(For ZSH / BASH / FISH Shells)

Installation • Usage • Configuration • Uninstalling

</div>

Features

• Per Directory Environment Variables
• Auto Load .env files in Directories
• Auto Execute Commands in Directories
• Per Directory Aliases
• Works with any CD like Command

Installation

1. Install binary

cargo install cdwe

2. Init your shell

cdwe init zsh # zsh shells
cdwe init bash # bash shells
cdwe init fish # fish shells

3. Reload your shell and start using!

# check that env var gets set
cdwe /Users/synoet/dev/projecta
echo $IS_DEBUG

# check that env var gets unset
cdwe ..
echo $IS_DEBUG

Usage

Defining Per Directory Env Variables

---

You can explicitly define environment variables in two ways:

[[directory]]
path = "/Users/synoet/dev/project"
vars = {"IS_DEBUG" = "true", "IS_PROD" = "false"}

# or

[[directory]]
path = "/Users/synoet/dev/project"
vars = [
    {name="IS_DEBUG", value ="true"},
    {name="IS_PROD", value="false"}
]

path: the path to your directory you are configuring

vars: a map of env vars to set

By default env vars will also be loaded in subdirectories, in this example /Users/synoet/dev/project/src would also have IS_DEBUG and IS_PROD set

OR

[[env_variable]]
name = "IS_DEBUG"
value = "true"
dirs = [
  "/Users/synoet/dev/project1",
  "/Users/synoet/dev/project2"
]

Here you can define one env var for multiple directories.

name: Is the key of the env variable

value: is the value of the env variable

dirs: Is a list of directories to load this env var for

Loading From .env files

---

The directory object also takes a load_from field

[[directory]]
path = "/Users/synoet/dev/project"
vars = {"IS_DEBUG" = "true", "IS_PROD" = "false"}
load_from = [".env"]

load_from: List of .env file names to auto load in, these should be relative to the dir defined in path.

In this example we would try to load in a env file at /Users/synoet/dev/project/.env

Unlike per directory env vars, env files are only loaded in the exact matching directory not in subdirectories

OR

Similarly we can define a single env file for multiple directories

[[env_file]]
load_from = ".env"
dirs = [
  "/Users/synoet/dev/macro/macro-site/astro",
  "/Users/synoet/dev/macro/app-monorepo/packages/app"
]

Defining Aliases Per Directory

---

Here we can define aliases that will be set and unset as functions only in specific directories

[[directory]]
path = "/Users/synoet/dev/project"
vars = {"IS_DEBUG" = "true", "IS_PROD" = "false"}
load_from = [".env"]
aliases = [
    { name = "build", commands = ["yarn cache clean", "yarn build", "yarn package"] }
]

Here we define a build alias which will live only in /User/synoet/dev/project/* and all subdirectories.

aliases: a list of aliases to define for the directory

OR

[[alias]]
name = "build"
commands = ["yarn cache clean", "yarn build", "yarn package"]
dirs = [
    "/Users/synoet/dev/projecta",
    "/Users/synoet/dev/projectb"
]

Here you are defining the same alias for multiple directories.

Defining Auto Commands

---

Here we can define commands that will automatically run anytime we cd into a specific directory

[[directory]]
path = "/Users/synoet/dev/project"
vars = {"IS_DEBUG" = "true", "IS_PROD" = "false"}
load_from = [".env"]
aliases = [
    { name = "build", commands = ["yarn cache clean", "yarn build", "yarn package"] }
]
run = ["git fetch -p", "ls"]

In this case every time we enter /Users/synoet/dev/project cdwe will automatically run git fetch -p and ls

Auto Commands also require an exact match and don't propogate to subdirectories

OR

[[command]]
run = "git fetch -p"
dirs = [
  "/Users/synoet/dev/cdwe",
  "/Users/synoet/dev/macro/macro-api"
]

Configuration

Global Configuration Options

[config]
# Shell (Created during cdwe init <shell>)
shell = "zsh"
# Custom CD Command (defaults to cd)
cd_command = "z"
# Show alias hints on cd
alias_hints = true
# Show env hints on cd
env_hints = true
# shoe run hints on cd
run_hints = true

Example Configuration

[config]
cd_command = "z"
alias_hints = true
env_hints = true
command_hints = true
run_hints = true
shell = "zsh"

# Defined a directory
# Will have env var "TEST" set in this directory
# Will auto run "git fetch -p" whenever you cd into this dir
# Exposes the following aliases in that directory and sub dirs
[[directory]]
path = "/Users/synoet/dev/cdwe"
vars = { "TEST" = "testing" }
runs = ["git fetch -p"]
aliases = [
  { name = "build", commands = ["cargo build --release"]},
  { name = "run", commands = ["cargo run"]},
  { name = "ci", commands = ["cargo fmt", "cargo test"]}
]

# sets the "ENV_VAR" env var in the following directories
[[env_variable]]
name = "ENV_VAR"
value = "THIS IS A TEST"
dirs = [
  "/Users/synoet/dev/cdwe",
  "/Users/synoet/dev/ballast"
]

# auto loads from .env file in following directories
[[env_file]]
load_from = ".env"
dirs = [
  "/Users/synoet/dev/cdwe",
  "/Users/synoet/dev/project-api"
]

# will auto run the command "git fetch -p" in the following directories
[[command]]
run = "git fetch -p"
dirs = [
  "/Users/synoet/dev/cdwe",
  "/Users/synoet/dev/project-api"
]

Using CDWE Environment Variables in the paths

If you want to use something like $HOME or any other environment variable set in a path, you can do so by wrapping the environment variable inside of {{}}. Using $HOME as an example, you would do {{HOME}}. This can make using one cdwe.toml across many machines nice if you have different users but a similar directory structure for each user.

Uninstalling

1. Run cdwe-remove to clean up all shell artifacts

cdwe-remove #removes the `source <output>` from your .zshrc/.bashrc/.fish

zsh #reload your shell, use bash or fish if you use those.

2. Uninstall binary

cargo uninstall cdwe
