fly through your shell history\n\n\n\n<img src=\"/docs/screenshot.png\" alt=\"screenshot\" width=\"400\">\n\n\n\nMcFly replaces your default `ctrl-r` Bash history search with an intelligent search engine that takes into account\n\nyour working directory and the context of recently executed commands. McFly's suggestions are prioritized\n\nin real time with a small neural network.\n\n \n\nTL;DR: an upgraded `ctrl-r` for Bash whose history results make sense for what you're working on right now.\n\n\n\n## Features\n\n\n\n* Rebinds `ctrl-r` to bring up a full-screen reverse history search prioritized with a small neural network.\n\n* Augments your shell history to track command exit status, timestamp, and execution directory in a SQLite database.\n\n* Maintains your normal Bash history file as well so that you can stop using McFly whenever you want.\n\n* Unicode support throughout.\n\n* Includes a simple action to scrub any history item from the McFly database and your shell history files.\n\n* Designed to be extensible for other shells in the future.\n\n* Written in Rust, so it's fast and safe.\n\n\n\n## Prioritization\n\n\n\nThe key feature of McFly is smart command prioritization powered by a small neural network that runs\n\nin real time. The goal is for the command you want to run to always be one of the top suggestions.\n\n\n\nWhen suggesting a command, McFly takes into consideration:\n\n\n\n* The directory where you ran the command. You're likely to run that command in the same directory in the future.\n\n* What commands you typed before the command (e.g., the command's execution context).\n\n* How often you run the command.\n\n* When you last ran the command.\n\n* If you've selected the command in McFly before.\n\n* The command's historical exit status. You probably don't want to run old failed commands.\n\n\n\n## Installation\n\n\n","file_path":"README.md","rank":95,"score":6.027897906553508},{"content":" let mut next_word_index: usize = 0;\n\n let

alt=\\\"screenshot\\\" width=\\\"400\\\">\\n\\n\\n\\nMcFly replaces your default `ctrl-r` Bash history search with an intelligent search engine that takes into account\\n\\nyour working directory and the context of recently executed commands. McFly's suggestions are prioritized\\n\\nin real time with a small neural network.\\n\\n \\n\\nTL;DR: an upgraded `ctrl-r` for Bash whose history results make sense for what you're working on right now.\\n\\n\\n\\n## Features\\n\\n\\n\\n* Rebinds `ctrl-r` to bring up a full-screen reverse history search prioritized with a small neural network.\\n\\n* Augments your shell history to track command exit status, timestamp, and execution directory in a SQLite database.\\n\\n* Maintains your normal Bash history file as well so that you can stop using McFly whenever you want.\\n\\n* Unicode support throughout.\\n\\n* Includes a simple action to scrub any history item from the McFly database and your shell history files.\\n\\n* Designed to be extensible for other shells in the future.\\n\\n* Written in Rust, so it's fast and safe.\\n\\n\\n\\n## Prioritization\\n\\n\\n\\nThe key feature of McFly is smart command prioritization powered by a small neural network that runs\\n\\nin real time. The goal is for the command you want to run to always be one of the top suggestions.\\n\\n\\n\\nWhen suggesting a command, McFly takes into consideration:\\n\\n\\n\\n* The directory where you ran the command. You're likely to run that command in the same directory in the future.\\n\\n* What commands you typed before the command (e.g., the command's execution context).\\n\\n* How often you run the command.\\n\\n* When you last ran the command.\\n\\n* If you've selected the command in McFly before.\\n\\n* The command's historical exit status. You probably don't want to run old failed commands.\\n\\n\\n\\n## Installation\\n\\n\\n\",\n \"file_path\": \"README.md\",\n \"rank\": 95,\n \"score\": 6.027897906553508\n },\n {\n \"content\": \" let

docker/podman\\n\\n* First install build dependencies\\n\\n```\\n\\n# dnf/rpm based distributions\\n\\nsudo dnf install libinput-devel\\n\\n\\n\\n# apt/deb based distributions\\n\\nsudo apt install libinput-dev\\n\\n```\\n\\n* Then build and install\\n\\n```\\n\\nmake build && make install\\n\\n```\\n\\n\\n\\n### Troubleshooting\\n\\n- First make sure you've restarted your system after installing.\\n\\n\\n\\n- Run following command to check if service is running properly (It should be running on X11).\\n\\n```\\n\\nsystemctl --user status gesture_improvements_gesture_daemon.service\\n\\n```\\n\\n\\n\\n- Open issue on github, with output of the above command\\n\\n### Uninstallation\\n\\n```\\n\\n# Without sudo/root\\n\\nsh

Wasm runner.
Takes a binary (wasm) or text (wat) WebAssembly module and instantiates it,
including calling the start function if one is present. Additional functions
given with --invoke are then called.
Usage:
wasmtime [-odg] [--enable-simd] [--wasi-c] [--disable-cache | \
--cache-config=<cache_config_file>] [--preload=<wasm>...] [--env=<env>...] [--dir=<dir>...] \
[--mapdir=<mapping>...] [--lightbeam | --cranelift] <file> [<arg>...]

--cache-config=<cache_config_file>] [--env=<env>...] [--dir=<dir>...] \
[--mapdir=<mapping>...] --invoke=<fn> [--lightbeam | --cranelift] <file> [<arg>...]
wasmtime --create-cache-config [--cache-config=<cache_config_file>]
wasmtime --help | --version
Options:
--invoke=<fn> name of function to run
-o, --optimize runs optimization passes on the translated functions
--disable-cache disables cache system
--cache-config=<cache_config_file>
use specified cache configuration;
can be used with --create-cache-config to specify custom file
--create-cache-config
creates default configuration and writes it to the disk,
use with --cache-config to specify custom config file
instead of default one
-g generate debug information
-d, --debug enable debug output on stderr/stdout
--lightbeam use Lightbeam for all compilation
--cranelift use Cranelift for all compilation
--enable-simd enable proposed SIMD instructions
--wasi-c enable the wasi-c implementation of `wasi_unstable`
--preload=<wasm> load an additional wasm module before loading the main module
--env=<env> pass an environment variable (\"key=value\") to the program
--dir=<dir> grant access to the given host directory
--mapdir=<mapping> where <mapping> has the form <wasmdir>::<hostdir>, grant access to
the given host directory with the given wasm directory name
-h, --help print this help message
--version print the Cranelift version

Usage:
wasmtime [-odg] [--enable-simd] [--wasi-c] [--disable-cache | \
--cache-config=<cache_config_file>] [--preload=<wasm>...] [--env=<env>...] [--dir=<dir>...] \
[--mapdir=<mapping>...] [--lightbeam | --cranelift] <file> [<arg>...]
wasmtime [-odg] [--enable-simd] [--wasi-c] [--disable-cache | \
--cache-config=<cache_config_file>] [--env=<env>...] [--dir=<dir>...] \
[--mapdir=<mapping>...] --invoke=<fn> [--lightbeam | --cranelift] <file> [<arg>...]
wasmtime --create-cache-config [--cache-config=<cache_config_file>]
wasmtime --help | --version
Options:
--invoke=<fn> name of function to run
-o, --optimize runs optimization passes on the translated functions
--disable-cache disables cache system
--cache-config=<cache_config_file>
use specified cache configuration;
can be used with --create-cache-config to specify custom file
--create-cache-config
creates default configuration and writes it to the disk,
use with --cache-config to specify custom config file
instead of default one
-g generate debug information
-d, --debug enable debug output on stderr/stdout
--lightbeam use Lightbeam for all compilation
--cranelift use Cranelift for all compilation
--enable-simd enable proposed SIMD instructions
--wasi-c enable the wasi-c implementation of `wasi_unstable`
--preload=<wasm> load an additional wasm module before loading the main module
--env=<env> pass an environment variable (\"key=value\") to the program
--dir=<dir> grant access to the given host directory
--mapdir=<mapping> where <mapping> has the form <wasmdir>::<hostdir>, grant access to
the given host directory with the given wasm directory name
-h, --help print this help message
--version print the Cranelift version
