There has been some discussion about this off-list. Most of the
discussion has centered around what appropriate tab completion should
be in different cases (what should be offered in the completion
namespace and when).
pydb has been dealt with a number of these issues already (thanks
I would like to continue the discussion here. Here's a quick summary:
- when a line is blank, pdb commands and valid identifiers and
keywords should be included in the namespace.
- if a line does not start with a pdb command, then it is a python
expression and can be completed by rlcompleter, with all valid
identifiers and keywords available in the namespace.
- if a line does start with a pdb command then we should decide on
the best way to complete each pdb command.
" "[complete] -> all possible commands, identifiers and keywords
"b"[complete] -> "basestring bool break buffer"
"basestring."[complete] -> "basestring.__base__
basestring.__delattr__ ... etc."
"break "[complete] -> whatever the pdb completer will offer
currently, the submitted patch only attempts to complete python
expressions with rlcompleter. I think it would be useful (and more
honest, as Rocky puts it) to offer completion for pdb commands as
well. Apart from general comments, what would be great are suggestions
on what sort of completion should follow the various pdb commands.
