# Changelog

All notable changes to this project are documented here.

The format follows [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

While the version is below 1.0.0, the configuration file format and the
keybinding action names may change in a minor release. 1.0.0 will mark the
point at which they are stable.

## [Unreleased]

### Added

- **`assets/mailsync.sh`**, the reference sync command, moved here from the
  companion `mailctl` project. It never belonged there: `mailctl` does not call
  it, while qtmaildir runs it as a subprocess and depends on how it behaves.
  Symlink it into `~/bin` rather than copying, so one script serves both cron
  and the application.

### Fixed

- **The sync log pane stayed empty**, listed as a known limitation since 0.1.0.
  The reference `mailsync.sh` redirected all its output to a log file, so the
  subprocess printed nothing for the pane to show. It now writes to both.
- **A failed sync reported success.** That script ended in an unconditional
  `exit 0`, so qtmaildir could not tell a clean sync from a broken one: it
  cleared the unsynced-changes count either way, and would have quit on a
  sync-on-exit that had not synced anything. It now exits with the real status.

## [0.7.0] - 2026-08-04

Tagging stops being limited to the five tags someone chose in advance, and the
application admits when your work has not reached the mail store yet.

### Added

- **An Edit tags dialog**, on **Ctrl+T** or Message > Edit tags. Type tags to
  add or remove, separated by commas, or clear a checkbox to drop a tag already
  on the selection without retyping it. Until now archive, delete, spam, flag
  and toggle-unread were the only tags reachable from the UI, and applying any
  other one meant leaving for a terminal.
- Both fields **complete against every tag in the database**, matching on
  substrings so `amazon` finds `shopping/amazon`. Completion is a guard against
  typing `shoppping` beside `shopping`, not a restriction: a tag that does not
  exist yet is exactly what the dialog is for.
- With several threads selected, a tag on only some of them shows a partially
  checked box saying how many. **Leaving it alone changes nothing.** Check it to
  apply to all, clear it to remove from all.
- Tag names are refused if empty, if they start with `-` (notmuch reads that as
  "remove this tag", so such a tag is a trap), or if they contain spaces or
  unprintable characters. Nothing is applied until the whole set is valid, since
  a half-applied change leaves you unable to tell which half landed.
- **The status bar counts tag changes a sync has not carried over**, and clears
  the count when one succeeds. A failed sync leaves it standing.
- **Quitting with changes outstanding asks what to do**, via the new
  `[general] sync_on_exit`: `ask` (the default) offers to sync, quit anyway or
  stay; `always` syncs without asking; `never` quits silently. A sync started at
  exit holds the window open until it finishes rather than being killed
  mid-run, and one that fails does not quit.

### Fixed

- In the tag fields, only the first tag completed. `QLineEdit::setCompleter`
  matches against the widget's entire text, so once a field read `unread, fl`
  that whole string was matched against the tag names and nothing was offered
  again. The same defect the query bar hit in 0.5.0, in a second place.

### Notes

The unsynced count is a lower bound rather than a guarantee: an external
`notmuch new` from your own cron can carry changes over without the application
noticing.

The exit prompt is not a destructive-action confirmation of the kind this
project avoids. Those cover tag mutations, which keep undo instead of a dialog.
This asks about losing work at the one point where undo cannot help.

## [0.6.0] - 2026-08-04

Two things the app knew and would not say: who a message was addressed to,
and whether you had read it.

### Added

- **From, To and Cc in the message header.** All three were parsed on every
  message and then discarded before rendering. A thread holding one message
  now shows them under the subject.
- A thread holding **several** messages still shows only the subject and the
  count. From, To and Cc differ per message, and once you have replied there is
  no single address the thread is addressed to, so naming one would be a guess
  presented as a fact. An empty Cc omits its row rather than printing a label
  with nothing after it.
- **A details dialog**, behind a `Details...` button beside the subject or
  `Ctrl+Shift+D`, listing Subject, From, To, Cc, Date and Message-Id for every
  message in the thread, numbered. Read-only plain text: these values come from
  strangers, and the format that cannot interpret markup is the right one for
  showing them verbatim.
- **An opened thread is marked read after a delay**, 2 seconds by default.
  Arrowing quickly through a list marks only the thread you stop on, never the
  ones you pass through. Configurable through `[general] mark_read_delay_ms`:
  zero marks read at once, and any negative value turns the behaviour off.

### Notes

The automatic mark-read is deliberately **not** on the undo stack. Undoing an
action you never took is worse than leaving a thread read, and `Ctrl+U` already
puts it back. Marking a thread unread by hand cancels any pending timer, so the
key cannot be silently reversed a moment later.

**HTML messages already opened as HTML**, which a backlog item had doubted.
Verified against real mail; no code changed. No preference was added for
defaulting to plain text, since `Ctrl+H` already switches a thread by hand.

## [0.5.0] - 2026-08-04

Completion in the query bar. The point is not to save typing but to make the
notmuch query language discoverable: every candidate carries a description, so
the bar teaches the syntax to someone who has never written a notmuch query.

### Added

- **Query prefixes** complete with a description each: `tag:`, `is:`, `from:`,
  `to:`, `subject:`, `date:`, `attachment:`, `mimetype:`, `folder:`, `path:`,
  `thread:`, `id:`, and the `and` / `or` / `not` operators. The list is
  hardcoded, since notmuch exposes no way to enumerate its own prefixes.
- **Tag names** after `tag:` and `is:`, which notmuch treats as synonyms. The
  list is the real set of tags in the database, refreshed at startup, after a
  sync, and whenever a tag mutation introduces one that was not there before.
- **Dates** after `date:`, symbolic and relative, completing each bound of a
  `..` range independently. Entries that are themselves open-ended ranges,
  like `1week..`, are withheld once a range is already underway, since they
  would produce malformed queries inside one.
- **Content types** after `mimetype:`, from a built-in list extensible through
  the new `[completion] extra_mimetypes` key. Entries are appended to the
  built-ins rather than replacing them, so a typo cannot leave you with fewer
  completions than the defaults.
- **Account directories** after `path:`, in both the plain and the recursive
  `<maildir>/**` form.
- `complete_query`, bound to **Ctrl+Space**, opens the popup on demand.
- `[general] completion_on_focus`, off by default, opens it as soon as an empty
  query bar takes focus.
- Accepting a prefix chains straight into its values, so taking `tag:` offers
  the tag list without a second keystroke.

### Fixed

- Return in the query bar ran nothing and moved focus to the thread list.
  Return is bound to `open_thread` as a window shortcut, and a shortcut is
  dispatched before the focused widget sees the key; Qt withholds plain-letter
  shortcuts from editable widgets, but Return is not a letter and got no such
  protection. The query bar now claims the key back while it has focus.
- Tab and the arrow keys crashed the application outright while the popup was
  open. `QCoreApplication::sendEvent` re-runs application-level event filters,
  so the filter forwarding a key to the popup was handed the same key straight
  back, recursing until the stack was exhausted.

### Notes

The example configuration in the README had two keys that were live rather
than commented, so copying the block activated a sync command and three
mimetypes the reader never chose. Both are commented now.

`from:` and `to:` complete no addresses: libnotmuch exposes no call to
enumerate them. `folder:` completes nothing either, as a Maildir folder name
is not something the configuration can enumerate. Saved query names are
deliberately absent, a name not being valid notmuch syntax.

## [0.4.1] - 2026-08-03

Packaging only. No change to the application itself.

### Added

- A SlackBuild under `assets/slackbuild/`, with the usual `.info`,
  `slack-desc`, `doinst.sh` and `README`. It follows SBo conventions except
  for the tag, `_danix` rather than `_SBo`, and the package type, `txz` rather
  than `tgz`, since it is not an SBo submission.
- `QTMAILDIR_BUILD_TESTS`, on by default. Turning it off skips the test suite
  and its `Qt6::Test` dependency, which a packaging build has no use for.
  0.4.0 accepted this flag but ignored it, because the option did not exist in
  that tarball; this release is the first where it takes effect.

## [0.4.0] - 2026-08-03

Attachments become reachable. They were parsed all along and there was simply
no way to get at one, and no way to tell a message had any without opening it.

### Added

- A paperclip column marks threads carrying an attachment, so it is visible
  without opening the thread. Driven by the `attachment` tag notmuch already
  applies, so it costs no extra query.
- The message pane lists attachments behind one **Attachments (N)** button:
  a dialog with the message number, filename and size, a **Save** for each,
  and **Save all** when there is more than one.
- **Save all** writes into a new subfolder named `<date> <subject>` inside a
  folder you pick, so a thread with sixteen files does not scatter them among
  whatever is already there. The folder is named in the picker before you
  choose, and an existing folder of that name is never merged into.

### Fixed

- **Attachments were unreachable.** The attachment bar had been created and
  added to the layout since it was written, and nothing ever populated it.
- **Saving several attachments could destroy files.** Messages in one thread
  commonly attach the same filename, and each save overwrote the previous one
  while still reporting success: sixteen attachments produced ten files. Batch
  saves now add a numeric suffix instead, and keep a compound extension like
  `.tar.gz` whole.
- **A `Date:` header carrying a timezone comment lost its date.** `+0200
  (CEST)` is legal and common, but Qt rejects the whole header rather than the
  comment, so those messages got no date prefix on their folder.

### Changed

- Thread-list column widths reset once on first launch after upgrading. The
  saved layout is from before the paperclip column existed, and applying it
  would have shifted every width onto the wrong column.

## [0.3.0] - 2026-08-03

The app remembers how you left it. Window, splitter and column sizes survive
a restart, the message pane owns its zoom and keeps it, and startup opens the
query you asked for rather than whichever one sorted first.

### Added

- Window geometry, splitter position and thread-list column widths persist
  across restarts. Machine-written state lives in a separate file,
  `~/.local/state/qtmaildir/uistate.conf`, and never touches the hand-edited
  config: a base64 geometry blob does not belong in a file you edit, and
  rewriting that file on exit would drop its comments and key order.
- The message pane owns its zoom, which is remembered across restarts. It was
  previously the web engine's own behavior, invisible to the application,
  which is why there was nothing to save.

  | Gesture | Does |
  |---|---|
  | `Ctrl++` | Zoom in |
  | `Ctrl+-` | Zoom out |
  | `Ctrl+0`, `Ctrl+=` | Actual size |
  | `Ctrl`+wheel | Zoom in and out |
  | `Ctrl`+middle-click | Actual size |

  All three actions appear in the View menu and are rebindable through
  `[keys]` as `zoom_in`, `zoom_out` and `zoom_reset`. The factor is clamped
  to 0.5 - 3.0.
- `[general] message_zoom` sets the starting zoom for a profile that has
  never zoomed. Once you zoom, the state file remembers that instead.
- `[general] startup_query` names the saved query to open at startup, and
  defaults to `Unread`.

### Changed

- **Startup no longer opens `savedQueries().first()`.** `[queries]` is read
  through `childKeys()`, which sorts alphabetically, so the query that opened
  was whichever name sorted first rather than one you chose. It is now
  selected by name. If your `[queries]` has no entry named `Unread`, set
  `[general] startup_query` to the one you want, or you will keep getting the
  alphabetically first one. Saved-query button order is unchanged.

### Fixed

- **`[general]` keys were never read.** They were looked up as
  `general/<key>`, which matches nothing: QSettings' INI backend treats a
  section literally named `[general]` as its own fallback section and strips
  the prefix. `notmuch_config` had therefore been silently ignored since it
  was introduced. If you set it and wondered why nothing changed, it works
  now. The file format is unchanged.

## [0.2.0] - 2026-08-03

Menus, a toolbar and an in-app shortcut reference, so the app is usable
without memorizing keys. Tags render as coloured chips rather than a column
of text. Three default keybindings that had never worked now do.

### Added

- Tags render as coloured chips instead of text in a column. The account tag
  sits in front of the subject in the thread list, and the functional tags fill
  a single row under the message pane, with anything that does not fit
  collapsing into a `+N` chip whose tooltip names the rest.
- `[tagcolors]` config group. Colours resolve by exact tag first, then by
  top-level prefix, so one `shopping` entry covers `shopping/amazon` and
  `shopping/nike` while `shopping/amazon` can still override its own. Built-in
  defaults cover the usual state tags; anything unconfigured gets a stable
  colour derived from its name.
- `color` and `label` keys in an account stanza, setting the account chip's
  fill and its text. `label` shortens a long key for display only and renames
  nothing in notmuch; unset falls back to the key.
- The application icon is now used: window icon, a `.desktop` entry, and
  install rules placing both into `hicolor` and `share/applications`.
- Toolbar and menu actions carry icons from the system theme, falling back to
  text where a theme lacks one.
- Menu bar covering every action: File, Edit, Message, View and Help.
- Toolbar with the frequent subset, Sync, Archive, Delete and Undo.
- **Help > Keyboard shortcuts**, listing the current bindings. Generated from
  the actions themselves, so it shows configured overrides rather than a
  hand-written copy of the defaults.
- **Help > About**.
- Default bindings for `spam` and `load_remote`, which previously had none
  and were unreachable until bound by hand.

### Fixed

- Acting on a thread now visibly changes its row. A thread tagged `deleted`
  or `spam` is filled dark red or orange, in white struck-through text, across
  every column. The tag change was already applied, but `Tags` sat after the
  stretching `Subject` column and was pushed off-screen, so Delete looked like
  it had done nothing.
- Thread list columns are Date, From and Subject, all resizable. The tags
  column is gone: spelling out a dozen tags per row consumed most of the list's
  width. Widening past the viewport scrolls horizontally rather than squeezing
  the other columns.
- Hierarchical tags in `[tagcolors]` were silently ignored. QSettings treats
  `/` in a key as a group separator, so `shopping/amazon` becomes a nested key
  that `childKeys()` never returns, and every tag containing a `/` fell through
  to its prefix.
- Three default bindings never fired. Typing a capital sends `Shift`+the key,
  but `N`, `F` and `G` were stored as the unshifted key, which no keystroke
  produces, leaving `toggle_unread`, `flag` and `sync` dead. A bare capital in
  `[keys]` is now read as `Shift`+that letter. As a side effect `y` and `Y`
  are two distinct keys rather than a collision that silently dropped one.
- Modifier shortcuts such as `Ctrl+Q` now work while the query bar has focus.
  The old event filter suppressed every binding there, not only the plain
  letters that would have interfered with typing.

### Changed

- Default bindings moved to modifier shortcuts. **A `[keys]` section written
  for 0.1.0 keeps working and keeps the old keys**, which also means it hides
  every new default: delete the section to adopt them, or rebind individually.
  Single letters are still safe to bind, since Qt suppresses a plain-letter
  shortcut while the query bar has focus.

  | Action | 0.1.0 | 0.2.0 |
  |---|---|---|
  | `next_thread` | `j` | `Ctrl+J` |
  | `prev_thread` | `k` | `Ctrl+K` |
  | `open_thread` | `Return` | `Return` |
  | `archive` | `a` | `Ctrl+E` |
  | `delete` | `d` | `Ctrl+D` |
  | `spam` | *(unbound)* | `Ctrl+Shift+S` |
  | `toggle_unread` | `N` *(never fired)* | `Ctrl+U` |
  | `flag` | `F` *(never fired)* | `Ctrl+I` |
  | `focus_query` | `/` | `Ctrl+L` |
  | `toggle_html` | `h` | `Ctrl+H` |
  | `load_remote` | *(unbound)* | `Ctrl+M` |
  | `undo` | `u` | `Ctrl+Z` |
  | `sync` | `G` *(never fired)* | `Ctrl+G` |
  | `quit` | `Ctrl+Q` | `Ctrl+Q` |

  Action names are unchanged, so no existing binding becomes invalid.
- Actions are `QAction`s dispatched by shortcut rather than a hash of
  callbacks behind an event filter, which is what lets them appear in menus.
  The hand-maintained list of registered action names is now derived from the
  actions, so it can no longer drift from them.

## [0.1.0] - 2026-08-03

First release. Reads and organizes a local notmuch-indexed Maildir; it does
no network protocol work at all, since fetching and sending are left to
external commands.

### Added

- Permanent notmuch query bar with saved-query buttons and per-account
  scoping, over a two-pane thread list and message view.
- Threads streamed from the database in batches of 200, so a query over tens
  of thousands of threads paints its first rows immediately and fills in
  behind. Measured at 21 ms to the first batch against a 36,000-thread
  database.
- Whole-thread rendering: every message in a thread renders into one
  document, oldest first, with messages that did not match the current query
  collapsed to one-line stubs. The last message always renders expanded, so
  a thread is never nothing but stubs.
- HTML mail rendered through QtWebEngine, with a locked-down profile:
  off-the-record, no cookies, no cache, JavaScript disabled, and a
  deny-by-default request interceptor. Remote content is blocked until the
  user asks for it, which defeats tracking pixels and read receipts; the
  grant applies to one render and is never remembered.
- Inline `cid:` images served from an in-memory map scoped to the displayed
  thread. References are namespaced per message, so two newsletters sharing
  a Content-ID do not resolve to each other's images.
- Attachment handling that treats MIME filenames as untrusted: names are
  reduced to a basename and refused if the resolved path escapes the chosen
  directory.
- Tagging (archive, delete, spam, flag, read/unread, custom) over a
  multi-thread selection, applied optimistically and reverted if the write
  fails. Thread ids are resolved to message ids in a single combined query
  rather than one query per thread.
- Undo for tag changes, backed by a `QUndoStack`. Entries store thread ids
  and re-resolve them, so undo stays correct after the selection moves on.
  There is deliberately no dry-run and no destructive-action confirmation:
  undo is the better answer for a human at a GUI.
- Sync by running the user's existing script through `QProcess`, joining the
  `flock` that already serializes it against cron rather than reimplementing
  mbsync orchestration.
- Configurable keybindings via the `[keys]` section, validated against a
  known action list so a typo warns instead of binding silently.
- `--version` and `--help`.

### Known limitations

- Compose and send are not implemented; they are planned for v2 and need a
  companion send script that does not exist yet.
- A thread renders as a flat chronological list. Reply structure is
  available from notmuch but is not drawn as an indented tree.
- MIME parsing happens on the UI thread. Opening a very long thread parses
  every message in it, which could stutter; deferred until measured.
- The sync log pane shows what the sync command writes to stdout and stderr.
  A script that redirects its own output to a file will leave the pane
  empty.
