Practicalli Clojure LSP Configuration

Custom snippets in Clojure LSP format (EDN). Practicalli designed snippets to encourage communication of the code purpose.

Install

Clone the repository to the user level configuration location for Clojure LSP, either $XDG_CONFIG_HOME/clojure-lsp or if XDG_CONFIG_HOME is not set, $HOME/.config/clojure-lsp

Clojure LSP configuration

Include :extra-paths and :extra-deps from project & user level aliases in LSP classpath. e.g. support a custom user namespace in dev/user.clj

 :source-aliases #{:dev :test :env/dev :env/test :lib/reloaded}

Include Java Sources installed via Debian / Ubuntu package openjdk-17-source to support calls to Java Objects and Methods.

 :java
 {:jdk-source-uri       "file:///usr/lib/jvm/openjdk-17/lib/src.zip" ;;
  :home-path            nil ;; jdk-source-uri takes precedence
  :download-jdk-source? false}

Clean namespace ns forms but do not sort require names

 :clean {:automatically-after-ns-refactor true
         :ns-inner-blocks-indentation     :next-line
         :ns-import-classes-indentation   :next-line
         :sort {:ns      false
                :require false
                :import  false
                :import-classes {:classes-per-line 3} ;; -1 for all in single line
                :refer {:max-line-length 80}}}

Use ^private metadata for private function definitions rather than defn-

 :use-metadata-for-privacy? true

Location of cljfmt configuration for formatting, path relative to project root. The defaults for cljfmt are used, except :remove-consecutive-blank-lines? which is set to false to enable more readable code.

 :cljfmt-config-path "cljfmt.edn"

cljfmt configuration included example :indents rules for clojure.core, compojure, fuzzy rules and examples used by the Clojure LSP maintainer.

Custom snippets

Snippets created by Practicalli are documents in Practicalli Spacemacs

Docs / comments

• comment-heading - describe purpose of the namespace
• comment-separator - logically separate code sections, helps identify opportunities to refactor to other name spaces
• comment-section - logically separate large code sections with start and end line comments
• wrap-reader-comment - insert reader comment macro, #_ before current form, informing Clojure reader to ignore next form

Repl Driven Development

• rich-comment - comment block
• rich-comment-rdd - comment block with ignore :redefined-var for repl experiments
• rich-comment-hotload - comment block with add-libs code for hotloading libraries in Clojure CLI repl
• wrap-rich-comment - wrap current form with comment reader macro
• require-rdd - add a require expression, for adding a require in a rich comment block for RDD

Standard library functions

• def - def with docstring
• def- - private def with docstring
• defn - defn with docstring
• defn- private defn with docstring
• ns - namespace form with docstring

Clojure CLI deps.edn aliases

• deps-alias - add Clojure CLI alias
• deps-maven - add a maven style dependency
• deps-git - add a git style dependency using :git/sha
• deps-git-tag - as above including :git/tag
• deps-git-url - add git style dependency using git url (url taken from dependency name as it is typed - mirrored placeholder)
• deps-local - add a :local/root dependency

Requiring dependencies

• require-rdd - add a require expression, for adding a require in a rich comment block for RDD
• require - simple require
• require-refer - require with :refer
• require-as - require with :as alias
• use - creates a require rather than the more troublesome use

Unit testing

• deftest - creates a deftest with testing directive and one assertion
• testing - creates a testing testing directive and one assertion
• is - an assertion with placeholders for test function and expected results
