sources-request@genrad.UUCP (06/12/85)
From: bene!luke!steven <Steven List @ Benetics Corporation>
The following shar contains two programs and their documentation:
cpg - a C source file formatter
mdep - a make dependency list generator
[ moderator's notes: cpg.c did not extract properly (I got 23652 rather
than the 23488 characters expected, yet it seems to compile fine.
Also, cpg uses getopt, and mdep does NOT use the directory library
routines, rather parses directories itself.
]
CPG is a little tool developed locally to enable us to produce listings
that had both line numbers and nesting level indication for our code.
My incentive was due to the lack of any such facility. Some of the code
in cpg is borrowed from cpr (came accross the net a while back), but
most of it is completely original. Those of you who have seen other
postings of mine, or see some more, will find that they include cpg
triggers throughout.
MDEP provides programatically what Larry Wall and others have done in
their makefiles (makedepend and make depend). It will search out and
list all include files needed to make a module. Hopefully, this will
find some legitimate use out there. We use it regularly here.
Please forgive the fact that these (and all my programs) are System III
specific. It's the only system that I have access to. If anyone out
there modifies them so that they are selectable (with ifdefs or
whatever) by version, please send them back to me.
Comments, improvements, and whatever are more than welcome.
Steven

X.SH NAME
Xcpg - C source listing formatter
X.SH SYNOPSIS
Xcpg [ -t tabstop ] [ file... ]
X.SH DESCRIPTION
X\*C is a C language source listing formatter. It employs certain
Xtriggers to perform its formatting. Those same triggers may be used to
Xextract in-line documentation to create documentation. At the end of
Xthe listing produced by \*C is a table of contents of all files and
Xfunctions contained in the current listing. The table of contents is
Xsorted alphabetically by function and file.
X.P
XThe listing produced by \*C includes on each line a line number. On each
Xline containing any braces ({}), there will also be a
Xnesting level indicator. The nesting level indicator includes a number
X(the current nesting level) and a directional character. The
Xdirectional characters are:
X.IP > 6
XThe nesting level increased on this line
X.IP < 6
XThe nesting level decreased on this line
X.IP * 6
XThe nesting level changed both ways, with a net change of zero
X.P
XThe triggers that \*C recognizes are itemized below. Each must appear
Xin column 1.
X.TP
X<formfeed>
XA formfeed will cause a new page to be started with a full header.
X.TP
X/*F filename *<anything>
XThe file name may be specified in a comment preceding a descriptive
Xheader block. The filename argument must be delimited by asterisks in
Xthe trigger. The filename will appear in all page headings up to the
Xnext filename trigger or the next file. A filename comment block
X\fBmust\fR be terminated by the endofblock trigger (see below).
XThis trigger will print as a line in the listing. This trigger causes
Xthe start of a new page (form feed) in the listing, with printing of the
Xpage header including the current file name.
X.TP
X/*H funcname *<anything>
XThe function name may be specified in a comment preceding a descriptive
Xheader block. The funcname argument must be delimited by asterisks in
Xthe trigger. The funcname will appear in all page headings up to the
Xnext funcname trigger or the next file. A funcname comment block
X\fBmust\fR be terminated by the endofblock trigger (see below).
XThis trigger will print as a line in the listing. This trigger causes
Xthe start of a new page (form feed) in the listing, with printing of the
Xpage header including the current function name.
X.TP
X/*E*/
XThis is the endofblock trigger. Everything between the last filename or
Xfuncname trigger and the endofblock trigger will be passed straight
Xthrough by \*C without evaluation of nesting levels, comments, or quoted
Xstrings. Thus, a header block is treated as one long comment by \*C.
XThis trigger will print as a line in the listing.
X.TP
X/*P*/
XThis is a page eject trigger. It will not print in the listing, but
Xwill be counted for line numbering purposes. This trigger causes the
Xpage heading, title, and subtitle to be reprinted based on their current
Xvalues (see title and subtitle below).
X.TP
X/*S <text> */
XThis is the subtitle trigger. It determines the contents of the second
Xtitle line on the page header. All characters after the initial space
Xand up to but not including the following asterisk (required) are
Xincluded as part of the subtitle. This trigger will not print in the
Xlisting but will be counted for line numbering purposes.
X.TP
X/*T <text> */
XThis is the title trigger. It determines the contents of the first
Xtitle line on the page header. All characters after the initial space
Xand up to but not including the following asterisk (required) are
Xincluded as part of the title. This trigger will not print in the
Xlisting but will be counted for line numbering purposes.
X.SS Options
X.IP "-t tabstop" 12
XThe tabstop argument to the -t option specifies how to expand tabs. The
Xexpansion is performed automatically with a tabstop of 8 if none is
Xspecified.
X.SS Arguments
X.IP file 12
XAny number of file names may be specified on the command line (within
Xlimits set by whichever shell is used). Each file will be formatted and
Xits name added to the table of contents. If no file names are
Xspecified, \*C will read the standard input.
X.SH FILES
X.IP "/tmp/toc_XXXXXX" 20
Xtemporary file for building the table of contents.
X.SH "SEE ALSO"
Xdtab(1), nl(1), pr(1), sort(1)
X.SH NOTES
XThis tool was developed at Benetics Corporation.
X.P
XA side note: \*C also properly processes comments in shell scripts and
Xmakefiles. These comments are correctly handled when the comment
Xcharacter (# or :) is the first nonblank character on a line. In order
Xto facilitate documentation of shell scripts, \*C recognizes the
Xsequences #{ and #} as the beginning and ending of nesting, and treats
Xthem as it does in C program sources. Thus lengthy for, if, while, and
Xcase statements may be more clearly documented as to nesting levels,
Xparticulary in shell scripts.

X.SH NAME
Xmdep - generate the dependency list for C sources
X.SH SYNOPSIS
Xmdep [ -D symbol ] [ -I searchpath ] [ -r ] [ -x \fIabc\fR ]
X.br
X sourcefiles
X.SH DESCRIPTION
XThe purpose of \fImdep\fR is to generate the list of include file
Xdependencies for some source file. The source files are expected to be
XC language source files, and may include either .c or .h files (or any
Xother file, for that matter). The source files are examined for lines
Xcontaining the `#include' statement (also `$include' for those of us who
Xuse UNIFY), and those file names are included in the list of dependencies.
X.P
XAdditional features are provided by command line options: recursive
Xexpansion of include files (includes that include includes), suppression
Xof expansion of specific include files, and Defining symbols so that the
Xappropriate dependencies are generated.
X.SS Options
X.IP "-D symbol" 16
XDefine a symbol (as you would to the C preprocessor) to cause the
Xrecognition of the appropriate sections of code. Since \fImdep\fR does
Xnot read #define statements in the source files, this is the only way of
Xcausing symbols to be defined. Conversely, symbols are #undef by
Xdefault. Multiple occurrences of the -D option, with argument, may
Xappear in the command line.
X.IP "-I searchpath" 16
XDefine a directory to be searched for include files, as is done for the
XC preprocessor. Multiple occurrences of the -I option, with argument,
Xmay appear in the command line.
X.IP "-r" 16
XPerform recursive expansion of include files. Thus, if an include file
Xincludes other files, include those file names (and so on) in the
Xdependency list. This option is moderated by the -x option.
X.IP "-x filename" 16
XExclude a file from recursive expansion. The filename associated with
Xthis option may omit the .h suffix, and \fImdep\fR will append the
Xsuffix.
X.SS Arguments
X.IP sourcefile 16
XOne or more C source files to be processed. The files may actually be
Xany ascii file.
X.SH EXAMPLES
XThe following example shows the command to process mdep.c and the output
Xfrom the command:
X.nf
X.RS 6
X.P
X% mdep -r mdep.c
X.sp
Xmdep.o: \\
X /usr/include/sys/types.h \\
X /usr/include/sys/dir.h \\
X /usr/include/stdio.h
X.RE
X.fi
X.P
XTo generate the dependency list for file `foo.c' that includes `foo.h'
Xwhich includes some standard files:
X.nf
X.RS 6
X.P
X% mdep -r -I/usr/local/include foo.c
X.sp
Xfoo.o: \\
X ./foo.h \\
X /usr/include/stdio.h
