Copy-pasting multiline (multiple lines) query into bean-query

[Dan Andersson]

Hi,

After doing bean-query foo.beancount to enter the interactive session, can I somehow copy-paste multiple lines in there?

It seems like multi-line queries (e.g. the examples in the documentation), when pasted in there, always get split into one command per line, resulting in errors.

Do I always have to combine those lines first, before pasting them?

Thanks,

DA

This is a bash question. Look at how multiple lines are handled in bash (should be lots of info online).

Hi, I'm aware that backslashes can be used for Bash.

I was referring to the interactive session (after doing only "bean-query foo.beancount"). I guess I was hoping it wouldn't "complete" a command until it sees a semicolon, but currently it seems to complete a command after every newline.

Motivation: Give people (including Windows users) copy-pasteable commands they can simply use as-is (regardless of platform).

I don't know. If it's supported in https://docs.python.org/3/library/cmd.html it should be possible to improve it.

I was not able to figure out how to do multi-line queries in interactive bean-query so I paste them into my beancount file and use fava to run them or run them with:

> bean-query <beancount file> run <query-name>

I did jot this down in my notes, but not sure if my notes are accurate:

- bean-query interactive uses the python gnu readline package (not to be confused with python library's readline)

This is not accurate: bean-query uses the readline Python standard
library module, which uses GNU readline on Linux, libedit on macOS, and
is not available on Window.

Multi-line input is not currently supported by bean-query. The
interactive interpreter is based on the cmd Python standard library
module, which is a line based command interpreter.

Using a semicolon as query terminator instead of a newline should be
possible (the Python REPL supports multi-line input statements, thus the
functionality is there, somewhere) but it would require moving from a
very simple REPL to something that uses a much more fancy parser.

I had investigating this on my TODO list for a long time, but I haven't
had the time to look into it yet.

Cheers,
Dan
