scancontext(TCL)


scancontext -- set scan file context

Synopsis

scancontext [option]

Description

This command manages file scan contexts. A scan context is a collection of regular expressions and commands to execute when that regular expression matches a line of the file. A context may also have a single default match, to be applied against lines that do not match any of the regular expressions. Multiple scan contexts may be defined and they may be reused on multiple files. A scan context is identified by a context handle. The scancontext command takes the following forms:

scancontext create
Creates a new scan context. The scanmatch command is used to define patterns in the context. A context handle is returned, which the Tcl programmer uses to refer to the newly created scan context in calls to the Tcl file scanning commands.

scancontext delete contexthandle
Deletes the scan context identified by contexthandle, and frees all of the match statements and compiled regular expressions associated with the specified context.
