* module/ice-9/source-properties.scm: New file, providing the source-properties API, as well as a replacement for `read' that always attaches source properties, regardless of the 'positions option on the port. * am/bootstrap.am (SOURCES): Add the new file. * libguile/srcprop.c: * libguile/srcprop.h: Remove. * libguile/Makefile.am (libguile_@GUILE_EFFECTIVE_VERSION@_la_SOURCES): (DOT_X_FILES): (DOT_DOC_FILES): (modinclude_HEADERS): * libguile.h: Remove srcprop.h. * libguile/deprecated.c: * libguile/deprecated.h: Add deprecation shims for srcprop.h interface. * libguile/backtrace.c: * libguile/debug.c: * libguile/eval.c: * libguile/init.c: * libguile/memoize.c: * libguile/promises.c: * libguile/read.c: * libguile/syntax.c: Remove needless srcprop.h includes. * module/ice-9/boot-9.scm: Reorder some definitions so that deprecated modules can use the (system syntax internal) module. * module/ice-9/deprecated.scm: Add shims for Scheme source-properties interface. * module/ice-9/read.scm (read): Never attach source properties. Users that want source can use read-syntax. * module/language/cps.scm: * module/language/cps/spec.scm: * module/language/ecmascript/compile-tree-il.scm: * module/language/elisp/compile-tree-il.scm: * module/language/elisp/lexer.scm: * module/language/elisp/parser.scm: * module/language/tree-il.scm: * module/language/tree-il/spec.scm: * module/language/wisp.scm: * module/system/base/lalr.scm: * test-suite/tests/elisp-reader.test: * test-suite/tests/reader.test: * test-suite/tests/srcprop.test: * test-suite/tests/srfi-105.test: * test-suite/tests/srfi-119.test: Use the (ice-9 source-properties) module to get access to source properties.
