Context

Get a context

cid       string // rid.cid or just cid
name      string // a unique name in cid
params    paramsparser.Params
redis     &redisclient.Redis
dbcollection &dbfs.DBCollection  

• cid is the unique id for a circle.
• the default context is "default"
• each context can have params attached to it, as can be set by the heroscripts
• each context has a redis client (can be a different per context but normally not)
• context db is a fs db (key value stor)

import freeflowuniverse.herolib.core.base


struct ContextGetArgs {
	name        string = "default" // a unique name in cid
	interactive bool = true
}

//get context based on name, can overrule interactivity
play.context_get(args_ ContextGetArgs) !Context

Work with a context

E.g. gitstructure is linked to a context

//return the gistructure as is being used in context
fn (mut self Context) gitstructure() !&gittools.GitStructure 

//reload gitstructure from filesystem
fn (mut self Context) gitstructure_reload()

//return the coderoot as is used in context
fn (mut self Context) coderoot() !string 

// load the context params from redis
fn (mut self Context) load() !

// save the params to redis
fn (mut self Context) save() !

get a custom DB from context

//get a unique db with a name per context
fn (mut self Context) db_get(dbname string) !dbfs.DB 

//get configuration DB is always per context
fn (mut self Context) db_config_get() !dbfs.DB

configure context through heroscript

!!context.configure
    name:'test'
    coderoot:''
    interactive:true

Configure a context

A context can get certain configuration e.g. params, coderoot, ... (in future encryption), configuration is optional.

// configure a context object
// params:
// ```
// cid          string = "000" // rid.cid or cid allone
// name         string // a unique name in cid
// params       string
// coderoot	 string
// interactive  bool
// ```
