2012-10-07Add DEC alignment testRoberto E. Vargas Caballero
This sequence was used by DEC personal in to for verifying the screen adjust of terminals. It is the unique test sequence implemented by all the emulators, and I think it is because they want be conforms with vttest which uses this sequence in some tests. --- st.c | 31 +++++++++++++++++++++++-------- 1 file changed, 23 insertions(+), 8 deletions(-)
2012-10-07Avoid initialization of vt100_0 in each call to tsetcharRoberto E. Vargas Caballero
If vt100_0 is a automatic variable then it is initializated in each call to tsetchar, but if the variable is static it is initializated only in compile time. --- st.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
2012-10-07Fix Identification sequencesRoberto E. Vargas Caballero
Do not send NUL character in the identification (use (sizeof(VT102ID) - 1), and finish the sequence once you execute it. --- st.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-)
2012-10-06Add DA and DECID sequencesRoberto E. Vargas Caballero
These sequences are used by the host in order to can detect which kind of terminal is connected. St will answer like a vt102 terminal with this patch. --- st.c | 9 +++++++++ 1 file changed, 9 insertions(+)

2012-10-06Print control codes only in graphic modeRoberto E. Vargas Caballero
Non handled codes must be ignored, except in graphic mode. Also STR sequences have higher priority than control codes, so they must be handled before of them. --- st.c | 160 ++++++++++++++++++++++++++++++++++++------------------------------ 1 file changed, 87 insertions(+), 73 deletions(-)
2012-10-06Add SI and SO control codesRoberto E. Vargas Caballero
SI and SO allows change the G0 and G1 selection. This implementation is not full vt100 compatible, but it is complatible with linux virtual terminal implementation. For full vt100 compatibility we need remake a lot of stuff relate to the different charmaps. --- st.c | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-)

2012-10-06Add documentation to control codesRoberto E. Vargas Caballero
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(-)
2012-10-06Forgot to remove the xclearborders() definition from the last commit.Christoph Lohmann
2012-10-06Removing the xclearborders() hack. St now cleans up the parts of the border,Christoph Lohmann
if something needs to be drawn close to it.
2012-10-06The style inquisition was here. Yes, making it a unified style. The lastChristoph Lohmann
infidels will be squashed too!
2012-10-05Adding the patch of David Dufberg Töttrup to implement WM_DELETE_WINDOW. ↵Christoph Lohmann
Thank you!
2012-10-05Fixing the brightening on bold. For the 256 colors and greyscale I assumed aChristoph Lohmann
reasonable solution.
2012-10-05When the drawing behaviour was changed underline was not corrected.Christoph Lohmann
Thanks to Peter A. Shevtsov!
2012-10-04This adds the fontcache dependency to try something out. Additionally theChristoph Lohmann
invert mode now works as expected. In the config.def.h autohint is set to false, so the fonts are drawn correctly, without any overlapping.
2012-10-02Thanks to c00kiemon5ter. Not changing bold to bright colors seems to be theChristoph Lohmann
right choice.
2012-09-30This changes -f to be the parameter for the font. Now -f is -o.Christoph Lohmann
The parameters were reordered according to the alphabet too.
2012-09-30Remove the cruft of the user to have to define the different font styles.Christoph Lohmann
2012-09-29We need all the colors to be available, so die() on some not available.Christoph Lohmann
This is a new opportunity to see if X11 somewhen handled colors in a strange way.
2012-09-29All xcolors are not Xft colors and the clearing of the borders has beenChristoph Lohmann
optimized. There is a speedup when resizing windows.
2012-09-27Vt escape sequences allow escape sequences in escape sequences and escapeChristoph Lohmann
sequences, so we have to support escape sequences in escape sequences that escape sequences in escape sequences – setting a title won't notify you anymore.
2012-09-26Allow control characters inside escape sequencesRoberto E. Vargas Caballero
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(-)
2012-09-26Ignore all control characters not handledRoberto E. Vargas Caballero
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(-)

2012-09-25Fix bug in tputc writing to io fileRoberto E. Vargas Caballero
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(-)
2012-09-24The xinit() call needs to be behind all the tty init, otherwise all theChristoph Lohmann
allocated structures are wrong. The xclear() is now done on purpose. Please keep X11 calls out of the way of pure tty-related calls.
2012-09-24Add some documentetion to tsetmodeRoberto E. Vargas Caballero
The names of the terminal modes supported by vt102 are (taken from the VT220 programmer reference manual): Table 4-7 ANSI-Standardized Modes Name Mnemonic Parameter (Ps) Error (ignored) - 0 (3/0) Keyboard action KAM 2 (3/2) Insert/replace IRM 4 (3/4) Send/receive SRM 12 (3/1 3/2) Line feed/new line LNM 20 (3/2 3/0) Table 4-8 ANSI-Compatible DEC Private Modes Name Mnemonic Parameter (Ps) Error (ignored) - 0 (3/0) Cursor key DECCKM 1 (3/1) ANSI/VT52 DECANM 2 (3/2) Column DECCOLM 3 (3/3) Scroll DECSCLM 4 (3/4) Screen DECSCNM 5 (3/5) Origin DECOM 6 (3/6) Auto wrap DECAWM 7 (3/7) Auto repeat DECARM 8 (3/8) Printer form feed DECPFF 18 (3/1 3/8) Printer extent DECPEX 19 (3/1 3/9) Text cursor enable DECTCEM 25 (3/2 3/5) National replacement character sets DECNRCM 42 (3/4 3/2) This patch adds a comment for each one of these sequences. --- st.c | 26 +++++++++++++++++++++----- 1 file changed, 21 insertions(+), 5 deletions(-)

2012-09-24Clear X window in tsetreset()Roberto E. Vargas Caballero
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(-)

2012-09-17Fixing the redrawing patch of k0ga, so it's using xclear() in redraw() too.Christoph Lohmann
2012-09-17Clean windows display after resizingRoberto E. Vargas Caballero
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(+)
2012-09-17Copy non set positions as spacesRoberto E. Vargas Caballero
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(-)

2012-09-16Preliminary solution to the stuttering problem.Christoph Lohmann
2012-09-16Fix selection bugRoberto E. Vargas Caballero
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(-)
2012-09-16Render only once in each main loop iterationRoberto E. Vargas Caballero
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(-)
