Elite Dangerous Market Connector 5.7.0

What Is Elite Dangerous Market Connector?

Elite Dangerous Market Connector ("EDMC") is a third-party application for use with Frontier Developments' game "Elite Dangerous". Its purpose is to facilitate supplying certain game data to, and in some cases retrieving it from, a number of websites and other tools.

To achieve this it utilises the Journal Files written by the game when played on a PC. It also makes use of Frontier's Companion API ("Frontier's CAPI"), accessible once you've authorised this application.

EDMC has a plugin system which many other developers have made use of to extend its functionality.

Find out more on the EDMC Wiki.

NB: This application is of no use with a Console game account. We now test against, and package with Python 3.11.x. As a consequence of this we no longer support Windows 7, due to Python 3.10.x itself not supporting Windows 7. Also, Windows 8.1 reaches End-Of-Life on 2023-01-10, so we will no longer support that OS as of that date.

As has become routine now, various anti-virus software are reporting a false positive on our installer and/or files it contains. I've pre-emptively uploaded the installer to VirusTotal if you want to check what it's saying. Please see our Troubleshooting/AV-false-positives FAQ for further information.

Release 5.7.0​

This release re-enables CAPI queries for Legacy players. As a result, the 'Update' button functionality is now restored for Legacy players, along with "Automatically update on docking" functionality.

• We now test against, and package with, Python 3.11.1, 32-bit.
• This release is functionally identical to 5.7.0-rc1, as no problems were reported with that.
• As noted above, Legacy players now have CAPI functionality once more. Plugin developers check below for how you can determine the source galaxy of such data.
• Due to a bug it turned out that a workaround for "old browsers don't support very long URLs" had been inactive since late 2019. As no-one has noticed or complained we've now removed the defunct code in favour of the simple webbrowser.open(<url>).Testing showed that all of Firefox, Chrome and Chrome-based Edge worked with very long URLs without issues.
• EDMC.exe -n had been broken for a while, it now functions once more.
• Some output related to detecting and parsing gameversionfrom Journals has been moved from INFO to DEBUG. This returns the output of any EDMC.exe command to the former, quieter, version.

Bugs​

​

• A corner case of "game not running" and "user presses 'Update' button" would result in an empty uploaderID string being sent to EDDN. Such messages are still accepted by the EDDN Gateway, and the Relay then obfuscates this field anyway. So, at worse, this would make it look like the same uploader was in lots of different places. This has been fixed.
• The message about converting legacy replay.jsonl was being emitted even when there was no file to convert. This has been fixed.

Plugin Developers​

​

• An erroneous statement about "all of Python stdlib" in PLUGINS.md has been corrected. We don't/can't easily include all of this. Ask if any part of it you require is missing.
• In order to not pass Legacy data to plugins without them being aware of it there is now a new function cmdr_data_legacy(), which mirrors the functionality of cmdr_data(), but for Legacy data only. See PLUGINS.md for more details.
• The data passed to cmdr_data() and cmdr_data_legacy() is now correctly typed as CAPIData. This is a sub-class of UserDict, so you can continue to use it as such. However, it also has one extra property, source_host, which can be used to determine if the data was from the Live or Legacy CAPI endpoint host. See PLUGINS.md for more details.
• If any plugin had been attempting to make use of config.get_int('theme'), then be aware that we've finally moved from hard-coded values to actual defined constants. Example use would be as in:

​

from config import config
from theme import theme

active_theme = config.get_int('theme')
if active_theme == theme.THEME_DARK:
    ...
elif active_theme == theme.THEME_TRANSPARENT:
    ...
elif active_theme == theme.THEME_DEFAULT:
    ...
else:
    ...

But remember that all tkinter widgets in plugins will inherit the main UI current theme colours anyway.

• The contents of NavRoute.json will now be loaded during 'catch-up' when EDMarketConnector is (re-)started. The synthetic StartUp (note the capitalisation) event that is emitted after the catch-up ends will have state['NavRoute'] containing this data.However, the Fileheader event from detecting a subsequent new Journal file will blank this data again. Thus, if you're interested in "last plotted route" on startup you should react to the StartUp event. Also, note that the contents will indicate a NavRouteClear if that was the last such event. PLUGINS.md has been updated to reflect this.
• If you've ever been in the habit of running our develop branch, please don't. Whilst we try to ensure that any code merged into this branch doesn't contain bugs, it hasn't at that point undergone more thorough testing. Please use the stable branch unless otherwise directed.
• Some small updates have been made in edmc_data as a part of reviewing the latest update to coriolis-data. We make no guarantee about keeping these parts of edmc_data up to date.Any plugins attempting to use that data should look at alternatives, such as FDevIDs/outfitting.csv.A future update might remove those maps, or at least fully deprecate their use by plugins. Please contact us now if you actually make use of this data.
