pseudo 
Pseudo aims to be a 'pseudo' language. Its primary purpose is simplify and unitize development operations.
Language
Types
The following core types are supported:
- number
- float
- string
- list
- map
Functions
There are a few builtin functions with the ability to register custom functions. A complete set of functions can be found in the functions.go file.
Syntax
A code block is any data wrapped in ${...}. This may be a variable, function
or any other supported operation
Escape sequence
A code block within ${...} can be escaped by prepending a $ to it like so
$${...}
Development
Test
make test
Build
make pseudo
Run
./pseudo -h

Functions ¶
func LoadVariableBytes ¶
LoadVariableBytes loads an index from the given bytes.
func LoadVariables ¶
LoadVariables loads an index from the URL. It reads the data, parses and indexes the data structure
Types ¶
type IndexOptions ¶
type IndexOptions struct {
// Content type of context data
ContentType string
}
IndexOptions are index loader options
type Script ¶
type Script struct {
// contains filtered or unexported fields
}
Script is an evaluatable script
func NewScriptBytes ¶
NewScriptBytes this simply removes the shabang line if one is specified
type VM ¶
type VM struct {
// contains filtered or unexported fields
}
VM is used to parse and eval a given script
func (*VM) Eval ¶
func (vm *VM) Eval() (*hil.EvaluationResult, error)
Eval evaluates a parsed script. Parse must be called before a call to Eval can be made
func (*VM) ParseEval ¶
func (vm *VM) ParseEval(script string, vars scope.Variables) (result *hil.EvaluationResult, err error)
ParseEval is a helper function to set variables, parse the script and evaluate it
func (*VM) RegisterFunc ¶
RegisterFunc registers a function to the vm
