Installation

How do I install this?

npm install trie-cli-myfatemi04

This is hosted in the NPM registry under trie-cli-myfatemi04.

After installing, the CLI is accessible with the command trie-cli.

Testing

How do I know if the Trie works?

trie-cli test tests.txt

This code allows you to input a file for testing purposes.

Each test case is split by a blank line. The first line is the command to be executed, and the second line is the optional condition to check for.

Conditions can be eq <JSON value> or neq <JSON value>. For arrays, eq checks that the expected and resulting arrays have the same size and that all values in the expected array are present in the resulting array. neq is not supported for arrays.

Example run-through of a test:

tests.txt

reset

insert hello
EQ true

insert hey

insert hellloo

display

complete hel
EQ ["hello", "hey"]

Run trie-cli test tests.txt

Output:

<root> ▾
 h ▾
  he ▾
   hel ▾
    hell ▾
     helll ▾
      helllo ▾
       hellloo
     hello
   hey
Test 1 / 2 => OK
Test 2 / 2 => Expected hey in results, not found
Result: 1 / 2
Non-test commands: 3
