Celeste Mod Structure Verifier

This tool allows you to check the structure and dependencies of your Celeste mods.

It checks for the following:

everest.yaml should exist and should be valid according to the everest.yaml validator

all decals, stylegrounds, entities, triggers and effects should be vanilla, packaged with the mod, or from one of the everest.yaml dependencies

the dialog files for vanilla languages should not contain characters that are missing from the game's font, or those extra characters should be included in the zip

If you enable path checking, which is useful when you check a zip with a single map that is going to be included in a contest or collab, it will also check for the following:

files in Assets/, Graphics/Atlases/, Graphics/ColorGrading/ and Tutorials/ should have this path: [base path]/[asset folder name]/[subfolder]/[anything]

XMLs in Graphics/ should match: Graphics/[asset folder name]xmls/[subfolder]/[anything].xml

there should be exactly 1 file in the Maps folder, and its path should match: Maps/[map folder name]/[subfolder]/[anything].bin

if there is an `English.txt`, dialog IDs should match: [asset folder name]_[anything]_[anything]

File upload on the website can be quite slow. To reduce the file size, you can delete the Audio folder from the zip you upload.

For faster verifying, you can use the Mod Structure Verifier Discord bot. If you host a contest/collab that has its own Discord server, you can invite the bot on it and preset the folder names, so that mappers just have to drop their zip files in a designated channel to have them verified.
