Pursuit

Name: pursuit
Brand: pursuit
SKU: //purescript/pursuit
Rating: 2.1025 (141 reviews)

Pursuit hosts API documentation for PureScript packages. It lets you search by package, module, and function names, as well as approximate type signatures.

Pursuit is currently deployed at https://pursuit.purescript.org.

Information for package authors can be found at https://pursuit.purescript.org/help.

Development

It's recommended to use

stack

: http://docs.haskellstack.org.

Build

To build in development mode:

$ stack build

To build in production mode:

$ stack build --flag pursuit:-dev

Develop

To iterate quickly during development, you can use

ghci

$ stack ghci

Once the REPL has loaded, you can reload the code and then update the web server:

> :l DevelMain
> update

Web server

To run the web server on http://localhost:3000:

$ stack exec pursuit

You might want to add some content to the database (see Database), otherwise you will not be able to browse any packages. The database will be regenerated from this data source before the server starts listening; this can take a short time depending on how much data you have.

Database

Pursuit currently uses the filesystem as a database, since it requires no setup and it makes it easy to use Git and GitHub for backing up. The data directory is set via an environment variable (see Configuration, the default is

data

If you need some sample packages to work with, you can clone the pursuit-backups repo and copy the packages you want to the

verified/

directory. This is more convenient than manually uploading each package.

Database structure

The database structure is as follows:

/
  cache/
    packages/
      purescript-prelude/
        0.1.0/
          index.html
          docs/
            Prelude/
              index.html
  verified/
    purescript-prelude/
      0.1.0.json
      0.1.1.json

The

cache/

directory has files that mirror the URL structure of the web application, and contains files which do not change and may be served as-is without forwarding the request on to the Yesod application. See Handler.Caching for more details.

The

verified/

directory stores uploaded packages. Each package has its own directory, and then there is a JSON file for each version. These JSON files each contain a serialized

Package GithubUser

; see Language.PureScript.Docs.Types in the compiler for details about these types.

The backup process simply involves rsyncing everything in the

verified/

directory into a git repository, making a commit, and pushing it to GitHub.

Configuration

All configuration is done at startup via environment variables. The relevant code is in the Settings module.

All configuration variable names start with

PURSUIT_

(eg,

PURSUIT_APPROOT

). All configuration variables are optional; for development, it is fine to just run

stack exec pursuit

leaving them all unset.

See

src/Settings.hs

for more details.

Assets
