zsv playground

[iamazeem]

• Separate job for wasm build
• Separate job for deploying wasm build to GitHub Pages
• Fix compiler warnings
• Fix test coloring issue (replace echo -e with printf)
• Ignore generated files
• Add support for stdin
  • not feasible to handle generically both for csv input and command line prompting
• Add support for adding files
• Test
  • With multiple browsers e.g. chrome, firefox, etc.
  • Make sure the cache is disabled during testing to avoid any surprises and/or side effects later
• Update README

Other misc updates:

• Use NO_THREADING to skip -pthread flag
• Use NO_STDIN to disable stdin input for consistency
• Introduce NO_PLAYGROUND CLI flag for conditional switching of flags and main function name for playground and the rest

Resolves #161

TODOs:

• Verify deployment after merge to main
• Fix issues if any

@liquidaty:
Going for a terminal style playground.
It seems more natural for a CLI app and there'll be no learning curve.

Here's an initial preview of the playground in the browser:

Targeting the basic functionality for an initial release.
Please do share your feedback on this.
Any specific features that should be in the initial release?

Sounds good. Is it possible to run sheet in the playground? I am guessing it is not possible, but if it was, that would be very cool. I have seen a wasm build for ncurses, but have no idea whether there is any way to make it work on a web page.

Initially, I started looking for something that could enable sheet as well but found nothing promising.
Most of the examples were using a client/server model using SSH to display n/curses TUIs.

I have seen a wasm build for ncurses, but have no idea whether there is any way to make it work on a web page.

Is this the one?

@liquidaty: Please review. Thanks!

You may test the latest build locally from https://github.com/liquidaty/zsv/actions/runs/11995887192.

• Download github-pages artifact (https://github.com/liquidaty/zsv/actions/runs/11995887192/artifacts/2229557270).
• Extract it and its nested archive too.
• From terminal, cd to its path.
• Start an HTTP static file server e.g. npx serve --cors.
• Click on the local URL e.g. http://localhost:3000.

Here's the latest demo on firefox:

@iamazeem this is great! Just two suggestions for now:

• add "rm" command-- this can simply be an alias for "zsv rm"
• add some sort of filename autocomplete when "tab" is entered. This does not have to be sophisticated; the main thing here is to make it easy to enter a file name into the command line, without having to exactly remember what the file name was

[liquidaty]

Two more!

• add a "save" command to download a file
• add a "wipe" command (maybe there is a better name for it?) to wipe out all saved data. Maybe also offer to do this when the web page is unloaded?

Could you please elaborate this a bit?
IIUC, the FS data is automatically deleted when the tab is closed.

@liquidaty: Here's the demo with the latest changes (save, rm, and TAB autocompletion):

Workflow run: https://github.com/liquidaty/zsv/actions/runs/12004676940
GitHub Pages artifact: https://github.com/liquidaty/zsv/actions/runs/12004676940/artifacts/2231345890

Demo:

Regarding wipe command, rm supports multiple arguments.
That should serve the purpose of removing multiple files if that's what you meant earlier.

Fixed the flushing issue in bf144bd.
The zsv_writer_delete seemed the right place to do it.

Please review the PR again. Thanks!

PS:
Observed an issue with zsv flatten command. See #303.

[iamazeem]

@liquidaty: Please review and test on your side.
The TAB autocompletion has also been implemented for zsv commands and flags.
