# Filepattern Utility
[](https://filepattern.readthedocs.io/en/latest/?badge=latest)
[](https://pypi.org/project/filepattern/)
The `filepattern` Python utility is designed to information stored in file
names. A `filepattern` is essentially a simplified regular expression with named
groups, and regular expressions are valid `filepattern` expressions provided
they do not use groups.
The utility was born from the need to manipulate and organize image data from a
variety of microscopes, all of which have a systematic but different file naming
conventions. This made abstracting things like image stitching algorithms easier
to apply to files with disparate naming conventions by simply changing the
`filepattern` rather than generating new code to parse each new naming
convention. Although `filepattern` was born to wield against image data, it is
not limited to image data, and can handle filenames with any extension.

## Install
This utility is built in pure Python with no dependencies.
`pip install filepattern`
## Getting Started
What does a ``filepattern`` look like? It is probably easiest to show by
example. Say there is a folder with the following files:
```bash
my_data_folder/x000_y000_z001.tif
my_data_folder/x000_y000_z002.tif
my_data_folder/x000_y000_z003.tif
```
The `filepattern` for the above files would be `x000_y000_z00{z}.ome.tif`.
The curly brackets indicate a file name variable, and `{z}` indicates that the
number will be parsed and stored as a z value. If a similar regular expression
were to be written, then it would look like `x000_y000_z00([0-9]).ome.tif`,
which is not only longer but would require more code to parse the regular
expression.
To easily loop over the values, a `FilePattern` object can be created and used
to iterate over the files in order.
```python
import filepattern, pathlib
pattern = 'x000_y000_z00{z}.ome.tif'
path_to_files = pathlib.Path('/path/to/files')
fp = filepattern.FilePattern(path_to_files,pattern)
# Loop over all files that match the pattern
for files in fp():
# Files contains a list of all files with identical z-value
# In this case, there should only be one so select the first item
file = files[0]
# Each value in files is a dictionary containing the filename under the
# "file" key, and the z-value extracted from the file name under the "z" key
print(f"File {file['file']} has z-value {file['z']}")
```
The output should be as follows:
```bash
File my_data_folder/x000_y000_z001.tif has z-value 0
File my_data_folder/x000_y000_z002.tif has z-value 1
File my_data_folder/x000_y000_z003.tif has z-value 2
```
