| | | | | | | | | NODE_HASH#nd_brace is a flag that is 1 for `foo({ k: 1 })` and 0 for `foo(k: 1)`. nd_alen had been abused for the flag (and the implementation is completely the same), but an explicit name is better to read. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@67266 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

| | | | | | | | This is NG. The ISO C section 6.7.2.1 explicitly states that structs having flexible array members "shall not be a member of a structure or an element of an array." git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61875 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* node.c: Stop double meaning of NODE_FOR by introducing NODE_FOR_MASGNmame2018-01-161-0/+8
| | | | | | | | | NODE_FOR was used both for "for"-statement itself and for multi-assignment of for-statement (for x, y, in...end). This change separates the two purposes, NODE_FOR for the former, and newly introduced NODE_FOR_MASGN for the latter. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61871 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* Rename code_range to code_locationmame2018-01-091-5/+5
| | | | | | | | | | | Because the name "code_range" is ambiguous with encoding's. Abbreviations ("crange", and "cr") are also renamed to "loc". The traditional "code_location" (a pair of lineno and column) is renamed to "code_position". Abbreviations are also renamed (first_loc to beg_pos, and last_loc to end_pos). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61721 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* parse.y: Make consistent with the terms about code ranges and locationsmame2018-01-081-4/+4
| | | | | | | | | | | | | "loc" was ambiguous; it might refer both a location and a code range. This change uses "loc" for a location, and "crange" or "cr" for a code range. A location (abbr. loc) is a point in a program and consists of line number and column number. A code range (abbr. crange and cr) is a range within a program and consists of a pair of locations which is the first and the last. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61690 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* node.h: remove NODE_PRELUDEmame2018-01-051-44/+0
| | | | | | | | | | | NODE_PRELUDE contains a `BEGIN` node, a main node, and compile_option. This node is assumed that it must be located immediately under the root NODE_SCOPE, but this strange assumption is not so good, IMO. This change removes the assumtion; it integrates the former two nodes by block_append, and moves compile_option into rb_ast_body_t. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61610 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
