metro.sh

https://github.com/mitotic/graphterm/raw/master/doc-images/gt-metro.jpg

Output of the metro.sh command, which embeds six smaller terminals within the main terminal, running six different commands from the GraphTerm toolchain: (i) live twitter stream output using gtweet, (ii) weather info using yweather, (ii)i slideshow from markdown file using greveal and reveal.js, (iv) word cloud using d3cloud and d3.js, (v) inline graphics using gmatplot.py, and (vi) notebook mode using the standard python interpreter.

ls vs. gls

Themes

https://github.com/mitotic/graphterm/raw/master/doc-images/gt-screen-dark-theme.png

Showing the basic dark theme, with two embedded terminals to illustrate the contrast with the default and bold themes


stars3d theme, with icons enabled

https://github.com/mitotic/graphterm/raw/master/doc-images/gt-screen-stars3d.png

Showing output of the cat episode4.txt command below the output of the gls command, using the 3D perspective theme. This is actually a working theme, although it is meant for primarily for “show”. Scrolling through a large text file using the vi editor in this theme gives a nice roller coaster effect! (This screenshot was captured with Google Chrome running on Mac OS X Lion, which supports hidden scrollbars. On other software platforms, the scrollbar will be visible.)


Graphical weather forecast using Yahoo Weather API

https://github.com/mitotic/graphterm/raw/master/doc-images/gt-screen-yweather1.png

Showing the screen for the command yweather to illustrate inline HTML form display. Since the location argument is omitted, the form is displayed to enter the location name.

https://github.com/mitotic/graphterm/raw/master/doc-images/gt-screen-yweather2.png

The submitted location information is used to generate a new command, yweather -f  "new york", and execute it for inline weather display.


Inline HTML document display

https://github.com/mitotic/graphterm/raw/master/doc-images/gt-screen-giframe1.png

Showing the screen for the command rs2html README.rst | gframe to illustrate inline HTML document display. The rs2html README.rst command converts a ReStructured Text doument to HTML, writing the output to stdout. The gframe command wraps the HTML in an iframe and displays it inline.


Inline data visualization plotting using matplotlib

https://github.com/mitotic/graphterm/raw/master/doc-images/gt-screen-gmatplot1.png

Showing the screen for the demo program gmatplot.py which generates matplotlib plots as PNG files and displays them inline.


Inline contour plots using matplotlib

https://github.com/mitotic/graphterm/raw/master/doc-images/gt-contourplot.jpg

Inline display of a 2-dimensional filled contour plot of surface air temperature on the globe, generated by matplotlib.


Text editing with emacs

https://github.com/mitotic/graphterm/raw/master/doc-images/gt-screen-emacs.png

Showing the screen for the command emacs gtermserver.py to illustrate backwards compatibility with the traditional terminal interface.

Showing the instructor “dashboard” in the virtual computer lab, with embedded views of student terminals.


Code tracing using online version of Python Tutor

https://github.com/mitotic/graphterm/raw/master/doc-images/gt-pytutor.png

Showing the screen for the command gtutor $GTERM_DIR/bin/pytutor/example-code/example.py | gframe -f, which displays an inline version of the Online Python Tutorial from pythontutor.com.


Collapsed mode

https://github.com/mitotic/graphterm/raw/master/doc-images/gt-screen-collapsed.png

Showing the screen when all command output is collapsed. Clicking on any of the underlined prompts will display the command output. Also note the Bottom menubar, which is enabled by clicking on the last prompt. Clicking on Control and then any of the prompts will cause the corresponding command to be pasted.


Split scrolling

https://github.com/mitotic/graphterm/raw/master/doc-images/gt-screen-split.png

Showing the split-screen scrolling mode, where the command line is anchored at the bottom of the screen. Clicking on gls output will paste filenames into the command line.


On the Raspberry Pi
