# efipy
#####- efipy stands for '*easy file iterator python*'
python based easy file iterator, with recursive option, and file filtering. useful when you need to apply some function to a set of files.

## requires
- safer-prompt-toolkit

## documentation
#### run(func, root_path=None, b_recursive=False, files_filter="*", b_yield_folders=False)
run func on all files that match.  
Parameters:  
>  - func - a callable, the function to be executed for each matching file in directories.  
>    func receives a single parameter of type pathlib.Path and returns nothing.  
>  - root_path - defaults to None. a directory, or a file in which to iterate. if file is given than runs only on that one file. if None is given, will prompt the user for a path, with path auto completion and validation.  
>  - b_recursive - defaults to False. if True, will search recursively in sub-folders. if False will limit search to current dir.   
>  - files_filter - defaults to "*" (allows any path). a filter to limit search results for files, see "glob" for further details. 
>  - b_yield_folders - defaults to False. weather to pass paths to folders (not files) to func as well (if you want to iterate on folders as well as files)

returns:
> - a list of pathlib.Path instances that contains all the paths that matched the search (the exact same ones that were sent to func).     
 
info: 
1. if you don't like the fact that func recives a complicated pathlib.Path instance, you can just write `path=str(path)` in context:
2. take advantage of the root_path=None option. when no root path is supplied, the computer will prompt you for a path with some nice UI.
```python
def func(path):
    path=str(path)
    # ... other code to do with path ...

efipy.run(func)

```

#### inquire_output_path(default)
prompts the user for an output path, and returns it. if path already exists, asks the user to confirm overwrite. also has path auto-completion and validation.  
Parameters:  
>  - default - the default path to prompt user with

returns:
> - the validated path the user entered     
 
## example usages
example 1:  
lets say I have a folder in wich all the files are numbered. and lets say I want to rename every
even third file, so that it ends wit a q, for example:  
```
 before:                    -> after:  
 file_one_000.txt   
 some_other_file_001.md  
 some_third_file_002.txt    -> some_third_file_002q.txt  
 some_fourth_file_003.txt  
 yea_dogs_004.txt  
 wow_005.log                -> wow_005q.log
``` 
```python
import os,efipy
def rename(path):
    # rename files that end with divide by 3
    if int(path.stem[-3:])%3 == 0:
        name_no_extention,extention = os.path.splitext(path)
        os.rename(path,name_no_extention + "q" + extention)

efipy.run(rename)
```

example 2:
```python
import efipy
def func(path):
    print(str(path))

efipy.run(func,root_path="some_root_folder",b_recursive=True,files_filter="*.q")
# when run on the following file tree, will produce the following output:

# file tree:
# ─── some_root_folder
#     ├── f0.q
#     ├── dir1
#     │   ├── f1.r
#     │   └── f2.q
#     └── dir2
#        ├── f3.q
#        └── f4.q

# output, the program will print out (maybe not in this order):
#  some_root_folder/f0.q
#  some_root_folder/dir1/f2.q
#  some_root_folder/dir2/f3.q
#  some_root_folder/dir2/f4.q
```
