Overriding Dependencies

pesde has several ways to override or patch dependencies in your project.

Dependency Overrides

Dependency overrides allow you to replace a dependency of a dependency with a different version or package.

Let’s say you have a project with the following dependencies:

pesde.toml
[dependencies]
foo = { name = "acme/foo", version = "^1.0.0" }

But foo depends on bar 1.0.0, and you want to use bar 2.0.0 instead. You can override the bar dependency in your pesde.toml file:

pesde.toml
[dependencies]
foo = { name = "acme/foo", version = "^1.0.0" }


[overrides]
"foo>bar" = { name = "acme/bar", version = "^2.0.0" }

Now, when you run pesde install, bar 2.0.0 will be used instead of 1.0.0.

Overrides are also able to use aliases to share the specifier you use for your own dependencies:

pesde.toml
[dependencies]
foo = { name = "acme/foo", version = "^1.0.0" }
bar = { name = "acme/bar", version = "^2.0.0" }


[overrides]
"foo>bar" = "bar"

This is the same as if you had written:

pesde.toml
[dependencies]
foo = { name = "acme/foo", version = "^1.0.0" }
bar = { name = "acme/bar", version = "^2.0.0" }


[overrides]
"foo>bar" = { name = "acme/bar", version = "^2.0.0" }

You can learn more about the syntax for dependency overrides in the reference.

Patching Dependencies

Patching allows you to modify the source code of a dependency.

To patch a dependency, you can use the pesde patch and pesde patch-commit commands.

Let’s say you have the following dependency in your pesde.toml file:

pesde.toml
[target]
environment = "luau"


[dependencies]
foo = { name = "acme/foo", version = "^1.0.0" }

And you want to patch foo to fix a bug. You can run the following command:

Terminal window
pesde patch "acme/[email protected] luau"


# done! modify the files in the directory, then run `pesde patch-commit /x/y/z`
# to apply.
# warning: do not commit these changes
# note: the pesde.toml file will be ignored when patching

pesde will copy the source code of foo to a temporary directory, in this case /x/y/z. You can then modify the files in this directory. Once you’re done, run pesde patch-commit /x/y/z to apply the changes.

This will create a patch within the patches directory of your project, and add an entry to [patches]. Then, next time you run pesde install, the patch will be applied to the dependency.
