The name of this release.
The general naming theme for TFM is "Uncial Fonts", from the LaTeX Font
Catalogue (https://www.tug.org/FontCatalogue/uncialfonts.html).
The status of this release.
The status level of this release.
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.

The stream being read.
Wrapper around ‘clindent’ to avoid quoting SYMBOL and INDENT.
Define a context-aware report function for a CONDITION of TYPE.
The reporting is ultimately done by calling FORMAT on FORMAT-STRING with
ARGUMENTS.
Like DEFCONSTANT, but reuse existing value if any.
Map BODY on OBJECT ACCESSORS, each in turn available as VAR.
Map BODY on CHARACTER metrics dimension accessors available as VAR.
Map BODY on FONT dimension accessors available as VAR.
Map BODY on math extension FONT dimension accessors available as VAR.
Map BODY on FONT dimension accessors available as VAR.
Call TABLE-AREF, computing the table name from TABLE.
Execute BODY within a particular condition signalling context.
While BODY is executing, conditions of type CONDITION-TYPE (not evaluated) are
caught and augmented with an instance of CONTEXT-TYPE (not evaluated)
initialized with INITARGS.
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.
Make FONT’s CHARACTER accessible by its code.
Like FORMAT, but *STREAM* and CONTEXT-aware.
- When *STREAM*, report that we’re reading from it to STREAM.
- When CONTEXT, report the context string to STREAM.
- Finally, print FORMAT-STRING with ARGUMENTS to STREAM.

If *STREAM* is longer than expected, signal a FILE-OVERFLOW warning.
If the declared header length is less than 2, signal an INVALID-HEADER-LENGTH
error.

If the widths, heights, depths, italic corrections, or extens tables lengths
are not within the expected range, signal an INVALID-TABLE-LENGTH error.
Finally, if the declared sections lengths don’t add up to the declared file length, signal an INVALID-SECTION-LENGTHS error.
Make a new CHARACTER-METRICS instance, and return it.
Initialize the character’s CODE, FONT, WIDTH, HEIGHT, DEPTH, and
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 EXTENSION-RECIPE with REPEATED-CHARACTER and return it. The recipe may also have a TOP-, MIDDLE-, and BOTTOM-CHARACTER.
Make a new NAMEd FONT instance, and return it.
If INITARGS are provided, pass them as-is to MAKE-INSTANCE.
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 numbers of
entries in 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 one char-info from *STREAM* into a new CHAR-INFO instance.
If the char-info denotes a non-existent character (that is, it is has a width
index of 0) but is not completely blank, signal a SPURIOUS-CHAR-INFO warning.
Read one exten from *STREAM* into a new EXTEN instance.
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 one lig/kern from *stream* into a new LIG/KERN instance.
Read a padded string out of PAD bytes from *STREAM*.
The first byte in *STREAM* indicates the actual length of the string.
If the declared string’s length is too large, signal an
INVALID-PADDED-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-ASCII
characters, signal an INVALID-PADDED-STRING error. This error is immediately
restartable with KEEP-STRING, FIX-STRING (replacing parentheses with slashes,
and non-ASCII characters with question marks), or DISCARD-STRING.
If the string is not padded with zeros, signal a PADDED-STRING-OVERFLOW warning.
Read an unsigned 16 bits Big Endian integer from *STREAM* and return it. If >= 2^15, signal a U16-OVERFLOW error.
