* main: rename aerc.go -> main.goRobin Jarry2023-03-151-263/+0
| | | | | | | | I like it better that way. And it will not piss me off every time I need to use auto completion. Signed-off-by: Robin Jarry <robin@jarry.cc> Acked-by: Moritz Poldrack <moritz@poldrack.dev>
* ipc: use an interface instead of a function listMoritz Poldrack2023-03-071-3/+1
| | | | | | | | | Currently, every function has to be mapped to the according handler with our god-object. To make adding new handlers require less changes, change this mapping into an interface that is satisfied by *widgets.Aerc Signed-off-by: Moritz Poldrack <git@moritz.sh> Signed-off-by: Robin Jarry <robin@jarry.cc>
* ipc: change protocol to JSONMoritz Poldrack2023-03-071-8/+3
| | | | | | | | | | | | | | | | | | | | | | In overhauling the IPC, it has become necessary to switch to a more extendable message format, to ensure more complex commands can be sent. Messages have the following basic structure and must not contain linebreaks, as these are used to delimit separate messages from one another. {"arguments": ["mailto:moritz@poldrack.dev"]} The responses have the following structure: {"error": "epic fail"} If the IPC request was successful, "error" will be empty. {"error": ""} Signed-off-by: Moritz Poldrack <git@moritz.sh> Signed-off-by: Robin Jarry <robin@jarry.cc>
* socket: extract functionality into ipc packageMoritz Poldrack2023-03-071-4/+4
| | | | | | | | | | | | The current model of files dumped into lib does not follow the general advice not to have "util" classes. Naming the package "lib" does not change that it is a random assortments of functions that have some utility. Extracts socket functionality into it's own package.

* lint: always run golangci-lint@latestRobin Jarry2023-02-261-2/+4
| | | | | | | | | | | | Do not store the dependency in tools.go as there may be conflicts with some indirect dependencies of aerc. Run gofumpt and golangci-lint from their latest tagged release. This should fix issues with go 1.20. Bonus, it drains a bit of fat from go.sum. Signed-off-by: Robin Jarry <robin@jarry.cc> Acked-by: Moritz Poldrack <moritz@poldrack.dev>
* triggers: use templates instead of % mini languageRobin Jarry2023-02-201-4/+11
| | | | | | | | | | | | | | | | | | | | | Since previous commit, all commands now support expanding text/template markup. Reuse that for the new-email trigger command. Update commands.ExecuteCommand to take optional *AccountConfig and *MessageInfo arguments. If these are nil, fallback to using the currently selected account and message (if any). Pass the proper *AccountConfig and *MessageInfo objects when firing the trigger command so that these are used instead of the currently selected ones. If new-email contains % placeholders, try to convert them to template markup reusing the same conversion added in commit 535300cfdbfc ("config: add columns based index format"). Warn the user that they need to update their configuration file. Signed-off-by: Robin Jarry <robin@jarry.cc> Reviewed-by: Moritz Poldrack <moritz@poldrack.dev>
* config: make various sections accessible via global varsRobin Jarry2022-12-141-4/+4
| | | | | | | | | | | | | | | | | | | | 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.

* logging: rename package to logRobin Jarry2022-12-021-14/+14
| | | | | | | | | | Use the same name than the builtin "log" package. That way, we do not risk logging in the wrong place.

* logging: homogenize levelsRobin Jarry2022-12-021-2/+2
| | | | | | | | | | | | | | | | | | The main goal is to ensure that by default, the log file (if configured) does not grow out of proportions. Most of the logging messages in aerc are actually for debugging and/or trace purposes. Define clear rules for logging levels. Enforce these rules everywhere. After this patch, here is what the log file looks like after starting up with a single account: INFO 2022/11/24 20:26:16.147164 aerc.go:176: Starting up version 0.13.0-100-g683981479c60 (go1.18.7 amd64 linux) INFO 2022/11/24 20:26:17.546448 account.go:254: [work] connected.

* aercmsg: add AercFuncMsg and QueueFuncTim Culverhouse2022-10-181-0/+2
| | | | | | | | | | Introduce AercFuncMsg and QueueFunc. These are used in combination to queue a function to be run in the main goroutine. This can be used to prevent data races in delayed function calls (ie from debounce functions). Signed-off-by: Tim Culverhouse <tim@timculverhouse.com> Acked-by: Robin Jarry <robin@jarry.cc>

* ui: cleanup internals and apiRobin Jarry2022-09-141-2/+2
| | | | | | | | | | | | | | | | Now that tcell events are handled in a goroutine, no need for a channel to buffer them. Rename ui.Tick() to ui.Render() and ui.Run() to ui.ProcessEvents() to better reflect what these functions do. Move screen.PollEvent() into ui.ProcessEvents(). Register the panic handler in ui.ProcessEvents(). Remove aerc.ui.Tick() from DecryptKeys(). What the hell was that?

* ui: process tcell events in a separate go routine from renderingTim Culverhouse2022-09-131-0/+1
| | | | | | | | | | | | | The UI runs off a 16 ms ticker. If no render is required, and no event is seen, aerc waits 16 ms before checking for new events or render requests. This severely limits handling of events from tcell, and is particularly noticeable on pasting of large quantities of text. Process tcell events in a separate go routine from the render loop.

| | | | | | | | | | | | | | | | | Use Aerc as an mbox viewer. Open an mbox file from the command line in a new tab with the mbox backend. Provide a convenient and quick way to display emails from an mbox. Usage: aerc mbox://<path> where the path can either be a directory or an mbox file. If it is a directory, every file with an .mbox suffix will be loaded as a folder. The account config will be copied from the selected account. This allows the answer emails in the mbox account.

* logging: fix race condition in startupMoritz Poldrack2022-03-241-1/+4
| | | | | | | | | If a panic occurs in one of the workers, it can happen after the UI was initialised, but before the cleanup function has been registered. With this the start of the worker loops is deferred until the cleanup routine was registered. Signed-off-by: Moritz Poldrack <git@moritz.sh>
* logging: added a log on panicMoritz Poldrack2022-03-231-19/+5
| | | | | | | | | | | | | Since panics still regularly "destroy" the terminal, it is hard to get a stack trace for panics you do not anticipate. This commit adds a panic handler that automatically creates a logfile inside the current working directory. It has to be added to every goroutine that is started and will repair the terminal on a panic. Signed-off-by: Moritz Poldrack <git@moritz.sh> Acked-by: Robin Jarry <robin@jarry.cc>

| | | | | | | | | | | | Instead of using a static SHAREDIR at compile time, use a list of standard paths to use at runtime for templates, config files and stylesets.

* aerc: shutdown if socket communication failsAdnan Maolood2022-01-241-10/+13
| | | | | | | | | When provided with a mailto argument, aerc tries to connect to an existing instance via a unix socket. If that fails, it starts up a new instance and tries again. However, if that fails again (e.g. if the unix server could not be started) then the new instance will remain open without any indication that an error occured. Instead, shutdown the new instance so the user can see the error message.

| | | | | | | | | After commit 175d0ef ("binds: add account specific bindings"), when bindings are defined for an account not defined in accounts.conf, aerc quits with an error. After this commit, a warning is logged and aerc ignores those bindings. Signed-off-by: inwit <inwit@sindominio.net>

* aerc: try to recover from a panicReto Brunner2021-02-111-0/+19
| | | | | | As of now we crash fairly often. The problem is that we didn't run the cleanup routine of the ui in this case, leaving the pty in a bad state. Instead, recover from a panic and at least try to run the ui deinit.
* Sort command completionsJeffas2020-06-131-0/+2
| | | | | | Previously the completions weren't sorted which led to a difficult to navigate list, especially for the command names as it would randomly jump through the alphabet.

* Don't use current input as a possible completionBen Burwell2019-12-211-1/+0
| | | | | Now that completions are being shown in the popover, it doesn't make sense to show the unfinished command as a potential completion.
* Open mailto links in a new aerc instance if needed.Reto Brunner2019-09-291-2/+17
| | | | | | | | | | | | | Aerc tries to open mailto:// links via the socket of the already running aerc instance. If no socket exists this silently errored out. This commit starts up a new aerc instance if it can't connect to the socket (which I think is the most common error) and if not sets up a new aerc instance and retries to open the compositor. This fixes https://todo.sr.ht/~sircmpwn/aerc2/295 by implementing the desired behaviour.
* Add initial command to end of completionsJeffas2019-09-111-0/+1
| | | | | This means that if the user cycles through all completions then they will see the initial string they entered.

* Close backends prior to shutdownReto Brunner2019-08-081-0/+1
| | | | | | | We need some way to signal the backends that we are about to shutdown, allowing them to clean up (for example in notmuch committing the db changes). This commit implements a hook which gets called upon shutdown, providing backends implement the io.Closer interface.
* Remove aerc specific code from the uiNicolai Dagestad2019-08-031-1/+5
| | | | | Separatiing the ui code from aerc makes it usable as a library in other projects.
* Print errors from config load issues.Reto Brunner2019-07-291-1/+1
| | | | | | Currently we /dev/null stdout, if it is a tty. The checkConfigPerms function, as well as the error print were incorrectly writing to stdout and therefore weren't visible to most users.
* Add command history and cyclingGalen Abell2019-07-261-1/+1
| | | | | | Aerc will keep track of the previous 1000 commands, which the user can cycle through using the arrow keys while in the ex-line. Pressing up will move backwards in history while pressing down will move forward.
* Add new-email triggerJeffas2019-07-261-6/+6
| | | | | | | | | | | | | | | | | This patch sets up the trigger config section of aerc.conf. Each trigger has its own function which is called from the place where it is triggered. Currently only the new-email trigger is implemented. The triggers make use of format strings. For instance, in the new-email trigger this allows the user to select the trigger command and also the information extracted from the command and placed into their command. To actually execute the trigger commands the keypresses are simulated. Further triggers can be implemented in the future. Formatting of the command is moved to a new package.
* Discard stdout if not redirected to fileDaniel Bridges2019-07-231-0/+1
