wkterm

wkterm is a Webkit Terminal. It's built with webkit-gtk, so it runs in linux. But the host application is very simple, so it can rather easily be ported to Mac.

In difference with TermKit (which this project was inspired by), wkterm is real terminal emulator and it does aim to host 'vim', mc, top or emacs or anything else. Also, which is in fact the main purpose of the project, wkterm have graphical features (such as inline image viewing - see imgcat source). Graphical features are implemented by using custom escape sequences. There's another possibility also to recognize file format on the fly (that's, when we see jpeg bitmap header, we treat it as bitmap, when we see video, we show video player).

CPU usage. It's possible to run both utilities on the remote machine (that is on the screenshot), or run gen_cpu on the remote and run wktgraph locally (like, "(ssh shepik@thiamis ./gen_cpu ) | ./wktgraph" ) gen_cpu is a simple utility which just prints out current cpu usage, one value in one line each half a second. You can run it in regular console, too.

Current todo:

1. (almost done) Proper keyboard handling. I press any non-character key (like arrow-up, or F1, or Ctrl+C, or Esc), esc-sequence should be sent. http://sunsite.ualberta.ca/Documentation/Gnu/screen-3.9.4/html_chapter/screen_11.html#SEC60 https://github.com/pnitsch/jsTerm http://anyterm.org/download/index.html

2. (done) Cursor.

3. Paste. Copy already works 'cause it's handled by webkit.

4. (done) ANSI Colors.

5. (done) Window resize handling - pseudoterminal's (pty) attributes should be set according to window size, so js have to calculate size of the window in characters and send this info to C part.

6. Proper line mixing: there are image lines mixed with usual terminal text lines, and if we run a full-screen application like mc, what should happen? What should happen to images?

7. More escape sequences support. So that vi and mc would work. http://invisible-island.net/xterm/ctlseqs/ctlseqs.html#VT100%20Mode http://euc.jp/i18n/ctlseqs.txt http://www.mit.edu/afs/athena/system/x11r4/src/mit/clients/xterm/ctlseq2.txt http://sunsite.ualberta.ca/Documentation/Gnu/screen-3.9.4/html_chapter/screen_11.html

8. DEC Special Character and Line Drawing Set support

Ideas of usefull applications:

1. wktcat - show image
2. wktls - show list of files with thumbnails
3. wkttable - that's for 'mysql -e "SELECT * FROM table" | ./wttable' and other types of text-to-real table conversions
4. wktgraph - draw simple charts in realtime. cpu usage, requests per second, average response time..
5. ... ?
