NAME

App::Rak - a CLI for searching strings in files

SYNOPSIS

$ rak foo      # look for "foo" in current directory recursively

$ rak foo bar  # look for "foo" in directory "bar" recursively

$ rak '/ << foo >> /'    # look for "foo" as word in current directory

$ raku foo --files-only  # look for "foo", only produce filenames

$ raku foo --before=2 --after=2  # also produce 2 lines before and after

DESCRIPTION

App::Rak provides a CLI called rak that allows you to look for a needle in (a selection of files) from a given directory recursively.

To a large extent, the arguments are the same as with the grep utility provided on most Unixes.

Note: this is still very much in alpha development phase. Comments and suggestions are more than welcome!

POSITIONAL ARGUMENTS

pattern

The pattern to search for. This can either be a string, or a regular expression (indicated by a string starting and ending with /), or a Callable (indicated by a string starting with { and ending with }.

path

Optional. Either indicates the path of the directory (and its sub-directories), or the file that will be searched. By default, all directories that do not start with a period, will be recursed into (but this can be changed with the --dir named argument).

By default, all files will be searched in the directories. This can be changed with the --file named argument.

SUPPORTED NAMED ARGUMENTS

All named arguments are optional. Any unexpected named arguments, will cause an exception with the unexpected named arguments listed.

-A or --after or --after-context

Indicate the number of lines that should be shown after any line that matches. Defaults to 0. Will be overridden by a -C or --context argument.

-B or --before or --before-context

Indicate the number of lines that should be shown before any line that matches. Defaults to 0. Will be overridden by a -C or --context argument.

-C or --context

Indicate the number of lines that should be shown around any line that matches. Defaults to 0. Overrides any a -A, --after, --after-context, -B, --before or --before-context argument. argument.

--highlight

Indicate whether the pattern should be highlighted in the line in which it was found. Defaults to True if --human is (implicitely) set to True, else defaults to False.

--highlight--after

Indicate the string that should be used at the end of the pattern found in a line. Only makes sense if --highlight is (implicitely) set to True. Defaults to the empty string if -o or --only-matching is specified with a True value, or to the terminal code to end bold otherwise.

--highlight--before

Indicate the string that should be used at the end of the pattern found in a line. Only makes sense if --highlight is (implicitely) set to True. Defaults to a space if -o or --only-matching is specified with a True value, or to the terminal code to start bold otherwise.

--human

Indicate that search results should be presented in a human readable manner. This means: filenames shown on a separate line, line numbers shown, and highlighting performed. Defaults to True if STDOUT is a TTY (aka, someone is actually watching the search results), otherwise defaults to False.

-l or --files-only or --files-with-matches>

If specified with a true value, will only produce the filenames of the files in which the pattern was found. Defaults to False.

-o or --only-matching

Indicate whether only the matched pattern should be produced, rather than the line in which the pattern was found. Defaults to False.

--output-file

Indicate the path of the file in which the result of the search should be placed. Defaults to STDOUT.

--trim

Indicate whether lines that have the pattern, should have any whitespace at the start and/or end of the line removed. Defaults to True if no context for lines was specified, else defaults to False.

-V or --version

If the only argument, shows the name and version of the script, and the system it is running on.
