Hello,

it is compiled code, it's a text format but we cannot read

purpose of tbc is to hide source code of some authors

But in some case we can dump it back, for example if the codes were written in body of namespace or the codes is a part of a class (object-orient)

otherwise just the guys wrote tbcload and procomp know how to read tbc

yes code is written in namespace body.

 

can i convert the '.tbc' code in standard '.tcl' format?

 

 

thanks

yes, you can get tcl codes of each compiled procedure by using

info args procname

info body procname

Hello

as i know there is no available tool to convert tbc file to tcl file

above guide just help you to be able to know what the tbc file do by dumping its detail actions

 

to dump a procedure explicitly,  open command window and type in:

dump procname

 

if the procedure was pre-compiled, then nothing resulted

it (procedure) can be dumped if it is inside a namespace, an object or nested in a command (generated from a command)

Hello Tinh,

 

Do you know which free/opensource software to convert from *.tcl to *.tbc?

tinh

I am sorry because I don't know such a software.

But I can debug it to know how it acts. Because it will invoke other tcl commands, by tracing them we may know what's happening.

unfortunately, this is a terrible work, with tons of output need to be parsed

Hi Tĩnh.

 

I am sorry for making wrong explanation. I would like to know how to compile my tcl code to *.tbc in case I wanna protect my program.

Hi alpha,

I use this soft:

https://www.tcl.tk/software/tclpro/eval/1.4.html

newer versions are released by active-state

this v1.4 cannot compile newer syntax like {*}, expr with eq, ne, in, ni operators,...

Thanks Tinh so much for your information!

I have tried this way but I haven't got the body if code instead it is throwing me an error saying 'compiled -- no source code available'

 

Is there any other turnaround ?

Compiled script cannot be dumped by that way

Commands inside body of switch, [ ] ,... are exposed and can be traced, but no way to trace commands in level 1 of a proc because they are converted to bytecode

Before, you can buy TclDevKit at ActiveState. But it's not possible from now.

In fact ActiveState have released TDK as OpenSource software: https://www.activestate.com/blog/tcl-dev-kit-now-open-source/
