7.4 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.


(package-source-format? v)  boolean?

  v : any/c
Returns #t if v is 'name , 'file, 'dir, 'git, 'git-url, 'github, 'clone, '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. The 'clone and 'git-url formats are similarly the same as 'github or 'git in terms of parsing.

Changed in version of package base: Added 'git.
Changed in version Added 'clone.
Changed in version Added 'git-url.


(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.


  #:complain complain-proc 
  #:must-infer-name? must-infer-name?] 
  #:link-dirs? link-dir?) 
(or/c #f string?)
(or/c package-source-format? #f)
  source : string?
  type : (or/c package-source-format? #f) = #f
  complain-proc : (string? string? . -> . any) = void
  must-infer-name? : boolean? = #f
  link-dir? : boolean?
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.

The complain-proc function is applied when source is ill-formed. The arguments to complain-proc are source and an error message.

If must-infer-name? is true, then complain-proc is called if a valid name cannot be inferred from source.

If link-dirs? is true, then a directory path is reported as type 'link instead of 'dir.


(package-source->path source [type])  path?

  source : string?
  type : (or/c #f 'file 'dir 'link 'static-link) = #f
Converts a file or directory package source to a filesystem path.

The package-source->path function is different from string->path in the case that source starts with file://. Also, if type is 'dir, 'link, or 'static-link, then path->directory-path is used to ensure that the result path refers to a directory.

Added in version of package base.
