Parse placeholder and wildcard text commands

Last update: Nov 24, 2022

Overview

allot

allot is a small Golang library to match and parse commands with pre-defined strings. For example use allot to define a list of commands your CLI application or Slackbot supports and check if incoming requests are matching your commands.

The allot library supports placeholders and regular expressions for parameter matching and parsing.

Usage

cmd := allot.NewCommand("revert <commits:integer> commits on <project:string> at (stage|prod)")
match, err := cmd.Match("revert 12 commits on example at prod")

if (err != nil)
  commits, _ = match.Integer("commits")
  project, _ = match.String("project")
  env, _ = match.Match(2)

  fmt.Printf("Revert \"%d\" on \"%s\" at \"%s\"", commits, project, env)
} else {
  fmt.Println("Request did not match command.")
}

Examples

See the hanu Slackbot framework for a usecase for allot:

feat: option for regex escaping

This PR adds new constructor for Command called NewWithEscaping that escapes the Command pattern for regex characters [],(),... which allows then passing commands with these characters. I have opted for a new constructor in order not to break the current API and also leave an option for actually accepting valid regex which might be desirable.

Is the library Synchronous or Asynchronous

Can you help me confirm that multiple goroutines can use this library concurrently without any issues or is it supposed to be synchronous?

Cpu seems to be growing when multiple requests happening concurrently.
