文档Chatblade
A CLI Swiss Army Knife for ChatGPT
Chatblade is a versatile command-line interface (CLI) tool designed to interact with OpenAI's ChatGPT. It accepts piped input, arguments, or both, and allows you to save common prompt preambles for quick usage. Additionally, Chatblade provides utility methods to extract JSON or Markdown from ChatGPT responses.
Note: You'll need to set up your OpenAI API key to use Chatblade.
You can do that by either passing --openai-api-key KEY or by setting an env variable OPENAI_API_KEY (recommended). The examples below all assume an env variable is set.

Making queries
A new conversation
You can begin any query by just typing. f.e.:
chatblade how can I extract a still frame from a video at 22:01 with ffmpeg
recall the last conversation
if you would like to recall the last conversation just call it back with -l
chatblade -l
Continue the last conversation
To continue the conversation and ask for a change within the context, you can again use -l but with a query.
chatblade -l can we make a gif instead from 00:22:01 to 00:22:04
-l is shorthand for -S last or the last session. We can keep track of and continue various distinct conversations using the session options
Picking between gpt-3.5 and 4
By default, gpt-3.5 is used, you can switch at any point to 4 by using -c 4 or the latest 4o ("omni") by using -c 4o.
Additionally, you can pass any arbitrary full model name, f.e. -c gpt-3.5-turbo-16k.
Chatting interactively
If you preferred to chat interactively instead just use chatblade -i.
Show streaming text (experimental)
You can also stream the responses, just like in the webui. At the end of the stream it will format the result. This can be combined in an interactive session
chatblade -s -i

Formatting the results
Responses are parsed and if chatblade thinks its markdown it will be presented as such, to get syntax highlighting. But sometimes this may not be what you want, as it removes new lines, or because you are only interested in extracting a part of the result to pipe to another command.
In that case you have 2 options:
-rfor raw, which just prints the text exactly as ChatGPT returned it, and doesn't pass it through Markdown.-efor extract, which will try to detect what was returned (either a code block or json) and extract only that part. If neither of those are found it does the same as-r
Both options can be used either with a new query, e.g.
chatblade -e write me a python boilerplate script that starts a server and prints hello world > main.py
or with the last result (json in this example)
chatblade -l -e | jq
Piping content into chatblade
If we have long prompts we don't want to type everytime, or just want to provide context for our query we can pipe into chatblade.
e.g.
curl https://news.ycombinator.com/rss | chatblade given the above rss can you show me the top 3 articles about AI and their links -c 4
The piped input is placed above the query and sent to ChatGPT.
or
chatblade what does this script do < script.sh
What gets sent to ChatGPT over the wire is:
piped input
-------
query
Session Options
Sessions are named conversations.
If you start chatblade with a session name SESS of your choice:
chatblade -S SESS can we make a gif instead from 00:22:01 to 00:22:04
chatblade will create a session called SESS if it does not exist, and it will store the current exchange (query-response pair) for SESS.
If such a session already exists, the saved conversation will be loaded and the new exchange will be appended.
Without a session argument, the exchange also gets stored in a session named last; however, subsequent sessionless invocation will overwrite the content of last. (You can continue a conversation that was started as a sessionless exchange by passing -S last, but last won't be a safe space for keeping a conversation, as the next sessionless invocation will clear it again.) The -l option is provided as a shorthand for -S last.
If you specify a session without a query:
chatblade -S SESS
chatblade will recall the conversation without modifying the session.
chatblade supports various operations on sessions. It provides the --session-OP options, where OP can be list, path, dump, delete, rename.
Checking token count and estimated costs
If you want to check the approximate cost and token usage of a previous query, you can use the -t flag for "tokens."
We could do this when passing in a lot of context like in the example above for instance.
curl https://news.ycombinator.com/rss | chatblade given the above rss can you show me the top 3 articles about AI and their links -t
This won't perform any action over the wire, and just calculates the tokens locally.
Use custom prompts (the system msg)
The system message is used to instruct the model how to behave, see OpenAI - Instructing Chat Models.
These can be loaded with -p. For convenience any file we place under ~/.config/chatblade/ will be picked up by this command.
So for example, given the following file ~/.config/chatblade/etymology, which contains:
I want you to act as a professional Etymologist and Quiz Generator. You have a deep knowledge of etymology and will be provided with a word.
The goal is to create cards that quiz on both the etymology and finding the word by its definition.
The following is what a perfect answer would look like for the word "disparage":
[{
"question": "A verb used to indicate the act of speaking about someone or something in a negative or belittling way.<br/> <i>E.g He would often _______ his coworkers behind their backs.</i>",
"answer": "disparage"
},
{
"question": "What is the etymological root of the word disparage?",
"answer": "From the Old French word <i>'desparagier'</i>, meaning 'marry someone of unequal rank', which comes from <i>'des-'</i> (dis-) and <i>'parage'</i> (equal rank)"
}]
You will return answers in JSON only. Answer truthfully and if you don't know then say so. Keep questions as close as possible to the
provided examples. Make sure to include an example in the definition question. Use HTML within the strings to nicely format your answers.
If multiple words are provided, create questions and answers for each of them in one list.
Only answer in JSON, don't provide any more text. Valid JSON uses "" quotes to wrap its items.
We can now run a command and refer to this prompt with -p etymology:
chatblade -p etymology gregarious
You can also point -p to a file path directly to load a system message from any arbitrary location
And since we asked for JSON, we can pipe our result to something else, e.g.:
chatblade -l -e > toanki
Configuring for Azure OpenAI
chatblade can be used with an Azure OpenAI endpoint, in which case in addition to the OPENAI_API_KEY you'll need to set the following environment variables:
OPENAI_API_TYPE:: Set toazure. As required by openai-pythonAZURE_OPENAI_ENDPOINT:: URL to your cognitive services' endpoint, e.g.https://eastus.api.cognitive.microsoft.com/. Please note this is a breaking change introduced byopenai-pythonand the previous environment variable name isOPENAI_API_BASEOPENAI_API_AZURE_ENGINE:: name of your deployment in Azure, f.e.my-gpt-35-turbo(maps to a specific model)
Note: that this will override any option for -c 3.5 or -c 4 which don't make sense in this case.
