Split question

[Jboy123]

Hi All

Aplogies in advance for a dumb question.

I'm trying to read in a file format as follows:

myVariableName=myValue

I then do a split against this:
set props [ split $arg = ]

Then I assign assign values to my variables:
set [lindex $props 0] [lindex $props 1]

That's all fine until my file contains something like:

myvariableName=myValue=1234

Of course the split discards the last value. I want to keep the value as "myValue=1234"

Is there a split option to tell it to split only on the first occurrence of the = ??

Or - a better way to fo this?

Many thanks in advance
Jules

Since you know that you only want to split what comes before and after the first "=" you could do something like this.

set props [ split $arg = ]
set first_element [lindex $props 0]
set second element [lrange $props 1 end]



The lrange command is useful in these situations. It allows you to grab multiple parts of the list at a time. Since you arent sure of where your last element is you may use "end".

That's a big help!
