160 * File format for .res resource bundle files
161 *
162 * ICU 56: New in formatVersion 3 compared with 2: -------------
163 *
164 * Resource bundles can optionally use shared string-v2 values
165 * stored in the pool bundle.
166 * If so, then the indexes[] contain two new values
167 * in previously-unused bits of existing indexes[] slots:
168 * - poolStringIndexLimit:
169 * String-v2 offsets (in 32-bit Resource words) below this limit
170 * point to pool bundle string-v2 values.
171 * - poolStringIndex16Limit:
172 * Resource16 string-v2 offsets below this limit
173 * point to pool bundle string-v2 values.
174 * Guarantee: poolStringIndex16Limit <= poolStringIndexLimit
175 *
176 * The local bundle's poolStringIndexLimit is greater than
177 * any pool bundle string index used in the local bundle.
178 * The poolStringIndexLimit should not be greater than
179 * the maximum possible pool bundle string index.
180 *
181 * The maximum possible pool bundle string index is the index to the last non-NUL
182 * pool string character, due to suffix sharing.
183 *
184 * In the pool bundle, there is no structure that lists the strings.
185 * (The root resource is an empty Table.)
186 * If the strings need to be enumerated (as genrb --usePoolBundle does),
187 * then iterate through the pool bundle's 16-bit-units array from the beginning.
188 * Stop at the end of the array, or when an explicit or implicit string length
189 * would lead beyond the end of the array,
190 * or when an apparent string is not NUL-terminated.
191 * (Future genrb version might terminate the strings with
192 * what looks like a large explicit string length.)
193 *
194 * ICU 4.4: New in formatVersion 2 compared with 1.3: -------------
195 *
196 * Three new resource types -- String-v2, Table16 and Array16 -- have their
197 * values stored in a new array of 16-bit units between the table key strings
198 * and the start of the other resources.
199 *
200 * genrb eliminates duplicates among Unicode string-v2 values.
201 * Multiple Unicode strings may use the same offset and string data,
202 * or a short string may point to the suffix of a longer string. ("Suffix sharing")
203 * For example, one string "abc" may be reused for another string "bc" by pointing
204 * to the second character. (Short strings-v2 are NUL-terminated
205 * and not preceded by an explicit length value.)
206 *
207 * It is allowed for all resource types to share values.
208 * The swapper code (ures_swap()) has been modified so that it swaps each item
209 * exactly once.
210 *
211 * A resource bundle may use a special pool bundle. Some or all of the table key strings
212 * of the using-bundle are omitted, and the key string offsets for such key strings refer
213 * to offsets in the pool bundle.
214 * The using-bundle's and the pool-bundle's indexes[URES_INDEX_POOL_CHECKSUM] values
215 * must match.
216 * Two bits in indexes[URES_INDEX_ATTRIBUTES] indicate whether a resource bundle
217 * is or uses a pool bundle.
218 *
219 * Table key strings must be compared in ASCII order, even if they are not
220 * stored in ASCII.
221 *
222 * New in formatVersion 1.3 compared with 1.2: -------------
223 *
224 * genrb eliminates duplicates among key strings.
225 * Multiple table items may share one key string, or one item may point
226 * to the suffix of another's key string. ("Suffix sharing")
227 * For example, one key "abc" may be reused for another key "bc" by pointing
228 * to the second character. (Key strings are NUL-terminated.)
229 *
230 * -------------
231 *
232 * An ICU4C resource bundle file (.res) is a binary, memory-mappable file
233 * with nested, hierarchical data structures.
234 * It physically contains the following:
235 *
236 * Resource root; -- 32-bit Resource item, root item for this bundle's tree;
237 * currently, the root item must be a table or table32 resource item
238 * int32_t indexes[indexes[0]]; -- array of indexes for friendly
239 * reading and swapping; see URES_INDEX_* above
240 * new in formatVersion 1.1 (ICU 2.8)
241 * char keys[]; -- characters for key strings
242 * (formatVersion 1.0: up to 65k of characters; 1.1: <2G)
243 * (minus the space for root and indexes[]),
244 * which consist of invariant characters (ASCII/EBCDIC) and are NUL-terminated;
245 * padded to multiple of 4 bytes for 4-alignment of the following data
246 * uint16_t 16BitUnits[]; -- resources that are stored entirely as sequences of 16-bit units
247 * (new in formatVersion 2/ICU 4.4)
248 * data is indexed by the offset values in 16-bit resource types,
249 * with offset 0 pointing to the beginning of this array;
250 * there is a 0 at offset 0, for empty resources;
251 * padded to multiple of 4 bytes for 4-alignment of the following data
252 * data; -- data directly and indirectly indexed by the root item;
253 * the structure is determined by walking the tree
254 *
255 * Each resource bundle item has a 32-bit Resource handle (see typedef above)
256 * which contains the item type number in its upper 4 bits (31..28) and either
257 * an offset or a direct value in its lower 28 bits (27..0).
258 * The order of items is undefined and only determined by walking the tree.
259 * Leaves of the tree may be stored first or last or anywhere in between,
260 * and it is in theory possible to have unreferenced holes in the file.
261 *
262 * 16-bit-unit values:
263 * Starting with formatVersion 2/ICU 4.4, some resources are stored in a special
264 * array of 16-bit units. Each resource value is a sequence of 16-bit units,
265 * with no per-resource padding to a 4-byte boundary.
266 * 16-bit container types (Table16 and Array16) contain Resource16 values
267 * which are offsets to String-v2 resources in the same 16-bit-units array.
268 *
269 * Direct values:
270 * - Empty Unicode strings have an offset value of 0 in the Resource handle itself.
271 * - Starting with formatVersion 2/ICU 4.4, an offset value of 0 for
272 * _any_ resource type indicates an empty value.
273 * - Integer values are 28-bit values stored in the Resource handle itself;
274 * the interpretation of unsigned vs. signed integers is up to the application.
275 *
276 * All other types and values use 28-bit offsets to point to the item's data.
277 * The offset is an index to the first 32-bit word of the value, relative to the
278 * start of the resource data (i.e., the root item handle is at offset 0).
279 * To get byte offsets, the offset is multiplied by 4 (or shifted left by 2 bits).
280 * All resource item values are 4-aligned.
281 *
282 * New in formatVersion 2/ICU 4.4: Some types use offsets into the 16-bit-units array,
283 * indexing 16-bit units in that array.
284 *
285 * The structures (memory layouts) for the values for each item type are listed
286 * in the table below.
287 *
288 * Nested, hierarchical structures: -------------
289 *
290 * Table items contain key-value pairs where the keys are offsets to char * key strings.
291 * The values of these pairs are either Resource handles or
292 * offsets into the 16-bit-units array, depending on the table type.
293 *
294 * Array items are simple vectors of Resource handles,
295 * or of offsets into the 16-bit-units array, depending on the array type.
296 *
297 * Table key string offsets: -------
298 *
299 * Key string offsets are relative to the start of the resource data (of the root handle),
300 * i.e., the first string has an offset of 4+sizeof(indexes).
301 * (After the 4-byte root handle and after the indexes array.)
302 *
303 * If the resource bundle uses a pool bundle, then some key strings are stored
304 * in the pool bundle rather than in the local bundle itself.
305 * - In a Table or Table16, the 16-bit key string offset is local if it is
306 * less than indexes[URES_INDEX_KEYS_TOP]<<2.
307 * Otherwise, subtract indexes[URES_INDEX_KEYS_TOP]<<2 to get the offset into
308 * the pool bundle key strings.
309 * - In a Table32, the 32-bit key string offset is local if it is non-negative.
310 * Otherwise, reset bit 31 to get the pool key string offset.
311 *
312 * Unlike the local offset, the pool key offset is relative to
313 * the start of the key strings, not to the start of the bundle.
314 *
315 * An alias item is special (and new in ICU 2.4): --------------
316 *
317 * Its memory layout is just like for a UnicodeString, but at runtime it resolves to
318 * another resource bundle's item according to the path in the string.
319 * This is used to share items across bundles that are in different lookup/fallback
320 * chains (e.g., large collation data among zh_TW and zh_HK).
321 * This saves space (for large items) and maintenance effort (less duplication of data).
322 *
323 * --------------------------------------------------------------------------
324 *
325 * Resource types:
326 *
327 * Most resources have their values stored at four-byte offsets from the start
328 * of the resource data. These values are at least 4-aligned.
329 * Some resource values are stored directly in the offset field of the Resource itself.
330 * See UResType in unicode/ures.h for enumeration constants for Resource types.
331 *
332 * Some resources have their values stored as sequences of 16-bit units,
333 * at 2-byte offsets from the start of a contiguous 16-bit-unit array between
334 * the table key strings and the other resources. (new in formatVersion 2/ICU 4.4)
335 * At offset 0 of that array is a 16-bit zero value for empty 16-bit resources.
336 *
337 * Resource16 values in Table16 and Array16 are 16-bit offsets to String-v2
338 * resources, with the offsets relative to the start of the 16-bit-units array.
339 * Starting with formatVersion 3/ICU 56, if offset<poolStringIndex16Limit
340 * then use the pool bundle's 16-bit-units array,
341 * otherwise subtract that limit and use the local 16-bit-units array.
342 *
343 * Type Name Memory layout of values
344 * (in parentheses: scalar, non-offset values)
345 *
346 * 0 Unicode String: int32_t length, UChar[length], (UChar)0, (padding)
347 * or (empty string ("") if offset==0)
348 * 1 Binary: int32_t length, uint8_t[length], (padding)
349 * - the start of the bytes is 16-aligned -
350 * 2 Table: uint16_t count, uint16_t keyStringOffsets[count], (uint16_t padding), Resource[count]
351 * 3 Alias: (physically same value layout as string, new in ICU 2.4)
352 * 4 Table32: int32_t count, int32_t keyStringOffsets[count], Resource[count]
353 * (new in formatVersion 1.1/ICU 2.8)
354 * 5 Table16: uint16_t count, uint16_t keyStringOffsets[count], Resource16[count]
355 * (stored in the 16-bit-units array; new in formatVersion 2/ICU 4.4)
356 * 6 Unicode String-v2:UChar[length], (UChar)0; length determined by the first UChar:
357 * - if first is not a trail surrogate, then the length is implicit
358 * and u_strlen() needs to be called
359 * - if first<0xdfef then length=first&0x3ff (and skip first)
360 * - if first<0xdfff then length=((first-0xdfef)<<16) | second UChar
361 * - if first==0xdfff then length=((second UChar)<<16) | third UChar
362 * (stored in the 16-bit-units array; new in formatVersion 2/ICU 4.4)
363 *
364 * Starting with formatVersion 3/ICU 56, if offset<poolStringIndexLimit
365 * then use the pool bundle's 16-bit-units array,
366 * otherwise subtract that limit and use the local 16-bit-units array.
367 * (Note different limits for Resource16 vs. Resource.)
368 *
369 * 7 Integer: (28-bit offset is integer value)
370 * 8 Array: int32_t count, Resource[count]
371 * 9 Array16: uint16_t count, Resource16[count]
372 * (stored in the 16-bit-units array; new in formatVersion 2/ICU 4.4)

374 * 15 Reserved: This value denotes special purpose resources and is for internal use.
375 *

377 * - Vectors of 8-bit bytes stored as type Binary.
378 * - Vectors of 16-bit words stored as type Unicode String or Unicode String-v2
379 * (no value restrictions, all values 0..ffff allowed!).
380 * - Vectors of 32-bit words stored as type Integer Vector.
