* SRFI-19: Rename 'tai-epoch-in-jd' to 'utc-epoch-in-jd'.Mark H Weaver2019-06-181-11/+11
| | | | | * module/srfi/srfi-19.scm: Rename 'tai-epoch-in-jd' to 'utc-epoch-in-jd', to reflect its actual meaning and usage.
* Support ~N in SRFI-19 string->dateDaniel Llorens2018-12-111-0/+22
| | | | | | | | * module/srfi/srfi-19.scm (fractional-integer-reader, make-fractional-integer-reader): From reference implementation. (reader-directives): Handle #\N, from reference implementation. * test-suite/tests/srfi-19: Add tests for string->date ~N. * doc/ref/srfi-modules.texi (string->date): Add line for ~N.
* SRFI-19: Minor refactor of leap second table lookups.Mark H Weaver2018-10-241-28/+22
| | | | | | | | | * module/srfi/srfi-19.scm (leap-second-delta): Replace with ... (utc->tai): ... this. (leap-second-neg-delta): Replace with ... (tai->utc): ... this. (current-time-tai, priv:time-tai->time-utc!, priv:time-utc->time-tai!) (time-tai->julian-day, time-monotonic->julian-day): Adapt accordingly.
* SRFI-19: time-utc->date: Support non-integer nanoseconds values.Mark H Weaver2018-10-241-1/+1
| | | | | * module/srfi/srfi-19.scm (time-utc->date): Use 'floor-remainder' instead of 'modulo'.
* SRFI-19: Check for incompatible types in time comparisons.Mark H Weaver2018-10-211-7/+12
| | | | | | | | | | | | Fixes <https://bugs.gnu.org/26163>. Reported by Zefram <zefram@fysh.org>. * module/srfi/srfi-19.scm (time-compare-check): New procedure. (time=?): Use 'time-compare-check' to check the arguments and raise an error in case of mismatched types. Previously, mismatched types would cause time=? to return #f. (time>?, time<?, time>=?, time<=?, time-difference!): Use 'time-compare-check' to check the arguments.
* SRFI-19: Fix normalization of seconds and nanoseconds in time records.Mark H Weaver2018-10-211-18/+16
| | | | | | | | Fixes <https://bugs.gnu.org/26162>. Reported by Zefram <zefram@fysh.org>. * module/srfi/srfi-19.scm (time-normalize!): Rewrite. * test-suite/tests/srfi-19.test: Add tests.
* SRFI-19: Fix handling of negative years and negative julian days.Mark H Weaver2018-10-201-27/+38
| | | | | | | | | | | | | | | | | | | | | | | Fixes <https://bugs.gnu.org/21906>. Mitigates <https://bugs.gnu.org/21903> and <https://bugs.gnu.org/21904>. Reported by: Zefram <zefram@fysh.org>. * module/srfi/srfi-19.scm (encode-julian-day-number) (decode-julian-day-number, date-week-number): Use 'floor-quotient' instead of 'quotient', and 'floor' instead of 'truncate', where appropriate. (time-utc->date): Ensure that the 'nanoseconds' field of the returned date is non-negative. (leap-year): Handle negative years properly, and reformulate the computation. (week-day): Handle negative years properly. Use 'floor-quotient' instead of 'quotient' where appropriate. (directives): In the handler for '~Y' format escapes, improve the handling of years outside of the range 0-9999. (read-directives): Add a FIXME comment to fix the '~Y' reader to handle years outside of the range 0-9999. * test-suite/tests/srfi-19.test: Import (srfi srfi-1). Use Guile's modern keyword notation in the 'define-module' form. Add more tests.

(tai-before-leap-second?): New procedure, derived from upstream SRFI-19. (time-utc->date): Use 'define*' to handle the optional argument. Remove the leap second handling, following upstream SRFI-19. (time-tai->date): Rewrite in terms of 'time-utc->date'. Add special leap second handling, following upstream SRFI-19. (time-monotonic->date): Rewrite in terms of 'time-tai->date'. (date->time-tai, date->time-monotonic): Add special leap second handling, following upstream SRFI-19.

* Complete changing license to LGPLv3+Neil Jerram2009-06-171-1/+1

| | | | | * module/srfi/srfi-19.scm (priv:locale-abbr-weekday->index): Whoops, fix broken manual merge on srfi-19.scm.
* Merge commit 'origin/master' into vmAndy Wingo2009-01-121-1/+1
| | | | | | | | Conflicts: .gitignore guile-tools.in srfi/srfi-19.scm
* avoid delivering 0 values to 1-valued continuations in srfi-19Andy Wingo2008-11-011-16/+11
| | | | | | | | | | | | * module/srfi/srfi-19.scm: Some parts of this code used a strange idiom, `(values)', to indicate that a procedure did nothing. However, quoth R5RS: Except for continuations created by the `call-with-values' procedure, all continuations take exactly one value. Indeed the VM indicated this error. I reworked the code to avoid these cases.
* move scm srfi files to module/srfi, and compile them.Andy Wingo2008-11-011-0/+1491
* .gitignore: Add gdb-pre-inst-guile. * configure.in: Add module/srfi/Makefile. * module/Makefile.am: Add srfi/. * module/srfi/: SRFI scheme files moved here, and compiled. * srfi/Makefile.am: Remove the bits about the scheme files.
