This is an application for looking up documentation in the words.tsv
|
|
data set.
|
|
|
|
It's intended to be used like:
|
|
|
|
./words.forth describe s:filter
|
|
|
|
Or:
|
|
|
|
./words.forth export glossary
|
|
|
|
First, exit if the required number of argumenta are not passed.
|
|
|
|
~~~
|
|
sys:argc #2 -eq? [ #0 unix:exit ] if
|
|
~~~
|
|
|
|
If we made it this far, at least two arguments were passed. This
|
|
assumes the first argument is the type of search and the second
|
|
is name of a word, class, or other detail to search for. Grab them
|
|
and save as `QUERY` and `TARGET`.
|
|
|

|
#0 sys:argv 'QUERY s:const
|
|
#1 sys:argv 'TARGET s:const

The *words.tsv* has the following fields:
|
|
|
|
| name | 0
|
|
| data stack | 1
|
|
| address stack | 2
|
|
| float stack | 3
|
|
| general description | 4
|
|
| interpret time description | 5
|
|
| compile time description | 6
|
|
| class handler | 7
|
|
| example 1 | 8
|
|
| example 2 | 9
|
|
| namespace | 10
|
|
| interface | 11
|
|
|
|
So 11 fields. These are stored, one line per entry, with the fields as
|
|
tab separated data.
