Switched to @tryghost/logging instead of passing around the library. The main sticking points of this change are jobs. When jobs are launched we don't want them to use a separate @tryghost/logging instance because they would start parallel rotation jobs. @tryghost/logging v2.x passes all logs to the parent process if run in a child process, so that we can use the same patterns in jobs and the rest of the codebase.
- core/shared/i18n is no longer used. Remove it to prevent temptation!
- this class needs merging with the one in themes, but for now just co-locate them as that's quicker and easier
- we need the basePath concept for the main i18n class so we can pull it out into a module
- we already had this in the themeI18n class, so I just had to move it up
- also I added a default of __dirname, so we don't have to declare this constantly in the tests
- Reworking the location of i18n in boot has fixed the main error
- However, many of our tests depend on i18n being loaded but don't explicitly call init
- There are many ways we could fix this in our tests, but I don't want to spend more time on this now
- final preparation for moving i18n out of Ghost core
- logging is passed in via DI
- theme i18n needs a config value, but no need to pass all of config for one parameter, a better pattern is to pass the one value needed
- preparation for moving the base class out of Ghost
- refactored so that all the logic for file loading and fallbacks live in the base class
- theme i18n now only overrides init with the properties it needs, filepath generation and error handling
- this makes it much easier to move the i18n file out, and eventually have theme i18n live elsewhere too
- also prepares for using DI for logging
- when activating a theme, we need to load the current locale
- this request used to be buried deep in the themeI18n init call
- now we surface it in the bridge and pass it down, which is closer to what we want to do with eventually initialising the frontend
with everything it needs up front (or not initialising it, if it isn't needed)
- in the related helpers we depend on the site.locale value instead of proxy -> themeI18n -> settingsCache drastically simplifying the code and removing deep requires
- site.locale is updated via middleware and can be relied upon
- the core i18n library and theme i18n library have slightly different methods of getting a candidate string
- both of them use forms of jsonpath, meaning they both require jsonpath as a dependency
- to try to get to a point of being able to rip more things out of ghost, we want to have less dependencies
- so instead of overloading the method, we pass in a stringMode as an argument
- eventually we might not need an overloaded class for themeI18n at all, which would simplify the codebase
- preparation for using DI instead of requires, so we can move this out of Ghost
- have done this for both the main i18n and theme i18n file
- refactored the constructor
