Need to throw this out somewhere.
The rlcompleter module provides a simple way to get tab completion in the python shell. Unfortunately, that sort of disables the tab key for indentation (although you can do
Ctrl-v TAB). I just wrote this indenting completer to get around that.
When you're at the beginning of a line, or have only whitespace to the left of the cursor, it completes to multiples of four spaces of indentation. Everything else gets passed through to the original completer.
And it goes a little something like this:
#!/usr/bin/env python # Readline-thingamabob for the python shell # 2007-03-02 Filip Salomonsson <firstname.lastname@example.org> import os, readline, rlcompleter, atexit history_file = os.path.join(os.environ['HOME'], '.python_history') try: readline.read_history_file(history_file) except IOError: pass readline.parse_and_bind("tab: complete") readline.set_history_length(1000) atexit.register(readline.write_history_file, history_file) class IndentingCompleter: """Indenting tab completer. Completes to multiples of four spaces for indentation; passes through to original completer when appropriate.""" def __init__(self, completer=None): # Grab the existing completer self.real_completer = completer or readline.get_completer() def complete(self, text, state): import readline # Get the part of the line preceding the cursor line = readline.get_line_buffer()[:readline.get_endidx()] if not text: # No word to complete if not line or line.isspace(): # Indentation only (or start of line) if state > 0: return None # only one suggestion indent_level = (4 - len(line.replace("\t", 8*' ')) % 4) return indent_level * ' ' else: # We're within a line; pass through to real completer return self.real_completer(text, state) # Normal word completion; pass through to real completer return self.real_completer(text, state) readline.set_completer(IndentingCompleter().complete) del os, readline, rlcompleter, atexit, __file__ del history_file, IndentingCompleter
Save it somewhere and put the file's path in your PYTHONSTARTUP environment variable, and you should be good to go. The cross-session 1000-command history comes with the package.
