Read variable from one file and save it to another

Read variable from one file and save it to another

Read variable from one file and save it to another

Hello everybody,

I found a very similar question on this site: http://www.tek-tips.com/viewthread.cfm?qid=1609656 but they were dealing with it in a manner that I couldn't quite use.

I am in a situation where I have 2 files: foo.tcl and bar.tcl. The problem I have is that I cannot edit "foo.tcl" but I need the contents of a variable in it (There is a provided proc that pauses code at the part I need). I "simply" need to copy the contents of a variable in "foo.tcl" to a variable in "bar.tcl"

Is there a way to do this beyond using the source command?


RE: Read variable from one file and save it to another

When you say that you "need the contents of a variable" from foo.tcl, does that mean that there is a "set varname value" statement in there somewhere?

If that's the case you can easily get it by opening foo.tcl as a text file and using a regexp to find it.

(in case that's what you're asking)
set fid [open foo.tcl r] for example:

CODE -->

set fid [open e:/ccs-c/dev/tcl/fixupl.tcl r] set s [read $fid] close $fid set m [regexp {(set dirStart)([^\n]*)} $s a b c]

now "c" has the value that the variable "dirStart" was set to.
