This program was built for an optional uni project for the module "Software Development 1" in the course "Medieninformatik", first semester.
This program tries to achieve similar functionality to the good old unix grep, but does not try to resemble it completely. Thus, a few adjustments to our needs were made.
We do not provide any support regarding this project. When our project is ready to submit, it probably won't be updated.
It is NOT and under no circumstances intended to substitute any other utility, it is just for learning's sake.
- maven (version 3.6.3 or newer)
- Java 17 Runtime (Recommended: OpenJDK)
[ye@west ~]$ sudo dnf install -y maven java-17
[ye@west ~]$ sudo dnf install maven-openjdk17 --allowerasingye@west:~$ sudo apt install -y maven openjdk-17-jreOther debian-based distros could be similar, but that's untested!
After cloning the repository you just use the following command within the created folder:
mvn package
When the process of building finishes, you should find the jar-file in the folder target
You can also download a precompiled jar under releases
When the JRE is present and installed correctly you should be able to use the following command structure (provided you are in the target-folder):
java -jar YeOldeGrep-0.1.jar <args>
This program incorporates a bunch of functionality seen in grep. Some is pretty much identical, some is adjusted and some is not found in the original at all.
All functions in the following list shall be added to the end of the command seen above.
-l <query> <files>: shows all files in the list of arguments that contain the query.-i <query> <files>: shows all lines sorted by file in which the query occurs but case-insensitive.--help: shows a general help page, summarizing all functions.
This program is fully documented using javadoc. To generate the javadoc-files you may navigate to the project folder and run the following command:
mvn javadoc:javadoc
Using the optional flag -Dshow=private will add information about private methods to the generated javadoc-files.
