YGrep Search Engine v6.05 5th may 1998 (C) Yves Roumazeilles 컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴컴� The YGrep Search Engine is a text search library to be used with any kind of Windows application. It has two possibilities: - approximative search based on Baeza-Yates algorithm to find a pattern which is only partly known (also known as search with erroneous patterns). For example, you can search for "pattern" with 1 error (at most) and it will match "pattern", "pittern" and "Pattern" while stepping over "lantern" (2 errors) or "paattern" (insertions are not errors). - search modelled on the Unix utility named GREP. It is particularly useful for complex searching with the help of its specific search "language" to describe the pattern you look for. For example, you can search for "^pattern" to look for "pattern" at the beginning of a line; or for "[pl]a[nt]tern" to look for either "pattern" or "lantern". Look into the Help file for an extensive description of the pattern language. - soundex-based search where text is matched against patterns following a presupposed law helping in recognizing very poorly written english words (more simply put: by collapsing similar sounds into common sonorities). They are particularly useful to improve greatly the search capability of an existing tool such as a text editor, a data base search engine, etc. As a whole, the YGrep Search Engine contains nice things like: - powerful search and substitute functions for C/C++ programmers - their simpler and more usable counter-parts for FoxPro, Visual Basic users. - file operations for immediate application - combined search operation (boolean operators) for the power user/programmer - optional error messages/dialog-boxes for high-end applications - free bonus YFind search application (similar to grep(1) from Unix) - interface for such languages as Visual Basic, Delphi 2.0, Borland and Microsoft C/C++ compilers, etc. The Windows help file gives detailed on-line information about using it. It is complemented by the printed reference manual the registered user will receive. Minimal File List: YGREP32.DLL Basic DLL (for 32-bits package only) YGREP.HLP Help for programmer (function description) YGREP.TXT This file YGREP.H For C programmers BITLIST.H YGREPINT.PAS For Delphi programmers YGREP32.BAS For Visual Basic programmers YGREP.LIB Interface file for Visual C++ YGREPB.DEF Application definition file for other environments CLUSTER.TXT Description of the ClusterView Windows application BITLIST.TXT Description of the BitList Engine ORDER.TXT Minimal order form To install The YGrep Search Engine, simply put the files YGREP32.DLL and YGREP.HLP in any directory already included in your path (C:\WINDOWS suggested). If you already have an earlier version of the YGrep Search Engine, replace its old YGREP.DLL file by the new one. Place YGREP.H, and BITLIST.H in your include file directory (see your compiler documentation) and YGREP.LIB in your library directory (see your compiler/linker documentation). If Windows cannot find the DLL when the application is run, make sure it is in a directory on your path, and try again. Borland users could profit from looking into the file BORLAND.TXT. The YGrep Search Engine is shareware. It it not Public Domain or Free. See the help file for shareware information and extensive description of the registration steps (including a number of registration sites accepting 800-calls or credit cards). If you cannot find the Help file and its registration forms, use the minimal form file ORDER.DOC and mail it with your payment to the address shown. If you find the YGrep Search Engine useful, do the decent thing and register! In return you will receive (for a Single User license): - the full YGrep Search Engine (in its latest version), with Windows 32-bit libraries, - the reference and user manuals (15000+ words of advice, examples, and information) in Adobe PDF files, - source code of the help files which can be modified to build your own application help file, - source code for some useful resources that can be included in your own application, - source code for our test program, - Visual Basic and Delphi header files, - a registration number to identify yourself, - support thru Email, phone and Fax. When you register the full Developer Kit, you will ADDITIONALLY receive: - an **UNLIMITED NUMBER** of target licenses, - the printed reference and user manuals (15000+ words of advice, examples, and information), - complete **SOURCE** code of the library, which will allow porting to other Operating Systems (including MS-DOS which already is in the Makefiles) - Makefiles for Visual C++ 4.xx, Borland C++ 4.xx, etc. - complete **SOURCE** code of the YFind application (including a public domain version of GETOPT.C), the best demonstration/sample for the file-based functions, - free automatic access to all the future minor releases of the library including all bug removal, - and a 20% reduction on the registration fee for the major releases.
