x86-info-term

x86-info-term is a curses-based viewer for x86 instruction info built with Python 3. It combines the following data sources:

Features

Offline use: after the data sources are downloaded on the first run, requires no network access to run
More advanced filtering: multiple filters are allowed, and so is filtering by regular expression (using Python's regex syntax). Filter terms can be prefixed by ! to negate the filter meaning. For example, the filter avx-512 !_mask will show all AVX-512 operations but filter out the masking variants.
Keyboard-only navigation: using a combination of vim- and emacs-style key bindings, x86-info-term is sure to delight and/or annoy everyone.
100% Pretty Cool

Data sources

s: switch main data source view (toggling between Intel intrinsics data or uops.info instructions)

Scrolling

<count>: a number can be prefixed to any vertical scroll to multiply the movement, like in vim.
Ctrl-Y: one line up
Ctrl-E: one line down
Ctrl-U: one half-page up
Ctrl-D: one half-page down
Page Up: one page up
Page Down: one page down (who would've thought?)
h, Left: scroll tables left (right now, just the performance data from uops.info)
l, Right: scroll tables right

Cursor movement

This is for the intrinsic-selection cursor, not for text editing: see "Filtering" below for that

<count>: a number can be prefixed to any movement to multiply the movement, like in vim. For example, 33j moves 33 rows down, and 33J moves 330 rows down. A count used with the g/G commands moves to an absolute line number.
j, Down: one row down
k, Up: one row up
J: ten rows down
K: ten rows up
u: one half-page up
d: one half-page down
g, Home: first row
G, End: last row

Detail view

Each intrinsic can be expanded/collapsed to show/hide complete data

Filtering

f, /, Tab: from the normal browsing mode, start entering a filter
most normal keys, arrow keys, delete/backspace, etc.: edit the filter with usual key meanings
Enter, Tab: keep filter, return to browsing mode
Esc: remove current filter and return to browsing mode
Ctrl-F: move cursor forward one character
Ctrl-B: move cursor back one character
Ctrl-W: delete word before cursor
Ctrl-U: delete line before cursor
Ctrl-K: delete line after cursor
