.TH JAFM 1 2026-09-03 "jafm 0.1.0" "General Commands Manual"
.SH NAME
jafm \- just a fucking manual: find a symbol across every man page and open it
.SH SYNOPSIS
.B jafm
.RB [ \-1 ]
.RB [ \-l ]
.RB [ \-e ]
.RB [ \-t
.IR type ]
.RB [ \-j
.IR threads ]
.I symbol
.br
.B jafm
.RB [ \-v | \-h ]
.SH DESCRIPTION
.B jafm
greps every man page in your
.B manpath
for
.IR symbol ,
ranks the hits so the page that actually documents it floats to the top, and
drops you into an interactive picker with a live preview. Pick one and it opens
in
.BR man (1).
.PP
It exists because
.B "man <symbol>"
gives up the moment the thing you want lives inside some other page.
.BR sockaddr_in ,
for example, is documented inside
.BR inet (4).
jafm just reads all of them and finds it.
.PP
When standard input is not a terminal (say, a pipe), jafm skips the interactive
UI: it prints the numbered matches and reads a selection number from stdin.
.SH OPTIONS
.TP
.BR \-1 ", " \-\-first
Open the best (top\-ranked) match immediately, without the picker.
.TP
.BR \-l ", " \-\-list
Print the matches and exit. Opens nothing.
.TP
.BR \-e ", " \-\-exact
Match
.I symbol
as a whole word only, so
.B sockaddr
no longer drags in
.BR sockaddr_in .
.TP
.BR \-t ", " \-\-type " " \fIkind\fR
Only show pages where the symbol appears as
.IR kind :
one of
.BR struct ", " union ", " enum ", " typedef ", or " function .
.TP
.BR \-j ", " \-\-jobs " " \fIn\fR
Scan with
.I n
worker threads (default 8, capped at 64).
.TP
.BR \-v ", " \-\-version
Print version and exit.
.TP
.BR \-h ", " \-\-help
Print a usage summary and exit.
.SH KEYS
Inside the picker:
.TP
.BR \(ua ", " \(da ", " k ", " j
Move the selection.
.TP
.B Enter
Open the highlighted page in
.BR man (1).
.TP
.BR q ", Ctrl-C"
Quit without opening anything.
.SH RANKING
Matches are scored by where the symbol shows up, best first: its filename, then
the NAME section, then a type definition
.RB ( "struct ... {" ),
then the SYNOPSIS, then anywhere in the body. Pages in the core sections
(headers and sections 2, 4, 5, 7, 9) are weighted above library and command
pages, and a page found under several man roots is collapsed to one entry.
.SH COMPRESSION
Plain and
.B gzip
pages are read directly;
.BR zstd ", " xz ", and " bzip2
pages are read through the matching decompressor if it is installed, which
it will be on any system that stores its pages that way.
.SH EXAMPLES
.nf
.RS
# find the page that documents sockaddr, pick from a list
jafm sockaddr
# skip the picker, open the best match
jafm -1 getentropy
# only structs, printed rather than opened
jafm -t struct -l sockaddr
# whole word, open the winner
jafm -e -1 inet
.RE
.fi
.SH EXIT STATUS
.TP
.B 0
A page was opened, or
.B \-l
listed matches.
.TP
.B 1
Bad usage, no matches, or nothing was selected.
.SH ENVIRONMENT
.TP
.B MANPATH
Honored via
.BR manpath (1),
which jafm runs to find where your pages live.
.SH SEE ALSO
.BR man (1),
.BR manpath (1),
.BR apropos (1)
