lx example

lx example

This is a simplish example for the use of lx. It is much smaller than the lxt application, so it is easier to see how it works and how lx is used.

The example program generates a kwic (key word in context) listing for a text. It optionally allows a stop list and a word-form list to be run against the text.

Here is the program source. The program is included with the lx source, and can be compiled from the lx src directory by typing "make kwic" (after running "./Configure").

The usage is:
kwic [-s stoplist] [-f formslist] inputfile

Output (to standard out) looks like:
