Set for GitHub Actions to check for update everyday.
When you add or update the dependabot.yml file, this triggers an immediate check for version updates. Any options that also affect security updates are used the next time a security alert triggers a pull request for a security update.

Normally a single spell checker can't find all the mistakes or check all types of code.
These mistakes were found by another spell checker inside my editor with a more manual sift / find.

Run on pull request only.
Use a shell script to check for trailing whitespace in all files.
Fail if trailing whitespace is found.

Official -> "The individual jobs in a workflow can interact with (and compromise) other jobs. For example, a job querying the environment variables used by a later job, writing files to a shared directory that a later job processes, or even more directly by interacting with the Docker socket and inspecting other running containers and executing commands in them.
This means that a compromise of a single action within a workflow can be very significant, as that compromised action would have access to all secrets configured on your repository, and can use the GITHUB_TOKEN to write to the repository. Consequently, there is significant risk in sourcing actions from third-party repositories on GitHub. "

It used to return `mrb_ssize` but its size may differ from `mrb_int`,
e.g. `MRB_INT64` on `MRB_32BIT` architecture.

shuujii/avoid-possibility-of-reading-uninitialized-areas-in-h_check_modified
Avoid possibility of reading uninitialized areas in `h_check_modified()`
|
|
In `h_check_modified()`, in the case of `MRB_NO_BOXING`, `ht_ea()` or
`ht_ea_capa()` for AR may read uninitialized area. Therefore, do not use
those macros for AR in `MRB_NO_BOXING` (but in the case of `MRB_64BIT`,
`ht_ea_capa()` is the same as `ar_ea_capa()`, so use it).

Binary gems description added, along with a few cosmetic changes.
|
|
Binary gems are mrbgems that set `spec.bins` in their `mrbgem.rake`,
and usually their names are prefixed with `mruby-bin-`.
|
|
Especially description regarding the build process and `build` directory
structures, along with some typo fixes and cosmetic changes.
