NAME

tbl - format tables for troff

SYNOPSIS

ttbbll [ -CCvv ] [ files... ]

DESCRIPTION

This manual page describes the GNU version of ttbbll, which is part of the groff document formatting system. ttbbll compiles descriptions of tables embedded within ttrrooffff input files into commands that are understood by

ttrrooffff. Normally, it should be invoked using the -tt option of ggrrooffff..

It is highly compatible with Unix ttbbll. The output generated by GNU ttbbll cannot be processed with Unix ttrrooffff; it must be processed with GNU ttrrooffff. If no files are given on the command line, the standard input

will be read. A filename of - will cause the standard input to be

read. OOPPTTIIOONNSS

-CC Recognize ..TTSS and ..TTEE even when followed by a character other

than space or newline.

-vv Print the version number.

UUSSAAGGEE ttbbll expects to find table descriptions wrapped in the ..TTSS (table start) and ..TTEE (table end) macros. The line immediately following the ..TTSS macro may contain any of the following global options (ignoring the

case of characters - Unix tbl only accepts options with all characters

lowercase or all characters uppercase):

cceenntteerr Centers the table (default is left-justified). The alternative

keyword name cceennttrree is also recognized (this is a GNU tbl exten-

sion). ddeelliimm((xy)) Use x and y as start and end delimiters for eeqqnn(1). eexxppaanndd Makes the table as wide as the current line length. bbooxx Encloses the table in a box. ddoouubblleebbooxx Encloses the table in a double box. aallllbbooxx Encloses each item of the table in a box.

ffrraammee Same as box (GNU tbl only).

ddoouubblleeffrraammee

Same as doublebox (GNU tbl only).

ttaabb((x)) Uses the character x instead of a tab to separate items in a line of input data. lliinneessiizzee((n))

Sets lines or rules (e.g. from bbooxx) in n-point type.

nnookkeeeepp Don't use diversions to prevent page breaks (GNU tbl only).

Normally ttbbll attempts to prevent undesirable breaks in the table by using diversions. This can sometimes interact badly with

macro packages' own use of diversions, when footnotes, for exam-

ple, are used. ddeecciimmaallppooiinntt((c)) Set the character to be recognized as the decimal point in

numeric columns (GNU tbl only).

nnoossppaacceess

Ignore leading and trailing spaces in data items (GNU tbl only).

The global options must end with a semicolon. There might be white-

space after an option and its argument in parentheses. After global options come lines describing the format of each line of the table. Each such format line describes one line of the table itself, except that the last format line (which you must end with a

period) describes all remaining lines of the table. A single key char-

acter describes each column of each line of the table. You may run format specs for multiple lines together on the same line by separating them with commas. You may follow each key character with specifiers that determine the font and point size of the corresponding item, that determine column

width, inter-column spacing, etc.

The longest format line defines the number of columns in the table; missing format descriptors at the end of format lines are assumed to be `L'. Extra columns in the data (which have no corresponding format entry) are ignored. The available key characters are: c,C Centers item within the column.

r,R Right-justifies item within the column.

l,L Left-justifies item within the column.

n,N Numerically justifies item in the column: Units positions of numbers are aligned vertically. s,S Spans previous item on the left into this column.

a,A Centers longest line in this column and then left-justifies all

other lines in this column with respect to that centered line. ^ Spans down entry from previous row in this column.

,- Replaces this entry with a horizontal line.

= Replaces this entry with a double horizontal line. | The corresponding column becomes a vertical rule (if two of these are adjacent, a double vertical rule).

A vertical bar to the left of the first key-letter or to the right of

the last one produces a line at the edge of the table.

Here are the specifiers that can appear in suffixes to column key let-

ters: b,B Short form of fB (make affected entries bold). i,I Short form of fI (make affected entries italic). t,T Start an item vertically spanning rows at the top of its range rather than vertically centering it. d,D Start an item vertically spanning rows at the bottom of its

range rather than vertically centering it (GNU tbl only).

v,V Followed by a number, this indicates the vertical line spacing

to be used in a multi-line table entry. If signed, the current

vertical line spacing is incremented or decremented (using a

signed number instead of a signed digit is a GNU tbl extension).

A vertical line spacing specifier followed by a column separa-

tion number must be separated by one or more blanks. No effect if the corresponding table entry isn't a text block. f,F Either of these specifiers may be followed by a font name (either one or two characters long), font number (a single

digit), or long name in parentheses (the last form is a GNU tbl

extension). A one-letter font name must be separated by one or

more blanks from whatever follows. p,P Followed by a number, this does a point size change for the

affected fields. If signed, the current point size is incre-

mented or decremented (using a signed number instead of a signed

digit is a GNU tbl extension). A point size specifier followed

by a column separation number must be separated by one or more blanks. w,W Minimal column width value. Must be followed either by a ttrrooffff(1) width expression in parentheses or a unitless integer. If no unit is given, en units are used. Also used as the default line length for included text blocks. If used multiple times to specify the width for a particular column, the last entry takes effect.

x,X This is a GNU tbl extension. Either of these specifiers may be

followed by a macro name (either one or two characters long), or

long name in parentheses. A one-letter macro name must be sepa-

rated by one or more blanks from whatever follows. The macro which name can be specified here must be defined before creating the table. It is called just before the table's cell text is output. As implemented currently, this macro is only called if block input is used, that is, text between `T{' and `T}'. The macro should contain only simple ttrrooffff requests to change the text block formatting, like text adjustment, hyphenation, size, or font. The macro is called after other cell modifications like bb, ff or vv are output. Thus the macro can overwrite other modification specifiers.

e,E Make equally-spaced columns.

u,U Move the corresponding column up one half-line.

z,Z Ignore the corresponding column for width-calculation purposes.

A number suffix on a key character is interpreted as a column separa-

tion in ens (multiplied in proportion if the eexxppaanndd option is on). Default separation is 3n. The format lines are followed by lines containing the actual data for the table, followed finally by ..TTEE. Within such data lines, items are normally separated by tab characters (or the character specified with the ttaabb option). Long input lines can be broken across multiple lines

if the last character on the line is `\' (which vanishes after concate-

nation). A dot starting a line, followed by anything but a digit is handled as a troff command, passed through without changes. The table position is unchanged in this case. If a data line consists of only `' or `=', a single or double line, respectively, is drawn across the table at that point; if a single item in a data line consists of only `' or `=', then that item is replaced by a single or double line, joining its neighbours. If a data item consists only of `\' or `\=', a single or double line, respectively,

is drawn across the field at that point which does not join its neigh-

bours. A data item consisting only of `\Rx' (`x' any character) is replaced by repetitions of character `x' as wide as the column (not joining its neighbours).

A data item consisting only of `\^' indicates that the field immedi-

ately above spans downward over this row. A text block can be used to enter data as a single entry which would be too long as a simple string between tabs. It is started with `T{' and closed with `T}'. The former must end a line, and the latter must start a line, probably followed by other data columns (separated with tabs). By default, the text block is formatted with the settings which were active before entering the table, possibly overridden by the vv and

ww tbl specifiers. For example, to make all text blocks ragged-right,

insert ..nnaa right before the starting ..TTSS (and ..aadd after the table). To change the data format within a table, use the ..TT&& command (at the start of a line). It is followed by format and data lines (but no global options) similar to the ..TTSS request. IINNTTEERRAACCTTIIOONN WWIITTHH EEQQNN ttbbll(1) should always be called before eeqqnn(1) (ggrrooffff(1) automatically takes care of the correct order of preprocessors). GGNNUU TTBBLL EENNHHAANNCCEEMMEENNTTSS There is no limit on the number of columns in a table, nor any limit on the number of text blocks. All the lines of a table are considered in deciding column widths, not just the first 200. Table continuation (..TT&&) lines are not restricted to the first 200 lines. Numeric and alphabetic items may appear in the same column. Numeric and alphabetic items may span horizontally. ttbbll uses register, string, macro and diversion names beginning with the digit 33. When using ttbbll you should avoid using any names beginning with a 33.

BUGS

You should use ..TTSS HH/..TTHH in conjunction with a supporting macro package

for all multi-page boxed tables. If there is no header that you wish

to appear at the top of each page of the table, place the ..TTHH line

immediately after the format section. Do not enclose a multi-page ta-

ble within keep/release macros, or divert it in any other way. A text block within a table must be able to fit on one page.

The bbpp request cannot be used to force a page-break in a multi-page ta-

ble. Instead, define BBPP as follows ..ddee BBPP

..iiee ''\\\\nn((..zz'''' ..bbpp \\\\$$11

..eell \\!!..BBPP \\\\$$11

.... and use BBPP instead of bbpp. Using \a directly in a table to get leaders will not work. This is correct behaviour: \a is an uunniinntteerrpprreetteedd leader. To get leaders use a real leader, either by using a control A or like this: ..ddss aa \\aa ..TTSS ttaabb((;;));; llww((11ii)) ll.. AA\\**aa;;BB ..TTEE RREEFFEERREENNCCEE
