2014-06-26Remove CEIL macroRoberto E. Vargas Caballero
This macro was not correct in some cases, and it was used only in one place, where we did'nt get any benefit in performance of in size, so the macro is removed and ceilf is used instead of it. The only function needed from math.h is ceilf, so this patch defines the prototype of it instead of including math.h.
2014-06-26Fixed wrong nanosecond factor 10E6.Ivan Delalande
Commit 5edeec1 introduced a wrong factor for nanosecond computation, the correct value is 1E6. Time and timeout values are 10 times less than they should be and this cause high CPU usage. Reported by pyroh on IRC. Thanks! Signed-off-by: Roberto E. Vargas Caballero <k0ga@shike2.com>
2014-06-24Use monotonic clock to prevent timing issuesFRIGN
This patch replaces the gettimeofday()/timeval-system with uses of clock_gettime() with a monolithic clock and timespec-structs. gettimeofday() is not accurate and prone to jumps and POSIX.1-2008 marks it as obsolete. Read more here [0]. The patch should speak for itself and decreases the binary size for me by almost 200K(!).

2014-06-05Refactor selsnap SNAP_WORD.Colona
Refactor the SNAP_WORD part in selsnap, and fix a bug that caused the word delimiters to be ignored if it was at the very beginning or end of a wrapped line. Signed-off-by: Roberto E. Vargas Caballero <k0ga@shike2.com>
2014-06-04Fix rectangular selection.Colona
selsort computes the wrong normalized coordinates when rectangular selection is enabled, causing rectangular selection to only work when going toward either the top left corner, or the bottom right one. Signed-off-by: Roberto E. Vargas Caballero <k0ga@shike2.com>

2014-06-04Make selection consistent over line breaks.Colona
Currently, selection is expanded to the end of the line over line breaks only in regular selection mode, when the line in not empty and when going down and/or right. This covers all the cases including word selection mode, with the exception of rectangular selection because it would make this mode too rigid. This adjustment is made in selsort so I renamed it to selnormalize to better reflect what it does now. Signed-off-by: Roberto E. Vargas Caballero <k0ga@shike2.com>
2014-06-01Fixing color and refactor xsetcolorname.Christoph Lohmann
By the recommendation of FRIGN I refactored xsetcolorname to remove the unnecessary r, g, b variables when allocating a new color. Colors are now freed and set to the new color. A die() should not happen here. Oth‐ erwise it is easy for applications to kill st. St should be resilent to malicious input. Second this patch standardises the naming of »color«. There is no »colour« here. Maybe in some parts of the world.
2014-06-01Revert "Refactor xsetcolorname()"Christoph Lohmann
This reverts commit a32c5f5726f514b49bd396f27aab0e78c40126d3.
2014-06-01Refactor xsetcolorname()FRIGN
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.

2014-05-14Allow mouse selection override using ShiftMaskHiltjo Posthuma
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.

Control code are never displayed. It is not important if graphic charset is displayed or not.
2014-04-29Remove ATTR_GFX and tselcsRoberto E. Vargas Caballero
ATTR_GFX was used long time ago to detect when terminal was in graphic mode. Today graphic mode is implemented using a charset pointer, so ATTR_GFX is not needed anymore because graphic condition can be detected directly checking if current charset is GRAPHICS C0.

Almost of the sequences execute their action in a separate function, which is good because helps to read the full set of sequences faster.
2014-04-28Fix tputc control code handlingRoberto E. Vargas Caballero
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.
2014-04-27Remove repeated initialisation of term.escRoberto E. Vargas Caballero
Once a sequence is completed term.esc must return to 0, so instead of repeating this expression in all the cases is better put it at the end of the block.
2014-04-27Cancel DCS with SUB, CAN, ESC or any CC1 codeRoberto E. Vargas Caballero
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.

2014-04-26Do not eat ESC character if control string is not properly terminated.noname
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.
