84 | A large part of the code here deals with emulating glibc's reentrant | |
85 | locale API on non-GNU systems. The emulation is a bit "brute-force": | |
86 | Whenever a `-locale<?' procedure is passed a locale object, then: | |
87 | ||
a2f00b9b | 88 | 1. The `scm_i_locale_mutex' is locked. |
b89c4943 | 89 | 2. A series of `setlocale ()' call is performed to store the current |
a2f00b9b | 90 | locale for each category in an `scm_t_locale' object. |
b89c4943 LC |
91 | 3. A series of `setlocale ()' call is made to install each of the locale |
92 | categories of each of the base locales of each locale object, | |
93 | recursively, starting from the last locale object of the chain. | |
94 | 4. The settings captured in step (2) are restored. | |
a2f00b9b | 95 | 5. The `scm_i_locale_mutex' is released. |
b89c4943 | 96 | |
a2f00b9b | 97 | Hopefully, the X/Open standard will eventually make this hack useless. |
b89c4943 LC |
98 | |
99 | Note: We don't wrap glibc's `uselocale ()' call because it sets the locale | |
100 | of the current _thread_ (unlike `setlocale ()') and doing so would require | |
101 | maintaining per-thread locale information on non-GNU systems and always | |
102 | re-installing this locale upon locale-dependent calls. */ | |

1341 | ||
1342 | 1. The `CODESET' value is not normalized. This is a secondary issue, but | |
1343 | still a practical issue. See | |
1344 | http://www.cl.cam.ac.uk/~mgk25/ucs/norm_charmap.c for codeset | |
1345 | normalization. | |
1346 | ||
1347 | 2. `nl_langinfo ()' is not available on Windows. | |
1348 | ||
1349 | 3. `nl_langinfo ()' may return strings encoded in a locale different from | |
1350 | the current one, thereby defeating `scm_from_locale_string ()'. | |
1351 | Example: support the current locale is "Latin-1" and one asks: | |
1352 | ||
1353 | (nl-langinfo DAY_1 (make-locale LC_ALL "eo_EO.UTF-8")) | |
1354 | ||
1355 | The result will be a UTF-8 string. However, `scm_from_locale_string', | |
1356 | which expects a Latin-1 string, won't be able to make much sense of the | |
1357 | returned string. Thus, we'd need an `scm_from_string ()' variant where | |
1358 | the locale (or charset) is explicitly passed. */ | |
