gitlab-haskell: A Haskell library for the GitLab web API

[ bsd3, git, library ] [ Propose Tags ]

This Haskell library queries and updates the database of a GitLab instance using the GitLab web API: https://docs.gitlab.com/ee/api/

It also features an API for writing Gitlab file hook applications

Run all GitLab actions with runGitLab:

runGitLab ::
 => GitLabServerConfig -- ^ the GitLab server details
 -> GitLab a           -- ^ the GitLab action
 -> IO a

For example:

myProjects <- runGitLab
     (defaultGitLabServer
         { url = "https://gitlab.example.com"
         , token="my_token"} )
     (searchUser "joe" >>= userProjects . fromJust)

Which uses the functions:

searchUser   :: Text -> GitLab (Maybe User)
userProjects :: User -> GitLab (Maybe [Project])
projectCommits :: Project -> GitLab [Commit]

This library can also be used to develop rule based GitLab file hooks that react in real time to GitLab events with:

receive :: [Rule] -> GitLab ()
class (FromJSON a) => SystemHook a where
  match   :: String -> (a -> GitLab ()) -> Rule
  matchIf :: String -> (a -> GitLab Bool) -> (a -> GitLab ()) -> Rule

For more details about the file hooks support: https://www.macs.hw.ac.uk/~rs46/posts/2020-06-06-gitlab-system-hooks.html

Unsurprisingly, this library is maintained on GitLab: https://gitlab.com/robstewart57/gitlab-haskell

[back to package description]

A Haskell library for the GitLab web API

This library interacts with a GitLab server's API. It supports queries about and updates to:

  • Branches
  • Commits
  • Groups
  • Issues
  • Jobs
  • Members
  • Merge requests
  • Pipelines
  • Projects
  • Repositories
  • Repository files
  • Users

The library parses JSON results into Haskell data types in the GitLab.Types module, allowing you to work with statically typed GitLab data with data types and functions that the library provides. E.g.

searchUser     :: Text -> GitLab (Maybe User)
userProjects   :: User -> GitLab (Maybe [Project])
projectCommits :: Project -> GitLab [Commit]

Example

Run all GitLab actions with runGitLab:

runGitLab ::
   => GitLabServerConfig
   -> GitLab a
   -> IO a

For example:

myProjects <-
  runGitLab
    (defaultGitLabServer
       { url = "https://gitlab.example.com"
       , token="my_token"} )
    (searchUser "joe" >>= userProjects . fromJust)

This library can also be used to implement rule based GitLab file system hooks that, when deployed a GitLab server, react in real time to GitLab events like project creation, new users, merge requests etc.

The rule based API for implementing file hooks is:

receive :: [Rule] -> GitLab ()

class (FromJSON a) => SystemHook a where
  match   :: String -> (a -> GitLab ()) -> Rule
  matchIf :: String -> (a -> GitLab Bool) -> (a -> GitLab ()) -> Rule

For more details about the file system hooks support, see post: GitLab automation with file hook rules.

For the complete gitlab-haskell API, see the hackage documentation.

The gitlab-tools command line tool for bulk GitLab transactions uses this library link.
