Free full text search software for linux

TextSearch is a program that helps you search through a set of text files which are in a hierarchical structure, i.e. a directory structure. Each document is searched using a regular expression and an overview of the results is shown as a tree structure. By clicking on a file, it can be viewed, with matches being highlighted.

As opposed to other programs out there, focus is not so much on statistics, i.e. how often a word would occur in an entire corpus of files, but rather on occurrences in single files.

TextSearch is published as open source under the GPL.

Why do I need it?

a) Youre writing your diploma thesis about the occurences of certain terms in publications by various political parties, and you need a way to quickly look for a certain term in many files.
b) Youre a programmer, you have a large code tree, and youd just like to know where youve used sprintf() instead of snprintf().

Sethi Search Utility provides a simple command line utility to submit a search to Google, Yahoo!, or MSN.
Sethi Search Utility is a simple command line utility to submit a search to Google, Yahoo!, or MSN and show the (text) results on standard output. Support for several search engines is included.
Its currently in serious need of a re-write, especially to avoid scraping and become a good engine using the search APIs provided.
Enhancements:
- The Google configuration was updated.

nautilus-search-tool is a Nautilus extension to have "search files" on popup menu.

Amarok Full Screen provides a full screen front end for Amarok.

The look can be changed by custom THEMES.

Pyndexter (pronounced poindexter) is an abstraction layer for full-text indexing engines. It presents a uniform query syntax to the user, includes a basic but functional pure-Python indexer, and has adapters for Hype, Hyperestraier, Lucene, Lupy, Pyndex, Swish-e and Xapian.
How do I install it?
Pyndexter should be installable with setuptools:
easy_install pyndexter
Enhancements:
- The API has been revamped considerably and is now much more flexible and extensible.

Text::CPP is a full C Preprocessor in XS.

SYNOPSIS

use Text::CPP;
my $reader = new Text::CPP(
Language => CLK_GNUC99,
Options => {
...
},
Builtins => {
foo => this,
bar => that,
},
);
$reader->read("file.c");
while (my $token = $reader->token) {
print "Token: $tokenn";
}

$reader->data->{MyKey} = $MyData;

A fast C preprocessor in XS. This does not require an external C preprocessor, and will not fork() or exec() any external process.

USAGE

The following methods have been implemented, allowing the use of this module as a pure C preprocessor, or as a lexer for a C, C++ or Assembler-like language.

new Text::CPP(...)

Takes a hash or hashref with the following possible keys:

Language

Defines the source language to preprocess and/or tokenise. It may be any of:

CLK_GNUC89 - GNU C89
CLK_GNUC99 - GNU C99
CLK_STDC89 - Standard C89
CLK_STDC94 - Standard C94
CLK_STDC99 - Standard C99
CLK_GNUCXX - GNU C++
CLK_CXX98 - Standard C++ 98
CLK_ASM - Assembler

Options

A hashref of options for the preprocessor. Valid entries are given with alternative forms (from GNU cpp) in brackets.

Define (-D): array of strings or hash

Strings should be of the form NAME=VALUE.

Undef (-U): array of strings

DiscardComments (-C): boolean

DiscardCommentsInMacroExp (-CC): boolean

PrintIncludeNames (-H): boolean

NoLineCommands (-P): boolean

WarnComments (-Wcomment -Wcomments): boolean

WarnDeprecated (-Wdeprecated): boolean

WarningsAreErrors (-Werror): boolean

WarnImport (-Wimport): boolean

WarnMultichar (-Wmultichar): boolean

WarnSystemHeaders (-Wsystem-headers): boolean

Ignore errors in system header files.

WarnTraditional (-Wtraditional): boolean

WarnTrigraphs (-Wtrigraphs): boolean

WarnUnusedMacros (-Wunused-macros): boolean

Pedantic (-pedantic): boolean

PedanticErrors (-pedantic-errors): boolean

Implies, and overrides, Pedantic.

Remap (-remap): boolean

Deal with some brokennesses of MSDOS. Untested.

Trigraphs (-trigraphs): boolean

Traditional (-traditional): boolean

NoWarnings (-w): boolean

IncludePrefix (-iprefix): string

SystemRoot (-isysroot): string

Include (-include): array of strings

Include the specified files before reading the main file to be processed.

IncludeMacros (-imacros): array of strings

Include the specified files before reading the main file to be processed. Output from preprocessing these files is discarded. Files specified by IncludeMacros are processed before files specified by Include.

IncludePath (-I): array of strings

This include path is searched first.

SystemIncludePath (-isystem): array of strings

Specify the standard system include path, searched second.

AfterIncludePath (-idirafter): array of strings

This include path is searched after the system include path.

Builtins

A hashref of predefined macros. The values must be strings or integers. Macros in this hash will be defined before preprocessing starts. These correspond to true "builtin" macros. You should probably prefer to use the Define option.

$text = $reader->token

($text, $type, $flags) = $reader->token

Return the next available preprocessed token. Some tokens are not stringifiable. These include tokens of type CPP_MACRO_ARG, CPP_PADDING and CPP_EOF. Text::CPP returns a dummy string in the text field for these tokens. Tokens of type CPP_EOF should never actually be returned.

@tokens = $reader->tokens

Preprocess and return a list of tokens. This is approximately equivalent to:

push(@tokens, $_) while ($_ = $reader->token);

$reader->type($type)

Return a human readable name for a token type, as returned by $reader->token.

$reader->data

Returns a hashref in which user data may be stored by subclasses. This hashref is created with a new Text::CPP object, and is ignored for all functional purposes. The user may do with it as he wishes.

$reader->errors

In scalar context, returns the fatal error count. In list context, returns a list of warnings and errors encountered by the preprocessor. Thus scalar(@errors) >= $errors, since @errors will also contain the warnings.
