# OF816 Utilities

## index.rb

Usage: index.rb <file.s> \[coverage.yml]

This will index the words appearing in an assembly source file
and output YAML on STDOUT containing entries for each word along
with the help text derived from comments preceding the word.

Help text is derived from comments of the form:
```
; H: ( -- ) example help text
; H: a second line
```

A word can be excluded from indexing if the word noindex
is found on the line containing the dword or dwordq macro
for the word:
```
dword MY_WORD,"MY-WORD" ; noindex
```

Test coverage data (see platforms/GoSXB) can be merged into
the output in order to be used by the covrep.rb utility and
a future documentation generator.

## index2md.rb

Usage: index2md.rb index.yml

Convert index.yml to markdown on stdout for word documentation.

Efforts are made to add emphasis to stack effects and intelligently
split separate semantics.

## covrep.rb

Usage: covrep.rb index.yml

This takes the output (redirected to a file) from index.rb
and produces a test coverage report, listing the covered and
uncovered word counts, the words that are not covered, and the
percentage of words that are covered.

Example:

```
Total words: 402
Covered words: 292
Uncovered words: 110
