* Add documentation to control codesRoberto E. Vargas Caballero2012-10-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the documentation from the vt100 manual programmer: Control Octal Action Taken Character Code ------------------------------------------- NUL 000 Ignored on input (not stored in input buffer; see full duplex protocol). ENQ 005 Transmit answerback message. BEL 007 Sound bell tone from keyboard. BS 010 Move the cursor to the left one character position, unless it is at the left margin, in which case no action occurs. HT 011 Move the cursor to the next tab stop, or to the right margin if no further tab stops are present on the line. LF 012 This code causes a line feed or a new line operation. (See new line mode). VT 013 Interpreted as LF. FF 014 Interpreted as LF. CR 015 Move cursor to the left margin on the current line. SO 016 Invoke G1 character set, as designated by SCS control sequence. SI 017 Select G0 character set, as selected by ESC ( sequence. XON 021 Causes terminal to resume transmission. XOFF 023 Causes terminal to stop transmitted all codes except XOFF and XON. CAN 030 If sent during a control sequence, the sequence is immediately terminated and not executed. It also causes the error character to be displayed. SUB 032 Interpreted as CAN. ESC 033 Invokes a control sequence. DEL 177 Ignored on input (not stored in input buffer). -------------------------------------------- --- st.c | 28 +++++++++++++++++++--------- 1 file changed, 19 insertions(+), 9 deletions(-)

* Allow control characters inside escape sequencesRoberto E. Vargas Caballero2012-09-26
| | | | | | | | | | | | Taken from vt100 manual programmer: Control characters (codes \0 to \37 inclusive) are specifically excluded from the control sequence syntax, but may be embedded within a control sequence. Embedded control characters are executed as soon as they are encountered by the VT100. The processing of the control sequence then continues with the next character received. --- st.c | 68 +++++++++++++++++++++++++++++++++--------------------------------- 1 file changed, 34 insertions(+), 34 deletions(-)
* Ignore all control characters not handledRoberto E. Vargas Caballero2012-09-26
| | | | | | | | | | | | | Taken from vt100 programmer manual: Control characters have values of \000 - \037, and \177. The control characters recognized by the VT100 are shown in Table 3-10. All other control codes cause no action to be taken. We have to take attention when we are using alternate charset, because in this cases they are not used as control characters. --- st.c | 20 ++++++++++---------- 1 file changed, 10 insertions(+), 10 deletions(-)

* Fix bug in tputc writing to io fileRoberto E. Vargas Caballero2012-09-25
| | | | | | | | | | If -f options is enabled then tputc() writes all the data to a file. Actual code assumes that all the strings in 'c' parameters have always 1 byte length, but this is not always true, because due to utf-8 encoding some characters can have a diferent length. So it is necessary pass string length to tputc in order it can call to write() correctly. --- st.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-)
* The xinit() call needs to be behind all the tty init, otherwise all theChristoph Lohmann2012-09-24

* Clear X window in tsetreset()Roberto E. Vargas Caballero2012-09-24
| | | | | | | | | | | tsetreset() is called when it is necessary a full initialization of the terminal, so it also should clean the full X window and not only the terminal content. It is necessary change the order of the initialization in main(), and put xinit before of tnew(), because tnew() calls to tsetreset(), and this can cause a call to xreset() with incorrect values. --- st.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-)

* Clean windows display after resizingRoberto E. Vargas Caballero2012-09-17
| | | | | | | | | Some times the size after a resizing is not an exact multiply of a number of characters, so redrawn the screen using the lines and columns of the neww size can cause that some old graphics keep in the screen. Solution is clean all the windows with the background color. --- st.c | 3 +++ 1 file changed, 3 insertions(+)
* Copy non set positions as spacesRoberto E. Vargas Caballero2012-09-17
| | | | | | | | | | | | | | | | | | st selection don't insert in the selection position whose value is not set. This is correct for the positions in the end of the line, but cause some problems in the beginning. For example echo -e 'a\tb' will print in the screen: a b but after selecting and copying in some place you get: ab because positions from 1 to 7 don't have any value. This patch deals all positions without value as blank (even at the end of the line). --- st.c | 17 ++++++++++------- 1 file changed, 10 insertions(+), 7 deletions(-)

* Fix selection bugRoberto 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 iterationRoberto 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 loopRoberto 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 redrawRoberto 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 functionRoberto 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 fflushRoberto 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 wrappersRoberto 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(-)
