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 com-
mand 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
}
