@defmodule[pollen/file]
|
|
|
|
A utility module that provides functions for working with Pollen source and output files. The tests rely on file extensions specified in @racket[pollen/world].
|
|
|
|
Pollen handles six kinds of source files:
|
|
|
|
@bold{Preprocessor}, with file extension @code[(format ".~a" world:preproc-source-ext)].
|
|
|
|
@bold{Markup}, with file extension @code[(format ".~a" world:markup-source-ext)].
|
|
|
|
@bold{Template}, with file extension @code[(format ".~a" world:template-source-ext)].
|
|
|
|
@bold{Null}, with file extension @code[(format ".~a" world:null-source-ext)].
|
|
|
|
@bold{Scribble}, with file extension @code[(format ".~a" world:scribble-source-ext)].
|
|
|
|
For each kind of Pollen source file, the corresponding output file is generated by removing the extension from the name of the source file. So the preprocessor source file @code["default.css.pp"] would become @code["default.css"]. Scribble files work differently — the corresponding output file is the source file but with an @racket[html] extension rather than @racket[scrbl]. So @code["pollen.scrbl"] would become @code["pollen.html"].

Test whether @racket[_v] is a path representing a source file of the specified type, or is the output path for an existing source file of the specified type. In other words, @racket[has/is-preproc-source?] is equivalent to @racket[(or (preproc-source? v) (has-preproc-source? v))].

Convert an output path @racket[_p] into the source path of the specified type that would produce this output path. This function simply generates a path for a file — it does not ask whether the file exists.
