.Dt KRINO-GUI 1
.Os
.Sh NAME
.Nm krino-gui
.Nd review, undo and edit krino's rules in a window
.Sh SYNOPSIS
.Nm
.Op Fl c Ar file
.Op Fl version
.Sh DESCRIPTION
.Nm
is a GTK 4 window onto the same engine
.Xr krino 1
uses: it plans a directory, shows what would happen to each file, applies
what you choose, undoes a run, and edits a directory's rules. Every
decision - what matches, what is excluded, where a file lands, what may be
deleted - is the engine's, so the window and the command line always agree.
.Pp
It is a separate program from
.Xr krino 1 ,
built and installed separately
.Pq Cm make gui , Cm make install-gui ,
because it needs GTK 4 and cgo, which the command line does not.
.Pp
The options are:
.Bl -tag -width Ds
.It Fl c Ar file
Use
.Ar file
instead of
.Pa ~/.config/krino/krino.conf .
.It Fl version
Print the version and exit.
.El
.Pp
A configuration that does not load is reported the way
.Xr krino 1
reports it, and no window opens.
.Ss Plan
Pick one of the directories
.Pa krino.conf
includes and press
.Cm Scan .
Scanning takes that directory's lock, which is held while the plan is
shown, so nothing moves underneath it; a directory another krino is working
in is reported rather than waited for. Each row is a file, what would
happen to it and where, and the rule that decided. A file krino could not
decide about - unreadable content, a failed duplicate check - is listed with
the reason and cannot be selected.
.Pp
Selecting a row explains it: every step with its rule and reason, and any
warning. The right button offers
.Cm Trash instead
and
.Cm Delete permanently instead ,
the second only after a confirmation naming the file, as the
.Cm t
and
.Cm d
keys do in the terminal review.
.Pp
.Cm Apply
acts on the checked files and logs the rest as declined, exactly as
approving file by file in the terminal does. The run is written to the log
under its own run id, so
.Xr krino 1
can list and undo it.
.Ss History and undo
The runs, newest first, with what each did and whether it has been undone.
Selecting one shows its reversal: a row per file, refused files with the
reason and never checkable, and the counts. Undoing takes the locks of
every directory involved, reverses the checked files, and logs the rest as
declined. Selecting an undo run offers what is left of the run it reversed,
as plain
.Cm krino undo
does.
.Ss Rules
Only a directory's own file,
.Pa dirs/NAME.conf ,
is edited;
.Pa krino.conf
is not.
.Pp
.Cm Forms
lists the directory itself, its excludes and its rules. A rule's form holds
its name, its conditions, its actions in order,
.Ic (stop) ,
and the three rule settings; the directory's form holds the settings
.Xr krino.conf 5
documents, an empty field meaning krino's default. A condition is its kind
and its arguments as the file writes them, so no test is out of reach and
none is silently rewritten.
.Cm Add rule
inserts after the selected rule,
.Cm Delete
asks first, and
.Cm Up
and
.Cm Down
move a rule with the comment lines directly above it.
.Pp
.Cm Text
is the whole file. Either way the configuration is checked as it is edited,
about a second after typing stops: problems are listed with
.Ar file : Ns Ar line : Ns Ar column ,
and clicking one goes to that line.
.Cm Test on file
answers what the unsaved rules would do to one file, with the trace, the
captures and the chain.
.Pp
.Cm Save
is refused while the check reports anything, so a window cannot leave krino
unable to run. It writes atomically, keeps what was there as
.Pa NAME.conf.bak ,
and, if the file changed on disk since it was opened, offers to reload,
overwrite or cancel. Nothing on disk changes until Apply, Undo or Save.
.Sh FILES
.Bl -tag -width Ds
.It Pa ~/.config/krino/krino.conf
The main configuration, as for
.Xr krino 1 .
.It Pa ~/.config/krino/dirs/NAME.conf
A directory's rules, and what the Rules tab edits.
.It Pa ~/.config/krino/dirs/NAME.conf.bak
The text a save replaced.
.El
.Sh EXIT STATUS
.Ex -std
It exits 2 when the configuration does not load.
.Sh SEE ALSO

.Xr krino.conf 5
.Sh AUTHORS
krino is free software under the GPL, version 3 or later.
