weirdgrep

Weirdgrep is a tool that allows you to search through huge files (initially designed to look through pages of code).

Installation

$ cargo install weirdgrep

Usage

$ weirdgrep -h
weirdgrep 1.0.2
Vaelio <archelio@protonmail.com>
Regex parser to search through files.

USAGE:
    weirdgrep [OPTIONS] <REGEX> <ENDTAG> <PATH>

ARGS:
    <REGEX>     Regex to apply
    <ENDTAG>    End Tag for the match
    <PATH>      File to parse

OPTIONS:
    -a, --add-markers    Add markers to better show which line matched
    -h, --help           Print help information
    -n, --numbers        Print line numbers for each printed lines starting from 0
    -V, --version        Print version information
    -w <WITHIN>          Switch to scope mode, and use this regex as a search and (regex, endtag) as
                         boundaries of the search afterwards

By default the tool will search for <REGEX> inside <PATH> and will print each matches until <ENDTAG> is reached. (This <ENDTAG> can be a regex aswell)

It is usefull when you want to extract for exemple every functions of a code page where the signature matches <REGEX>

You can further improve the granularity by adding the -w <WITHIN> switch which makes the tool search for this regex instead and then go forward and backward to respectively find <ENDTAG> and <REGEX> args. (This <WITHIN> option can also be a regex)

Example

$ weirdgrep 'Function<.+' 'EndFunction' -w '.+/invite/.+' instructions.hasm -n
1660535: Function<createUrl>28016(1 params, 16 registers, 0 symbols):
1660536: 	LoadThisNS          	Reg8:1

1660577: 	Add                 	Reg8:4, Reg8:2, Reg8:4
1660578: 	LoadConstString     	Reg8:2, UInt16:6648
1660578: 	; Oper[1]: String(6648) '/invite/'
1660579: 
[REDACTED]
1660611: EndFunction

$ wc -l instructions.hasm
