Build from Source

# Clone the repository
git clone <repository-url>
cd DevCli

# Build for current platform
make build

# Build for macOS (current architecture)
make build-macos

# Build for macOS (both amd64 and arm64)
make build-macos-all

# Build for all platforms
make build-all

Install

make install

Shell Completion (Tab Auto-completion)

DevKit supports tab completion for bash, zsh, fish, and PowerShell.

Zsh (macOS/Linux)

# Generate completion script
devcli completion zsh > ~/.devcli-completion.zsh

# Add to your ~/.zshrc
echo "source ~/.devcli-completion.zsh" >> ~/.zshrc

# Reload shell (yeni terminal açın veya)
exec zsh
# veya
source ~/.zshrc

Test Completion:

# Tab tuşuna basarak test edin:
devcli <TAB>              # completion, dev, file, net, help gösterir
devcli dev <TAB>          # base64, hash, ulid, uuid gösterir
devcli dev hash <TAB>     # md5, sha1, sha256, sha512 gösterir
devcli dev base64 <TAB>   # encode, decode gösterir
devcli dev uuid --<TAB>   # --version, --count, --output gösterir

Bash

# Generate completion script
devcli completion bash > ~/.devcli-completion.bash

# Add to your ~/.bashrc or ~/.bash_profile
echo "source ~/.devcli-completion.bash" >> ~/.bashrc

# Reload shell
source ~/.bashrc

Fish

# Generate completion script
devkit completion fish > ~/.config/fish/completions/devkit.fish

After setup, you can use Tab to auto-complete commands, subcommands, and flags!
