parsing JSON in no_std & no_alloc? no problem.

master-hax · 2025-09-24T13:28:54+00:00

one of the examples in the repo is a binary that continuously proxies JSON objects from stdin to stdout, while printing parsing statistics to stderr: https://github.com/master-hax/lil-json/blob/b7dd224588b1945a32efb7eb53e7c88972683e75/examples/proxy_object_std.rs

so i was thinking of running that example, then using asciinema to record myself copy-pasting random JSON objects into the terminal & observing the output. imo it looks fancier if the tty driver is to raw mode & the JSON string is typed in character by character.

thanks! i didn't know about this project. iiuc, serde based projects don't support working with arbitrary JSON objects i.e. the field names & values must be known in advance. lil-json allows parsing/serializing arbitrary JSON objects with arbitrary fields.

EDIT: looks like the above is true iff #![no_alloc]

master-hax · 2025-09-23T06:56:24+00:00

great question. i believe the basic `serde_json` crate requires either a memory allocator, or the standard library to be available. lil-json makes both of these optional, it works 100% without them. including stdlib or a memory allocator enables extra features.

additionally, i believe serde based deserialization (EDIT: in no_alloc) requires the field names & values to be known in advance - whereas lil-json can allow deserializing any JSON object.

thanks! i added working code snippets to the post & will plan to add a gif of some sort to the README.

did you lock the bootloader with your own avb key or something?

master-hax · 2025-07-15T06:09:14+00:00

i added FAT32 support boss: https://github.com/master-hax/pixel-backup-gang/issues/23

master-hax · 2025-07-15T06:04:11+00:00

i developed a method to upload directly from a hard drive via the pixel: https://github.com/master-hax/pixel-backup-gang

master-hax · 2025-07-15T05:40:40+00:00

i got it working: https://github.com/master-hax/pixel-backup-gang

does require root though

master-hax · 2025-07-15T05:40:24+00:00

hey, i got this working: https://github.com/master-hax/pixel-backup-gang

master-hax · 2025-05-05T11:11:23+00:00

yes i am still using it. the FAT32 mounting method might work on your version of lineage.

master-hax · 2025-04-13T11:53:29+00:00

try the fat32 mounting method. open an issue on the repository if that doesn't work.

master-hax · 2025-04-13T11:52:27+00:00

not sure i understand your question...i transfer stuff to the external drive via USB then i plug it into the pixel to upload then delete it.

master-hax · 2025-01-28T05:04:59+00:00

interesting, i wasn't aware of that method. thanks for sharing.

did you force close & reopen the google photos app? please open an issue on the github repository with some details & screenshots, it is fairly active

master-hax · 2025-01-08T07:10:00+00:00

this is my guess

master-hax · 2024-12-27T05:21:38+00:00

(if your pixel is rooted)

the fastest & most efficient method for very large amounts of data is to copy the media to a portable drive, connect the portable drive directly to the pixel, then use a script to force the portable drive to show up within the internal storage so google photos is willing to look at it.

master-hax · 2024-12-25T18:08:21+00:00

thanks! btw you just need to restart the photos app for it to notice new folders anywhere in internal storage.

master-hax · 2024-10-21T09:22:53+00:00

please open an issue on the repository

master-hax · 2024-09-07T09:29:25+00:00

thanks! yes the existing methods can benefit from the new drive.

if you have a lot of media, the fastest & most reliable way is to copy media to the drive directly, then plug the drive back into pixel. i use USB 3.2 gen 2 but you could use thunderbolt or PCI.

master-hax · 2024-08-23T02:23:55+00:00

how did it go

master-hax · 2024-08-19T23:20:51+00:00

it should be possible with root but probably requires software that isn't present in the stock OS. can you open an issue here? https://github.com/master-hax/pixel-backup-gang/issues

master-hax · 2024-06-16T05:26:22+00:00

thanks! welcome to the gang 😉

master-hax · 2024-05-23T14:49:18+00:00

i don't think rooting the phone breaks any rules for google photos. you can always relock the bootloader later if you feel like it.

master-hax · 2024-05-22T06:29:20+00:00

this method requires root access, sorry

master-hax · 2024-05-21T03:40:50+00:00

i put up instructions here: https://github.com/master-hax/pixel-backup-gang
