Fixing the brightening on bold. For the 256 colors and greyscale I assumed a

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.

When the drawing behaviour was changed underline was not corrected.

Thanks to Peter A. Shevtsov!

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.

Thanks to c00kiemon5ter. Not changing bold to bright colors seems to be the

right choice.

Removing the now obsolete definitions from the config.def.h file.

This changes -f to be the parameter for the font. Now -f is -o.

The parameters were reordered according to the alphabet too.

Remove the cruft of the user to have to define the different font styles.

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.

All xcolors are not Xft colors and the clearing of the borders has been

optimized. There is a speedup when resizing windows.

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
anymore.

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.

	Control characters have values of \000 - \037, and \177. The control

	other control codes cause no action to be taken.

We have to take attention when we are using alternate charset, because in

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.

Clear X window in tsetreset()

tsetreset() is called when it is necessary a full initialization of the

Clean windows display after resizing

Copy non set positions as spaces

st selection don't insert in the selection position whose value is not

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

Fix selection bug

After the commit named "Remove timeout in the main loop", selection is not

Render only once in each main loop iteration

draw() runs over all lines of the screen and renders only the dirty lines,
this avoids render lines which are not modified since last draw() call. In
this moment the main loop is something like:

     - Wait something to read from file descriptors
     - Read from pseudo tty
     - Call draw() for rending
     - Read X events

This cause the problem that all the X events that have to update the screen
have to call draw() (because draw() is called before of X events handling),
so you can have multiples renderings in only one iteration, that will waste
a lot of resources.

This patch change the main loop to:

     - Wait something to read from file descriptors
     - Read from pseudo tty
     - Read X events
     - Call draw() for rending

So X events don't have to worry about rendering, because draw() is called
after them.

The only place where draw is called outside of the main loop is in redraw(),
but it is necessary for getting a good tput flash.

Remove timeout in the main loop

The main loop waits until there is some data to read in file descriptors of

patch removes this problem removing the timeout, which is not needed.

Remove buffering to fileio instead of calling fflush

By default text files are line buffered, and this means that -f option will

Add xmalloc and xrealloc wrappers

If malloc  or realloc fail they return NULL. Theorically this condition
should be tested in the code, but it's a strange condition today (basically
if this is hapenning thenyou have a big problem), and even Linux never returns
NULL in the default configuration (only if the process don't have room in
the space address, something a bit impossible in the case of st). But stis
enough small for being executed in low resources computers where this can be
a real problem. So the easy way is creating a wrappers function for them and
call to die in case of error.

st marks the active selection using reverse colors in the box selection, but

emulators remove the highlight when it is not valid anymore.

X sends a SelectionClear event in this situation, so we only have to add a
callback which unhighlight the selectin box.

Check alternative screen before drawing box selection

Some programs use the alternative screen (vi, less, ...), whose
content is different of the main screen. If you select text in one of
the screen, you don't wait the box selection is painted in the other
screen, so it is necessary check if the selection was done in the same
screen we are going to paint. Before to this commit, you could do
something like:

	$ LESS="" ls | less
	(select some code)
	q

and selection box remains drawing in the main screen, but the content
of selection keeps text of the alternate screen.

Patch from Roberto Vargas. »Add initialization strings in terminfo«


Taken from the description:

When tput init is executed the list of task performed are (taken from
terminfo(5)):

              run the program
                     iprog

              output is1 is2

              set the margins using
                     mgc, smgl and smgr

              set tabs using
                     tbc and hts

              print the file
                     if

              and finally
                     output is3.

When reset is executed, a more stronger initialization process is performed,
so the terminal can return from an unknown state. rs1, rs2 and rs3 are used
in this case instead of
using is1, is2 and is3.

This patch makes is2 = rs2, resets insert mode and set normal keypad
mode. For rs1 it performs a full initilization using ^[c.

Add standout mode.

Cleaning up lonely tabs.

Make it more obvious where the wrong attribute is used.

Enable multiple arguments in SM and RM

SM and RM can receive multiple parameters, but the code only was accepting
only one. This patch join the code of set and reset modes (SM and RM) in a
common function and uses a loop which deals with all the arguments of the
sequence. This patch improves xterm and vt100 compability.

added PBaseSize hint and set default title to "st".

rearranged code, resize fixed.

little clean up.

use SHELL environment variable (thx Thomas Adam)

double-buffering added using pixmap (finally).

results in a lot of simplification :
	- no more dirty flags (perf are good enough).
	- no more ugly gfx call in emulation functions.
LINESPACE removed from config.h.
BORDER is now handled correctly.

bold attribute is back.

visibility of the cursor is not saved/loaded anymore.
scrolling up/down is fixed.
added RI and RIS sequences.
fixed cursor drawing bug.

added VT100 NEL.

added VT100 RI.

added VT100 save&load cursor support.

ECH handled correctly.

more escapes & more compability:

cursor keys are handled in kpress according to the Application Mode (DECPAM).
define & enum were renamed.
tcursor() is now tmovecursor() which is more correct.
tcpos() is now tcursor(), as DECSC is also supposed to save attributes.
capnames are indicated whenever possible.

Currently:
alsamixer looks fine, totally usable.
ncmpc is almost ok.
emacs looks like shit.

graphic charset and a few more escapes.

TERM set to xterm by default (which broke a lot of stuff), better escape handling (title), and a little clean up.

drawing is faster but the bold attr is not supported anymore.

Fixed possible segfault by reverting to the key struct (again).

only compile tdump if DEBUG flag is set

we definately need pixmaps for the drawing, currently drawing into the window is painfully slow! much more slower than drawing into a pixmap and mapping that when finished -- several optimisations

updated "key" to a lookup table.

removed old unused cursor() proto.

fixed the scrolling bug and cleaned some stuff.

dump escseq if not handled.

clean up.

Removed unused variable and cleaned some comment.

backport of local changes

add accidentally omitted word

use stdio(3)

add description of std

add prototype for command parsing

correct year of copyright notice

simplify Makefile


Due to consideration of POSIX compliance issues config.mk had
to be removed. Configuration variables can be overridden by
environment variables or specified via command line.

Additionally all pretty-printed messages were removed and
built-in rules are used. This also simplifies and purges
the Makefile.

reunite pty.c with std.c

correct programme name

use errx() for help and version messages

merge with backout head

remove TODO

make ptm and pts static

remove useless variable

remove emallocz()

replace eprint() functions with BSD error functions

simplify flushing

correct buffering

make local functions and variables static

add select(2)-based i/o multiplexing

drop stdio usage


Std requires I/O multiplexing which is very complicated with
stdio, because it provides no transparent buffering.

make st and std separate programmes

add missing header file

assume glibc by default

source utility functions out to util.c

add copyright comment

source getpty() out to pty.c

update TODO

correct function name

remove xinerama flags


The xinerama related variables in config.mk are a relict of
dwm and therefore should be removed.

add missing header file

add parser loop

remove useless variable

replace state with separate variables

terminate error message with newline

correct LENGTH()

simplify control flow

remove debug code

remove stdio slave pty opening

drop support for proprietary UNIX variants


Proprietary UNIX variants like AIX, HP-UX or SCO UNIX
are nowadays rarely used and maintaining compatibility to
non-standard operating systems interfaces is wasteful and
practically useless.

Projects like xterm suffer from backward compatibility to decades-old
UNIX variants and terminal standards. This does not conform to st's
design goals.

slight changes

applied Matthias-Christians changes to std.c

added some new files for the initial rewrite of st from scratch

added new TODO

Backed out changeset d2bb4220fdf3


Ptm and pts are used by pty.c, thus they have to be non-static.

fix warning

Fix unused variable issue and OSX includes

change "op" cap in terminfo entry to xterm/rxvt value.

fix custom key handling.

drawregion() only copies region on screen.

some minor fixes

use typedef'd unsigned type and regular bool type.
