output_path = "typescript_plain.log"
# Specify the desired screen dimensions (columns x rows)
columns = 80 # please remember the columns for godsake.
# if you think it would be slow, use pypy instead.
rows = 100000 # what could go wrong now?
# Create a Screen object with the specified dimensions
screen = pyte.Screen(columns, rows)
# Create a ByteStream to handle ANSI control codes
stream = pyte.ByteStream(screen)
typescript_bytes = open(typescript_path,'rb').read()
# Insert ANSI control codes
stream.feed(typescript_bytes)
# Get the content with ANSI control codes
content = screen.display
plain_content ="\n".join(content).strip()
# Write the content to a file
with open(output_path, "w+") as file:
file.write(plain_content)

for ipython one use %history for viewing history.

# view all history across all sessions
%history -g
# view specific session history, like session 1
%history 1/
# -o for showing output, -p for appending ">>>" in front of input lines, -t for translating magic functions into valid python code
%history -opt

# please define "history_output_path" beforehand
import readline
# Get the total number of history items in the current session
history_length = readline.get_current_history_length()
# Iterate over each history item and print the command
with open(history_output_path, 'w+') as f:
for i in range(1, history_length + 1):
item = readline.get_history_item(i)
print(item)
f.write(item+"\n")

在pdb中 或者在breakpoint断点中 只能获取到当前会话的历史

import readline; print([readline.get_history_item(i+1) for i in range(readline.get_current_history_length())])

Hackers are good at converting arbitrary actions into scripts.

At every step below we need file records.

Thoughs -> Actions -> Scripts -> Programs -> Systems

Human learn from trial and error, which is the origin of every good program, and REPL can be a better place than web based jupyter notebook. So we might want to find some command line alternative to jupyter.

Typically we need history, command output, filter out those errorneous commands, and save the output.

R has that functionality.

# only current session history is keeped.

# view history in popup
