TECO
|
|
|
|
/teekoh/ , n.,v. obs. 1. [originally an acronym for [paper] Tape Editor and
|
|
COrrector ; later, Text Editor and COrrector ] n. A text editor developed at
|
|
MIT and modified by just about everybody. With all the dialects included,
|
|
TECO may have been the most prolific editor in use before EMACS , to which
|
|
it was directly ancestral. Noted for its powerful programming-language-like
|
|
features and its unspeakably hairy syntax. It is literally the case that
|
|
every string of characters is a valid TECO program (though probably not a
|
|
useful one); one common game used to be mentally working out what the TECO
|
|
commands corresponding to human names did. 2. vt. Originally, to edit using
|
|
the TECO editor in one of its infinite variations (see below). 3. vt.,obs.
|
|
To edit even when TECO is not the editor being used! This usage is rare and
|
|
now primarily historical. As an example of TECO's obscurity, here is a TECO
|
|
program that takes a list of names such as: Loser,J.Random Quux,TheGreat
|
|
Dick,Moby sorts them alphabetically according to surname, and then puts the
|
|
surname last, removing the comma, to produce the following: MobyDick
|
|
J.RandomLoser TheGreatQuux The program is [1J^P$L$$ J.
|
|
-Z;.,(S,$-D.)FX1@F^B$K:LI$G1L $$ (where ^B means Control-B (ASCII 0000010)
|
|
and $ is actually an alt or escape (ASCII 0011011) character). In fact, this
|
|
very program was used to produce the second, sorted list from the first
|
|
list.
