LALang

LALang

This repository is made for the first 5 tasks of the discipline of compiler construction that occured during the first semester of 2022 at UFSCar (Universidade Federal de São Carlos) with professor Daniel Lucrédio.

Objective

Create a lexer for the language LA that is made by the professors Jander Moreira, Helena de Medeiros Caseli and Daniel Lucrédio, for the discipline of Algorithm Construction and Programming.

Dependencies

To build the project I found that old versions of antlr do not tranpile correctly for the current go antlr runtime, so I sugest using the most recently version of each dependency.

• GO (>= 1.18)
• Antlr4 (>= 4.10.1)
• GNU make

Optional Dependencies

• docker
• docker-compose

Build

To build the executable simply run make.

make

After that an executable will be generated and put under the directory build. With the name EXECNAME-VERSION, where EXECNAME is variable that can be set during the build stage, e.g.:

EXECNAME=<exec_name> make

It may be easier to build it using docker in case antlr executables are not linked correctly on the system, building it like that can be done using the build/docker target:

make build/docker

Test

To execute the tests simply run the test rule on the Makefile:

make test

After that the results will be located on a directory named test-results in the same directory.

It is also possible to execute it the tests inside a docker container:

make test/docker

How to Run

After the executable has been built simply run it over the command line passing the name of the input and output files, e.g.:

./exec_name-version <input> <output>
