30. I am a storyteller!
31. CIDER: Inside The Brewery
33. A story about a different kind of cider…
34. Clojure Interactive Development Environment that Rocks
35. … for Emacs
36. Is Emacs the One True Editor that will bring balance to the Source?
37. Absolutely!
38. Primary Clojure dev environment (2015) Other 10% LT 5% fireplace 12% Cursive 27% CIDER 46%
39. –Nancy Pearcey “Competition is always a good thing. It forces us to do our best. A monopoly renders people complacent and satisfied with mediocrity.”
40. Near future (optimistic) Other 10% CIDER 90%
41. Near future (worst case) Cursive 34% Other 15% CIDER 51%
42. Customer Testimonials
43. “Using CIDER is exciting. You never know if cider-jack-in will work or not!” — Mich Hickey
44. I used to wonder a lot how to get an adrenaline rush - now I simply upgrade CIDER! — Alex Killer
45. CIDER’s learning curve is amazing! I’m still amazed it never ends! — Zach Hellman
46. Half the things in Emacs and CIDER seem magic to me. Every time I use them I feel like a wizard! — Anna Parenlicka
47. A not so long time ago in a galaxy not far away…
48. Java, C# and PHP ruled the dev world
49. The Lisp Masters from the Republic of Great Programmers were on the run
50. Lisps were out of fashion
53. A gentleman & a scholar
54. Clojure
55. Biggest Clojure problem at launch?
56. ((((((((((()))))))))))
57. 0 Clojure development environments
58. Emacs was the last Lisp stronghold
59. Emacs is the greatest Emacs Lisp dev environment
60. SLIME
61. Superior Lisp Interaction Mode for Emacs
62. SLIME Features • REPL • Interactive evaluation • Compilation notes • Code completion • Definition lookup • Documentation lookup • Apropos
63. SLIME Features • Debugger • Value inspector • Tracing • Find usages • Macroexpansion • Scratchpad • Minibuffer code evaluation
64. SLIME is an IDE
65. Interactive Development Environment
66. Programs are built in a very incremental manner
67. SLIME (Emacs Lisp) SWANK (Common Lisp) Clozure RPC LispWorks CMUCL ABCL SBCL Client Server Backends
69. clojure-mode & swank-clojure
70. SLIME (Emacs Lisp) SWANK (Common Lisp) swank-clojure
71. A star was born
72. In 2010 around 70% of the Clojurians were developing in Emacs!!!
73. swank-clojure • Requires knowledge of swank (Common Lisp) • Bundles a frozen SLIME version • Subpar features (e.g. debugger, inspector, find usages) • Monolithic (no swank plugins)
74. SLIME is a Common Lisp tool
76. Another esteemed gentleman & scholar
77. nREPL
78. A common foundation for Clojure development tools
79. •Load (compile) a Clojure source file •Evaluate a Clojure form •Interrupt evaluation •Read from the standard input
80. Extensible via middleware
82. nrepl.el
83. nrepl.el (Emacs Lisp) nREPL (Clojure)
84. A workhorse is retired
85. nrepl.el • lacked many SLIME features • relied heavily on evaluation of inlined code • made assumptions about the environment • flawed bencode parser
87. Don’t settle for good. Demand great!
88. –Phil Karlton “There are only two hard things in Computer Science: cache invalidation and naming things.”
90. Clojure Integrated Development Environment & REPL
91. Clojure Interactive Development Environment Reimagined
92. Clojure Interactive Development Environment that Rocks
94. CIDER Features • Interactive evaluation • Compilation notes • Code completion • Definition lookup • Documentation lookup • Apropos
95. CIDER Features • Value inspector • Command selector • Tracing • Macroexpansion • Debugger • Scratchpad • Minibuffer code evalution
96. CIDER Features • Javadoc support • Jump to Java definition • Jump to resource • Sanity-preserving stacktraces • clojure.test integration • namespace browser
97. CIDER Features • classpath browser • grimoire integration • dynamic indentation • dynamic font-locking • nREPL session manager • Smart namespace reloading • ClojureScript support
98. Extensions (are easy)
99. Refactoring support (clj-refactor + refactor-nrepl)
100. Demo Time
101. CIDER tastes better than SLIME
102. CIDER tastes better than some IDES
104. Bulgarian Liberation Day 2016
105. CIDER 0.11 (Bulgaria)
106. Require Clojure 1.7+
107. Require Java 7+
108. Run all loaded/project tests
109. Enlighten
112. Auto-injection of CIDER’s dependencies
114. Clojure/west 2016
115. CIDER 0.12 (Seattle)
116. Conditional breakpoints
117. Step-in while debugging
118. Test result improvements
119. Zenburn & Solarized support
120. cider-auto-test-mode
121. Eldoc improvements
122. Display docstring on mouse hover
124. Totally reorganized menus
128. One more thing…
129. A Real Manual
130. A Real Manual
132. http://cider.readthedocs.org/
133. CIDER 0.13 (California)
134. Eldoc improvements
137. Unified evaluation commands keymap
138. C-c C-v something
139. cider-eval-sexp-at-point
140. C-c C-v (C-)v
141. Tracking of evaluated expressions
144. “See also” section in doc buffers
146. A cornucopia of small additions and improvements
147. CIDER 0.14 (Berlin)

151. C-c C-t (C-)g
152. The usual mix of bug fixes, small additions and improvements
153. What’s still missing?
154. •Find usages •Built-in refactoring tooling •Better ClojureScript support •Support for the new Clojure socket REPL CIDER 1.0
155. Why CIDER?
156. Integrated Development Environment (a.k.a. IDE)
158. Emacs
164. Spacemacs
165. Emacs users know how to build productive Lisp workflows
166. •Emacs (ultimate Elisp dev env) •SLIME (and SLY) •Geiser •racket-mode •CIDER (obviously)
167. • paredit • smartparens • rainbow-delimiters • rainbow-identifiers • sexp-fu • paxedit • lispy
