Mercurial log with one-liners

Question

The regular hg log command gives output with at least 4 lines per changeset. For example

changeset:   238:03a214f2a1cf
user:        My Name 

        

Answer 1

To get the description on one line even if original comment contains multiple line combine a splitlines and join function like below:

{join(splitlines(desc), ' ')}

Here is an example i'm using to extract data as CSV:

hg log --template "{node};{date|shortdate};{branch};{author};{join(splitlines(desc), ' ')};{diffstat};files: {join(files, ', ')}\n"
