moodss (Modular Object Oriented Dynamic SpreadSheet) is implemented in the great Tcl language (requires at least versions 8.0 of Tcl and Tk, for UNIX or Windows).

Moodss is a modular application. It displays data described and updated in one or more independent modules loaded when the application is started. Data is originally displayed in tables. Graphical views (graph, bar or pie charts) can be created from any number of table cells through a simple drag'n'drop operation. Table rows can be sorted in increasing or decreasing order by selecting any column.

Since module data access is entirely customizable (through C code, Tcl, HTTP, ...) and since several modules can be loaded at once, applications for moodss become limitless. For example, comparing a remote database server CPU load and a network load from a probe on the same graph becomes possible.

Apart from a sample module with random data, ps, cpustats and memstats modules for Linux are included as examples (running "wish moodss ps cpustats memstats" mimics the "top" application with a graphic edge). Module contibutions are of course welcomed and will be included in my home page.

Thorough help is provided through menus, widget tips, a message area, a module help window and a global help window with a complete HTML documentation.

One or more module names are passed as command line parameters. The moodss core then loads the modules and starts displaying their data in one or more tables, which are then updated at a user selectable frequency.

The module code is the link between the moodss core and the data to be displayed. All the specific code is kept in the module package. Moodss goal is to become a complete and generic way of monitoring data.

Development of moodss is continuing and as more features are added in future versions, backward module code compatibility will be maintained.

User Comments:

  • It's not exactly a spreadsheet in the typical sense; there's no cell references like A1 or B15 (or even r1c5) or formulas. It seems that one has to writes modules for it to be useful. (anonymous)
