60 YaTeX automates typesetting and previewing of LaTeX and enables
61 completing input of LaTeX mark-up command such as
62 @code{\begin@{@}}..@code{\end@{@}}.
64 YaTeX also supports Demacs which runs on MS-DOS(386), Mule (Multi
65 Language Enhancement to GNU Emacs), and latex on DOS.

183 Typing @kbd{[prefix] t j}, the current editing window will be divided
184 horizontally when you invoke latex command, and log message of La@TeX{}
185 typesetting will be displayed in the other window; called typesetting
186 buffer. The typesetting buffer automatically scrolls up and traces
187 La@TeX{} warnings and error messages. If you see latex stopping by an
188 error, you can send string to latex in the typesetting buffer.
190 If an error stops the La@TeX{} typesetting, this key stroke will
191 move the cursor to the line where La@TeX{} error is detected.
193 @table @kbd

198 @end table
200 If you find a noticeable error, move to the typesetting buffer and move
201 the cursor on the line of error message and type @kbd{SPACE} key. This
202 makes the cursor move to corresponding source line.
204 YaTeX-typeset-region invoked by @kbd{[prefix] tr} call typesetter
205 for region. The region is specified by standard point and mark, or
206 by @code{%#BEGIN} and @code{%#END} marks. Selected region will be
207 copied to the temporary file @file{texput.tex} with the same preamble
208 as the main file of current editing sources. Be sure to put
209 all local macro settings in preamble, not after @code{\begin@{document@}}.
210 The method of specification of the region is shown in the
211 section @xref{%#notation}.
213 The documentclass for typeset-region is the same as that of editing
214 file if you edit one file, and is the same as main file's if you
215 edit splitting files.
217 The @kbd{[prefix] te} key automatically marks current inner environment
218 or inner math mode and then call typeset-region with marked region. This
219 is convenient to quick view of current tabular environment or current
220 editing formulas. Keeping previewer window for @file{texput.dvi} is handy
221 for debugging. Since @kbd{[prefix] te} selects the inner-most environment
222 as region, it is not suitable for partial typesetting of doubly or more
223 composed environment. If you want to do partial typesetting for a nested
224 environment, use @kbd{[prefix] tr} for static-region, which is described
225 in the section @xref{%#notation}.

287 @example
288 %#!latex main.tex
289 @end example
291 @noindent
292 will be helpful to execute latex on main file from sub text buffer. Since
293 this command line after @kbd{%#!} will be sent to shell literally, next
294 description makes it convenient to use ghostview as dvi-previewer.
296 @example
297 %#!latex main && dvi2ps main.dvi > main
298 @end example
300 @noindent
301 Note that YaTeX assumes the component before the last period of
302 the last word in this line as base name of the main La@TeX{} source.
303 The @code{%f} notation in this line is replaced by main file name, and
304 @code{%r} replaced by root name of main file name. If you specify
305 @code{%f} or @code{%r}, YaTeX always ask you the name of main file at the
306 first typesetting.
308 To make best use of the feature of inter-file jumping by
309 @kbd{[prefix] g} (see @ref{Cursor jump}), take described below into
310 consideration.
312 @itemize
313 @item You can put split texts in sub directory, but not in
314 sub directory of sub directory.
315 @item In the main text, specify the child file name with relative path name
316 such as \include@{chap1/sub@}, when you include the file in
317 a sub-directory.
318 @item In a sub-text, write @code{%#!latex main.tex} even if @file{main.tex}
319 is in the parent directory(not %#!latex ../main.tex).

326 @cindex Fixed region
328 Typeset-region by @kbd{[prefix] tr} passes the region between point and
329 mark to typesetting command by default. But when you want to typeset
330 static region, enclose the region by @code{%#BEGIN} and @code{%#END} as
331 follows.
333 @example
334 %#BEGIN
335 TheRegionYouWantToTypesetManyTimes
336 %#END
337 @end example
339 This is the rule of deciding the region.
341 @enumerate

361 @itemize
362 @item Between point and mark(standard method of Emacs).
363 @end itemize
364 @end enumerate
366 It is useful to write @code{%#BEGIN} in the previous line of \begin and
367 @code{%#END} in the next line of \@code{end} when you try complex
368 environment such as `tabular' many times. It is also useful to put only
369 @code{%#BEGIN} alone at the middle of very long text. Do not forget to
370 erase @code{%#BEGIN} @code{%#END} pair.

377 Lpr format is specified by three Lisp variables. Here are the
378 default values of them.
380 @table @code
381 @item (1)dviprint-command-format
382 @code{"dvi2ps %f %t %s | lpr"}

385 @item (3)dviprint-to-format
386 @code{"-t %e"}
387 @end table
389 On YaTeX-lpr, @code{%s} in (1) is replaced by the file name of main
390 text, @code{%f} by contents of (2), %t by contents of (3). At these
391 replacements, @code{%b} in (2) is also replaced by the number of beginning
392 page, @code{%e} in (3) is replaced by the number of ending page. But
393 @code{%f} and @code{%t} are ignored when you omit the range of print-out
394 by @kbd{C-u [prefix] tl}.
396 If you want to change this lpr format temporarily, put a command
397 such as follows somewhere in the text:
399 @example
400 %#LPR dvi2ps %f %t %s | 4up -page 4 | texfix | lpr -Plp2
401 @end example
403 And if you want YaTeX not to ask you the range of printing
404 out, the next example may be helpful.

639 YaTeX puts

642 \vspace*@{@}
643 @end example
645 @noindent
646 and move the cursor in the braces.
648 In La@TeX{} command, there are commands which take more than one
649 arguments such as @code{\addtolength@{\topmargin@}@{8mm@}}. To complete these
650 commands, invoke section-type completion with universal argument as,
651 @cindex number of argument
653 @example
654 C-u 2 [prefix] s (or ESC 2 [prefix] s)
655 @end example
657 @noindent
658 and make answers in minibuffer like this.
660 @example
661 (C-v for view) \???@{@} (default vspace*): addtolength
662 \addtolength@{???@}: \topmargin
663 Argument 2: 8mm
664 @end example
666 @code{\addtolength} and the first argument @code{\topmargin} can be typed
667 easily by completing read. Since YaTeX also learns the number of
668 arguments of section-type command and will ask that many arguments in
669 future completion, you had better tell the number of arguments to YaTeX at
670 the first completion of the new word. But you can change the number of
671 arguments by calling the completion with different universal argument
672 again.
675 Invoking section-type completion with @code{[Prefix] S} (Capital `S')
676 includes the region as the first argument of section-type command.
678 The section/large/maketitle type completion can work at the
679 prompt for the argument of other section-type completion.
680 Nested La@TeX{} commands are efficiently read with the recursive
681 completion by typing YaTeX's completion key sequence in the
682 minibuffer.

864 Arrow marks, sigma mark and those signs mainly used in the
865 TeX's math environment are completed by key sequences which
866 imitate the corresponding symbols graphically. This completion
867 only works in the math environment. YaTeX automatically detects
868 whether the cursor located in math environment or not, and
869 change the behavior of key strokes @kbd{;} and @kbd{:}.
871 By the way, we often express the leftarrow mark by `<-' for example.
872 Considering such image, you can write @code{\leftarrow} by typing @kbd{<-}
873 after @kbd{;} (semicolon) as a prefix. In the same way,
874 @code{\longleftarrow} (@code{<--}) is completed by typing @kbd{;<--},
875 infinity mark which is imitated by @code{oo} is completed by typing
876 @kbd{;oo}.
878 Here are the sample operations in YaTeX math-mode.
880 @example
881 INPUT Completed La@TeX{} commands
882 ; < - @code{\leftarrow}
883 ; < - - @code{\longleftarrow}
884 ; < - - > @code{\longleftrightarrow}

889 In any case, you can quit from image completion and can move
890 to the next editing operation if the La@TeX{} command you want is
891 shown in the buffer.
893 @code{;} itself in math-environment is inserted by @kbd{;;}. Typing
894 @kbd{TAB} in the midst of image completion shows all of the La@TeX{}
895 commands that start with the same name as string you previously typed in.
896 In this menu buffer, press @kbd{RET} after moving the cursor (by @kbd{n},
897 @kbd{p}, @kbd{b}, @kbd{f}) to insert the La@TeX{} command.
899 To know all of the completion table, type @kbd{TAB} just after @kbd{;}.

1268 on that item.
1270 YaTeX uses the value of the variable @code{YaTeX-item-regexp} as the
1271 regular expression to search item header in itemize environment.
1272 If you make a newcommand to itemize terms(e.g. @code{\underlineitem}), put
1274 @lisp
1275 (setq YaTeX-item-regexp
1276 "\\(\\\\\\(sub\\)*item\\)\\|\\(\\\\underlineitem\\)")
1277 @end lisp
1278 @cindex YaTeX-item-regexp
1280 in your @file{~/.emacs}. If you are not familiar with regular expression
1281 for Emacs-Lisp, name a newcommand for `itemize' beginning with
1282 @code{\item} such as @code{\itembf}, not @code{\bfitem}.
1284 This function reformats the @code{\item} into `hang-indented' style.
1285 For example:
1287 @example
1288 itemize, enumerate environment:
1289 >
1290 >\item[foo] `foo' is the typical word for describing an
1291 > arbitrarily written....
1292 description environment:
1293 > \item[bar] When the word `for' is used as an arbitrarily
1294 > word, `bar' is bound to follow it.
1295 @end example
1297 Note that the indent depth of an @code{\item} word and its descriptive
1298 paragraph are the same in latter case. If you want to use different
1299 depth, invoke fill-paragraph at the beginning of non-whitespace
1300 character(see below).
1302 @section Filling paragraph
1303 @cindex Filling paragraph
1304 @cindex M-q
1306 Fill-paragraph is little bit adapted for La@TeX{} sources. It retains from
1307 filling in certain environments where formatting leads to a disaster such
1308 as verbatim, tabular, or so. And it protects @code{\verb} expressions
1309 from being folded (The variable @code{YaTeX-verb-regexp} controls this).
1310 Besides, putting cursor on the first occurrence of non-whitespace
1311 character on a line changes the fill-prefix temporarily to the depth of
1312 the line.

1321 @example
1322 \includeonly@{CurrentEditingFileName@}

1326 in the main file reduces the time of typesetting. If you want

1331 @end example
1333 @noindent

1341 in the minibuffer. Type @kbd{a} if you want to add the current file name

1358 Name&Position&Post No.&Addr.&Phone No.&FAX No.&

1363 &&&(???)
1364 \\ \hline
1365 \end@{tabular@}
1366 @end example
1368 Suppose you have the cursor located at @code{(???)} mark, can you tell
1369 which column it is belonging at once? Maybe no. In such case,
1370 type
1372 @table @kbd
1373 @item [prefix] &
1374 @dots{} What column
1375 @end table
1377 @noindent
1378 in that position. YaTeX tells you the column header of the
1379 current field. Since YaTeX assumes the first line of tabular
1380 environment as a row of column headers, you can create a row of
1381 virtual column headers by putting them in the first line and
1382 commenting that line with @code{%}.

1425 If you want to apply these trick to other environments, @code{foo}

1427 @code{YaTeX-intelligent-newline-foo} to insert corresponding contents.
1428 That function will be called at the beginning of the next line after the

1430 @code{YaTeX-indent-line} is designed to indent the current line properly,
1431 calling this function before your code to insert certain contents must be

1474 There are two help file, `global help' and `private help'. The former
1475 file contains the descriptions on the standard La@TeX{} command and is
1476 specified its name by variable @code{YaTeX-help-file}. Usually, the
1477 global help file should be located in public space (@code{$EMACSEXECPATH}
1478 by default) and should be world writable so that anyone can update it to
1479 enrich its contents. The latter file contains descriptions on
1480 non-standard or personal command definitions and is specified by
1481 @code{YaTeX-help-file-private}. This file should be put into private
1482 directory.
1484 @section Online apropos
1486 `Online apropos' is an equivalent of GNU Emacs's apropos. It
1487 shows all the documentations that contains the keyword entered by
1488 the user.
1490 @section When no descriptions are found...
1492 If there is no description on a command in help files, YaTeX
1493 requires you to write a description on that command. If you are
1494 willing to do, determine which help file to add and write the
1495 description on it referring your manual of (La)TeX. Please send
1496 me your additional descriptions if you describe the help on some
1497 standard commands. I might want to include it in the next

2052 @subsection How the add-in function works
2054 There are three types of add-in.
2056 @enumerate
2057 @item
2058 Option add-in
2059 @item
2060 argument add-in
2061 @item
2062 enclosing add-in
2063 @end enumerate
2065 @dfn{Option add-in} returns the
2066 La@TeX{}'s optional parameters such as optional strings after
2067 @code{\begin@{ENV@}}, optional strings between a section-type command
2068 and its first argument, and optional strings just after type
2069 maketitle-type command. The following illustrates the name of add-in
2070 functions, where underlined strings are generated by add-in functions.
2072 @display
2073 \begin@{table@}[ht] (Function name: YaTeX:table)
2074 ~~~~
2075 \put(100,200)@{@} (Function name: YaTeX:put)
2076 ~~~~~~~~~
2077 \sum_@{i=0@}^@{n@} (Function name: YaTeX:sum)
2078 ~~~~~~~~~~
2079 @end display
2081 Obviously, the function name is decided by concatenating the prefix
2082 `YaTeX:' and La@TeX{} command's name.
2084 Another add-in type is @dfn{argument add-in}, which completes arguments
2085 for section-type commands.
2087 @display
2088 \newcommand@{\foo@}@{bar@} (Function name: YaTeX::newcommand)
2089 ~~~~ ~~~
2090 @end display
2092 When the section-type command is inputted, the function named by
2093 concatenating `YaTeX::' and section-type command, is called automatically
2094 with an integer argument which indicates which argument of section-type
2095 command is being read. Thus the add-in should determine the
2096 job referring the value of its argument.
2098 @dfn{enclosing add-in} is for modifying and/or checking the region that
2099 will be enclosed by section-type commands via @kbd{[prefix] S}. An
2100 enclosing add-in function will be called with two arguments, beginning of
2101 the enclosed region and end of the region. Suppose you want to enclose
2102 the existing text @code{(a+b)/c} by @code{\frac@{@}}.
2104 @display
2105 a/c
2106 | |
2107 A B
2108 @end display
2110 You do set-mark-command at point A and then move to point B. Typing
2111 @kbd{[prefix] S} and input @code{frac} enclose the region like this;
2113 @display
2114 \frac@{a/c@}
2115 @end display
2117 Normally, the expression @code{a/c} is translated to
2118 @code{\frac@{a@}@{c@}}. An enclosing add-in is useful for modifying
2119 @code{/} to @code{@}@{}.

2202 @subsection How the function is called
2204 YaTeX calls the add-in functions for specified begin-type, section-type,
2205 and maketitle-type command, if any. `Option add-in' functions for
2206 begin-type are called when @code{\begin@{ENV@}} has been inserted,
2207 functions for section-type are called just before input of the first
2208 argument, and functions for maketitle-type is called after maketitle-type
2209 command has been inserted. `Argument add-in' functions are called at each
2210 entry of arguments for section-type commands.

2261 @section Add-in generator
2263 First, don't forget to read the section of add-in functions @ref{Add-in
2264 functions}. If you easily understand how to define them, there's no need
2265 to read this section. But being not familiar with Emacs-Lisp, when you
2266 don't have clear idea what to do, this section describes how to get YaTeX
2267 make add-in function.
2269 There are two methods of generation. One is for fully interactive
2270 generator for beginners and another requires little knowledge of
2271 Emacs-Lisp.
2273 @subsection Generator for beginners
2274 The former generator is called by
2275 @center @kbd{M-x YaTeX-generate}
2277 @noindent
2278 strokes. All you have to do is follow the guidances. Defying them may cases
2279 the disaster (I wonder what is it???). So when you make some mistake, it
2280 is recommendable to type @kbd{C-g} and start afresh.
2282 @subsection Simple generator
2284 The latter generator is invoked by the next sequence.
2285 @center @kbd{M-x YaTeX-generate-simple}
2286 This generator can make both ``option add-in'' and ``argument add-in''
2287 (@emph{refer the section add-in functions}
2288 @ref{How the add-in function works}), whereas @code{YaTeX-generate}
2289 cannot make ``argument addin''.
2291 For example, assume you have the LaTeX command as follows.
2293 @example
2294 \epsinput[t](250,50)@{hoge.eps@}@{plain@}@{Picture of foo@}
2295 (A) (B) (1) (2) (3)
2296 (A)Optional parameter to specify the position
2297 One of t(top), b(bottom), l(left), r(right)
2298 (B)Maximum size of frame
2299 (1)1st argument is filename of EPS file
2300 (2)2nd argument indicates
2301 plain do nothing
2302 frame make frame around image
2303 dframe make double-frame around image
2304 for included EPS file.
2305 (3)Caption for the picture
2306 @end example
2308 Now get start with generation. Typing @kbd{M-x YaTeX-generate-simple}
2309 brings the prompt:
2310 @display
2311 (O)ption? (A)rgument?
2312 @end display
2314 @subsubsection Generating ``option add-in''
2315 @cindex option add-in
2317 Since (A), (B) above are optional argument, all we have to do to
2318 complete them is define the option add-in for them. Let's generate the
2319 function to complete (A).
2321 @display
2322 M-x YaTeX-generate-simple RET
2323 epsinput RET
2324 o
2325 @end display
2327 @noindent
2328 Typing as above leads the next prompt.
2330 @display
2331 Read type(1): (S)tring (C)omplete (F)ile ([)option (P)osition co(O)rd. (q)uit
2332 @end display
2334 @noindent
2335 This asks that ``Which type is the completion style of 1st argument?''.
2336 Here are the possible completion style.
2338 @table @code
2339 @item String
2340 read plain string
2341 @item Complete
2342 read with completion
2343 @item File
2344 read file name
2345 @item Option
2346 read optional string (if string omitted, omit [] too)
2347 @item Position
2348 read positional option (like [htbp])
2349 @item Coord.
2350 read coordinates
2351 @item Quit
2352 quit from generating
2353 @end table
2355 Since (A) is the optional argument to specify the location of included
2356 EPS file, the completion style is @code{Position}, and the possible
2357 characters are t, b, l, and r. To tell these information to generator,
2358 operate as follows.
2360 @display
2361 Read type(1).... p
2362 Acceptable characters: tblr RET
2363 @end display
2365 (B) is coordinate. So its completion style is coOrd. We want a prompt
2366 meaning ``Maximum size'' when completion.
2368 @display
2369 Read type(2).... o
2370 Prompt for coordinates: Max size RET
2371 @end display
2373 That's all for optional argument. Select quit.
2375 @display
2376 Read type(3).... q
2377 @end display
2379 Then the generated option add-in function for \epsinput will be shown in
2380 the next window.
2382 @subsubsection Generating ``argument add-in''
2383 @cindex argument add-in
2385 Next, create the argument add-in. The arguments for \epsinput are EPS
2386 file name, framing style, and caption string in sequence.
2388 @display
2389 M-x YaTeX-generate-simple RET
2390 epsinput RET
2391 a
2392 @end display
2394 Above key strokes bring the prompt that asks the number of argument.
2395 Answer it with 3.
2397 @display
2398 How many arguments?: 3 RET
2399 @end display
2401 Then the generator asks the completion style and prompt for completion.
2402 Answer them. @kbd{f} for FileName and prompt string.
2404 @display
2405 Read type(1).... f
2406 Prompt for argument#1 EPS file name RET
2407 @end display
2409 The second argument is one of selected symbol. So the completion type
2410 is @code{Completion}.
2412 @display
2413 Read type(2).... c
2414 Prompt for argument#2 Include style RET
2415 @end display
2417 Then all the candidates ready to be read. Type single RET after
2418 entering all.
2420 @display
2421 Item[1](RET to exit): plain RET
2422 Item[2](RET to exit): frame RET
2423 Item[3](RET to exit): dframe RET
2424 Item[4](RET to exit): RET

2427 The following prompt asks whether the entered string must belong to
2428 candidates or not. In this case, since the argument must be one of
2429 @code{plain}, @code{frame}, and @code{dframe}, type @code{y}.
2431 @display
2432 Require match? (y or n) y
2433 @end display
2435 The last argument is the caption string for which any completion is
2436 needed.
2438 @display
2439 Read type(3).... s
2440 Prompt for argument#3 Caption RET
2441 default: Figure of RET
2442 @end display
2444 Finally we'll get the argument add-in in the next window.

2448 If you get your own pretty function and you let it be in public, please
2449 steel yourself in the happy atmosphere and do not send me the function.
2450 I do know it is not fine because it is generated by yatexgen:-p.

2456 The standard completion tables provided in @file{yatex.el} contain a
2457 few La@TeX{} commands I frequently use. This is to lessen the key
2458 strokes to complete entire word, because too many candidates
2459 rarely used often cause too many hits. Therefore always try to
2460 use completion in order to enrich your dictionary, and you will
2461 also find `Wild Bird' growing suitable for your La@TeX{} style.
2463 The package name `Wild Bird' is the English translation of Japanese
2464 title `Yachou', which is a trick on words of Japanese.
