.TP 5
\fB::tclreadline::readline complete\fP \fIstring\fP
returns 1 if \fIstring\fP is a complete tcl command and 0 otherwise.

.TP 5
\fB::tclreadline::readline customcompleter\fP [\fIstring\fP]
Register the proc \fIstring\fP as custom completer. This proc is called
with exactly four arguments each time completion takes place:
the word to complete ("text"), the "start" and "end" positions of this word
in the line entered so far, and this line ("line"). The custom completion
script should return an array of strings which is a list of completions
for "text".  If there are no completions, it should return an empty
string "".  The first entry in the returned list is the substitution
for "text". The remaining entries are the possible completions. If
the custom completion script returns an empty string and builtin
completion is enabled (see \fBtclreadline::readline builtincompleter\fP),
the builtin completer is called.
\fBtclreadline::readline customcompleter\fP simply returns the current
custom completer if called w/o \fIstring\fP. To turn of custom
completion, call \fBtclreadline::readline customcompleter\fP with
an empty \fIstring\fP.

Example: \fB% puts $b<TAB>\fP will call the custom completer
with the four arguments \fI"$b"\fP, \fI"5"\fP, \fI"8"\fP and \fI"puts $b"\fP.
The custom completer could return a string like "$bl $black $blue", which
will complete "$b" to "$bl" (the longest match) and offer a list of two
further matches "$black" and "$blue".

For further reference, see the proc tclreadline::script_completer in
the file tclreadlineSetup.tcl.

.TP 5
\fB::tclreadline::readline builtincompleter\fP [\fIbool\fP]
enable or disable the builtin completer. If the builtin completer
is enabled, it will be invoked either if there is no custom completer,
or the custom completer returned an empty  string. The builtin
completer is on by default.
\fBtclreadline::readline builtincompleter\fP returns the current
custom completer (also, if called w/o the \fIbool\fP argument).

.TP 5
\fB::tclreadline::readline eofchar\fP [\fIscript\fP]
set a script which will be called, if readline returns the eof character
(this is typically the case if CTRL-D is entered at the very beginning
of the line). The default for this script is "puts {}; exit". Setting
this to an empty value disables any action on eof.
\fBtclreadline::readline eof\fP returns the current eof script.

.TP 5
\fB::tclreadline::readline initialize\fP \fIhistoryfile\fP
initialize the tclreadline interface and read the history from
the \fIhistoryfile\fP. On succes an empty string is returned.
This command has to be called before any other tclreadline commands.


................................................................................

.SH HISTORY
This version of \fBtclreadline\fP is still a development version.
Pretty a lot of features and ideas are not implemented yet. The
reason for this is the lack of time and manpower.
So you are welcome to modify and contribute to the code.
