/***************************************************
* A program for testing the Unicode property table *
***************************************************/
/* Copyright (c) University of Cambridge 2008-2023 */
/* Compile thus:
gcc -DHAVE_CONFIG_H -DPCRE2_CODE_UNIT_WIDTH=8 \
-fvisibility=hidden -o ucptest ucptest.c \
../src/pcre2_ord2utf.c ../src/pcre2_ucd.c ../src/pcre2_tables.c
Add -lreadline or -ledit if PCRE2 was configured with readline or libedit
support in pcre2test.
*/
/* This is a hacked-up program for testing the Unicode properties tables of
PCRE2. It can also be used for finding characters with certain properties. I
wrote it to help with debugging, and have added things that I found useful, in
a rather haphazard way. The code has never been seriously tidied or checked for
robustness, but it shouldn't now give compiler warnings.
There is only one option: "-s". If given, it applies only to the "findprop"
command. It causes the UTF-8 sequence of bytes that encode the character to be
output between angle brackets at the end of the line. On a UTF-8 terminal, this
will show the appropriate graphic for the code point.
If the command has arguments, they are concatenated into a buffer, separated by
spaces. If the first argument starts "U+" or consists entirely of hexadecimal
digits, "findprop" is inserted at the start. The buffer is then processed as a
single line file, after which the program exits. If there are no arguments, the
program reads commands line by line on stdin and writes output to stdout. The
return code is always zero.
There are three commands:
The command "findprop" must be followed by a space-separated list of Unicode
code points as hex numbers, either without any prefix or starting with "U+", or
as individual UTF-8 characters preceded by '+'. For example:
findprop U+1234 5Abc +?
The output is one long line per character, listing Unicode properties that have
values, followed by its other case or cases if one or more exist, followed by
its Script Extension list if there is one. This list is in square brackets. A
second list in square brackets gives all the Boolean properties of the
character. The properties that come first are:
Bidi class e.g. NSM (most common is L)
General type e.g. Letter
Specific type e.g. Upper case letter
Script e.g. Medefaidrin
Grapheme break type e.g. Extend (most common is Other)
Script names and Boolean property names are all in lower case, with underscores
and hyphens removed, because that's how they are stored for "loose" matching.
The command "find" must be followed by a list of property types and their
values. The values are case-sensitive, except for bidi class. This finds
characters that have those properties. If multiple properties are listed, they
must all be matched. Currently supported:
script <name> The character must have this script property. Only one
such script may be given.
scriptx <name> This script must be in the character's Script Extension
property list. If this is used many times, all the given
scripts must be present.
type <abbrev> The character's specific type (e.g. Lu or Nd) must match.
gbreak <name> The grapheme break property must match.
bidi <class> The character's bidi class must match.
bool <name> The character's Boolean property list must contain this
property.
If a <name> or <abbrev> is preceded by !, the value must NOT be present. For
Script Extensions and Boolean properties, there may be a mixture of positive
and negative requirements. All must be satisfied.
Sequences of two or more characters are shown as ranges, for example
U+0041..U+004A. No more than 100 lines are output. If there are more
characters, the list ends with ...
The command "list" must be followed by one of property names script, bool,
type, gbreak or bidi. The defined values for that property are listed. */
