ext/json/parser/prereq.mk: Add a "automatically generated" header to parser.c. 2019-10-04 18:00:07 -04:00			`-e '$$_.sub!(/^static const int (JSON_.=.);$$/, "enum {\\1};")' \`
ext/json/parser/prereq.mk: remove type-limit warning if char is unsigned Ragel generates a code `0 <= (p)` where `p` is char. As char is unsigned by default on arm and RISC-V, it is warned by gcc: ``` compiling parser.c parser.c: In function ‘JSON_parse_string’: parser.c:1566:2: warning: comparison is always true due to limited range of data type [-Wtype-limits] if ( 0 <= (p) && (p) <= 31 ) ^ parser.c:1596:2: warning: comparison is always true due to limited range of data type [-Wtype-limits] if ( 0 <= (p) && (p) <= 31 ) ^ ``` This change removes the warning by substituting the condition with `0 <= (signed char)(*p)`. 2020-05-13 11:44:35 -04:00			`-e '$$_.sub!(/0 <= \(\p\) && \(\p\) <= 31/, "0 <= (signed char)(p) && (p) <= 31")' \`
ext/json/parser/prereq.mk: use `if $. == 1` instead of a hacky code 2019-10-05 05:28:19 -04:00			`-e '$$_ = "/* This file is automatically generated from parser.rl by using ragel */" + $$_ if $$. == 1' $@`
