top2bottom is a command-line tool that converts top-posted email messages to bottom-posted.
To build top2bottom you need:
- the meson build system
- a C++14 compiler
Building and installing
top2bottom uses the meson build system.
To configure top2bottom use:
$ meson build
This will create a top2bottom build configuration in the build directory.
To see/set the full list of available options use:
$ mesonconf [-Dopt=val] build
To build use:
$ ninja -C build
To install use:
$ [DESTDIR=...] ninja -C build install
Run the tests with:
$ ninja -C build test
You can run top2bottom with:
$ /path/to/top2bottom < top-posted-file [> bottom-posted-file]
Supported top-posting flavor
top2bottom supports a particular flavor of top-posted messages that looks like:
aaa B wrote: > bbb > > C wrote: >> >> ccc
top2bottom also supports conversion of messages which were originally bottom-posted or interleaved-posted but at some point continued as top-posted:
aaa B wrote: > C wrote: >> >> ccc > bbb >> ccc > > bbb
Messages that are already properly bottom-posted or interleaved-posted are returned unchanged.
If top2bottom cannot convert a message, then it returns the message unchanged in stdout, and a warning with information about which line caused the conversion to fail in stderr.
