formatjson5 is a command line tool, currently built and installed as a fuchsia developer tool (host-side only).
The binary is Rust-based, built using the json5format library. (json5format was originally developed by the Fuchsia team, within the Fuchsia source tree, but was later published as an independent Rust library, under crates.io, and is now imported into Fuchsia's third_party/rust_crates.)
json5format is the default formatter for some file extensions supported by the fuchsia multi- schema file formatter script, fx format-code. This script will automatically format known file types among the files in your most recent commit to the fuchsia source tree.
Run fx formatjson5 --help for command line usage documentation.
To add this project to your build, append --with //build/tools/formatjson5 to the fx set invocation.
formatjson5 is available at host-tools/formatjson5 in the build output path after an fx build invocation. This executable can also be launched via fx formatjson5.
For example, use the following command to review the command line options:
$ fx formatjson5 --help
Make sure the tests are added to your build by adding --with //build/packages:formatjson5 to your fx set invocation.
Host-side tests for the formatjson5 command can be manually launched by running:
$ fx test -o formatjson5
