Richard Suchenwirth 2002-07-21 - I needed such a little tool at work, and thought that other Tclers could use it too. Basically it is a small UI wrapper for searching a text file (like a no-frills grep). Specify your search term in the entry above, hit <Return>, and see in the text which lines from the file given at startup matched. For convenience, case is ignored (one might make this switchable); the entry is cleared on cursor <Up>; and the number of matching lines is displayed in the end.
Currently I don't need it, but with a few lines more, encoding configuration (e.g. for Chinese or Korean) could be built in... Only, typing the search term would require a little input manager (as in taiku goes multilingual).
