Roberto E. Vargas Caballero 288f80cb06 Remove strsep() call
strsep() is not a POSIX function, and it means that every system
needs different defines to expose it. If the prototype of strsep
is not exposed then an ugly int/pointer is done and it might mean
a crash. The best solution?, to remove the strsep and make a custom
loop. If C programmers cannot do this kind of loops without calling
a library function, then maybe we should move all the suckless
software to Java.

Rian Hunter aba6c292af Correct shift amount on MODE_INSERT in tputc()
When MODE_INSERT is set we'd shift characters on the same
line forward before inserting our character in tputc().

Rian Hunter 4d14d97547 Fix crash due to wide characters
In tputc(), when a character wasn't large enough to fit

the next line. Unfortunately, we weren't resetting our glyph
pointer and this caused memory corruption when a
wide character (width == 2) was being written. This patch
resets our glyph pointer after calls to tnewline().

Ivan Delalande 09f5d98251 Trim trailing whitespaces in every selection case
Trailing whitespaces are trimmed when copying from normal selection and
rectangular selection on lines that have their last character included
or on the left of the selection. It leads to inconsistent behaviors when
copying the exact same text from the left and right window in
applications with vertical splits.
This patch solves this issue by always trimming the selection.

CustaiCo 86633ada91 patch for bell in st
The XBell() call currently used when a bell is recieved sends a message
to the X server, but if the X server doesn't know how to sound it,
it just gets ignored and I have not been able to find anywhere in x.org's
code a way to configure the action that the server does.

However, if you use XkbBell() then you can have a process listening for
the XkbBellNotifyEvent that is produced and either alert you visually or
play an audio file or whatever you want as your notification. You have
to include one more header file but the function seems to be compiled as
part of Xlib, at least on my installation.

Roberto E. Vargas Caballero 5afb3862ba Add support for utmp in st
St runs an interactive shell and not a login shell, and it means
that profile is not loaded. The default terminal configuration
in some system is not the correct for st, but since profile is
not loaded there is no way of getting a script configures the
correct values.

St doesn't update the utmp files, this is the job of another
suckless tool, utmp. Utmp also opens a login shell (it is the
logical behaviour when you create a new user record) it is a
good option execute utmp and then get a correct input in
utmp, wtmp and lastlog file, and execute the content of the
profile.

Ben Hendrickson 98a1085d0e Removing wrapping newlines from selection
When getting selected text, lines that were wrapped because of length
ought not include the wrapping newline in the selection.

This comes up, for example, when copying a bash command that is long
enough to wrap from the console and pasting it back into the console.
The extra newline breaks it.

Similiarly, changes behavior when trimming whitespace from the end of a
physical line to only do so if the line does not wrap. Otherwise we are
trimming whitespace from the middle of a logical line, which may change
its meaning.

tclearregion() was clearing regions using spaces and the current
attributes of the terminal. It was correct with all the modes excepct
underline, because they didn't affect the space character, but in
the case of underline it was a problem. A easy way of seeing this
problem is writing this in the last line of the terminal:

	tput smul ; echo first; tput rmul; echo second; echo third

Fist was underlined, and second and third were not underlined, but
the spaces at the right of second was underlined becuause in the

FRIGN a32c5f5726 Refactor xsetcolorname()
I mainly improved the slightly off algorithm used to load colours in the 256-colour-space and
removed unnecessary local values (r,g,b,colour).
"colour" is not necessary as a punchbag for XftColorAlloc[Value,Name], as they don't mess with
the result-adress until they are absolutely sure everything worked out[0].

Being at it, I changed the error-returns for AllocValue to dies (just like in xloadcols()), as
a failure is most likely an OOM-situation you better catch early.
In case of an invalid name everything stays the same.

Similar to xterm or urxvt holding shift before selecting text with the mouse
allows to override copying text. For example in tmux with "mode-mouse on" or
vim (compiled with --with-x), mc, htop, etc.

forceselmod in config.h sets the modifier to use this mode, by default
ShiftMask.

The patch 53105cf modified how control codes were detected, because
it tried to handle also C1 control codes (0x80-0x9f), that have
upper bit to 1, so they are multi byte character in utf8.
Code was checking the value of width in order to known that after
decoding the unicode point had a width of 1 byte, but it as incorrect
because this width is the columnb width.

Roberto E. Vargas Caballero aa35bbd7a1 Cancel DCS with SUB, CAN, ESC or any CC1 code
From http://www.vt100.net/docs/vt510-rm/chapter4:

	*The VT510 ignores all following characters until it receives a
	 SUB, ST, or any other C1 control character.

So OSC, PM and APC sequence ends with a SUB (it cancels the sequence
and show a question mark as error), ST or any another C1 (8 bits)
code, or their C0 (7 bits) equivalent sequences (at this moment we
do not handle C1 codes, but we should). But it is also said that:

	Cancel  CAN
	1/8     Immediately cancels an escape sequence, control sequence,
		or device control string in progress. In this case, the
		VT510 does not display any error character.

	Escape  ESC
	1/11    Introduces an escape sequence. ESC also cancels any escape
		sequence, control sequence, or device control string in
		progress.

noname 02d2df5790 Do not eat ESC character if control string is not properly terminated.
Currently tputc handles the case of too long control string waiting for
the end of control string.

Another case is when there is ESC character is encountered but is not
followed by '\\'.  In this case st stops processing control string,
but ESC character is ignored.

After this patch st processes ESC characters in control strings properly.

Test case:
printf '\e]0;abc\e[1mBOLD\e[0m'

Also ^[\ is actually processed in the code that handles ST.
According to ECMA-048 ST stands for STRING TERMINATOR and is used to
close control strings.

tscrollup and tscrolldown do not use tsetdirt, but their code is
equivalent to

        tsetdirt(orig, term.bot-n);
        tsetdirt(orig+n, term.bot);

tclearregion also marks cleared lines as dirty.
In tscrolldown it sets lines from term.bot-n+1 to term.bot dirty, and in
tscrollup it sets lines from orig to orig+n-1 dirty.

In both functions all lines from orig to term.bot are effectively set
dirty, but in tscrolldown lines from orig+n to term.bot are set dirty
twice, and in tscrollup lines from orig to term.bot-n are set dirty
twice.

These patches make it clear which lines are set dirty and sets them
dirty once in each funciton.

Roberto E. Vargas Caballero 7a4eefe87c Add support for multiple charset definitions
vt100 has support for two defined charset, G0 and G1. Each charset
can be defined, but in each moment is selected only one of both
charset. This is usually used selecting a national charset in G0
and graphic charset in G1, so you can switch between graphic
charset and text charset without losing the national charset
already defined.

st hasn't support for national charsets, because it is an utf8
based terminal emulator, but it has support for graphic
charset because it is heavily used, but it only supports G0,
without understanding G1 selection sequences, which causes some
programs in some moments can print some garbage in the screen.

This patch adds a fake support for multiple charset definitions,
where we only support graphic charset and us-ascii charset, but
we allow more of one charset definition.

This patch allow define G0 until G3 charsets, but only accepts
select G0 or G1, and it accepts some national charset definitions

Egmont Koblinger 8ac0a5f872 Add bracketed paste mode
This patch enables bracketed paste mode (
http://invisible-island.net/xterm/ctlseqs/ctlseqs.html#Bracketed%20Paste%20Mode
).

It's mainly useful for text editors to disable line wrapping and auto
indentation when text is being pasted, rather than typed from keyboard.

On the emulator side, it is supported by at least xterm, urxvt,
gnome-terminal, putty, iterm2; and I have a patch for konsole.

On the application side, vim can be configured easily to handle this, and
I have pending patches for mcedit and joe. Probably many others also
support it.

Michael Forney eae31a532e Fix some bugs in mouse tracking logic
* Button number in X10 mode:

  I believe the button - 1 came from "C b is button - 1" from [0].
  However, above this section, it states

    "Normally, parameters (such as pointer poisition and button number)
     for all mouse tracking escape sequences generated by xterm encode
     numeric parameters in a single character as value+32. For example, !
     specifies the value 1."

  Also, from the description of SGR,

    "The encoded button value in this case does not add 32 since that
     was useful only in the X10 scheme for ensuring that the byte
     containing the button value is a printable code."

  This suggests that we should still add 32 to the button value when in
  MODE_MOUSEX10.

* No button release reporting in X10 mode:

    "X10 compatibility mode sends an escape sequence only on button press,
     encoding the location and the mouse button pressed."

* Fix MODE_MOUSEMOTION:

  Currently, motion reporting is skipped when oldbutton == 3
  (corresponding to no button being pressed). However, oldbutton is
  only set on a button press, which will never be 3.

Mark Edgar 4245ba0d12 Correctly initialize altscreen when defaultbg is not 0.
The alternate screen is not properly initialized when st starts. To see
this, set defaultbg in config.h to anything other than 0 (for example, swap
defaultfg and defaultbg), and run:

./st -e sh -c 'tput smcup; read'

You should see that the top-left 80x24 rectangle is black (or whatever
colorname[0] is), while the rest of the screen (if any) has the desired
colorname[defaultbg] color.

The attached patch fixes this by initializing term.c.attr in tnew() before
calling tresize(). It also removes the unnecessary xcalloc() calls, which
misled me on this bug hunt since it is really tclearregion() which
initializes term.lines and term.alt in tresize().

Eon S. Jeon f3d438b101 Regarding commit 7e3cff3
Hello.

I reviewed and tested commit 7e3cff3, and made a patch that fixes some
problems in it.

1. There's a semicolon after an if statement, which is obviously a
typo.

2. The current way of calculating text position in "xdraws" yields
inconsistent results in some cases. This is due to the use of
"font->width", which varies. Instead, "xw.cw" has to be used as the
character width.

Sincerely,
Eon

Eon S. Jeon 33ad83d492 Improved font caching
I made a patch that improves the performance of font caching mechanism.
This is based on a funny behaviour of FontConfig: it was handling
FcCharSet in a somewhat unexpected way.

So, we are currently adding "a character" to a new FcCharSet, and then
add it to a FcPattern. However, if we toss the FcPattern to FontConfig,
it loads the entire language(charset) that contains the character we
gave. That is, we don't always have to load a new font for each unknown
character. Instead, we can reused cached fonts, and this significantly
reduces the number of calls to extremely slow FontConfig matching
functions.

One more thing. I found that, in libXft, there's a function called
XftCharExists. XftCharIndex internally calls this function, and
does more stuffs if the character does exist. Since the returned index
is never used in st, we should call XftCharExists instead of
XftCharIndex. Please note that I already made this change in the patch.

Roberto E. Vargas Caballero 6e1c7c8afc Fix match function bugs
There were two problems with match denfinition.

1) There was a forward declaration in the form:

	static inline bool match(uint, uint);

but later the function was defined as:

	inline bool
	match(uint mask, uint state) {

This causes that there were two different functions in the code, one local
and inline, and other inline but extern. All was working without problems
due to we were using -Os, and the compiler was using the extern definition
and it was no expanding the static declaration. If you removed the -Os flag,
then you got linker errors due it was no able to find the static definition
of the static declaration.

2) The mask checking was incorrect because we were doing the test:

	(state & mask) != state

and this test only was saying that at least all the enabled bits of state
were enabled also in mask, but no all the possible bits in mask. This was
the origin of the bug reported by Xavier Cartron, where he said it was
possible activated some shortcuts with some of the modifiers defined in the
config.h file.

all the lines affected by the selection as dirty. Already there is a functon
which perform this task, selclear.
