7 Weave

If the scanner, parser, and analyser have successfully (i.e. with no errors, severe errors, or fatal errors) completed, and either or both of the two Weave options (+T, U) is turned on (both are off  by default), then the Weave component of FunnelWeb is invoked to generate one or two documentation files.

Target Typesetter

All versions of FunnelWeb up to V3.1 could generate only TeX documentation. This used the +t option. FunnelWeb V3.2 can now generate HTML documention using the +u option. You can generate both at once if you like.

Cross Reference Numbering

When FunnelWeb produces its typeset documentation, it numbers  each section and each macro definition and cross references the macro definitions. The exact scheme used has been carefully thought out. However, as it can be a little confusing to the beginner, it is explained here in full.

The most important thing is that there is no relation  between the macro numbering and the section numbering. In Knuth's Web there are only section numbers. In FunnelWeb, the numbering of sections and macros is separated.

In FunnelWeb, sections  are numbered hierarchically in ascending order. For example, the second level-C section of the third level-B section of the first level-A section is numbered "1.3.2". In contrast, macro definitions  are numbered sequentially in ascending order. For example, the first macro definition is number 1, the second is number 2, and so on. Note that it is macro definitions  that are numbered, not macros . This distinction is necessary because additive macros (i.e. the ones with +=) can be defined by a collection of partial definitions scattered throughout the input file. A single additive macro may be defined in definitions 5, 67, 128, and 153.
