Introduction

The fs module provides filesystem functions to Hilbish. While Lua's standard library has some I/O functions, they're missing a lot of the basics. The fs library offers more functions and will work on any operating system Hilbish does.

Functions

<hr class='my-4 text-neutral-400 dark:text-neutral-600'>
<div id='abs'>
<h4 class='text-xl font-medium mb-2'>
fs.abs(path) -> string
<a href="#abs" class='heading-link'>
	<i class="fas fa-paperclip"></i>
</a>
</h4>

Returns an absolute version of the path.
This can be used to resolve short paths like .. to /home/user.

Parameters

string *path*

<hr class='my-4 text-neutral-400 dark:text-neutral-600'>
<div id='basename'>
<h4 class='text-xl font-medium mb-2'>
fs.basename(path) -> string
<a href="#basename" class='heading-link'>
	<i class="fas fa-paperclip"></i>
</a>
</h4>

Returns the "basename," or the last part of the provided path. If path is empty,
. will be returned.

Parameters

string *path*
Path to get the base name of.

<hr class='my-4 text-neutral-400 dark:text-neutral-600'>
<div id='cd'>
<h4 class='text-xl font-medium mb-2'>
fs.cd(dir)
<a href="#cd" class='heading-link'>
	<i class="fas fa-paperclip"></i>
</a>
</h4>

Changes Hilbish's directory to dir.

Parameters

string *dir*
Path to change directory to.

<hr class='my-4 text-neutral-400 dark:text-neutral-600'>
<div id='dir'>
<h4 class='text-xl font-medium mb-2'>
fs.dir(path) -> string
<a href="#dir" class='heading-link'>
	<i class="fas fa-paperclip"></i>
</a>
</h4>

Returns the directory part of path. If a file path like
~/Documents/doc.txt then this function will return ~/Documents.

Parameters

string *path*
Path to get the directory for.

<hr class='my-4 text-neutral-400 dark:text-neutral-600'>
<div id='glob'>
<h4 class='text-xl font-medium mb-2'>
fs.glob(pattern) -> matches (table)
<a href="#glob" class='heading-link'>
	<i class="fas fa-paperclip"></i>
</a>
</h4>

Match all files based on the provided pattern.
For the syntax' refer to Go's filepath.Match function: https://pkg.go.dev/path/filepath#Match

Parameters

string *pattern*
Pattern to compare files with.

Example

--[[
	Within a folder that contains the following files:
	a.txt
	init.lua
	code.lua
	doc.pdf
]]--
local matches = fs.glob './*.lua'
print(matches)
-- -> {'init.lua', 'code.lua'}

<hr class='my-4 text-neutral-400 dark:text-neutral-600'>
<div id='join'>
<h4 class='text-xl font-medium mb-2'>
fs.join(...path) -> string
<a href="#join" class='heading-link'>
	<i class="fas fa-paperclip"></i>
</a>
</h4>

Takes any list of paths and joins them based on the operating system's path separator.

Parameters

string *path* (This type is variadic. You can pass an infinite amount of parameters with this type.)
Paths to join together

Example

-- This prints the directory for Hilbish's config!
print(fs.join(hilbish.userDir.config, 'hilbish'))
-- -> '/home/user/.config/hilbish' on Linux

<hr class='my-4 text-neutral-400 dark:text-neutral-600'>
<div id='mkdir'>
<h4 class='text-xl font-medium mb-2'>
fs.mkdir(name, recursive)
<a href="#mkdir" class='heading-link'>
	<i class="fas fa-paperclip"></i>
</a>
</h4>

Creates a new directory with the provided name.
With recursive, mkdir will create parent directories.

Parameters

Name of the directory

boolean *recursive*
Whether to create parent directories for the provided name

Example

-- This will create the directory foo, then create the directory bar in the
-- foo directory. If recursive is false in this case, it will fail.
fs.mkdir('./foo/bar', true)

<a href="#pipe" class='heading-link'>

</a>
</h4>

Returns a pair of connected files, also known as a pipe.
The type returned is a Lua file, same as returned from io functions.

Parameters

This function has no parameters.

<hr class='my-4 text-neutral-400 dark:text-neutral-600'>
<div id='readdir'>
<h4 class='text-xl font-medium mb-2'>

<a href="#readdir" class='heading-link'>
	<i class="fas fa-paperclip"></i>
</a>
</h4>

Returns a list of all files and directories in the provided path.

Parameters

local inspect = require 'inspect'

local stat = fs.stat '~'
print(inspect(stat))
