# Function: re (Resize SDXL LoRA)
# Description:
#   This function resizes an SDXL LoRA (Low-Rank Adaptation) model using the resize_lora.py script.
#   It applies a specific resizing recipe to reduce the size of the LoRA while maintaining its effectiveness.
#
# Usage:
#   re <target_file>
#
# Parameters:
#   $1 (target_file): Path to the input LoRA safetensors file to be resized.
#
# Actions:
#   1. Calls the resize_lora.py script with the following arguments:
#      - Verbose output (-vv)
#      - Custom resizing recipe (-r fro_ckpt=1,thr=-3.55)
#      - Path to the SDXL checkpoint file (ponyDiffusionV6XL_v6StartWithThisOne.safetensors)
#      - Path to the input LoRA file
#
# Recipe Explanation:
#   - fro_ckpt=1: Uses the Frobenius norm of the checkpoint layer as the score metric
#   - thr=-3.55: Sets a threshold for singular values at 10^-3.55 ≈ 0.000282 times the reference
#
# Notes:
#   - This function assumes the resize_lora.py script is located at ~/source/repos/resize_lora/
#   - The SDXL checkpoint file is expected to be in ~/ComfyUI/models/checkpoints/
#   - Output will be verbose (-vv) for detailed information during the resizing process
#   - The resized LoRA will be saved in the same directory as the script by default

# This function, `update_conda`, automates the process of upgrading all packages in every conda environment.

# 1. Retrieves the list of all conda environments using `conda env list` and extracts their names.
# 2. Iterates through each environment name.
# 3. Activates each environment using `conda activate`.
# 4. Upgrades all packages in the activated environment using `conda upgrade --all -y`.
# 5. Deactivates the environment using `conda deactivate`.
# 6. Prints a message indicating that all environments have been upgraded.
#
# Note: This script assumes that the user has the necessary permissions to activate and deactivate conda environments.
#       It also assumes that `conda` is installed and properly configured in the user's PATH.
#
# Usage:
# Simply call the `update_conda` function in your shell to upgrade all packages in all conda environments.

# Function: list_word_freqs
# Description:
#   This function analyzes text files in a specified directory and lists the most frequent words (tags).
#
# Usage:
#   list_word_freqs <target_directory>
#
# Parameters:
#   - target_directory: The directory containing the text files to analyze.
#
# Functionality:
#   1. Combines all .txt files in the target directory into a single temporary file.
#   2. Uses awk to process the combined file:
#      - Ignores common words like "a", "the", "and", etc.
#      - Converts all words to lowercase and removes non-alphabetic characters.
#      - Counts the frequency of each word.
#   3. Sorts the words by frequency in descending order.
#   4. Displays the top 40 most frequent words along with their occurrence count.
#
# Output:
#   Prints a list of the 40 most frequent words in the format: <frequency> <word>
#
# Note:
#   - This function is useful for analyzing tag frequencies in image caption files or similar text-based datasets.
#   - The list of ignored words can be modified to suit specific needs.
#   - The function creates a temporary file which is automatically removed after processing.

# Function: chop_lora
# Description:
#   This function processes a LoRA (Low-Rank Adaptation) model file by selectively
#   keeping or removing specific layers based on predefined presets. It uses the
#   chop_blocks.py script to perform the actual layer manipulation.
#
# Usage:
#   chop_lora <input_file>
#
# Parameters:
#   $1 - The input LoRA model file (typically a .safetensors file)
#
# Presets:
#   The function defines several presets, each represented by a 21-digit binary string:
#   - ringdingding: This vector string was used for the Stoat LoRA.
#   - squeaker: I really have no idea what this is.
#   - heavylifter: Keeps only one specific layer that seems to learn the most.
#   - style1 and style2: Different configurations for style transfer
#   - beeg: A configuration that keeps only the largest layers.
#   - all: Keeps all layers
#   - allin: Keeps only the input layers
#   - allmid: Keeps only the middle layers
#   - allout: Keeps only the output layers
#
# Actions:
#   1. Extracts the base name of the input file (without extension)
#   2. Iterates through each preset
#   3. For each preset, generates an output filename and runs the chop_blocks.py script
#   4. The script creates a new LoRA file with only the specified layers retained
#
# Output:
#   Creates multiple output files, one for each preset, named as:
#   "<base_name>-<preset_name>.safetensors"
#
# Notes:
#   - Requires the chop_blocks.py script to be located at ~/source/repos/resize_lora/chop_blocks.py
#   - The binary strings represent which layers to keep (1) or remove (0)
#   - This function allows for quick generation of multiple variants of a LoRA model,
#     each emphasizing different aspects or effects

# Function: seed
# Description:
#   This function extracts the seed value from a LoRA (Low-Rank Adaptation) model's metadata.
#
# Usage:
#   seed <file_path>
#
# Parameters:
#   $1 - The path to the LoRA model file (usually a .safetensors file)
#
# Actions:
#   1. Takes the file path as an argument
#   2. Uses Python to read the safetensors file
#   3. Extracts the metadata from the file
#   4. Attempts to retrieve the 'ss_seed' value from the metadata
#   5. Prints the seed value if found, or 'Not found' if not present
#
# Notes:
#   - Requires Python 3 with the 'safetensors' module installed
#   - The seed is typically used to reproduce the exact training conditions of the LoRA
#   - If the seed is not found, it may indicate the LoRA was created without recording this information

#
# Usage:
#   png2mp4
#
# Parameters:
#   None (uses all PNG files in the current directory)
#
# Actions:
#   1. Sets the frame rate to 8 fps
#   2. Uses glob pattern to include all PNG files in the current directory
#   3. Scales the output video to 1024x1024 resolution

#   7. Outputs the result as 'out.mp4' in the current directory
#
# Notes:
#   - Requires ffmpeg to be installed and accessible in the system path
#   - PNG files should be in the current directory
#   - Output video will be named 'out.mp4' and placed in the current directory
#   - Adjust the framerate, scale, or CRF value as needed for different results
