5.4 Examining Your Changes

(prev) (next)

Generally speaking, the reason to form your own branches is to to development: you commit your changes to your branches; others (usually upstream) can merge those changes from your branches.

Hypothetical Local Changes, For Illustration Purposes

Begin with a tree containing a revision of your branch:

    % tla get lord@gnu.org--my-hacks-2005/TOP--tla--1.3.1 tla-tree
    % cd tla-tree
    % tla buildcfg ./config
    % cd src/tla
    % tla tree-version
    lord@emf.net--my-hacks-2005/TOP--tla--1.3.1

  

In that directory, make your changes to the tla project.

As an example, let's suppose that you make two changes. First, you modify the file COPYING so that instead of beginning:

from Copying:

    All or most of the source files in this distribution refer to this
    file for copyright and warranty information.  This file should be
    included whenever those files are redistributed.

  

it begins:

from (modified) Copying:

    All or most of the source files in the tree rooted here refer to this
    file for copyright and warranty information.  This file should be
    included whenever those files are redistributed.

  

You might also add a comment to Makefile.in so that instead of:

from Makefile.in:

    include $(makefiles)/dirs.mk

  

it reads

from Makefile.in:

    # use the default rules for recursively building
    # a set of subdirectories, in the appropriate order:
    # 
    include $(makefiles)/dirs.mk

  

Examining Changes

The command

    % tla changes 

  

reports the list of modified files.

With an option:

    % tla changes --diffs

  

reports both the list of modified files and diffs of how those files have changed.

Commands Discussed

    % tla changes -H
