Decoding means here, that the stream is first seperated into `tokens' which are then mapped to a `meaning' provided as operations by the `TEScreen' class or by the emulation class itself. The pipeline proceeds as follows: - Tokenizing the ESC codes (onRcvChar) - VT100 code page translation of plain characters (applyCharset) - Interpretation of ESC codes (tau) The escape codes and their meaning are described in the technical reference of this program. */ // Tokens ------------------------------------------------------------------ -- /* Since the tokens are the central notion if this section, we've put them in front. They provide the syntactical elements used to represent the terminals operations as byte sequences. They are encodes here into a single machine word, so that we can later switch over them easily. Depending on the token itself, additional argument variables are filled with parameter values. The tokens are defined below: - CHR - Printable characters (32..255 but DEL (=127)) - CTL - Control characters (0..31 but ESC (= 27), DEL) - ESC - Escape codes of the form <ESC><CHR but `[]()+*#'> - ESC_DE - Escape codes of the form <ESC><any of `()+*#%'> C - CSI_PN - Escape codes of the form <ESC>'[' {Pn} ';' {Pn} C - CSI_PS - Escape codes of the form <ESC>'[' {Pn} ';' ... C - CSI_PR - Escape codes of the form <ESC>'[' '?' {Pn} ';' ... C - VT52 - VT52 escape codes - <ESC><Chr> - <ESC>'Y'{Pc}{Pc} - XTE_HA - Xterm hacks <ESC>`]' {Pn} `;' {Text} <BEL> note that this is handled differently The last two forms allow list of arguments. Since the elements of the lists are treated individually the same way, they are passed as individual tokens to the interpretation. Further, because the meaning of the parameters are names (althought represented as numbers), they are includes within the token ('N'). */ #define TY_CONSTR(T,A,N) ( ((((int)N) & 0xffff) << 16) | ((((int)A) & 0xff) << 8) | (((int)T) & 0xff) ) #define TY_CHR___( ) TY_CONSTR(0,0,0) #define TY_CTL___(A ) TY_CONSTR(1,A,0) #define TY_ESC___(A ) TY_CONSTR(2,A,0) #define TY_ESC_CS(A,B) TY_CONSTR(3,A,B) #define TY_ESC_DE(A ) TY_CONSTR(4,A,0) #define TY_CSI_PS(A,N) TY_CONSTR(5,A,N) #define TY_CSI_PN(A ) TY_CONSTR(6,A,0) #define TY_CSI_PR(A,N) TY_CONSTR(7,A,N) #define TY_VT52__(A ) TY_CONSTR(8,A,0) // Tokenizer --------------------------------------------------------------- -- /* The tokenizers state The state is represented by the buffer (pbuf, ppos), and accompanied by decoded arguments kept in (argv,argc).
