由于某种原因,使用 FIFO 不能正常工作,所以我实现了这种奇怪。它使用文件在控制器实例(仅从终端运行它)和pdb 之间以不同的代码进行通信,该代码从任何地方调用。还使用猴子补丁将我们的新set_trace 转换为pdb。
import time
import pdb
IN_FILE = "in.pdb"
OUT_FILE = "out.pdb"
class _Receiver(object):
def __init__(self, in_file):
self.in_file = in_file
with open(in_file, "w") as file:
file.write("")
def readline(self):
x = ""
while x == "":
time.sleep(0.1)
with open(self.in_file, "r") as file:
x = file.readline()
with open(self.in_file, "w") as file:
file.write("")
return x
class _Sender(object):
def __init__(self, out_file):
self.out_file = out_file
with open(out_file, "w") as file:
file.write("")
def write(self, x):
with open(self.out_file, "a") as file:
file.write(x)
def flush(self):
pass
mypdb = pdb.Pdb(stdin=_Receiver(in_file=IN_FILE),
stdout=_Sender(out_file=OUT_FILE))
pdb.set_trace = mypdb.set_trace
在其他代码中使用断点:
from youcannameit import pdb
pdb.set_trace()
要连接到 pdb,请在 cmd 中运行主批处理脚本。它运作良好。不如 bash 版本好,所以我会把它留在那里,以防你选择使用它。您不能使用 CRT-C type q 代替。一旦你退出,我建议打开一个新的 cmd,因为在同一个中再次运行是有问题的。也许有更多批处理知识的人可以修复它。
主批处理脚本:
@echo off
set IN_FILE="in.pdb"
set OUT_FILE="out.pdb"
set LOCK="lock.lock"
echo running > %LOCK%
start /b read.cmd
timeout 1 /NOBREAK >NUL
echo PDB:
goto :write_pdb
:print_file
type %OUT_FILE%
timeout 1 /NOBREAK >NUL
NUL > %OUT_FILE% 2>NUL
goto :read_pdb
:read_pdb
for /f %%i in (%OUT_FILE%) do set size=%%~zi
if %size% gtr 0 goto :print_file
timeout 1 /NOBREAK >NUL
goto :read_pdb
:write_pdb
set /P INPUT=%=%
echo %INPUT% > %IN_FILE%
If /I "%Input%"=="q" goto :end
If /I "%Input%"=="quit" goto :end
If /I "%Input%"=="exit" goto :end
goto :write_pdb
:end
del %LOCK%
echo Exiting..
EXIT /B 0
辅助批处理脚本,以便我们可以同时打印和输入(将其命名为 read.cmd 并将其放在与主脚本相同的文件夹中):
@echo off
set IN_FILE="in.pdb"
set OUT_FILE="out.pdb"
set LOCK="lock.lock"
goto :read_pdb
:print_file
type %OUT_FILE%
timeout 1 /NOBREAK >NUL
NUL > %OUT_FILE% 2>NUL
goto :read_pdb
:read_pdb
if not exist %LOCK% goto :end
for /f %%i in (%OUT_FILE%) do set size=%%~zi
if %size% gtr 0 goto :print_file
timeout 1 /NOBREAK >NUL
goto :read_pdb
:end
如果你坚持使用 bash 版本::
#!/bin/bash
IN_FILE="in.pdb"
OUT_FILE="out.pdb"
echo PDB:
# trap ctrl-c and call ctrl_c()
trap ctrl_c INT
function ctrl_c() {
kill $READER >/dev/null 2>&1
exit 1
}
read_pdb(){
while true
do
if [ -s $OUT_FILE ]
then
cat $OUT_FILE
sleep 0.05
> $OUT_FILE
fi
done
}
write_pdb(){
while true
do
sleep 0.1
read user_inp
echo $user_inp > $IN_FILE
if [ "$user_inp" == "q" ];
then
kill $READER >/dev/null 2>&1
exit 1
fi
done
}
read_pdb &
READER=$!
write_pdb
要连接到终端中的断点,只需执行 bash 脚本。您必须确保路径(IN_FILE、OUT_FILE、LOCK)是您系统的实际路径。
