Tpett

Tpett - Tcl Proc Evaluator/Timer/Tester

Directions to find it at Stu

Stu - 2007/10/18 Created this page. As a testament to Tcl and this Wiki, this program took about a day to write initially and a few more hours to finish off a quickie 0.1 version. Pretty good since I hadn't done any gui programming in quite some time (years?) and had never really used a canvas. Getting the gui to grid properly took maybe 20% of the time - grrr.


From the help:

"Tpett is for to test and graph Tcl proc performance, allowing for simple proc performance comparisons."

The distribution files contain the source and some examples but for you masochistic types, here's the source code (some of it is not pretty, especially the graphing code which is not quite right in the head. You've been warned):

 $cfg(prog) is for to test and graph Tcl proc performance,
 allowing for simple proc performance comparisons.
 
 Put procs to test in "To Test". Click "Eval".
 Put test code in "Run Test". Click "Eval".
 
 When "To Test" code is evaluated, $cfg(prog) will automatically accumulate procs.
 Accumulated procs will show in "Procs" listbox on right.
 Double click on a proc in "Procs" listbox to select or deselect it for testing.
 
 To test, the command \[test\] must be called with the following parameters:
 procname:  Name of proc to test.
 argument:  Argument to proc. Only one argument possible now. Maybe more later.
 testpoint: Value of testpoint; ex: \[string length \$inputData\].
 times:     How many times (as in the \[time\] command) to run the proc. Optional; default: 1.
 
 The command \[getprocs\] will return a list of selected accumulated procs,
 
 The command \[title\] will set the title of the graph; ex: title "String Command Tests".
 
 The command \[xaxistitle\] will set the title of the x-axis of the graph;
 ex: xaxistitle "Input String Size".
 
 Check or uncheck "Smooth" for desired smoothiness.
 
 Click "Exit" button or press "Esc" key to exit program.
 Unplugging computer will also work.
 
 Click one of the "Load" buttons to enable loading of program data file information
 from rigid spinning disk platter, solid state storage, magnetic drum, conga drum,
 abacus, usb-connected windchimes or extraterrestrial transmission.
 
 Click "Example" button or run without args to get example usage.
 
 Run from command line:
 \$ ./tpett.tcl totest.tcl runtest.tcl
