|
|
An "ID database" is a binary file containing a list of file
|
|
names, a list of tokens, and a sparse matrix indicating which
|
|
tokens appear in which files.
|
|
|
|
With this database and some tools to query it, many
|
|
text-searching tasks become simpler and faster. For example,
|
|
you can list all files that reference a particular `\#include'
|
|
file throughout a huge source hierarchy, search for all the
|
|
memos containing references to a project, or automatically
|
|
invoke an editor on all files containing references to some
|
|
function or variable. Anyone with a large software project to
|
|
maintain, or a large set of text files to organize, can benefit
|
|
from the ID utilities.
|
|
|
|
Although the name `ID' is short for `identifier', the ID
|
|
utilities handle more than just identifiers; they also treat
|
|
other kinds of tokens, most notably numeric constants, and the
|
|
contents of certain character strings.
