* format: add utf-8 aware truncate head functionRobin Jarry2023-01-042-0/+27
| | | | | | | | | The runewidth module only allows truncating at the end of strings. Add a function to truncate at the beginning. It will be used for the table widget in the next commit. Signed-off-by: Robin Jarry <robin@jarry.cc> Acked-by: Tim Culverhouse <tim@timculverhouse.com>

* msgstore: fix deadlock in thread builderRobin Jarry2023-01-031-1/+5
| | | | | | | | | | | | | | | | | | When scrolling while the thread builder is running, aerc freezes. This issue can be easily reproduced by keeping the down arrow pressed while a folder is loading with local threading enabled. This is caused by the threadCallback function calling store.Select which acquires threadsMutex. However, threadCallback is already called with threadsMutex acquired, causing a deadlock. Fix the issue by adding a new selectPriv function that does not acquire the lock and call this one in threadCallback *and* store.Select. Do not reset threadCallback to nil as it was before.

* textinput: fix crash when scrolling back in command historyRobin Jarry2023-01-021-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Pressing up while in command mode, calls TextInput.Set() with the previous command in the history. If the command exceeds the current terminal width, there is a scroll mechanism that puts the cursor at the end of the text (see ensureScroll()). However, the offset used to perform the draw is not the current scroll value but the "previous" one. When the one before last command required a longer scroll offset than the current command length, this causes a crash: Error: runtime error: slice bounds out of range [348:5] git.sr.ht/~rjarry/aerc/lib/ui.(*TextInput).Draw(0xc0017ce000, 0xc005460570) git.sr.ht/~rjarry/aerc/lib/ui/textinput.go:111 +0x525 git.sr.ht/~rjarry/aerc/widgets.(*ExLine).Draw(0x30?, 0xc01de13b08?) git.sr.ht/~rjarry/aerc/widgets/exline.go:76 +0x1d git.sr.ht/~rjarry/aerc/lib/ui.(*Stack).Draw(0xc0003f0ff0?, 0x0?) git.sr.ht/~rjarry/aerc/lib/ui/stack.go:30 +0x49 git.sr.ht/~rjarry/aerc/lib/ui.(*Grid).Draw(0xc00038c240, 0xc0003f0ff0) git.sr.ht/~rjarry/aerc/lib/ui/grid.go:126 +0x225 git.sr.ht/~rjarry/aerc/widgets.(*Aerc).Draw(0xc0003f4000, 0xc0003f0ff0) git.sr.ht/~rjarry/aerc/widgets/aerc.go:176 +0x1d2 git.sr.ht/~rjarry/aerc/lib/ui.(*UI).Render(0xc0003a0000) git.sr.ht/~rjarry/aerc/lib/ui/ui.go:110 +0x63 main.main() git.sr.ht/~rjarry/aerc/aerc.go:255 +0x9c5 There are actually two distinct issues here: 1) The scroll offset used for drawing must be the current one, not the one from the previous ensureScoll() call. 2) The scroll offset must be reset when changing the text with TextInput.Set(). Other methods that change the text actually call ensureScroll but they make incremental changes to the text, since Set completely overwrites everything, it makes more sense to set the scroll offset to 0.

* threads: rebuild server threads when updating threadsTim Culverhouse2022-12-142-2/+13
| | | | | | | | | | | | | | | | | The addition of the iterator factory added a thread builder when using server side threads. A conditional for returning UIDs when selecting messages would check for a not-nil store.builder, and return UIDs from the thread builder. When using server side threads, there was no mechanism to update the threads after a message deletion or move, so store.Uids() would return a stale set of UIDs. This would allow the user to "select" a deleted email (the cursor would disappear). Add an update mechanism for the threads if server side threads are enabled. When building thread UIDs, check for deleted or hidden threads.

Through the evolution of the split logic, additional variables were stored within the account which allows for cleaner updating of the split. Compare selected UID instead of pointer to message when deciding not to update split. Allow splits to be created and closed when no message is selected. The split will be filled with a ui.Fill (blank). The user will only see a border at the split location when no message is selected. Rename clearSplit to closeSplit, as it is only used in the case when the user doesn't want a split anymore.

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.

This command takes a MIME type as argument which needs to match a setting in the new [multipart-converters] section of aerc.conf. A part can be removed by using the -d flag. The [multipart-converters] section has MIME types associated with commands. These commands are executed with sh -c every time the main email body is updated to generate each part content. The commands are expected to output valid UTF-8 text. If a command fails, an explicit error will be printed next to the part MIME type to allow users to debug their issue but the email may still be sent anyway with an empty alternative part. This is mostly intended for people who *really* need to send html messages for their boss or for corporate reasons. For now, it is a manual and explicit action to convert a message in such a way. Here is an example configuration: [multipart-converters] text/html = pandoc -f markdown -t html And the associated binding to append an HTML alternative to a message: [compose::review] H = :multipart text/html<enter> hh = :multipart -d text/html<enter> Link: https://lists.sr.ht/~rjarry/aerc-discuss/%3CCO5KH4W57XNB.2PZLR1CNFK22H%40mashenka%3E Co-authored-by: Eric McConville <emcconville@emcconville.com> Signed-off-by: Robin Jarry <robin@jarry.cc> Tested-by: Bence Ferdinandy <bence@ferdinandy.com> Acked-by: Moritz Poldrack <moritz@poldrack.dev>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I had started writing this as an awk script but quickly got stuck with obscure code which did not even work properly. I jumped the gun and re did it in go. Bonus, we will not have MacOS's 1987 BSD awk issues. On the other hand, instead of a 20.0K awk script, we now have a 2.2M static go binary. If this makes people scream, I challenge them to do that with BSD awk :) Basically, this takes text from stdin or from a file and wraps long lines on word boundaries. It takes care of not breaking up email quotes nor list items (numbered as well). Also, it is conservative by default and only wraps long lines and lines that end with a space (indicating a format=flowed message). If the AERC_SUBJECT environment variable is defined and contains the word PATCH, the text is not modified at all (i.e. wrap behaves as cat(1)). There are a few command line options to control behavior: Usage of ./wrap: -f string read from file instead of stdin -l int minimum percentage of letters in a line to be considered a paragaph (default 50) -r reflow all paragraphs even if no trailing space -w int preferred wrap margin (default 80) Update docs, makefile and default config file with examples. Add a torture test to ensure it works as expected. Signed-off-by: Robin Jarry <robin@jarry.cc> Tested-by: Bence Ferdinandy <bence@ferdinandy.com>
