- scancontext [option]
- 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
- Create a new scan context. The scanmatch command is
- used to define patterns in the context. A
- contexthandle 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
- Delete the scan context identified by contexthandle,
- and free all of the match statements and compiled
- regular expressions associated with the specified
- context.
