 # maifetch
-a really lazy fetch tool for [maitea](https://maitea.app) written in go\
-also contains a little api wrapper for maitea too :D
+
+A lazy terminal fetch tool for [MaiTea](https://maitea.app), rewritten in
+GnuCOBOL for the current bounty direction.

-## configuration
+## Features
+
+- GnuCOBOL CLI implementation with no Go runtime dependency.
+- Preserves the original configuration priority:
+  command line > environment > config file > defaults.
+- Supports the original MaiTea config names and arguments:
+  `--access-token` / `-a` / `-t`, `--logo-size` / `-l`,
+  `--score-count` / `-s`, and `--config-file` / `-c`.
+- Fetches `/api/v1/profiles` and `/api/v1/plays` with authenticated `curl`
+  requests, then formats the same profile and recent-score fields as the Go
+  version.
+- Includes fixture-driven tests so CI can validate CLI parsing, JSON field
+  extraction, output formatting, and the no-token error path without a live
+  MaiTea token.
+
+## Requirements
+
+- GnuCOBOL 3.x or newer
+- `curl` for live MaiTea API requests
+
+On Debian or Ubuntu:
+
+```sh
+sudo apt-get update
+sudo apt-get install -y gnucobol curl
+```
+
+## Configuration
+
 | variable     | description                                        | default                                    | environment variable | cli argument          |
 |--------------|----------------------------------------------------|--------------------------------------------|----------------------|-----------------------|
-| access token | token for your MaiTea account (REQUIRED)           | `N/A`                                      | `MAITEA_TOKEN`       | `--access-token` `-a` |
-| logo size    | size of the ASCII logo (zero or negative disables) | `20`                                       | `MAITEA_LOGO_SIZE`   | `--logo-size` `-l`    |
-| score count  | amount of scores to display (max 12)               | `4`                                        | `MAITEA_SCORE_COUNT`  | `--score-count` `-s`  |
-| config file  | json file to store config variables                | [refer to below](#default-config-location) | `MAITEA_CONFIG_FILE` | `--config-file` `-c`  |
+| access token | token for your MaiTea account (required)           | `N/A`                                      | `MAITEA_TOKEN`       | `--access-token` `-a` `-t` |
+| logo size    | size of the ASCII logo, zero or negative disables  | `20`                                       | `MAITEA_LOGO_SIZE`   | `--logo-size` `-l`    |
+| score count  | amount of scores to display, max 12                | `4`                                        | `MAITEA_SCORE_COUNT` | `--score-count` `-s`  |

-### Default config location
-obtained from `os.UserConfigDir` 
+Example config:
+
+```json
+{
+  "accessToken": "your-token",
+  "scoreCount": 4,
+  "logoSize": 20
+}
+```
+
+### Default Config Location
+
+The COBOL rewrite follows the same practical defaults as the original Go
+implementation:
 
 | platform | location                                                    |
 |----------|-------------------------------------------------------------|
 | Windows  | `%APPDATA%/maifetch.json`                                   |
-| Linux    | `$XDG_CONFIG_HOME/maifetch.json`  `~/.config/maifetch.json` |
-| OSX      | `~/Library/Application Support/maifetch.json`               |
+| Linux    | `$XDG_CONFIG_HOME/maifetch.json` or `~/.config/maifetch.json` |
+| macOS    | `~/Library/Application Support/maifetch.json`               |
+
+## Build
+
+```sh
+make
+```
+
+Run the built executable:
+
+```sh
+./build/maifetch --access-token "$MAITEA_TOKEN" --logo-size 0
+```
+
+`--logo-size 0` disables the profile icon area, matching the original tool's
+no-logo mode. The COBOL implementation keeps a blank logo column when a
+positive logo size is configured because the original Go image-to-ASCII library
+does not have a direct GnuCOBOL equivalent.
 
-## how to build
-1. clone the project with `git clone https://github.com/HutchyBen/maifetch`
-2. build with `go build maifetch/cmd/maifetch`
-3. run outputted executable ensuring access token is either
-    - in config file
-    - in environment variables
-    - in command line options
+## Test
 
+```sh
+make test
+```
 
-## todo
-- test it properly
-- add friendly errors
+The test suite compiles the GnuCOBOL program and runs it against checked-in
+MaiTea JSON fixtures via `MAIFETCH_PROFILE_FIXTURE` and
+`MAIFETCH_PLAYS_FIXTURE`, avoiding any live network credentials in CI.
