 # Rusty-tasks
-A rewrite of an older CLI todo system without python and regex
 
-## Goals
+A personal task management system built on plain text and works in your favorite editor
 
-- [ ] BLAZING FAST!
-- [ ] replace python with rust
-- [ ] replace regex with a markdown parsing library
-- [ ] learn some rust along the way

-- Take advantage of Markdown for formatting

+
+
+## Installing 
+
+```bash
+git clone https://github.com/andrei-stoica/rusty-tasks.git
+cd rusty-task cargo install --path .
+```
+
+Alternatively, there is a binary download for AMD64 Linux machines available 
+on the [releases page](https://github.com/andrei-stoica/rusty-tasks/releases).
+Just drop that anywhere on your PATH. I recommend adding `~/bin` to your PATH
+and dropping the executable there.
+
+If you are not on an AMD64 Linux machine, you will need to build from source.
+I have not tested this on other platforms, so I hesitate to provide binaries
+for them.
+
+## Usage
+***WARNING:*** *This documentation can be ahead of the releases on the GH release page*
+```help
+Usage: rusty-tasks [OPTIONS]
+
+Options:
+  -c, --config <FILE>        set config file to use
+  -C, --current-config       show current config file
+  -d, --date <DATE>          view a specific date's file (format: YYYY-MM-DD)
+  -p, --previous <PREVIOUS>  view previous day's notes [default: 0]
+  -l, --list                 list closest files to date
+  -n, --number <NUMBER>      number of files to list [default: 5]
+  -L, --list-all             list closest files to date
+  -v, --verbose...           increase logging level
+  -h, --help                 Print help
+  -V, --version              Print version
+```
+
+Just use `rust-task` to access today's notes file.
+
+Use `rust-task -p <n>` to access a previous day's file where `<n>` is the number
+of days back you want to go. If a file does not exist for that day, it will
+default to the closest to that date. A value of 0 represents today's file.
+
+Alternatively, use `--date` or `-d` to specify a date specifically. Preferably
+in the format year-month-day, padding with zero is optional. However, if the
+year, or, year and month are omitted they will be filled in with the current
+date's year and month. For example, If the current date is `2024-2-30`, the
+string `4` will resolve to `2024-2-4`, and `1-4` will resolve to `2024-1-4`.
+
+Specify a custom config location with `-c`, otherwise, it will scan for a config
+in the locations specified in the [config section](#config). If no config
+exists it will create one. To see what config is being loaded you can use `-C`.
+
+To list your existing notes you can use `-L`. For a subset of these use
+`-l` combined with `-n` to specify the number of files to list. This will be
+the closest `n` files to the specified date, which is today by default. Specify
+the target date using the `-p` as mentioned earlier
+
+## Config
+
+The config should be located in the following locations:
+
+- `~/.config/rusty_task.json`
+- `~/.rusty_task.json`
+- `$PWD/.rusty_task.json`
+
+If there is no config it will be created at `~/.config/rusty_task.json`.
+
+Example config:
+```
+{
+  "editor": "nano",
+  "sections": [
+    "Daily",
+    "Weekly",
+    "Monthly"
+  ],
+  "notes_dir": "~/notes"
+}
+```
+
+- `editor` is the executable that will be launched to modify the notes file
+- `sections` is a list of Sections that will be carried over from the previous
+day's notes
+    * only uncompleted tasks are carried over
+    * You can use other sections for scratch space and other journaling tasks
+- `notes_dir` is the directory that stores your daily notes 
+    * this could be set to your obsidian vault if you want it to work with
+      all of your other notes (I recommend checking out [obsidian.nvim](https://github.com/epwalsh/obsidian.nvim)
+      if you want to interact with an obsidian vault in neovim)
