2014-04-25Simplify tdeletechar and tinsertblank and fix memory corruption.noname
Current CSI parsing code uses strtol to parse arguments and allows them to be negative. Negative argument is not properly handled in tdeletechar and tinsertblank and results in memory corruption in memmove. Reproduce with printf '\e[-500@' Patch also removes special handling for corner case and simplifies the code. Removed term.dirty[term.c.y] = 1 because tclearregion sets dirty flag.
2014-04-23Style fixes in tscrollup.noname
2014-04-23Do not set dirty flag twice in tscrollup and tscrolldown.noname
2014-04-23Use tsetdirt in tscrollup and tscrolldown.noname
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.
2014-04-23Fix techo handling of control and multibyte characters.noname
techo compares signed char to '\x20'. Any character with code less then '\x20' is treated as control character. This way characters with MSB set to 1 are considered control characters too. Also this patch makes techo display DEL character as ^?. To reprocuce the bug, enable echo mode using printf '\e[12l', then type DEL character or any non-ASCII character.

2014-04-20move MODBIT to Macros sectionnoname@inventati.org
Patch moves MODBIT to macros section and uses it in tselcs.

2014-04-20remove confusing SERRNO macroMarkus Teich
I found the SERRNO Macro slightly confusing, since you have to look it up, if you don't know it already. A web search showed it does not seem to be any kind of standard. Also there was no reason in the commit log when it was introduced in 2009. As you can see it also leads to new patches, which don't use this macro (probably the author did not know about it).
2014-04-15Simplify techononame@inventati.org
Remove special case for \e because it is handled well by "control code" case.
2014-04-15typedefs instead of #definesnoname@inventati.org
Replaced #defines with typedefs where possible, patch attached.
2014-04-15fix cursor handling when alt screen is disabledq@c9x.me
I don't like this alt screen thing, but when allowaltscreen == 0, the cursor is still saved and restored after calling 'less' (or 'man'). This patch makes allowaltscreen == 0 usable.

2014-03-27new utf decoderDamian Okrasa
This patch replaces current utf decoder with a new one, which is ~50 lines shorter and should be easier to understand. Parsing 5 and 6 sequences, if necessary, requires trivial modification of UTF_SIZ constant and utfbyte, utfmask, utfmin, utfmax arrays.

2014-03-06Add sequence for printing the current selectionRoberto E. Vargas Caballero
This is very usefull in order to can select what is sent to the plumber.
2014-03-06Add key definition for printer sequencesRoberto E. Vargas Caballero
These new combinations generate the same behaviour (basically) of vt102. It is a good way of communicating st with other programs. [0] http://www.vt100.net/docs/vt102-ug/chapter2.html
2014-03-06Add MC for the full screenRoberto E. Vargas Caballero
This sequence is very useful because allows comunicate the content of the terminal to another program.
2014-03-06Add MC for a single lineRoberto E. Vargas Caballero
This sequence print the current line. It is different to the 'printer on' sequence, where all the characters that arrive to the terminal are printer. Here only the ascii characters are printed.
2014-03-01Style cleanup.Christoph Lohmann
Add some note about the main reason why st is still that big.
2014-03-01Style matters.Christoph Lohmann
2014-02-22Add MC sequenceRoberto E. Vargas Caballero
This sequence control when the printer is enabled or disabled. This sequence control the behaviour of the -o option.
2014-02-08Add xstrdup functionRoberto E. Vargas Caballero
Since we are using xmalloc, xrealloc ..., then it is not logical call directly to strdup. Signed-off-by: Roberto E. Vargas Caballero <k0ga@shike2.com>

2014-02-03Removing the w3img support.Christoph Lohmann
The patch to add w3img support destroys our way to handle fps and so stop wasting resources on fast scrolling. Due to w3img being a hack to display images in an ugly way, is there no need to support this. Use some real way to display images.
2014-02-02Remove non defined behaviour in selcopyRoberto E. Vargas Caballero
It is not defined when lateral effects of expressions are calculated, so an expression as: --last >= gp && !(selected(last - gp, y) is non portable.
2014-02-02Remove duplicated code in strhandleRoberto E. Vargas Caballero
The error condition was duplicated in two different switches. This new version centralized the error handling in only one place.
2014-01-21Use character scaling in XCopyAreaEric Pruitt
2014-01-16Make w3mimgdisplay work with stAmadeusz Sławiński
Before this patch draw() calls drawregion which calls xdraws and then updates whole window in one call thus overdrawing anything drawn by w3mimgdisplay. After moving XCopyArea to xdraws it only updates the regions which are being updated by XftDraw* functions. It may do a few more calls to XCopyArea with this patch.

2014-01-03Fix truecolor escapes, when both bg and fg are setAmadeusz Sławiński
for example echo -e "\e[48;2;255;0;0m\e[38;2;0;0;255m test " should render on red bg with blue fg also now elinks works correctly when using 'truecolor' option in preferences Signed-off-by: Amadeusz Sławiński <amade@asmblr.net>
2014-01-03query pixel size from matched fontEon S. Jeon
Sorry for another duplicated mail. I found the patch is malformed significantly. I've been away from my laptop for a while, so I'm quite unfamiliar with the settings on this system...
2013-12-18Prevent resizing stdinEon S. Jeon
This fixes a bug that the parent tty gets resized whenever you launch st through command line. The problem was that ioctl was resizing cmdfd before it gets initialized in ttynew. Since cmdfd is a global variable, its initial value is 0, and consequently stdin was being resized.
2013-12-11Set _NET_WM_PID attributeEric Pruitt
2013-11-25Add stdint includeRené Rietz
Since st is using now int32_t and uint32_t the inclusion of stdint or inttype is mandatory, because in other case the definition of these new types will not be known by the compiler.
