opmhash \- Hasher for summary keywords in Eclipse files
|
|
.SH DESCRIPTION
|
|
opmhash: invalid option \fB\-\-\fR 'h'
|
|
The purpose of the opmhash program is to load a deck and create a summary, by
|
|
diffing two such summaries it is simple to determine if two decks are similar.
|
|
For each keyword a hash of the normalized content is calculated. The output of
|
|
the program will look like this:

Where the 'random' integer following each keyword is the hash of the content of
|
|
that keyword. The hashing is insensitive to changes in white\-space and comments
|
|
and file location. At the bottom comes a total hash of the complete content. The
|
|
hash of each keyword is insensitive to shuffling of keywords, but the total hash
|
|
depends on the keyword order.

.SH OPTIONS

.HP
|
|
\fB\-l\fR : Add filename and linenumber information to each keyword.
|
|
.HP
|
|
\fB\-s\fR : Short form \- only print the hash of the complete deck.
|
|
.HP

.PP
|
|
It is possible to add multiple deck arguments, they are then scanned repeatedly,
|
|
and the decks are compared. In the case of multiple deck arguments the exit
|
|
status of the program will be zero if all are equal and nonzero in case of
|
|
differences.
