NAME
complete - file name completion
SYNOPSIS
include "complete.m";
complete := load Complete Complete->PATH;
Completion: adt {
advance: int; # whether forward progress has been made
complete: int; # whether the completion now represents a file or directory
str: string; # string to advance, suffixed " " (file) or "/" (directory)
nmatch: int; # number of files that matched
filename: array of string; # their names
};
init: fn();
complete: fn(dir, s: string): (ref Completion, string);
DESCRIPTION
Complete implements file name completion.
Init must be called before any other operation of the mod-
ule.
Given a directory dir and a string s, complete returns a
tuple (c, err), where c is an analysis of the file names in
that directory that begin with the string s. The field
nmatch will be set to the number of files that match the
prefix and filename will be filled in with their names. If
the file named is a directory, a slash character will be
appended to it. On an error, c is nil and err is a diagnos-
tic string.
If no files match the string, nmatch will be zero, but
complete will return the full set of files in the directory.
The flag advance reports whether the string s can be
extended without changing the set of files that match. If
true, str will be set to the extension; that is, the value
of str may be appended to s by the caller to extend the
embryonic file name unambiguously.
The flag complete reports whether the extended file name
uniquely identifies a file. If true, str will be suffixed
with a blank, or a slash and a blank, depending on whether
the resulting file name identifies a plain file or a direc-
tory.

DIAGNOSTICS
The complete function returns a nil reference and a diagnos-
tic string if the directory is unreadable or there is some
other error.
