26
27 \brief Mediator between Widget and Screen.
28
29 This class is responsible to scan the escapes sequences of the terminal
30 emulation and to map it to their corresponding semantic complements.
31 Thus this module knows mainly about decoding escapes sequences and
32 is a stateless device w.r.t. the semantics.
33
34 It is also responsible to refresh the Widget by certain rules.
35
36 \sa Widget \sa Screen
37
38 \par A note on refreshing
39
40 Although the modifications to the current screen image could immediately
41 be propagated via `Widget' to the graphical surface, we have chosen
42 another way here.
43
44 The reason for doing so is twofold.
45
46 First, experiments show that directly displaying the operation results
47 in slowing down the overall performance of emulations. Displaying
48 individual characters using X11 creates a lot of overhead.
49
50 Second, by using the following refreshing method, the screen operations
51 can be completely separated from the displaying. This greatly simplifies
52 the programmer's task of coding and maintaining the screen operations,
53 since one need not worry about differential modifications on the
54 display affecting the operation of concern.
55
56 We use a refreshing algorithm here that has been adoped from rxvt/kvt.
57
58 By this, refreshing is driven by a timer, which is (re)started whenever
59 a new bunch of data to be interpreted by the emulation arives at `onRcvBlock'.
60 As soon as no more data arrive for `BULK_TIMEOUT' milliseconds, we trigger
61 refresh. This rule suits both bulk display operation as done by curses as
62 well as individual characters typed.
63 (BULK_TIMEOUT < 1000 / max characters received from keyboard per second).
64
65 Additionally, we trigger refreshing by newlines comming in to make visual
66 snapshots of lists as produced by `cat', `ls' and likely programs, thereby
67 producing the illusion of a permanent and immediate display operation.
68
69 As a sort of catch-all needed for cases where none of the above
70 conditions catch, the screen refresh is also triggered by a count
71 of incoming bulks (`bulk_incnt').

75 - evtl. the bulk operations could be made more transparent.

36 An arbitrary long scroll.
37
38 One can modify the scroll only by adding either cells
39 or newlines, but access it randomly.
40
41 The model is that of an arbitrary wide typewriter scroll
42 in that the scroll is a serie of lines and each line is
43 a serie of cells with no overwriting permitted.
44
45 The implementation provides arbitrary length and numbers
46 of cells and line/column indexed read access to the scroll
47 at constant costs.
48
49FIXME: some complain about the history buffer comsuming the
50 memory of their machines. This problem is critical
51 since the history does not behave gracefully in cases
52 where the memory is used up completely.
53
54 I put in a workaround that should handle it problem
55 now gracefully. I'm not satisfied with the solution.
56
57FIXME: Terminating the history is not properly indicated
58 in the menu. We should throw a signal.
59
60FIXME: There is noticable decrease in speed, also. Perhaps,
61 there whole feature needs to be revisited therefore.
62 Disadvantage of a more elaborated, say block-oriented
63 scheme with wrap around would be it's complexity.

22/*! \class Screen
23
24 \brief The image manipulated by the emulation.
25
26 This class implements the operations of the terminal emulation framework.
27 It is a complete passive device, driven by the emulation decoder
28 (TEmuVT102). By this it forms in fact an ADT, that defines operations
29 on a rectangular image.
30
31 It does neither know how to display its image nor about escape sequences.
32 It is further independent of the underlying toolkit. By this, one can even
33 use this module for an ordinary text surface.
34
35 Since the operations are called by a specific emulation decoder, one may
36 collect their different operations here.
37
38 The state manipulated by the operations is mainly kept in `image', though
39 it is a little more complex bejond this. See the header file of the class.

102/* Incoming Bytes Event pipeline
103
104 This section deals with decoding the incoming character stream.
105 Decoding means here, that the stream is first seperated into `tokens'
106 which are then mapped to a `meaning' provided as operations by the
107 `TEScreen' class or by the emulation class itself.
108
109 The pipeline proceeds as follows:
110
111 - Tokenizing the ESC codes (onRcvChar)
112 - VT100 code page translation of plain characters (applyCharset)
113 - Interpretation of ESC codes (tau)
114
115 The escape codes and their meaning are described in the
116 technical reference of this program.
117*/
118
119// Tokens ------------------------------------------------------------------ --
120
121/*
122 Since the tokens are the central notion if this section, we've put them
123 in front. They provide the syntactical elements used to represent the
124 terminals operations as byte sequences.
125
126 They are encodes here into a single machine word, so that we can later
127 switch over them easily. Depending on the token itself, additional
128 argument variables are filled with parameter values.
129
130 The tokens are defined below:
131
132 - CHR - Printable characters (32..255 but DEL (=127))
133 - CTL - Control characters (0..31 but ESC (= 27), DEL)
134 - ESC - Escape codes of the form <ESC><CHR but `[]()+*#'>
135 - ESC_DE - Escape codes of the form <ESC><any of `()+*#%'> C
136 - CSI_PN - Escape codes of the form <ESC>'[' {Pn} ';' {Pn} C
137 - CSI_PS - Escape codes of the form <ESC>'[' {Pn} ';' ... C
138 - CSI_PR - Escape codes of the form <ESC>'[' '?' {Pn} ';' ... C
139 - VT52 - VT52 escape codes
140 - <ESC><Chr>
141 - <ESC>'Y'{Pc}{Pc}
142 - XTE_HA - Xterm hacks <ESC>`]' {Pn} `;' {Text} <BEL>
143 note that this is handled differently
144
145 The last two forms allow list of arguments. Since the elements of
146 the lists are treated individually the same way, they are passed
147 as individual tokens to the interpretation. Further, because the
148 meaning of the parameters are names (althought represented as numbers),
149 they are includes within the token ('N').
