Design scripts to be easily integrated into build pipelines and CI/CD workflows by using standard I/O streams instead of hardcoded file paths. Scripts that read from stdin and write to stdout can be easily composed in pipelines, redirected, and incorporated into various build systems without modification.
Design scripts to be easily integrated into build pipelines and CI/CD workflows by using standard I/O streams instead of hardcoded file paths. Scripts that read from stdin and write to stdout can be easily composed in pipelines, redirected, and incorporated into various build systems without modification.
Example - Before:
if __name__ == "__main__":
project_root = Path(__file__).resolve().parents[2]
patcher_path = project_root / "vendor" / "nerd-fonts" / "font-patcher.py"
source = patcher_path.read_text(encoding="utf-8")
patch_set = extract_patch_set_values(source)
out_path = project_root / "src" / "font" / "nerd_font_attributes.zig"
# Write results to out_path
Example - After:
import sys
if __name__ == "__main__":
# Read from stdin if no arguments provided
if len(sys.argv) > 1:
with open(sys.argv[1], "r", encoding="utf-8") as f:
source = f.read()
else:
source = sys.stdin.read()
patch_set = extract_patch_set_values(source)
# Write results to stdout
print(generate_zig_output(patch_set))
This approach allows the script to be used in various CI contexts: cat input.txt | python script.py > output.zig or as part of more complex build rules without requiring code changes.
