Gear Query

Gear query is an easy to use command line tool to keep track and query outdoor / backpacking equipment.

Dependencies

To install it a Rust compiler and Cargo are needed, which could be installed by following this guide.

Install

$ git clone https://gitlab.com/petervaro/gear.git
$ cd gear
$ cargo install --path .
$ printf 'export PATH=$PATH:$HOME/.cargo/bin\n' > ~/.bashrc

Gear List

The gear list file uses the TOML format.

There's a single entity type, the item, which could be used to describe the gear list. But before it could be used, the meta section's values needs to be specified.

Meta

Units

These values are used to properly represent the data in the items. Currently the weight and price formatters could be specified, each with a unit symbol and the position of the symbol (either 'PREFIX' or 'SUFFIX').

Example:

# Here we describe that all weight values are in grams and
# the 'g' unit should be put after the value, e.g. 12g
[meta.weight]
symbol = "g"
position = "SUFFIX"

# Here we describe that all price values are in dollars and
# the '$' symbol should be put before the value, e.g. $34.55
[meta.price]
symbol = "$"
position = "PREFIX"

Validators

Validators could be defined optionally. Their main purpose is to make sure for example that there are no typos regarding the specified values in the gear list or that all items define a specific attribute.

Example:

[meta.groups]
values = ["Shelter", "First Aid Kit", "Electronics"]

[meta.distances]
values = ["Short", "Long"]

[meta.temperatures]
values = ["Warm", "Cold"]

Item

An item is a piece of gear that must have a kind attribute, a string. All the other attributes are optional, but they could be the followings:

• name: string
• group: string
• weight: integer
• price: float
• distances: list of strings
• temperatures: list of strings

There are no predefined values, distances or temperatures could be arbitrary as well the group an item belongs to.

There are 2 main sections of the gear list where items could be specified:

• base: According to the following definition:

  Base weight (the weight of a backpack plus the gear inside & outside it, excluding consumables such as food, water, and fuel, which vary depending on the duration and style of trip) — Wikipedia

• consumables: Everything else

Example

[[base]]
kind = "Rucksack"
weight = 1201
price = 149.99
distances = ["Short"]
temperatures = ["Warm", "Cold"]

[[base]]
kind = "Water Filter"
name = "MSR TrailShot Micro"
group = "Kitchen"
weight = 146
price = 39.95
distances = ["Long"]
temperatures = ["Warm", "Cold"]

# The following specifies two main scenarios:
# - short distance: 1L water in bottle and 1L water in reservoir, and
# - long distance: 2L water in bottles and 3L water in reservoir

[[consumables]]
kind = "Water"
name = "In Bottle"
weight = 1000
distances = ["Short", "Long"]
temperatures = ["Warm", "Cold"]

[[consumables]]
kind = "Water"
name = "In Bottle"
weight = 1000
distances = ["Long"]
temperatures = ["Warm", "Cold"]

[[consumables]]
kind = "Water"
name = "In Reservoir"
weight = 1000
distances = ["Short", "Long"]
temperatures = ["Warm", "Cold"]

[[consumables]]
kind = "Water"
name = "In Reservoir"
weight = 2000
distances = ["Long"]
temperatures = ["Warm", "Cold"]

Usage

Simple Usage

# Either change the directory where the `gear.toml` file is
$ cd path/to/gear.toml
$ gear --all

# Or specify the path as a positional argument in which
# case the name of the TOML file doesn't matter
$ gear path/to/gear/list/toml --all
