In broader way, there is two way to install the antlr4 in the machine(specially in windows).
1-Manual Installation
install everything manually like
- install java development kit (JDK).
- download antlr4 , runtime jar file.
- setup all the environment variables etc.
we are not going to use manual installation.
2-Easy Installation
here we need only python latest install in our system.
- install python from official website : https://www.python.org/downloads/ , during python installation make sure that you checked the below Add Python 3.6 to PATH check-box
- after installation of python , open command line (cmd) and check the python installation is done or not. you can see Python 3.12.0 is installed.
- similarly check for pip is also installed or not. and if pip is updated one then its very good.
- if python and pip is there , then just run below script into cmd.
pip install antlr4-toolsabove script will download everything like jdk , antlr4 jar file and will also set required environment setup.
Now antlr4 is installed in the system along with all the dependency and environment variables. to check it run below script in cmd.
Now everything is ready for antlr4 , we need to write the grammar and parse the any script to generate the parse tree.
