mkid TODO - Future directions

* Bring all code into conformance with GNU project coding standards.
  - Use command-line arguments, not the name of the program in argv[0]
    to determine lid's behavior
  - Use getopt_long () to parse command-line arguments.

* Portability
  - Fix filenames.c to handle non-UNIX file names properly.
  - Fix sizeof (int) == sizeof (long) assumptions.
  - The configure script tests for lots of things, but the code doesn't
    use all of the results that it should.

* lid
  - change the name of the program to something a bit more
    descriptive, e.g., "findid".
  - use "long long" (if the compiler supports it) integer comparisons
    in find_number().
  - generalize the command-line interface for different behaviors.
    User passes a command-format string for operating on the results
    of a query:
    %t = token, %f = crunched file list, %F = uncrunched file list
    Recommend the following aliases to emulate old behavior:
      alias lid="findid -e 'echo %t %f'"
      alias eid="findid -e 'vi +/\\<%t\\>/ %F'" # for vi users
      alias gid="findid -e 'egrep \\<%t\\> %F'"

* mkid & lid
  - store & retrieve floating point literals

* mkid
  - add a recursive file tree walker, so a complete list of file names
    need not be supplied.
  - Store attributes with symbols: type, func, variable struct-tag
    enum-tag, keyword, etc.  Store caller/callee relationships between
    identifiers.  Indicate which files have defns vs. uses.  This info
    is needed to support a cscope interface.

* cscope
  - add a cscope work-alike query interface (this is being done by
    Maureen Lecuona <lecuona@paul.rutgers.edu>)

* grep
  - Hack GNU grep to use a mkid database for hints about which files to
    search.
