* txr: @(eof) takes argument for binding termination status.Kaz Kylheku2021-08-051-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | We extend the matching context structures to keep track of the underlying stream from which lines are being taken via the lazy list. Then the implementation of the @(eof) directive, when it hits the eof condition, can use this stream to gain access to the termination status. * match.c (match_line_ctx, match_files_ctx): New member, stream. (ml_all): Take stream argument and initialize new member. (h_call, do_match_line): Pass stream argument to h_call. (mf_all, mf_file_data): Take stream argument and initialize new member. (mf_from_ml): Propagate stream from line context to file context. (freeform_prepare, v_next_impl, match_filter, match_fun, extract): Pass stream argument where now needed. (v_eof): Implement termination status binding via the stream stored in the context. (open_data_source): Store stream in match files context. * tests/010/eof-status.txr: New file. * tests/010/eof-status.expected: New file. * Makefile (tst/tests/010/eof-status.ok): -B option for new test. * txr.1: Documented eof directive, argument and all. * stdlib/doc-syms.tl: Updated.
* doc: reproducible PDF.Kaz Kylheku2021-07-171-0/+1
| | | | | | | * Makefile (txr-manpage.pdf): If SOURCE_DATE_EPOCH exists, then run pdf-clobber-stamps.tl. * pdf-clobber-stamps.tl: New file.
* build: recompile txr.c if build_id changes.Kaz Kylheku2021-07-141-2/+9
| | | | | | | | | | | | | | | | | | With this change, it is possible to make build_id=abcd to rebuild TXR with the given build ID. Any changes in the value of a dynamic, git-generated build_id will likewise trigger a rebuild. * Makefile (old_build_id): New variable. We read the old build ID from a file called .build_id in the build directory. If it differs from the current expanded ID, build_id_exp, we remove the object files affected by build_id. In all cases, we then write the current build ID into the .build_id file. (clean, distclean): Remove .build_id.
* tests: .txr tests can skip using exit code 13.Kaz Kylheku2021-07-121-5/+6
| | | | | * Makefile (tst/%.ok): If a .txr test terminates with status 13, that indicates that it should be skipped.
* New: build-id feature.Kaz Kylheku2021-07-111-0/+3
| | | | | | | | | | | | | | | | | | | | | | A build-id is a string optionally embedded into TXR at build time which can be displayed with a command line option. It can help developers who are juggling multiple builds in their workspace to identify what they are running. * Makefile (txr.o, txr-win.o): If a build_id has been defined, then define the TXR_BUILD_ID macro on the command line when compiling these object files. * configure (build_id): New variable. (help) Describe build_id. (gen_config_make): Generate build_id and build_id_exp make variables. * txr.1: Documented --build-id option. * tsr.c (build_id): Conditionally defined global variable. (help): Brief help string for --build-id. (txr_main): Process --build-id option.
* build: update some targets.Paul A. Patience2021-07-051-10/+15
| | | | | | | | | | | | * Makefile (tainted): Fix typo. Reword sentence. (rebuild): Remove obsolete references to repatch target. (clean, distclean): Remove tst directory. Separate directory removals from file removals. Remove txr-manpage.html and txr-manpage.pdf in both distclean targets. In non-configured distclean, correct the removal of .tlo files to be from the stdlib directory rather than from share (and limit the pattern to *.tlo rather than *.tlo*, since .tlo2 files are no longer generated); and explicitly remove config.h and config.make, just like the configured distclean.
* install-tests: use relative path in run.sh.Kaz Kylheku2021-06-241-1/+1
| | | | | | | | * Makefile (install-tests): In the generated run.sh, let's allow flexibility in the installation location of the tests by avoiding a cd to an absolute path where the tests are assumed to be installed. Let's assume that they are installed relative to where the run.sh script is, and cd there.
* file layout: moving share/txr/stdlib to stdlib.Kaz Kylheku2021-06-241-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This affects run-time also. Txr installations where the executable is not in directory ending in ${bindir} will look for stdlib rather than share/txr/stdlib, relative to the determined installation directory. * txr.c (sysroot_init): If we detect relative to the short name, or fall back on the program directory, use stdlib rather than share/txr/stdlib as the stdlib_path. * INSTALL: Update some installation notes not to refer to share/txr/stdlib but stdlib. * Makefile (STDLIB_SRCS): Refer to stdlib, not share/txr/stdlib. (clean): In unconfigured mode, remove the old share/txr/stdlib entirely. Remove .tlo files from stdlib. (install): Install lib materials from stdlib. * txr.1: Updated documentation under Deployment Directory Structure. * share/txr/stdlib/{asm,awk,build,cadr}.tl: Renamed to stdlib/{asm,awk,build,cadr}.tl. * share/txr/stdlib/{compiler,conv,copy-file,debugger}.tl: Renamed to stdlib/{compiler,conv,copy-file,debugger}.tl. * share/txr/stdlib/{defset,doc-lookup,doc-syms,doloop}.tl: Renamed to stdlib/{defset,doc-lookup,doc-syms,doloop}.tl. * share/txr/stdlib/{each-prod,error,except,ffi}.tl: Renamed to stdlib/{each-prod,error,except,ffi}.tl. * share/txr/stdlib/{getopts,getput,hash,ifa}.tl: Renamed to stdlib/{getopts,getput,hash,ifa}.tl. * share/txr/stdlib/{keyparams,match,op,optimize}.tl: Renamed to stdlib/{keyparams,match,op,optimize}.tl. * share/txr/stdlib/{package,param,path-test,pic}.tl: Renamed to stdlib/{package,param,path-test,pic}.tl. * share/txr/stdlib/{place,pmac,quips,save-exe}.tl: Renamed to stdlib/{place,pmac,quips,save-exe}.tl. * share/txr/stdlib/{socket,stream-wrap,struct,tagbody}.tl: Renamed to stdlib/{socket,stream-wrap,struct,tagbody}.tl. * share/txr/stdlib/{termios,trace,txr-case,type}.tl: Renamed to stdlib/{termios,trace,txr-case,type}.tl. * share/txr/stdlib/{ver,vm-param,with-resources,with-stream}.tl: Renamed to stdlib/{ver,vm-param,with-resources,with-stream}.tl. * share/txr/stdlib/yield.tl: Renamed to stdlib/yield.tl. * share/txr/stdlib/{txr-case,ver}.txr: Renamed to stdlib/{txr-case,ver}.txr. * gencadr.txr: Update to stdlib/place.tl. * genman.txr: Update to stdlib/cadr.tl.
* build: improved mechanism for copying .shipped files.Kaz Kylheku2021-06-011-3/+9
| | | | | | | | | | | * Makefile (SHIPPED): New variable, holds names of files that get copied to a .shipped suffix and commited to the repo. (ABBREV3SH): New macro, version of ABBREV3 that doesn't assume it is expanding an entire recipe line, and thus can be embedded into shell commands. (%.shipped): Rule removed. (shipped): New rule that prints what it is copying. Non-maintainer version of rule errors out.
* build: produce output when copying .shipped files.Kaz Kylheku2021-06-011-0/+1
| | | | | | | | | * Makefile (%.shipped): Call the ABBREV macro to produce output when "make *.shipped" is invoked, otherwise unless VERBOSE=1 is used, it works silently. This is only in maintainer mode. The rule in regular mode has the ABBREV call. (But should we have that rule at all outside of maintainer mode?)
* tests: implicitly generate empty .expected files.Kaz Kylheku2021-04-121-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Makefile (%.expected): New implicit rule. Whenever a test requires a .expected file, if it is missing, we create an empty one. This file will be treated as an intermediate by GNU Make, which means that it will be deleted when make terminates. * tests/012/compile.tl: Some of the .tl files no longer have an .expected file, so we have to test for that in the catenating logic. * tests/008/call-2.expected, * tests/008/no-stdin-hang.expected, * tests/011/macros-3.expected, * tests/011/patmatch.expected, * tests/012/aseq.expected, * tests/012/ashwin.expected, * tests/012/compile.tl, * tests/012/cont.expected, * tests/012/defset.expected, * tests/012/ifa.expected, * tests/012/oop-seq.expected, * tests/012/parse.expected, * tests/012/quasi.expected, * tests/012/quine.expected, * tests/012/seq.expected, * tests/012/struct.expected, * tests/012/stslot.expected, * tests/014/dgram-stream.expected, * tests/014/in6addr-str.expected, * tests/014/inaddr-str.expected, * tests/014/socket-basic.expected, * tests/015/awk-fconv.expected, * tests/015/split.expected, * tests/015/trim.expected, * tests/016/arith.expected, * tests/016/ud-arith.expected, * tests/017/ffi-misc.expected, * tests/018/chmod.expected: Empty file deleted.
* build: calm restless yacc.Kaz Kylheku2021-04-081-6/+1
| | | | | | | | | | * Makefile (%.tab.c %.tab.h): Remove the trick of keeping the old y.tab.h file if it has not changed. This was once a good idea, but now that we have a proper grouped targets pattern rule which knows that y.tab.h depends on and is produced from parser.y, the trick causes y.tab.h to be perpetually out of date due to its old time stamp, and so yacc is run on every build.
* M1: Fix sed issue.Kaz Kylheku2021-03-241-1/+5
| | | | | | | | | | | | | | | | | The MacOS sed doesn't accept semicolon termination for commands involving defining labels or branching to labels. This is not a new issue, but it is revealed on newer MacOS because the sed now complains about unused labels. In the sed command ':x; /whatever/ { ...; tx }', everything after the initial : is interpreted as a label. * Makefile (DEPGEN): Split the sed command's syntax up into logical lines using multiple -e commands, applying some formatting with indentation to try to keep it readable. It looks like multiple -e options just glue together to make a program, as if they were lines of code; one -e can define a label referenced by another, and even the closing brace can be treated as a separate command.
* build: use yacc pattern rule with "y" as stem.Kaz Kylheku2021-03-221-9/+1
| | | | | | | | | | | | | | | | Thanks to a recent discussion in the GNU Make mailing list about some issue related to grouped patterns, I hit upon the realization that the rule y.tab.h y.tab.c: parser.y has a common stem, y, which can be exploited to write a pattern rule. This is only active in maintainer mode; in user mode, the y.tab.h and y.tab.c are separately produced from .shipped files. * Makefile (y.tab.h): Eliminate rule which detects a removed y.tab.h. (y.tab.c): Delete rule, replacing with new rule. (%.tab.c %.tab.h): New pattern rule, which groups the targets together.
* tests: fix retest logic for parallel operation.Kaz Kylheku2021-03-161-7/+5
| | | | | | | | | I'm giving up and just using a recursive make invocation for the "retest" target. * Makefile (retest): Depend on nothing. Remove the tst directory and invoke make tests recursively. (tests.clean): Target removed.
* build: cautiously allow parallel builds.Kaz Kylheku2021-03-011-4/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Over two years ago, I disabled parallel building with a .NOTPARALLEL: directive in the Makefile, due to some rules that depended on order of updates of their prerequisites. Today the situation is better. It looks like there are just a few rules that have to be fixed, all in the area of executing tests. Let us not enable that by default, though, to protect downstream users from themselves. Some operating system distribution builds optimistically run make -j N on all the packages, and then have to deal with sporadic breakages when some of those packages have parallel build bugs. We can prevent TXR from ever being implicated in such a breakage by turning off parallel building even if make -j requests it. There will now be a ./configure --parallelmake option to allow parallel builds, off by default. The --maintainer configuration mode will flip that default; configuring in maintainer mode will enable parallel builds, unless explicitly disabled with --no-parallelmake. * Makefile (.NOTPARALLEL): Conditionally assert, if parallelmake is false. (tst/tests/014/dgram-stream.ok, tst/tests/014/socket-basic.ok): Enforce order between these two tests. They clash in their use of network ports so cannot run at the same time. (test.clean): test.clean must finish executing before tests; enforce order. * configure (parallelmake, parallelmake_given): New variables. (help text): Add parallelmake option to help. (gen_config_make): Generate the parallelmake make variable into config.make. New script section, defaulting parallelmake to y in maintainer mode.
* txr: pattern function calls are non-matching.Kaz Kylheku2021-02-211-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch causes TXR to treat calls to verticatl functions, as well as the @(call) directive to be considered non-matching directives, so that opening the data source is deferred. This allows included .txr files to call the funtions that they define, without the side effect of standard input being read. * match.c (open_data_source): Function refactored to reduce duplication. c->data is checked first, and if it is not t, nothing is done, making the function cheaper in the frequent case. The non_matching_dir condition changes. We now check that the first element of the first spec is a non-nil symbol. If it has a function binding as a vertical function, then that is considered non_matching. (dir_tables_init): Treat @(call) as a non-matching directive. * Makefile (tst/tests/008/no-stdin-hang.ok): Add -n argument for non-interactive, which will cause stdin to be read in that test case if there is a regression in this change. If make tests is run in a terminal, this will hang make tests. * tests/no-stdin-hang.txr: New file. * tests/no-stdin-hang.expected: New file.
* @(rebind): bugfix: don't clobber right side variable.Kaz Kylheku2021-01-301-0/+1
| | | | | | | | | | | | | | | | | | | | | * Makefile (tst/tests/000/binding.ok): Pass -B to txr for this new test. * match.c (v_rebind): Fix gaping copy-and-paste bug here, which causes rebind to take on the behavior of local/forget; it takes all symbols that appear as its arguments from the environment and produces an environment in which they don't exist. What we want is to remove the left variables from the environment, and since that is a nested pattern, the right way to do that is to flatten it. Bug reported by Frank Schwidom. * tests/000/binding.txr: New file. * tests/000/binding.expected: New file. * txr.1: Improve documentation of @(rebind), also making improvements in @(set) documentation.
* build: add rule for updating .shipped material.Kaz Kylheku2021-01-241-0/+3
| | | | * Makefile (%.shipped): New pattern rule.
* build: support linker flags/libs separation.Kaz Kylheku2021-01-141-6/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Our build system lumps all linker options together. The correct way is that linker flags are separated info flags and libs. Also, we respond to the LDFLAGS variable but ignore LDLIBS which is incorrect. Other issues are fixed. All that is fixed here. * Makefile (TXR_CFLAGS): Interpolate $(CFLAGS) last, so that options coming from CFLAGS can override previous options. (TXR_LDFLAGS): Interpolate $(LDFLAGS) last; same reason. (TXR_LDLIBS): New variable. (LINK_PROG): Put $(TXR_LDFLAGS) with the options, before the -o, and put $(TXR_LDLIBS) at the end. * configure (conf_ldlibs, platform_ldlibs): New variables. (usage text): Document platform-ldlibs and adjust documentation of platform-ldflags. (gen_config_make): Generate PLATFORM_LDLIBS and CONF_LDLIBS now needed by Makefile. (mainline): Adjusts various recipes to use conf_ldlibs instead of conf_ldflags, or in some cases both. In the case of libffi where we use pkg-config, we use the special pgk-config options to separately extract the flags and libs. We use EXTRA_LDLIBS instead of EXTRA_LDFLAGS in some conftest invocations, as necessary.

* build: Android support.Kaz Kylheku2020-12-231-0/+6
| | | | | | | | | | * Makefile (conftest.android): New helper target for testing for Android toolchain, via presence of __ANDROID__ preprocessor symbol, similarly to how we detect Darwin. * configure: New test for Android. This is mutually exclusive agains Darwin. On Android, we add some necessary feature selection macros to the compiler command line.
* configure: replace nm-based trick for sizesKaz Kylheku2020-10-091-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | The trick of declaring static arrays whose size is the value of an integer is not working with newer gcc 10 on Cygwin, because that compiler is rearranging the order of the arrays and adding padding. Basically, the writing on the wall is that this is not a good approach. I'm switching to a different approach. By initializing a suitable C structure (which contains character arrays) in a particular way, we can create a .o file in which a shell script is embedded. We can pull out the shell script and evaluate it to get the sizes of types. * Makefile (conftest.syms): Rule removed. (conftest.clean): Don't remove conftest.syms. * configure (conftest_syms, read_syms): Functions removed. (LANG, LC_ALL): New environment variables. This is needed because we are using tr to process a binary file; we can't have it trying to decode multi-byte characters. (mainline): Use new trick for obtaining variables like SIZEOF_INT.

If the yacc program is detected as Bison, check for version 2.5 and fail if not found.
* parser: commit Bison-2.5-generated code.Kaz Kylheku2020-09-241-11/+8
| | | | | | | | | | | | | * Makefile (BS_LIC_FROM, BS_LIC_TO): Variables removed. (y.tab.c): Remove all filtering hacks. Don't remove the license from y.tab.c. Don't remove yyparse declaration from y.tab.h. Provide a pattern rule for producing any missing file X from X.shipped. That's how y.tab.c and y.tab.h get produced from y.tab.c.shipped and y.tab.h.shipped, respectively, in user mode. * y.tab.c.shipped, y.tab.h.shipped: New files, generated using Bison 2.5.
* new: maintainer mode.Kaz Kylheku2020-09-241-0/+4
| | | | | | | | | | | | | | | | | | There is now a ./configure --maintainer mode which establishes a variable called maintainer in config.make, with a y value. The initial use for maintainer mode will be that the Yacc parser (the y.tab.c and y.tab.h) files will no longer be regenerated whenever the parser.y file is newer. In the following commit, I will add a generated parser. * Makefile (y.tab.h, y.tab.c): These rules are now only enabled in maintainer mode via an ifeq. * configure (maintainer): New variable. (gen_config_make): Generate maintainer make variable definition in config.make.
* Makefile: stray tabs.Kaz Kylheku2020-09-241-1/+1

* New tests for chmod.Kaz Kyheku2020-02-071-0/+2
| | | | | | | | | | | | | | | | The chmod fixes in the previous several commits were caught by this. * Makefile (tst/tests/018/chmod.ok): Set up TXR_ARGS for this test to give it the location of the temporary file to use as the object for testing permissions. (tst/tests/018): Disable TXR_DBG_OPTS for new directory. * tests/018/chmod.tl: New file. * tests/018/chmod.expected: Likewise. * tests/perm.tl: Likewise.
* build: drop config.log in favor of reconfigureKaz Kyheku2020-01-291-2/+2
| | | | | | | | | | | | | | | | | | | | | | | The configure command line is now turned into an executable script called reconfigure which can be invoked to repeat the config. * Makefile (distclean): Whether in a configured or state or not, try to remove reconfigure. In the configured state, don't remove config.log. (If distclean is invoked when not configured, the config.* pattern will remove config.log). * configure: rewrite the logic which turns the command line into text. It is now robust against spaces, quotes and meta-charaters. Moreover, the printed representation is chosen according to good heuristics to minimize unnecessary quoting and escaping. The config line is written into an executable script called reconfigure. This is now done twice; it is done immediately, so that we save the command line even if the configure subsequently fails. A comment is added to reconfigure indicating that configure didn't succeed. Then after a successful run through the tests, we save it again, without the cautionary comment. Help texts updated.
* build: deal with the mess of new Bison warnings.Kaz Kylheku2020-01-101-1/+11
| | | | | | | | | | | | | | | | | | | | | | | | Newer versions of Bison produce spurious warnings in Yacc mode about %pure-parser being not POSIX conforming and also deprecated. Plus some strange fluff about "fix-its" that can be applied if option --update is specified. Let's detect at configure time whether the Yacc program being used is actually Bison 3.0 or greater, and if so, give it some flags to shut up these warnings. * Makefile (YACC_FLAGS): New variable, conditionally set based on yacc_is_newer_bison, also new variable, that being generated into config.make. (y.tab.c): Invoke $(TXR_YACC) with $(YACC_FLAGS). (conftest.yacc-version): New phony target for running Yacc with --version, out of the configure script. * configure (yacc_is_newer_bison): New variable. (gen_config_make): Generate yacc_is_newer_bison make variable. New test for whether Yacc is Bison. If so, and the version is >= 3.0, sets the yacc_is_newer_bison variable to y.

* New data type: tnode.Kaz Kylheku2019-09-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Binary search tree nodes are being added as a basic heap data type. The C type tag is TNOD, and the Lisp type is tnode. Binary search tree nodes have three elements: a key, a left child and a right child. The printed notation is #N(key left right). Quasiquoting is supported: ^#N(,foo ,bar) but not splicing. Because tnodes have three elements, they they fit into TXR's four-word heap cell, not requiring any additional memory allocation. These nodes are going to be the basis for a binary search tree container, which will use the scapegoat tree algorithm for maintaining balance. * tree.c, tree.h: New files. * Makefile (OBJS): Adding tree.o. * eval.c (expand_qquote_rec): Recurse through tnode cells, so unquotes work inside #N syntax. * gc.c (finalize): Add TNOD to no-op case in switch; tnodes don't require finalization. (mark_obj): Traverse tnode cell. * hash.c (equal_hash): Add TNOD case. * lib.c (tnode_s): New symbol variable. (seq_kind_tab): New entry for TNOD, mapping to SEQ_NOTSEQ. (code2type, equal): Handle TNOD. (obj_init): Initialize tnode_s variable. (obj_print_impl, populate_obj_hash): Handle TNOD. (init): Call tree_init function in tree.c. * lib.h (enum type, type_t): New enumeration TNOD. (struct tnod): New struct type. (union obj, obj_t): New union member tn of type struct tnod. (tnode_s): Declard. * parserc.c (circ_backpatch): Handle TNOD, so circular notation works through tnode cells. * parser.l (grammar): Recognize #N prefix, mapping to HASH_N token. * parser.y (HASH_N): New grammar terminal symbol. (tnode): New nonterminal symbol. (i_expr, n_expr): Add tnode cases to productions. (yybadtoken): Map HASH_N to "#N" string.
* build: clean target should remove run.shKaz Kylheku2019-09-091-2/+2
| | | | | * Makefile (clean): If it exists, remove the temporary run.sh that is generated by the install-tests target.
* build: bugfix: compiler opts duplicated; remove_flags broken.Kaz Kylheku2019-08-251-1/+1
| | | | | | * Makefile (TXR_CFLAGS): Use := operator rather than += when filtering out REMOVE_FLAGS, or else REMOVE_FLAGS are not really removed, and we duplicate all the flags.
* New: MD5 digest functions.Kaz Kylheku2019-08-231-1/+1
| | | | | | | | | | | | | | | | | * Makefile (OBJS): New object file, chksums/md5.o. * chksum.c (sha256_ensure_buf): Renamed to chksum_ensure_buf and made generic so MD5 code can borrow it. (sha256_stream, sha256): Call chksum_ensure_buf instead of sha256_ensure_buf, passing in new length and hash name parameters. (md5_stream_impl, md5_buf, md5_str): New static functions. (md5_stream, md5): New functions. (chksum_init): Register md5-stream and md5 intrinsics. * chksum.h (md5_stream, md5): Declared. * chksums/md5.c, chksums/md5.h: New files.
* tests: add test related to recent @(collect) change.Kaz Kylheku2019-08-121-0/+2
| | | | | | | | | | | This test will misbehave on TXR without the previous fix; it will not collect columns of data which keep the corresponding rows items together. * tests/002/variant, tests/002/variant.expected, tests/002/variant.txr: New files. * Makefile (TXR_ARGS, TXR_OPTS): Override for new test.
* tests: add @{var1 var2} match test.Kaz Kylheku2019-07-031-0/+1
| | | | | | | | | | | | | | * tests/001/query-5.txr: New file. * tests/001/query-5.expected: New file. * Makefile (tst/tests/001/query-5.ok): Pass -B to txr for this new test. * tests/017/glob-carray.expected: Updated, because the glob test globs over the contents of tests/001 directory. * tests/017/glob-zarray.expected: Likewise.
* New: CRC-32 functions.Kaz Kylheku2019-06-241-1/+1
| | | | | | | | | | | | * Makefile (OBJS): Add chksums/crc32.o. * chksum.c (crc32_stream, crc32): New functions. (chksum_init): Register crc32-stream and crc32 intrinsic functions. * chksums/crc32.c, chksums/crc32.h: New files. * txr.1: Documented.
* * Makefile (OBJS): New objects chksum.o and chksums/sha256.o.Kaz Kylheku2019-06-231-1/+1
| | | | | | | | | | * chksum.c, chksum.h, chksums/sha256.c, chksums/sha256.h: New files. * lib.c (init): Call chksum_init. * txr.1: Documented. * LICENSE: Add SHA-256 copyright notice.
* Makefile: non-configured distclean removes tlo's.Kaz Kylheku2019-06-121-1/+1
| | | | | | * Makefile (distclean): distclean target for not-configured state removes .tlo files by wildcard, including the old .tlo2 files that we used to generate once.
* build: allow $(pwd)/configure to work.Kaz Kylheku2019-04-291-1/+1
| | | | | | | | | | | | | | | | | | | | | When the build is being done in the source directory, allow the configure script to be executed via path names other than just ./configure, such as an absolute path. Some distros use this. * configure (build_in_srcdir): New variable. (inode): New function. Rather than checking whether "$source_dir" is ".", we test whether they are the same inode. If they are the same, we now also set the build_in_srcdir variable in addition to generating the usual warning. (gen_config_make): Propagate the build_in_srcdir into config.make. * Makefile: use the build_in_srcdir variable from config.make to determine whether we are building in the source directory, rather than relying on top_srcdir being blank.
* build: remove nonexistent config option.Kaz Kylheku2019-02-261-2/+2
| | | | | | * Makefile (dbg/%-win.o, opt/%-win.o): Don't pass CONFIG_WIN_MAIN=1 preprocessor symbol; it's not referenced anywhere, and never has been.
* build: get rid of .tlo2 files.Kaz Kylheku2019-02-081-12/+3
| | | | | | | | | | | | | | | After the defvar bugfix in the previous commit, the only differences between .tlo and .tlo2 files are the names of a few gensyms here and there. In other words, they are identical code; therefore, there is no point in compiling them. * Makefile (STDLIB_TLOS2): Variable removed. (%.tlo2): Implicit rule removed. (stage1 stage2): Phony targets removed. (all): Directly depends on $(STDLIB_TLOS) without stage1 intermediary. (clean-tlo): Don't remove $(STDLIB_TLOS2).
* install: broken when using separate build dir.Kaz Kylheku2019-01-251-2/+1
| | | | | | | | * Makefile (install): Drop the $(top_srcdir) prefix from share/txr/stdlib materials. This fails for the .tlo files which are only found in the build directory, not the source directory. The .txr and .tl files are found in both, thanks to symlinks; for those it works either way.
* mpi: remove unused mplogic module.Kaz Kylheku2019-01-181-1/+1
| | | | * Makefile (MPI_OBJ_BASE): remove mplogic.o.

| | | | | * Makefile (TXR_LDFLAGS): Fix use of wrong assignment operator which clobbers the previous assignment of $(LDFLAGS).
* More reasonable fallback for self path.Kaz Kylheku2018-05-041-2/+4
| | | | | | | | | | | | | | | | * Makefile (opt/txr.o, dbg/txr.o): Set up TXR_REL_PATH preprocessor symbol on command line which specifies the hard installation path derived from the configure prefix. * txr.c (get_self_path): The fallback implementation simply returns TXR_REL_PATH. This will work if in fact the executable is installed at that path. What it means is that the build of TXR which uses this fallback get_self_path will not support relocation: the installation cannot be moved to another directory, yet still find its supporting files. This is better than what we are replacing: not working even in the original installation directory, if not invoked by an absolute path.
