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 restric-
tion 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".
A leading BOM (Byte order mark) contained in the file is ignored for
unicode encodings (utf-8, unicode).
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
}
