0:00:00.512,0:00:17.222
(musica de jazz)

0:00:17.222,0:00:20.166
Sandi: Então você pensaria que escrever

0:00:20.166,0:00:23.288
código orientado a objetos [br]fosse difícil.

0:00:23.288,0:00:26.661
Tudo que precisa fazer é[br]olhas nossos apps, certo?

0:00:26.661,0:00:29.972
Temos boas intenções, [br]e quase sempre escrevemos

0:00:29.972,0:00:35.261
códigos que podemos vir a[br]odiar.

0:00:35.261,0:00:36.965
E quando mais eu penso [br]nisso, vejo que,

0:00:36.965,0:00:39.449
meu trabalho é pensar em [br]como escrever código melhor.

0:00:39.449,0:00:42.598
E quanto mais penso,[br]mais acho que

0:00:42.598,0:00:47.340
todos os problemas, tem uma[br]mesma solução simples

0:00:47.340,0:00:49.463
e agora quando pessoas me perguntam

0:00:49.463,0:00:51.254
como escrever código [br]orientado a objetos,

0:00:51.254,0:00:54.771
eu dou-lhes uma pequena dica.

0:00:54.771,0:00:58.425
Eu digo "criar coisas menores", é só isso.

0:00:58.425,0:01:00.593
Criar classes menores, métodos menores,

0:01:00.593,0:01:04.931
e deixar-lhes saber o mínimo possível [br]um sobre o outro.

0:01:04.931,0:01:06.640
E ultimamente estou em uma missão

0:01:06.640,0:01:08.234
Tenho tido essa obsessão [br]nos últimos meses,

0:01:08.234,0:01:10.483
e é sobre condicionais.

0:01:10.483,0:01:11.448
Tem muito código por aí

0:01:11.448,0:01:12.867
com condicionais feios nele,

0:01:12.867,0:01:15.685
e ando me questionando [br]quando eu deveria substituir

0:01:15.685,0:01:17.874
trocar condicionais por objetos pequenos

0:01:17.874,0:01:19.634
e como eu deveria fazer isso

0:01:19.634,0:01:22.594
e o que aconteceria com meu código [br]se eu fizesse isso.

0:01:22.594,0:01:24.378
Eu estava muito confiante [br]em Miami em novembro

0:01:24.378,0:01:26.970
e eu tive essa obsessão em Jim Weirich,

0:01:26.970,0:01:29.650
quem alguns de vocês [br]provavelmente conheceram,

0:01:29.650,0:01:33.449
e ele me direcionou para o 'Gilded Rose'.

0:01:33.449,0:01:34.879
Isso é um 'Kata', [br]aparentemente é

0:01:34.879,0:01:37.226
muito conhecido, [br]mas eu não saio muito,

0:01:37.226,0:01:38.838
então eu [br](risos)

0:01:38.838,0:01:40.629
nunca tinha ouvido disso.

0:01:40.629,0:01:43.689
É tão famoso que você pode[br]simplesmente botar no Google

0:01:43.689,0:01:46.729
e achar uma explicação do problema,[br]mas eu não fiz isso.

0:01:46.729,0:01:48.379
Eu queria tratar esse [br]problema como

0:01:48.379,0:01:50.345
se fosse um problema de produção mesmo,

0:01:50.345,0:01:51.973
e que minha única informação

0:01:51.973,0:01:54.152
fosse o teste e o código.

0:01:54.152,0:01:56.337
Então eu olhei para o dele.

0:01:56.337,0:01:58.391
Eu baixei o repositório dele,

0:01:58.391,0:01:59.317
e olhei para o problema,

0:01:59.317,0:02:02.330
e tinha tanta interesse nele [br]que tirei ideias

0:02:02.330,0:02:06.776
da minha palestra de hoje.

0:02:06.776,0:02:09.574
Eu alterei o código dele só um pouco,

0:02:09.574,0:02:11.256
mas só para ser [br]mais fácil de falar

0:02:11.256,0:02:13.688
Isso realmente é a 'Gilded Rose Kata',

0:02:13.688,0:02:14.514
então, vamos.

0:02:14.514,0:02:17.368
Tem a classe 'Gilded Rose', e essa[br]é a estrutura

0:02:17.368,0:02:20.454
Ela tem atributos para nome, qualidade[br]e dias restantes

0:02:20.454,0:02:22.326
ela initializa valores,

0:02:22.326,0:02:24.934
e tem um método "tick".

0:02:24.934,0:02:27.527
Agora aqui tem o método 'tick', [br]não, na verdade

0:02:27.527,0:02:32.836
isso é apenas a primeira metade dele, [br]aqui tem o resto.

0:02:32.836,0:02:34.336
Eu sei que não dá para ler isso

0:02:34.336,0:02:36.229
Nem tente, mesmo se conseguir, ok?

0:02:36.229,0:02:37.384
Aqui é o método inteiro.

0:02:37.384,0:02:38.999
Eu só quero que vocês tenham uma ideia

0:02:38.999,0:02:39.845
do tamanho e forma dele.

0:02:39.845,0:02:43.255
É um 'if' de 43 linhas.

0:02:43.255,0:02:45.441
E para mim isso é muito, muito difícil,

0:02:45.441,0:02:48.752
mas eu sou conhecida por[br]ser boolean-impedida.

0:02:48.752,0:02:50.440
(risos)

0:02:50.440,0:02:52.344
Eu sei que é subjetivo o meu senso de[br]quão dificil

0:02:52.344,0:02:55.268
de entender algo. [br]E isso possivelmente é errado

0:02:55.268,0:02:57.330
então em vez disso eu usei algumas métricas.

0:02:57.330,0:03:00.513
Analisei ele usando a métrica "Flog".

0:03:00.513,0:03:02.476
"Flog" é uma métrica. [br]Ok, o que é uma métrica?

0:03:02.476,0:03:06.391
Uma métrica é uma ideia "crowdsource" sobre alguma coisa.

0:03:06.391,0:03:09.619
Ok? Eu tenho minha própria opinião [br]sobre quanto isso é complexo,

0:03:09.619,0:03:12.563
mas eu posso usar a sabedoria-da-multidão [br]dessa métrica,

0:03:12.563,0:03:14.658
a métrica Flog, que anota....

0:03:14.658,0:03:17.250
É uma métrica ABC, então anota atribuições,

0:03:17.250,0:03:18.789
'branches', e condicionais.

0:03:18.789,0:03:20.660
Ela simplesmente conta coisas e soma-las.

0:03:20.660,0:03:21.957
Pontuações maiores são piores.

0:03:21.957,0:03:23.890
Elas indicam código mais complexo,

0:03:23.890,0:03:25.240
código que vai ser mais difícil

0:03:25.240,0:03:26.951
a entender e raciocinar.

0:03:26.951,0:03:30.454
Então, Flog disse que a classe GildedRose registrou 50,

0:03:30.454,0:03:33.611
e aquele método "tick" ganhou 45.

0:03:33.611,0:03:36.121
(lamentação)[br]Dói, né?

0:03:36.121,0:03:38.153
Então Flog disse que é complicado,

0:03:38.153,0:03:40.169
mas antes de continuar eu quero introduzir

0:03:40.169,0:03:44.370
uma métrica muito subjetiva [br]sobre complexidade.

0:03:44.370,0:03:45.686
Então, passo muito tempo esses dias

0:03:45.686,0:03:51.200
indo para lugares e olhando código [br]sobre qual eu não sei nada.

0:03:51.200,0:03:52.641
Pessoas me ligam, e vou pro escritório deles,

0:03:52.641,0:03:54.305
e passo alguns dias.

0:03:54.305,0:03:55.943
E como você poderia imaginar,

0:03:55.943,0:03:59.749
ninguém me liga se as coisas [br]estão indo bem.

0:03:59.749,0:04:01.800
(risos)[br]Né?

0:04:01.800,0:04:03.593
E quando eu chegar, eles não me pedem

0:04:03.593,0:04:06.650
para olhar o código do[br]qual eles tem orgulho.

0:04:06.650,0:04:09.304
Eles me pedem para olhar as [br]partes mais hediondas,

0:04:09.304,0:04:11.178
as coisas que tem contextos meio longos

0:04:11.178,0:04:13.650
e complexos na história.

0:04:13.650,0:04:16.584
Código que tem saído completamente [br]do controle.

0:04:16.584,0:04:19.509
E as explicações não são apenas [br]longas e confusas

0:04:19.509,0:04:21.750
porque o problema é difícil,

0:04:21.750,0:04:22.490
mas eles fazem aquilo que [br]todos nós fazemos,

0:04:22.490,0:04:24.504
você sabe aquilo que faz quando precisa

0:04:24.504,0:04:26.406
explicar um pouco de código que você escreveu

0:04:26.406,0:04:28.416
de qual você tem vergonha?

0:04:28.416,0:04:30.489
Você não apenas explica como funciona.

0:04:30.489,0:04:31.559
Você se sente obrigado a explicar

0:04:31.559,0:04:34.914
todos os motivos por ter ficado assim.[br](risos) Né?

0:04:34.914,0:04:37.155
Podem rir. Eu faço. Eu sei que vocês[br]também fazem, né?

0:04:37.155,0:04:38.594
Simplesmente dói. Odiamos isso.

0:04:38.594,0:04:40.177
Então essas explicações são longas

0:04:40.177,0:04:41.367
e confusas e tem muitas

0:04:41.367,0:04:44.332
informações paralelas

0:04:44.332,0:04:46.199
E chega um ponto, eu entendo...

0:04:46.199,0:04:47.449
mas chega um ponto durante toda

0:04:47.449,0:04:50.210
explicação quando eu começo a [br]me sentir igual aquele cachorro,

0:04:50.210,0:04:54.720
Ginger, no desenho do Gary Larson.

0:04:54.720,0:04:56.483
quando começa a virar "blah, blah, blah,"

0:04:56.483,0:04:58.474
Sandi "blah, blah, blah"[br](risos)

0:04:58.474,0:05:00.400
E de repente eu volto

0:05:00.400,0:05:01.512
para ouvir eles dizendo

0:05:01.512,0:05:03.556
então, o que você acha que [br]deveríamos fazer

0:05:03.556,0:05:07.211
sobre essa linha de código?[br](risos)

0:05:07.211,0:05:08.937
E antigamente me assustava muito

0:05:08.937,0:05:10.801
Senti como se precisasse entender tudo

0:05:10.801,0:05:12.931
para poder ajudar com alguma coisa.

0:05:12.931,0:05:14.371
Mas depois de algumas viagens,

0:05:14.371,0:05:15.956
eu percebi que tem algo muito

0:05:15.956,0:05:17.413
simples que poderia fazer para me ajudar

0:05:17.413,0:05:19.977
a identificar o que eles poderiam [br]se beneficiar modificando.

0:05:19.977,0:05:24.242
Eu chamo isso do "teste vesgo".[br](risos)

0:05:24.242,0:05:25.862
É assim que funciona:

0:05:25.862,0:05:29.173
Aperte os olhos, se incline

0:05:29.173,0:05:30.856
e olhe o código.

0:05:30.856,0:05:36.329
Buscamos por mudanças[br]na forma (risos)

0:05:36.329,0:05:39.701
e mudanças de cor.

0:05:41.270,0:05:44.208
Mudanças da forma quer dizer [br]que temos condicionais aninhados

0:05:44.208,0:05:45.640
e são difíceis de racionalizar.

0:05:45.640,0:05:48.890
Mudanças de cor dizem que seu código está

0:05:48.890,0:05:50.337
em níveis diferentes de abstração,

0:05:50.337,0:05:52.343
e querem dizer que a história que conta

0:05:52.343,0:05:53.685
vai ser difícil a seguir.

0:05:53.685,0:05:55.512
Agora, o que é sobre esse código?

0:05:55.512,0:05:56.977
Bem, ele tem 16 condicionais "if",

0:05:56.977,0:05:58.570
algumas delas são negadas,

0:05:58.570,0:06:00.730
e conectam algo com um "&",

0:06:00.730,0:06:01.559
tem 3 Strings mágicos, que são usados em todo lugar,

0:06:01.559,0:06:04.554
e vários números mágicos,

0:06:04.554,0:06:06.210
nem sei quantos.[br](risos)

0:06:06.210,0:06:07.956
Agora, pelo menos tem testes.

0:06:07.956,0:06:08.856
Ah, desculpe, aqui são os Strings mágicos.

0:06:08.856,0:06:11.655
Essas três coisas:

0:06:11.655,0:06:13.365
Brie, Sulfuras, e Backstage passes,

0:06:13.365,0:06:17.797
sei lá o que isso quer dizer.

0:06:17.797,0:06:21.632
E tem testes e eles passam.

0:06:21.632,0:06:24.820
Agora, tem seis testes pulados, certo?[br](risos)

0:06:24.820,0:06:26.934
Então sei lá o que é isso.

0:06:26.934,0:06:31.153
Então eu abro o código e só [br]olho esse primeiro teste.

0:06:31.153,0:06:32.736
Ah, desculpe, os testes são relacionados[br]as Strings mágicas

0:06:32.736,0:06:34.185
exceto desse grupo que é sobre

0:06:34.185,0:06:37.712
algo que se chama "Normal",

0:06:37.712,0:06:40.370
que nunca é mencionada nas condicionais.[br](risos)

0:06:40.370,0:06:41.410
Eu suspeito que tem um "else"

0:06:41.410,0:06:42.976
em algum lugar que importa, certo?

0:06:42.976,0:06:46.199
Então eu abro o teste e olho nele.

0:06:46.199,0:06:50.410
Aqui tem um, são todos assim.

0:06:50.410,0:06:51.622
Estou vendendo algo, certo?

0:06:51.622,0:06:55.106
Presumindo um GildedRose [br]que tem esse nome,

0:06:55.106,0:06:59.704
atributo e qualidade, [br]esses são nossos três attr_readers,

0:06:59.704,0:07:02.305
quando eu dou 'tick', nesse caso, [br]qualidade baixa por um,

0:07:02.305,0:07:03.224
dias sobrando baixa por um,

0:07:03.224,0:07:04.258
ambos baixam por um.

0:07:04.258,0:07:06.563
É como seu eu estivesse vendendo leite,

0:07:06.563,0:07:10.377
ou ovos, ou queijo ou algo [br]que tem validade,

0:07:10.377,0:07:12.625
que vai expirar, onde eles [br]ficam ruins em alguma data.

0:07:12.625,0:07:15.145
Então, ainda estou explorando,

0:07:15.145,0:07:17.576
ainda nem sei qual é meu trabalho,

0:07:17.576,0:07:22.850
e olho para os três testes pulados,

0:07:22.850,0:07:23.279
e tem algo que se chama "Conjurado",[br](risos)

0:07:23.279,0:07:24.872
e todos seguem a mesma linha,

0:07:24.872,0:07:26.809
todos os testes parecem que supondo isso

0:07:26.809,0:07:30.138
quando eu dou "tick", vejo essa mudança.

0:07:30.138,0:07:33.457
E agora eu percebo, caramba,

0:07:33.457,0:07:36.948
eu preciso modificar esse código.[br](risos)

0:07:36.948,0:07:41.961
Então eu tentei, eu tentei,

0:07:41.961,0:07:43.121
muito obedientemente, eu tentei, mas foi uma falha miserável.

0:07:43.121,0:07:44.704
Eu não consegui.

0:07:44.704,0:07:47.920
Aquele condicional de 43 linhas me venceu.

0:07:47.920,0:07:49.123
Toda vez que eu tentei, eu tipo abri [br]um teste Conjurado

0:07:49.123,0:07:51.940
eu fui fazer uma mudança [br]naquele condicional

0:07:51.940,0:07:53.129
para fazer o teste passar, [br]quebraria mais algo.

0:07:53.129,0:07:54.793
Gastei horas nisso.

0:07:54.793,0:07:56.916
Agora, eu fui prejudicada, [br]mas realmente, foi difícil.

0:07:56.916,0:07:58.743
Seria difícil para você também, eu acho.

0:07:58.743,0:08:00.308
Então, se mudar aquele condicional

0:08:00.308,0:08:02.297
fosse tão difícil, você precisa perguntar,

0:08:02.297,0:08:03.457
por que eu estava tentando? Por que eu tentei fazer,

0:08:03.457,0:08:09.145
o que me levou a tentar alterar

0:08:09.145,0:08:12.456
aquele pedação de código incrívelmente complicado.

0:08:12.456,0:08:13.634
E a resposta é que me senti que eu deveria.

0:08:13.634,0:08:16.720
E isso é o que acontece, né?

0:08:16.720,0:08:17.610
Você escreve um código, e alguém pede uma mudança.

0:08:17.610,0:08:18.279
O que nos fazemos?

0:08:18.279,0:08:20.743
Você roda o código procurando

0:08:20.743,0:08:22.495
um código que é parecido com

0:08:22.495,0:08:24.657
a coisa nova que está tentando fazer,

0:08:24.657,0:08:25.368
e você coloque o código aí.

0:08:25.368,0:08:28.480
É assim que agimos.

0:08:28.480,0:08:30.615
Novatos mais, eles tem medo de criar novos objetos,

0:08:30.615,0:08:32.515
então eles só coloquem mais código aonde conseguem

0:08:32.515,0:08:34.283
achar algo parecido com aquilo que estão tentando adicionar,

0:08:34.283,0:08:36.948
e se aquele lugar já tem um "if",

0:08:36.948,0:08:38.590
eles adicionam mais um galho, né?

0:08:38.590,0:08:40.111
É assim que funciona.

0:08:40.111,0:08:41.288
E o que acontece é, a tendência natural

0:08:41.288,0:08:42.460
é que código cresce,

0:08:42.460,0:08:43.465
e cresce, e cresce.

0:08:43.465,0:08:44.416
E chega um ponto, né?

0:08:44.416,0:08:46.306
Ele cresce, e cresce, e cresce.

0:08:46.306,0:08:48.115
E chega um ponto em que vira,

0:08:48.115,0:08:50.536
e naquele ponto é tão grande que

0:08:50.536,0:08:53.216
você não consegue imaginar colocando código em outro lugar.
