Fake Compiler

Pretend as if something is compiling or busying in your terminal.

Usage

Run compiler: run subcommand

Run over a directory: fake-compiler run -d path_to_compile -C compiler_type

• -C option: specify the compiler type, i,e how fake-compiler interprets the given directory path_to_compile
• Supported compiler type: cxx and cargo
  • cxx: fake-compiler will iterate through the whole directory and print cmake style compiling logs of all files with .cpp/.c/.S extension
  • cargo: fake-compiler will parse Cargo.toml and Cargo.lock within directory root, resolving dependency graph and printing cargo style compiling logs

Or run with a config file: fake-compiler run -c config_file

• The config file contains parsed result of some directory. It has specific format, you should generate it by gen subcommand
• Actually it is equivalent to -d option, except that fake-compiler now no longer needs to explicitly parse the directory everytime

Optional flag: -t threads: specify the number of threads, default: 16

• Since fake-compiler does not actually do the compiling stuff, this flag essentially specifies how many threads are sleeping at the same time

Optional flag: -p bar: specify the style of progress bar/compiling logs

• YES, you can specify this. Each compiler has its own default progress bar, but you can explicitly specify others
• Supported progress bar: same as supported compiler type, i,e cxx and cargo
• This option only affects how the interpreted content is printed, it does not affect how to interpret the given directory

Generate config file: gen subcommand

You can generate config file by fake-compiler gen -C compiler_type -d path_to_compile -o output_file

• The generated file is bound to how specified compiler interprets the directory

Example config files

This repository is shipped with two example config files, placed at examples/ directory:

• examples/linux-6.12.17_cxx: linux 6.12.17 source code
• examples/router_cargo: Apollo Router Core

Try it out (need Go environment): go run . run -c examples/linux-6.12.17_cxx

Build

1. Setup Go environment, minimal version required: 1.23.0
2. Run make build
