# Generate utt tables. Note: this script is written in Python 2 and is
|

# incompatible with Python 3. However, the 2to3 conversion script has been

# successfully tested on it.

# The source file pcre2_tables.c contains (amongst other things), a table that
|
||||||
|
# is indexed by script name. In order to reduce the number of relocations when
|
||||||
|
# loading the library, the names are held as a single large string, with
|
||||||
|
# offsets in the table. This is tedious to maintain by hand. Therefore, this
|
||||||
|
# script is used to generate the table. The output is sent to stdout; usually
|
||||||
|
# that should be directed to a temporary file. Then pcre2_tables.c can be
|
||||||
|
# edited by replacing the relevant definitions and table therein with the
|
||||||
|
# temporary file.

|
# This script was submitted to the PCRE project by Peter Kankowski as part of
|
||||||
|
# the upgrading of Unicode property support. The new code speeds up property
|
||||||
|
# matching many times. The script is for the use of PCRE maintainers, to
|
||||||
|
# generate the pcre_ucd.c file that contains a digested form of the Unicode
|
||||||
|
# data tables.
|
||||||
|
#
|
||||||
|
# The script should be run in the maint subdirectory, using the command
|
||||||
|
#
|
||||||
|
# [python2] ./MultiStage2.py >../src/pcre2_ucd.c
|
||||||
|
#
|
||||||
|
# It requires four Unicode data tables, DerivedGeneralCategory.txt,
|
||||||
|
# GraphemeBreakProperty.txt, Scripts.txt, and CaseFolding.txt, to be in the
|
||||||
|
# Unicode.tables subdirectory. The first of these is found in the "extracted"
|
||||||
|
# subdirectory of the Unicode database (UCD) on the Unicode web site; the
|
||||||
|
# second is in the "auxiliary" subdirectory; the other two are directly in the
|
||||||
|
# UCD directory.
|
||||||
|
#
|
||||||
|
# Minor modifications made to this script:
|
||||||
|
# Added #! line at start
|
||||||
|
# Removed tabs
|
||||||
|
# Made it work with Python 2.4 by rewriting two statements that needed 2.5
|
||||||
|
# Consequent code tidy
|
||||||
|
# Adjusted data file names to take from the Unicode.tables directory
|
||||||
|
# Adjusted global table names by prefixing _pcre_.
|
||||||
|
# Commented out stuff relating to the casefolding table, which isn't used;
|
||||||
|
# removed completely in 2012.
|
||||||
|
# Corrected size calculation
|
||||||
|
# Add #ifndef SUPPORT_UCP to use dummy tables when no UCP support is needed.
|
||||||
|
# Update for PCRE2: name changes and SUPPORT_UCP is abolished.
|
||||||
|
#
|
||||||
|
# Major modifications made to this script:
|
||||||
|
# Added code to add a grapheme break property field to records.
|
||||||
|
#
|
||||||
|
# Added code to search for sets of more than two characters that must match
|
||||||
|
# each other caselessly. A new table is output containing these sets, and
|
||||||
|
# offsets into the table are added to the main output records. This new
|
||||||
|
# code scans CaseFolding.txt instead of UnicodeData.txt.
|
||||||
|
#
|
||||||
|
# The main tables generated by this script are used by macros defined in
|
||||||
|
# pcre2_internal.h. They look up Unicode character properties using short
|
||||||
|
# sequences of code that contains no branches, which makes for greater speed.
|
||||||
|
#
|
||||||
|
# Conceptually, there is a table of records (of type ucd_record), containing a
|
||||||
|
# script number, character type, grapheme break type, offset to caseless
|
||||||
|
# matching set, and offset to the character's other case for every character.
|
||||||
|
# However, a real table covering all Unicode characters would be far too big.
|
||||||
|
# It can be efficiently compressed by observing that many characters have the
|
||||||
|
# same record, and many blocks of characters (taking 128 characters in a block)
|
||||||
|
# have the same set of records as other blocks. This leads to a 2-stage lookup
|
||||||
|
# process.
|
||||||
|
#
|
||||||
|
# This script constructs four tables. The ucd_caseless_sets table contains
|
||||||
|
# lists of characters that all match each other caselessly. Each list is
|
||||||
|
# in order, and is terminated by NOTACHAR (0xffffffff), which is larger than
|
||||||
|
# any valid character. The first list is empty; this is used for characters
|
||||||
|
# that are not part of any list.
|
||||||
|
#
|
||||||
|
# The ucd_records table contains one instance of every unique record that is
|
||||||
|
# required. The ucd_stage1 table is indexed by a character's block number, and
|
||||||
|
# yields what is in effect a "virtual" block number. The ucd_stage2 table is a
|
||||||
|
# table of "virtual" blocks; each block is indexed by the offset of a character
|
||||||
|
# within its own block, and the result is the offset of the required record.
|
||||||
|
#
|
||||||
|
# Example: lowercase "a" (U+0061) is in block 0
|
||||||
|
# lookup 0 in stage1 table yields 0
|
||||||
|
# lookup 97 in the first table in stage2 yields 16
|
||||||
|
# record 17 is { 33, 5, 11, 0, -32 }
|
||||||
|
# 33 = ucp_Latin => Latin script
|
||||||
|
# 5 = ucp_Ll => Lower case letter
|
||||||
|
# 11 = ucp_gbOther => Grapheme break property "Other"
|
||||||
|
# 0 => not part of a caseless set
|
||||||
|
# -32 => Other case is U+0041
|
||||||
|
#
|
||||||
|
# Almost all lowercase latin characters resolve to the same record. One or two
|
||||||
|
# are different because they are part of a multi-character caseless set (for
|
||||||
|
# example, k, K and the Kelvin symbol are such a set).
|
||||||
|
#
|
||||||
|
# Example: hiragana letter A (U+3042) is in block 96 (0x60)
|
||||||
|
# lookup 96 in stage1 table yields 88
|
||||||
|
# lookup 66 in the 88th table in stage2 yields 467
|
||||||
|
# record 470 is { 26, 7, 11, 0, 0 }
|
||||||
|
# 26 = ucp_Hiragana => Hiragana script
|
||||||
|
# 7 = ucp_Lo => Other letter
|
||||||
|
# 11 = ucp_gbOther => Grapheme break property "Other"
|
||||||
|
# 0 => not part of a caseless set
|
||||||
|
# 0 => No other case
|
||||||
|
#
|
||||||
|
# In these examples, no other blocks resolve to the same "virtual" block, as it
|
||||||
|
# happens, but plenty of other blocks do share "virtual" blocks.
|
||||||
|
#
|
||||||
|
# There is a fourth table, maintained by hand, which translates from the
|
||||||
|
# individual character types such as ucp_Cc to the general types like ucp_C.

# Philip Hazel, 03 July 2008
|
||||||
|
#
|
||||||
|
# 01-March-2010: Updated list of scripts for Unicode 5.2.0
|
||||||
|
# 30-April-2011: Updated list of scripts for Unicode 6.0.0
|
||||||
|
# July-2012: Updated list of scripts for Unicode 6.1.0
|
||||||
|
# 20-August-2012: Added scan of GraphemeBreakProperty.txt and added a new
|
||||||
|
# field in the record to hold the value. Luckily, the
|
||||||
|
# structure had a hole in it, so the resulting table is
|
||||||
|
# not much bigger than before.
|
||||||
|
# 18-September-2012: Added code for multiple caseless sets. This uses the
|
||||||
|
# final hole in the structure.
|
||||||
|
# 30-September-2012: Added RegionalIndicator break property from Unicode 6.2.0
|
||||||
|
# 13-May-2014: Updated for PCRE2

MAINTENANCE README FOR PCRE2
|
||||||
|
============================
|
||||||
|
|
||||||
|
The files in the "maint" directory of the PCRE2 source contain data, scripts,
|
||||||
|
and programs that are used for the maintenance of PCRE2, but which do not form
|
||||||
|
part of the PCRE2 distribution tarballs. This document describes these files
|
||||||
|
and also contains some notes for maintainers. Its contents are:
|

||||||
|
Files in the maint directory
|
||||||
|
============================
|
||||||
|
|
||||||
|
GenerateUtt.py A Python script to generate part of the pcre2_tables.c file
|
||||||
|
that contains Unicode script names in a long string with
|
||||||
|
offsets, which is tedious to maintain by hand.
|
||||||
|
|
||||||
|
ManyConfigTests A shell script that runs "configure, make, test" a number of
|
||||||
|
times with different configuration settings.
|
||||||
|
|
||||||
|
MultiStage2.py A Python script that generates the file pcre2_ucd.c from three
|
||||||
|
Unicode data tables, which are themselves downloaded from the
|
||||||
|
Unicode web site. Run this script in the "maint" directory.
|
||||||
|
The generated file contains the tables for a 2-stage lookup
|
||||||
|
of Unicode properties.
|
||||||
|
|
||||||
|
pcre2_chartables.c.non-standard
|
||||||
|
This is a set of character tables that came from a Windows
|
||||||
|
system. It has characters greater than 128 that are set as
|
||||||
|
spaces, amongst other things. I kept it so that it can be
|
||||||
|
used for testing from time to time.
|
||||||
|
|
||||||
|
README This file.
|
||||||
|
|
||||||
|
Unicode.tables The files in this directory (CaseFolding.txt,
|
||||||
|
DerivedGeneralCategory.txt, GraphemeBreakProperty.txt,
|
||||||
|
Scripts.txt and UnicodeData.txt) were downloaded from the
|
||||||
|
Unicode web site. They contain information about Unicode
|
||||||
|
characters and scripts.
|
||||||
|
|
||||||
|
ucptest.c A short C program for testing the Unicode property macros
|
||||||
|
that do lookups in the pcre2_ucd.c data, mainly useful after
|
||||||
|
rebuilding the Unicode property table. Compile and run this in
|
||||||
|
the "maint" directory (see comments at its head).
|
||||||
|
|
||||||
|
ucptestdata A directory containing two files, testinput1 and testoutput1,
|
||||||
|
to use in conjunction with the ucptest program.
|
||||||
|
|
||||||
|
utf8.c A short, freestanding C program for converting a Unicode code
|
||||||
|
point into a sequence of bytes in the UTF-8 encoding, and vice
|
||||||
|
versa. If its argument is a hex number such as 0x1234, it
|
||||||
|
outputs a list of the equivalent UTF-8 bytes. If its argument
|
||||||
|
is sequence of concatenated UTF-8 bytes (e.g. e188b4) it
|
||||||
|
treats them as a UTF-8 character and outputs the equivalent
|
||||||
|
code point in hex.
|
||||||
|
|
||||||
|
|
||||||
|
Updating to a new Unicode release
|
||||||
|
=================================
|
||||||
|
|
||||||
|
When there is a new release of Unicode, the files in Unicode.tables must be
|
||||||
|
refreshed from the web site. If the new version of Unicode adds new character
|
||||||
|
scripts, the source file pacr2_ucp.h and both the MultiStage2.py and the
|
||||||
|
GenerateUtt.py scripts must be edited to add the new names. Then MultiStage2.py
|
||||||
|
can be run to generate a new version of pcre2_ucd.c, and GenerateUtt.py can be
|
||||||
|
run to generate the tricky tables for inclusion in pcre2_tables.c.
|
||||||
|
|
||||||
|
If MultiStage2.py gives the error "ValueError: list.index(x): x not in list",
|
||||||
|
the cause is usually a missing (or misspelt) name in the list of scripts. I
|
||||||
|
couldn't find a straightforward list of scripts on the Unicode site, but
|
||||||
|
there's a useful Wikipedia page that list them, and notes the Unicode version
|
||||||
|
in which they were introduced:
|
||||||
|
|
||||||
|
http://en.wikipedia.org/wiki/Unicode_scripts#Table_of_Unicode_scripts
|
||||||
|
|
||||||
|
The ucptest program can be compiled and used to check that the new tables in
|
||||||
|
pcre2_ucd.c work properly, using the data files in ucptestdata to check a
|
||||||
|
number of test characters. The source file ucptest.c must be updated whenever
|
||||||
|
new Unicode script names are added.
|
||||||
|
|
||||||
|
Note also that both the pcre2syntax.3 and pcre2pattern.3 man pages contain
|
||||||
|
lists of Unicode script names.
|
||||||
|
|
||||||
|
|
||||||
|
Preparing for a PCRE release
|
||||||
|
============================
|
||||||
|
|
||||||
|
This section contains a checklist of things that I consult before building a
|
||||||
|
distribution for a new release.
|
||||||
|
|
||||||
|
. Ensure that the version number and version date are correct in configure.ac.
|
||||||
|
|
||||||
|
. Update the library version numbers in configure.ac according to the rules
|
||||||
|
given below.
|
||||||
|
|
||||||
|
. If new build options have been added, ensure that they are added to the CMake
|
||||||
|
files as well as to the autoconf files. The relevant files are CMakeLists.txt
|
||||||
|
and config-cmake.h.in. After making a release tarball, test it out with CMake
|
||||||
|
if there have been changes here.
|
||||||
|
|
||||||
|
. Run ./autogen.sh to ensure everything is up-to-date.
|
||||||
|
|
||||||
|
. Compile and test with many different config options, and combinations of
|
||||||
|
options. Also, test with valgrind by running "RunTest valgrind" and
|
||||||
|
"RunGrepTest valgrind" (which takes quite a long time). The script
|
||||||
|
maint/ManyConfigTests now encapsulates this testing. It runs tests with
|
||||||
|
different configurations, and it also runs some of them with valgrind, all of
|
||||||
|
which can take quite some time.
|
||||||
|
|
||||||
|
. Run perltest.pl on the test data for tests 1, 4, and 6. The output
|
||||||
|
should match the PCRE2 test output, apart from the version identification at
|
||||||
|
the start of each test. The other tests are not Perl-compatible (they use
|
||||||
|
various PCRE2-specific features or options).
|
||||||
|
|
||||||
|
. It is possible to test with the emulated memmove() function by undefining
|
||||||
|
HAVE_MEMMOVE and HAVE_BCOPY in config.h, though I do not do this often. You
|
||||||
|
may see a number of "pcre2_memmove defined but not used" warnings for the
|
||||||
|
modules in which there is no call to memmove(). These can be ignored.
|
||||||
|
|
||||||
|
. Documentation: check AUTHORS, ChangeLog (check version and date), LICENCE,
|
||||||
|
NEWS (check version and date), NON-AUTOTOOLS-BUILD, and README. Many of these
|
||||||
|
won't need changing, but over the long term things do change.
|
||||||
|
|
||||||
|
. I used to test new releases myself on a number of different operating
|
||||||
|
systems, using different compilers as well. For example, on Solaris it is
|
||||||
|
helpful to test using Sun's cc compiler as a change from gcc. Adding
|
||||||
|
-xarch=v9 to the cc options does a 64-bit test, but it also needs -S 64 for
|
||||||
|
pcretest to increase the stack size for test 2. Since I retired I can no
|
||||||
|
longer do this, but instead I rely on putting out release candidates for
|
||||||
|
folks on the pcre-dev list to test.

Updating version info for libtool
|
||||||
|
=================================
|
||||||
|
|
||||||
|
This set of rules for updating library version information came from a web page
|
||||||
|
whose URL I have forgotten. The version information consists of three parts:
|
||||||
|
(current, revision, age).
|
||||||
|
|
||||||
|
1. Start with version information of 0:0:0 for each libtool library.
|
||||||
|
|
||||||
|
2. Update the version information only immediately before a public release of
|
||||||
|
your software. More frequent updates are unnecessary, and only guarantee
|
||||||
|
that the current interface number gets larger faster.
|
||||||
|
|
||||||
|
3. If the library source code has changed at all since the last update, then
|
||||||
|
increment revision; c:r:a becomes c:r+1:a.
|
||||||
|
|
||||||
|
4. If any interfaces have been added, removed, or changed since the last
|
||||||
|
update, increment current, and set revision to 0.
|
||||||
|
|
||||||
|
5. If any interfaces have been added since the last public release, then
|
||||||
|
increment age.
|
||||||
|
|
||||||
|
6. If any interfaces have been removed or changed since the last public
|
||||||
|
release, then set age to 0.
|
||||||
|
|
||||||
|
The following explanation may help in understanding the above rules a bit
|
||||||
|
better. Consider that there are three possible kinds of reaction from users to
|
||||||
|
changes in a shared library:
|
||||||
|
|
||||||
|
1. Programs using the previous version may use the new version as a drop-in
|
||||||
|
replacement, and programs using the new version can also work with the
|
||||||
|
previous one. In other words, no recompiling nor relinking is needed. In
|
||||||
|
this case, increment revision only, don't touch current or age.
|
||||||
|
|
||||||
|
2. Programs using the previous version may use the new version as a drop-in
|
||||||
|
replacement, but programs using the new version may use APIs not present in
|
||||||
|
the previous one. In other words, a program linking against the new version
|
||||||
|
may fail if linked against the old version at run time. In this case, set
|
||||||
|
revision to 0, increment current and age.
|
||||||
|
|
||||||
|
3. Programs may need to be changed, recompiled, relinked in order to use the
|
||||||
|
new version. Increment current, set revision and age to 0.
|
||||||
|
|
||||||
|
|
||||||
|
Making a PCRE release
|
||||||
|
=====================
|
||||||
|
|
||||||
|
Run PrepareRelease and commit the files that it changes (by removing trailing
|
||||||
|
spaces). The first thing this script does is to run CheckMan on the man pages;
|
||||||
|
if it finds any markup errors, it reports them and then aborts.
|
||||||
|
|
||||||
|
Once PrepareRelease has run clean, run "make distcheck" to create the tarballs
|
||||||
|
and the zipball. Double-check with "svn status", then create an SVN tagged
|
||||||
|
copy:
|
||||||
|
|
||||||
|
svn copy svn://vcs.exim.org/pcre2/code/trunk \
|
||||||
|
svn://vcs.exim.org/pcre2/code/tags/pcre-8.xx
|
||||||
|
|
||||||
|
Don't forget to update Freecode (fka Freshmeat) when the new release is out,
|
||||||
|
and to tell webmaster@pcre.org and the mailing list. Also, update the list of
|
||||||
|
version numbers in Bugzilla (edit products).
|
||||||
|
|
||||||
|
|
||||||
|
Future ideas (wish list)
|
||||||
|
========================
|
||||||
|
|
||||||
|
This section records a list of ideas so that they do not get forgotten. They
|
||||||
|
vary enormously in their usefulness and potential for implementation. Some are
|
||||||
|
very sensible; some are rather wacky. Some have been on this list for years;
|
||||||
|
others are relatively new.
|
||||||
|
|
||||||
|
. Optimization
|
||||||
|
|
||||||
|
There are always ideas for new optimizations so as to speed up pattern
|
||||||
|
matching. Most of them try to save work by recognizing a non-match without
|
||||||
|
having to scan all the possibilities. These are some that I've recorded:
|
||||||
|
|
||||||
|
* /((A{0,5}){0,5}){0,5}(something complex)/ on a non-matching string is very
|
||||||
|
slow, though Perl is fast. Can we speed up somehow? Convert to {0,125}?
|
||||||
|
OTOH, this is pathological - the user could easily fix it.
|
||||||
|
|
||||||
|
* Turn ={4} into ==== ? (for speed). I once did an experiment, and it seems
|
||||||
|
to have little effect, and maybe makes things worse.
|
||||||
|
|
||||||
|
* "Ends with literal string" - note that a single character doesn't gain much
|
||||||
|
over the existing "required byte" (reqbyte) feature that just remembers one
|
||||||
|
data unit.
|
||||||
|
|
||||||
|
* Remember an initial string rather than just 1 code unit?
|
||||||
|
|
||||||
|
* A required code unit from alternatives - not just the last unit, but an
|
||||||
|
earlier one if common to all alternatives.
|
||||||
|
|
||||||
|
o Friedl contains other ideas.
|
||||||
|
|
||||||
|
* The code does not set initial code unit flags for Unicode property types
|
||||||
|
such as \p; I don't know how much benefit there would be for, for example,
|
||||||
|
setting the bits for 0-9 and all values >= xC0 (in 8-bit mode) when a
|
||||||
|
pattern starts with \p{N}.
|
||||||
|
|
||||||
|
* There is scope for more "auto-possessifying" in connection with \p and \P.
|
||||||
|
|
||||||
|
. If Perl gets to a consistent state over the settings of capturing sub-
|
||||||
|
patterns inside repeats, see if we can match it. One example of the
|
||||||
|
difference is the matching of /(main(O)?)+/ against mainOmain, where PCRE
|
||||||
|
leaves $2 set. In Perl, it's unset. Changing this in PCRE will be very hard
|
||||||
|
because I think it needs much more state to be remembered.
|
||||||
|
|
||||||
|
. Perl 6 will be a revolution. Is it a revolution too far for PCRE?
|
||||||
|
|
||||||
|
. Allow errorptr and erroroffset to be NULL. I don't like this idea.
|
||||||
|
|
||||||
|
. Line endings:
|
||||||
|
|
||||||
|
* Option to use NUL as a line terminator in subject strings. This could now
|
||||||
|
be done relatively easily since the extension to support LF, CR, and CRLF.
|
||||||
|
If it is done, a suitable option for pcregrep is also required.
|
||||||
|
|
||||||
|
. Catch SIGSEGV for stack overflows?
|
||||||
|
|
||||||
|
. A feature to suspend a match via a callout was once requested.
|
||||||
|
|
||||||
|
. Option to convert results into character offsets and character lengths.
|
||||||
|
|
||||||
|
. Option for pcregrep to scan only the start of a file. I am not keen - this is
|
||||||
|
the job of "head".
|
||||||
|
|
||||||
|
. A (non-Unix) user wanted pcregrep options to (a) list a file name just once,
|
||||||
|
preceded by a blank line, instead of adding it to every matched line, and (b)
|
||||||
|
support --outputfile=name.
|
||||||
|
|
||||||
|
. Consider making UTF and UCP the default for PCRE n.0 for some n > 8.
|
||||||
|
|
||||||
|
. Define a union for the results from pcre2_pattern_info().
|
||||||
|
|
||||||
|
. Provide a "random access to the subject" facility so that the way in which it
|
||||||
|
is stored is independent of PCRE. For efficiency, it probably isn't possible
|
||||||
|
to switch this dynamically. It would have to be specified when PCRE was
|
||||||
|
compiled. PCRE would then call a function every time it wanted a character.
|
||||||
|
|
||||||
|
. Wild thought: the ability to compile from PCRE's internal byte code to a real
|
||||||
|
FSM and a very fast (third) matcher to process the result. There would be
|
||||||
|
even more restrictions than for pcre_dfa_exec(), however. This is not easy.
|
||||||
|
This is probably obsolete now that we have the JIT support.
|
||||||
|
|
||||||
|
. Should pcretest have some private locale data, to avoid relying on the
|
||||||
|
available locales for the test data, since different OS have different ideas?
|
||||||
|
This won't be as thorough a test, but perhaps that doesn't really matter.
|
||||||
|
|
||||||
|
. pcregrep: add -rs for a sorted recurse? Having to store file names and sort
|
||||||
|
them will of course slow it down.
|
||||||
|
|
||||||
|
. Someone suggested --disable-callout to save code space when callouts are
|
||||||
|
never wanted. This seems rather marginal.
|
||||||
|
|
||||||
|
. A user suggested a parameter to limit the length of string matched, for
|
||||||
|
example if the parameter is N, the current match should fail if the matched
|
||||||
|
substring exceeds N. This could apply to both match functions. The value
|
||||||
|
could be a new field in the extra block.
|
||||||
|
|
||||||
|
. Callouts with arguments: (?Cn:ARG) for instance.
|
||||||
|
|
||||||
|
. Write a function that generates random matching strings for a compiled regex.
|
||||||
|
|
||||||
|
. Pcregrep: an option to specify the output line separator, either as a string
|
||||||
|
or select from a fixed list. This is not dead easy, because at the moment it
|
||||||
|
outputs whatever is in the input file.
|
||||||
|
|
||||||
|
. Improve the code for duplicate checking in pcre_dfa_exec(). An incomplete,
|
||||||
|
non-thread-safe patch showed that this can help performance for patterns
|
||||||
|
where there are many alternatives. However, a simple thread-safe
|
||||||
|
implementation that I tried made things worse in many simple cases, so this
|
||||||
|
is not an obviously good thing.
|
||||||
|
|
||||||
|
. PCRE cannot at present distinguish between subpatterns with different names,
|
||||||
|
but the same number (created by the use of ?|). In order to do so, a way of
|
||||||
|
remembering *which* subpattern numbered n matched is needed. Bugzilla #760.
|
||||||
|
Now that (*MARK) has been implemented, it can perhaps be used as a way round
|
||||||
|
this problem.
|
||||||
|
|
||||||
|
. Instead of having #ifdef HAVE_CONFIG_H in each module, put #include
|
||||||
|
"something" and the the #ifdef appears only in one place, in "something".

/* A test program for converting characters to UTF-8 and vice versa. Note that
|
||||||
|
this program conforms to the original definition of UTF-8, which allows
|
||||||
|
codepoints up to 7fffffff. The more recent definition limits the validity of
|
||||||
|
UTF-8 codepoints to a maximum of 10ffffff.
|
||||||
|
|
||||||
|
The arguments are either single codepoint values, written as 0xhhhh, for
|
||||||
|
conversion to UTF-8, or sequences of hex values, written without 0x and
|
||||||
|
optionally including spaces (but such arguments must be quoted), for conversion
|
||||||
|
from UTF-8 to codepoints. For example:
|
||||||
|
|
||||||
|
./utf8 0x1234
|
||||||
|
0x00001234 => e1 88 b4
|
||||||
|
|
||||||
|
./utf8 "e1 88 b4"
|
||||||
|
0x00001234 <= e1 88 b4
|
||||||
|
|
||||||
|
In the second case, a number of characters can be present in one argument:
|
||||||
|
|
||||||
|
./utf8 "65 e188b4 77"
|
||||||
|
0x00000065 <= 65
|
||||||
|
0x00001234 <= e1 88 b4
|
||||||
|
0x00000077 <= 77
|
||||||
|
|
||||||
|
If the option -s is given, the sequence of UTF-bytes is written out between
|
||||||
|
angle brackets at the end of the line. On a UTF-8 terminal, this will show the
|
||||||
|
appropriate graphic for the codepoint. */

for example, to link from the start of a subpattern to its alternatives and its
|
||||||
|
end. The use of 16 bits per offset limits the size of an 8-bit compiled regex
|
||||||
|
to around 64K, which is big enough for almost everybody. However, I received a
|
||||||
|
request for an even bigger limit. For this reason, and also to make the code
|
||||||
|
easier to maintain, the storing and loading of offsets from the compiled code
|
||||||
|
unit string is now handled by the macros that are defined here.
|
||||||
|
|
||||||
|
The macros are controlled by the value of LINK_SIZE. This defaults to 2, but
|
||||||
|
values of 2 or 4 are also supported. */
