# krino-gui: the checklist before a release
The GTK layer has no automated tests (gui-design.md §6): package
`gui/internal/model` is tested, `gui/internal/ui` is not. This list is run
by hand before every release that changes the GUI, and what it found goes
in the release's plan record.
Run it against a sandbox, never a real directory:
```sh
S=$(mktemp -d)
mkdir -p "$S/home/.config/krino/dirs" "$S/inbox"
HOME="$S/home" XDG_CONFIG_HOME="$S/home/.config" XDG_DATA_HOME="$S/home/.local/share" \
XDG_STATE_HOME="$S/home/.local/state" XDG_CACHE_HOME="$S/home/.cache" krino init
# write dirs/inbox.conf with (path "$S/inbox") and a few rules, put
# invented files in "$S/inbox", then run krino-gui with the same HOME and
# XDG_* set.
```
A headless X server keeps the run out of the way of whatever else is on the
screen, and lets `import` take the same screenshots:
```sh
Xvfb :99 -screen 0 1280x800x24 &
DISPLAY=:99 krino-gui &
DISPLAY=:99 import -window "$(DISPLAY=:99 xdotool search --name '^krino$' | tail -1)" shot.png
```
A dialog is its own window: take it by its own id, not the main window's.
## Plan tab
1. The directory picker lists every included directory, and the path beside
it is the one the file names.
2. Scan plans it; the counts line reads like `krino -n`'s: scanned, to act
on, excluded, skipped, with warnings.
3. Each row shows the file, what would happen and where, and the rule. A
file krino could not decide about is listed and cannot be checked.
4. Select all, None, and the Apply button's count agree with the boxes.
5. Selecting a row explains it: every step, its rule and reason, and any
warning.
6. Right-clicking a row offers Trash instead and Delete permanently
instead. The second asks first, names the file, and Escape leaves the
plan as it was.
7. Apply acts on the checked files only: each row shows done, failed with
the reason, or declined, and the status bar summarises.
8. While a plan is open, `krino -n` on that directory waits for the lock;
after Apply, or after closing the window, it proceeds.
## History and undo tab
9. Runs are newest first, with time, directory and counts; a reversed run
says `(undone)`.
10. Selecting a run shows its reversal: the header counts, one row per
file, refused rows in red and not checkable.
11. Undo reverses the checked files, logs the rest as declined, and the run
list then shows the undo run and marks the original.
12. Selecting an undo run offers what is left of the run it reversed, as
plain `krino undo` does.
## Rules tab
13. Forms lists the directory itself, then the excludes and rules with
their actions.
14. Selecting a rule fills its form: name, conditions, actions, `(stop)`,
settings.
15. Changing a field rewrites only that form - check on the Text sub-tab
that every comment and every other rule is untouched.
16. Add rule inserts after the selected rule and the check stays clean;
Delete asks first and takes the comment lines above the rule; Up and
Down move a rule with those comments.
17. The directory's settings form writes into the header, above the rules,
and an empty field takes the setting out of the file.
18. A form with comments inside it warns before an edit drops them and
offers the Text tab.
19. Text: a mistake appears within a second as `file:line:col` in red, Save
greys out, and clicking the message goes to the line.
20. Test on file prints the trace, the captures and the chain, answering
from the unsaved text.
21. Save writes the file, leaves the previous text as `NAME.conf.bak`, and
the Plan tab then plans with the new rules.
22. With the file changed underneath (edit it in another program), Save
offers Reload, Overwrite and Cancel; Overwrite keeps the other text as
the backup.
## Window
23. Nothing on disk changes until Apply, Undo or Save.
24. Closing the window releases the directory lock it held.
25. A configuration that does not load prints the problem and exits 2
rather than opening a window.
## Settings and preview
26. Selecting a row in the Plan tab shows the file under its explanation: a
picture for an image, the rendered first page for a PDF, the first
lines for text, and a plain note for anything else.
27. Settings writes krino's defaults into `krino.conf` - refused while the
configuration would not load, previous text kept as `krino.conf.bak` -
and the tabs work from the new defaults at once.
28. The window preferences take effect as they are changed (font size,
preview height, colours, preview, a plan starting unchecked) and
survive a restart.
29. Dragging the divider above the preview resizes it, the size is still
there after a restart, and a PDF page is rendered large enough to suit
it rather than magnified.
30. The filter box narrows the plan as it is typed, `Select all` then
checks only what is shown, and the status line says how many checked
files are hidden.
31. `With checked` sets every checked file to Trash, or - after a
confirmation naming the count - to a permanent delete; the rows change
and nothing moves until Apply.
32. Closing the window with files checked and nothing applied asks first.
33. Every setting in Settings explains itself when the pointer rests on it.
34. The columns line up with their headings, whatever the file names are.
35. The layout setting switches between the file list beside the
explanation and the file list on top with the preview beside it, and
the choice survives a restart.
36. "after a scan" decides whether a fresh plan starts checked or not.
37. The action colours follow the GTK theme: they are its accent, warning
and error colours, not a palette of krino's own.
38. Once a plan has been applied its checkboxes, Select all, None and With
checked are all off, and the status line says to press Scan for a fresh
plan - an applied plan is history, not a list to keep working from.
39. In Settings, the window half needs no saving and says so; Save
krino.conf is lit only when the defaults above it have changed.
40. Both dividers stay where they are dragged, per layout, across a
restart, and a list narrower than its columns still starts at the file
names rather than scrolled past them.
41. Size and age read in krino's own units, and each of size, age and rule
can be turned off in Settings.
42. A selected row's action stays readable: it takes the row's own
foreground rather than keeping its colour on the selection background.
43. The explanation beside the list is centred: the file's name, its size
and age, then a line per step with the action coloured.
