[](https://github.com/saleyn/util/actions/workflows/erlang.yml)
**Author** Serge Aleynikov
## Installation
- Add dependency in `rebar.config`:

{deps,
[% ...
{util, "~> 1.0"}
]}.
```

## Documentation
* See [project documentation](https://saleyn.github.io/util)
This project implements an extension of `EDoc` documentation by using the color scheme similar
to `GitHub`, and generate the `overview.edoc` from the `README.md`.
In order to use this feature, modify your `Makefile` to include:
```
-include build-aux/docs-addon.mk
build-aux/docs-addon.mk:
@echo "Fetching build-aux/docs-addon.mk" && \
mkdir -p build-aux && \
curl -s -o build-aux/docs-addon.mk https://raw.githubusercontent.com/saleyn/util/master/build-aux/docs-addon.mk
```
Also in your `rebar.config` add:
```
{edoc_opts, [{overview, "build-aux/overview.edoc"},
{stylesheet_file, "build-aux/edoc.css"},
{title, "Project title used by rebar and also inserted as title to the index.html"},
{keywords, "HTML meta keywords (comma-delimited) for search engine crawlers"},
...]}.
```
NOTE: the `keywords` option is not specific to `EDoc` but used by the HTML reformatting make
file `docs-addon.mk`.
This will add the following targets to your `Makefile`:
- `docs` - Make documentation from source code
- `gh-pages` - Create GitHub pages for the current project
- `get-version` - Show application release version from the `*.app.src` and `rebar.config`
- `set-version` - Set the version number for the above `(make set-version version=X.Y.Z)`
- `clean-docs` - Remove the generated files in the `doc` directory
## Elixir
To add functions from `user_default.erl` to Elixir's `iex` shell, add `~/.iex.exs` file
containing:
```
import :user_default
```
