# dlpt
Damogran Labs Python Tools, a collection of modules with utility functions to ease everyday Python
usage. It runs smoothly on windows, linux and mac-os.
Homepage: [https://damogranlabs.com/2021/01/dlpt/](https://damogranlabs.com/2021/01/dlpt/)
PyPi: [https://pypi.org/project/dlpt/](https://pypi.org/project/dlpt/)
Docs: [https://dlpt.readthedocs.io/en/latest/](https://dlpt.readthedocs.io/en/latest/)
Install: `pip install -U dlpt`
## Why?
This package main purpose is to stop reinventing the wheel on top of the built-in Python functions
in every single project. Everyday struggle with:
* how do I initialize logger and add file handler?
* how do I temporary change current working directory?
* how do I spawn a subprocess and add stdout on any exception?
* how do I get only directories inside some location?
* how do I parse JSON file with comments?
* how do I format time to string in one line?
* how do I dynamically import some module that is not on a `sys.path`?
* ...
These and many more everyday Python code questions should be covered with this library. Nothing extra,
just simplified.
Mostly built upon standard built-in code, but with a lot more straight-forward and less cluttered API.
## Modules
`dlpt.pth`: everything about paths and file/directory operations: list files/directories, copy/remove, get extensions, ...
`dlpt.utils`: everyhting we always need and never remember: list/dict comparison, values<->string transformation, module inspections, ...
`dlpt.log`: create new logger(s) and/or add common handlers (console/stream, file, ...) to any logger. Supports cross-process logging.
`dlpt.proc`: everything about common process use cases, but with more info on exceptions and easier straight-forward API.
`dlpt.time`: everything about time<->string transformation and code timing (timing decorator or special function wrapper)...
`dlpt.json`: read/write JSON files or python objects, with comments and smart pickling using `jsonpickle` library...
`dlpt.importer`: dynamically import python modules and inspect its object or call its functions/classes...
## Examples:
> How do I initialize logger and add file handler?
```python
# init default logger with console and file handler (file in <cwd>/log sub-directory)
import dlpt
logger = dlpt.log.create_logger("my_logger")
dlpt.log.add_console_hdlr(logger)
hdlr, file_path = dlpt.log.add_file_hdlr(logger, "dlpt_example.log")
log.debug(f"Logger initialised, file: {file_path}")
```
> How do I temporary change current working directory?
```python
import os
import dlpt
print(f"Current working directory: {os.getcwd()}")
dir_path = os.path.join(os.getcwd(), "..", "..")
with dlpt.pth.ChangeDir(dir_path):
print(f"Current temporary working directory: {os.getcwd()}")
print(f"Current working directory: {os.getcwd()}")
```
> How do I spawn a subprocess and add stdout on any exception?
```python
import sys
import dlpt
# a valid subprocess
args = [sys.executable, "-c", "import dlpt; print(dlpt.utils.float_to_str(12324.5678))"]
proc = dlpt.proc.spawn_subproc(args)
print(proc.stdout) # will print '12324.57'
# invalid subprocess, will throw exception
args = [sys.executable, "-c", "throw exception"]
dlpt.proc.spawn_subproc(args)
```
> How do I get only directories inside some location?
```python
import dlpt
files = dlpt.pth.get_files_in_dir_tree(os.getcwd(), exclude_ext=[".pyc"])
for file_path in files:
print(f"File {dlpt.pth.get_name(file_path)}: {file_path}")
```
> How do I parse JSON file with comments?
```python
import dlpt
file_path = input("Enter a path to a JSON file with comments: ")
data = dlpt.json.read(file_path)
# alternatively, if file was created with `dlpt.json.writeJsonpickle()`, user can:
data = dlpt.json.read_jsonpickle(file_path)
```
> How do I format time to string in one line?
```python
import dlpt
# 2 days, 4 hours, 6 mins, 12 sec, 0.33 milliseconds
sec = dlpt.time.time_to_seconds(h=52, m=6, s=12.033)
end_time = dlpt.time.sec_to_str(duration_sec, dlpt.time.TIME_FORMAT_HMS_STRING)
print(end_time) # will print: '52 h 6 min 12.33 sec'
```
> How do I dynamically import some module that is not on a `sys.path`?
```python
import dlpt
file_path = input("Enter a path to a python module that you wish to dynamically import: ")
importer = dlpt.importer.ModuleImporter(file_path)
print("Does module have an object with name 'myObject'? {importer.has_object('myObject')}")
# call a function of this module:
module = importer.get_module()
module.someFunction()
```
