Introduction

In a traditional UNIX installation a single machine (host) served several users by means of terminals attached to this host by a serial cable. These terminals (end points) where specialized devices, either regular ttys (printer with keyboard) or later more sophisticated things with cathode ray tubes.

Today, hardware has become so cheap, that each single user could be provided with a complete host/display combination for the former price of a terminal.

Additional, and here we come to the X in the emulation, display devices have become graphical while the original terminal where only able to show characters but not graphics.

To allow programs designed for the original configuration to be used in the contemporary setup, "terminal emulations" where invented. In these emulations, the whole original setup is simulated.

The serial cable is folded into the operating system as a sort of loop back device, and a program, the terminal emulation, uses modern means of graphical user interfaces to behave like an earlier terminal. To complete the picture, the host in the diagram is replaced by the application that runs in the emulation (typically a shell or an old editor). So, terminal emulations are in fact interfaces to character oriented applications.

This document describes the implementations of a program named "konsole", which is such an X terminal emulation. Since konsole is distributed under the GPL, meaning that it's source code is available to whoever likes to hack on it, the program would be incomplete without a proper introduction into the code and it's concepts. Thus, this text is to complement the program and the source with the remaining informations to make a complete product.

A first refinement

Before we can come to the actual implementation, quite some notions have to be introduced. We have to get us an idea what a terminal emulation does in more detail.

To this end, a simple model of the terminal and it's operation is given, which is later extended and refined as we come deeper into matter and implementation.

At some level conception, a terminal can be described as a (abstract) data model. This means it has some type of state together with operations on that data type. These operations are somehow encoded to be passed over the serial line.

The concrete model is often loosely named the "emulation", the specific encoding chosen, the "protocol".

There are two principle models in use. The first, stream like one, which is related to a tty, consideres the terminal as an indefinit long and wide sheet of paper on which a printer head types the characters that come in over the line. Typical examples are shell scripts, make and other programs producing sequential protocols of their activity. Their basic data type is a list of list of characters.

The second principle model is used by applications written especially for crt devices, so called full screen applications. These treat the terminal as a matrix of characters where each position can be individually addressed and written to. Typical representatives are full screen editors like vi and emacs, file managers like mc and mail readers like mutt.

Though the second model is newer, it's age does not imply a preference. To the contrary, both models have a right for their own and are both to be supported. The first model is fully expressed within konsole in form of it's ref:history buffer.

Note, that although the second model definitely build on the first one in almost any respect, it cannot fully express it, since it introduces a finite line length, while the first model works with indefinite lines.

Since application with both view of things are typically run within the same session, some effort has been made within konsole to maintain both ideas simultaniously, but only with limited success so far.

In both models, the notion of a current position (historically a printer's head, nowadays visualized by a cursor) is present. "Printing" a character at the current position and advancing the head together with the starting a new line are the most fundamental operations of the emulation.

The full screen model basically adds the possibility to position the cursor and to overwrite and clear the screen.

A plethora of additional (more or less useful) commands are then added on this by every specific emulation, see below for the awful details.

Parts of the model

All the following in this section is an outline.

Parts of the terminal description

Sequences.html Conceptually, the commands to the terminal emulation are encoded if form of byte sequences to meet the restrictions of the transport media. These sequences have pretty different originations and therefore the format of the sequences are inhomogenous.

Refering both to their origin and form, one can group the overall encoding schemes as follows:

.
NamePatternScopeComment
Printable Ascii Characters32..126ASCII ECMA This is the most original pattern of all. The characters to be displayed are passed over the chanel and are interpreted by the terminal (emulation) as instructions to display the corresponding glyph of the ascii character set. Contempory emulations include the upper half (128..255) of the extentions to the national ascii character sets, also.
Ascii Control Characters0..26,28..31,127ASCII ECMA Ascii defines some non-printable, but format effecting characters, too. Depending on the emulation, at least some of them are given a meaning. The typically implemented ones are those that are handled by a teletype like device.
Simple Escape SequenceESC CECMA These sequences are made up from an ESC character followed by exactly one other character in the range ???..???.
CSI Sequence ESC [ Parameters {I} C ECMA

The remaining codes are nonstandard but traditionalized hacks.

DEC hacks ESC C D VT100
XTERM hacks ESC ] Pn ; text BEL XTERM

VT52 uses a different (incompatible) set of escape codes. VT100 includes the VT52 emulation as a mode.

More on Control Sequences

.

Control Characters

. Control characters (codes 0x00 - 0x1f 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 a VT100. The processing of the control sequence then continues with the next character received. The exceptions are: if the ESC character occurs, the current control sequence is aborted, and a new one commences beginning with the ESC just received. If the character CAN (0x0c) or the character SUB (0x0e) occurs, the current control sequence is aborted. The ability to embed control characters allows the synchronization characters XON and XOFF to be interpreted properly without affecting the control sequence.

.

CSI Sequences

.
Control Sequence Introducer (CSI):
An escape sequence that provides supplementary controls and is itself a prefix affecting the interpretation of a limited number of contiguous characters. In the VT100, the CSI is: <ESC>[ .
Parameter:
1. A string of zero or more decimal characters which represent a single value. Leading zeros are ignored. The decimal characters have a range of 0 (060) to 9 (071).
2. The value so represented. .
Numeric Parameter:
A parameter that represents a number, designated by Pn. .
Selective Parameter:
A parameter that selects a subfunction from a specified set of subfunctions, designated by Ps. In general, a control sequence with more than one selective parameter causes the same effect as several control sequences, each with one selective parameter, e.g., CSI Psa; Psb; Psc F is identical to CSI Psa F CSI Psb F CSI Psc F. .
Parameter String:
A string of parameters separated by a semicolon. .
Default:
A function-dependent value that is assumed when no explicit value, or a value of 0, is specified. .
Final character:
A character whose bit combination terminates an escape or control sequence.
. EXAMPLE: Control sequence to turn off all character attributes, then turn on underscore and blink attributes (SGR). .

The octal representation of this string is:

     033 0133 060 073 064 073 065 0155
    <ESC>   [   0   ;   4   ;   5    m
  
. Alternate sequences which will accomplish the same thing: . .

DEC hacks

. These form two groups of commands.

In one first the first character is a hash (#) and the following a digit. This command group is used to denote VT100 specific instructions and can safely be sonsidered to be obsolete. See DECALN, DECDHLB, DECDHLT, DECDWL and DECSWL.

The second one is used to specify character set mappings (see SCS). A CSI instruction to do this is specified in ECMA, and this should be used as a replacement. .

XTERM hacks

ConceptDB.html The following text is a collection of several sorts of definitions and explainations. It is incomplete in many respects and a working draft. .

All of the following control sequences are transmitted from the Host to VT100 unless otherwise noted. All of the control sequences are a subset of those defined in ANSI X 3.64 1977 and ANSI X 3.41 1974.

The following text conforms to these formatting conventions:
