2022-06-05[CWEB] Release 4.8.Andreas Scherer
This new release provides the following features: * @<Code sections@> can be used freely in any #if -- #elif -- #else -- #endif preprocessor branches without bashing the debugger * The GCC compiler can be invoked with option -Wimplicit-fallthrough=2 on all CWEB code modules and will acknowledge /* fall through */ comments in the tangled C code * Simple C casts like '(double)x' are formatted with non-breaking small spaces as '(double)\,x' in the woven TeX output * The HINT boolean macros are now in lowercase (as in ifhint.tex) * Comma-separated lists of variable declarations are formatted in accordance with function parameter lists and enumerations, i.e., comma is handled in math-mode with associated small spacing and it fixes these bugs: * Section @<Preprocessor definitions@> isn't overprinted (in PDF) * Trivial CWEB code is formatted correctly (issue #36) * Nested type definitions are recognized (issue #34) Major remaining bug (as of CWEB 4.3.1): * Issue #38 as described earlier git-svn-id: svn://tug.org/texlive/trunk@63490 c570f23f-e606-0410-a88d-b1316a301751
2022-03-10[CWEB] Make 'fall thru' comments active.Andreas Scherer
This is specific for GCC, but totally harmless for any other C compiler: GCC accepts 'fall thru' comments from the CWEB sources with its option '-Wimplicit-fallthrough=2', when we push these comments over to the tangled C code. git-svn-id: svn://tug.org/texlive/trunk@62584 c570f23f-e606-0410-a88d-b1316a301751
2022-02-19[CWEB] Permit indentation of preprocessing directives.Andreas Scherer
The C processor allows whitespace before and after the '#' of preprocessing directives, e.g., some MetaPost code uses this feature. In order to permit more liberal code layout, we only expect the '#' to be the first character in the buffer, followed by some optional whitespace. CWEB takes care that 'id_first' is the first non-whitespace character in the 'buffer' (and 'id_loc' is the first character _after_ the directive name). git-svn-id: svn://tug.org/texlive/trunk@62084 c570f23f-e606-0410-a88d-b1316a301751

2022-02-18[CWEB] Avoid preprocessor calamities.Andreas Scherer
Trying to fix all loopholes in weird stuff like https://github.com/ascherer/cweb/blob/cweb-4.8-dev/if.w by repeating '#line' directives after all '#elif', '#else', and '#endif' preprocessor statements. In almost all cases this information is redundant, but in the past years people have come up with the idea to jump to '@<code sections@>' in '#if' blocks. git-svn-id: svn://tug.org/texlive/trunk@62066 c570f23f-e606-0410-a88d-b1316a301751

git-svn-id: svn://tug.org/texlive/trunk@62035 c570f23f-e606-0410-a88d-b1316a301751
2022-02-14[CWEB] Add '#line' after '#endif'.Andreas Scherer
Some people incorporate '@<Section code@>' in preprocessor #if-blocks. (AFAIKS, DEK did this exactly _once_ in his 'reflect.w' example code, but never in any larger system program.) This adds material (lines of code) in the ctangle'd C code wrapped in '#line' directives for the benefit of the compiler/debugger/w.h.y. Depending on the #if-condition, the #line directives in the #if-block get eliminated and the resulting status from previous #line directives kicks the compiler (__LINE__ and possibly __FILE__) and the debugger (e.g., gdb, MSVS) off the track. git-svn-id: svn://tug.org/texlive/trunk@62021 c570f23f-e606-0410-a88d-b1316a301751

git-svn-id: svn://tug.org/texlive/trunk@61893 c570f23f-e606-0410-a88d-b1316a301751
2021-12-26[CWEB] New release 4.6.Andreas Scherer
Major changes since CWEB 4.5: * Restore '\T' macro backward compatibility. CWEB 4.3 introduced a major change in the '\T' macro to allow C++ 'hex exponent' notation (e.g., 0x1FFFFp10). This made CWEAVE/CTWILL mutually incompatible with non-matching versions of their set of macros and v.v. This release tries to reestablish the standard behavior at least for numeric constants. Of course, 'old' CWEAVE/CTWILL won't deliver on 'hex exponents' in the CWEB input, but those should be rare anyway. * Restore 'classic' PDF page dimensions. Heiko's PDF files of 2014 used 'Executive' page dimensions, i.e., 7.5in times 10in. C/WEB's internal inch values suggest to use those plus a 0.5in border on each side. * Revert meaning of option 'c'. Option 'c' is OFF by default to avoid spurious entries in build.log. * 'squash'/'reduce' have been straightened out for k=1,..,4. * Code beautifications for 'make fullmanual'. * Code cleanup for internal reasons. * Cleanup in 'prod.w' (indentation et al.). * New 'prod-cweave.w' (along 'prod-twill.w') for material from CWEBbin. * Fixes for option '-o' (didn't work as advertised in border cases). * New signature for the 'make_ministring' function in CTWILL. git-svn-id: svn://tug.org/texlive/trunk@61411 c570f23f-e606-0410-a88d-b1316a301751
2021-10-11[CWEB] Pre-release candidate 2 for CWEB 4.6.Andreas Scherer
When the CWEB programs are called with option '-c' (the default), no intermediate output files are created at all. After thoroughly testing these programs, I'll prepare the final release of CWEB 4.6 in the coming weeks (months). git-svn-id: svn://tug.org/texlive/trunk@60728 c570f23f-e606-0410-a88d-b1316a301751
2021-09-16[CWEB] Pre-release of version 4.6.Andreas Scherer
This is a service update due to general demand: * Option 'c' is OFF by default to avoid spurious entries in build.log. * 'squash'/'reduce' have been straightened out for k=1,..,4. * Code beautifications for 'make fullmanual'. * Code cleanup for internal reasons. * Cleanup in 'prod.w' (indentation et al.). * New 'prod-cweave.w' (along 'prod-twill.w') for material from CWEBbin. * Fixes for option '-o' (didn't work as advertised in border cases). * New signature for the 'make_ministring' function in CTWILL. git-svn-id: svn://tug.org/texlive/trunk@60519 c570f23f-e606-0410-a88d-b1316a301751
2021-07-14[CWEB] New release 4.5.Andreas Scherer
This is a service release for CWEB 4.0. * Upstream CWEB 4.5 was reviewed with the 'splint' utility. This resulted in lots of cast changes and a few code improvements. * All 'length' variables are retyped to 'size_t'. * <stdbool.h> is replaced by <kpathsea/simpletypes.h> to keep CWEB compatible with antique systems that still support TeX Live. git-svn-id: svn://tug.org/texlive/trunk@59926 c570f23f-e606-0410-a88d-b1316a301751
2021-06-06[CWEB] New release 4.4.Andreas Scherer
This is yet another service release for CWEB 4.0. * Upstream CWEB 4.4 has been reset to the original buffer sizes of CWEB 3.64c. These are now also used in stand-alone CWEBbin. CWEB for TeX Live uses extended/maxed-out buffer settings. * A few minor typographical bugs were fixed. * Tons of minutiae were addressed in the 'fullmanual' documents. git-svn-id: svn://tug.org/texlive/trunk@59486 c570f23f-e606-0410-a88d-b1316a301751
2021-05-03[CWEB] New release 4.3.1.Andreas Scherer
This release is almost the same as CWEB 4.3 of 2021-04-16, but * it fixes the indexing bug in CWEAVE/CTWILL that got retracted * it extracts and collects all additions made in CTWILL, so that the section numbers of CWEAVE are retained up to §272 and new material is described in the (first) appendix, including the CTWILL user manual * it provides fully revised and (hopefully) corrected mini-indexes for CTWILL, if it is processed by itself (to be published in package 'knuth-pdf' on CTAN) git-svn-id: svn://tug.org/texlive/trunk@59061 c570f23f-e606-0410-a88d-b1316a301751
2021-05-02Revert "[CWEB] New release 4.3."Andreas Scherer
This reverts commit 3ccac2a7d0f4a19dde861c6f4c178e853d90f0cc. CWEB 4.3 is seriously broken. git-svn-id: svn://tug.org/texlive/trunk@59048 c570f23f-e606-0410-a88d-b1316a301751
2021-04-16[CWEB] New release 4.3.Andreas Scherer
This release introduces new features to CWEB 4: * Former option '-t' is now called '-c'. - New option '-t' for CWEAVE when dealing with 'typename' in C++ templates. - New option '-k' for CTANGLE to keep '-separators in numeric literals. * Support for "variadic macros" along "variadic functions". * @d is printed similar to #define (and vice versa): - '#' is no longer printed in boldface. - Spacing is similar in most cases. * Support for extended C99/C++ numeric literals: - hexadecimal, octal, and -- new! -- binary numbers. - NOTE: 'cwebmac.tex 4.3' is NOT compatible with CWEAVE 4.2 and older and vice versa. * Long parameter lists in ANSI function definitions are indented similar to old-style function parameters. - Option '-i' works similar for old-style and modern function headers. * Additional C99/C++ keywords -- from 'alignas' to 'thread_local' -- are supported internally. * '@i'nclude file 'iso_types.w' for numeric types (in addition to 'c++lib.w'). * Countless code modifications, including some corrections amd improvements. Thanks and cudos to Github user "@texdraft" for numerous contributions to this feature release! git-svn-id: svn://tug.org/texlive/trunk@58884 c570f23f-e606-0410-a88d-b1316a301751

2021-02-07CWEB – release 4.0, 2021-02-07.Andreas Scherer
In the course of the "2021 TeX tuneup", Don Knuth kindly transferred the responsibility for CWEB to me; see the original CWEB home page (https://www-cs-faculty.stanford.edu/~knuth/cweb.html), section "CWEB 4.0" and the updated CWEB development project (https://github.com/ascherer/cweb). This first new release draws heavily on the multi-decade work collected in my "CWEBbin" project (https://github.com/ascherer/cwebbin). I moved (almost) all stuff from the "*-patch.*" changefiles into the new CWEB sources and applied all of the "*-ansi.*" changes as well. Moreover, I made "common.h" the full interface of "common.w" in order to avoid code redundancy. And I tried to fix as many of the bugs reported by email to DEK and/or tex-k@tug.org. In total, "make; make cautiously; make fullmanual" runs flawlessly with GCC on Linux and with LLVM on MacOS. After the release of "CWEB 4.0", also "CWEBbin 2021" has also been fully revised. Thousands of lines of changefiles could be purged. What's left are the clearcut extensions for CWEB and the additional stuff for integration in "TeX Live 2021". git-svn-id: svn://tug.org/texlive/trunk@57658 c570f23f-e606-0410-a88d-b1316a301751
