spyc is aCLI tool that monitors yourCPP code and automatically compiles and executes the code whenever there is a change in the file.
spyc is designed mainly for competitive programmers so that they can efficiently debug and execute their code for multiple test cases without compiling again and again.
spyc also supports some of the common GCC flags used in competitive programming.
Usingnpm
npm install -g spyc
npm install --save-dev spyc
To runspyc write.
spyc<yourfile.cpp> [,options]
For CLI options, use-h or--help.
spyc -h
spyc allows user to provide or change the input file at runtime without stopping the currently runningspyc program, this help programmers to check their code on multiple test cases without much effort.
For example clickhere.
spyc also allows users to see theircpp file or input file at runtime with the help ofcat option.
For example clickhere.
Inspyc user can also see the past stats usingstats options for performance comparison. This helps the user to check and compare the efficiency of their code on different test cases.
For example clickhere.
spyc also support some of the common gcc flags like,
| Flags | |
|---|---|
| std | std - Specify the C++ version or ISO standard version. |
| Wall | Turns on lots of compiler warning flags. |
| Werror | Turn any warning into a compilation error. |
| Wextra | Enables extra flags not enabled by -Wall. |
| Wshadow | Enable warning for Variable Shadowing. |
| O0 | No optmization. |
| O3 | Higher level of optmization. |
| fsanitize | Sanitizer for runtime checks. (eg. --fsanitize=address) |
You guys can also use my preferred GCC flag options for compiling the code usingquick flag.
spyc ./sample.cpp --quick
quick option will enable the following gcc flag combination.
g++ -DLOCAL -std=c++17 -Wshadow -Wall -o<output><yourfile.cpp> -fsanitize=address -fsanitize=undefined -D_GLIBCXX_DEBUG -g
Run command.
spyc ./sample.cpp
Run command.
spyc ./sample.cpp --input=<inputfile>
or
spyc ./sample.cpp -i=<inputfile>
Inspyc, we can also change or provide input at runtime without restarting the tool.This will help users to check their code on different test cases without wasting time on compiling and executing the code manually.
Run command.
--input=./in
or
-i=./in
spyc can also display input file or cpp code at runtime without pausing or stopping the tool.
This helps competitive programmers to see and debug their code or check the input file within thespyc tool.
--cat=<filename>
Inspyc, users can also see stats from past executions. This will help the user to optimize their code by comparing the execution time of their code.
