- NAME
- RISCOS::Text::PrettyPrint -- perl module that emulates
- OS_PrettyPrint
-
- SYNOPSIS
- use RISCOS::Text::PrettyPrint;
- $expand = prettyprint_expand ($sometext, $special);
-
- @kernel_dict = read_riscosdict ('Resources:$.Resources.Kernel.Dictionary');
- $expand = prettyprint_expand ($sometext, '', @kernel_dict);
-
-
- DESCRIPTION
- RISC OS provides a call `OS_PrettyPrint' that both formats text
- in a *pretty* fashion and allows a limited form of text
- compaction by using a dictionary. `prettyprint_expand' does not
- perform the line wrapping or tab expansion of `OS_PrettyPrint'
- (see the Text::Wrap manpage and the Text::Tabs manpage if this
- is needed) but does perform the dictionary expansion and
- converts the `OS_PrettyPrint' codes for non-breaking space and
- newline (`<31>' and `<13>' respectively) to `<160>' and `<10>'
- (a newline).
-
- The second (optional) parameter to `prettyprint_expand' is a
- *special string* which is used as dictionary entry zero. The
- remaining parameters are form the dictionary. If no dictionary
- is supplied then the default RISC OS dictionary is used (as in
- `OS_PrettyPrint'), which contains text common to the syntax
- messages of many modules.
-
- `read_riscosdict' reads the `OS_PrettyPrint' dictionary format
- and converts it to an array. If passed a string this will be
- taken as a filename and opened. If passed a reference to a
- filehandle this will be read from. (This allows reading of the
- default dictionary from the `DATA' filehadle of this module.
-
- EXAMPLE
- This will print out the default dictionary.
-
- use RISCOS::Text::PrettyPrint ':DEFAULT', '@default_dict';
-
- foreach $entry (0 .. $#default_dict)
- {
- print prettyprint_expand (sprintf ("%2d: \c[%c\n", $entry, $entry),
- '<Special string>');
- }
