. The control
	characters recognized by the VT100 are shown in Table 3-10. All
	other control codes cause no action to be taken.

We have to take attention when we are using alternate charset, because in
this cases they are not used as control characters.

Roberto E. Vargas Caballero eb360e5fd1 Fix bug in tputc writing to io file
If -f options is enabled then tputc() writes all the data to a file. Actual
code assumes that all the strings in 'c' parameters have always 1 byte
length, but this is not always true, because due to utf-8 encoding some
characters can have a diferent length. So it is necessary pass string length
to tputc in order it can call to write() correctly.

Christoph Lohmann 246d704ba0 Changing the default font to DejaVu Sans Mono, which is more appealing and
activating antialiasing.
2012-09-24 14:01:59 +02:00
Christoph Lohmann 055a4f6d2c The xinit() call needs to be behind all the tty init, otherwise all the
allocated structures are wrong. The xclear() is now done on purpose. Please
keep X11 calls out of the way of pure tty-related calls.

Roberto E. Vargas Caballero 74d6abfee5 Add some documentetion to tsetmode
The names of the terminal modes supported by vt102 are (taken from the VT220
programmer reference manual):

Roberto E. Vargas Caballero b6cfff1625 Clear X window in tsetreset()
tsetreset() is called when it is necessary a full initialization of the
terminal, so it also should clean the full X window and not only the
terminal content. It is necessary change the order of the
initialization in main(), and put xinit before of tnew(), because tnew()
calls to tsetreset(), and  this can cause a call to xreset() with
incorrect values.

Christoph Lohmann e4bf2679c1 Fixing the redrawing patch of k0ga, so it's using xclear() in redraw() too. 2012-09-17 22:44:27 +02:00
Roberto E. Vargas Caballero 4876d6e05b Clean windows display after resizing
Some times the size after a resizing is not an exact multiply of a number of
characters, so redrawn the screen using the lines and columns of the neww
size can cause that some old graphics keep in the screen. Solution is clean
all the windows with the background color.

Roberto E. Vargas Caballero 88a8f85a8a Copy non set positions as spaces
st selection don't insert in the selection position whose value is not
set. This is correct for the positions in the end of the line, but cause
some problems in the beginning. For example echo -e 'a\tb' will print in the
screen:

a	b

but after selecting and copying in some place you get:

ab

because positions from 1 to 7 don't have any value. This patch deals all
positions without value as blank (even at the end of the line).
