# pathsd
This repository contains the *pathsd* project.
*pathsd* is a small CLI utility to manage the `PATH` enironment variable.
## Building and installing
*pathsd* is written in Nim programming language. To build it, you need to
install the compiler. Consult
[nim documentation](https://nim-lang.org/install.html) for instructions on
installing nim on your OS. The required version is 2.0.0 or newer.
To build *pathsd*, issue the following command:
```
$ make
```
The built binary will be placed in `build/pathsd`. To install, copy it
somewhere.
## Usage
*pathsd* requires at least one directory of _parts_ to operate on, e.g.
```
paths.d/
├── 01-bilbo
└── 02-homebrew
```
Each of the files should have one or more lines, each line being a single
entry in the rendered `PATH` variable.
Running the program with such a directory would yield the following result:
```
$ pathsd paths.d/
export PATH="/Users/bilbo/opt/bin:/opt/homebrew/bin:/opt/homebrew/sbin":$PATH
```
You can specify multiple directories. They'll be processed one by one in the
order specified on the command line.
The program is best used in your shell's startup file, e.g.
```bash
eval $(pathsd paths.d/)
```
At the time of writing, only `bash` is supported.
## Author
*pathsd* is developed by [Tomek Wójcik](https://www.bthlabs.pl/)
## License
*pathsd* is licensed under the MIT License.
