* * eval.c (me_quasilist): New static function.Kaz Kylheku2014-03-251-10/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | (eval_init): Register me_quasilist as quasilist macro expander. * lib.c (quasilist_s): New global variable. (obj_init): quasilist_s initialized. * lib.h (quasilist_s): Declared. * match.c (do_txreval): Handle quasilist syntax. * parser.l (QWLIT): New exclusive state. Extend lexical grammar to transition to QWLIT state upon the #` or #*` sequence which kicks off a word literal, and in that state, piecewise lexically analyze the QLL, mostly by borrowing rules from quasiliterals. * parser.y (QWORDS, QWSPLICE): New tokens. (n_exprs): Integrate splicing form of QLL syntax. (n_expr): Integrate non-splicing form of QLL syntax. (litchars): Propagate line number info. (quasilit): Fix "string literal" wording in error message. * txr.1: Introduced WLL abbreviation for word list literals, cleaned up the text a little, and documented QLL's.
* Introducing word list literals.Kaz Kylheku2014-03-251-0/+40
| | | | | | | | | | | | | | | | * parser.l (WLIT): New exclusive start state. Extend lexical grammar to transition to WLIT state upon the #" or #*" sequence which kicks off a word literal, and in that state, piecewise lexically analyze the literal, mostly by borrowing rules from other literals. * parser.y (WORDS, WSPLICE): New tokens. (n_exprs): Integrate splicing form of word list literal syntax. (n_expr): Integrate non-splicit for of word list literal syntax. (litchars): Propagate line number info.

* * parser.l: Bugfix. When handling a backslash-newline continuationKaz Kylheku2014-03-151-2/+5
| | | | | | | | | | | | | | | | in the SPECIAL, NESTED and BRACED states, do not pop the state in all three, only in SPECIAL (to terminate the @\ continuation). * txr.1: Eliminate wrong claim that string literals do not split across lines, which is directly contradicted two paragraphs later. Document that quasiliterals also split. * genvim.txr (txr_regex, txl_regex): These definitions change from "syn match" to "syn region" so that the backslash-newline continuation can be properly handled. (txr_string, txr_quasilit): Correctly handle split literals. * txr.vim: Regenerated.

| | | | | | | | | | | | | | | * rand.c (make_random_state): Do argument defaulting on seed. Also, mix getpid() into the seed. (random_fixnum): Bugfix: do proper defaulting on optional agument, rather than relying on nil. (random): Fix 2014-02-05 regression. This was totally broken, ignoring the random state passed in and using the global random state. This function must only use the state passed in; there is no defaulting to the global random state. * txr.1: Documenting that seed is optional in make-random-state. Describing what guarantees can be expected with regard to calls made close together temporally.

| | | | | | | | | | Do not throw exceptions for normal process terminations, only for abnormal ones (terminated by a signal). Return the termination status instead of just t. * txr.1: Fixed the neglected documentation of the optional boolean argument of close-stream.

| | | | | | | | | | | | precision (i.e. given by *). The simplest way to do this is to add a state vf_star which is similar to vf_digits, and reuses much of the logic via a goto. Fixing forgotten --fmt (push back char) when moving from vf_precision to vf_spec state due to unhandled character. Also, allowing a leading zero before a precision given as * so that computed precisions can be combined with zero padding. * txr.1: Documented leading zero better so it is clear it combines with *. Restructured documentation.

Recognize the ^ character as a token in the NESTED state. * lib.c (obj_print, obj_pprint): Render sys:qquote as ^. * parser.y (choose_quote): Function removed. (n_expr): Recognize '^' as quasiquote. Removed all the "smart quote" hacks that try to make quote behave as quote or quasiquote, or try to cancel out unquotes and quotes. * tests/009/json.txr: Fixed to ^ quasiquote. * tests/010/reghash.txr: Likewise. * tests/011/macros-2.txr: Likewise. * tests/011/mandel.txr: Likewise. * tests/011/special-1.txr: Likewise. * txr.1: Updated docs. * genvim.txr: Revamped definitions for txr_ident and txl_ident so that unqualified identifiers cannot start with # or ^, but ones with @ or : in front can start with these characters. * txr.vim: Regenerated.

* New quasiquote idea: let's have two quasiquote macros sharing oneKaz Kylheku2014-03-011-29/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | expander. One macro based on sys:qquote, sys:unquote and sys:splice, and the other based on qquote, unquote and splice in the user package. The read syntax puts out the sys: one. * eval.c (expand_qquote): Takes three additional arguments: the qquote, unquote and splice symbols to recognize. The invalid splice diagnostic is adjusted based on which backquote we are expanding. (me_qquote): Look at the symbol in the first position of the form and then expand either the internal quasiquote macro or the public one, passing the right symbols into expand_qquote. (eval_init): Register error-throwing stub functions for the sys_qquote_s, sys_unquote_s and sys_splice_s symbols. Register a macro for sys_qquote_s. * lib.c (sys_qquote_s, sys_unquote_s, sys_splice_s): New symbol variables. (obj_init): Initialize new variables. Change qquote_s, unquote_s and splice_s to user package. (obj_print, obj_pprint): Convert only sys_qquote_s, sys_unquote_s and sys_splice_s to the read syntax. The quote_s, unquote_s and splice_s symbols are not treated specially. * lib.h (sys_qquote_s, sys_unquote_s, sys_splice_s): Declared. * parser.y (n_expr): Use sys_qquote_s, sys_unquote_s and sys_splice_s rather than qquote_s, unquote_s and splice_s. (unquotes_occur): Likewise. * txr.1: Documented.

(expand_macro): If the expander is a cobj, then pull out the C function and call it, otherwise realize the interpreted macro as before. (me_gen, me_delay): New static functions, replace expand_gen and expand_delay. (expand_qquote): Renamed to me_quote. (expand_gen, expand_delay): Renamed to me_gen and me_delay, with an interface adjustment and moved. (expand_op): Renamed to me_op. (expand): Removed qquote, gen, delay, op, and do handling, since these operators are now macros. Removed the unnecessary expansion of with-saved-vars. (reg_op, reg_fun): Assert that the symbol is not nil, to catch initialization order issues. One just showed up: op_do was interned in match.c, which is initialized later. (reg_mac): New static function (eval_init): Intern do_s, because match.c hasn't done it yet at this point. Register me_gen, me_delay, me_op (twice) and me_qquote as intrinsic macros. * txr.1: Documented those operators as macros.

(expand_place): Fix neglect to expand an atomic form, which breaks symbol macros used as places. (expand): Expand symbol macros, expand symacrolet binding forms. Make sure symbol macros are shadowed in the lexical binding constructs. Take advantage of return value of rlcp_tree in a few places. (macro_form_p): Support for symbol macros; bugfix: not handling default argument. (macroexpand_1): Streamlined, and support added for symbol macros. (eval_init): Protect top_smb from gc. Create new hash, stored in top_smb. Initialize defsymacro_s and symacrolet_s. Register op_defsymacro. * parser.y (rlcp_tree): Return the to form instead of useless t and nil. * txr.1: Documented.
