* Add support for multiple charset definitionsRoberto E. Vargas Caballero2013-10-021-27/+55
| | | | | | | | | | | | | | | | | | | | | | | 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 but all of them are mapped to us-ascii.

* Fix save/restore cursorMihail Zenkov2013-10-021-7/+8
| | | | | | | st was assuming that save/restore cursor position was independent of the screen that was shown in each moment, but it is not true, because each screen has a different save/restore buffer. This patch fixes it.

* Fix core in multi-line selection on OpenBSDMaurice Quennet2013-09-231-1/+1
| | | | | | | | | OpenBSD 5.3 amd64 release version with the most current st version from git, crash and dump core when selecting multiple lines whith the cursor. This happens, because on line 964 of st.c (gp-1)->mode is accessed, although gp is still pointing at the beginning of the array term.line[y] (see line 939 for initialization of gp).
* Add bracketed paste modeEgmont Koblinger2013-09-231-0/+8
| | | | | | | | | | | | | | | | 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.
* Fix some bugs in mouse tracking logicMichael Forney2013-09-131-9/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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. [0]: http://invisible-island.net/xterm/ctlseqs/ctlseqs.html
* Add audible bellRoberto E. Vargas Caballero2013-09-121-0/+2
| | | | | | | | \a is the character for bell, and st is only marking the window as urgent if it is not active. This patch adds an audible bell which can be disable with bellvolume variable. Signed-off-by: Christoph Lohmann <20h@r-36.net>

* Correctly initialize altscreen when defaultbg is not 0.Mark Edgar2013-09-041-14/+3
| | | | | | | | | | | | | | | | | 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().
* Regarding commit 7e3cff3Eon S. Jeon2013-08-301-3/+3
| | | | | | | | | | | | | | | | | | 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

* Use character size scaling factorsEric Pruitt2013-08-051-7/+13
| | | | | The bounding boxes for characters can be scaled using "cwscale" and "chscale" to scale the width and height respectively.
* Reload colors in resetRoberto E. Vargas Caballero2013-07-201-0/+9
| | | | | | | | | | | Colors definition can be changed using a OSC sequence, so we have to reload them if we want be sure all the colors are the correct. Could be desirable free the colors allocated due to rgb colors and inverse colors (XftColorAllocValues in xdraws), but it is impossible due we use the same structure for all of them.
* Add RGB color definitionRoberto E. Vargas Caballero2013-07-201-34/+85
| | | | | | This patch uses the bit 24 in the color descriptor as an indicator of RGB color, so we can take the values and generating the XftColour directly in xdraws.
* Improved font cachingEon S. Jeon2013-07-191-41/+22
| | | | | | | | | | | | | | | | | | | | 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.

* Fix match function bugsRoberto E. Vargas Caballero2013-07-041-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Remove unneded call to drawRoberto E. Vargas Caballero2013-07-041-1/+0
| | | | | | draw is the function which update the Xwindow with the information st has, and it is designed in a way that it must be called once in the main loop (run function), and calling it in other places it is a waste of time.
* Fix selection clearingRoberto E. Vargas Caballero2013-07-041-9/+5
| | | | | | | | | The way st knows if there is a selection activated is checking if sel.ob.x is equal to -1. In some parts of the code the way of disabling the selection was only setting it to -1, but after it you can't be sure if the selection is clearing from the terminal representation, because it is necessary mark all the lines affected by the selection as dirty. Already there is a functon which perform this task, selclear.
