Work with buffer (not file)

[remche]

It would be great if jqx could work with the buffer. My use case is to use with vim-rest-console. It would need following options :

• [ ] allow to specify custom file type in populate_qf (or all ft) ;
• [ ] don't always use local file in https://github.com/gennaro-tedesco/nvim-jqx/blob/6e179064b580795770a4bf0c10d19ea53fd27357/lua/nvim-jqx/jqx.lua#L54
• [ ] allow to run JqxQuery on the buffer instead of current_file

Thx for the great work !

Could you please elaborate a little on your request, so that I could understand better?

jqx could work with the buffer

what do you have in mind here? An empty buffer or a buffer populated with some text and no filetype specified (I suspect the latter)?

In general the reason why I explicitly pass the filetype is to ensure that jqx acts properly on json or yaml by calling jq or yq, respectively. Both of them need the filename to be explicitly passed to the query in order to produce results, as their grammar is something along the lines of jq <query> <filename>. If I understand correctly, however, you would like that - in case the filetype is unset (for the sake of simplicity let us consider this case first) - the queries are run by considering the content of the buffer as input for the standard input?

That's it: I use diepm/vim-rest-console that allow to send REST requet and display answer on a buffer.

jq and yq both an work with standard input, I use them almost everyday this way ;)

For instance : https://github.com/remche/terraform-openstack-rke2/blob/73b0018fda817b666ef226ead84c934b4f81dc46/modules/node/files/cloud-init.yml.tpl#L21

Yes. I bet there will be a problem to know if we should use jq or yq is the ft is not set. As YAML is a superset of JSON, may be falling to yq is the way to handle that case ?

Thank you for clarifying. One thing that could be a "quick win" would be to introduce a condition such that, if the filename is null (namely the buffer isn't saved to a file but only temporarily filled with data) and the filetype is still set correctly to either json or yaml, then I could execute the query using the buffer text as standard input. I would have to check if this however breaks the query on keystrokes or JqxQuery in general.

I will have a look over the weekend and test possible solutions :)

An update on this issue: I tried a few different solutions but have not yet found one that would not conflict with some parts of the plugin (or make the usage/code quite more cumbersome): I will continue looking into it.
