- - Xref Version 3.1 - HISTORY.DOC -
-
-
- Changes and updates:
-
- Version 2.01
-
- o Did some tweaking, and reduced the program size about
- 35% and increased execution speed about 15%.
-
- o Fixed a small bug in the function tree output. Also,
- function names are now output in the order they are
- referenced in the function.
-
- Version 3.0
-
- o Fixed a small bug that sometimes tagged a global
- variable's type in a function listing as being
- "unknown" when it really wasn't.
-
- o C xref now looks for the "res_word.txt" file in the
- same directory it is run from. Before it looked in the
- default directory.
-
- o Removed the limit on the number of include files deep
- that C xref will open. It will now open files until the
- system runs out of handles, at which time it tells you
- that it is unable to open the file.
-
- o Improved (at least I think so) the output of the local
- and global variables in the "function" section. Got rid
- of the module name where a global variable originates
- (I didn't think that it was really necessary here), and
- made the line numbers for the local variables line-up
- like the global variables do.
-
- o Improved the "function tree" output section by making
- it put a blank line between function calls that fall
- directly below each other in the same column.
-
- o C xref can now cross-reference many more modules at one
- time. C xref creates a temporary file in the directory
- that C xref is run from, and saves most of the
- function's information in it, which frees a lot of
- memory. (I cross-reference over 1/2 meg. of source code
- without running out of memory.) If you still run out of
- memory, and you are cross- referencing header files,
- try it without the headers (header files make a lot of
- global declarations, which are kept in memory and are
- not saved to the temporary file. This can use a lot of
- memory).
-
- o Struct variables are now labeled with their tag type,
- when possible, instead of [struct].

- - Xref Version 3.1 - HISTORY.DOC -
-
-
- o The only C++ compatiblity enabled at this time is that
- C++ keywords and comments (i.e. "//") are ignored. C++
- compatiblity will be added in a future update.
-
- o The RES_WORD.TXT file has been updated to include all
- ansi C and C++ key words.
-
- o If a function name is over 20 characters long, then it
- is truncated when it is output in the "CALLS" section
- of the "FUNCTION" report. When this occures, the
- truncated name will be followed with three elispses.
- [i.e. {filename.c}Very_very_long_na...()]
-
- o You can now format the output in the verbose function
- listing with the '-f' command. The command recognizes
- C's standard formatting commands, '\f' and '\n'. A
- space must separate the command and the format string,
- and no spaces should appear in the formatting string.
- For example: -f \n\n\n This command would output
- three newlines after each function's cross- reference.
-
- Version 3.0a
-
- o A list of a function's input parameters is now included
- in the verbose cross-reference listing. It follows the
- "CALLS" section.
-
- o Functions that have no line of origin are no longer
- referenced in the verbose listing or the function tree
- output. (They continue to be referenced in the function
- summary, however.)
-
- o The wild card character "*" can now be used in the
- RES_WORD.TXT file. Operates the same as with DOS
- filenames.

-
-
- Version 3.1
-
- o If a header file command line included a path name
- (i.e. #include "c:\text\myheader.h") C xref ignored it.
- Fixed that. C xref will now use the path if given.
-
- o In the same vein, added a new command (-p
- path;path;...) that lets you input alternate search
- paths. These paths will be searched when looking for C
- modules and header files.
-
- o Eliminated the "P" (path names) command that follows
- the "-i" command. No longer needed because of above.
-
- o Added the "-o" command. This command allows you to
- output in the verbose and tree sections those functions
- that have no line-of-origin.
-
- o To save memory (and loading time) when not cross-
- referencing Windows' programs I split the RES_WORD file
- into a C file (RES_WORD.TXT) and a "Windows" file
- (WIN_RES.TXT). The WIN_RES file is only loaded when the
- "-m" command is entered (the RES_WORD file is always
- loaded). The "-m" command also improves the tree output
- for Windows' programs. The calling hierarchy is output
- for the "WinMain" procedure and for any procedure
- name(s) that are assigned to a WNDCLASS structure (i.e.
- wndcls.lpfnWndProc = WindowProc).
-
- o Changed the program's name to "Xref," because I
- discovered that there is another cross-reference
- program that uses the name "C xref."
