Wiki and shell#
Shell script/command is a bit like a wiki plugin. A console with history is a bit like a long web page. A wiki page could be a sequence of command, output. Or each command output goes in separate page and a session history shows the N latest subpages. Command line output has markup: return, tab, colors. A regular VT is needed to use VI or other fullscreen programs. I need more markup otherwise it's not worth the overhead of the webpage/wiki. Possibilities:
- recognise certain data forms, add markup (e.g. http, mailto, date)
- recognize command or wrap command with dedicated filter that adds markup
- allow new commands to add markup in their output
Ideas for markup#
- makes table a table
- add links to documentation
- add links that execute a command in the current shell)
- add image (e.g. Gnuplot output)
- add tag that tells JSPWiki to use a plugin (e.g. JfreeChart around some data).
- add menu of contextual actions
- add anchors that can be used to reuse output into new shell commands. Scenarios:
- click on prompt showing path, choose ls
- type lsof, output is decorated, pids show a menu of actions (pargs, stack, pwdx...)
- file prettifier annotates documentation with doc links etc.
- script displays information with local links and certain information as popups, linked pages
Bad scenarios#
- How to handle tail?
- ls -l on big directory is useless, big, pollutes search results, how to get rid of it?
- vi and other interactive programs don't mix well
Terminal Emulation in JavaScript#
Several terminal emulators are available which could be modified to enhance the text they display and or redirect it to web services.
<html>
<head>
<title>Anyterm</title>
<script type="text/javascript" src="anyterm.js">
</script>
<script type="text/javascript">
window.onload=function() {
create_term("term1","%h (Anyterm%v)",25,80,"","",50);
};
var on_close_goto_url = "";
</script>
<link rel="stylesheet" type="text/css" href="anyterm.css">
</head>
<body>
<div id="term1"></div>
</body>
</html>
The JavaScript terminal even handles applications like top nicely:
Writing to a wiki from the shell#
If we have FUSE and a filesystem view of the wiki then it's easy to write to a wiki from the shell. But one is not always root and some systems don't have fuse. So another idea would be to create a couple of commands that access a wiki and use environment variables.
Ideally curl would be used but authentication is not always easy. So it might be necessary to use a Java/XMLRPC API to acces the wikis:
