## Features

- **Multi-format support**: LAS, DLIS, ASCII/CSV/TXT/DAT
- **Automatic mnemonic standardization**: GR, RHOB, NPHI, DT, SP, CALI, RT, etc.
- **Batch processing**: Parse entire directories recursively
- **Customizable naming**: Override default standard names
- **Case-insensitive extensions**: Works with .las/.LAS, .dlis/.DLIS, .csv/.CSV, etc.
- **Pandas integration**: Returns clean DataFrames ready for analysis

---

## Installation

```bash
pip install lasmnemonicsid
```

This installs support for **all formats** (LAS, DLIS, ASCII/CSV/TXT).

---

## Quick Start

### LAS Files

```python
from LASMnemonicsID import parseLAS

# Parse single LAS file
df = parseLAS("well.las")
print(df.head())

# Parse directory
data = parseLAS("/path/to/las/files/")
for filename, df in data.items():
    print(f"{filename}: {df.shape}")
```

### DLIS Files

```python
from LASMnemonicsID import parseDLIS

# Parse single DLIS file
df = parseDLIS("well.dlis")
print(df.columns)

# Parse directory
data = parseDLIS("/path/to/dlis/files/")
```

### ASCII/CSV/TXT Files

```python
from LASMnemonicsID import parseASCII

# Parse CSV
df = parseASCII("well_log.csv", depth_col="DEPTH")

# Parse tab-separated TXT
df = parseASCII("well_log.txt", delimiter="\t")

# Parse directory
data = parseASCII("/path/to/csv/files/")
```

---

## Advanced Usage

### Custom Preferred Names

```python
preferred = {
    "deepres": "RT",
    "deepres_preferred_original": "AT90",
    "gamma": "GR"
}

df = parseLAS("well.las", preferred_names=preferred)
```

### Batch Processing

```python
from pathlib import Path

dir_path = Path("/data/wells/")
data = parseLAS(dir_path, verbose=True, preferred_names=preferred)

for fname, df in data.items():
    print(f"{fname}: {df.shape}")
    print(df.head(3))
```

### Mixed Format Directories

```python
las_data = parseLAS("/data/wells/")
dlis_data = parseDLIS("/data/wells/")
ascii_data = parseASCII("/data/wells/")

all_data = {**las_data, **dlis_data, **ascii_data}
```
