* * genman.txr: Simplify double plass over BODY into single pass.Kaz Kylheku2015-07-032-30/+32
|
* Allow op arguments like @1 to be places.Kaz Kylheku2015-07-032-0/+15
| | | | | | | * share/txr/stdlib/place.tl: Introducing new defplace for (sys:var ...) which is treated as if it were a symbol, in anticipation of the op/do macro placing that syntax with a symbol.
* Support trailing semicolon after hex/octal characters.Kaz Kylheku2015-07-024-6/+47
| | | | | | | | | | | | | | | | * parser.l (%option): Remove nounput option since we need yyunput. (grammar): Rule for matching hex and octal escape in SPECIAL state recognizes optional semicolon. In 109 compatibility, this is pushed back into the stream, otherwise consumed. * txr.1: Updated documentation, including compat notes. * genvim.txr (txr_char): Include optional semicolon in match. Corrected some errors where 8 and 9 were being included as matches for octal digits. (txr_error): Default match for \x or \o not followed by digits.
* Hash-bang support for .tl files.Kaz Kylheku2015-07-026-5/+32
| | | | | | | | | | | | | | | | * parser.c (read_eval_stream): New boolean argument to request hash bang support. * parser.h (read_eval_stream): Declaration updated. * eval.c (sys_load): Pass new thid argument to read_eval_stream, to decline hash bang support. * match.c (v_load): Likewise. * txr.c (txr_main): Request hash bang support from read_eval_stream. Thus files referenced from the txr command line can have a #! line, which is ignored.
* * txr.1: Replace wrong use of .coSSKaz Kylheku2015-07-021-1/+1

* Handle escapes accurately in Vim syntax highlighting.Kaz Kylheku2015-07-022-5/+25
| | | | | | | | | * genvim.txr (txr_badesc, txr_stresc, txr_numesc, txr_regesc): New match categories. (txr_string, txr_quasilit, txr_regex, txl_regex): No longer use skip= argument, but rather contain escape categories. All escapes are colored as Special rather than String, and unknown or malformed escapes are colored as errors.
* * genman.txr: Take advantage of \@ escape in quasilit.Kaz Kylheku2015-07-013-2/+13
| | | | | | | * genvim.txr (txr_escat): New match category containing \@. Colorized a String. (txr_quasilit): Contains txr_escat. Thus, \@ looks like any other escape inside a quasilit.
* * genman.txr: Bugfix: reproduce the correct opening bracketKaz Kylheku2015-07-012-1/+7

* * txr.1: avoid term "regular macro".Kaz Kylheku2015-07-011-2/+2
|
* Fix issues in configure found by ShellCheck.Kaz Kylheku2015-06-272-8/+13
| | | | | | | | * configure (have_timegm, tm_gmtoff, tm_tmzone): Unused variables removed. (SIZEOF_LONG_LONG_T): Reference to nonexistent variable fixed. Also, fixed two instances of arithmetic expressions using unnecessary $ prefixes on variables.
* Fix TXR 97 regression in quasiliterals.Kaz Kylheku2015-06-272-1/+12
| | | | | | | | | * eval.c (expand_quasi): When the modifiers argument of a var item is expanded, the expansion incorrectly places it as the fourth item rather than third. This is effectively a continuation of the incomplete regression fix that was applied on 2014-08-29. The breakage is that `@{(expr) modifier}` ignores modifier whenever (expr) is an expression that undergoes expansion.
* Third round of quasiliteral-related fixes.Kaz Kylheku2015-06-262-5/+13
| | | | | | | | | * parser.l (char_esc): Recognize \@ escape. (grammar): Add a rule for a \@ escape in quasiliterals, and quasi word list literals. * txr.1: Document \@, and remove the lie that @@ encodes for a single @ in quasiliterals.
* Third round of quasiliteral-related fixes.Kaz Kylheku2015-06-262-0/+14
| | | | | | * parser.l (char_esc): Recognize \@ escape. (grammar): Add a rule for a \@ escape in quasiliterals, and quasi word list literals.
* Second round of quasiliteral-related fixes.Kaz Kylheku2015-06-262-1/+17
| | | | | | | | | * parser.l: Only shift to QSPECIAL state when @ is followed by a trailing context consisting of certain characters. Not every kind of Lisp object syntax can be introduced with @ in a quasiliteral. Adding a rule to produce an error when @ appears that is not followed by an allowed character.
* First round of quasiliteral-related fixes.Kaz Kylheku2015-06-263-25/+54
| | | | | | | | | | | | | | | | | | | | | * parser.l: Do not try to recognize floating-point literals in QSPECIAL state; that is not possible because @134.3 in a quasiliteral parses as a METANUM followed by ".3". On the other hand, recognize METANUM literals in QSPECIAL state, so that @@123 scans. Recognize @ as a token in QSPECIAL state, so @@abc will scan. When transitioning from QSILIT and QWLIT states to QSPECIAL upon scanning @, return a @ token, which is now parsed in the grammar. * parser.y (quasi_meta_helper): New static function. (q_var): Do not handle SYMTOK any more, only the braced variable syntax. SYMTOK is handled as a n_expr. Braced vars are handled with explicit '@' token, which is now produced by the scanner when it shifts from QSILIT to QSPECIAL. (quasi_item): No longer necessary to recognize various forms here such as quotes and splices. Just recognize a n_expr, preceded by '@'.
