Usage

ChatGPT.CLI:
An .NET ChatGPT tool.

Usage:
ChatGPT.CLI [options]

Options:
-f, --inputFiles <inputfiles>              The relative or absolute path to the input files
-d, --inputDirectory <inputdirectory>      The relative or absolute path to the input directory
-o, --outputDirectory <outputdirectory>    The relative or absolute path to the output directory
--outputFiles <outputfiles>                The relative or absolute path to the output files
-p, --pattern <pattern>                    The search string to match against the names of files in the input directory
-r, --recursive                            Recurse into subdirectories of input directory search
-e, --extension <extension>                The output file extension
-s, --settingsFile <settingsfile>          The relative or absolute path to the settings file
--temperature <temperature>                What sampling temperature to use, between 0 and 2. Higher values like 0.8 will make the output more random, while lower values like 0.2 will make it more focused and deterministic.
--topP <topp>                              An alternative to sampling with temperature, called nucleus sampling, where the model considers the results of the tokens with top_p probability mass. So 0.1 means only the tokens comprising the top 10% probability mass are considered.
--presencePenalty <presencepenalty>        Number between -2.0 and 2.0. Positive values penalize new tokens based on whether they appear in the text so far, increasing the model's likelihood to talk about new topics.
--frequencyPenalty <frequencypenalty>      Number between -2.0 and 2.0. Positive values penalize new tokens based on their existing frequency in the text so far, decreasing the model's likelihood to repeat the same line verbatim.
--maxTokens <maxtokens>                    The maximum number of tokens to generate in the chat completion.
--apiKey <apikey>                          Override OpenAI api key. By default OPENAI_API_KEY environment variable is used.
--model <model>                            ID of the model to use. See the model endpoint compatibility table for details on which models work with the Chat API.
--directions <directions>                  The system message (directions) helps set the behavior of the assistant. Typically, a conversation is formatted with a system message first, followed by alternating user and assistant messages.
-t, --threads <threads>                    The number of parallel job threads
--quiet                                    Set verbosity level to quiet
--version                                  Show version information
-?, -h, --help                             Show help and usage information

Examples

• Using .NET tool chat command:

C# to VB

chat -d ./ -e vb -p *.cs --directions "You are C# to VB conversion expert. Convert input code from C# to VB. Write only converted code."

C# to F#

chat -d ./ -e fs -p *.cs --directions "You are C# to F# conversion expert. Convert input code from C# to F#. Write only code."

Refactor C# code

chat -d ./ -e cs -p *.cs --directions "You are C# expert. Refactor C# code to use fluent api. Write only code."

Write API documentation

chat -d ./ -e md -p *.cs --directions "You are a technical documentation writer. Write API documentation for C# code. If XML docs are missing write them."
