* simplify loop in tresizeGravatar Quentin Carbonneaux2014-08-19
| | | | Signed-off-by: Roberto E. Vargas Caballero <k0ga@shike2.com>
* Fix man page and usage()Gravatar Roberto E. Vargas Caballero2014-08-17
| | | | | | Man page was repeating -f option, the second time instead of -i, and this option was lost in usage() message. This patch also indent the output of usage().
* Convert VT102ID to a config variableGravatar Roberto E. Vargas Caballero2014-08-15
| | | | | | VT102ID is the sequence that the terminal returns when it is inquired to identify itself. This value should be configurable in the same way that another st parameters.
* Fix portability problem in techo()Gravatar Roberto E. Vargas Caballero2014-08-15
| | | | | | | | | | ISCONTROL chechks if a value is between 0 and 0x1f or between 0x80 and 0x9f. Char signess depends of architecture and compiler, so in some environment the second case is always false (and wrong), Techo() calls ISCONTROL with a char variable, whose type cannot be changed because tpuc() expects a pointer to char, so the solution is to insert a cast in the call to ISCONTROL.

* Unset mode when clearing regionsGravatar Roberto E. Vargas Caballero2014-08-07
| | | | | | | | | | | | | | 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 previous scrool underline mode was set.
* Add error message when child exits whit errorGravatar Roberto E. Vargas Caballero2014-08-04
| | | | | | Master proccess was not showing any error message when the child died with an error, and it was very confusing for the user (for example with incorrect -e command).
* Remove difference between fast and slow blinkingGravatar Roberto E. Vargas Caballero2014-07-31
| | | | | | | | | | One blinking mode is good enough, and two is too much. The best aproach is emulate the fast blinking with the slow blinking, that it is more used. It is removed the flag ATTR_FASTBLINK because it has not a different meaning of ATTR_BLINK, so it is not needed. Signed-off-by: Roberto E. Vargas Caballero <k0ga@shike2.com>
* Fix disabling of bold and fastblinkGravatar Michael Forney2014-07-26
| | | | | | | | | | | | | According to ECMA-48¹ 8.3.117, an attribute value of 21 is "doubly underlined", while 22 is "normal colour or normal intensity (neither bold nor faint)". Additionally, 25 is "steady (not blinking)", which likely means neither slow blink nor fast blink. ¹: http://www.ecma-international.org/publications/files/ECMA-ST/Ecma-048.pdf Signed-off-by: Roberto E. Vargas Caballero <k0ga@shike2.com>
* Fix st with input method.Gravatar Weng Xuetian2014-07-19
| | | | | | | XFilterEvent need to be called against every event, otherwise it would missing some message in the xim protocol and misbehave on some im server. Signed-off-by: Roberto E. Vargas Caballero <k0ga@shike2.com>
* Changed inconsistent indentGravatar Eric Pruitt2014-07-15
| | | | | | | - A line was indented using spaces despite the rest of the code using tabs. Signed-off-by: Roberto E. Vargas Caballero <k0ga@shike2.com>
* Add 8 bit version of DCS, APC, PM, OSCGravatar Roberto E. Vargas Caballero2014-07-08
| | | | | DCS, APC, PM, OSC version for 7 bits environments already was implemented in st. This patch adds the 8 bit version of it.
* Add 8 bit version of HTSGravatar Roberto E. Vargas Caballero2014-07-08
| | | | | HTS version for 7 bits environments already was implemented in st. This patch adds the 8 bit version of it.
* Add 8 bit version of NELGravatar Roberto E. Vargas Caballero2014-07-08
| | | | | NEL version for 7 bits environments already was implemented in st. This patch adds the 8 bit version of it.
* Add 8 bit version of DECIDGravatar Roberto E. Vargas Caballero2014-07-08
| | | | | DECID version for 7 bits environments already was implemented in st. This patch adds the 8 bit version of it.
* Render faint attributeGravatar Anders Eurenius2014-07-08
| | | | | | | | | Faint text is implemented by allocating a new color at one-half intensity of each of the r, g, b components, or if the text bold at the same time, it is not made lighter. Signed-off-by: Roberto E. Vargas Caballero <k0ga@shike2.com> Signed-off-by: Christoph Lohmann <20h@r-36.net>
* Remove all strcmp and strlen calls on Glyph.c[]Gravatar Ivan Delalande2014-07-08
| | | | | | | | | | There were a few occurrences of strcmp and strlen being called on Glyph.c[], which is not always null-terminated (this actually depends on the last values in the buffer s in ttyread()). This patch replace all the calls to strcmp with a test on c[0] directly or a call to tlinelen, and the one to strlen with utf8len. I also took the opportunity to refactor getsel and tdumpline. Signed-off-by: Roberto E. Vargas Caballero <k0ga@shike2.com>
* Render struck-out attributeGravatar Anders Eurenius2014-06-27
| | | | | | | | Implement crossed-out text with an XftDrawRect call, similar to how underline is implemented. The line is drawn at 2/3 of the font ascent, which seems to work nicely in practice. Signed-off-by: Roberto E. Vargas Caballero <k0ga@shike2.com>
* Render invisible attributeGravatar Anders Eurenius2014-06-27
| | | | | | | | | Implement invisible mode by setting the foreground color to be the same as the background color. Not rendering anything would also be an alternative, but this seems less likely to cause surprises in conjunction with any hacks. Signed-off-by: Roberto E. Vargas Caballero <k0ga@shike2.com>
* Reorder and extend glyph attributesGravatar Anders Eurenius2014-06-27
| | | | | | | | | | Faint, invisible, struck and fast blink are added as glyph attributes. Since there's an edit here, let's take the opportunity to reorder them so that they correspond to the two's power of the corresponding escape code. (just for neatness, let's hope that property never gets used for anything.) Signed-off-by: Roberto E. Vargas Caballero <k0ga@shike2.com>
* Remove CEIL macroGravatar Roberto E. Vargas Caballero2014-06-26
| | | | | | | | 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.
* Fixed wrong nanosecond factor 10E6.Gravatar Ivan Delalande2014-06-26
| | | | | | | | | | 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>
* Use monotonic clock to prevent timing issuesGravatar FRIGN2014-06-24
| | | | | | | | | | | | | | 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(!).

* Refactor selsnap SNAP_WORD.Gravatar Colona2014-06-05
| | | | | | | | 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>
* Fix rectangular selection.Gravatar Colona2014-06-04
| | | | | | | | | 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>

* Make selection consistent over line breaks.Gravatar Colona2014-06-04
| | | | | | | | | | | 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>
* Fixing color and refactor xsetcolorname.Gravatar Christoph Lohmann2014-06-01
| | | | | | | | | | | 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.
* Revert "Refactor xsetcolorname()"Gravatar Christoph Lohmann2014-06-01
| | | | This reverts commit a32c5f5726f514b49bd396f27aab0e78c40126d3.
* Refactor xsetcolorname()Gravatar FRIGN2014-06-01
| | | | | | | | | | | | | | | 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.

* Allow mouse selection override using ShiftMaskGravatar Hiltjo Posthuma2014-05-14
| | | | | | | | | | | 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.

* Fix displaying control codeGravatar Roberto E. Vargas Caballero2014-04-30
| | | | | Control code are never displayed. It is not important if graphic charset is displayed or not.
* Remove ATTR_GFX and tselcsGravatar Roberto E. Vargas Caballero2014-04-29
| | | | | | | | 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.
* Do not save cursor in tresize.Gravatar noname2014-04-29
| | | | | | | | | | | This patch fixes the bug introduced in 8f11e1cd034ff28ca47bb4955505db7fa8016ba8 To reproduce the bug: 1. Save cursor: printf '\e[s' 2. Load cursor: printf '\e[u' 3. Resize st window. 4. Load cursor again: printf '\e[u'
