# rl'
|
|
|
|
`rlp` (ruelang') will be a lazily-evaluated purely-functional language heavily
|
|
imitating Haskell.
|
|
|
|
### Architecture
|
|
|
|
|
|
|
|
### Build Info
|
|
* rlp is built using [Cabal](https://www.haskell.org/ghcup/)
|
|
* rlp's documentation is built using [Sphinx](https://www.sphinx-doc.org/en/master/)
|
|
|
|
```sh
|
|
$ cabal build # Build the rlpc compiler
|
|
$ cabal install # Install rlpc to $PATH
|
|
$ cabal haddock # Build the API docs w/ Haddock
|
|
$ make -C doc html # Build the primary docs w/ Sphinx
|
|
|
|
# run the test suite
|
|
$ cabal test --test-show-details=direct
|
|
```
|
|
|
|
### Use
|
|
|
|
#### TLDR
|
|
|
|
```sh
|
|
# Compile and evaluate examples/rlp/QuickSort.rl
|
|
$ rlpc examples/QuickSort.rl
|
|
# Compile and evaluate t.cr, with evaluation info dumped to t.log
|
|
$ rlpc -ddump-eval -l t.log t.cr
|
|
# Compile and evaluate t.rl, dumping the desugared Core
|
|
$ rlpc -ddump-desugared t.rl
|
|
# Compile and evaluate t.rl with all compiler messages enabled
|
|
$ rlpc -dALL t.rl
|
|
```
|
|
|
|
#### Options
|
|
|
|
```sh
|
|
Usage: rlpc [-l|--log FILE] [-d DEBUG FLAG] [-f COMPILATION FLAG]
|
|
[-e|--evaluator gm|ti] [--heap-trigger INT] [-x|--language rlp|core]
|
|
FILES...
|
|
```
|
|
|
|
Available debug flags include:
|
|
* `-ddump-desugared`: dump Core generated from rl'
|
|
* `-ddump-parsed-core`: dump raw Core AST
|
|
* `-ddump-parsed`: dump raw rl' AST
|
|
* `-ddump-eval`: dump evaluation logs
|
|
* `-dALL`: disable debug message filtering. enables **all** debug messages
|
|
|
|

|
|
|
|
### Milestones
|
|
(This list is incomplete.)
|
|
|
|
Items are marked off not as they are 100% implemented, but rather once I
|
|
consider them stable enough that completion is soley a matter of getting
|
|
around to it -- no tough design decisions, theorising, etc. remain. For
|
|
example, as of writing this, the rl' frontend parser is not fully featured,
|
|
yet it is marked off on this list; finishing it would require cranking out
|
|
the remaining grammatical rules, and no work on complex tasks like layout
|
|
parsing remains.

|
|
- [ ] Core polish
|
|
- [ ] Better, stable parser
|
|
- [ ] Better, stable lexer
