class Clayoven::Git

Git metadata information for the clayoven repository

Information from the git index via new is cheap, but metadata is expensive due to the git log --follow invocation.

Public Class Methods

new(tzmap) click to toggle source

Look at the git index immediately; accepts a Clayoven::Config#tzmap hashtable

# File lib/clayoven/git.rb, line 7
def initialize(tzmap)
  git_ns = `git diff --name-status @ 2>/dev/null`
  @tzmap = tzmap
  @untracked = `git ls-files --others --exclude-standard`.split "\n"
  if !git_ns.empty?
    git_index = git_ns.split("\n").map { |line| line.split("\t")[0..1] }
    git_mod_index = git_index.select { |idx| idx.first == "M" }
    @modified = git_mod_index.map(&:last)
    @added = (git_index - git_mod_index).map(&:last)
  else
    @modified = []
    @added = []
  end
end

toplevel() click to toggle source

Return the toplevel directory in the git tree, or an empty string

# File lib/clayoven/git.rb, line 23
def self.toplevel
  `git rev-parse --show-toplevel 2>/dev/null`.strip
end

Public Instance Methods

added?(file) click to toggle source

Indicates if a file was added, from git index

# File lib/clayoven/git.rb, line 33
def added?(file)
  @added.any?(file) || @untracked.any?(file)
end

added_or_modified?(file) click to toggle source

Indicates if any of the files in the list of files were added or modified, from git index

# File lib/clayoven/git.rb, line 43
def added_or_modified?(file)
  added?(file) || modified?(file)
end

any_added?(files) click to toggle source

Indicates if any of the files in the list of files were added, from git index

# File lib/clayoven/git.rb, line 38
def any_added?(files)
  files.any? { |file| added? file }
end

design_changed?() click to toggle source

Indicates if design/style.sass or design/script.js was changed

# File lib/clayoven/git.rb, line 54
def design_changed?
  modified?("design/style.sass") || modified?("design/script.js")
end

metadata(file) click to toggle source

Returns a [#{Last modified timestamp} # {Creation timestamp} #{Location strings}] The timestamps default to Time.now if the file hasn’t been committed. Expensive compared to HTML generation by Claytext.

# File lib/clayoven/git.rb, line 61
def metadata(file)
  dates =
    `git log --follow --format="%aD" --date=unix #{file} 2>/dev/null`.split(
      "\n"
    )
      .map { |d| Time.parse d }
  locs =
    dates.map { |d| d.strftime("%z") }.map { |tz| @tzmap[tz] }.flatten.uniq
  return Time.now, Time.now, locs unless dates.first

  lastmod = added_or_modified?(file) ? Time.now : dates.first
  [lastmod, dates.last, locs]
end

modified?(file) click to toggle source

Indicates if a file was modified, from git index

# File lib/clayoven/git.rb, line 28
def modified?(file)
  @modified.any?(file) || @untracked.any?(file)
end

template_changed?() click to toggle source

Indicates if the config or the template was changed, in a way that requires a full rebuild

# File lib/clayoven/git.rb, line 48
def template_changed?
  modified?("design/template.slim") || modified?(".clayoven/hidden") ||
    modified?(".clayoven/tz") || modified?(".clayoven/subtopics")
end
