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) |

351 | * 3 Alias: (physically same value layout as string, new in ICU 2.4) |

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. |
