Adding Readline Functionality Without Recompiling Python

I recently upgraded to Ubuntu 10.04 LTS and refreshed my Python environment. I installed Python 2.7 from source. Unfortunately, I didn't notice that Setup.dist has the readline line commented out by default - by default, there is no readline support installed. I'm now using the Python interpreter as a REPL enough that the constant ^[[...

How do I properly reference the GNU readline library to scan terminal input?

I am attempting to compile C code that utilizes the following within GNU readline. #include <readline/readline.h>; #include <readline/history.h>; I've tried changing the <> to "" and compiling both with and without the -lreadline options. Nothing seems to work. When compiling without -lreadline under gcc results in the following being...

C# why is it skipping my console.readline() ??

So the program is working correctly, but for some reason, on the second time through, it is skipping the Console.ReadLine() prompt altogether. I ran through debug and confirmed that it isn't a loop problem as it is actually entering the method, displaying the WriteLine then completely skipping over the ReadLine, thus returning a blank ba...

readline clash with child printf?

In Linux, readline() in an infinite loop repeatdly reads text\n. However, as soon as child processes start printing to the screen, readline no longer reads new lines. Even if I repeatdly press enter, readline() doesn't return. Anyone know what's wrong? Code sample as requested: char* input; int cpid; while(1) { input = readline("...

Yanking text from the previous stdout onto the command line.

I'd like to set up my Bash in such a way that I could yank text from the previous command's stdout. The example use case I'll use is resolving conflicts during a git rebase. $ git status # Not currently on any branch. # Unmerged paths: # (use "git reset HEAD <file>..." to unstage) # (use "git add/rm <file>..." as appropriate to mark...

How can I add a command to the Python interactive shell?

I'm trying to save myself just a few keystrokes for a command I type fairly regularly in Python. In my python startup script, I define a function called load which is similar to import, but adds some functionality. It takes a single string: def load(s): # Do some stuff return something In order to call this function I have to ty...

Why does my python interactive console not work properly?

I made a very simple interactive console that I'd like to use in a complicated scraping application. It looks like this: #!/usr/bin/env python # -*- coding: utf-8 -*- import os, sys, codecs, code sys.__stdout__ = codecs.getwriter('utf8')(sys.__stdout__) sys.__stderr__ = codecs.getwriter('utf8')(sys.__stderr__) if 'DEBUG' in os.environ...
