* Fix selection bugGravatar Roberto E. Vargas Caballero2012-09-16
| | | | | | | | | | After the commit named "Remove timeout in the main loop", selection is not working in the proper way. After selecting something, press mouse button in a line outside of selection causes an incorrect highlight. This patch fix the problem forcing a draw after the press event, but this is only a fast hack. Real solution means rewriting selection code. --- st.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-)
* Render only once in each main loop iterationGravatar Roberto E. Vargas Caballero2012-09-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | draw() runs over all lines of the screen and renders only the dirty lines, this avoids render lines which are not modified since last draw() call. In this moment the main loop is something like: - Wait something to read from file descriptors - Read from pseudo tty - Call draw() for rending - Read X events This cause the problem that all the X events that have to update the screen have to call draw() (because draw() is called before of X events handling), so you can have multiples renderings in only one iteration, that will waste a lot of resources. This patch change the main loop to: - Wait something to read from file descriptors - Read from pseudo tty - Read X events - Call draw() for rending So X events don't have to worry about rendering, because draw() is called after them. The only place where draw is called outside of the main loop is in redraw(), but it is necessary for getting a good tput flash. --- st.c | 29 ++++++----------------------- 1 file changed, 6 insertions(+), 23 deletions(-)
* Remove timeout in the main loopGravatar Roberto E. Vargas Caballero2012-09-16
| | | | | | | | | | The main loop waits until there is some data to read in file descriptors of the X server or the pseudo tty. But it uses a timeout in select(), which causes that st awake each 20 ms, even it doesn't have something to do. This patch removes this problem removing the timeout, which is not needed. --- TODO | 1 - st.c | 27 +++------------------------ 2 files changed, 3 insertions(+), 25 deletions(-)
* Call XSync in redrawGravatar Roberto E. Vargas Caballero2012-09-16
| | | | | | | It is necessary call to XSync if you want a good tput flash, because in other way you can not be sure that white screen will be shown. --- st.c | 1 + 1 file changed, 1 insertion(+)
* Call XdbeQueryExtension before of calling any Xdbe functionGravatar Roberto E. Vargas Caballero2012-09-16
| | | | | | | | | | | | | | XdbeQueryExtension() tells to the caller if the Xdbe extension is present in the X server, so it should be called for sanity. But like is said in XdbeQueryExtension(3): No other Xdbe functions may be called before this function. If a client violates this rule, the effects of all subsequent Xdbe calls that it makes are undefined. it is mandatory call this function. --- st.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-)

* Remove buffering to fileio instead of calling fflushGravatar Roberto E. Vargas Caballero2012-09-12
| | | | | | | | | | By default text files are line buffered, and this means that -f option will not write the line until a \n is printed. This is not very useful for debugging, so a call to fflush was added. This patch substitute this call (which will be done by each character painted) by the full remove of the buffering in the file. --- st.c | 12 +++++------- 1 file changed, 5 insertions(+), 7 deletions(-)
* Add xmalloc and xrealloc wrappersGravatar Roberto E. Vargas Caballero2012-09-12
| | | | | | | | | | | | | If malloc or realloc fail they return NULL. Theorically this condition should be tested in the code, but it's a strange condition today (basically if this is hapenning thenyou have a big problem), and even Linux never returns NULL in the default configuration (only if the process don't have room in the space address, something a bit impossible in the case of st). But stis enough small for being executed in low resources computers where this can be a real problem. So the easy way is creating a wrappers function for them and call to die in case of error. --- st.c | 44 +++++++++++++++++++++++++++++++------------- 1 file changed, 31 insertions(+), 13 deletions(-)

* Unhighlight selection when selection is owner by other windowGravatar Roberto E. Vargas Caballero2012-09-05
| | | | | | | | | | | | st marks the active selection using reverse colors in the box selection, but once that another window becomes owner of the selection, it is very confusing that st keeps highlight the old selection. Usually terminal emulators remove the highlight when it is not valid anymore. X sends a SelectionClear event in this situation, so we only have to add a callback which unhighlight the selectin box. --- st.c | 9 +++++++++ 1 file changed, 9 insertions(+)

* Check alternative screen before drawing box selectionGravatar Roberto E. Vargas Caballero2012-09-04
| | | | | | | | | | | | | | | | | | Some programs use the alternative screen (vi, less, ...), whose content is different of the main screen. If you select text in one of the screen, you don't wait the box selection is painted in the other screen, so it is necessary check if the selection was done in the same screen we are going to paint. Before to this commit, you could do something like: $ LESS="" ls | less (select some code) q and selection box remains drawing in the main screen, but the content of selection keeps text of the alternate screen. --- st.c | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-)

* Force redisplay of all lines in DECSCNMGravatar Roberto E. Vargas Caballero2012-09-03
| | | | | | | | | | | | | When it is called DECSCNM all lines become dirty, because it is necessary redraw all lines for getting the new colors. It is easy see the problem running 'echo ^[[?5h'. In order to get a correct flash when running tput flash is necessary wait after DECSCNM, until the changes are displayed, because in other case the switch between reverse on/reverse off will be too much fast and nothing will happen. --- st.c | 12 +++++++++++- 1 file changed, 11 insertions(+), 1 deletion(-)

| | | | | | | | | | This is a theorical feature listed in http://st.suckless.org/goals. All the input/output of the terminal will be written to a file, which can be very useful for debugging, and also allow interconnect st to other process through named pipes. --- st.1 | 6 ++++++ st.c | 14 +++++++++++++- 2 files changed, 19 insertions(+), 1 deletion(-)

* Enable multiple arguments in SM and RMGravatar Roberto E. Vargas Caballero2012-09-02
| | | | | | | | | SM and RM can receive multiple parameters, but the code only was accepting only one. This patch join the code of set and reset modes (SM and RM) in a common function and uses a loop which deals with all the arguments of the sequence. This patch improves xterm and vt100 compability. --- st.c | 180 ++++++++++++++++++++++++++++-------------------------------------- 1 file changed, 76 insertions(+), 104 deletions(-)

* Add CHT sequenceGravatar Roberto E. Vargas Caballero2012-08-29
| | | | | | | This sequence performs "Cursor Forward Tabulation <n> tab stops", which although is not present in vt100 or vt102, xterm accepts it. --- st.c | 5 +++++ 1 file changed, 5 insertions(+)
* Add TBC sequenceGravatar Roberto E. Vargas Caballero2012-08-29
| | | | | | | | | | | | | This sequence clears tab stops in the terminal. If the argument is not present or is zero, then removes the tab stop of the current horizontal position. If the argument is 3 then removes all the tab stops of the terminal. It was necessary modify the terminfo entry tbc, because it has \E[2g instead of the correct \E[3g. Signed-off-by: Roberto E.

* Add HTS sequenceGravatar Roberto E. Vargas Caballero2012-08-29
| | | | | | | | | | | | | This sequence adds a new tab stop in the current horizontal position. This means that tputtab must be look for the next tab stop in the tabs array instead of using a hard coded value offset. Also, CHT sequence XXX message is removed because it is not a vt10x sequence (as far as I know it is a vt50x sequence), and it is not implemented by linux virtual terminal neither by xterm.

* Add tabs field into Term structGravatar Roberto E. Vargas Caballero2012-08-29
| | | | | | | | | | | | Tabs stop are simulated in st using a fixed size of 8, always, without be worried about sequences changing the tab stops. A user can put a tab stop in each horizontal position of the screen, so we need at least one flag for each column of the screen. In the same way as dirty flags is used for the rows, it is used a bool dinamic array. Signed-off-by: Roberto E.
