This macro - does the real work. - - The \`\_printinverbatim``{<text>}` macro is used for `\code{<text>}` printing and for - \code{`}<text>\code{`} printing. It is defined as `\hbox`, so the in-verbatim <text> - will be never broken. But you can re-define this macro. - - When `\code` occurs in PDF outlines then it does the same as `\detokenize`. - The macro for preparing outlines sets `\escapechar` to $-1$ and uses - \^`\_regoul` token list before `\edef`. - - The `\code` is not `\proteced` because we want it expands to - `\unexpanded{\code<space>{<text>}}` in `\write` parameters.

It should be used only - in a group, so we prepare a new catcode table with \"verbatim" catcodes and we define - it as\nl `\_catcodetable`\`\_verbatimcatcodes`.

Then new such values are stored. The declared charater is activated - by `\_adef` as a macro (active character) which opens a group, - does `\_setverb` and other settings and reads its parameter until second the same - character. This is done by the \`\_readverb` macro. Finally it prints scanned - `<text>` by \^`\_printinverbatim` and closes group. Suppose that `\activettchar"` is - used. Then the following work is schematically done: - \begtt - \_def "{\_begingroup \_setverb ... \_readverb} - \_def \_readverb #1"{\_printinverbatim{#1}\_endgroup} - \endtt - Note that the second occurrence of `"` is not active because `\_setverb` - deactivates it. - \_cod ---------------------------- - -\_def\_activettchar#1{% - \_ifx\_savedttchar\_undefined\_else \_catcode\_savedttchar=\_savedttcharc \_fi - \_chardef\_savedttchar=`#1 - \_chardef\_savedttcharc=\_catcode`#1 - \_adef{#1}{\_begingroup \_setverb \_adef{ }{\ }\_ttfont \_the\_everyintt\_relax \_readverb}% - \_def\_readverb ##1#1{\_printinverbatim{##1}\_endgroup}% -} -\_public \activettchar ; - - \_doc ---------------------------- - \`\begtt` is defined only as public. We don't need private `\_begtt` variant. - This macro is defined by `\eoldef`, so user can put a parameter at the - same line where `\begtt` is. This `#1` parameter is used after `\_everytt` - parameters settings, so user can change them locally. - - The `\begtt` macro opens group, does \^`\_setverb` and another preprocessing, sets - `\endlinechar` to `^^J` and reads the following text in verbatim mode - until \`\endtt` occurs. This scanning is done by \`\_startverb` macro which is - defined as: - \begtt \adef/{\bslash} - \_def\_startverb #1/endtt #2^^J{...} - \endtt - We must to ensure that the backslash in `\endtt` has category 12 (this is a - reason of the `\ea` chain in real code). - The `#2` is something between `\endtt` and end of the same line and it is simply - ignored. - - The `\_startverb` puts the scanned data to \`\_prepareverbdata`. It sets the data - to `\_tmpb` without changes by default, but you should re-define it in order - to do special changes, if you want. (For example, \^`\hisyntax` redefines - this macro.) The scanned data have `^^J` at each end of line and all spaces are - active characters (defined as {\visiblesp`\ `}). - Other characters have normal category 11 or 12. - - When `\_prepareverbdata` finishes then `\_startverb` runs \`\_printverb` loop - over each line of the data and does a final work: last skip plus `\noindent` - in the next paragraph. - - The `\_printverb` macro calls \`\_printverbline``{<line>}` to each scanned line of - verbatim text. This macro expect that it strarts in vertical mode and it must - do `\par` in order to return the vertical mode. The \`\_printverblinenum` - is used here: it does nothing when `\_ttline`\code{<0} else it prints the line - number using `\_llap`. - \_cod ---------------------------- - -\_eoldef \begtt#1{\_par \_wipeepar - \_vskip\_parskip \_ttskip - \_begingroup - \_setverb - \_ifnum\_ttline<0 \_let\_printverblinenum=\_relax \_else \_initverblinenum \_fi - \_adef{ }{\ }\_adef\^^I{\t}\_parindent=\_ttindent \_parskip=0pt - \_def\t{\_hskip \_dimexpr\_tabspaces em/2\_relax}% - \_the\_everytt \_relax #1\_relax \_ttfont - \_endlinechar=`^^J - \_startverb -} -\_ea\_def\_ea\_startverb \_ea#\ea1\_csstring\\endtt#2^^J{% - \_prepareverbdata\_tmpb{#1^^J}% - \_ea\_printverb \_tmpb\_end - \_par - \_endgroup \_ttskip - \_isnextchar\_par{}{\_noindent}% -} -\_def\_printverb #1^^J#2{\_ifx\_end#2 - \_bgroup \_adef{ }{}\_def\t{}% - \_ifcat&\_egroup \_else\_egroup \_printverbline{#1}\_fi - \_else - \_printverbline{#1}% - \_ea \_printverb \_ea #2% - \_fi -} -\_def\_prepareverbdata#1#2{\_def#1{#2}} -\_def\_printverbline#1{\_penalty \_ttpenalty - \_indent \_printverblinenum \_kern\_ttshift #1\par} -\_def\_initverblinenum{\_tenrm \_thefontscale[700]\_ea\_let\_ea\_sevenrm\_the\_font} -\_def\_printverblinenum{\_global\_advance\_ttline by1 \_llap{\_sevenrm \_the\_ttline\_kern.9em}} - - \_doc ---------------------------- - Macro \`\verbinput` uses a file read previously or opens the given file. Then - it runs the parameter scanning by \`\_viscanparameter` and \`\_viscanminus`. - Finally the \`\_doverbinput` is run. At begining of `\_doverbinput`, we have - `\_viline`= number of lines already read using previous `\verbinput`, - `\_vinolines`= the number of lines we need to skip and `\_vidolnes`= the - number of lines we need to print. - Similar preparation is done as in `\begtt` after the group is opened. Then - we skip \`\_vinolines` lines in a loop a and we read \`\_vidolines` lines. The - read data is accumulated into `\_tmpb` macro. The next steps are equal to - the steps done in \^`\_startverb` macro: data are processed via - \^`\_prepareverbdata` and printed via \^`\_printverb` loop. - \_cod \_fin ---------------------- - -\_def\_verbinput #1(#2) #3 {\_par \_def\_tmpa{#3}% - \_def\_tmpb{#1}% cmds used in local group - \_ifx\_vifilename\_tmpa \_else - \_openin\_vifile={#3}% - \_global\_viline=0 \_global\_let\_vifilename=\_tmpa - \_ifeof\_vifile - \_opwarning{\_noexpand\verbinput - file "#3" is unable to reading} - \_ea\_ea\_ea\_skiptorelax - \_fi - \_fi - \_viscanparameter #2+\_relax -} -\_def\_skiptorelax#1\_relax{} - -\_def \_viscanparameter #1+#2\_relax{% - \_if$#2$\_viscanminus(#1)\_else \_viscanplus(#1+#2)\_fi -} -\_def\_viscanplus(#1+#2+){% - \_if$#1$\_tmpnum=\_viline - \_else \_ifnum#1<0 \_tmpnum=\_viline \_advance\_tmpnum by-#1 - \_else \_tmpnum=#1 - \_advance\_tmpnum by-1 - \_ifnum\_tmpnum<0 \_tmpnum=0 \_fi % (0+13) = (1+13) - \_fi \_fi - \_edef\_vinolines{\_the\_tmpnum}% - \_if$#2$\_def\_vidolines{0}\_else\_edef\_vidolines{#2}\_fi - \_doverbinput -} -\_def\_viscanminus(#1-#2){% - \_if$#1$\_tmpnum=0 - \_else \_tmpnum=#1 \_advance\_tmpnum by-1 \_fi - \_ifnum\_tmpnum<0 \_tmpnum=0 \_fi % (0-13) = (1-13) - \_edef\_vinolines{\_the\_tmpnum}% - \_if$#2$\_tmpnum=0 - \_else \_tmpnum=#2 \_advance\_tmpnum by-\_vinolines \_fi - \_edef\_vidolines{\_the\_tmpnum}% - \_doverbinput -} -\_def\_doverbinput{% - \_tmpnum=\_vinolines - \_advance\_tmpnum by-\_viline - \_ifnum\_tmpnum<0 - \_openin\_vifile=\_vifilename\_space - \_global\_viline=0 - \_else - \_edef\_vinolines{\_the\_tmpnum}% - \_fi - \_vskip\_parskip \_ttskip \_wipeepar - \_begingroup - \_ifnum\_ttline<-1 \_let\_printverblinenum=\_relax \_else \_initverblinenum \_fi - \_setverb \_adef{ }{\ }\_adef\^^I{\t}\_parindent=\_ttindent \_parskip=0pt - \_def\t{\_hskip \_dimexpr\_tabspaces em/2\_relax}% - \_the\_everytt\_relax \_tmpb\_relax \_ttfont - \_endlinechar=`^^J \_tmpnum=0 - \_loop \_ifeof\_vifile \_tmpnum=\_vinolines\_space \_fi - \_ifnum\_tmpnum<\_vinolines\_space - \_vireadline \_advance\_tmpnum by1 \_repeat %% skip lines - \_edef\_ttlinesave{\_ttline=\_the\_ttline}% - \_ifnum\_ttline=-1 \_ttline=\_viline \_fi - \_tmpnum=0 \_def\_tmpb{}% - \_ifnum\_vidolines=0 \_tmpnum=-1 \_fi - \_ifeof\_vifile \_tmpnum=\_vidolines\_space \_fi - \_loop \_ifnum\_tmpnum<\_vidolines\_space - \_vireadline - \_ifnum\_vidolines=0 \_else\_advance\_tmpnum by1 \_fi - \_ifeof\_vifile \_tmpnum=\_vidolines\_space \_else \_visaveline \_fi %% save line - \_repeat - \_ea\_prepareverbdata \_ea \_tmpb\_ea{\_tmpb^^J}% - \_ea\_printverb \_tmpb\_end - \_global\_ttlinesave - \_par - \_endgroup - \_ttskip - \_isnextchar\_par{}{\_noindent}% -} -\_def\_vireadline{\_read\_vifile to \_tmp \_global\_advance\_viline by1 } -\_def\_visaveline{\_ea\_addto\_ea\_tmpb\_ea{\_tmp}} - -\_public \verbinput ; - - \_doc ----------------------------- - The \`\visiblesp` sets spaces as visible characters \char9251. - It redefines {\visiblesp`\ `} primitive, so it is useful for verbatim modes only. - \_cod ----------------------------- - -\_def \_visiblesp{\_ifx\_initunifonts\_relax \_def\ {\_char9251 }% - \_else \_def\ {\_char32 }\_fi} - -\_public \visiblesp ; - -\_endcode - -\_endinput - -History: -2020-04-22 ... \ttshift introduced -2020-04-06 ... \visiblesp added -2020-04-04 ... ^^I activated as \t for multiline verbatim - \verbinput <cmds> (...) <filename>, <cmds> added. |
