For 2021 - online Python 3 training - see ((here)).

Our plans were to retire in summer 2020 and see the world, but Coronavirus has lead us into a lot of lockdown programming in Python 3 and PHP 7.
We can now offer tailored online training - small groups, real tutors - works really well for groups of 4 to 14 delegates. Anywhere in the world; course language English.

Please ask about private 'maintenance' training for Python 2, Tcl, Perl, PHP, Lua, etc.
Output to stdout: hidden in Komodo 3.0 ?

Posted by Dimon (Dimon), 6 March 2006
My application combines a several command-line utilities in one large test program system. I calling one part of them with 'exec' command and another part of them is runned  in a separate pipes. But I found that a command-line utility with a long working time don't  show me the output in stdout in real time: the output data is printed into console only after the work of command-line utility is over. I try to flush a buffer, try to configuring an output channel with 'configure' command with -buffering option but all actions were effectless. When the spawned program must to read something from stdin, the user who executed this script don't see an input prompt: it still hidden.

Then, I try to use a simple commmand construction:
Code:
eval exec MPMPrg >@stdout 2>@stderr <@stdin

where MPMPrg is a command line utility name.

Yes! A command line utility start to output it's data into tclsh console. But when I continue to debugging Tcl-script with Komodo 3.0 Pro, I still see nothing and cannot interact with command-line utility   .
Is the anybody Komodo experts with any ideas about this problem?  

And a second question about Komodo: when I debug the script with Komodo, if script requires to input any string data and save it into any variable, the variable not setted! I bound to press a 'pause' button, input the value, press an 'Enter' key and after that set a variable value manually   In tclsh console the same works correctly.
Any ideas to solve this problem?

OS: Win2K Pro SP4.
Tcl interpreter: 8.4.2 with threads support.
Tcl Debugger: Komodo 3.0 Pro.

Dimon, you always come up with such excellent (and specific and advanced) questions.   I've left this one uncommented on so far as I don't use Komodo so wouldn't know, and I was just wondering if others might.   You might reach people who know this particular niche if you look at / ask on ActiveState's support services as Komodo's theirs.
