- sqlite3. a little overkill.
|

- json file. a little underkill.
|
||||
|
||||
what am I doing. should there even be a system like this? what about just letting anyone add anything? i think we're big enough that we shouldn't go moderation less and i can also help guarantee things are runnable and maintainable, this way.
|
||||
|
||||
i have a gut feeling that involving SQL here is bad. I like the flat file approach for requesting that something be added to core; those are easy to review and tweak, but after that, what to do? right now the town launcher consumes a directory of flat files to create the command hierarchy. i could keep that code the same. the ultimate issue is having to have the corresponding executable. right now, that might be a bash wrapper that i write; it could be a compiled executable; it could be a script someone else writes; as of now, it doesn't seem like it can be a symlink which i think is good.
|
||||
|
||||
several of the wrapper scripts are just calling the executable path and passing args; i think i should just do that from go.
|
||||
|
||||
so we'll have: /town/requests/contrib to store requests to add. once added, they will go to /town/commands/contrib as a yaml file with no need for a corresponding executable.
|
||||
|
||||
competing with this, i want a `town wild` command that can call any executable in a world writeable dir. because it's funny
