textprint: Visually impressive, in only 18K

You can get graphing and plotting functions in the console from a variety of sources. textprint is easily my favorite for simple data arrays, mostly because it can do this, with only 18K:

2015-04-16-6m47421-textprint-01 2015-04-16-6m47421-textprint-02 2015-04-16-6m47421-textprint-03

textprint takes a flat data file as input, and arranges it graphically to fit the terminal without distorting the image. From there, textprint goes from zero-to-60, in about two seconds.

Because on top of a rather bland plotting display, you have the option to pick between about four or five different graphs, including the bar and column charts you see above, and a couple others.

And then, you can shift those displays along the x or y axes, zoom the displays and even “print” the display to a text file that matches what you see on the screen. (I did see some corruption when trying to zoom in too “close,” though.)

So you have essentially a tool to convert data arrays into visual representations, adjust them to your liking, then “print” them in their new format. And all that in only 18K.

textprint is not without shortcomings, but truth be told, I could sift through anything and find small nits to pick at. Color options would be nice, and while it does have onboard help, there aren’t any flag options that I can see. If I could send commands to textprint and have it spit out a “printed” file without the interface, textprint would be doubly useful.

And to be honest, the title “textprint” is a slight misnomer. That’s going to get lost in the endless array of pdf converters, ASCII readers and document translators that already pepper the ‘web. It needs a more accurate, and more descriptive title.

It’s still exceptionally impressive though. And the fact that it has so many options in such a small space. And seeing that it’s a dozen years old and still working is noteworthy too.

Not in Arch/AUR or Debian that I could find. textprint is bundled with a precompiled binary, but it’s going to look for an ncurses library that didn’t exist on my Arch system. The command to compile it is in the readme.txt file.

    For good plots in text terminal, I prefer gnuplot, with terminal “dumb”:

    $ gnuplot
    > set terminal dumb
    > plot sin(x)
    > plot [0:5] x**2 with lines
