Return KEY’s value in the current TFM configuration.
Set KEY to VALUE in the current TFM configuration.
Return T if CHARACTER has an extension recipe.
Freeze FONT.
Freezing a font means that all dimensions normally expressed in design size
units are multiplied by it, so as to lead values in TeX point units.
If FONT is already frozen, this function does nothing and returns NIL.
Otherwise, it returns T.
Return FONT’s CODE character, or NIL.
Return kerning for CHARACTER1 and CHARACTER2, or NIL.
If CHARACTER1 and CHARACTER2 don’t belong to the same font, signal a
DIFFERENT-FONTS error.
Set KERNING for CHARACTER1 and CHARACTER2.
Return ligature for CHARACTER1 and CHARACTER2, or NIL.
If CHARACTER1 and CHARACTER2 don’t belong to the same font, signal a
DIFFERENT-FONTS error.
Set LIGATURE for CHARACTER1 and CHARACTER2.
Load FILE into a new font, and return it.
- If provided, DESIGN-SIZE overrides the font’s original value. It must be a
real greater or equal to 1.
- When FREEZE (NIL by default), freeze the font immediately after creation.
See the eponymous function for more information.
Only actual TFM data is currently supported. If OFM or JFM data is detected,
this function signals an EXTENDED-TFM warning and returns NIL.
While loading TFM data, any signalled condition is restartable with CANCEL-LOADING, in which case this function simply returns NIL.
Add NICKNAME (:TFM by default) to the :NET.DIDIERVERNA.TFM package.
Unfreeze FONT.
Unfreezing means performing the inverse of what FREEZE does.
If FONT is not frozen, this function does nothing and returns NIL. Otherwise,
it returns T.
Return the current version of TFM.
TYPE can be one of :number, :short or :long.
A version number is computed as major*10000 + minor*100 + patchlevel, leaving
two digits for each level. Alpha, beta and rc status are ignored in version
numbers.
A short version is something like 1.3{a,b,rc}4, or 1.3.4 for patchlevel.
Alpha, beta or rc levels start at 1. Patchlevels start at 0 but are ignored
in the output, so that 1.3.0 appears as just 1.3.
A long version is something like
1.3 {alpha,beta,release candidate,patchlevel} 4 "Artificial Uncial".
As for the short version, a patchlevel of 0 is ignored in the output.

Run a ligature/kerning program for CHARACTER.
The program starts at LIG/KERNS[INDEX] and uses the KERNS array. Running the
program eventually creates ligatures or kernings for CHARACTER and some other
character.
If an invalid index into LIG/KERNS is encountered, signal an
INVALID-TABLE-INDEX error. This error is immediately restartable with
ABORT-LIG/KERN-PROGRAM.
If an invalid ligature opcode is encountered, signal an
INVALID-LIGATURE-OPCODE error. This error is immediately restartable with
DISCARD-LIGATURE.
If an invalid index into KERNS is encountered, signal an INVALID-TABLE-INDEX
error. This error is immediately restartable with DISCARD-KERNING.
Finally, if an invalid character code is encountered, signal an INVALID-CHARACTER-CODE error. Depending on the context, this error is immediately restartable with DISCARD-LIGATURE or DISCARD-KERNING.
Apply LIGATURE to STATE and return the new state.
STATE is a list of characters, the first two being subject to LIGATURE.
Send SYMBOL’s INDENTation information to Emacs.
Emacs will set the ’common-lisp-indent-function property.
If INDENT is a symbol, use its indentation definition. Otherwise, INDENT is
considered as an indentation definition.
Return FONT’s CODE character.
If ERRORP (the default), check that the character exists, or signal an
INVALID-CHARACTER-CODE error. Note that a fake boundary character may be
retrieved by this function.

ITALIC-CORRECTION appropriately. The two remaining slots (NEXT-CHARACTER and
EXTENSION-RECIPE) will be initialized later if needed, when all character
metrics instances are created.

Make a new LIGATURE instance, and return it.
Parse the 8 character information tables from *STREAM* into FONT.
NC (EC - BC + 1), NW, NH, ND, NI, NL, NK, and NE are the declared lengths of
the 8 tables, that is, the char infos, widths, heights, depths, italic
corrections, lig/kern instructions, kerns, and extens respectively.
If a char info structure with a width index of 0 is not completely zero’ed
out, signal an INVALID-CHAR-INFO error. This error is immediately restartable
with SET-TO-ZERO.
If the first entry in the widths, heights, depths, or italic corrections table
is not 0, signal an INVALID-TABLE-START error. This error is immediately
restartable with SET-TO-ZERO.
If an index into the widths, heights, depths, or italic corrections tables is
invalid, signal an INVALID-TABLE-INDEX error. This error is immediately
restartable with SET-TO-ZERO.
If a lig/kern program is found for a boundary character, but there is no such
character in the font, signal a NO-BOUNDARY-CHARACTER error. This error is
immediately restartable with ABORT-LIG/KERN-PROGRAM.
If an index into the extens table is invalid, signal an INVALID-TABLE-INDEX error. This error is immediately restartable with DISCARD-EXTENSION-RECIPE.
If a cycle is found in a list of characters of ascending size, signal a
CHARACTER-LIST-CYCLE error. This error is immediately restartable with
DISCARD-NEXT-CHARACTER.
If a ligature is found to be cyclic, signal a LIGATURE-CYCLE error. This error
is immediately restartable with DISCARD-LIGATURE.
Finally, if an invalid character code is encountered, signal an INVALID-CHARACTER-CODE error. Depending on the context, this error is immediately restartable with DISCARD-NEXT-CHARACTER, or DISCARD-EXTENSION-RECIPE.
Parse a header of LENGTH words from *STREAM* into FONT.
If FONT’s design size is less than 1pt, signal an INVALID-DESIGN-SIZE error.
This error is immediately restartable with SET-TO-TEN.
However, if FONT’s design size was explicitly overridden, only signal an
INVALID-ORIGINAL-DESIGN-SIZE warning.
Read a fix word from *STREAM* and return it.
If LIMIT (the default), check that the number lies within ]-16,+16[, or
signal a FIX-WORD-OVERFLOW error. This error is immediately restartable with
SET-TO-ZERO.
Read a BCPL string out of PADDING bytes from *STREAM*.
The first byte in *STREAM* indicates the actual length of the string.
The remaining bytes are ignored.
If the declared string length is too large, signal an INVALID-STRING-LENGTH
error. This error is immediately restartable with READ-MAXIMUM-LENGTH or
DISCARD-STRING.
If the string is not in BCPL format (it contains parentheses or non plain ASCII characters, signal an INVALID-BCPL-STRING error. This error is immediately restartable with KEEP-STRING, FIX-STRING (replacing parentheses with slashes, and non plain ASCII characters with question marks), or DISCARD-STRING.
Read an unsigned 16 bits Big Endian integer from *STREAM* and return it. If >= 2^15, signal a U16-OVERFLOW error.
Read an unsigned 32 bits Big Endian integer from *STREAM*.
Like FORMAT, but if *STREAM* is bound, report that we’re reading from it.
Find the real start of a ligature/kerning program and run it.
See %run-ligature/kerning-program for more information.
If INDEX is invalid, signal an INVALID-TABLE-INDEX error. This error is immediately restartable with ABORT-LIG/KERN-PROGRAM.
Access NAMEd TABLE at INDEX.
If INDEX is out of bounds, signal an INVALID-TABLE-INDEX error.
Read a series of ~"string" to be concatenated together.
character-metrics)) ¶character-metrics)) ¶The character’s extension recipe, or NIL.
This slot is non-null only if this character is extensible (see TeX: the
Program [544]). It is mutually exclusive with the NEXT-CHARACTER slot, and
also with the existence of a ligature or kerning program for this character.
Parse a parameters section of LENGTH words from *STREAM* into FONT. Return remaining LENGTH.
Parse the 7 regular FONT parameters. Return remaining LENGTH.
math-symbols-font)) ¶Parse the 15 additional TeX math symbols FONT parameters.
math-extension-font)) ¶Parse the 6 additional TeX math extension FONT parameters.
Read remaining parameters into a parameters array.
Scale all FONT dimensions by FACTOR.
math-extension-font) factor) ¶Scaling method for MATH-EXTENSION-FONTs.
math-symbols-font) factor) ¶Scaling method for MATH-SYMBOL-FONTs.
Scaling method for regular FONTs.
The Anonymous Font usage error.
It signals an attempt at creating a font with no name.
The File Size Mixin condition.
It is used in both errors and warnings to report different declared and
actual file sizes.
The Invalid Original Design Size compliance warning.
It signals that, although overridden explicitly, an original design size was
too small (< 1pt).
The invalid original design size.
:value
The TFM table errors root condition.
This is the root condition for errors related to TFM tables.
The Char Info structure.
This structure is used to store decoded information from the char-info table
(see TeX: the Program [543]). Only one of LIG/KERN-INDEX, NEXT-CHAR, and
EXTEN-INDEX may be non-null at a time (see TeX: the Program [544]).
structure-object.
The Exten structure.
This structure is used to store decoded information from the exten table
(see TeX: the Program [546]).
The Lig/Kern structure.
This structure is used to store decoded information from the lig/kern table
(see TeX: the Program [545]).
The Extension Recipe class.
This class represents decoded information for extensible characters. Within
the context of this library, the expression "extension recipe" denotes an
instance of this class.
The recipe’s top character, or NIL.
:top-character
The recipe’s middle character, or NIL.
:middle-character
The recipe’s bottom character, or NIL.
:bottom-character
The recipe’s repeated character.
