Setting hosts

To make GitStats work you need to set hosts after creating gitstats_object.

You can set GitLab host with set_gitlab_host() and GitHub host with set_github_host() or both.

When setting hosts you need to take into account:

Do you wish to connect to private or public hosts?
What scanning scope do you wish to set? Do you want to scan specific organizations or repositories or maybe whole git platforms?
Do you have tokens set up and stored in your environment variables that grant you access to APIs?

Public and private hosts

If you connect to public hosts you simply call set_github_host() or set_gitlab_host() function without specifying host parameter.

library(GitStats)
git_stats <- create_gitstats() %>%
  set_github_host(
    orgs = c("r-world-devs", "openpharma"),
    token = Sys.getenv("GITHUB_PAT")
  ) %>%
  set_gitlab_host(
    orgs = c("mbtests"),
    token = Sys.getenv("GITLAB_PAT_PUBLIC")
  )

If you wish to connect to internal GitHub or GitLab, you need to pass names of the hosts to host parameter. Remember also to have tokens set up properly for these hosts (on tokens read below).

git_stats <- create_gitstats() %>%
  set_github_host(
    host = "github.internal.com",
    orgs = c("org_1", "org_2", "org_3"),
    token = Sys.getenv("YOUR_GITHUB_PAT")
  ) %>%
  set_gitlab_host(
    host = "internal.host.com",
    orgs = c("internal_org"),
    token = Sys.getenv("YOUR_GITLAB_PAT")
  )

API versions

GitStats is configured to connect to GitHub API (version 3) and GitLab API (version 4).

Scanning scope

When setting hosts you choose what scanning scope of your GitStats will be:

organizations/groups - in this case you need to pass character arguments (names of organizations (in case of GitHub) or groups (in case of GitLab)) to orgs parameter.

git_stats <- create_gitstats() %>%
  set_github_host(
    orgs = c("r-world-devs", "openpharma"),
    token = Sys.getenv("GITHUB_PAT")
  ) %>%
  set_gitlab_host(
    orgs = c("mbtests"),
    token = Sys.getenv("GITLAB_PAT_PUBLIC")
  )

repositories - in this case you need to pass full names of repositories ({org_name}/{repo_name}) to the repos parameter.

git_stats <- create_gitstats() %>%
  set_github_host(
    repos = c("r-world-devs/GitStats", "r-world-devs/shinyCohortBuilder", "openpharma/DataFakeR"),
    token = Sys.getenv("GITHUB_PAT")
  ) %>%
  set_gitlab_host(
    repos = "mbtests/gitstatstesting",
    token = Sys.getenv("GITLAB_PAT_PUBLIC")
  )

whole hosts - this is possible for the time being only in case of private hosts, as public ones are deemed to be too large. To set whole Git platform to be scanned just set hosts without specifying orgs or repos. On the other hand, remember that to connect with internal host, you need to pass argument to host parameter.

git_stats <- create_gitstats() %>%
  set_github_host(
    host = "github.internal.com",
    token = Sys.getenv("YOUR_GITHUB_PAT")
  ) %>%
  set_gitlab_host(
    host = "internal.host.com",
    token = Sys.getenv("YOUR_GITLAB_PAT")
  )

Authorize your access with tokens

Remember to pass to your set_*_host() functions tokens that authorize access.

You can store your tokens in environment variables, e.g. defined in .Renviron file as GITHUB_PAT for GitHub and GITLAB_PAT for GitLab.

On how to create your tokens refer to GitHub API and GitLab API documentation.

When creating tokens you will be asked to set access scopes of the tokens. For GitStats to work you need tokens with given scopes:

[GitHub] public_repo, read:org and read:user,
[GitLab] read_api.

If you have your access tokens stored in environment variables with such names as GITHUB_PAT or GITHUB_PAT_* and GITLAB_PAT or GITLAB_PAT_* you do not need to specify them in set_*_host() functions, GitStats will automatically find them.

git_stats <- create_gitstats() %>%
  set_github_host(
    orgs = c("r-world-devs", "openpharma")
  ) %>%
  set_gitlab_host(
    orgs = c("mbtests")
  )
