Wish: being able to specify the target year and input journal directory on the command-line

[lestephane]

I'd like to use the export.hs script as-is because I don't want to diverge from this repo's version, but find myself having to modify it for my specific environment. Would it be possible to have these two variables specifiable using command-line arguments on the export.hs command-line?

• current year (to export up to)
• input journal directory path (.. is not helpful in my case, as all the files need to be in the same directory, and the parent directory is already called export)

$ git diff
diff --git a/01-getting-started/export/export.hs b/01-getting-started/export/export.hs

My current workaround is to symlink export.sh into my export directory, patch it using sed, and invoke the patch version:

#!/bin/bash
# source: https://github.com/adept/full-fledged-hledger/tree/master/01-getting-started/export

my_dir=$(dirname $(readlink -e "$0"))

sed \
    -e 's/^input y.*/input y = printf "%s.journal" y/' \
    -e "s/^current = .*/current = $(date -d "last year" +%Y)/" \
        "${my_dir}/export.hs" > "${my_dir}/patched-export.hs"

"${my_dir}/patched-export.hs" -j --color "$@"

I've pushed changes that add --first, --current and --base (run export.sh --help to see the format).

Works for me, thanks!

"export.hs" --base=$(pwd) --first=2017 --current="$(date -d "last year" +%Y)"
