YAMAS stand for Yet Another Markup As Script
I use lots of YAML in different apps. They all have their own implicit logic behind data structure and documentation. Nowadays, YAML is being used as near-script language anyways. (Also it looks like Python.)
- Super simple
- No native loops
- Limited native functions:
- ECHO@
- LINE@
- HTTP@
- BASH@
- PARSE@
Use Rust's "ownership" concept.
- A variable ownership can be passed around using @TAKE and @PUT.
- Only @RUN can be the owner (should we change the name @RUN to @THREAD to make it more clear? 🤔)
- Once @RUN is run, values in variables are dropped and cleaned
THREAD@:
- ECHO@: "Hello World \n"
- LINE@: "Hello World"RUN@:
- SET@:
- NAME@: hello
VALUE@: "world"
- SET@
- NAME@: peace
- VALUE@: true
- IF@:
AND@:
- EQ@:
- ${hello}
- "world"
- EQ@:
- ${peace}
- true
THEN@:
- ECHO@: |
Hello World! RUN@:
- SET@:
- NAME@: hello
VALUE@: world
- IF@:
- EQ@:
- ${hello}
- "world"
THEN@:
- GOTO@: 1
- GOTO@: 2
- GOTO@: 3
- LOC_1@:
- ECHO@: Hello
- RETURN@
- LOC_2@:
- ECHO@: " World"
- RETURN@
- LOC_3@:
- ECHO@: "\n"
- RETURN@
RUN@:
- FN@: World
TAKE@:
- greeting
RUN@:
- IF@: ${greeting} == "world"
THEN@:
- RETURN: "World"
- ECHO@:
FROM@:
- "Hello"
- FROM_CALL@: World
PUT@:
- greeting: "Hello"- FROM@
RUN@:
- ECHO@:
FROM@:
- "Hello"
- " World"
- "\n"

"soo": "taa",
"bip": {

SET_FROM@:

ECHO@: ${bipbap}
- EQ@, NE@, GT@, L@, GTE@, LTE@

- "bar" foo === "bar"- ADD@, SUB@, MUL@, DIV@
@SET_NUM:
