31. CIDER: Inside The Brewery

32. None

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

51. None

52. 2007

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

68. 2008

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

75. 2010

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

81. 2012

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

86. 2013

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.”
89. None

90. Clojure Integrated Development Environment & REPL

91. Clojure Interactive Development Environment Reimagined

92. Clojure Interactive Development Environment that Rocks

93. None

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
