Opus files
Opus files aggregate novella files. Opus files have the .opus suffix (like NoveLang Opus).
Command: insert
Opus files are useful when there is too much text to fit inside one Novella file. It is also easier to reorganize small Novellas by changing their order in a Opus file than copy-pasting inside one big file.
When Novella files become too numerous, Opus files can refer to multiple Novella files at once. Referring to project layout, here is a well-formed Opus file:
insert file:path/to/myfirstnovella.novella insert file:path/to/mysecondnovella.novella
When the Novellas are located in the same directory as the Opus file, the single dot notation (for current directory) is supported:
insert file:.
The recurse option scans novellas in subdirectories.
insert file:. recurse
The createlevel option adds the content of the file under one new level. The level title is the filename, path and .novella extension being trimmed.
The nohead option takes effect when using identifiers (explained later). When the identifier references a level, this options causes the level title to disappear. The nohead option is mutually exclusive with the createlevel option.
The sort option provides a sorting method when inserting several files.
insert file:. sort=path+
The sort option determines the ordering of Novellas when there are many. Currently supported values are:
path+for ascending sort on path name.path-for descending sort on file name.version+for ascending sort on version number.version-for descending sort on version number.
Version number if for files names of major.minor.fix.novella format, where major, minor and fix are positive numbers (this is Novelang’s format for version numbers by the way).
The levelabove option adds the content of the file(s) under the last previously created level.
insert file:some-novella.novella levelabove=2
The style=... assignment adds a STYLE node to each of the trees corresponding to added novella.
insert file:. style=mystyle
Expert users will find this is useful for customizing the output right from an XSLT stylesheet:
<!-- Process styled chapter: --> <xsl:apply-templates select="//n:chapter[n:style='mystyle']" /> <!-- Don't process styled chapter: --> <xsl:apply-templates select="//n:chapter[not(n:style!='')]" />
A sequence of composite identifiers (as defined in “Novella syntax” chapter) limits the insertion of reference Novella to some fragments.
insert file:my-novella \\Some-identifier \\Some-other
Command: mapstylesheet
The “mapstylesheet” command defines a stylesheet for one or more MIME type. Referring to project layout above, here is the command to insert in opus.opus file in order to render HTML documents with html-beautiful.xsl and PDF documents with pdf-beautiful.xsl.
mapstylesheets
html=html-beautiful.xsl
pdf=pdf-beautiful.xsl
