* Generalise parse-hexBALATON Zoltan2023-01-261-2/+34
| | | | | | | | | | | Add parse-nhex word reusing existing parse-ints and use that in parse-hex instead of an independent implementation. The parse-nhex name matches Apple OF, while SLOF calls the same operation hex-decode-unit so adding this word increases compatibility with other OF implementations.

* rstack.fs: add pseudo r-stack implementation for interpret modeMark Cave-Ayland2016-07-172-0/+22
| | | | | | | | The OS 9 boot loader uses the r-stack outside of a word in interpret mode. Provide an r-stack implementation which allows r-stack accesses in interpret mode using a separate pseudo stack. Signed-off-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk>

* Improve dir word by reducing complexity and adding some more diagnostics.Mark Cave-Ayland2012-11-241-21/+0
| | | | | | | | | | | Since the OF path resolution algorithm automatically passes anything following a ':' as an argument to the specified device, we don't need to bother with handling this ourselves. As a side effect, the auxiliary word split-path-device is no longer needed as we can isolate the path by doing a simple split on ','.

* Implementation of Forth local variables for OpenBIOS.Mark Cave-Ayland2012-11-232-0/+198
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some bootloaders, particularly OS X, execute Forth strings that make use of Forth local variables. This patch provides an implementation that allows OpenBIOS to execute such code. A couple of examples are included below: : diff.squares { A B -- A*A-B*B } A A * B B * - ; : myword { ; cat dog } 4 -> cat 5 -> dog cat \ cat's value pushed onto stack ( - cat) dog \ dog's value pushed onto stack (cat - cat dog ) + cr ." Total animals = " . cr ; Since the Forth locals stack and temporary dictionary take up extra space, the locals implementation is protected by a new CONFIG_LOCALS build variable.

* forth: Fix ([IF]) to handle nested [IFDEF] as wellAndreas Färber2010-12-051-0/+1
| | | | | | | | | | | | | | | | | Depending on the condition, either the [IFDEF] FOO or the [ELSE] would get compiled as an [IF], eating words until [ELSE] or [THEN] respectively. While doing so, [IFDEF] does not get compiled to [IF], so we need to handle nested [IFDEF] to account for its [ELSE] or [THEN]. This fixes [IFDEF] not disabling the full section of code. Thanks to Segher for pointing me in the right direction.
