* Clean up srcprops implementationAndy Wingo2020-09-031-11/+10
| | | | | | | | | | | | | | | | | * libguile/deprecated.c (scm_sym_copy, scm_make_srcprops): Deprecate. * libguile/deprecated.h (scm_tc16_srcprops) (SCM_SOURCE_PROPERTY_FLAG_BREAK): Deprecate. * libguile/private-options.h (SCM_COPY_SOURCE_P): Remove. * libguile/read.c (struct t_read_opts, scm_read_options): Remove useless copy read option. (maybe_annotate_source): Change line and column to be tagged, and subtract off lookahead here. Change all callers. (READ_OPTION_COPY_SOURCE_P): Remove, renumbering other options. (init_read_options): Remove copy option. * libguile/srcprop.c: Change to put filename inline in source properties. Update private implementation. * libguile/srcprop.h (SCM_PROCTRACEP): Remove. Unusable given that scm_sym_trace was undefined.
* Update license notices in all C filesAndy Wingo2018-06-201-17/+17
| | | | | Update to newest recommended license notices from the FSF. Everything stays LGPLv3+ except guile-readline which is GPLv3+.
* libguile header files have uniform format for copyright declarationsAndy Wingo2018-06-201-7/+2

* Remove (C) from copyright statementsAndy Wingo2018-06-201-1/+1
| | | | | | As the FSF advises, 'There is no legal significance to using the three-character sequence “(C)”, but it does no harm.' It does take up space though! For that reason, we remove it here from our C files.

* reader options macros incorrect when SCM_ENABLE_ELISP undefinedMichael Gran2010-01-171-3/+6
| | | | | | | | | | When compiled with SCM_ENABLE_ELISP undefined, the reader options macros SCM_R6RS_ESCAPES_P and SCM_SQUARE_BRACKETS_P point past the end of the scm_read_opts struct. *libguile/private-options.h (SCM_R6RS_ESCAPES_P) [!SCM_ENABLE_ELISP]: modified (SCM_SQUARE_BRACKETS_P) [!SCM_ENABLE_ELISP]: modified (SCM_N_READ_OPTIONS): modified
