Pay Respect

Typed a wrong command? Pay Respect will try to correct your wrong console command simply by pressing F!

How to Pay Respect

The binary is named pay-respect, by adding an alias to your shell configuration:

# Note: You may need to have the binary exposed in your path
alias f="pay_respect"

You can now press F to Pay Respect!

Installing

If you are using Arch Linux, you can install from AUR directly:

paru -S pay_respect

Otherwise, you can use cargo to compile the project:

cargo build --release

and the binary can be found at target/release/pay_respect.

Rule Files

Rule files are parsed at compilation. What actually gets compiled is a HashMap that contains patterns and suggestions for a specific command.

Syntax of a rule file (placed under rules):

# this field should be the name of the command
command = "world"

# you can add as much section of this as you like
[[match_output]]
# the suggestion of this section will be used for the following patterns of the command output
pattern = [
	"pattern 1",
	"pattern 2",
]
# this will change the first argument to `fix`, while keeping the rest intact
suggest = "{{command[0]}} fix {{command[2:]}}"

[[match_output]]
pattern = [
	"pattern 1",
]
# this will add a `sudo` before the command if:
# - the `sudo` is found by `which`
# - the last command does not contain `sudo`
suggest = '''
#[executable(sudo), !cmd_contains(sudo)]
sudo {{command}}'''

The placeholder is evaluated as following:

• {{command}}: All the command without any modification
• {{command[1]}}: The first argument of the command (the command itself has index of 0)
• {{command[2:5]}}: The second to fifth arguments. If any of the side is not specified, them it defaults to the start (if it is left) or the end (if it is right).

The suggestion can have additional conditions to check. To specify the conditions, add a #[...] at the first line (just like derive macros in Rust). Available conditions:

• executable: Check if the argument can be found by which
• cmd_contains: Check if the last user input contains the argument
• err_contains: Check if the error of the command contains the argument

Current Progress

We need more rule files!
