in ledger-mode, color posting account names based on initial substring

[d3rsh...@gmail.com]

Hello there, I've just started to work with ledger a week ago and am now switching to emacs for a couple of reasons.

For my personal ledger workflow, there are two things I would like to acheive, the first one of which I'm addressing in this topic.

--------------------

How can I adjust ledger-mode syntax highlighting such that a posting's account name is colored differently depending on an initial substring? I put all accounts either under "Assets:", "Equity:", "Liabilities:", or "Budgets:" and would love to see each of these four groups being colored differently while I work on the file.

I already found ledger-fonts.el and tried to replace ,ledger-posting-regex near the end of the file by my own regexes, but it seems to have no effect. Even if I comment out this part, syntax highlighting stays the same. Do I still need to update the emacs settings somehow? And is there maybe a "cleaner" way to acheive this? As I'm really new to emacs and elisp, I'm not sure how I can do this best.

Any help is greatly appreciated!
