shell-history's Issues

ZSH history file can't be compatible in Chinese

refer: https://www.zsh.org/mla/users/2011/msg00154.html

When you read zsh history for some chinese word, it will give a mistaken code like '迃�惸�一段中惶��'

try this

echo "这是一段中文"
tail -n -10 ~/.zsh_history

Redundant `extraPaths` option

I don't see any use of this extraPaths option It's also not documented in the readme. It should be removed I guess!

shell-history/index.js

Line 38 in 0374d99

if (options.extraPaths) {

// made sense now :p

Why not shellHistory.path?

In the readme I see

console.log(shellHistory().path);

Does that not first enumerate the entire history (shellHistory(), a potentially lengthy operation) and then get the .path property from the result?

Why not compute the path to the history first and story it on the module.exports itself, allowing one to do

console.log(shellHistory.path);

.zsh_history file not found

Here's the error:

str.trim.split.map.Array.from.map.fp.reduce.module.exports.opts (node_modules/shell-history/index.js:60:18)
    module.exports (index.js:6:15)

This code caused it:

'use strict';

const shellHistory = require('shell-history');

module.exports = function (replaceMe) {
  console.log(shellHistory());
  return replaceMe;
};

Isolating the issue to just the getPath function:

node
> const h = require('shell-history')
undefined
> h.path()
undefined

I have an expected and non-empty .zsh_history location:

> os.homedir()
'/Users/dawsonbotsford'

 ~  cat /Users/dawsonbotsford/.zsh_history

Support Fish shell

Should add this path path.join(homeDir, '.config/fish/fish_history') to the paths array, but not sure of the format of the history file. Any Fish users wanna help out?
