29 # Let's use 128 char width. |
|
30 # It is silly to stick to the 80-char rule. |
|
31 # |
|
32 # |
|
33 # Terminologies <== Read before you got confused |
|
34 # - branch type |
|
35 # We distinguish the following types of branches: master, develop, feature, release, hotfix, support. |
|
36 # We should assume any branch is of one of these types. |
|
37 # |
|
38 # - stream |
|
39 # The entire set of branches of the same type. Stream is not branch, it is a set. Stream is not a type, it is a set. |
|
40 # Stream is a set of branches. |
|
41 # |
|
42 # - substream |
|
43 # A subset of branches in a stream. |
|
44 # |
|
45 # - trunk |
|
46 # Trunk is a special branch. A stream can optionally have a trunk, but only one trunk at most. For example, master and |
|
47 # develop streams each has a trunk, whereas feature, release, hotfix, and support streams don't. |
|
48 # If a stream has a trunk, all branches in the stream normally should diverge from the trunk and later merge to the trunk |
|
49 # when the branches are closed. |
|
50 # Trunk is a relative concept. A trunk of a stream may be a regular branch of another stream. (The former stream will be |
|
51 # a substream of the latter.) |
|
52 # |
|
53 # - source |
|
54 # Source is an attribute of stream. The source of a stream refers to the parent stream where branches in the current stream |
|
55 # are created from. Most commonly, source of a stream is the stream itself. But this is not always the case, for example, |
|
56 # the sources of release and feature streams are the develop stream. |
|
57 # |
|
58 # - destin |
|
59 # Destin is another attribute of stream. The destin of a stream refers to the stream(s) where branches in the current |
|
60 # stream will merge to. Most commonly, destin of a stream is the stream itself. But this is not always the case, for |
|
61 # example, the destin of release is the develop and the master streams. |
|
62 # |
|
63 # - branch name |
|
64 # Use this term carefully since it is potentially ambiguious. |
|
65 # Try using this term to refer to fullname (see below). |
|
66 # |
|
67 # - fullname |
|
68 # Branch name as recognized by the SCM, e.g., feature/enhance_log. |
|
69 # Prefer this term to 'branch name'. |
|
70 # |
|
71 # - basename |
|
72 # Branch name recognized by flow, but not necessarily by SCM, e.g., enhanced_log (with prefix 'feature/' dropped). |
|
73 # |
|
74 # - name |
|
75 # Use this term carefully since it is potentially ambiguious. |
|
76 # This term should be a synonym of basename (see above). Try using it only as place holders, such as |
|
77 # <hotfix-prefix>/<name>. |
|
78 # |
|
79 # - flow action |
|
80 # Refer to action on a specified stream, e.g., hg flow feature start, where 'start' is an action. |
|
81 # |
|
82 # - flow command |
|
83 # Refer to other actions than those on a stream, e.g., hg flow unshelve, where 'unshelve' is a command. |
|
84 # |
|
85 # - hg command |
|
86 # Refer to command not from flow extension. |
|
87 # |
|
88 # - workflow |
|
89 # Refer to the process of executing a sequence of hg commands. |
|
90 # |
|
91 # - history |
|
92 # Refer to a sequence of hg commands that has been executed. |
|
93 # |
|
94 # Notations |
|
95 # - <stream> |
|
96 # Examples: <feature>, <hotfix>. These denote the corresponding streams. When you refer to a stream, e.g., feature stream, |
|
97 # use '<feature>' (or more verbosely 'feature stream'), instead of '<feature> stream', because '<feature>' already means |
|
98 # stream. |
|
99 # |
|
100 # - <stream> branch |
|
101 # Example: a <feature> branch. This phrase refers a branch in <feature>. Do not use 'a feature branch' to mean a branch in |
|
102 # <feature> because the word 'feature' there should take its usual meaning as in English, which doesn't necessarily mean |
|
103 # the feature stream. |
|
104 # |
|
105 # - `text` |
|
106 # Example, `hg flow feature start <name>`. The text wrapped by the ` (apostrophe) symbols should be a piece of code or |
|
107 # shell command, which could contain placeholders to be replaced by actual values. |
|
108 # |
|
109 # - 'text' or "text" |
|
110 # Refer to an exact string. |

|
2662 Concepts: |
|
2663 - stream |
|
2664 The entire set of branches of the same type. Stream is not branch, it is a |
|
2665 set of branches. In general, a stream can contain any number (including zero) |
|
2666 of branches. The master stream is, however, special in that it contains 1 and |
|
2667 only 1 branch. The develop stream contains at least one branch. |
|
2668 |
|
2669 - basic streams |
|
2670 Refers to the master, develop, feature, release, hotfix, and support streams |
|
2671 as predefined in Driessen's model. |
|
2672 |
|
2673 - natural streams |
|
2674 Refers to a set of branches that diverged from and will merge into the same |
|
2675 branch. The set of branches plus the branch that they diverged from form a |
|
2676 natural stream. The branch that all the other branches in the same natural |
|
2677 stream diverged from and will merge into is the trunk of the natural stream. |
|
2678 |
|
2679 - trunk |
|
2680 Trunk is a special branch. A stream can optionally have a trunk, but only one |
|
2681 trunk at most. For example, master and develop streams each has a trunk, |
|
2682 whereas feature, release, hotfix, and support streams don't. And all natural |
|
2683 streams each has a trunk. If a stream has a trunk, all branches in the stream |
|
2684 normally should diverge from the trunk and later merge to the trunk when they |
|
2685 are finished. |
|
2686 Trunk is a relative concept. A trunk of a stream may be a regular branch of |
|
2687 another stream. (The former stream will be called a substream of the latter.) |
|
2688 |
|
2689 - source |
|
2690 Source is an attribute of stream. The source of a stream refers to the stream |
|
2691 where branches in the current stream are created from. A stream's source can |
|
2692 be the stream itself. But this is not always the case, for example, |
|
2693 the sources of release and feature streams are the develop stream. |
|
2694 |
|
2695 - destin |
|
2696 Destin is another attribute of stream. The destin of a stream refers to the |
|
2697 stream(s) where branches in the current stream will merge to. A stream's |
|
2698 destin can be the stream itself. But this is not always the case, |
|
2699 for example, the destin of release is the develop and the master streams. |
|
2700 |
|
2701 - fullname |
|
2702 Branch name as recognized by the SCM, e.g., feature/enhance_log. |
|
2703 |
|
2704 - basename |
|
2705 Branch name recognized by flow, but not necessarily by SCM, e.g., |
|
2706 enhanced_log (with prefix 'feature/' dropped). |
|
2707 |
|
2708 - flow action |
|
2709 Refer to action on a specified stream, e.g., hg flow feature start, where |
|
2710 'start' is an action. |
|
2711 |
|
2712 - flow command |
|
2713 Commands don't act on a stream, e.g., hg flow unshelve, where 'unshelve' |
|
2714 is a command. |
|
2715 |
|
2716 - hg command |
|
2717 Refer to commands not from flow extension. |
|
2718 |
|
2719 - workflow |
|
2720 Refer to the process of executing a sequence of hg commands. |
|
2721 |
|
2722 - history |
|
2723 Refer to a sequence of executed hg commands. |
|
2724 |
|
2725 Notations |
|
2726 - <stream> |
|
2727 Examples: <feature>, <hotfix>. These denote the corresponding streams. When |
|
2728 you refer to a stream, e.g., feature stream, use '<feature>' (or more |
|
2729 verbosely 'feature stream'), instead of '<feature> stream', because |
|
2730 '<feature>' already means stream. |
|
2731 |
|
2732 - <stream> branch |
|
2733 Example: a <feature> branch. This phrase refers a branch in <feature>. Do not |
|
2734 use 'a feature branch' to mean a branch in <feature> because the word |
|
2735 'feature' there should take its usual meaning as in English, which doesn't |
|
2736 necessarily mean the feature stream. |
