ecFlow变量
我们已经看到 ecFlow 使用一些变量
（variable），比如 ECF_HOME，ECF_INCLUDE。
共有三种变量：
- ecFlow 使用的变量，例如
ECF_HOME - 用户定义的变量，不应该以
ECF开头，推荐使用大写字母来定义变量。 - ecFlow 生成的变量，可以在 job 中使用，例如包含 suite 的日期
ECF_DATE。
Ecf脚本
之前的例子中，我们复制 t1.ecf 为 t2.ecf。
编辑这两个文件，以用户定义的变量 SLEEP 为参数调用 unix 的 sleep 命令。
%include <head.h>
echo "I will now sleep for %SLEEP% seconds"
sleep %SLEEP%
%include <tail.h>
suite definition
添加变量到 suite definition
Text
# Definition of the suite test.
suite test
edit ECF_INCLUDE "$ECF_HOME" # replace '$ECF_HOME' with the path to your ECF_HOME directory
edit ECF_HOME "$ECF_HOME"
family f1
task t1
edit SLEEP 20
task t2
edit SLEEP 20
endfamily
endsuite
Python
import os
from pathlib import Path
from ecflow import Defs, Suite, Task, Family, Edit
def create_family_f1():
return Family(
"f1",
Task("t1", Edit(SLEEP=20)),
Task("t2", Edit(SLEEP=20)))
print("Creating suite definition")
home = os.path.abspath(Path(Path(__file__).parent, "../../../build/course"))
defs = Defs(
Suite('test',
Edit(ECF_INCLUDE=home, ECF_HOME=home),
create_family_f1()))
print(defs)
print("Checking job creation: .ecf -> .job0")
print(defs.check_job_creation())
print("Saving definition to file 'test.def'")
defs.save_as_defs(str(Path(home, "test.def")))
# To restore the definition from file 'test.def' we can use:
# restored_defs = ecflow.Defs("test.def")
运行脚本：
$python test.py
Creating suite definition
# 4.8.0
suite test
edit ECF_INCLUDE '/g3/wangdp/project/study/ecflow/ecflow-tutorial-code/build/course'
edit ECF_HOME '/g3/wangdp/project/study/ecflow/ecflow-tutorial-code/build/course'
family f1
task t1
edit SLEEP '20'
task t2
edit SLEEP '20'
endfamily
endsuite
