* First working pass
- Runs prettier on save when in ruby-mode.
- Adds `node_modules/.bin/` to local `exec-path`
- This means project-local `prettier` executables are preferred
* Making ruby layer prettier formatting configurable
- Adds a variable to control whether prettier is used to format-on-save.
- Documents use, configuration, and keybindings in the README
* Add to CHANGELOG.develop
* Delete spurious comment
* Use prettier as a dependency only when config variable is present
Before the ruby layer was only requiring standalone lsp layer,
however with the latest changes dap support has been added
therefore I have updated the layer file to require the full
dap layer instead which in turn requires the lsp layer.
There was a edge case with the declaration of the `lsp` layer in `layers.el`
files.
The `hy` layer depends on the `python` layer which in turn depends on the `lsp`
layer if and only if the `python-backend` layer variable is set to `lsp`.
When the `hy` layer was declared first then it declares the `python` layer
without its layer variables, thus the `lsp` layer was not declared because the
`python-backend` variable was not set.
The fix is to gather all the layer dependencies and resolve them only after all
the used layers have been declared.
* new function `configuration-layer/declare-layer-dependencies`
* replace all calls to `configuration-layer/declare-layer` by the new function
except for distribution layers (we declare layer dependencies right away in
distribution layers)
