orotool

Your Origins RO API client

Purpose

Work in progress

Licence

orotool is released under the GPL3+

Compiling the project

To compile orotool you will need:

• meson
• gcc with C++17 support

Dependencies

• lzma (optional)
• curlcpp (compulsory at the moment, bundled)
• curl (compulsory at the moment)
• libev (compulsory)
• boost (compulsory)
• simdjson (compulsory at the moment, bundled)
• restc-cpp (optional, bundled, currently broken)
• RapidJSON (optional, currently broken)
• SQLiteCpp (compulsory at the moment, bundled)
• SQLite (compulsory at the moment)
• date (compulsory, bundled)
• duckhandy (compulsory, bundled)
• sprout (compulsory)
• magic_enum (compulsory, bundled)
• gnulib (compulsory, bundled)

Building

1. download the source code
2. create an empty directory
3. cd into your new directory and run meson setup -Dbuildtype=release <path_to_orotool_source>
4. compile with the command ninja
5. if compilation succeeds, you will find the binary inside the src directory
6. run ninja install to copy files into your system install location

You can change the command at step 3 to customise certain aspects of orotool. You can for example specify --sysconfdir <path> for the path where orotool.conf should be found in. -Dprefix will change the install prefix. For example:

meson setup -Dprefix=/usr -Dsysconfdir=/etc -Dbuildtype=release ~/dev/orotool/

Other options can be found in meson_options.txt. In meson you specify options with the -Doption syntax to the setup subcommand, just like -Dbuildtype. For example -Dbase_url.

For options of type feature (see inside meson_options.txt) possible values are: enabled, disabled, auto. A short description of each:

• enabled the feature must be compiled in, configuration will fail if dependencies are missing
• disabled the feature is disabled
• auto the feature will only be compiled in if the required dependencies are present on the system

For more informations please read the meson documentation.

Details about supported options:

• base_url allows you to change the url of the remote API address (mostly useful when debugging)
• def_sqlite_db_name this is the default value for the db_path option in the config file
• tests enable building tests (currently it only has effect on some subprojects)
• with_sqlite if you want to compile with SQLite support (this is the only available backend at the moment)
• rest_lib which method will be used to access the remote API. nap is the internal one (curl+simdjson). restc-cpp is currently broken due to a bug upstream
• with_lzma adds support for JSON logs compression (option json_store_mode=xz in the config file)

Recipes

This is a collection of tricks, commands and SQL queries that you might find helpful.

Exporting JSON to file

If you saved JSON data to the database in compressed format (store_raw_json=true and json_store_mode=xz) you can export them to separate files with the following bash command (assuming current directory contains a originsro.db3 DB):

mkdir -pv split_json
cd split_json

digits=0000; n=0; while IFS= read -r line; do \
base64 --decode <<<"$line" | unxz --decompress > output"${digits:${#n}:${#digits}}${n}".txt; \
(( n++ )); \
done < <(sqlite3 ../debug/originsro.db3 'select source from source_store where format=2')

This will not export plain uncompressed JSON (format=1)

Getting min/max price of each item on the market now

With this query you can retrieve the min and max price of each item currently being sold (assuming database is up to date), along with their names, the name of the shop selling them and the total count of items of that type across all shops and all prices. Note that refined equipment or equipment with cards are considered to be all equivalent to the plain item.

SELECT title, name, MIN(price) AS min_price, MAX(price) AS max_price, SUM(amount) AS amount FROM (
SELECT shops.title, items.name, shop_items.price, items.item_id,
	shop_items.amount
	FROM shops
	LEFT JOIN shop_snapshots ON shop_snapshots.shop_id=shops.id
	LEFT JOIN shop_items ON shop_items.snapshot_id=shop_snapshots.id
	LEFT JOIN items ON shop_items.item_id=items.id
	WHERE shops.type=1 AND
		shop_snapshots.last_seen_date=(SELECT max(last_seen_date) FROM shop_snapshots)
) GROUP BY item_id

"Currently open" means shops seen on the same date the most recent shop was seen. In my current case my database was last updated 6 hours ago, this means I'm seeing the list of items that were being sold 6 hours ago.

Estimate JSON storage size

This returns an estimate in MiB of the total storage occupied by the saved JSON data

SELECT ROUND(CAST(SUM(pgsize) AS REAL)/(1024.0*1024.0), 2) FROM dbstat WHERE name='source_store'

Deleting JSON logs

You can delete the stored JSON whenever you want. It is adviced that you also set all source_id references to 0 in order to avoid wrong references to the new JSON logs getting stored in the future:

UPDATE items SET source_id=0;
UPDATE fame_list SET source_id=0;
UPDATE icons SET source_id=0;
UPDATE shop_snapshots SET source_id=0;
DROP TABLE IF EXISTS source_store;
VACUUM;
