NAME
Files-Containing - Search for strings in files
SYNOPSIS
use Files-Containing;
.say for files-containing("foo", :files-only)
for files-containing("foo") {
say .key.relative;
for .value {
say .key ~ ': ' ~ .value; # linenr: line
}
}
for files-containing("foo", :count-only) {
say .key.relative ~ ': ' ~ .value;
}
DESCRIPTION
Files-Containing exports a single subroutine files-containing which produces a list of files and/or locations in those files given a certain path specification and needle.
EXPORTED SUBROUTINES
files-containing
The files-containing subroutine returns either a list of filenames (when the :files-only named argument is specified) or a list of pairs, of which the key is the filename, and the value is a list of pairs, in which the key is the linenumber and the value is the line in which the needle was found.
Positional Arguments
needle
The first positional argument is the needle to search for. This can either be a Str, a Regex or a Callable. See the documentation of the Lines::Containing module for the exact semantics of each possible needle.
If the needle is a Callable, then the dynamic variable $*IO will contain the IO::Path object of the file being processed.
files or directory
The second positional argument is optional. If not specified, or specified with an undefined value, then it will assume to search from the current directory.
It can be specified with a list of files to be searched. Or it can be a scalar value indicating the directory that should be searched for recursively. If it is a scalar value and it is an existing file, then only that file will be searched.
Named Arguments
:batch
The :batch named argument to be passed to the hypering logic for parallel searching. It determines the number of files that will be processed per thread at a time. Defaults to whatever the default of hyper is.
:count-only
The count-only named argument to be passed to the lines-containing|https://raku.land/zef:lizmat/lines-containing subroutine, which will only return a count of matched lines if specified with a True value. False by default.
:degree
The :degree named argument to be passed to the hypering logic for parallel searching. It determines the maximum number of threads that will be used to do the processing. Defaults to whatever the default of hyper is.
:dir
The :dir named argument to be passed to the paths subroutine. By default will look in all directories, except the ones that start with a period.
Ignored if a list of files was specified as the second positional argument.
:extensions
The :extensions named argument indicates the extensions of the files that should be searched.
Ignored if a :file named argument was specified. Defaults to all extensions.
:file
The :file named argument to be passed to the paths subroutine. Ignored if a list of files was specified as the second positional argument.
:files-only
The :files-only named argument determines whether only the filename should be returned, rather than a list of pairs, in which the key is the filename, and the value is a list of filenumber / line pairs.
:follow-symlinks
The :follow-symlinks named argument to be passed to the paths subroutine. Ignored if a list of files was specified as the second positional argument.
:i or :ignorecase
The :i (or :ignorecase) named argument indicates whether searches should be done without regard to case. Ignored if the needle is not a Str.
:include-dot-files
The :include-dot-files named argument is a boolean indicating whether filenames that start with a period should be included.
Ignored if a :file named argument was specified. Defaults to False, indicating to not include filenames that start with a period.
:invert-match
The :invert-match named argument is a boolean indicating whether to produce files / lines that did NOT match (if a true value is specified). Default is False, so that only matching files / lines will be produced.
The :m (or :ignoremark) named argument indicates whether searches should be done by only looking at the base characters, without regard to any additional accents. Ignored if the needle is not a Str.
:max-count=N
The :max-count named argument indicates the maximum number of lines that should be reported per file. Defaults to Any, indicating that all possible lines will be produced. Ignored if :files-only is specified with a true value.
:offset=N
The :offset named argument indicates the value of the first line number in a file. It defaults to 0. Ignored if the :files-only named argument has been specified with a true value.
:sort
The :sort named argument indicates whether the list of files obtained from the paths subroutine should be sorted. Ignored if a list of files was specified as the second positional argument. Can either be a Bool, or a Callable to be used by the sort routine to sort.
:type=words|starts-with|ends-with|contains
Only makes sense if the needle is a Cool object. With words specified, will look for needle as a word in a line, with starts-with will look for the needle at the beginning of a line, with ends-with will look for the needle at the end of a line, with contains will look for the needle at any position in a line. Which is the default.
