# TITLE: Intel Bind (Link) Configuration file object file extractor
# DATE: 09/20/1989;
# VERSION: 1.8;
# DESCRIPTION: "An AWK program which scans a bind-configuration
# file and builds a batch file which will in turn
# produce a make-file. Requires the services of a
# source-file dependency generator (such as cincdep)."
# KEYWORDS: Makefile, make, include, dependency generator;
# SYSTEM: MS-DOS;
# WARNINGS: "Your CF file must contain all of the object files which
# you want scanned. PolyAwk will generate false matches
# to lines beginning with non-ASCII (i.e. 128..256) chars."
# FILENAME: CF2MAK.AWK;
# SEE-ALSO: CINCDEP.AWK, TLR2MAK.AWK, AINCDEP.AWK, PINCDEP.AWK;
# AUTHORS: James Yehle;
# COMPILERS: PolyAWK, Mortice Kern AWK, Rob Duff's PC-AWK 2.0;

#
# Scans an Intel bind configuration file to produce a batch file
# which will call dependency generator(s) to build a set of
# make-file dependency lists, and eventually a full make-file.

# . . . Revision history . . . . . . . . . . . . . . . . . . . . . . . . . . .
#
# 1.8 Sep 19 89 JRY Added target-file, i.e. "object(name)", name
# extractor.. uses iRMX default if absent.
# 1.7 Sep 10 89 JRY Added legal-filename-char regular expression
# 1.6 Aug 28 89 JRY Added "verbose" CO output as debug level 1.
# 1.5 Jul 24 89 JRY Removed source & include pathnames from command-
# line (it was getting too long for in DOS) and
# made them into internal variables. Added ASM
# and PL/M source/include pathnames (which defi-
# nitely wouldn't have fit onto the command line),
# along with code to call those two languages'
# dependency generators. Expanded "cc" & "ccf"
# to support multiple languages, not just C.
# removed them from command-line as well.
# 1.4 Jun 20 89 JRY Added "lcf=" and "ccf=" command-line parameters
# 1.3 Jun 7 89 JRY Added "incpath=", "cc=" & "cl=" command-line
# parameters (and get_cl_param() to handle 'em)
# 1.2 May 30 89 JRY Added "srcpath=" command-line parameter,
# added executable-file dependency list to top
# of depencency-file (outfile)
# 1.1 Cinco di Mayo 89 JRY Closed file after checking if it exists
# 1.0 Apr 21 89 JRY Initial creation

#
# Usage is:
# awk -f cf2mak.awk filename.cf outfile=[path]filename
# lc=command lcf=[p][n][e] [>batchfile]
# where outfile gets the conglomerated dependency generators' output
# Order of command-line parameters (save for "-f ..."
# and ">batchfile") is irrelevant, but identifiers must be in lower case.
# lc is the compile command (no spaces allowed)
# lcf controls which components of the source file's name get
# included in the link command line: p = directory path,
# n = name, e = extension.
# . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
#
# Takes an Intel bind configuration file as input.
# Generates an executable-dependency list at the start of outfile,
# followed by the link command and the primary (executable) file name.
# Extracts all "filename.obj" file names.
# Generates a batch file line, for each object file found, of the form:
# comdpre srcfile "incpath="incpath "objname="file.obj
# "cc="cc "ccf="ccf comdmid outfile comdpost
# unless the source file can't be found, in which case it makes this batch file line:
# comdpre "__NOFILE__ objname="file.obj "cc= ccf= " comdmid outfile comdpost
# The search for the source file covers C, assembly, and PL/M path and extensions.

BEGIN {
# Set various strings used in building batch-file command lines
# Cf2mak supports several languages. Each language must have
# 1) a source file name extension (to replace ".obj" in searches)
# 2) a source directory pathname (stuck on front of file name during search)
# 3) an include-file directory whose name to pass to a dependency scanner
# 4) a compiler command to pass to dependency scanner (no spaces allowed)
# 5) controls for filename pathname/extension inclusion in compile command line
# 6) a dependency generator awk program
