concat variables in new lines

concat variables in new lines

(OP)
I'd like to concat some string-based variables and I want each of them in a new line. However, I can't find the correct way to write the code. This is what I tried:

CODE --> tcl

set mensaje "Error: esta atenuacion: $att dB\n"

gset listaMensajes  [concat [gget listaMensajes] "$mensaje"]

set mensaje "Error: esta atenuacion: $att dB\n"

gset listaMensajes  [concat [gget listaMensajes] "$mensaje"]

puts "[gget listaMensajes]" 

The variable $att takes different values in the different parts of the code.

I also tried:

CODE --> tcl

gset listaMensajes  [concat [gget listaMensajes] "\n" "$mensaje"] 

but none of them work; I get the messages in the same line sad

RE: concat variables in new lines

Hi

I think you may want

CODE --> Tcl

gset listaMensajes [concat [join [gget listaErroneos] "\n"] "\n" "$mensaje"] 
If listaErroneos is a list, concat just flatten it, not joins its items.

Sorry, it's the same list I want to concatenate!

CODE --> tcl

gset listaMensajes [concat [join [gget listaMensajes] "\n"] "\n" "$mensaje"] 

Anyway, I tried the code you wrote and it separates each word in the first puts and it shows it in one line in the second puts neutral

I found the solution:

CODE --> tcl

gset listaMensajes [join [list "[gget listaMensajes]" "$mensaje"] \n] 

peace
