[CWEB] New release 4.3.1.
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 ยง272 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)

As with \.{CWEAVE}, input comes from a source file -\.{foo.w} and from an optional (but now almost mandatory) change file -\.{foo.ch}; output goes to \.{foo.tex}, \.{foo.idx}, and \.{foo.scn}. -Unlike \.{CWEAVE}, there is an additional output file, \.{foo.aux}, -which records all nonexternal definitions. The \.{.aux} file also -serves as an input file on subsequent runs. You should run \.{CTWILL} -twice, once to prime the pump and once to get decent answers. - -Moreover, you must run the output twice through \TeX. (This double duplicity -suggested the original name \.{TWILL}.) After `\.{tex} \.{foo}' you -will have output that looks like final pages except that the entries -of mini-indexes won't be alphabetized. \TeX\ will say `This is the first -pass', and it will produce a weird file called \.{foo.ref}. Say -$$\.{refsort < foo.ref > foo.sref}$$ -and then another `\.{tex} \.{foo}' will produce alphabetized output. -While \TeX\ runs it emits messages filled with numeric data, indicating how -much space is consumed by each program section. If you can decipher these -numbers (see \.{ctwimac.tex}), you can use them to fine-tune the page -layout. You might be tempted to do fine tuning by editing \.{foo.tex} -directly, but it's better to incorporate all changes into \.{foo.ch}. - -The mini-indexes list identifiers that are used but not defined on -each two-page spread. At the end of each section, \.{CTWILL} gives -\TeX\ a list of identifiers used in that section and information -about where they are defined. The macros in \.{ctwimac.tex} figure out -which identifiers should go in each mini-index, based on how the pages -break. (Yes, those macros are pretty hairy.) - -The information that \.{CTWILL} concocts from \.{foo.w} is not always -correct. Sometimes you'll use an identifier that you don't want -indexed; for example, your exposition might talk about |f(x)| when you -don't mean to refer to program variables |f| or |x|. Sometimes you'll -use an identifier that's defined in a header file, unknown to -\.{CTWILL}. Sometimes you'll define a single identifier in several -different places, and \.{CTWILL} won't know which definition to choose. -But all is not lost. \.{CTWILL} guesses right most of the time, and you can -give it the necessary hints in other places via your change file. - -If you think it's easy to write a completely automatic system that doesn't -make \.{CTWILL}'s mistakes and doesn't depend so much on change files, -please do so. - -\.{CTWILL} uses a very simple method to generate mini-index info. By -understanding this method, you will understand how to fix it when things -go wrong. Every identifier has a current ``meaning,'' consisting of its -abstract type and the number of the section in which it was most recently -defined. For example, if your \Cee\ program says `|char *s|' in section~3, -the meaning of~|s| gets changed to `\&{char} $*$, \S3' while \.{CTWILL} -is processing that section. If you refer to~|s| in section~10, and if -|s|~hasn't been redefined in the meantime, and if section~10 doesn't -wind up on the same two-page spread as section~3, the mini-index generated -by section~10 will say ``|s|: \&{char}~$*$, \S3.'' - -The current meaning of every identifier is initially `\.{\\uninitialized}'. -Then \.{CTWILL} reads the \.{.aux} file for your job, if any; this -\.{.aux} file contains all definitions of new meanings in the previous -run, so it tells \.{CTWILL} about definitions that will be occurring -in the future. If all identifiers have a unique definition, they will -have a unique and appropriate meaning in the mini-indexes. - -But some identifiers, like parameters to procedures, may be defined -several times. Others may not be defined at all, because they are -defined elsewhere and mentioned in header files included by the \Cee\ -preprocessor. To solve this problem, \.{CTWILL} provides mechanisms by which -the current meaning of an identifier can be temporarily or permanently -changed. - -For example, the operation -$$\.{@@\$s \{FOO\}3 \\\&\{char\} \$*\$@@>}$$ -changes the current meaning of |s| to the \TeX\ output of `\.{\\\&\{char\}} -\.{\$*\$}' in section~3 of program {\sc FOO}. All entries in the \.{.aux} -file are expressed in the form of this \.{@@\$} operator; therefore you -can use a text editor to paste such entries into a \.{.ch} file, whenever -you want to tell \.{CTWILL} about definitions that are out of order -or from other programs. - -Before reading the \.{.aux} file, \.{CTWILL} actually looks for a file -called \.{system.bux}, which will be read if present. And after -\.{foo.aux}, a third possibility is \.{foo.bux}. The general -convention is to put definitions of system procedures such as |printf| -into \.{system.bux}, and to put definitions found in specifically -foo-ish header files into \.{foo.bux}. Like the \.{.aux} -files, \.{.bux} files should contain only \.{@@\$} specifications; -this rule corresponds to the fact that `bux' is the plural of `\$'. -The \.{.bux} files may also contain \.{@@i} includes. - -A companion operation \.{@@\%} signifies that all \.{@@\$} -specifications from the present point to the beginning of the next -section will define {\it temporary\/} meanings instead of permanent -ones. Temporary meanings are placed into the -mini-index of the current section; the permanent (current) meaning of -the identifier will not be changed, nor will it appear in the -mini-index of the section. If several temporary meanings are assigned -to the same identifier in a section, all will appear in the mini-index. -Each \.{@@\%} toggles the temporary/permanent convention; thus, after -an even number of \.{@@\%} operations in a section, meanings specified -by \.{@@\$} are permanent. - -The operation \.{@@-} followed by an identifier followed by \.{@@>} -specifies that the identifier should not generate a mini-index entry -in the current section (unless, of course, a temporary meaning is assigned). - -If \.{@@-foo@@>} appears in a section where a new permanent meaning is -later defined by the semantics of~\Cee, the current meaning of \\{foo} -will not be redefined; moreover, this current meaning, which may have -been changed by \.{@@\$foo ...@@>}, will also be written to the -\.{.aux} file. Therefore you can control what \.{CTWILL} outputs; you -can keep it from repeatedly contaminating the \.{.aux} file with -things you don't like. - -The meaning specified by \.{@@\$...@@>} generally has four components: -an identifier (followed by space), a program name (enclosed in braces), -a section number (followed by space), and a \TeX\ part. The \TeX\ part -must have fewer than 50 characters. If the \TeX\ part starts -with `\.=', the mini-index entry will contain an equals sign instead -of a colon; for example, -$$\.{@@\$buf\_size \{PROG\}10 =\\T\{200\}@@>}$$ -generates either `$\\{buf\_size}=200$, \S10' or -`$\\{buf\_size}=200$, {\sc PROG}\S10', depending on whether -`{\sc PROG}' is or isn't the title of the current program. If the -\TeX\ part is `\.{\\zip}', the mini-index entry will contain neither -colon nor equals, just a comma. The program name and section number -can also be replaced by a string. For example, -$$\.{@@\$printf "<stdio.h>" \\zip@@>}$$ -will generate a mini-index entry like `\\{printf}, \.{<stdio.h>}.'. - -A special ``proofmode'' is provided so that you can check \.{CTWILL}'s -conclusions about cross-references. Run \.{CTWILL} with the -flag \.{+P}, and \TeX\ will produce a specially formatted document -({\it without\/} mini-indexes) -in which you can check that your specifications are correct. -You should always do this before generating mini-indexes, because -mini-indexes can mask errors if page breaks are favorable but the -errors might reveal themselves later after your program has changed. -The proofmode output is much easier to check than the mini-indexes themselves. - -The control code \.{@@r} or \.{@@R} causes \.{CTWILL} to emit -the \TeX\ macro `\.{\\shortpage}' just before starting the next -section of the program. This causes the section to appear at the top of -a right-hand page, if it would ordinarily have appeared near the bottom -of a left-hand page and split across the pages. (The \.{\\shortpage} macro -is fragile and should be used only in cases where it will not mess up -the output; insert it only when fine-tuning a set of pages.) If the -next section is a starred section, the behavior is slightly different -(but still fragile): The starred section will either be postponed to -a left-hand page, if it normally would begin on a right-hand page, -or vice versa. In other words, \.{@@r@@*} inverts the left/right logic. - -\.{CTANGLE} does not recognize the operations \.{@@\$}, \.{@@\%}, \.{@@-}, -and \.{@@r}, which are unique to \.{CTWILL}.

As with \.{CWEAVE}, input comes from a source file +\.{foo.w} and from an optional (but now almost mandatory) change file +\.{foo.ch}; output goes to \.{foo.tex}, \.{foo.idx}, and \.{foo.scn}. +Unlike \.{CWEAVE}, there is an additional output file, \.{foo.aux}, +which records all nonexternal definitions. The \.{.aux} file also +serves as an input file on subsequent runs. You should run \.{CTWILL} +twice, once to prime the pump and once to get decent answers. + +Moreover, you must run the output twice through \TeX. (This double duplicity +suggested the original name \.{TWILL}.) After `\.{tex} \.{foo}' you +will have output that looks like final pages except that the entries +of mini-indexes won't be alphabetized. \TeX\ will say `This is the first +pass', and it will produce a weird file called \.{foo.ref}. Say +$$\.{refsort < foo.ref > foo.sref}$$ +and then another `\.{tex} \.{foo}' will produce alphabetized output. +While \TeX\ runs it emits messages filled with numeric data, indicating how +much space is consumed by each program section. If you can decipher these +numbers (see \.{ctwimac.tex}), you can use them to fine-tune the page +layout. You might be tempted to do fine tuning by editing \.{foo.tex} +directly, but it's better to incorporate all changes into \.{foo.ch}. + +The mini-indexes list identifiers that are used but not defined on +each two-page spread. At the end of each section, \.{CTWILL} gives +\TeX\ a list of identifiers used in that section and information +about where they are defined. The macros in \.{ctwimac.tex} figure out +which identifiers should go in each mini-index, based on how the pages +break. (Yes, those macros are pretty hairy.) + +The information that \.{CTWILL} concocts from \.{foo.w} is not always +correct. Sometimes you'll use an identifier that you don't want +indexed; for example, your exposition might talk about |f(x)| when you +don't mean to refer to program variables |f| or |x|. Sometimes you'll +use an identifier that's defined in a header file, unknown to +\.{CTWILL}. Sometimes you'll define a single identifier in several +different places, and \.{CTWILL} won't know which definition to choose. +But all is not lost. \.{CTWILL} guesses right most of the time, and you can +give it the necessary hints in other places via your change file. + +If you think it's easy to write a completely automatic system that doesn't +make \.{CTWILL}'s mistakes and doesn't depend so much on change files, +please do so. + +\.{CTWILL} uses a very simple method to generate mini-index info. By +understanding this method, you will understand how to fix it when things +go wrong. Every identifier has a current ``meaning,'' consisting of its +abstract type and the number of the section in which it was most recently +defined. For example, if your \Cee\ program says `|char *s|' in section~3, +the meaning of~|s| gets changed to `\&{char} $*$, \S3' while \.{CTWILL} +is processing that section. If you refer to~|s| in section~10, and if +|s|~hasn't been redefined in the meantime, and if section~10 doesn't +wind up on the same two-page spread as section~3, the mini-index generated +by section~10 will say ``|s|: \&{char}~$*$, \S3.'' + +The current meaning of every identifier is initially `\.{\\uninitialized}'. +Then \.{CTWILL} reads the \.{.aux} file for your job, if any; this +\.{.aux} file contains all definitions of new meanings in the previous +run, so it tells \.{CTWILL} about definitions that will be occurring +in the future. If all identifiers have a unique definition, they will +have a unique and appropriate meaning in the mini-indexes. + +But some identifiers, like parameters to procedures, may be defined +several times. Others may not be defined at all, because they are +defined elsewhere and mentioned in header files included by the \Cee\ +preprocessor. To solve this problem, \.{CTWILL} provides mechanisms by which +the current meaning of an identifier can be temporarily or permanently +changed. + +For example, the operation +$$\.{@@\$s \{FOO\}3 \\\&\{char\} \$*\$@@>}$$ +changes the current meaning of |s| to the \TeX\ output of `\.{\\\&\{char\}} +\.{\$*\$}' in section~3 of program {\sc FOO}. All entries in the \.{.aux} +file are expressed in the form of this \.{@@\$} operator; therefore you +can use a text editor to paste such entries into a \.{.ch} file, whenever +you want to tell \.{CTWILL} about definitions that are out of order +or from other programs. + +Before reading the \.{.aux} file, \.{CTWILL} actually looks for a file +called \.{system.bux}, which will be read if present. And after +\.{foo.aux}, a third possibility is \.{foo.bux}. The general +convention is to put definitions of system procedures such as |printf| +into \.{system.bux}, and to put definitions found in specifically +foo-ish header files into \.{foo.bux}. Like the \.{.aux} +files, \.{.bux} files should contain only \.{@@\$} specifications; +this rule corresponds to the fact that `bux' is the plural of `\$'. +The \.{.bux} files may also contain \.{@@i} includes. + +A companion operation \.{@@\%} signifies that all \.{@@\$} +specifications from the present point to the beginning of the next +section will define {\it temporary\/} meanings instead of permanent +ones. Temporary meanings are placed into the +mini-index of the current section; the permanent (current) meaning of +the identifier will not be changed, nor will it appear in the +mini-index of the section. If several temporary meanings are assigned +to the same identifier in a section, all will appear in the mini-index. +Each \.{@@\%} toggles the temporary/permanent convention; thus, after +an even number of \.{@@\%} operations in a section, meanings specified +by \.{@@\$} are permanent. + +The operation \.{@@-} followed by an identifier followed by \.{@@>} +specifies that the identifier should not generate a mini-index entry +in the current section (unless, of course, a temporary meaning is assigned). + +If \.{@@-foo@@>} appears in a section where a new permanent meaning is +later defined by the semantics of~\Cee, the current meaning of \\{foo} +will not be redefined; moreover, this current meaning, which may have +been changed by \.{@@\$foo ...@@>}, will also be written to the +\.{.aux} file. Therefore you can control what \.{CTWILL} outputs; you +can keep it from repeatedly contaminating the \.{.aux} file with +things you don't like. + +The meaning specified by \.{@@\$...@@>} generally has four components: +an identifier (followed by space), a program name (enclosed in braces), +a section number (followed by space), and a \TeX\ part. The \TeX\ part +must have fewer than 50 characters. If the \TeX\ part starts +with `\.=', the mini-index entry will contain an equals sign instead +of a colon; for example, +$$\.{@@\$buf\_size \{PROG\}10 =\\T\{200\}@@>}$$ +generates either `$\\{buf\_size}=200$, \S10' or +`$\\{buf\_size}=200$, {\sc PROG}\S10', depending on whether +`{\sc PROG}' is or isn't the title of the current program. If the +\TeX\ part is `\.{\\zip}', the mini-index entry will contain neither +colon nor equals, just a comma. The program name and section number +can also be replaced by a string. For example, +$$\.{@@\$printf "<stdio.h>" \\zip@@>}$$ +will generate a mini-index entry like `\\{printf}, \.{<stdio.h>}.'. + +A special ``proofmode'' is provided so that you can check \.{CTWILL}'s +conclusions about cross-references. Run \.{CTWILL} with the +flag \.{+P}, and \TeX\ will produce a specially formatted document +({\it without\/} mini-indexes) +in which you can check that your specifications are correct. +You should always do this before generating mini-indexes, because +mini-indexes can mask errors if page breaks are favorable but the +errors might reveal themselves later after your program has changed. +The proofmode output is much easier to check than the mini-indexes themselves. + +The control code \.{@@r} or \.{@@R} causes \.{CTWILL} to emit +the \TeX\ macro `\.{\\shortpage}' just before starting the next +section of the program. This causes the section to appear at the top of +a right-hand page, if it would ordinarily have appeared near the bottom +of a left-hand page and split across the pages. (The \.{\\shortpage} macro +is fragile and should be used only in cases where it will not mess up +the output; insert it only when fine-tuning a set of pages.) If the +next section is a starred section, the behavior is slightly different +(but still fragile): The starred section will either be postponed to +a left-hand page, if it normally would begin on a right-hand page, +or vice versa. In other words, \.{@@r@@*} inverts the left/right logic. + +\.{CTANGLE} does not recognize the operations \.{@@\$}, \.{@@\%}, \.{@@-}, +and \.{@@r}, which are unique to \.{CTWILL}. But that is no problem, +since you use them only in change files set up for book publishing, +which are quite different from the change files you set up for tangling. + +(End of user manual.) + +@d max_tex_chars 50 /* limit on the \TeX\ part of a meaning */ + +@q Section 25->274. @> +@* Temporary and permanent meanings. +\.{CTWILL} has special data structures to keep track of current +and temporary meanings.
