| |
| This function performs a conformance test for implementations of the |
| Unicode Bidirectional Algorithm, specified in UAX #9: Unicode |
| Bidirectional Algorithm, at https://www.unicode.org/reports/tr9/ |
| |
| Each test case is represented in a single line which is read from a file |
| named BidiCharacter.txt. Empty, blank and comment lines may also appear |
| in this file. |
| |
| The format of the test data is specified below. Note that each test |
| case constitutes a single line of text; reordering is applied within a |
| single line and independently of a rendering engine, and rules L3 and L4 |
| are out of scope. |
| |
| The number sign '#' is the comment character: everything is ignored from |
| the occurrence of '#' until the end of the line, |
| Empty lines and lines containing only spaces and/or comments are ignored. |
| |
| Lines which represent test cases consist of 4 or 5 fields separated by a |
| semicolon. Each field consists of tokens separated by whitespace (space |
| or Tab). Whitespace before and after semicolons is optional. |
| |
| Field 0: A sequence of hexadecimal code point values separated by space |
| |
| Field 1: A value representing the paragraph direction, as follows: |
| - 0 represents left-to-right |
| - 1 represents right-to-left |
| - 2 represents auto-LTR according to rules P2 and P3 of the algorithm |
| - 3 represents auto-RTL according to rules P2 and P3 of the algorithm |
| - a negative number whose absolute value is taken as paragraph level; |
| this may be useful to test cases where the embedding level approaches |
| or exceeds the maximum embedding level. |
| |
| Field 2: The resolved paragraph embedding level. If the input (field 0) |
| includes more than one paragraph, this field represents the |
| resolved level of the first paragraph. |
| |
| Field 3: An ordered list of resulting levels for each token in field 0 |
| (each token represents one source character). |
| The UBA does not assign levels to certain characters (e.g. LRO); |
| characters removed in rule X9 are indicated with an 'x'. |
| |
| Field 4: An ordered list of indices showing the resulting visual ordering |
| from left to right; characters with a resolved level of 'x' are |
| skipped. The number are zero-based. Each index corresponds to |
| a character in the reordered (visual) string. It represents the |
| index of the source character in the input (field 0). |
| This field is optional. When it is absent, the visual ordering |
| is not verified. |
| |
| Examples: |
| |
| # This is a comment line. |
| L L ON R ; 0 ; 0 ; 0 0 0 1 ; 0 1 2 3 |
| L L ON R;0;0;0 0 0 1;0 1 2 3 |
| |
| # Note: in the next line, 'B' represents a block separator, not the letter 'B'. |
| LRE A B C PDF;2;0;x 2 0 0 x;1 2 3 |
| # Note: in the next line, 'b' represents the letter 'b', not a block separator. |
| a b c 05d0 05d1 x ; 0 ; 0 ; 0 0 0 1 1 0 ; 0 1 2 4 3 5 |
| |
| a R R x ; 1 ; 1 ; 2 1 1 2 |
| L L R R R B R R L L L B ON ON ; 3 ; 0 ; 0 0 1 1 1 0 1 1 2 2 2 1 1 1 |
