Can't cue eval with an expression

[Winael]

Hi everyone,

as a new comer to cuelang, I'm trying create a personal side project to train myself. Basically is to create a dataset os Stadia games, that i could request with cue to create tools that will help me to create shortcuts, searching games from CLI, etc.
Nothing important, but it help me to understand how cuelang works, and be able then to share my knowledge around me to advocate around cuelang (and why not, this project could be useful for Stadia users too)

So this is my repo right know :

https://github.com/Winael/stadiaCue

The thing is, when i try to evaluate my code without any expression, it works

$ cue eval ./... && echo 'OK' || echo 'KO'
[...]
gameList: ["Crayta", "Assassin's Creed Odyssey", "Assassin's Creed Origins", "Assassin's Creed Syndicate", "Assassin’s Creed Unity", "Assassin's Creed Valhalla", "Attack On Titan 2: Final Battle", "AVICII Invector", "Baldur's Gate 3 Early Access", "Borderlands 3", "Cake Bash", "Celeste", "Chronos: Before the Ashes", "Cosmic Star Heroine", "Ary and the Secret of Seasons", "Cthulhu Saves Christmas", "Cyberpunk 2077", "Darksiders Genesis", "Dead by Daylight", "Destiny 2", "Destroy All Humans!", "DIRT 5", "Disco Elysium - The Final Cut", "Doom 2016", "DOOM 64", "DOOM Eternal Standard Edition", "DRAGON BALL XENOVERSE 2", "DRAGON QUEST XI S: Echoes of an Elusive Age", "A Place for the Unwilling"]
// ---
purchasedGames: ["assassins_creed_odyssey", "assassins_creed_origins", "assassins_creed_unity", "cake_bash", "crayta", "dragon_quest_xi_echoes_of_an_elusive_age"]
claimedGames: ["ary_and_the_secret_of_seasons", "avicii_invector", "celeste", "crayta", "cthulhu_saves_christmas", "dead_by_daylight", "destiny_2"]
OK

but if i try to evaluate with an expression, for ex to request the gameList

cue eval -e 'gameList' ./... && echo "OK" || echo "KO"
// /home/vjobard/Documents/Stadia/stadiaCue/channels
reference "gameList" not found:
    --expression:1:1
KO

And I can't export anything.

I'm pretty sure I miss something but I don't know what.

If someone could help me on this, it could be very nice.

Thx a lot
Winael

@Winael after a quick glance, the reason this is happening is that gameList is not a field defined in all the ./... packages. Instead it's only defined for ./games/all_games/... packages:

$ cue eval -e gameList ./games/all_games/...
["Crayta", "Assassin's Creed Odyssey", "Assassin's Creed Origins", "Assassin's Creed Syndicate", "Assassin’s Creed Unity", "Assassin's Creed Valhalla", "Attack On Titan 2: Final Battle", "AVICII Invector", "Baldur's Gate 3 Early Access", "Borderlands 3", "Cake Bash", "Celeste", "Chronos: Before the Ashes", "Cosmic Star Heroine", "Ary and the Secret of Seasons", "Cthulhu Saves Christmas", "Cyberpunk 2077", "Darksiders Genesis", "Dead by Daylight", "Destiny 2", "Destroy All Humans!", "DIRT 5", "Disco Elysium - The Final Cut", "Doom 2016", "DOOM 64", "DOOM Eternal Standard Edition", "DRAGON BALL XENOVERSE 2", "DRAGON QUEST XI S: Echoes of an Elusive Age", "A Place for the Unwilling"]

OK, thx for your help

I believed that my package was games, so it's not totally clear

When I run

cue eval -e gameList ./games/all_games/...

./games/all_games/... is in fact where I can find the leafs where my data are, isn't it ?

./games/all_games/... is in fact where I can find the leafs where my data are, isn't it ?

./games/all_games/... is simply a specification of the inputs to cmd/cue, packages in this case. See cue help inputs for more details: it explains the various inputs cmd/cue can consume, along with details of what ... means etc.
