scripts | A collection of hopefully useful scripts

scripts is a Python library. scripts has no bugs, it has no vulnerabilities, it has a Strong Copyleft License and it has low support. However scripts build file is not available. You can download it from GitHub.

analemma.py: Plot the analemma from the selected location, using PyEphem and PyGTK. androidfiles.py: A Python module to make it easier to list files on an Android device using adb, and copy individual files to the device. Can also synchronize two directories, trying to notice when files need to be moved rather than removed and recopied. Used by podcopy. animate.js: Simple code for animating a series of images in javascript. aptver: Search for Debian packages, installed or uninstalled, matching a pattern, and print out versions and descriptions. balanceparens.py: A very simple parenthesis (and brace and bracket) counter. Why isn't there a better one already on Linux?. birdcodes.py: Give common name for those obscure 4-letter bird codes. bdump: Ascii/hex/decimal dumps of any file. Like od but much more readable. bookfind.py: List books by author optionally year of publication, to find new books by particular authors. browser_cookies.py: Unpack a firefox or chrome/chromium cookie file to show your cookies. cachefile.py: A general class for cases where you need to fetch data from some slow process, like a web API, and cache it locally for speedier access. Caches in CSV format. cairodrawwin.py: A base for building Python3 GTK3/Cairo apps using a drawing area. You can import and subclass it, or use it as a template. cellaut.py: Simple cellular automata simulation in Python. Slow. censusdata.py Functions to help in parsing US decadal census data. chatsounds.py: An xchat Python script to handle nick (and other special-case) sounds. Also a rare example of an xchat Python script. check-monitors A shell script to probe for connected monitors and use xrandr to activate the right one. Obsoleted by monmon.py. cleanhtml.py Clean up HTML edited by gmail users -- remove font/color/style tags and such. Then prettyprint (somewhat -- add newlines, at least). Minimal, but serves as an example for how to clean up HTML: every source may have different types of clutter, so you may need to customize for whatever source you're trying to clean up. colormatch.php: Find the nearest matching color name. comet.py: Look up a comet and compute its position, using Skyfield. conjunctions.py: Predict planetary visibility and conjunctions for a specified date range. countsyl: Count likely syllables in words, giving best guess and likely max. covid-timeseries.py: Plot COVID data from the Corona Data Scraper. Because I'm as obsessed by COVID-19 as everybody else. decodemail.py: Decode email lines encoded in RFC 2047 format, printing only lines that match a specific header (Subject:, From:, etc.). delaytest.cgi: A CGI script in Python that spits out some text slowly, with delays. Use it on your webserver (or localhost) to test things like parallel downloads to make sure they work with slow servers. domaincheck.py: Check for expiring domains, using python-whois. diff2rss: Diff two files and output RSS of the differences. A possible (though poor) solution for web pages that don't offer RSS feeds. diffiles.py: Find files that differ between two directories -- even if they've been moved to different places in the directory structure. dirsneeded.py: Run a program inside strace and check what files and directories are needed during the run. Useful for setting up a chroot. docx2html, doc2html have been replaced by word2html. eggtimer: Pop up a reminder window in a specified number of minutes. epicycle.py: Show planet orbits as they would be viewed from the north ecliptic pole in a geocentric universe. Show the Venus Pentagram, etc. epubtag.py: Display author, title and tag information for ebooks in epub format; or add or modify an ebook's topic tags, title or cover. Can be imported as a module (there are examples in the kobo/ directory and in fixbookcover). falls_between.py: given a day of the week ("tue") or a day of the month (15), did it occur between two given dates?. fincompare.py: Download financial data from Yahoo finance and plot lots of different funds on the same scale. Can also take data from a local spreadsheet or other source. fix_agenda.py: Are you in an organization where everyone lives and dies by MS Word, emailing dozens of Word documents around for every meeting, and you'd like to take that pile of documents for the next meeting and convert them to HTML so they can be shared on a website and viewed in a web browser? That's what this script is for. Requires word2html (in this git repo), python-mammoth, unoconv (a part of Libre Office), and BeautifulSoup. fixbookcover: Fix books whose cover doesn't include the title, like many Project Gutenberg books. fontasia: A Linux font chooser and categorizer.

A solution to the problem of git making it idiotically difficult to keep several machines in sync with the branches in a git repository. gpreso: A lightweight presentation program for displaying HTML slides. Python2/GTK/webkit version. (Previously called preso.). greatcircle.py: Calculate bearings for a great circle trip between two coordinates on a spherical planet. gquickbrowse: Minimal browser: an older version of quickbrowse written in python2-webkit-GTK, now orphaned and no longer available on newer releases. If you don't pass an argument but there's anything in the X selection when you run it, it will use that as initial argument. grebook.sh: A shell script adapted from one by mosh on Stack Exchange to grep in un-DRMed epub (and presumably also mobi) ebooks. grebook.py: A Python version of grebook, mainly useful to show how to implement a multi-stage command pipeline in Python. headerfooter.py: Take standalone HTML files and add customized headers and footers to make them fit in with a website, replacing anything up to and including and following and including. htmlmail.py: Compose and send HTML mail, including image attachments. hypermoon.py: Make up silly names for tonight's moon, as a CGI. icalview.py: Interpret an .ics calendar attachment, including timezones. intel_backlight.py: Tiny script to adjust the backlight on an Intel-based laptop that uses /sys/class/backlight/intel_backlight. imageviewer.py: A generic image viewer widget and image viewer window that can be imported into other python programs. imageviewer3.py: A generic image viewer widget and image viewer window using GTK3 via gi, so they can be used with Python 3. imgcpy.py: Copy a file, suitably downsized, to the clipboard in PNG format so it can be pasted by an app like Discord that uses image pastes. ipsearch: Search for live hosts on the current net, or hosts with a particular port open..

Useful for things like scanning your network to find your Raspberry Pi. mailgrep: Search for patterns in mailboxes, whether they're mbox (uses grepmail) or maildir (uses grep). Bring up mutt on a folder with matching messages. masq: Set up IP masquerading to talk to another computer, such as a Raspberry Pi, over eth0 while using wlan0 for the internet. mbsyncd: isync/mbsync is a good IMAP sync program, but for some bizarre reason it doesn't offer a daemon mode where it syncs regularly forever. So mbsyncd is a daemon wrapper for mbsync. mnist.py: A simple example of a neural net using keras/tensorflow. moncycle.py: Cycle between connected monitors (e.g. laptop display to HDMI). Can be bound to XF86Display in your window manager. monmon.py Probe for connected monitors and their sizes and relative positions.

Replaces and extends check-monitors. moonpos: Predict when the moon (or another body) will be at a specified altitude and azimuth during a specified time window. mouseevent.py: Read mouse events from /dev/input even if not running X, using the python evdev module. Linux only. mpl_smart_dates.py: A smart date locator (ticker) and formatter for matplotlib that can autoadjust according to the amount of time the axis spans. Matplotlib's AutoDateLocator does this for major ticks, but doesn't offer the option of minor ticks. mapping/demraytrace.py: Raytrace a Digital Elevation Model file using povray, creating a 360-degree panorama. demproj.py is similar but pointless, making lots of smaller povray projections that you can stitch together. mapping/grassviewshed.py: Use GRASS r.viewshed for a viewshed analysis on a DEM input file. mapping/polidistmap.py: Show political districts -- or any other geojson data -- on a map using folium to create a leaflet map. Also has examples for using gdal to translate shapefile to geojson. mapping/shapemerge.py: Starting from a shapefile of lots of small shapes, merge (dissolve) them into a smaller number of shapes. For instance, coalesce voting precincts into voting districts each containing several precincts. Uses fiona and shapely. mapping/viewshed2view.py: Take a viewshed (like one generated by GRASS r.viewshed) and turn it into a 360 image showing what's visible. marsoppy.py: Print and plot Mars oppositions using PyEphem. Also an example of how to use the TkInter Canvas with persistent objects. multiplot3d.py: 3D plots in matplotlib of a sequence of functions are so poorly documented, it took me ages to get one working. Here's a simple example. mpcdemo.py: A tiny demo of how to use multiprocess communication in the multiprocessing module to start a worker thread and pass messages to it. musicplayer.py: A little toy music player in Python, illustrating how to play audio. Actually more than a toy now -- I use it as my main music player. noblank: Turn off screen blanking. Run this when you're giving a presentation. Linux-specific. nokeywords: Find directories beneath the present one that don't contain a Keywords or Tags file -- i.e. image directories that need to be tagged with metapho. nonblock.py, nonblock-py3.py: Examples of how to do nonblocking input in Py 2 and Py 3. For code that works in either version, see termsize. noteplayer.py: Spun off of play_chord.py: a more general pygame-based note generator usable asynchronously, like from a Raspberry Pi piano keyboard. oppretro: Several different programs to examine Mars' orbit, and also to experiment with various astronomy libraries. See oppretro/README.md for more details. pathmatch: Search your executable path to find programs matching a string. Like str except you can match patterns anywhere in the string, not just at the beginning. phonewords.py: Map phone numbers to words, or vice versa.

Can also play strings of notes, or can play notes from the keyboard. podcopy: Copy podcasts (fetched with podget) to a mounted mp3 player or directory, or to an Android device via adb. Remove characters in filenames that would cause problems on vfat filesystems, and ensure filenames are unique and files aren't dups. prettysoup: Prettyprint a BeautifulSoup object. Customizable, and avoids problems like BS4 prettify() adding spaces in the middle of words. pulsehelper.py: A script to list or switch audio inputs/outputs on a system that uses PulseAudio. pyclip: Read the X clipboard. pykey.py: Simulate keypresses under X. A simpler, Python version of Crikey, pyplay.py: A class to play sounds asynchronously by calling aplay (or an app of your choice). Don't repeat a sound that's already playing. Used in the xchat script chatsounds.py. pyruler: An X pixel ruler. Useful for measuring things like icon sizes. pysync: Call rsync, but check first what would be changed, and save the password between the two calls. python-cheatsheet.py: Cheatsheet and syntax reminders for useful Python features. qpreso.py: A lightweight presentation program for displaying HTML slides. A Python3/Qt5/QtWebEngine version, since python-gtk-webkit (used for the older gpreso) is no longer supported. randombg: Choose a random background (wallpaper) from a directory named based on current X resolution. So you can have different sets of backgrounds sized for laptop screen, external monitor etc. randomline: Print a random line from a file. Useful for things like choosing a random wallpaper or random system beep tone. readkey.py: Read a key press from the keyboard without waiting for a newline. For CLI programs: doesn't need X, tkintr, pygame or similar libs. repo-pullpush: Modify a git repository, taking the existing URL, making that the pushurl and adding a passwordless pull URL alongside it. rise_set_az.py: Find the times when the sun or moon will rise or set at a specific azimuth, within a specified phase range, from a specified location. scrubjay: Demo of how to use a few different Twitter API. No UI as yet. Two variants: scrubjay-tweepy (tweepy) and scrubjay-p-t (python-twitter). serio: A proof-of-concept serial terminal app in Python.

Can take input from the current X selection, and automatically select its output for pasting into a browser or Twitter window. shorturl-gi3: shorturl ported to python3, GTK3 and GObject introspection (GI). Most useful as an example of how to use GI-GTK3. sieve.py: Visualization of the Sieve of Eratosthenes, using Python curses. (Not very useful, but makes a good curses example.). sinkto: Synchronize files in a list between two machines. Good for syncing updated scripts, dot files, documents, email folders etc. to a laptop when preparing for or returning from a trip, or just for keeping several machines in sync. skyalignments.py: Starting from points in a GPX file, find all combinations of those points that line up with the rising or setting of the sun or full moon around solstices and equinoxes. Meant to show how easy it is for alignments to happen accidentally. speedtestserver: A mini http server that can introduce delays or other glitches that are useful for testing http download clients. Unfortunately, it's only single-threaded which makes it not very useful except as an illustration of how to make a mini server in Python. Use delaytest.cgi for actual testing. starstack.py: Use the astroalign module to align and stack astrophotography images. tee.py: A file-like class that can optionally send output to a log file. termcolors: Display ANSI colors for the current terminal. termsize: Set stty size to the size of the current terminal window, e.g. when logged in to an embedded Posix device over a serial line. tklabelimage.py: Mini example of how to display text and images together in a label in TkInter, and of how to conditionally import Tk in python2 or 3. Doesn't do anything useful. transimageviewer.py: A translucent image viewer (inheriting from imageviewer.py) that passes clicks and other events through to the window below. Useful for things like saving GPS waypoints from a map image. Also offers a rare example of how to use the X11 SHAPE extension from pygtk, including input shapes. turtlefrac.py: Draw fractals (specifically a Sierpinski triangle) as an example of how to use Python turtle graphics. tweet: Play birdsong from a specific bird. Requires ripped tracks from a bird song CD: for example, the Stokes, Cornell or Peterson collections. qhtmlprint: Convert a set of HTML slides (e.g. in navigate.js) into PDF. For turning an HTML presentation into a PDF slide deck. Unfortunately the QtWebkit libraries this depends on seem to be abandoned; see qslide2pdf for a newer version. qslide2pdf: Convert a set of HTML slides (e.g. in navigate.js) into PDF. For turning an HTML presentation into a PDF slide deck. Uses Qt5's QWebEngine and PyPDF2. We'll see how long that's supported. qpdf.py: A simple PDF viewer for Python-Qt5 using popplerqt5. quickbrowse.py: A minimal browser in python-qtWebEngine. Fast and light, supposedly anonymous, no storage of cookies or other identifying information. Useful for things like viewing URLs from mutt or checking websites that don't work well with a Firefox/NoScript profile. Can be used standalone (ln -s /path/to/quickbrowse.py ~/bin/quickbrowse) and/or as a python module for derived browser-based programs. quotekiosk.py: Display a series of plaintext quotes in a large, maybe fullscreen, window, as large as possible to fit in the window, changing the quote every so often. qquotekiosk.py: Display a series of quotes or other content from HTML files, as large as possible to fit in the window, changing the quote every so often, using qpreso.py for the display window. Uses qpreso.py for the HTML display window. urldownloader.py: Maintain a queue of URLs to download asynchronously to local files. us-wars.py: Plot a Gantt chart of years of wars the US has participated in. Also serves as an example of a matplotlib Gantt chart. vcalparse: Parse and print an icalendar/vcalendar/ICS file using python-vobject. viewhtmlmail: Take an mbox HTML message (e.g. from mutt), split it using munpack, and rewrite it so it can be viewed in an external browser. viewmailattachments: Show all attachments to an HTML message in a Firefox window, first running them through unoconv or other conversion programs as needed to convert MS Office formats to HTML or PDF. vol: A simple python-gtk volume slider.
