This is a simple GUI for the command line tool grep and pdfgrep
THIS PROJECT HAS MOVED TO: https://sourceforge.net/projects/documentgrep/
This program is a GUI for the command line tool grep and pdfgrep. Pdfgrep search text in multiple PDF files and grep can serach text in multiple text files. You can use regular expressions for the search (https://en.wikipedia.org/wiki/Regular_expression). This GUI and the command line tools work without indexing.
The following options are used: -i (ignore case) and -F (fixed strings), -n (Print page number or output lines) and -H (Print the file name for each match) from the command line tool. The -r option will be done by the program itself.
Performance:
This GUI works well when searching in several hundreds of documents (depends on the speed of your computer and the length of the documents).
Config Dir:
[homedir]/.config/pdfgrepgui
Available Languages:
- English
- German
You can add your own language by editing the file [homedir]/.config/pdfgrepgui/language.set

Embedded a lua script in an executable without LUA DLL (one file)
Builds an executable containing all the files of a LUA application. This executable will be autonomous, it will include all the resources of the application. This program checks, compiles each LUA unit, searches for "require" and dependencies, it automatically includes the necessary modules. It can also integrate other types of files: DLL, Exe, images... The work is simplified by adding pre-compilation directives.
On Linux only.
