General Purpose PostScript Generating Utility

3.2.3 Available Escapes

Supported escapes are:

`\\'

character `\'

`\%'

character `%'

`\$'

character `$'

`\#'

character `#'

`#?cond|if_true|if_false|'

this may be used for conditional assignment. The separator (presented here as `|') may be any character. if_true and if_false may be defined exactly the same way as regular headers, included escapes and the `#?' construct.

The available tests are:

`#?1'

`#?2'

`#?3'

true if tag 1, 2 or 3 is not empty. See item `$t1' for explanation.

`#?d'

true if Duplex printing is requested (`-s2').

`#?j'

true if bordering is asked (`-j').

`#?l'

true if printing in landscape mode.

`#?o'

true if only one virtual page per page (i.e., `#v' is 1).

`#?p'

a page range has been specified (i.e., `#p' is not empty).

`#?q'

true if a2ps is in quiet mode.

`#?r'

true if major is rows (`--major=rows').

`#?v'

true if printing on the back side of the sheet (verso).

`#?V'

true if verbosity level includes the `tools' flag (See section 3.1.2 Global Options. option `--verbosity').

`#!key|in|between|'

Used for enumerations. The separator (presented here as `|') may be any character. in and between are escapes.

The enumerations may be:

`#!$'

enumeration of the command line options. In this case in in never used, but is replaced by the arguments.

`#!f'

enumeration of the input files in the other they were given.

`#!F'

enumeration of the input files in the alphabetical order of their names.

`#!s'

enumeration of the files appearing in the current sheet.

For instance, the escapes `The files printed were: #!f|$n|, |.' evaluated with input `a2ps NEWS main.c -o foo.ps', gives `The files printed were: NEWS, main.c.'.

As an exception, `#!' escapes use the width as the maximum number of objects to enumerate if it is positive, e.g., `#10!f|$n|, |' lists only the ten first file names. If width is negative, then it does not enumerate the -width last objects (e.g., `#-1!f|$n|, |' lists all the files but the last).

`${var}'

value of the environment variable var if defined, nothing otherwise.

`${var:-word}'

if the environment variable var is defined, then its value, otherwise word.

`${var:+word}'

if the environment variable var is defined, then word, otherwise nothing.

`$[num]'

value of the numth argument given on the command line. Note that $[0] is the name under which a2ps has been called.

`#{key}'

expansion of the value of the variable key if defined, nothing otherwise (see section 4.9 Your Variables)

`#{key:-word}'

if the variable var is defined, then the expansion of its, otherwise word.

`#{key:+word}'

if the variable var is defined, then word, otherwise nothing.

`#.'

the extension corresponding to the current output language (e.g. `ps').

`%*'

current time in 24-hour format with seconds `hh:mm:ss'

`$*'

file modification time in 24-hour format with seconds `hh:mm:ss'

`$#'

the sequence number of the current input file

`%#'

the total number of files

`%a'

the localized equivalent for `Printed by User Name'. User Name is obtained from the variable `user.name' (see section 4.9.2 Predefined Variables).

`%A'

the localized equivalent for `Printed by User Name from Host Name'. The variables `user.name' and `user.host' are used (see section 4.9.2 Predefined Variables).

`%c'

trailing component of the current working directory

`%C'

current time in `hh:mm:ss' format

`$C'

file modification time in `hh:mm:ss' format

`%d'

current working directory

`$d'

directory part of the current file (`.' if the directory part is empty).

`%D'

current date in `yy-mm-dd' format

`$D'

file modification date in `yy-mm-dd' format

`%D{string}'

format current date according to string with the strftime(3) function.

`$D{string}'

format file's last modification date according to string with the strftime(3) function.

`%e'

current date in localized short format (e.g., `Jul 4, 76' in English, or `14 Juil 89' in French).

`$e'

file modification date in localized short format.

`%E'

current date in localized long format (e.g., `July 4, 76' in English, or `Samedi 14 Juillet 89' in French).

`$E'

file modification date in localized long format.

`$f'

full file name (with directory and suffix).

`\f'

character `\f' (form feed).

`#f0'

`#f9'

ten temporary file names. You can do anything you want with them, a2ps removes them at the end of the job. It is useful for the delegations (see section 4.10 Your Delegations) and for the printer commands (see section 4.5 Your Printers).

`%F'

current date in `dd.mm.yyyy' format.

`$F'

file modification date in `dd.mm.yyyy' format.

`#h'

medium height in PostScript points

`$l^'

top most line number of the current page

`$l.'

current line number. To print the page number and the line interval in the right title, use `--right-title="$q:$l^-$l."'.

`$l#'

number of lines in the current file.

`%m'

the host name up to the first `.' character

`%M'

the full host name

`\n'

the character `\n' (new line).

`%n'

shortcut for the value of the variable `user.login' (see section 4.9.2 Predefined Variables).

`$n'

input file name without the directory part.

`%N'

shortcut for the value of the variable `user.name' (see section 4.9.2 Predefined Variables).

`$N'

input file name without the directory, and without its suffix (e.g., on `foo.c', it will produce `foo').

`#o'

name of the output, before substitution (i.e., argument of `-P', or of `-o').

`#O'

name of the output, after substitution. If output goes to a file, then the name of the file. If the output is a symbolic printer (see section 4.5 Your Printers), the result of the evaluation. For instance, if the symbolic printer `file' is defined as `> $n.%.', then `#O' returns `foo.c.ps' when printing `foo.c' to PostScript. `#o' would have returned `file'.

`#p'

the range of the page to print from this page. For instance if the user asked `--pages=1-10,15', and the current page is 8, then `#p' evaluates to `1-3,8'.

`$p^'

number of the first page of this file appearing on the current sheet. Note that `$p.', evaluated at the end of sheet, is also the number of the last page of this file appearing on this sheet.

`$p-'
