Setup DSL

In order to use the Archeometer toolkit, we need some aliases and imports

alias Archeometer.Schema.{App, AppXRef, Module, Function, XRef, Behaviour}
alias Archeometer.Analysis.{DSM, Treemap, Clustering}
alias Archeometer.Analysis.Xref, as: XRefAnalysis
alias Archeometer.Analysis.Apps.Xref, as: AppXRefAnalysis
alias Archeometer.Graphs.Graphviz
alias Archeometer.Repo
import Archeometer.Query

Project structure

List of applications, their size (measured in lines of code) and their module count.

result =
  Repo.all(
    from(a in App,
      select: [
        name: a.name,
        num_mods: count(a.modules.id),
        num_lines: sum(a.modules.num_lines),
        num_ecto_schemas: sum(a.modules.has_ecto_schema)
      ],
      group_by: a.name,
      order_by: [desc: num_mods]
    )
  )

LiveBookUtils.to_data_table(result)

The total number of lines of code is

result.rows
|> Enum.map(&Enum.at(&1, 2))
|> Enum.sum()
