* Avoid redundant copies in string evalsFather Chrysostomos2011-11-061-1/+3
| | | | | | | Perl_lex_start copies the string passed to it unconditionally. Sometimes pp_entereval makes a copy before passing the string to lex_start. So in those cases we can pass a flag to avoid a redundant copy.
* Merge some parser fieldsFather Chrysostomos2011-11-061-3/+3
| | | | | | | By combining two booleans with the flags field, we save some space. By making it a 16-bit instead of 32-bit field (only two flag bits are currently used), we also avoid alignment holes (I hope; I’m not very good at this).
* Make source filters work in evalbytesFather Chrysostomos2011-11-061-1/+5
| | | | | | When a filter is added, the current buffer is hung on the end of the filters array, and a new substring of it becomes the current buffer.
* parser.h: Rearrange constantsFather Chrysostomos2011-11-061-1/+2
| | | | | Put LEX_IGNORE_UTF8_HINTS near the only other constant passed to lex_start
* eval STRING UTF8 cleanup.Brian Fraser2011-11-061-0/+2

* [perl #87064] eval no longer shares filtersFather Chrysostomos2011-04-031-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit: commit f07ec6dd59215a56bc1159449a9631be7a02a94d Author: Zefram <zefram@fysh.org> Date: Wed Oct 13 19:05:19 2010 +0100 remove filter inheritance option from lex_start The only uses of lex_start that had the new_filter parameter false, to make the new lexer context share source filters with the previous lexer context, were uses with rsfp null, which therefore never invoked source filters. Inheriting source filters from a logically unrelated file seems like a silly idea anyway. string evals could inherit the same source filter space as the cur- rently compiling code. Despite what the quoted commit message says, sharing source filters allows filters to be inherited in both direc- tions: A source filter created when the eval is being compiled also applies to the file with which it is sharing its space. There are at least 20 CPAN distributions relying on this behaviour (or, rather, what could be considered a Test::More bug). So this com- mit restores the source-filter-sharing capability. It does not change the current API or make public the API for sharing source filters, as this is supposed to be a temporary stop-gap measure for 5.14.
* recursive-descent expression parsingZefram2010-12-111-2/+19
| | | | | | New API functions parse_fullexpr(), parse_listexpr(), parse_termexpr(), and parse_arithexpr(), to parse an expression at various precedence levels.
* function to parse isolated labelZefram2010-10-251-0/+3
| | | | | | | New API function parse_label() parses a label, separate from statements. If a label has not already been lexed and queued up, it does not use yylex(), but parses the label itself at the character level, to avoid unwanted lexing past an absent optional label.
* replace PL_doextract with better kinds of variableZefram2010-10-211-0/+1
| | | | | | | | PL_doextract had two unrelated jobs, neither best served by an interpreter global variable. The first was to track the -x command-line switch. That is replaced with a local variable in S_parse_body(). The second was to track whether the lexer is in the middle of a =pod section. That is replaced with an element in PL_parser.

* lexer APIZefram2009-11-151-0/+4
| | | | | | | | | Attached is a patch that adds a public API for the lowest layers of lexing. This is meant to provide a solid foundation for the parsing that Devel::Declare and similar modules do, and it complements the pluggable keyword mechanism. The API consists of some existing variables combined with some new functions, all marked as experimental (which making them public certainly is).

* [perl #43425] local $[: fix scoping during parser error handling.Dave Mitchell2007-07-161-0/+1
| | | | | | | | | Change 22306# inadvertently made 'local $[' statement-scoped rather than block-scoped; so revert that change and add a different fix. The problem was to ensure that the savestack got popped correctly while popping errored tokens. We how record the current value of PL_savestack_ix with each pushed parser state. p4raw-id: //depot/perl@31615
