Scintilla-based Text Editor and Corrector |
|
|
|
SciTECO is an interactive TECO dialect, similar to Video |
|
TECO. It also adds features from classic TECO-11, as well as |
|
unique new ideas. |

The basic approach to text editing is both radically differ- |
|
ent and surprisingly similar to popular editors like Vi or |
|
EMacs. Instead of using mostly keyboard commands to modify text |
|
in a visual manner, in SciTECO you edit a program (called |
|
macro) using very few keyboard commands (called immediate edit- |
|
ing commands). This program edits text for the user and is exe- |
|
cuted immediately, as far as possible. For instance, moving the |
|
cursor to the right can be done immediatly via the "C" command |
|
which is a part of the editor language. The language is the ed- |
|
itor so to speak. When you delete a character from the end of |
|
the command line macro (called rubout), the side-effects of |
|
that character which may be a command or part of a command, are |
|
undone. |
|
|
|
SciTECO can also be used as a scripting language. The fol- |
|
lowing program calculates the value of PI: |
|
|
|
\Un Qn"= 20Un ' 0Uh 0Uv HK |
|
Qn< J 0Uq Qn*10/3Ui |
|
Qi< (\+2)*10+(Qq*Qi)Ua 0L :K$ Qi*2-1Uj Qa/QjUq |
|
Qa-(Qq*Qj)-2\ 10@I// -%i > |
|
Qq/10Ut Qh+Qt+48Uw Qw-58"= 48Uw %v$ ' Qv"N Qv-^^0= ' QwUv |
|
