\modulesynopsis{Python identifier completion for the GNU readline library.}
|
|
|
|
The \module{rlcompleter} module defines a completion function for
|
|
the \refmodule{readline} module by completing valid Python identifiers
|
|
and keywords.
|
|
|
|
This module is \UNIX-specific due to its dependence on the
|
|
\refmodule{readline} module.
|
|
|
|
The \module{rlcompleter} module defines the \class{Completer} class.
|
|
|
|
Example:
|
|
|
|
\begin{verbatim}
|
|
>>> import rlcompleter
|
|
>>> import readline
|
|
>>> readline.parse_and_bind("tab: complete")
|
|
>>> readline. <TAB PRESSED>
|
|
readline.__doc__ readline.get_line_buffer readline.read_init_file
|
|
readline.__file__ readline.insert_text readline.set_completer
|
|
readline.__name__ readline.parse_and_bind
|
|
>>> readline.
|
|
\end{verbatim}
|
|
|
|
The \module{rlcompleter} module is designed for use with Python's
|
|
interactive mode. A user can add the following lines to his or her
|
|
initialization file (identified by the \envvar{PYTHONSTARTUP}
|
|
environment variable) to get automatic \kbd{Tab} completion:
|
|
|
|
\begin{verbatim}
|
|
try:
|
|
import readline
|
|
except ImportError:
|
|
print "Module readline not available."
|
|
else:
|
|
import rlcompleter
|
|
readline.parse_and_bind("tab: complete")
|
|
\end{verbatim}
|
|
|
|
|
|
\subsection{Completer Objects \label{completer-objects}}
|
|
|
|
Completer objects have the following method:
|
|
|
|
\begin{methoddesc}[Completer]{complete}{text, state}
|
|
Return the \var{state}th completion for \var{text}.
|
|
|
|
If called for \var{text} that doesn't include a period character
|
|
(\character{.}), it will complete from names currently defined in
|
|
\refmodule[main]{__main__}, \refmodule[builtin]{__builtin__} and
|
|
keywords (as defined by the \refmodule{keyword} module).
|
|
|
|
If called for a dotted name, it will try to evaluate anything without
|
|
obvious side-effects (functions will not be evaluated, but it
|
|
can generate calls to \method{__getattr__()}) upto the last part, and
|
|
find matches for the rest via the \function{dir()} function.
|
|
\end{methoddesc}
