Hugo provides a way to integrate Git data into your site.
|
|
|
|
|
|
## Prerequisites
|
|
|
|
1. The Hugo site must be in a Git-enabled directory.
|
|
1. The Git executable must be installed and in your system `PATH`.
|
|
1. Enable the GitInfo feature in Hugo by using `--enableGitInfo` on the command
|
|
line or by setting `enableGitInfo` to `true` in your site configuration.
|
|
|
|
## The GitInfo Object
|
|
|
|
The `GitInfo` object contains the following fields:
|
|
|
|
AbbreviatedHash
|
|
: abbreviated commit hash, e.g. `866cbcc`
|
|
|
|
AuthorName
|
|
: author name, respecting `.mailmap`
|
|
|
|
AuthorEmail
|
|
: author email address, respecting `.mailmap`
|
|
|
|
AuthorDate
|
|
: the author date
|
|
|
|
Hash
|
|
: commit hash, e.g. `866cbccdab588b9908887ffd3b4f2667e94090c3`
|
|
|
|
Subject
|
|
: commit message subject, e.g. `tpl: Add custom index function`
|
|
|
|
|
|
## Other Considerations
|
|
|
|
The Git integrations should be fairly performant, but it does add some time to the build, which depends somewhat on the Git history size.
|
|
|
|
The accuracy of data depends on the underlying local git respository. If the local repository is a *shallow clone*, then any file that hasn't been modified in the truncated history will default to data in the oldest commit. In particular, if the respository has been cloned using `--depth=1` then every file will the exact same `GitInfo` data -- that of the only commit in the repository.
|
|
|
|
In particular, many CI/CD systems such as [travis-ci.org](https://travis-ci.org) default to a clone depth of 50 which is unlikely to be deep enough. You can explicitly add back the missing history using using `git fetch --unshallow` or [make the initial checkout deeper](https://docs.travis-ci.com/user/customizing-the-build#Git-Clone-Depth).
