A maneira mais fácil de fazê-lo é: + +------------------------------------------------ +$ git config --global user.name "Seu Nome Vem Aqui" +$ git config --global user.email voce@seudominio.exemplo.com +------------------------------------------------ + + +Importando um novo projeto +----------------------- + +Assuma que você tem um tarball project.tar.gz com seu trabalho inicial. +Você pode colocá-lo sob controle de revisão git da seguinte forma: + +------------------------------------------------ +$ tar xzf project.tar.gz +$ cd project +$ git init +------------------------------------------------ + +Git irá responder + +------------------------------------------------ +Initialized empty Git repository in .git/ +------------------------------------------------ + +Você agora iniciou seu diretório de trabalho--você deve ter notado um +novo diretório criado, com o nome de ".git". + +A seguir, diga ao git para gravar um instantâneo do conteúdo de todos os +arquivos sob o diretório corrente (note o '.'), com 'git-add': + +------------------------------------------------ +$ git add . +------------------------------------------------ + +Este instantâneo está agora armazenado em uma área temporária que o git +chama de "index" ou índice. Você pode armazenar permanentemente o +conteúdo do índice no repositório com 'git-commit': + +------------------------------------------------ +$ git commit +------------------------------------------------ + +Isto vai te pedir por uma mensagem de commit. Você agora gravou sua +primeira versão de seu projeto no git. + +Fazendo mudanças +-------------- + +Modifique alguns arquivos, e, então, adicione seu conteúdo atualizado ao +índice: + +------------------------------------------------ +$ git add file1 file2 file3 +------------------------------------------------ + +Você está agora pronto para fazer o commit. Você pode ver o que está +para ser gravado usando 'git-diff' com a opção --cached: + +------------------------------------------------ +$ git diff --cached +------------------------------------------------ + +(Sem --cached, o comando 'git-diff' irá te mostrar quaisquer mudanças +que você tenha feito mas ainda não adicionou ao índice.) Você também +pode obter um breve sumário da situação com 'git-status': + +------------------------------------------------ +$ git status +# On branch master +# Changes to be committed: +# (use "git reset HEAD <file>..." to unstage) +# +# modified: file1 +# modified: file2 +# modified: file3 +# +------------------------------------------------ + +Se você precisar fazer qualquer outro ajuste, faça-o agora, e, então, +adicione qualquer conteúdo modificado ao índice. Finalmente, grave suas +mudanças com: + +------------------------------------------------ +$ git commit +------------------------------------------------ + +Isto irá novamente te pedir por uma mensagem descrevendo a mudança, e, +então, gravar a nova versão do projeto. + +Alternativamente, ao invés de executar 'git-add' antes, você pode usar + +------------------------------------------------ +$ git commit -a +------------------------------------------------ + +o que irá automaticamente notar quaisquer arquivos modificados (mas não +novos), adicioná-los ao índices, e gravar, tudo em um único passo. + +Uma nota em mensagens de commit: Apesar de não ser exigido, é uma boa +idéia começar a mensagem com uma simples e curta (menos de 50 +caracteres) linha sumarizando a mudança, seguida de uma linha em branco +e, então, uma descrição mais detalhada. Ferramentas que transformam +commits em email, por exemplo, usam a primeira linha no campo de +cabeçalho Subject: e o resto no corpo. + +Git rastreia conteúdo, não arquivos +---------------------------- + +Muitos sistemas de controle de revisão provêem um comando `add` que diz +ao sistema para começar a rastrear mudanças em um novo arquivo. O +comando `add` do git faz algo mais simples e mais poderoso: 'git-add' é +usado tanto para arquivos novos e arquivos recentemente modificados, e +em ambos os casos, ele tira o instantâneo dos arquivos dados e armazena +o conteúdo no índice, pronto para inclusão do próximo commit. + +Visualizando história do projeto +----------------------- + +Em qualquer ponto você pode visualizar a história das suas mudanças +usando + +------------------------------------------------ +$ git log +------------------------------------------------ + +Se você também quer ver a diferença completa a cada passo, use + +------------------------------------------------ +$ git log -p +------------------------------------------------ + +Geralmente, uma visão geral da mudança é útil para ter a sensação de +cada passo + +------------------------------------------------ +$ git log --stat --summary +------------------------------------------------ + +Gerenciando "branches"/ramos +----------------- + +Um simples repositório git pode manter múltiplos ramos de +desenvolvimento. Para criar um novo ramo chamado "experimental", use + +------------------------------------------------ +$ git branch experimental +------------------------------------------------ + +Se você executar agora + +------------------------------------------------ +$ git branch +------------------------------------------------ + +você vai obter uma lista de todos os ramos existentes: + +------------------------------------------------ + experimental +* master +------------------------------------------------ + +O ramo "experimental" é o que você acaba de criar, e o ramo "master" é o +ramo padrão que foi criado pra você automaticamente. O asterisco marca +o ramo em que você está atualmente; digite + +------------------------------------------------ +$ git checkout experimental +------------------------------------------------ + +para mudar para o ramo experimental. Agora edite um arquivo, grave a +mudança, e mude de volta para o ramo master: + +------------------------------------------------ +(edita arquivo) +$ git commit -a +$ git checkout master +------------------------------------------------ + +Verifique que a mudança que você fez não está mais visível, já que ela +foi feita no ramo experimental e você está de volta ao ramo master. + +Você pode fazer uma mudança diferente no ramo master: + +------------------------------------------------ +(edit file) +$ git commit -a +------------------------------------------------ + +neste ponto, os dois ramos divergiram, com diferentes mudanças feitas em +cada um. Para unificar as mudanças feitas no experimental para o +master, execute + +------------------------------------------------ +$ git merge experimental +------------------------------------------------ + +Se as mudanças não conflitarem, estará pronto. Se existirem conflitos, +marcadores serão deixados nos arquivos problemáticos exibindo o +conflito; + +------------------------------------------------ +$ git diff +------------------------------------------------ + +vai exibir isto. Após você editar os arquivos para resolver os +conflitos, + +------------------------------------------------ +$ git commit -a +------------------------------------------------ + +irá gravar o resultado da unificação. Finalmente, + +------------------------------------------------ +$ gitk +------------------------------------------------ + +vai mostrar uma bela representação gráfica da história resultante. + +Neste ponto você pode remover seu ramo experimental com + +------------------------------------------------ +$ git branch -d experimental +------------------------------------------------ + +Este comando garante que as mudanças no ramo experimental já estão no +ramo atual. + +Se você desenvolve em um ramo ideia-louca, e se arrepende, você pode +sempre remover o ramo com + +------------------------------------- +$ git branch -D ideia-louca +------------------------------------- + +Ramos são baratos e fáceis, então isto é uma boa maneira de experimentar +alguma coisa. + +Usando git para colaboração +--------------------------- + +Suponha que Alice começou um novo projeto com um repositório git em +/home/alice/project, e que Bob, que tem um diretório home na mesma +máquina, quer contribuir. + +Bob começa com: + +------------------------------------------------ +bob$ git clone /home/alice/project myrepo +------------------------------------------------ + +Isso cria um novo diretório "myrepo" contendo um clone do repositório de +Alice. O clone está no mesmo pé que o projeto original, possuindo sua +própria cópia da história do projeto original. + +Bob então faz algumas mudanças e as grava: + +------------------------------------------------ +(editar arquivos) +bob$ git commit -a +(repetir conforme necessário) +------------------------------------------------ + +Quanto está pronto, ele diz a Alice para puxar as mudanças do +repositório em /home/bob/myrepo. Ela o faz com: + +------------------------------------------------ +alice$ cd /home/alice/project +alice$ git pull /home/bob/myrepo master +------------------------------------------------ + +Isto unifica as mudanças do ramo "master" do Bob ao ramo atual de Alice. +Se Alice fez suas próprias mudanças no intervalo, ela, então, pode +precisar corrigir manualmente quaisquer conflitos. (Note que o argumento +"master" no comando acima é, de fato, desnecessário, já que é o padrão.) + +O comando "pull" executa, então, duas operações: ele obtém mudanças de +um ramo remoto, e, então, as unifica no ramo atual. + +Note que, em geral, Alice gostaria que suas mudanças locais fossem +gravadas antes de iniciar este "pull". Se o trabalho de Bob conflita +com o que Alice fez desde que suas histórias se ramificaram, Alice irá +usar seu diretório de trabalho e o índice para resolver conflitos, e +mudanças locais existentes irão interferir com o processo de resolução +de conflitos (git ainda irá realizar a obtenção mas irá se recusar a +unificar --- Alice terá que se livrar de suas mudanças locais de alguma +forma e puxar de novo quando isso acontecer). + +Alice pode espiar o que Bob fez sem unificar primeiro, usando o comando +"fetch"; isto permite Alice inspecionar o que Bob fez, usando um símbolo +especial "FETCH_HEAD", com o fim de determinar se ele tem alguma coisa +que vale puxar, assim: + +------------------------------------------------ +alice$ git fetch /home/bob/myrepo master +alice$ git log -p HEAD..FETCH_HEAD +------------------------------------------------ + +Esta operação é segura mesmo se Alice tem mudanças locais não gravadas. +A notação de intervalo "HEAD..FETCH_HEAD" significa mostrar tudo que é +alcançável de FETCH_HEAD mas exclua tudo o que é alcançável de HEAD. +Alice já sabe tudo que leva a seu estado atual (HEAD), e revisa o que Bob +tem em seu estado (FETCH_HEAD) que ela ainda não viu com esse comando. + +Se Alice quer visualizar o que Bob fez desde que suas histórias se +ramificaram, ela pode disparar o seguinte comando: + +------------------------------------------------ +$ gitk HEAD..FETCH_HEAD +------------------------------------------------ + +Isto usa a mesma notação de intervalo que vimos antes com 'git log'. + +Alice pode querer ver o que ambos fizeram desde que ramificaram. Ela +pode usar a forma com três pontos ao invés da forma com dois pontos: + +------------------------------------------------ +$ gitk HEAD...FETCH_HEAD +------------------------------------------------ + +Isto significa "mostre tudo que é alcançável de qualquer um deles, mas +exclua tudo que é alcançável a partir de ambos". + +Por favor, note que essas notações de intervalo podem ser usadas tanto +com gitk quanto com "git log". + +Após inspecionar o que Bob fez, se não há nada urgente, Alice pode +decidir continuar trabalhando sem puxar de Bob. Se a história de Bob +tem alguma coisa que Alice precisa imediatamente, Alice pode optar por +separar seu trabalho em progresso primeiro, fazer um "pull", e, então, +finalmente, retomar seu trabalho em progresso em cima da história +resultante. + +Quando você está trabalhando em um pequeno grupo unido, não é incomum +interagir com o mesmo repositório várias e várias vezes. Definindo um +repositório remoto antes de tudo, você pode fazê-lo mais facilmente: + +------------------------------------------------ +alice$ git remote add bob /home/bob/myrepo +------------------------------------------------ + +Com isso, Alice pode executar a primeira parte da operação "pull" usando +o comando 'git-fetch' sem unificar suas mudanças com seu próprio ramo, +usando: + +------------------------------------- +alice$ git fetch bob +------------------------------------- + +Diferente da forma longa, quando Alice obteve de Bob usando um +repositório remoto antes definido com 'git-remote', o que foi obtido é +armazenado em um ramo remoto, neste caso `bob/master`. Então, após isso: + +------------------------------------- +alice$ git log -p master..bob/master +------------------------------------- + +mostra uma lista de todas as mudanças que Bob fez desde que ramificou do +ramo master de Alice. + +Após examinar essas mudanças, Alice pode unificá-las em seu ramo master: + +------------------------------------- +alice$ git merge bob/master +------------------------------------- + +Esse `merge` pode também ser feito puxando de seu próprio ramo remoto, +assim: + +------------------------------------- +alice$ git pull . remotes/bob/master +------------------------------------- + +Note que 'git pull' sempre unifica ao ramo atual, independente do que +mais foi passado na linha de comando. + +Depois, Bob pode atualizar seu repositório com as últimas mudanças de +Alice, usando + +------------------------------------- +bob$ git pull +------------------------------------- + +Note que ele não precisa dar o caminho do repositório de Alice; quando +Bob clonou seu repositório, o git armazenou a localização de seu +repositório na configuração do mesmo, e essa localização é usada +para puxar: + +------------------------------------- +bob$ git config --get remote.origin.url +/home/alice/project +------------------------------------- + +(A configuração completa criada por 'git-clone' é visível usando `git +config -l`, e a página de manual linkgit:git-config[1] explica o +significado de cada opção.) + +Git também mantém uma cópia limpa do ramo master de Alice sob o nome +"origin/master": + +------------------------------------- +bob$ git branch -r + origin/master +------------------------------------- + +Se Bob decidir depois em trabalhar em um host diferente, ele ainda pode +executar clones e puxar usando o protocolo ssh: + +------------------------------------- +bob$ git clone alice.org:/home/alice/project myrepo +------------------------------------- + +Alternativamente, o git tem um protocolo nativo, ou pode usar rsync ou +http; veja linkgit:git-pull[1] para detalhes. + +Git pode também ser usado em um modo parecido com CVS, com um +repositório central para o qual vários usuários empurram modificações; +veja linkgit:git-push[1] e linkgit:gitcvs-migration[7]. + +Explorando história +----------------- + +A história no git é representada como uma série de commits +interrelacionados. Nós já vimos que o comando 'git-log' pode listar +esses commits. Note que a primeira linha de cada entrada no log também +dá o nome para o commit: + +------------------------------------- +$ git log +commit c82a22c39cbc32576f64f5c6b3f24b99ea8149c7 +Author: Junio C Hamano <junkio@cox.net> +Date: Tue May 16 17:18:22 2006 -0700 + + merge-base: Clarify the comments on post processing. +------------------------------------- + +Nós podemos dar este nome ao 'git-show' para ver os detalhes sobre este +commit. + +------------------------------------- +$ git show c82a22c39cbc32576f64f5c6b3f24b99ea8149c7 +------------------------------------- + +Mas há outras formas de se referir aos commits. Você pode usar qualquer +parte inicial do nome que seja longo o bastante para identificar +unicamente o commit: + +------------------------------------- +$ git show c82a22c39c # os primeiros caracteres do nome são o bastante + # usualmente +$ git show HEAD # a ponta do ramo atual +$ git show experimental # a ponta do ramo "experimental" +------------------------------------- + +Todo commit normalmente tem um commit "pai" que aponta para o estado +anterior do projeto: + +------------------------------------- +$ git show HEAD^ # para ver o pai de HEAD +$ git show HEAD^^ # para ver o avô de HEAD +$ git show HEAD~4 # para ver o trisavô de HEAD +------------------------------------- + +Note que commits de unificação podem ter mais de um pai: + +------------------------------------- +$ git show HEAD^1 # mostra o primeiro pai de HEAD (o mesmo que HEAD^) +$ git show HEAD^2 # mostra o segundo pai de HEAD +------------------------------------- + +Você também pode dar aos commits nomes à sua escolha; após executar + +------------------------------------- +$ git tag v2.5 1b2e1d63ff +------------------------------------- + +você pode se referir a 1b2e1d63ff pelo nome "v2.5". Se você pretende +compartilhar esse nome com outras pessoas (por exemplo, para identificar +uma versão de lançamento), você deveria criar um objeto "tag", e talvez +assiná-lo; veja linkgit:git-tag[1] para detalhes. + +Qualquer comando git que precise conhecer um commit pode receber +quaisquer desses nomes. Por exemplo: + +------------------------------------- +$ git diff v2.5 HEAD # compara o HEAD atual com v2.5 +$ git branch stable v2.5 # inicia um novo ramo chamado "stable" baseado + # em v2.5 +$ git reset --hard HEAD^ # reseta seu ramo atual e seu diretório de + # trabalho a seu estado em HEAD^ +------------------------------------- + +Seja cuidadoso com o último comando: além de perder quaisquer mudanças +em seu diretório de trabalho, ele também remove todos os commits +posteriores desse ramo. Se esse ramo é o único ramo contendo esses +commits, eles serão perdidos. Também, não use 'git-reset' num ramo +publicamente visível de onde outros desenvolvedores puxam, já que vai +forçar unificações desnecessárias para que outros desenvolvedores limpem +a história. Se você precisa desfazer mudanças que você empurrou, use +'git-revert' no lugar. + +O comando 'git-grep' pode buscar strings em qualquer versão de seu +projeto, então + +------------------------------------- +$ git grep "hello" v2.5 +------------------------------------- + +procura por todas as ocorrências de "hello" em v2.5. + +Se você deixar de fora o nome do commit, 'git-grep' irá procurar +quaisquer dos arquivos que ele gerencia no diretório corrente. Então + +------------------------------------- +$ git grep "hello" +------------------------------------- + +é uma forma rápida de buscar somente os arquivos que são rastreados pelo +git. + +Muitos comandos git também recebem um conjunto de commits, o que pode +ser especificado de várias formas. Aqui estão alguns exemplos com 'git-log': + +------------------------------------- +$ git log v2.5..v2.6 # commits entre v2.5 e v2.6 +$ git log v2.5.. # commits desde v2.5 +$ git log --since="2 weeks ago" # commits das últimas 2 semanas +$ git log v2.5.. Makefile # commits desde v2.5 que modificam + # Makefile +------------------------------------- + +Você também pode dar ao 'git-log' um "intervalo" de commits onde o +primeiro não é necessariamente um ancestral do segundo; por exemplo, se +as pontas dos ramos "stable" e "master" divergiram de um commit +comum algum tempo atrás, então + +------------------------------------- +$ git log stable..master +------------------------------------- + +irá listar os commits feitos no ramo "master" mas não no ramo +"stable", enquanto + +------------------------------------- +$ git log master..stable +------------------------------------- + +irá listar a lista de commits feitos no ramo "stable" mas não no ramo +"master". + +O comando 'git-log' tem uma fraqueza: ele precisa mostrar os commits em +uma lista. Quando a história tem linhas de desenvolvimento que +divergiram e então foram unificadas novamente, a ordem em que 'git-log' +apresenta essas mudanças é irrelevante. + +A maioria dos projetos com múltiplos contribuidores (como o kernel +Linux, ou o próprio git) tem unificações frequentes, e 'gitk' faz um +trabalho melhor de visualizar sua história. Por exemplo, + +------------------------------------- +$ gitk --since="2 weeks ago" drivers/ +------------------------------------- + +permite a você navegar em quaisquer commits desde as últimas duas semanas +de commits que modificaram arquivos sob o diretório "drivers". (Nota: +você pode ajustar as fontes do gitk segurando a tecla control enquanto +pressiona "-" ou "+".) + +Finalmente, a maioria dos comandos que recebem nomes de arquivo permitirão +também, opcionalmente, preceder qualquer nome de arquivo por um +commit, para especificar uma versão particular do arquivo: + +------------------------------------- +$ git diff v2.5:Makefile HEAD:Makefile.in +------------------------------------- + +Você pode usar 'git-show' para ver tal arquivo: + +------------------------------------- +$ git show v2.5:Makefile +------------------------------------- + +Próximos passos +---------- + +Este tutorial deve ser o bastante para operar controle de revisão +distribuído básico para seus projetos. No entanto, para entender +plenamente a profundidade e o poder do git você precisa entender duas +idéias simples nas quais ele se baseia: + + * A base de objetos é um sistema bem elegante usado para armazenar a + história de seu projeto--arquivos, diretórios, e commits. + + * O arquivo de índice é um cache do estado de uma árvore de diretório, + usado para criar commits, restaurar diretórios de trabalho, e + armazenar as várias árvores envolvidas em uma unificação. + +A parte dois deste tutorial explica a base de objetos, o arquivo de +índice, e algumas outras coisinhas que você vai precisar pra usar o +máximo do git. Você pode encontrá-la em linkgit:gittutorial-2[7]. + +Se você não quiser continuar com o tutorial agora nesse momento, algumas +outras digressões que podem ser interessantes neste ponto são: + + * linkgit:git-format-patch[1], linkgit:git-am[1]: Estes convertem + séries de commits em patches para email, e vice-versa, úteis para + projetos como o kernel Linux que dependem fortemente de patches + enviados por email. + + * linkgit:git-bisect[1]: Quando há uma regressão em seu projeto, uma + forma de rastrear um bug é procurando pela história para encontrar o + commit culpado. Git bisect pode ajudar a executar uma busca binária + por esse commit. Ele é inteligente o bastante para executar uma + busca próxima da ótima mesmo no caso de uma história complexa + não-linear com muitos ramos unificados. + + * link:everyday.html[GIT diariamente com 20 e tantos comandos] + + * linkgit:gitcvs-migration[7]: Git para usuários de CVS. + +VEJA TAMBÉM +-------- +linkgit:gittutorial-2[7], +linkgit:gitcvs-migration[7], +linkgit:gitcore-tutorial[7], +linkgit:gitglossary[7], +linkgit:git-help[1], +link:everyday.html[git diariamente], +link:user-manual.html[O Manual do Usuário git] + +GIT +--- +Parte da suite linkgit:git[1]. diff --git a/Documentation/technical/api-run-command.txt b/Documentation/technical/api-run-command.txt index 2efe7a40be..b26c28133c 100644 --- a/Documentation/technical/api-run-command.txt +++ b/Documentation/technical/api-run-command.txt @@ -35,12 +35,32 @@ Functions Convenience functions that encapsulate a sequence of start_command() followed by finish_command().
