hof / mod



hof/mod is a command for managing CUE and Hof modules. Use it to initialize a new module, set versioned dependencies, and fetch them with a single command.

$ hof help mod

hof mod is CUE dependency management based on Go mods.

### Module File

The module file holds the requirements for project.
It is found in cue.mod/module.cue	

---
// These are like golang import paths
//   i.e. github.com/hofstadter-io/hof
module: "<module-path>"
cue: "v0.5.0"

// Required dependencies section
require: {
  // "<module-path>": "<module-semver>"
  "github.com/hofstadter-io/ghacue": "v0.2.0"
  "github.com/hofstadter-io/hofmod-cli": "v0.8.1"
}

// Indirect dependencies (managed by hof)
indirect: { ... }

// Replace dependencies with local or remote
replace: {
  "github.com/hofstadter-io/ghacue": "github.com/myorg/ghacue": "v0.4.2"
  "github.com/hofstadter-io/hofmod-cli": "../mods/clie"
}

### Authentication and private modules

hof mod prefers authenticated requests when fetching dependencies.
This increase rate limits with hosts and supports private modules.
Both token and sshkey base methods are supported, with preferences:

1. Matching entry in .netrc
  machine github.com
  login github-token
  password <github-token-value>

2. ENV VARS for well known hosts.

  GITHUB_TOKEN
  GITLAB_TOKEN
  BITBUCKET_USERNAME / BITBUCKET_PASSWORD or BITBUCKET_TOKEN 

  The bitbucket method will depend on the account type and enterprise license.

3. SSH keys 

  the following are searched: ~/.ssh/config, /etc/ssh/config, ~/.ssh/id_rsa


### Usage

there are two main commands you will use, init & tidy

# Initialize the current folder as a module
hof mod init <module-path>     (like github.com/org/repo)

# Refresh dependencies, discovering any new imports
hof mod tidy

# Add a dependency
hof mod get github.com/hofstadter-io/hof@v0.6.8
hof mod get github.com/hofstadter-io/hof@v0.6.8-beta.6
hof mod get github.com/hofstadter-io/hof@latest   // latest semver
hof mod get github.com/hofstadter-io/hof@next     // next prerelease
hof mod get github.com/hofstadter-io/hof@main     // latest commit on branch

# Update dependencies
hof mod get github.com/hofstadter-io/hof@latest
hof mod get all@latest

# Symlink dependencies from local cache
hof mod link

# Copy dependency code from local cache
hof mod vendor

# Verify dependency code against cue.mod/sums.cue
hof mod verify

# This helpful output
hof mod help

Usage:
  hof mod [command]

Aliases:
  mod, m

Available Commands:
  clean       clean hof's module cache
  get         add a new dependency to the current module
  init        initialize a new module in the current directory
  link        symlink dependencies to cue.mod/pkg
  publish     publish a module
  tidy        recalculate dependencies and update mod files
  vendor      copy dependencies to cue.mod/pkg
  verify      verify integrity of dependencies

Flags:
  -h, --help   help for mod

Global Flags:
  -E, --all-errors               print all available errors

  -l, --path stringArray         CUE expression for single path component when placing data files
  -q, --quiet                    turn off output and assume defaults at prompts
  -d, --schema stringArray       expression to select schema to apply to data files
      --stats                    print generator statistics
  -0, --stdin-empty              A flag that ensure stdin is zero and does not block
  -t, --tags stringArray         @tags() to be injected into CUE code
  -U, --user-files stringArray   file globs to embed into the root value (<cue-path>=<file-glob>), use % as slash to trim before
  -v, --verbosity int            set the verbosity of output
      --with-context             add extra context for data files, usable in the -l/path flag
