* command line: support -f in Hash Bang Null Hack.Kaz Kylheku2019-01-281-0/+58
| | | | | | | | | | | | * txr.c (txr_main): In processing the -f option, if there is already an input source, but its name exactly matches the argument of the -f option, then ignore the -f and its option intead of terminating with a diagnostic. This allows the user to use -f in the Null Hack to achieve the usual trick of allowing the script to take options passed through to the interpreter. * txr.1: Documented.
* Version 207.txr-207Kaz Kylheku2019-01-261-3/+3
| | | | | | | | * RELNOTES: Updated. * configure, txr.1: Bumped version and date. * share/txr/stdlib/ver.tl: Likewise.
* doc: review of Lisp CompilationKaz Kylheku2019-01-201-3/+14
| | | | | | | | * txr.1: eval mistakenly referred to instead of compile-file under Compile File. Spurious pluralization of literals fixed. New "Bound symbols in dwim" heading to separate text from discussion of unbound symbols in dwim. Clarifying text added about compile-toplevel's treatment of form.

* carray: fix vec/list conversion bug.Kaz Kylheku2019-01-171-1/+1
| | | | | | | | | | | | | | | | | | | | If a zero-length carray is converted with vec-carray or list-carray and the null-term-p argument is t, there is an exception about a negative index. An empty vector or list should be returned in this case, and the documentation says exactly that. Also, if a carray of unknown length is converted, there is an exception from vec-carray, as documented, but it's an uninformative one that is incidentally produced when -1 is passed to the vec function. The list-carray just returns nil, contravening the documentation. * ffi.c (vec_carray, list_carray): Fix the problems described above. * txr.1: Reviewing the documentation for these functions, an improperly terminated sentence was found.

* doc: formatting under lop.Kaz Kylheku2018-12-241-2/+2
| | | | | | * txr.1: Closing quote didn't come out in .codn; we must use the \(dq code in this context. Let's make the opening quote \(dq also for consistency.

* doc: caseql* macro expands cases in global envKaz Kylheku2018-11-271-1/+1
| | | | | | * txr.1: Use the correct term "global environment" rather than "dynamic environment" to desribe the scope in which caseq*, caseql* and casequal* expand the key forms.
* doc: avoid "empty lexical environment".Kaz Kylheku2018-11-271-4/+5
| | | | | | | | | * txr.1: Replace the term "empty lexical environment" with "global environment" in a few places. In one case, it is removed, and the surrounding wording is adjusted. The "empty lexical environment" term is poor because the situations which it describes retain visibility of the "global lexical" variables.
* doc: clarify pretty printing.Kaz Kylheku2018-11-251-3/+34
| | | | | * txr.1: adding more details to description of the effect of pretty printing.
* print: keep colon in keyword symsKaz Kylheku2018-11-251-1/+9
| | | | | | | | * lib.c (obj_print_impl): Always include leading colon when printing keyword symbols, regardless of pretty flag. Subject to backward compatibility. * txr.1: Compat note added.
* doc: refresh documentation of make-lazy-consKaz Kylheku2018-11-251-8/+34
| | | | | | * txr.1: Documentation of make-lazy-cons revised with important clarifications and details, and removal of some overly informal language.
* logxor: fix seriously broken function.Kaz Kylheku2018-11-251-0/+7
| | | | | | | | | | | | | Reported by Guillaume le Vaillant. * arith.c (logxor): Fix broken behavior when the arguments are the same nonzero fixnum, or the same bignum object. (logxor_old): New function: verbatim copy of previous logxor. * eval.c (eval_init): Register logxor intrinsic to the broken function if compatibility is 202 or less. * txr.1: Compat note added.
* Version 202.txr-202Kaz Kylheku2018-11-221-2/+2

* doc: clarify delimited continuation compiled semanticsKaz Kylheku2018-11-181-10/+30
| | | | | | | | | | * txr.1: Text describing the changes in behavior, under delmited continuations, of compiled code that mutates variables seemed unclear; it is revised. Also, in the section that discusses compiled versus interpreted differences under Lisp Compilation, a paragraph is added mentioning delimited continuations, referring the reader to this detailed section.
* doc: move functionpKaz Kylheku2018-11-171-14/+14
| | | | | * txr.1: functionp belongs under Functions, not Global Environment.
* doc: use bulleted list under copy.Kaz Kylheku2018-11-171-56/+29
| | | | | * txr.1: Present the type cases of the copy function using a more compact and visually appealing bulleted list.
* copy: call copy-fun for functions.Kaz Kylheku2018-11-171-0/+6
| | | | | | * lib.c (copy): Handle FUN type through copy_fun. * txr.1: Documented.
* compile: handle functions that have environments.Kaz Kylheku2018-11-131-0/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With this patch, the compile function can handle interpreted function objects that have captured environments. For instance, if the following expression is evaluated (let ((counter 0)) (labels ((bm () (bump)) (bump () (inc counter))) (lambda () (bm)))) then a function object emerges. We can now feed this function object to the compile function; the environment will now be handled. Of course, the above expression is already compileable; compile-toplevel handles it and so does the file compiler. This patch allows the expression to be interpreted and then the function object to be compiled, without access to the surrounding expression. The compiled function will contain a compiled version of the environment, carrying compiled versions of the captured variables and their contents. * eval.c (env_vbindings, env_fbindings, env_next): New static functions. (eval_init): Register env-vbinding, env-fbindings and env-next intrinsics. * share/txr/stdlib/compiler.tl (sys:env-to-let): New function. (usr:compile): Wrap the interpreted lambda terms with let bindings carefully reconstructed from their captured environments. * txr.1: Documented new intrinsic functions.
* copy-fun: duplicate a function, with own environment.Kaz Kylheku2018-11-131-0/+36
| | | | | | | | | | | | | | | | | * eval.c (deep_copy_env): New function. (eval_init): Register copy-fun intrinsic. * eval.h (deep_copy_env): Declared. * lib.c (copy_fun): New function. * lib.h (copy_fun): Declared. * vm.c (vm_copy_closure): New function. * vm.h (vm_copy_closure): Declared. * txr.1: Documented copy-fun.
* doc: corrections under Referencing DotKaz Kylheku2018-11-111-6/+9
| | | | | * txr.1: Don't start sentence with And. Revise and correct description of associativity of referencing dot.
* doc: changes to introKaz Kylheku2018-11-111-27/+39
| | | | | | * txr.1: Substantially revising introductory paragraphs. Mentioning compiling and stand-alone application deployment. Mention licensing freedom.
* doc: listener suspend doesn't "depend" on job controlKaz Kylheku2018-11-111-2/+6
| | | | | | | * txr.1: Revise wording implying that the Ctrl-Z suspend depends on POSIX job control. Job control is required for it to allow TXR to be foregrounded after it suspends. That is not our problem.
* doc: listener: remove irrelvant historic notesKaz Kylheku2018-11-111-9/+2
| | | | | | * txr.1: In descriptions of multi-line mode, remove notes about behavior changes between TXR 178 and 179. This doesn't affect TXR program and is probably of no interest to anyone.
* doc: fixes under Null Hack description.Kaz Kylheku2018-11-111-9/+11
| | | | | * txr.1: Fix awkward wording about env's dispatch of txr, and references to wrong user name in examples.
* Version 201.Kaz Kylheku2018-11-071-3/+3
| | | | | | | | | | * RELNOTES: Updated. * configure, txr.1: Bumped version and date. * share/txr/stdlib/ver.tl: Likewise. * txr.vim, tl.vim: Regenerated.
