source(n)

sourcen

Evaluate a file or resource as a tcl script

Usage

source fileName

source -encoding encodingName fileName

Overview

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 (^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 in code for string comparison, you can use or which will be safely substituted by the Tcl interpreter into

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.

Examples

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 }
