Ec.h describes +"extensible cords", which are essentially output streams that write +to a cord. These allow for efficient construction of cords without +requiring a bound on the size of a cord. + +de.c is a very dumb text editor that illustrates the use of cords. +It maintains a list of file versions. Each version is simply a +cord representing the file contents. Nonetheless, standard +editing operations are efficient, even on very large files. +(Its 3 line "user manual" can be obtained by invoking it without +arguments. Note that ^R^N and ^R^P move the cursor by +almost a screen. It does not understand tabs, which will show +up as highlighred "I"s. Use the UNIX "expand" program first.) +To build the editor, type "make cord/de" in the gc directory. + +This package assumes an ANSI C compiler such as gcc. It will +not compile with an old-style K&R compiler. |
