From c71b79a13a7960f255e6e1d66ca543daba328771 Mon Sep 17 00:00:00 2001 From: Kaz Kylheku Date: Fri, 8 Dec 2017 18:11:59 -0800 Subject: New feature: structure delegate streams. A new kind of stream object which redirects its operations to the methods of a structure. * Makefile (OBJS): New object file, strudel.o. * lib.c (init): Call new strudel_init function. * lisplib.c (stream_wrap_set_entries, stream_wrap_instantiate): New static functions. (lisplib_init): Arrange for autloading of new stream-wrap.tl. * share/txr/stdlib/stream-wrap.tl: New file. * stream.c (put_string_s, put_char_s, put_byte_s, get_line_s, get_char_s, get_byte_s, unget_char_s, unget_byte_s, put_buf_s, fill_buf_s, flush_s, seek_s, truncate_s, get_prop_s, set_prop_s, get_error_s, get_error_str_s, clear_error_s, get_fd_s): New symbol variables. (stream_init): New symbol variables initialized. Numerous functions registered via these variables now rather than intern(...) expressions. * stream.h (put_string_s, put_char_s, put_byte_s, get_line_s, get_char_s, get_byte_s, unget_char_s, unget_byte_s, put_buf_s, fill_buf_s, flush_s, seek_s, truncate_s, get_prop_s, set_prop_s, get_error_s, get_error_str_s, clear_error_s, get_fd_s): Declared. * strudel.c, strudel.h: New files. --- strudel.h | 30 ++++++++++++++++++++++++++++++ 1 file changed, 30 insertions(+) create mode 100644 strudel.h (limited to 'strudel.h') diff --git a/strudel.h b/strudel.h new file mode 100644 index 00000000..ba41a08a --- /dev/null +++ b/strudel.h @@ -0,0 +1,30 @@ +/* Copyright 2017 + * Kaz Kylheku + * Vancouver, Canada + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions are met: + * + * 1.
