From e69a99cc4c183a98dd380fdaf47a5a1dcb5d68a0 Mon Sep 17 00:00:00 2001 From: Kaz Kylheku Date: Thu, 5 Apr 2018 06:53:24 -0700 Subject: printer: improve object formatting. There is an issue with the printer in that it produces output whereby objects continue on the same line after a multi-line object, e.g: (foo (foobly bar xyzzy quux) (oops same line)) rather than: (foo (foobly bar xyzzy quux) (oops same line)) There is a simple fix for this: set a flag to force a line break on the next width-check operation whenever an object has been broken into multiple lines. width-check can return a Boolean indication whether it generated a line break, and so aggregate object printing routines can tell whether their object has been broken into lines, and set the flag. * stream.h (struct strm_base): New member, force_break. (force_break): Declared. * stream.c (strm_base_init): Extent initializer to cover force_break flag. (put_string, put_char): Clear the force_break flag whenever we hit column zero. (width_check): If indent mode is on, and force_break is true, generate a break. Clear force_break. (force_break): New function. (stream_init): Register force-break intrinsic. * buf.c (buf_print): Set the force break flag if the buffer was broken into multiple lines. * hash.c (hash_print_op): Set the force break flag if the hash was broken into multiple lines. * lib.c (obj_print_impl): Same logic for lists. * struct.c (struct_inst_print): Same logic for structs. * tests/009/json.expected, tests/011/macros-2.expected, tests/012/struct.tl, tests/017/glob-zarray.expected: Update expected textual output to reflect new formatting. --- tests/017/glob-zarray.expected | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'tests/017') diff --git a/tests/017/glob-zarray.expected b/tests/017/glob-zarray.expected index 4bfc0810..cd54b421 100644 --- a/tests/017/glob-zarray.expected +++ b/tests/017/glob-zarray.expected @@ -1,3 +1,4 @@ 0 #S(glob-t pathc 4 pathv #("tests/001/query-1.txr" "tests/001/query-2.txr" "tests/001/query-3.txr" - "tests/001/query-4.txr") reserve 0) + "tests/001/query-4.txr") + reserve 0) -- cgit v1.2.3
