+#+TITLE: Developer Workflow v Doom Emacs
+#+AUTHOR: Martin Sukaný
+#+DATE: [2026-02-24 Tue]
+#+OPTIONS: toc:3 num:t
+#+STARTUP: overview
+
+* Úvod
+
+Tento dokument popisuje kompletní vývojářský workflow v Doom Emacs pro jazyky a nástroje, které Martin používá: Perl, Python, Go, Ansible, Terraform a Podman/Dockerfile. Ke každému jazyku najdeš: co nainstalovat, klávesové zkratky, příklad workflow a odkaz na ukázkový soubor v =examples/=.
+
+* Instalace nástrojů
+
+Všechny nástroje se instalují přes Homebrew (macOS). Na Linuxu použij příslušný package manager.
+
+** Perl
+
+#+begin_src bash
+brew install perl
+cpanm Perl::Tidy Perl::Critic Perl::LanguageServer
+#+end_src
+
+- =perltidy= — formatter (SPC m f)
+- =perlcritic= — linter
+- =Perl::LanguageServer= — LSP backend (volitelné)
+
+** Python
+
+#+begin_src bash
+brew install python ruff pyright
+#+end_src
+
+- =ruff= — ultra-rychlý linter + formatter
+- =pyright= — type-checking LSP server
+
+** Go
+
+#+begin_src bash
+brew install go gopls
+go install golang.org/x/tools/cmd/goimports@latest
+#+end_src
+
+- =gopls= — oficiální Go LSP
+- =goimports= — formatter (gofmt + auto imports)
+
+** Ansible
+
+#+begin_src bash
+brew install ansible ansible-lint
+#+end_src
+
+- =ansible-lint= — linter pro playbooky (flycheck integrace)
+
+** Terraform
+
+#+begin_src bash
+brew install terraform terraform-ls
+#+end_src
+
+- =terraform-ls= — HashiCorp oficiální LSP server
+
+** Podman / Dockerfile
+
+#+begin_src bash
+brew install podman hadolint
+#+end_src
+
+- =hadolint= — Dockerfile linter (flycheck integrace)
+- =podman= — Docker-kompatibilní container runtime (daemonless)
+
+* Keybindings přehled
+
+Všechny keybindings jsou pod =SPC m= (localleader) — aktivní pouze v příslušném major mode.

+* Ansible — workflow
+
+** Co nainstalovat
+
+#+begin_src bash
+brew install ansible ansible-lint
+#+end_src
+
+** Keybindings
+
+| Zkratka   | Akce                          |
+|-----------+-------------------------------|
+| =SPC m r= | Spustit ansible-playbook      |
+| =] e=     | Další ansible-lint chyba      |
+| =SPC s p= | Grep v projektu (role, vars)  |
+
+** Příklad workflow
+
+1. Otevři playbook: =SPC p f= → =playbook.yml=
+2. Yaml-mode se aktivuje automaticky, ansible-lint přes flycheck
+3. Navigace: =SPC s i= pro imenu (task names)
+4. Spuštění: =SPC m r= — spustí =ansible-playbook playbook.yml=
+5. Lint chyby: =] e= / =[ e= pro navigaci
+
+** Ukázkový soubor
+
+Viz =[[file:../examples/ansible/playbook.yml][examples/ansible/playbook.yml]]= — demonstruje apt install, user create, template copy, handlers a vars.
+
+* Terraform — workflow
+
+** Co nainstalovat
+
+#+begin_src bash
+brew install terraform terraform-ls
+#+end_src
+
+** Keybindings
+
+| Zkratka   | Akce                    |

+| =SPC m p= | terraform plan          |
+| =gd=      | Go to definition (LSP)  |
+
+** Příklad workflow
+
+1. Nový projekt: vytvoř adresář, =main.tf= + =variables.tf=
+2. Init: =SPC m i= — stáhne providery
+3. LSP (terraform-ls): autocompletion pro resource typy, atributy, variables
+4. Format: =SPC m f= — terraform fmt (kanonický styl)
+5. Plan: =SPC m p= — ukáže co se změní
+6. Apply: v terminálu =terraform apply=
+
+** Ukázkové soubory
+
+Viz =[[file:../examples/terraform/main.tf][examples/terraform/main.tf]]= a =[[file:../examples/terraform/variables.tf][examples/terraform/variables.tf]]= — demonstrují null provider, resource, variable, output a validation.
+
+* Podman / Dockerfile — workflow
+
+** Co nainstalovat
+
+#+begin_src bash
+brew install podman hadolint
+podman machine init   # jednorázově
+podman machine start
+#+end_src
+
+** Keybindings
+
+| Zkratka   | Akce                              |
+|-----------+-----------------------------------|
+| =SPC m b= | podman build (zeptá se na tag)    |
+| =SPC m r= | podman run (zeptá se na image)    |
+| =] e=     | Další hadolint chyba              |
+
+** Příklad workflow
+
+1. Otevři =Dockerfile=: dockerfile-mode se aktivuje automaticky
+2. Hadolint: flycheck ukazuje best practices (DL3008, DL3059 atd.)
+3. Build: =SPC m b= → zadej tag (např. =myapp:latest=) → compile buffer
+4. Run: =SPC m r= → zadej image name → spustí container
+
+** Ukázkový soubor
+
+Viz =[[file:../examples/docker/Dockerfile][examples/docker/Dockerfile]]= — demonstruje multi-stage build, non-root user, HEALTHCHECK a layer caching.
+
+* Go — učení (začátečník)
+
+** Základní kroky
+
+1. Vytvoř projekt:
+   #+begin_src bash
+   mkdir myproject && cd myproject
+   go mod init myproject
+   #+end_src
+
+2. Struktura:
+   #+begin_example
+   myproject/
+   ├── go.mod
+   ├── main.go          # vstupní bod
+   ├── internal/         # interní balíčky
+   │   └── handler.go
+   └── pkg/              # veřejné balíčky
+       └── utils.go
+   #+end_example
+
+3. Spusť: =go run main.go= (nebo =SPC m r= v Emacsu)
+4. Test: =go test ./...= (nebo =SPC m t=)
+5. Build: =go build -o myapp= (nebo =SPC m b=)
+
+** Klíčové koncepty
+
+- =package main= + =func main()= = vstupní bod
+- Error handling: =if err != nil { return err }= (žádné exceptions)
+- Goroutines: =go func()= pro souběžnost
+- Channels: =ch := make(chan int)= pro komunikaci mezi goroutines
+- Interfaces: implicitní implementace (duck typing)
+
+** Příklad
+
+Viz =[[file:../examples/go/main.go][examples/go/main.go]]= pro funkční ukázku všech konceptů.

+
+** Compile buffer
+
+Všechny =SPC m r/t/b= příkazy používají Emacs =compile= — výstup se zobrazí v compile bufferu. Klávesy v compile bufferu:
+
+- =g= — znovu spustit
+- =q= — zavřít
+- =RET= na error řádku — skok na zdrojový kód
