## Syntax
|
|
|
|
|
|
|
|
|
|
**Basic**
|
|
|
|
|
|
|
|
|
|
```bf
|
|
|
|
|
,. IO
|
|
|
|
|
<> Address manipulation
|
|
|
|
|
+- Value manipulation
|
|
|
|
|
[] Looping construct
|
|
|
|
|
```
|
|
|
|
|
**Comments**
|
|
|
|
|
|
|
|
|
|
`//` - Single Line
|
|
|
|
|
|
|
|
|
|
`/* */` - Multi Line
|
|
|
|
|
|
|
|
|
|
**Repeats**
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
<symbol><number>
|
|
|
|
|
(<symbols>)<number>
|
|
|
|
|
```
|
|
|
|
|
Eg.
|
|
|
|
|
```
|
|
|
|
|
+65. //prints A
|
|
|
|
|
>

|
|
|
|
(+65>)3 //stores AAA
|
|
|
|
|
(<.)3 //prints AAA

|
|
|
## Setup oddities (dev)
|
|
|
|
|
|
|
|
|
|
1. Copy antlr4's cpp libs to `./libs/antlr4`. (Please take care that the include folder points straight to the files not to `antlr-runtime`)
|
|
|
|
|
2. Copy `antlr-4.8-complete.jar` to `./thirdparty/antlr`.
|
|
|
|
|
3. Generate parsers to `./libs/generated` or use VSCode with the ANTLR extension.
