💖 tiscr — take a screen shot of a graphing calculator 💖

okay bestie, this is tiscr(1) from the TITools crew, and it's literally the moment your TI calculator becomes the main character 📸✨

🎀 SYNOPSIS 🎀

tiscr [ options ] [ -o output.pbm ]

🦋 DESCRIPTION 🦋

tiscr takes a screen shot of a connected TI graphing calculator. that's it. that's the vibe. 🫶

you can take a screen shot at any time the calculator is turned on and idle. but bestie, lowkey — depending on the circumstances, you might not be able to grab a screen shot while a program is running. just so you know 💅

the output gets written in Portable Bitmap format. if you've got the netpbm tools installed, go peek at pbm(5) for the deets 👑

✨ PROGRAM OPTIONS ✨

  • -o, --output=filename — write the output to filename (PBM format, slay)
  • -A, --full — include the entire screen buffer in the output image, even the parts that aren't shown on the display. ngl this only does anything on the TI-89, so don't come for me if it's a no-op elsewhere 💀
  • -c, --cable=type[:port] — use the link cable you specify. if you don't specify one, tiscr goes hunting for USB cables connected to the system all by itself 🔍

the cable type can be either the full name:

  • GrayLink
  • BlackLink
  • Parallel
  • SilverLink
  • DirectLink
  • VTI
  • TiEmu
  • UsbKernel

or the 3-letter abbreviation:

  • gry
  • blk
  • par
  • slv
  • usb
  • vti
  • tie
  • dev
heads up fr fr: for serial- and parallel-port link cables, you also have to specify a port number. no port, no connection, periodt.
  • -m, --calc=type — use the calculator model you specify. if you leave it out, tiscr will try to figure out the calculator model automatically 🧚 (she's smart like that)
  • --timeout=n — wait up to n milliseconds for the calculator to respond. give her a minute!! ⏳

🌈 OTHER OPTIONS 🌈

  • -v, --verbose — print out details of link operations. the group chat commentary you never asked for, but honestly? kind of obsessed 😭
  • --help — print out program version information. (yes bestie, that's what the original says, we don't make the rules 👀)
  • --version — print out program version information. iconique.

🌸 ENVIRONMENT VARIABLES 🌸

  • TITOOLS_CABLE — default link cable to use, if the -c option is not specified.
  • TITOOLS_CALC — default calculator model to use, if the -m option is not specified.
  • TITOOLS_TIMEOUT — default timeout value in milliseconds.
