* Move regen scripts to regen/Steffen Mueller2010-10-101-320/+0
| | | | | Moves the various scripts that are called by regen.pl to a subdirectory to reduce clutter.
* Ensure regen.pl and the scripts that it calls can be run by older perls.Nicholas Clark2010-09-221-11/+10
| | | | | | | As the internal comments state, they may be all that is available, particularly if trying to port something to an obscure platform. There's not that much that needs changing to get back to 5.005, or from there to 5.004, but beyond there is hard work, and really not worth it.
* Refactor common parts of op.h, regexp.h into new .hKarl Williamson2010-07-291-22/+25
| | | | | | | | | | | op.h and regexp.h share common elements in their data structures. They have had to manually be kept in sync. This patch makes it easier by putting those common parts into a common header #included by the two. To do this, it seemed easiest to change the symbol definitions to use left shifts to generate the flag bits. But this meant that regcomp.pl and axt/B/defsubs_h.PL had to be taught to recognize those forms of expressions, done in separate commits
* regcomp.pl: Teach to handle wider range of exprsKarl Williamson2010-07-291-7/+22
| | | | | | | In particular teach it to handle definitions using <<, e.g. #define SYMBOL (1<<3) and to remember previous symbol definitons in the file so that symbol can be used in later definitions.
* Convert REGNODE_{SIMPLE,VARIES} to a bitmask lookup, from a strchr() lookup.Nicholas Clark2010-05-271-4/+28
| | | | | | | This is O(1) with no branching, instead of O(n) with branching. Deprecate the old implementation's externally visible variables PL_simple and PL_varies. Google codesearch suggests that nothing outside the core regexp code was using these.
* Change regcomp.pl to 0-based indexing for its arrays and loops.Nicholas Clark2010-05-271-21/+20
|
* Encapsulate lookups in PL_{varies,simple} within macros REGNODE_{VARIES,SIMPLE}Nicholas Clark2010-05-271-0/+2
| | | | This allows the implementation of the lookup mechanism to change.
* Generate PL_simple[] and PL_varies[] with regcomp.pl, rather than hard-coding.Nicholas Clark2010-05-271-3/+38
| | | | | | Add a new flags column to regcomp.sym, with V if the node type is in PL_varies, S if it is in PL_simple, and . if a placeholder is needed because subsequent optional columns are present.
* Re-work the regcomp.sym to remove use of hard tabs. No data change.Nicholas Clark2010-05-271-2/+2
| | | | | The tab separating name and type is replaced with whitespace, the tab marking the start of the description is replaced by a semicolon.

* Drag autodoc.pl and overload.pl into the age of safer_open().Nicholas Clark2008-03-171-1/+1
| | | | | | | | Thanks to the wisdom of london.pm, stuff the filename into the SCALAR slot of the typeglob created in safer_open(), so that ... Add safer_close(), that will die (with the filename) if the close fails. p4raw-id: //depot/perl@33539
* Rename safer_rename() to rename_if_different(), to accurately describeNicholas Clark2008-03-151-23/+21
| | | | | | | | | | | | | what it does. Use File::Compare rather than Digest::MD5, as the files are small enough to simply read in. (File::Compare dates from 5.004) Remove safer_rename_always(), which isn't used. DRY by replacing the cargo-culted "open or die" with a new function safer_open(), which uses Gensym (5.002) to create an anonymous file handle, and opens and binmodes the file, or dies. This necessitates replacing bareword file handles with lexicals in all the callers. Correct the names of files in close or die constructions. p4raw-id: //depot/perl@33538

* Change 30461 was wrong. As ext/re (re)builds the regexp engine withNicholas Clark2007-03-051-5/+3
| | | | | | | -DDEBUGGING, it's going to need PL_reg_name even if core perl doesn't. So something is always going to use it, so always define it, and always export it. (But only define it once, so that static builds work.) p4raw-id: //depot/perl@30464
* Define and initialise reg_name only once.Nicholas Clark2007-03-031-6/+7
| | | | | | | This allows re to be a static extension. As it's now no-longer a static variable in regcomp.c, it needs a PL_ prefix. p4raw-id: //depot/perl@30451
