In substance + this package is a poor man solution to the task of typesetting + math fulfilling the ISO regulations "for physical sciences and technology" (formerli regulations ISO 31/XI, now ISO\,80000). + These regulations refer mostly to the family, series and shape + of fonts to be used with symbols of various nature. + +This package gets inspiration from the ISOmath package by Günter +Milde, but tries to get the same results without using any math +[font] groups (or families). As pdfLaTeX users may recall, this +typesetting program may se at maximum 16 math [font] groups (or +math font families); sometimes this number results in an error +that forbids the user to use the symbols s/he needs. + +The trick used in this package consists in employing text fonts +within the \text command (defined by the amsmath package that, therefore, is a dependence to which pmisomath is subjected) and +chose text font families, series, and shapes to be used within +that command argument. + +The commands are such as to fulfil some math requirements; for +example while in the scope of the \boldmath declaration, the +series is automatically set to bold without any user intervention. +The font size is automatically taken care by \text, so that fonts +have the correct size also while typesetting exponents or subscripts. + +Nevertheless, through proper advanced command options, the user +remains the person principally responsible of using the right +font for the right symbol in a document that must fulfil the +ISO regulations. + +This package is usable only with pdfLaTeX; LuaLaTeX and XeLaTeX +can access OpenType math fonts through the package unicode-math, +and with the "math-style=ISO" option they have the math switching +commands agree with the ISO regulations. + +pdfLATeX users have available some packages to fulfil the ISO requirements; principally the ISOmath package thet is subject +to a number of limitations due the the particular math environment +of the user, and libertinust1math that produces a complete set-up +with math fonts that match very well text fonts that are darker +than the standard default Computer Modern ones (including the +CM-super and the Latin Modern ones). + +This package works very well with the Latin Modern fonts; in +practice in math mode it uses the same Latin text fonts, and +the corresponding families, series, and shapes of the LGR +encoded CBfonts; it may work also with the CM and the CM-super +fonts, but the original author never uses them, therefore he +cannot guarantee any suitable result. + +For installation of this package, simply run the pmisomath.dtx +through pdfLaTeX (and only pdfLaTeX); move the produced sty file +to the .../tex/latex/pmisomath/ folder; if it does not exist, +create it; similarly move pmisomath.dtx to .../source/latex/pmisomath/ +and pmisomath.pdf to .../doc/latex/pmisomath/. + + + diff --git a/Master/texmf-dist/doc/latex/pm-isomath/manifest.txt b/Master/texmf-dist/doc/latex/pm-isomath/manifest.txt new file mode 100644 index 00000000000..cefa22bcf99 --- /dev/null +++ b/Master/texmf-dist/doc/latex/pm-isomath/manifest.txt @@ -0,0 +1,34 @@ +This is the manifest.txt file that accompanies the package PM-ISOmath, +version 1.00 of 2017 + +Original author: Claudio Beccari, 2017 + +This work may be distributed and/or modified under the conditions +of the LaTeX Project Public License, either version 1.3 of this +license or (at your option) any later version.

There exist some +% facilities, but sometimes they do not work. +% +% This package provides some robust work-arounds to bypass the +% difficulties experienced by some \pdfLaTeX\ users. +% \end{abstract} + +% \section{Introduction} +% The ISO regulations (formerly ISO\,31/XI, now ISO\,80000) are +% stringent rules to typeset mathematics in the domains of physics +% and applied sciences; their title explicitly mentions ``physics +% and technology'', but their careful reading let understand that +% they apply to alla sciences that use the ``mathematics of +% quantities''. Such entities form a special group or space, +% where the elements are couples of two ordered elements $(x, y)$, +% where $y$ represents the unit of measure and $x$ represents the +% ratio of the quantity to the unit of measure. Such paired +% elements may not e separated, therefore some special +% mathematical rules are established in order to operate on +% such entities. +% +% Add to these special mathematical bases the facto that the +% measure component of the quantity is pretty fuzzy and it +% is always accompanied by a certain degree of uncertainty; +% metrologists are the the masters in measuring quantities +% and handling their measures and uncertainties, but although +% for simplicity measures are handled by lay people as rational +% numbers (after all aren't the the ratio of something to be +% measured and the unit of measure?) we are facing the domain +% of fuzzy sets. +% +% Furthermore quantities are so many that any work in applied +% sciences should contain a nomenclature list in order to +% explain which symbol is used for which quantity. This is +% where the ISO regulations set some order and they published +% a long list of named quantities with their preferred symbols +% and their ``normal'' units according to the prescriptions +% of the Comité International des Pois et Mésures, that +% established the the International System of measures +% (Systhème International, SI). +% +% This ISO nomenclature is used uniformly by most, if not all, +% people involved in applied sciences; therefore among the few +% letters of the Latin and Greek alphabets almost none is free +% to be used for other purposes. +% +% This means that the usual math italic alphabet can be used for +% very few symbols if confusion is to be avoided. Other series +% and shapes must be judiciously used and the ISO regulations +% say how. +% +% There are no problems when typesetting applied science +% documents with \LuaLaTeX\ or \XeLaTeX, at least if the +% proper OpenType math fonts are used; Such fonts have +% available so mani slots (code points) that may contain +% any variation of any glyph; it suffices to specify the +% option |math style = ISO| to the math handling package +% |unicode-math| and to select an OpenType math font. The +% only problem, if any, is to know which font series and +% shapes should be used according to the ISO regulations. +% +% These regulations can be purchased from the ISO site in +% Switzerland; they are quite expensive and the cost is +% affordable by associated professional studios or large +% academic and/or research institutions. +% +% For private users I'd suggest to download the PDF document +% \url{https://www.nist.gov/pml/special-publication-811-extended-%contents}. This document has been produced by the National +% Institute for Science and Technology, the Institutions that +% several years ago was appointed to replace the United States +% National Bureau of Standards. Thei staff is made essentially +% by metrologists and this guide is written to give precise +% instructions for handling the applied science mathematics +% according to the ISO Regulations; Is establishes also several +% rules for writing text about mathematics and metrology. It +% is extremely valuable for anglophones, but, with the due +% differences concerning the mother languages, it is extremely +% useful also for people using other languages than English. +% +% \section{The \pdfLaTeX\ handicaps} +% Users of \pdfLaTeX, on the opposite are in trouble. In facts +% this typesetting program suffers from an inherited limitation: +% math fonts are encoded with the old 128 glyph encodings; this +% is not a limitation set forth by the underlying interpreter +% \pdfTeX. Matter of fact there exist the quite recent +% LibertinusT1math fonts for \pdfLaTeX, created by Michal Sharpe, +% that to my best knowledge are the only ones with 256 glyph +% encodings. Package |libertinust1math| accepts the |ISO| option +% that allows to fulfil the ISO regulations; it accepts other +% options depending on which the number of math groups, beyond +% the essential first four ones, increases by three to six units, +% reaching a maximum of ten; there remains enough free math +% groups to satisfy any user requirement. +% +% But even while using such LibertinusT1math fonts, \pdfTeX\ +% suffers from another handicap derived from the knuthian +% original \TeX-the-program and by the NFSS (New FonT Selection +% Scheme, which is not new any more, because it dates back to +% 1994, when \LaTeX\,209 became obsolete and was substituted +% by \LaTeXe.). I am not complaining about these \pdfTeX\ and +% \LaTeX\ limitations; for decades people have been happily +% typesetting math with results that are much superior to any +% other typesetting program if it does not use some \TeX\ software. +% +% The handicap I am talking about is the way math alphabets are +% handled at the moment by \pdfTeX and \LaTeX; such alphabets +% are loaded in the form of math groups, the number of which +% cannot exceed 16 (numbered from 0 to 15); each group loads +% three sizes for normal math style, for script style and for +% script-script style. +% +% By default four groups are always loaded; group~0 for +% operators; group~1 for letters; group~2 for symbols; +% group~3 for large operators and delimiters; users very +% often load also the two symbol-fonts provided by the +% American Mathematical Society, and this means two more +% math groups. Apparently there are ten more groups for +% other math groups. It seems that this number is abundantly +% sufficient to handle any situation, but it is not so. The +% author of this extension already reached the limit of~16 +% without doing anything special -- at least he thought so, +% but he was evidently wrong. Users who use packages such +% as the Fourier or the KPfonts have to pay special attention +% to their documentation because they might specify options +% that imply loading up to 14 math groups. +% +% Several authors provided packages to help users produce +% perfect documents that fulfil the ISO regulations; I would +% like to cite the excellent Package|ISOmath| by Günter Milde, +% entitled ``Mathematical style for science and technology''. +% It should be the perfect package to use in order to fulfil +% the ISO regulations; sometimes it succeeds with excellent +% results, but more often than not the results are just partial, +% because of the limitations of the math fonts available to +% \pdfLaTeX\ that are in contrast with the requirements of +% the ISO regulations. +% +% Therefore, dear reader, before using the poor man solutions +% of this package, try |ISOmath|, if your font set passes all +% the requirements described in this package documentation, +% you don't need the poor man patches offered by this package. +% +% \section{ISO rules summary} +% This summary does not replace the original ISO document nor +% what is written in the instructions published by NIST. It +% simply recalls those rules that this package tries to implement. +% In the following the word ``quantity'' is used to represent +% any physical entity that may be measured according to the +% metrological standards; the word ``variable'' is used to +% represent a mathematical entity that represents variable data. +%\begin{enumerate}[noitemsep] +% \item +% All quantity and variable symbols are represented by one +% letter (with as many appositions are needed); but no acronyms +% are allowed; in computer science programming many strings +% are called variables, in the sense that they may represent +% variable data; but computer programs are not mathematics, +% rather they are a special language that tells the computer +% what to do, even mathematics, but the language is not the +% one that represents math. Unfortunately som acronyms have +% gained strong popularity and wide usage, but they are +% forbidden by the ISO rules; example: \emph{CMRR} is often +% used to mean ``common mode rejection ratio'', but this is +% an improper usage of mathematics. Obviously this rule +% must be applied by the user, because \LaTeX\ is a +% typesetting language and does not understand the real +% meaning of what it typesets. +% \item +% All quantity symbols must be set in italics, slanted type +% is allowed, but serifed italics should be referred, unless +% the ISO rules prescribe a sans serif font. This implies that +% the differential symbol be in upright font to avoid confusion +% with the physical quantity $d$; the Napier number `e' must be +% set in upright font to avoid confusion with the elementary +% electric charge $e$; the imaginary unit j in electrical +% engineering, i in other applied sciences) be in upright font +% in order to avoid confusion with the electric current density +% $j$ or the electric current $i$; more difficult: the +% transcendental number $\ISOpi=3.14159\dots$ be distinguished +% from the plane angle $\pi$; and similar other numerical constants represented by Latin or Greek letters. +% \item +% All symbols that do not represent quantities should be +% typeset in an upright font, preferably a serifed font, +% except when the ISO rules require a sans serif font. +% This rule include numbers and their digits, symbols that +% represent constant numeric values, all appositions both +% in subscript and superscript position. Appositions are not +% quantities or variables: for example in $V_i$, the +% subscript $i$ is a variable because it represents the $i$-th +% element in a sequence, such as $V_0, V_1, V_2, \dots$; on +% the opposite $V_{\mathrm{i}}$ is an apposition because `i' +% means, say, `input'. +% \item +% Upright bold roman or black board bold symbols represent sets. +% \item +% Italic bold symbols represent matrices; une column matrices +% may represent vectors in an algebraic way and should be +% treated as any other matrix; generally multirow and multicolumn +% matrices are typeset with uppercase letters, while lowercase +% ones are reserved for vectors; but in some sciences also vectors +% may have uppercase letters. Geometrical vectors that might be +% typeset wit a medium series upper o lowercase italic letter +% with an arrow on top of it are nor treated by the ISO +% regulations that speak of vectors irrespective if they are +% considered as one column matrices od oriented segments; +% apparently oriented segments should be treated the same as +% one column matrices. +% \item +% Labels to geometrical entities, such as points, segments, +% angles (not their measures) should be set in upright +% medium series sans serif fonts; the same rule applies +% to labels used in sketches and drawings representing +% machinery, electric circuitry, and the like when the label +% refers to an object and not to its measure: ``the lens +% $\mathsf{L}_1$'', ``the switch $\mathsf{S}_2$'', ``the +% planetary gear $\mathsf{G}_3$'', and so on. +% \item +% Tensors should be set in slanted bold sans serif font. +% \item +% The above rules apply to both Latin and Greek +% letters.\label{enum:latin-greek} +%\end{enumerate} +% +% Such font rules for families, series and shapes are difficult +% to implement with \pdfLaTeX\ for many reasons that do not imply +% only the limited number of math groups, but also the categories +% of symbols; Greek letters in particular are troublesome for a +% couple of reasons connected with rule~\ref{enum:latin-greek}: +%\begin{itemize}[noitemsep] +%\item +% Uppercase greek letters are taken from the ``operators'' +% alphabet and are letter symbols; therefore they are upright; +% but if they represent quantities they must be in italics, +% or at least slanted; +%\item +% Lowercase Greek letters are taken from the ``letters'' alphabet +% and are ordinary symbols; they are slanted, and this is fine, +% but as ordinary symbols they cannot be modified by commands +% such as |\mathrm|; furthermore upright lowercase Greek letters +% are not available. +%\end{itemize} +% +% \section{Some existing solutions} +% Several packages to be used with \pdfLaTeX\ allow for upright +% Greek letters, especially those packages for French typography, +% where the national rules (in contrst with the ISO regulations) +% require that all math entities typeset with Greek letters be +% upright. Among these the |fourier| and the |kpfont|. Other +% packages such as |newpxmath| and |newtxmath| are intended for +% general use, but with suitable options and extra math groups +% let the user employ upright lowercase letters as well as +% slanted uppercase ones. +% +% Package |libertinust1math| allows the use of the 256~glyph +% encoded fonts and are less sensitive to the limit of 16~math +% groups, Is many options allow to use the various font styles +% without requiring the |\boldmath| declaration; this implies +% that medium and bold series are both preloaded without +% actually using extra math alphabets beyond the small number +% it uses for its full functionality. An option |ISO| is +% already available to fulfill the ISO regulations. Maybe +% the only drawback of the fonts used is that they match text +% fonts that are blacker than the standard Computer or Latin +% Modern fonts. The auxiliary font selection commands used in +% the |ISOmath| package are already implemented with this +% |libertinust1math| one. +% +% Of course the |ISOmath| package might solve all problems if the +% user math environment has the necessary functionalities, in +% particular all the math alphabets needed for the task and +% there are no difficulties with the number of math groups. +% +% \section{The poor man solution} +% The poor man solution is very simple in theory; it handles +% text fonts in math expressions through the |\text| command +% of the |amsmath| package; of course there are functionalities +% to chose families series and shapes in a comfortable way +% by means of the powerful command definition commands provided +% by the |xparse| package; for Greek letters it uses the +% functionalities of the |alphabeta| package, that allows to use +% in text mode the same control sequences that are used +% in math mode. The default families for Latin and Greek letters +% are the Latin Modern ones that allow a piecewise continuous +% scaling of any available particular font of the collection. +% +% Needless to say, this poor man solution has advantages and +% disadvantages over the other indicated solutions. +% +% The main advantage is that no math groups are involved, +% therefore the user may couple any font family with any +% series and shape that family allows; the default +% family for Greek fonts are the Latin Modern compliant +% LGR encoded collection of CBfonts; they are always +% available with any updated and complete \TeX\ system +% installation. +% +% This is also a disadvantage, in the sense that Latin Modern +% fonts might not be the best ones to use with any specific +% text font; for example they have an x-height smaller than +% the Palatino ones, and a larger `em' unit compared to the +% Times ones; they have also a slightly lighter `color' +% than most other fonts. +% +% Nevertheless they work very well with the ISO regulations +% and in spite of the disadvantages listed above, they are +% usable without problems. 'This documentation is typeset +% with Latin Modern fonts and this very package. The examples +% shown in a following chapter show the ease with which the +% ISO regulations may be fulfilled. +% +% There are other Greek fonts that may be used in place if +% those of the CBfonts collection, especially those distributed +% by the Greek Font Society (GFS) that are already part of the +% \TeX\ system distribution; they are LGR encoded and have their +% specific |.fd| files. They are not so rich in series and shapes +% (some of them may lack the bold extended series and sometimes +% lack also the bold series); I would say the the GFS Bodoni +% family is sufficiently rich of series and shapes, and may be used +% also for the Latin fonts. +% +% There are also the Greek fonts that are ``companions'' to the +% Times fonts. So the user is not limited to the Latin Modern +% fonts, but admittedly there is not a great choice and, if it +% is necessary, the disadvantage of an unmatching Greek font is +% the price to pay if the user has to use \pdfLaTeX. +% +% \section{Usage} +% The usage of the package is very simple; in your preamble +% add the line +%\begin{ttsintassi} +%\cs{usebackage}\Oarg{engineer}\Marg{pm-isomath} +%\end{ttsintassi} +% The |engineer| option is used to set the imaginary unit the +% way electrical engineers usually do. +% +% The main macros that support the whole package, and that may +% be used also by the end user, are: +%\begin{ttsintassi} +%\cs{MathLatin}\marg{letter}\marg{family}\oarg{series}\parg{shape} +%\end{ttsintassi} +%and +%\begin{ttsintassi} +%\cs{MathGreek}\marg{letter}\marg{family}\oarg{series}\parg{shape} +%\end{ttsintassi} +% where \cs{MathLatin} sets the text encoding to |T1|, while +% \cs{MathGreek} set it to |LGR|. In both commands the arguments +% specified with \marg{family}\oarg{series}\parg{shape} are all +% optional, including the first one in spite of being surrounded +% by curly braces. In both cases the default values for each +% argument are respectively |lmr|, |m|, and |n| (normal upright). +% +% Such default values, after loading |pm-isomath|, may be globally +% redefined by using in the preamble: +%\begin{ttsintassi} +%\cs{renewcommand}\Marg{ISOfam}\marg{family} +%\cs{renewcommand}\Marg{ISOser}\marg{series} +%\cs{renewcommand}\Marg{ISOsha}\marg{shape} +%\end{ttsintassi} +% We discourage this global redefinitions unless the user really +% knows what s/he is doing; in practice it must be checked that +% T1 encoded families and LGR encoded ones have the same family +% names. If the encoding+family|.fd| files are not available +% either they have to be created, or such default values should +% not be redefined. +% +% For Latin letters to use in the |\MathLatin| command mandatory +% argument there are no problems. +% +% For Greek letters you might use the math commands |\alpha|, +% |\beta|,\dots, |\Omega| commands, but it is much simpler to +% use the package commands |\ISOalpha|, |\ISObeta|,\dots, +% |\ISOOmega|. All these commands follow the syntax: +%\begin{ttsintassi} +%\cs{ISO}\meta{lettername}\marg{family}\oarg{series}\parg{shape} +%\end{ttsintassi} +% where all the arguments are optional, including the first in +% spite of being surrounded by curly braces.

It has +% the indubitable advantage that is does not use any math group, +% therefore there is no risk to exceed the limit of 16~math groups. +% +% \StopEventually{} +% +% \section{The code} +% This package was loosely inspired by the |ISOmath| package +% by Günter Milde, but tacles the problem of insuffiente maximum +% number of math font groups so as to avoid any problem with such +% groups, and therfore all the caveats in Milde's package. That +% package is much more comfortable to use then this one; but +% it is subject to a number of conditions the, depending on the +% user environment, may even result in a complete failure. This +% package avoids problema with math font groups because it does +% not use any, but it is not so comfortable to use because often +% the user has to specify optional settings. +% +%The preliminary lines have been already defined; therefore we +% start with real code. +% +%The trick of this package is that all fonts different from the +% four or six (including the AMS symbol fonts) are textual fonts +% used in math typesetting through the intermediate action of +% the |\text| command defined by the |amsmath| package. +% Therefore we start by verifying if packages |amsmath|, +% |alphabeta| and |xparse| have already been loaded by in the +% preamble document; this implies a weak loading order, that is this +% package must be loaded after all the above packages are loaded; +% in facts of such packages are not loaded, they are by this +% package, and they are loaded without options. The package +% loading mechanism assures avoiding conflicts if packages are +% loaded without options; this is why if one of the three packages +% is loaded after this one but with some option specified an +% ``Option clash"" error flag is raised; this is where the +% ``weak'' loading error becomes an very ``strong'' one. + +%\iffalse +%<*style> +%\fi +% \begin{macrocode} +% The we verify if the document is being typeset with \pdfLaTeX; +% it it is not; and error flag is raised and reading of this +% package is immediately interrupted.

In spite of this option driven aliases, both +% commands |\iunit| and |\junit| are stille available to the +% user. +% +% The Napier number `e' is defined in roman type, but as an +% operator; this number is not an operator in the mathematical +% sense, but it is most often uses as the base of an exponential; +% therefore such mathematica ``atom'' must be treated as an +% operator as well as when the official operator macro |\exp| +% is used. +% +% The transcendental number $\ISOpi$, different from the plane +% angle $\pi$, is defined so as to be typeset in upright +% style; similar definitions may be used for other numerical +% constants; we define just |\uppi| because we think it is the +% most used symbol in any kind of mathematics. The +% $\ISOpi{lmss}(n)$ Greek letter in upright sans serif font +% may indicate the subatomic particle ``pion'' so that a +% similar macro, say, |\sspi| or, more expressively, |\pion| +% may be given a suitable definition. +% +% The differential symbol is not an operator, but it requires +% a special treatment; a macro |\diff| for the differential +% symbol uses an empty`operator' and a negative shift to typeset +% an upright letter `d' with an operator spacing on its left, +% so that proper spacing is used in math typesetting; Notice +% that the given definition does not perform as the direct +% use of a thin math space before the upright `d', because +% spacing bteween math atoms depends on their category, while +% the thin space |\,| is absolute and does not change depending +% on the preceding math atom. +% +% The command |\unit| for appending the units of measure to +% the numerical value of the measure is added if no packages +% have already defined it; package |siunitx| is a particularly +% recommended one. Similar considerations hold true for the +% |\ap| and |\ped| (apex and pedex, respectively; i.e\ +% superscript and subscript); therefore such command definitions +% are deferred to the start of the document so as to be sure +% to avoid damaging other package settings. All these commands +% may be used in both text and math modes; therefore a robust +% macro |\textormath| is (re)defined even if often such command +% is already available; the |\DeclareRobustCommand| unconditionally +% declares and redeclares robust commands even if they are +% already defined; possibly an information line is written in +% the |.log| file in case a redefinition takes palace.
