@title[#:tag "raco-pollen"]{Using @exec{raco pollen}}
Racket provides centralized command-line options through @exec{raco} (short for @exec{racket command}, see @other-doc['(lib "scribblings/raco/raco.scrbl")]).
Once you install Pollen, you can access the following Pollen-specific commands through @racket[raco] using the subcommand @exec{raco pollen}.
@section{Making sure @exec{raco pollen} works}
Open a terminal window and type:
@terminal{
> raco pollen test}
If @exec{raco pollen} is installed correctly, you'll see:
@terminal{raco pollen is installed correctly}
But if you get:
@terminal{raco: Unrecognized command: pollen}
You'll need to fix the problem before proceeding, most likely by reinstalling Pollen (see @secref["Installation" #:doc '(lib "pollen/scribblings/pollen.scrbl")]).
If your error is like this:
@terminal{Unrecognized command: raco}
You have a deeper problem with your Racket installation (often a misconfiguration of @code{PATH}).
@section{@exec{raco pollen}}
Same as @exec{raco pollen help}.
@section{@exec{raco pollen help}}
Displays a list of available commands.
@section{@exec{raco pollen start}}
Start the project server from the current directory using the default port, which is the value of the parameter @racket[world:current-server-port] (by default, port @(format "~a" world:default-port)).
This command can be invoked with two optional arguments.
@racket[raco pollen start _path] will start the project server in @racket[_path] rather than the current directory.
@terminal{
> raco pollen start ~/path/to/project/}
@racket[raco pollen start _path _port] will start the project server in @racket[_path] using @racket[_port] rather than @racket[world:current-server-port]. This is useful if you want to have multiple project servers running simultaneously.
@terminal{
> raco pollen start ~/path/to/project/
> raco pollen start ~/path/to/project/scribblings 8088}
If you want to start in the current directory but with a different port, use @litchar{.} as the path:
@terminal{
> raco pollen start . 8088}
@section{@exec{raco pollen render}}
Render all preprocessor source files and then all pagetree files found in the current directory. If none of these files are found, a pagetree will be generated for the directory (which will include all source files) and then rendered.
This command can be invoked with extra arguments.
@racket[raco pollen render _directory] will perform the render described above, but in the specified directory.
Alternatively, the command can take a variable number of path arguments. @racket[raco pollen render _path ...] will render only the paths specified in @racket[_path ...]. Consistent with the usual command-line idiom, this can be a single path, a list of paths, or a pattern:
@terminal{
> raco pollen render foo.html.pm
> raco pollen render foo.html.pm bar.html.pm zam.css.pp
> raco pollen render *.html.pm}
Paths can also be specified as output rather than input paths, and the corresponding source paths will be discovered:
@terminal{
> raco pollen render foo.html
> raco pollen render foo.html bar.html zam.css}
The optional @exec{-t} or @exec{--target} switch specifies the render target for multi-output source files. If the target is omitted, the renderer will use whatever target appears first in @racket[(world:current-poly-targets)].
@terminal{
> raco pollen render -t pdf foo.poly.pm}
See also @seclink["raco-pollen-render-poly"].
@bold{Warning}: In all cases, the newly rendered output file will overwrite any previous output file.
@section{@exec{raco pollen publish}}
Make a copy of the project directory on the desktop, but without any source files or other Pollen-related files. (This function is pretty lame, and I invite suggestions for improvement.)
@racket[raco pollen publish _project-dir] will publish the project in @racket[_project-dir] onto the desktop in a folder called @racket[publish]. @bold{Warning}: if @racket[publish] already exists on the desktop, it will be overwritten.
@racket[raco pollen publish _project-dir _dest-dir] will publish the project in @racket[_project-dir] to @racket[_dest-dir] rather than the desktop. @bold{Warning}: if @racket[_dest-dir] already exists, it will be overwritten by the newly published directory.
If you're already in your project directory and want to publish somewhere other than the desktop, use @racket[raco pollen publish _. _dest-dir].
You can determine the files that get filtered out in a particular project by using @racket[world:current-unpublished-path?].
@section{@exec{raco pollen setup}}
Finds Pollen source files in the current directory, compiles them, and loads the results into the @seclink["Cache" #:doc '(lib "pollen/scribblings/pollen.scrbl")]. This will give you the snappiest performance during an interactive session with the project server.
Can also be invoked as @racket[raco pollen setup _directory], which will set up a different project @racket[_directory].
@section{@exec{raco pollen reset}}
Resets Pollen's @seclink["Cache" #:doc '(lib "pollen/scribblings/pollen.scrbl")] by deleting the cache directories.
Can also be invoked as @racket[raco pollen reset _directory], which will reset a different project @racket[_directory].
@section{@exec{raco pollen version}}
Would you believe this prints the Pollen version number.
