如何将stdin上的输入发送到Makefile中定义的python脚本?
给出这个问题的答案,哪个有效如何将stdin上的输入发送到Makefile中定义的python脚本?,python,linux,bash,variables,makefile,Python,Linux,Bash,Variables,Makefile,给出这个问题的答案,哪个有效 define NEWLINE endef define PYTHON_SCRIPT_CODE import sys print("hi") endef SDK_PATH := $(shell echo \ '$(subst $(NEWLINE),@NEWLINE@,${PYTHON_SCRIPT_CODE})' | \ sed 's/@NEWLINE@/\n/g' | python -) default: @echo 'SDK Pa
define NEWLINE
endef
define PYTHON_SCRIPT_CODE
import sys
print("hi")
endef
SDK_PATH := $(shell echo \
'$(subst $(NEWLINE),@NEWLINE@,${PYTHON_SCRIPT_CODE})' | \
sed 's/@NEWLINE@/\n/g' | python -)
default:
@echo 'SDK Path Detected: $(SDK_PATH)'
如何通过管道将数据传输到python std中?例如:
define PYTHON_SCRIPT_CODE
import sys
print("hi")
print(sys.stdin.read())
endef
# pseudocode
SDK_PATH := $(shell bash --version | PYTHON_SCRIPT_CODE)
default:
@echo 'SDK Path Detected: $(SDK_PATH)'
将输出:
SDK Path Detected: hi
GNU bash, version 4.4.19(1)-release (x86_64-pc-linux-gnu)

新示例,无需将内容管道化到Python脚本中:
#!/usr/bin/make -f
ECHOCMD:=/bin/echo -e
SHELL := /bin/bash
define NEWLINE
endef
VERSION := $(shell bash --version)
# With this, you cannot use single quotes inside your python code
define PYTHON_VERSION_CODE
import re, sys;
program_version = """${VERSION}"""
match = re.search("Copyright[^\d]+(\d+)", program_version);
if match:
if int( match.group(1) ) >= 2018:
sys.stdout.write("1")
else:
sys.stdout.write( match.group(1) )
else:
sys.stdout.write("0")
endef
# Due to this, you cannot use single quotes inside your python code
PYTHON_SCRIPT_RESULTS := $(shell echo \
'$(subst $(NEWLINE),@NEWLINE@,${PYTHON_VERSION_CODE})' | \
sed 's/@NEWLINE@/\n/g' | python -)
all:
printf 'Results: %s\n' "${PYTHON_SCRIPT_RESULTS}"
结果:
对我来说,避免所有命令行引用问题的最简单方法是使用GNUmake的
$(file)
函数将代码写入文件。您甚至可以在定义d变量中使用#
作为Python注释:
VERSION := $(shell bash --version)
# With this, you can use any form of quotes inside your python code
define PYTHON_VERSION_CODE :=
# -*- coding: iso-8859-15 -*-
import re, sys;
program_version = "${VERSION}"
match = re.search("Copyright[^\d]+(\d+)", program_version);
if match:
if int( match.group(1) ) >= 2018:
sys.stdout.write("1")
else:
sys.stdout.write( "match:" + match.group(1) )
else:
sys.stdout.write("0")
endef
$(file > test.py,$(PYTHON_VERSION_CODE))
PYTHON_SCRIPT_RESULTS := $(shell python test.py)
.PHONY: all
all:
@echo $(PYTHON_SCRIPT_RESULTS)
这个解决方案可以局限于GNUmake吗?或者你需要一个“可移植”的版本吗?你能想到的任何解决方案都是非常受欢迎的。
VERSION := $(shell bash --version)
# With this, you can use any form of quotes inside your python code
define PYTHON_VERSION_CODE :=
# -*- coding: iso-8859-15 -*-
import re, sys;
program_version = "${VERSION}"
match = re.search("Copyright[^\d]+(\d+)", program_version);
if match:
if int( match.group(1) ) >= 2018:
sys.stdout.write("1")
else:
sys.stdout.write( "match:" + match.group(1) )
else:
sys.stdout.write("0")
endef
$(file > test.py,$(PYTHON_VERSION_CODE))
PYTHON_SCRIPT_RESULTS := $(shell python test.py)
.PHONY: all
