6.4 Package Source Parsing

 (require pkg/name) package: base
The pkg/name library provides functions for parsing and normalizing a package source, especially for extracting a package name.

procedure

(package-source-format? v)  boolean?

  v : any/c
Returns #t if v is 'name , 'file, 'dir, 'github, 'file-url, 'dir-url, 'link, or 'static-link, and returns #f otherwise.

The 'link and 'static-link formats are the same as 'dir in terms of parsing, but they are treated differently for tasks such as package installation.

procedure

(package-source->name source [type])  (or/c #f string?)

  source : string?
  type : (or/c package-source-format? #f) = #f
Extracts the package name from a package source, where the package source type is inferred if type is #f. If a valid name cannot be inferred, the result is #f.

procedure

(package-source->name+type source [type])

  
(or/c #f string?)
(or/c package-source-format? #f)
  source : string?
  type : (or/c package-source-format? #f) = #f
Like package-source->name, but also returns the type of the source (which is useful when the type is inferred). If the source is not well-formed, the second result can be #f.
