bump version to 0.8.1

fix regression by selecting clipboard text "restore the old behaviour that the primary doesn't get deleted by a simple left click" Patch by Daniel Tameling <tamelingdaniel@gmail.com>, thanks!

don't modify argv, use a counter on some platforms (OpenBSD) this changes the exposed argv in tools using the kvm_* interface, such as ps and pgrep.

selextend: clarify: !sel.mode == SEL_IDLE

clipcopy: no need to check for free(NULL), set to NULL after free

minor code-style: whitespace fixes

Fix title initialization

Fix regression from 69e32a6 when setting title.

LICENSE: fix a few years

update LICENSE: major contributors

Makefile: add all files to make dist

bump version to 0.8

use math.h for ceilf

xhints: no need to initialize sizeh

regression: include termios.h for tcsendbreak etc

General cleanup Simplifies logic in a couple places and removes a redundant function call. Signed-off-by: Devin J. Pohly <djpohly@gmail.com>

Reduce visibility wherever possible When possible, declare functions/variables static and move struct definitions out of headers. In order to allow utf8decode to become internal, use codepoint for DECSCUSR extension directly. Signed-off-by: Devin J. Pohly <djpohly@gmail.com>

Limit usage of extern to config.h globals Prefer passing arguments to declaring external global variables. The only remaining usage of extern is for config.h variables which are needed in st.c instead of x.c (where it is now included). Signed-off-by: Devin J. Pohly <djpohly@gmail.com>

Remove x.c dependency on term The xinit function only needs to the rows/cols, so pass those in rather than accessing term directly. With a bit of arithmetic, we are able to avoid the need for term.row and term.col in x2col, y2row, and xdrawglyphfontspecs as well, completing the removal. Term is now fully internal to st.c.

Pull term references out of xdrawcursor Gradually reducing x.c dependency on Term object. Old and new cursor glyph/position are passed to xdrawcursor. (There may be an opportunity to refactor further if we can unify "clear old cursor" and "draw new cursor" functionality.) Signed-off-by: Devin J. Pohly <djpohly@gmail.com>

Move win-agnostic parts of draw/drawregion to st.c Introduces three functions to encapsulate X-specific behavior: * xdrawline: draws a portion of a single line (used by drawregion) * xbegindraw: called to prepare for drawing (will be useful for e.g. Wayland) and returns true if drawing should happen * xfinishdraw: called to finish drawing (used by draw) Signed-off-by: Devin J.

Split mode bits between Term and TermWindow Moves the mode bits used by x.c from Term to TermWindow, absorbing UI/input-related mode bits (visible/focused/numlock) along the way. This is gradually reducing external references to Term. Since TermWindow is already internal to x.c, we add xsetmode() to allow st to modify window bits in accordance with escape sequences. IS_SET() is redefined accordingly (term.mode in st.c, win.mode in x.c). Signed-off-by: Devin J. Pohly <djpohly@gmail.com>

Move CRLF input processing into ttywrite This also allows us to remove the crlf field from the Key struct, since the only difference it made was converting "\r" to "\r\n" (which is now done automatically in ttywrite). In addition, MODE_CRLF is no longer referenced from x.c. Signed-off-by: Devin J. Pohly <djpohly@gmail.com>

Move terminal echo logic into st.c The only thing differentiating ttywrite and ttysend was the potential for echo; make this a parameter and remove ttysend. Signed-off-by: Devin J. Pohly <djpohly@gmail.com>
