# Cfn Lsp Extra
 [](CHANGELOG.md) [](https://codecov.io/gh/LaurenceWarne/cfn-lsp-extra)
An experimental cloudformation lsp server (with support for SAM templates) built on top of [cfn-lint](https://github.com/aws-cloudformation/cfn-lint) aiming to provide hovering, completion, etc. YAML and JSON are supported, though YAML has more features currently implemented (for example snippets) and will give a better experience. Trust me.

## Features
| Method | Status |
|-----------------------------------|----------------------------------------------------------------------------------------------------------------------|
| `textDocument/hover` | Done for resources, resource properties, subproperties and `!Ref`s. *TODO* `!GetAtt`s, intrinsic functions. |
| `textDocument/completion` | Done for resources, resource properties, subproperties, refs, !GetAtts and intrinsic functions. *TODO* `Fn::GetAtt`. |
| `textDocument/definition` | Done for `!Ref`s. *TODO* mappings. |
| `textDocument/publishDiagnostics` | Done through `cfnlint`. |
Also checkout the [changelog](/CHANGELOG.md).
## Installation
First install the executable, [`pipx`](https://pypa.github.io/pipx/) is recommended, but you can use `pip` instead if you like to live dangerously:
```bash
pipx install cfn-lsp-extra
```
Or get the bleeding edge from source:
```bash
pipx install git+https://github.com/laurencewarne/cfn-lsp-extra.git@$(git ls-remote git@github.com:laurencewarne/cfn-lsp-extra.git | head -1 | cut -f1)
```
Updating:
```bash
pipx upgrade cfn-lsp-extra
```
### Emacs
Install the [lsp-cfn.el](https://github.com/LaurenceWarne/lsp-cfn.el) package.
### Neovim
Make sure you're running at least `0.8`, then add the following in `~/.config/nvim/filetype.lua`:
```lua
vim.filetype.add {
pattern = {
['.*'] = {
priority = math.huge,
function(path, bufnr)
local line1 = vim.filetype.getlines(bufnr, 1)
local line2 = vim.filetype.getlines(bufnr, 2)
if vim.filetype.matchregex(line1, [[^AWSTemplateFormatVersion]] ) then
return 'yaml.cloudformation'
elseif vim.filetype.matchregex(line1, [[["']AWSTemplateFormatVersion]] ) or
vim.filetype.matchregex(line2, [[["']AWSTemplateFormatVersion]] ) then
return 'json.cloudformation'
end
end,
},
},
}
```
Then you can use [LanguageClient-neovim](https://github.com/autozimu/LanguageClient-neovim) to start the server on those file types:
```vim
let g:LanguageClient_serverCommands = {
\ 'yaml.cloudformation': ['~/.local/bin/cfn-lsp-extra'],
\ 'json.cloudformation': ['~/.local/bin/cfn-lsp-extra']
\ }
```
Patches documenting integration for other editors are very welcome!
## Alternatives
### [vscode-cfn-lint](https://github.com/aws-cloudformation/cfn-lint-visual-studio-code)
### [cfn-lint](https://github.com/aws-cloudformation/cfn-lint)
Note this is used by `cfn-lsp-extra` under the hood to generate [diagnostics](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#diagnostic). One difference with `cfn-lsp-extra` is that diagnostics will be refreshed every time you make a change to the document, in other words you don't need to save the file.
### [yamlls](https://github.com/redhat-developer/yaml-language-server)
You can use `yamlls` in conjunction with the Cloudformation schema at https://www.schemastore.org/json/ as an alternative. For Emacs, `lsp-mode` can install `yamlls` for you, from there you could do something like:
```elisp
(defun my-yamlls-cloudformation-setup ()
;; There's also one for serverless
(lsp-yaml-set-buffer-schema "https://raw.githubusercontent.com/awslabs/goformation/master/schema/cloudformation.schema.json")
(setq-local
lsp-yaml-custom-tags
["!And"
"!Base64"
"!Cidr"
"!Equals"
"!FindInMap sequence"
"!GetAZs"
"!GetAtt"
"!If"
"!ImportValue"
"!Join sequence"
"!Not"
"!Or"
"!Ref Scalar"
"!Ref"
"!Select"
"!Split"
"!Sub"
"!fn"]))
;; Using the mode defined by https://www.emacswiki.org/emacs/CfnLint
(add-hook 'cfn-yaml-mode-hook #'my-yamlls-cloudformation-setup)
(add-hook 'cfn-yaml-mode-hook #'lsp-deferred)
```
This will give you completions (and some support for value completions?), though no hover documentation.
