PiotrLegnica's Stuff

You might find some of those useful. Or not. Released under WTFPL license, unless source says otherwise. And it probably requires Windows and Python 2.6 anyway.

I also have my own django-trunk-patches patch queue.

What's inside

bigints-add.cpp

Written one day (for SPOJ probably) - very basic and very naive implementation of bigint addition in C++, using std::list<char> (i.e. a linked list of digits) as integer type. Uses base-10 internally, so it requires some memory, but it works. I'm pretty sure there's much room for improvement.

brainfuck.py

My awesome Brainfuck compiler. Generates flat assembler source code for either Linux (using ELF formatter and syscalls for I/O) or Windows (using PE console formatter and msvcrt's getchar/putchar for I/O).

cpp-comments-filter.cpp

Like above; removes C++ comments (single- and multiline) from stdin, and outputs result to stdout, using simple state machine. Probably can be improved, too.

dns.py

A (very) prototype (proof-of-concept) DNS records management util. Not very useful in itself, but comes with tinydns record file generator - with support for SRV records! It's ZODB3 powered (pretty heavy for such a small script, huh?), and has some level of input validation (I'm open to more suggestions!). Usage:

dns.py dom add <domain> - adds domain
dns.py dom del <domain> - removes domain

dns.py rec <domain> <type> <subdomain> - adds record <type> for <subdomain>.<domain>
<subdomain> may be empty, or a wildcard (*).

dns.py data - generates tinydns-data-compatible data file

du.py

A "disk usage" script, that can render nice colored tree, and shows progress as it counts. Usage: du.py <path> [<max. tree nesting>]. If tree nesting is not given, tree is not rendered. I use it often, so it definitely works.

dummy.c

A "do nothing" /SUBSYSTEM:WINDOWS program. I use this as "debugger" for applications that I don't want to run at all. Just create a REG_SZ named Debugger under HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\<application>.

HLQuery.py, HLQuery1.py

Two versions of UDP HLDS server query library. Written in January 2008, and used somewhere around then for Counter-Strike 1.6 server monitor. I have no idea why there are two versions, and which one works better. Go ahead and try.

icon.cpp

Written as an overblown example of GetClassLong - an icon stealer application. It opens given PID, fetches icon of process' first window, and creates its own micro-window with that icon. It's cool, but might not work with every application, as it does very limited window enumeration. Usage: icon <pid>.

jobs.cpp

Written as an example - Windows' job objects. Watch with Process Explorer to see it.

m3u-to-pls.py

Simple M3U to PLS converter. Supports multiple file input and URL fetching.

make-fourcc.py

Small util to convert four character code into big- or little-endian hex integer constant. Usage: make-fourcc.py XXXX [little/big]. Little endian is default.

myepisodes.py

MyEpisodes.com RSS to iCalendar converter. Old and not so beautiful, but does the job. Requires Python 2.5, icalendar and feedparser. CGI script for now (I'm very slowly working on WSGI-compliant rewrite).

qa.py

Small self-test application - I used it to learn e.g. German irregulars, by repeating them over and over. Supports UTF-8 (obviously), but you might need to change console codepage. It reads simple database in format correct answer :: question, shuffles the questions, logs progress, and displays correct percentage (i.e. it's neat and cool). Code probably sucks, but who cares, it works. And it's been tested with py2exe.

scheduler.py

Very, very, very simple "task scheduler" (there's maybe 20 lines of real code). Probably requires Python 2.5, but who knows.

seh.c

Written as an example - the simplest SEH unhandled exception catcher ever.

tree.cpp

Simple non-templated tree written for somebody as simple way to hold directory hierarchy. There are absolutely no error-handling or correct memory management, but shows a simple tree and how to print it recursively just fine, IMHO.

writeColor.py

A portable (I think) "writeColor" function, which uses either Console API on Windows, or ANSI escape codes on other platforms. Usage: writeColor(text, foreground, background, terminator), where background and terminator are optional (terminator defaults to \n). Probably could be improved, feel free to send patches. See code for color table (append "-bold" to use brighter versions).
