LAVA MARKUP GENRATION TOOL

Lava is a markup generation tool built for obsidian Version: 0.0.5 creator: Joshua Davis

STILL IN VERY EARLY DEVELOPMENT NOT RECOMMENDED FOR PERSONAL USE

open lava-about in obisidian for developer information on the development of LAVA

npm i lava-md -g

Inline Lava

all inline lava starts with %%| and ends with |%%.

form: %%| params call -> lifecycle |%%

params

a inline json object to be passed into to call function

ex: {
    "hello": "world"
}

call

a call is a name of a template that will be injected under the inline lava

lifecycle

the lifecycle of a inline lava tells the parser weather to ignore, delete, or update the data.

implemented now are...

pre-render (will be rendered once and turn into a rendered tag. same as if left blank) rendered (will never be updated. Data already rendered) auto (data will be updated whenever the file is saved and lava run is called again)

ex: %%| {"hello", "world"} make_title -> auto |%%

Lava Templates

templates use the extension .lava templates will be copied under inline lava tags and end with a %%| end |%% tag.

lava template data use a different starting and ending tags for injecting data of "%%!" and "!%%"

Basic parameters

to inject paramaters into inline lava use the params json object

// passed into inline call

{
    "cool": {
        "hello": "world"
    },
    "apples": ["Red", "Green", "Fuji"],
    "people": ["Josh", "John", "Alice"]

}

// inside a .lava template ex: %%! params.cool.hello !%%

Objects

Inline calls allow you to concatenate objects to your input objects

// passed into inline call

{
    ...(apples.json), 
    "people": ["Josh", "John", "Alice"],
    "name": "John"
}

concatinating objects happens at runtime and updates everytime the object is run. This allows persistent data to be used in mutiple template calls.

Looping

// loop over arrays

%%!FOR apple in params.apples {
    I like %%! apple !%% apples!
}!%%

output: I like Red apples! I like Green apples! I like Fuji apples!

//nested for loops

%%!FOR apple in params.apples {
    %%!FOR person in params.people {
        %%! person !%% like's %%! apple !%% apples!
    }!%%
}!%%

Conditionals

Currently the only conditionals supported in templates are simple IF statements

%%!IF apple == "Red" {
    APPLE IS RED!
}!%%

Scripts

Not Implemented Yet Scripts ONLY run when run by lava script or in lava-watch interface. They do NOT run when the template is called.

%%# o/apples.json
    PUSH apples.types "round" 
    ADD job "Apple picker"
    ADD favorite %%!apple!%%
    RUN create-apple-tree 
#%%
%%# n/cs170/%%!apple!%%
    RUN create-apple-tree apples.json
#%%

Comments

%%@ hello this is a comment in a .lava file @%%
