NAME

       autoinst - wrapper around the LCDF TypeTools, for installing and using OpenType fonts in
       LaTeX.

SYNOPSIS

       autoinst -help

       autoinst [options] font(s)

DESCRIPTION

Eddie Kohler's LCDF TypeTools are superb tools for installing OpenType fonts in LaTeX, but
they can be hard to use: they need many, often long, command lines and don't generate the
fd and sty files LaTeX needs. autoinst simplifies the use of the TypeTools for font
installation by generating and executing all commands for otftotfm, and by creating and
installing all necessary fd and sty files.

Given a family of font files (in otf or ttf format), autoinst will create several LaTeX
font families:

- Four text families (with lining and oldstyle digits, each in both tabular and
proportional variants), all with the following shapes:

n Roman (i.e., upright) text

it, sl Italic and slanted (sometimes called oblique) text

sc Small caps

scit, scsl
Italic and slanted small caps

sw Swash

nw "Upright swash"

- For each T1-encoded text family: a family of TS1-encoded symbol fonts, in roman,
italic and slanted shapes.

- Families with superiors, inferiors, numerators and denominators, in roman, italic and
slanted shapes.

- Families with "Titling" characters; these "... replace the default glyphs with
corresponding forms designed specifically for titling. These may be all-capital
and/or larger on the body, and adjusted for viewing at larger sizes" (according to
the OpenType Specification).

- An ornament family; also in roman, italic and slanted shapes.

Of course, if your fonts don't contain italics, oldstyle digits, small caps etc., the
corresponding shapes and families are not created. In addition, the creation of most
families and shapes can be controlled by the user (see "COMMAND-LINE OPTIONS" below).

These families use the FontPro project's naming scheme: <FontFamily>-<Suffix>, where
<Suffix> is:

LF proportional (i.e., figures have varying widths) lining figures

TLF tabular (i.e., all figures have the same width) lining figures

OsF proportional oldstyle figures

TOsF tabular oldstyle figures

Sup superior characters (note that most fonts have only an incomplete set of superior
characters: digits, some punctuation and the letters abdeilmnorst; normal forms
are used for other characters)

Inf inferior characters; usually only digits and some punctuation, normal forms for
other characters

Titl Titling characters; see above

Orn ornaments

Numr, Dnom
numerators and denominators

The individual fonts are named <FontName>-<suffix>-<shape>-<enc>, where <suffix> is the
same as above (but in lowercase), <shape> is either empty, "sc" or "swash", and <enc> is
the encoding (also in lowercase). A typical name in this scheme would be
FiraSans-Light-osf-sc-ly1.

Using the fonts in your LaTeX documents
autoinst generates a style file for using the fonts in LaTeX documents, named
<FontFamily>.sty. This style file also loads the fontenc and textcomp packages, if
necessary. To use the fonts, add the command "\usepackage{<FontFamily>}" to the preamble
of your document.

This style file has a few options:

"mainfont"
Redefine "\familydefault" to make this font the main font for the document. This is a
no-op if the font is installed as a serif font; but if the font is installed as a
sanserif or typewriter font, this option saves you from having to redefine
"\familydefault" yourself.

"lining", "oldstyle", "tabular", "proportional"
Choose which figure style to use. The defaults are "oldstyle" and "proportional" (if
available).

"scale=<number>", "scale=MatchLowercase"
Scale the font by a factor of <number>. E.g., to increase the size of the font by 5%,
use "\usepackage[scale=1.05]{<FontFamily>}". The special value "MatchLowercase" may
be used to scale the font so that its x-height matches that of the current main font
(which is usually Computer Modern Roman, unless you have loaded another font package
before this one). The name "scaled" may be used as a synonym for "scale".

"medium", "book", "text", "normal", "regular"
Select the weight that LaTeX will use as the "regular" weight.

"heavy", "black", "extrabold", "demibold", "semibold", "bold"
Select the weight that LaTeX will use as the "bold" weight.

The last two groups of options will only work if you have the mweights package installed.
The default here is not to change LaTeX's default, i.e. use the "m" and "b" weights.

The style file will also try to load the fontaxes package (on CTAN), which gives easy
access to various font shapes and styles. Using the machinery set up by fontaxes, the
generated style file defines a number of commands (which take the text to be typeset as
argument) and declarations (which don't take arguments, but affect all text up to the end
of the current group) to access titling, superior and inferior characters:

DECLARATION COMMAND SHORT FORM OF COMMAND

\tlshape \texttitling \texttl
\supfigures \textsuperior \textsup, \textsu
\inffigures \textinferior \textinf, \textin

In addition, the existing "\swshape" and "\textsw" commands are redefined to place swash
on fontaxes' secondary shape axis (fontaxes places it on the primary shape axis) to make
them behave properly when nested, so that "\swshape\upshape" will give upright swash.

There are no commands for accessing the numerator and denominator fonts; these can be
selected using fontaxes' standard commands, e.g.,
"\fontfigurestyle{numerator}\selectfont".

These commands are only generated for existing shapes and number styles; no commands are
generated for shapes and styles that are missing from your fonts. Also these commands are
built on top of fontaxes, so if that package cannot be found, you're limited to using the
lower-level commands from standard NFSS ("\fontfamily", "\fontseries", "\fontshape" etc.).

By default, autoinst generates text fonts with OT1, LY1 and T1 encodings, and the
generated style files use T1 as the default text encoding. Other encodings can be chosen
using the -encoding option (see "COMMAND-LINE OPTIONS" below).

Maths
This is an experimental feature; USE AT YOUR OWN RISK! Test the results thoroughly before
using them in real documents, and be warned that future versions of autoinst may introduce
incompatible changes.

The -math option tells autoinst to generate basic math fonts. When enabled, the generated
style file defines a few extra options to access these math fonts:

"math"
Use these fonts for the maths in your document.

"mathlining", "matholdstyle"
Choose which figure style to use in maths. The default is "mathlining".

"mathcal"
Use the swash characters from your fonts as the "\mathcal" alphabet. (This option
will only exist if your fonts actually contain swash characters, plus a "swsh" feature
to access them).

"nomathgreek"
Don't redeclare greek letters in math.

"math-style=<style>"
Choose the "math style" to use. With "math-style=ISO", all latin and greek letters in
math are italic; with "math-style=TeX" (the default), uppercase greek is upright; with
"math-style=french", all greek as well as uppercase latin is upright; and with
"math-style=upright" all letters are upright.

Note that this "math" option only affects digits, latin and greek letters, plus a few
basic punctuation characters; all other mathematical symbols, operators, delimiters etc.
are left as they were before. If you don't want to use TeX's default versions of those
symbols, load another math package (such as mathdesign or newtxmath) before loading the
autoinst-generated style file.

Finally, note that autoinst doesn't check if your fonts actually contains all of the
required characters; it just assumes that they do and sets up the style file accordingly.
Even if your fonts contain greek, characters such as "\varepsilon" may be missing. You
may also find that some glyphs are present in your fonts, but don't work well in equations
or don't match with other symbols; edit the generated style file to remove the
declarations of these offending characters. Once again: test the results before using
them! If the characters themselves are fine but spaced too tightly, you may try
increasing the side bearings in math fonts with the -mathspacing option (see below), e.g.
"-mathspacing=50".

NFSS codes
LaTeX's New Font Selection System (NFSS) identifies fonts by a combination of family,
series (the concatenation of weight and width), shape and size. autoinst parses the
font's metadata to determine these parameters. When this fails (usually because the font
family contains uncommon weights, widths or shapes), autoinst ends up with multiple fonts
having the same values for these font parameters; such fonts cannot be used in NFSS, since
there's no way distinguish them. When autoinst detects such a situation, it will print an
error message and abort. If that happens, either rerun autoinst on a smaller set of
fonts, or add the missing widths, weights and shapes to the tables @WIDTH, @WEIGHT and
%SHAPE in the source code. Please also send a bug report (see AUTHOR below).

The mapping of shapes to NFSS codes is done using the following table:

SHAPE CODE
-------------------------------- ----
Roman, Upright n
Italic it
Oblique, Slant(ed), Incline(d) sl

(Exception: Adobe Silentium Pro contains two Roman shapes; we map the first of these to
"n", for the second one we (ab)use the "it" code as this family doesn't contain an Italic
shape.)

For weights and widths, autoinst tries to the standard NFSS codes (ul, el, l, sl, m, sb,
b, eb and ub for weights; uc, ec, c, sc, m, sx, x, ex and ux for widths) as much as
possible. Of course, not all 81 combinations of these NFSS weights and widths will map to
existing fonts; and conversely it may not be possible to assign every existing font a
unique code in a sane way (especially for the weights, some font families offer more
variants than NFSS's codes can handle; e.g., Fira Sans contains fifteen different
weights!). Therefore every font is also assigned a "series" name that is the
concatenation of its weight and width, after expanding any abbreviations and converting to
lowercase. A font of "Cond" width and "Ultra" weight will then be known as
"ultrablackcondensed".

The exact mapping between fonts and NFSS codes can be found in the generated fd files and
in the log file (you may want to run autoinst with the -dryrun option to check the chosen
mapping beforehand). The -nfssweight and -nfsswidth command-line options can be used to
finetune the mapping between NFSS codes and fonts.

To access specific weights or widths, one can always use the "\fontseries" command with
the full series name (i.e., "\fontseries{demibold}\selectfont").

Ornaments
Ornament fonts are regular LY1-encoded fonts, with a number of "regular" characters
replaced by ornament glyphs. The OpenType specification says that fonts should only put
their ornaments in place of the lowercase ASCII letters, but some fonts put them in other
positions (such as those of the digits) as well.

Ornaments can be accessed like "{\ornaments a}" and "{\ornaments\char"61}", or
equivalently "\textornaments{a}" and "\textornaments{\char"61}". To see which ornaments a
font contains (and at which positions), run LaTeX on the file nfssfont.tex (which is
included in any standard LaTeX installation), supply the name of the ornament font (i.e.,
"GaramondLibre-Regular-orn-u") and give the command "\table\bye"; this will create a table
of all glyphs in that font.

Note that versions of autoinst up to 20200428 handled ornaments differently, and fonts and
style files generated by those versions are not compatible with files generated by newer
versions.

WARNINGS AND CAVEATS

   OpenType fonts and licensing issues
       Since pdfTeX cannot subset otf-flavoured OpenType fonts, otftotfm will convert such fonts
       to Type1 (pfb) format.  However, many fonts (at least those licensed under the SIL Open
       Font License) do not allow distributing such converted versions under their original name.

       To meet these licensing requirements, autoinst provides a -t1suffix command-line option
       that appends a user-defined suffix to the names (both the filename and the internal font
       name) of all generated Type1 fonts; see "COMMAND-LINE OPTIONS" below.

   Sorry, LIGTABLE too long for me to handle
       The LIGTABLE in TeX's tfm files, which contains a font's ligatures and kerning pairs, is
       limited to about 32,500 entries (2^15 - 256).  If the number of ligatures plus kerns in a
       font is higher than that limit, pltotf and vptovf will complain loudly and ignore the
       excess entries.  This happens at least with Adobe's Source Serif 4 and Minion 3.  The best
       way to handle this situation is to use autoinst's "-extra" option to raise otftotfm's
       value for the "--min-kern" parameter, which causes it to ignore small kerning pairs:
       "-extra='--min-kern=5.0'".

   A note for MiKTeX users
       Automatically installing the fonts into a suitable TEXMF tree (as autoinst tries to do by
       default) only works for TeX-installations that use the kpathsea library; with TeX
       distributions that implement their own directory searching, such as MiKTeX, autoinst will
       complain that it cannot find the kpsewhich program and move all generated files into a
       subdirectory "autoinst_output/" of the current directory.  If you use such a TeX
       distribution, you should either move these files to their correct destinations by hand, or
       use the -target option (see "COMMAND-LINE OPTIONS" below) to manually specify a TEXMF
       tree.

       Also, some OpenType fonts contain so many kerning pairs that the resulting pl and vpl
       files are too big for MiKTeX's pltotf and vptovf; the versions that come with W32TeX
       (http://www.w32tex.org) and TeXLive (http://tug.org/texlive) don't seem to have this
       problem.

   A note for MacTeX users
       By default, autoinst will try to install all generated files into the $TEXMFLOCAL tree;
       when this directory isn't user-writable, it will use the $TEXMFHOME tree instead.
       Unfortunately, MacTeX's version of "updmap-sys" doesn't search in $TEXMFHOME, and hence
       MacTeX will not find the new fonts.

       To remedy this, either run autoinst as root (so that it can install everything into
       $TEXMFLOCAL) or manually run "updmap -user" to tell TeX about the files in $TEXMFHOME.
       This latter option does, however, come with some caveats; see
       https://tug.org/texlive/scripts-sys-user.html.

COMMAND-LINE OPTIONS

autoinst tries hard to do The Right Thing (TM) by default, so you usually won't need these
options; but most aspects of its operation can be fine-tuned if you want to.

You may use either one or two dashes before options, and option names may be shortened to
a unique prefix (e.g., -encoding may be abbreviated to -enc or even -en, but -e is
ambiguous (it may mean either -encoding or -extra)).

General options
-help
Print a (relatively) short help text and exit.

-dryrun
Don't generate output; just parse input fonts and write the results to the log file.

-verbose
Add more details to the log file.

-version
Print autoinst's version number and exit.

Font creation options
-encoding=encoding[,encoding]
Generate the specified encoding(s) for the text fonts. Multiple encodings may be
specified as a comma-separated list (without spaces!); the default choice of encodings
is "OT1,LY1,T1".

For each encoding argument, autoinst will first check if it is the filename of an
encoding file, and if found it will use that; otherwise the argument is assumed to be
the name of one of the built-in encodings. Currently autoinst comes with built-in
support for the OT1, T1/TS1, LY1, LGR, T2A/B/C and T3/TS3 encodings. (These files are
called fontools_ot1.enc etc. to avoid name clashes with other packages; the fontools_
prefix may be omitted.)

-ts1/-nots1
Control the creation of TS1-encoded fonts. The default is -ts1 if the text encodings
(see -encoding above) include T1, -nots1 otherwise.

-lining/-nolining
Control the creation of fonts with lining figures. The default is -lining.

-oldstyle/-nooldstyle
Control the creation of fonts with oldstyle figures. The default is -oldstyle.

-proportional/-noproportional
Control the creation of fonts with proportional figures. The default is -proportional.

-tabular/-notabular
Control the creation of fonts with tabular figures. The default is -tabular.

-smallcaps/-nosmallcaps
Control the creation of small caps fonts. The default is -smallcaps.

-swash/-noswash
Control the creation of swash fonts. The default is -swash.

-titling/-notitling
Control the creation of titling families. The default is -titling.

-superiors/-nosuperiors
Control the creation of fonts with superior characters. The default is -superiors.

-inferiors [ = none | auto | subs | sinf | dnom ]
-noinferiors
The OpenType standard defines several kinds of digits that might be used as inferiors
or subscripts: "Subscripts" (OpenType feature "subs"), "Scientific Inferiors"
("sinf"), and "Denominators" ("dnom"). This option allows the user to determine which
of these styles autoinst should use for the inferior characters. Alternatively, the
value "auto" tells autoinst to use the first value in "sinf", "subs" or "dnom" that is
supported by the font. Saying just -inferiors is equivalent to -inferiors=auto;
otherwise the default is -noinferiors.

If you specify a style of inferiors that isn't present in the font, autoinst will fall
back to its default behaviour of not creating fonts with inferiors at all; it won't
try to substitute one of the other styles.

-fractions/-nofractions
Control the creation of fonts with numerators and denominators. The default is
-nofractions.

-ligatures/-noligatures
Some fonts contain glyphs for the standard f-ligatures (ff, fi, fl, ffi, ffl), but
don't provide a "liga" feature to access these. This option tells autoinst to add
extra "LIGKERN" rules to the generated fonts to enable the use of these ligatures.
The default is -ligatures, except for typewriter fonts.

Specify -noligatures to disable generation of ligatures even for fonts that do contain
a "liga" feature.

-ornaments/-noornaments
Control the creation of ornament fonts. The default is -ornaments.

-serif/-sanserif/-typewriter
Install the font as a serif, sanserif or typewriter font, respectively. This changes
how you access the font in LaTeX: with "\rmfamily"/"\textrm", "\sffamily"/"\textsf" or
"\ttfamily"/"\texttt".

Installing the font as a typewriter font will cause two further changes: it will - by
default - turn off the use of f-ligatures (though this can be overridden with the
-ligatures option), and it will disable hyphenation for this font. This latter effect
cannot be re-enabled in autoinst; if you want typewriter text to be hyphenated, use
the hyphenat package.

If none of these options is specified, autoinst tries to guess: if the font's filename
contains the string "mono" or if the field "isFixedPitch" in the font's "post" table
is True, it will select -typewriter; else if the filename contains "sans" it will
select -sanserif; otherwise it will opt for -serif.

-math
Tells autoinst to create basic math fonts (see above).

-mathspacing=amount
Letterspace each character in the math fonts by amount units, where 1000 units equal
one em. In my opinion, many text fonts benefit from letterspacing by 50 to 100 units
when used in maths; some fonts need even more. Use your own judgement!

Output options
-t1suffix [ = SUFFIX ]
Tell autoinst to modify the font names of all generated Type1-fonts, by adding SUFFIX
to the family name. If you use this option without specifying a SUFFIX value,
autoinst will use the value "PS". The default behaviour when this option is not given
is to not modify font names at all.

See also "OpenType fonts and licensing issues" in "WARNINGS AND CAVEATS" above.

-target=DIRECTORY
Install all generated files into the TEXMF tree at DIRECTORY.

By default, autoinst searches the $TEXMFLOCAL and $TEXMFHOME trees and installs all
files into the first user-writable TEXMF tree it finds. If autoinst cannot find such
a user-writable directory (which shouldn't happen, since $TEXMFHOME is supposed to be
user-writable) it will print a warning message and put all files into the subdirectory
"autoinst_output/" of the current directory. It's then up to the user to move the
generated files to a better location and update all relevant databases (usually by
calling texhash and updmap).

-vendor=VENDOR
-typeface=TYPEFACE
These options are equivalent to otftotfm's --vendor and --typeface options: they
change the "vendor" and "typeface" parts of the names of the subdirectories in the
TEXMF tree where generated files will be stored. The default values are "lcdftools"
and the font's FontFamily name. These options change only directory names, not the
names of any generated files.

-logfile=filename
Write log data to filename instead of the default <fontfamily>.log. If the file
already exists, autoinst appends to it; it doesn't overwrite an existing file.

Specialist options
-defaultlining/-defaultoldstyle
-defaulttabular/-defaultproportional
Tell autoinst which figure style is the current font family's default (i.e., which
figures you get when you don't specify any OpenType features).

Don't use these options unless you are certain you need them! They are only needed
for fonts that don't provide OpenType features for their default figure style; and
even in that case, autoinst's default values (-defaultlining and -defaulttabular) are
usually correct.

-nfssweight=code=weight
-nfsswidth=code=width
Map the NFSS code code to the given weight or width, overriding the built-in tables.
Each of these options may be given multiple times, to override more than one NFSS
code. Example: to map the "ul" code to the "Thin" weight, use "-nfssweight=ul=thin".
To inhibit the use of the "ul" code completely, use "-nfssweight=ul=".

-extra=extra options
Pass extra options to the commands for otftotfm. To prevent extra options from
accidentily being interpreted as options to autoinst, they should be properly quoted.

-nofigurekern
Some fonts provide kerning pairs for tabular figures. This is very probably not what
you want (e.g., numbers in tables won't line up exactly). This option adds extra
--ligkern options to the commands for otftotfm to suppress such kerns. Note that this
option leads to very long commands (it adds one hundred --ligkern options), which may
cause problems on some systems; hence it is not active by default.

RECENT CHANGES

(See the source for the full story, all the way back to 2005.)

2021-11-15 Bugfix: font info parsing now works for Adobe Source Serif 4.

2021-07-21 Bugfixes:

- Yet another problem with argument quoting on Windows.

- Selecting numerator/denominator fonts didn't work as documented.

- Font info parsing failed for Microsoft Sitka and LucasFonts Thesis.

2021-04-01 The -encoding option now also accepts filenames of encoding files in
directories other than the current directory. Directory names containing
spaces do (or at least should) also work.

2020-12-18 Fixed a problem with files not being found on Windows. Added extra
"--unicoding" options to prevent getting lowercase f-ligatures in smallcaps
for some buggy fonts. Optimized font info parsing for DTL and TypeBy font
families. Cleaned up the code for better maintainability.

2020-07-29 Some changes in the generated sty and fd files, to improve compatibility with
the microtype package. Made sure that pfb fonts are always generated whenever
the input fonts are in otf format. Added the -t1suffix command-line option,
to modify the font and file names of those generated Type1 fonts.

2020-06-19 Added the "nomathgreek" option to generated style files. Reorganized the
generated style files to make them more standards-conforming.

2020-05-27 Added basic (and still somewhat experimental) math support. Implemented the
"scale=MatchLowercase" option value in the generated style files. "Wide"
fonts are mapped to the "sx" NFSS code instead of "x", to cater for League
Mono Variable's Wide and Extended widths. The generated style files now use
"\textsup" and "\textinf" instead of the more cryptic "\textsu" and "\textin"
to access superior and inferior characters (though the old forms are retained
for backwards compatibility).

2020-05-11 When present, use encoding files in the current working directory in
preference of the ones that come with autoinst. Changed the way ornament
fonts are created; ornament glyphs are now always included in the position
chosen by the font's designer.

2020-04-28 Fix a bug where the first font argument would be mistaken for an argument to
-inferiors.

2020-01-29 Don't create empty subdirectories in the target TEXMF tree.
