Hello Aia, and thanks for the response.

I'm interested in learning the ins and outs of regular expressions for the purpose of crossword and other word puzzle writing.

Typically with crossword writing, the basic grep commands are more than sufficient for any needs that I might have.

But lately I'm developing some new types of word puzzles, and I'm trying to perform some search operations which are difficult but I believe may be possible in Unix. I suspect a Perl script could be written to do what I need, but I don't know enough about it to be sure about that either.

I started a thread some time ago that discussed the actual problem. Received some very thoughtful feedback and some code that seemed promising, but it became complicated so quickly that I couldn't follow. I realized I would have to learn a lot more just to understand the approaches and solutions that people were sending me. So I figure a few hours with a face-to-face meeting would be helpful.

Regular Expressions

what elements does " /^/ " match? I did the test which indicates that it matches single lowercase character like 'a','b' etc. and '1','2' etc. But I really confused with that. Because, "/^abc/" matches strings like "abcedf" or "abcddddee". So, what does caret ^ really mean? Any response... (2 Replies)

GENLIB_COPY_UP_ALL_CON.3(October 1, 1997)								 GENLIB_COPY_UP_ALL_CON.3(October 1, 1997)

NAME
GENLIB_COPY_UP_ALL_CON - copy all physical connectors of an instance face in the current figure SYNOPSYS
#include <genlib.h> void GENLIB_COPY_UP_ALL_CON(face, insname, concatenate) char face, concatenate; char *insname; ORIGIN
This software belongs to the ALLIANCE CAD SYSTEM developed by the ASIM team at LIP6 laboratory of Universite Pierre et Marie CURIE, in Paris, France. Web : http://asim.lip6.fr/recherche/alliance/ E-mail : alliance-users@asim.lip6.fr PARAMETERS
face Face of the instance insname Name of the instance the connector belongs to concatenate Indicates wheter or not to concatenate instance connectors names with instance name DESCRIPTION
COPY_UP_ALL_CON copies all instance connectors of the face face of the placed instance called insname into the current layout. The con- catenate argument may take two values: YES then the resulting name of a connector in the current figure is the concatenation of the insname and the conname. It warranties the unicity of name at the figure level, and is to be used most of the time. NO implies a direct copy of the connector name. The user must take care of the unicity of connector name by itself. Two behaviour are expected, depending on each of the instance connectors location regarding the abutment box of the current figure. Connector on the abutment box The figure connector is place right over the instance connector. The single connector is duplicated. Connector inside the abutment box The instance connector face is computed in the figure, and then, the connector is duplicated on the given face, at the right coordinates for this face. Then a wire is drawn between the instance connector and the figure connector in the connector layer. ERRORS
"GENLIB_COPY_UP_ALL_CON impossible : missing GENLIB_DEF_PHFIG" No figure has been yet specified by a call to DEF_PHFIG. So it isn't possible to place a connector inside it. you must call DEF_PHFIG before any other layout action. "*** genlib error *** GENLIB_COPY_UP_ALL_CON impossible : connector conname face face of instance insname, current figure doesn't exist" No connector matches both the conname and the face arguments. EXAMPLE
#include <genlib.h> main() { /* Create a figure to work on */ GENLIB_DEF_PHFIG("cell"); . . GENLIB_PLACE_LEFT("gaer0_f", "insN", SYMXY); . . GENLIB_DEF_AB(0L, 0L, 0L, 0L); /* Copy all connectors */ GENLIB_COPY_UP_ALL_CON(NORTH, "insN", YES); /* Save that on disk */ GENLIB_SAVE_PHFIG(); } SEE ALSO
