How to get modified files list along with their revision in hg log in Mercurial?

Question

My idea is, starting from a repo with multiple revs, to obtain the list of revisions, along with the {matching-file-patterns} that have changed in each of them.

The objective is, with that data, to obtain the number of times each .CPP and .H file has changed, and additional data as date, user who changed the file, ... to track more thoroughly the progress of the project.

hg log --template "revision:{rev}\nfiles:\n{files % '  {file}\n'}"

The above will accomplish partially my claim (along with piping the output to a .txt file and parsing it externally), but I still find interesting to pre-filter the results, this is, that the hg log only shows .CPP and .H files, for example.

I have looked into it, and the option "set: * .cpp or * .h" would do, but

hg log "set: **.cpp or **.h" --template "revision:{rev}\nfiles:\n{files % '  {file}\n'}"

will not make filtering of any type.

Any advice/solution is welcome in this task, even in the main task which is to automate the report! (I am totally sure there is an easier way to accomplish it)

Thank you.

Answer 1

1. Use revsets, not filesets in log command
2. Use simpler template: your template output nothing in my tests (after relevant editing of conditions), but --template "{rev} {author}\\n" show list of revisions

Revset will be -r "file('**.cpp') + file('**.h')"

Edit

Implemented log with fileset, for my repo and files

>hg log "set: **.txt or **.png" --template "{rev}:{node|short} {author|user} {date|isodate}\n{files % '  {file}\n'"

For some reason construction \\nfiles:\\n{files % ' {file}\\n' didn't not work, but without static text can be used.

Pay attention to filelists for changesets - they include all types of files, not only needed types
