struct Default{T}

Internal wrapper type that is meant to be used in situations where it is necessary to distinguish whether the user explicitly passed the same value as the default value to a keyword argument, or whether the keyword argument was not passed at all.

function foo(; kwarg = Default("default value"))
    if isa(kwarg, Default)
        # User did not explicitly pass a value for kwarg
    else kwarg === "default value"
        # User passed "default value" explicitly
check_strict_kw(strict) -> Nothing

Internal function to check if strict is a valid value for the keyword argument strict to makedocs. Throws an ArgumentError if it is not valid.


Calls git remote show $(remotename) to try to determine the main (development) branch of the remote repository. Returns master and prints a warning if it was unable to figure it out automatically.

root is the the directory where git gets run. varname is just informational and used to construct the warning messages.

is_strict(strict, val::Symbol) -> Bool

Internal function to check if strict is strict about val, i.e. if errors of type val should be fatal, according to the setting strict (as a keyword to makedocs).

Single-argument is_strict(strict) provides a curried function.

issubmodule(sub, mod)

Checks whether sub is a submodule of mod. A module is also considered to be its own submodule.

E.g. A.B.C is a submodule of A, A.B and A.B.C, but it is not a submodule of D, A.D nor A.B.C.D.

mdparse(s::AbstractString; mode=:single)

Parses the given string as Markdown using Markdown.parse, but strips away the surrounding layers, such as the outermost Markdown.MD. What exactly is returned depends on the mode keyword.

The mode keyword argument can be one of the following:

  • :single (default) – returns a single block-level object (e.g. Markdown.Paragraph or Markdown.Admonition) and errors if the string parses into multiple blocks.
  • :blocks – the function returns a Vector{Any} of Markdown blocks.
  • :span – Returns a Vector{Any} of span-level items, stripping away the outer block. This requires the string to parse into a single Markdown.Paragraph, the contents of which gets returned.

Returns a vector of parsed expressions and their corresponding raw strings.

Returns a Vector of tuples (expr, code), where expr is the corresponding expression (e.g. a Expr or Symbol object) and code is the string of code the expression was parsed from.

The keyword argument skip = N drops the leading N lines from the input string.

If raise=false is passed, the Meta.parse does not raise an exception on parse errors, but instead returns an expression that will raise an error when evaluated. parseblock returns this expression normally and it must be handled appropriately by the caller.

The linenumbernode can be passed as a LineNumberNode to give information about filename and starting line number of the block (requires Julia 1.6 or higher).

repo_root(file; dbdir=".git")

Tries to determine the root directory of the repository containing file. If the file is not in a repository, the function returns nothing.

The dbdir keyword argument specifies the name of the directory we are searching for to determine if this is a repostory or not. If there is a file called dbdir, then it's contents is checked under the assumption that it is a Git worktree or a submodule.


Find the path of a file relative to the source directory. root is the path to the directory containing the file file.

It is meant to be used with walkdir(source).

@docerror(doc, tag, msg, exs...)

Add tag to the doc.internal.errors array and log the message msg as an error (if tag matches the doc.user.strict setting) or warning.

  • doc must be the instance of Document used for the Documenter run
  • tag must be one of the Symbols in ERROR_NAMES
  • msg is the explanation of the issue to the user
  • exs... are additional expressions that will be included with the message; see @error and @warn
