source(n) Tcl Built-In Commands source(n) 





NAME


source - Evaluate a file or resource as a Tcl script






SYNOPSIS


source fileName


source -encoding encodingName fileName








DESCRIPTION


This command takes the contents of the specified file or resource
    and passes it to the Tcl interpreter as a text script. The return value from
    source is the return value of the last command executed in the
    script. If an error occurs in evaluating the contents of the script then the
    source command will return that error. If a return command is
    invoked from within the script then the remainder of the file will be
    skipped and the source command will return normally with the result
    from the return command.


The end-of-file character for files is “\32” (^Z)
    for all platforms. The source command will read files up to this character.
    This restriction does not exist for the read or gets commands,
    allowing for files containing code and data segments (scripted documents).
    If you require a “^Z” in code for string comparison, you can
    use “\032” or “\u001a”, which will be safely
    substituted by the Tcl interpreter into “^Z”.


The -encoding option is used to specify the encoding of the
    data stored in fileName. When the -encoding option is omitted,
    the system encoding is assumed.






EXAMPLE


Run the script in the file foo.tcl and then the script in
    the file bar.tcl:




source foo.tcl
source bar.tcl



Alternatively:



foreach scriptFile {foo.tcl bar.tcl} {


   source $scriptFile
}
