* commands: parse arguments with go-optRobin Jarry2023-10-281-8/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | Use the argument parsing framework introduced earlier to unify the parsing of (almost) all command options. Remove custom parsing code and to avoid extraneous types, add fields with `opt` tags on command structs that have options and arguments. Commands that take no argument do not need anything. Since the command objects now carry data, create a new temporary instance of them before passing them to opt.ArgsToStruct when executing a command. A few of the commands use specific semantics for parsing (:choose), or are delegating argument parsing to another function (:sort, :search, :filter). For these commands, simply add a dummy "-" passthrough argument. Since all commands still have the argument list (after split) nothing needs to be changed in this area. There should be no functional change besides the Usage strings and reported errors which are now generated automatically.

* app: export global functionsRobin Jarry2023-10-101-8/+8
| | | | | | | | | | | | | | | The single Aerc object is passed around in almost all command functions. This hinders readability. Store the single Aerc instance as a global variable. Export public functions from the app package to access methods of that object. Remove all explicit references to *app.Aerc and replace them with calls to these functions. For references to private/unexported fields and functions from within the app package, directly access the global aerc object.

* widgets: rename package to appRobin Jarry2023-10-101-6/+6
| | | | | | | | | This is the central point of all aerc. Having it named widgets is confusing. Rename it to app. It will make a cleaner transition when making the app.Aerc object available globally in the next commit.

* config: make various sections accessible via global varsRobin Jarry2022-12-141-2/+1
| | | | | | | | | | | | | | | | | | | | There is only one instance of AercConfig which is associated to the Aerc widget. Everywhere we need to access configuration options, we need somehow to get a reference either to the Aerc widget or to a pointer to the AercConfig instance. This makes the code cluttered. Remove the AercConfig structure and every place where it is referenced. Instead, declare global variables for every configuration section and access them directly from the `config` module. Since bindings and ui sections can be "contextual" (i.e. per account, per folder or per subject), leave most local references intact. Replacing them with config.{Ui,Binds}.For{Account,Folder,Subject} would make this patch even more unreadable. This is something that may be addressed in the future.
