8 | 8 | """Generic output formatting for Mercurial |
|
9 | 9 | |
|
10 | 10 | The formatter provides API to show data in various ways. The following |
|
11 | 11 | functions should be used in place of ui.write(): |
|
12 | 12 | |
|
13 | 13 | - fm.write() for unconditional output |
|
14 | 14 | - fm.condwrite() to show some extra data conditionally in plain output |
|
15 | 15 | - fm.context() to provide changectx to template output |
|
16 | 16 | - fm.data() to provide extra data to JSON or template output |
|
17 | 17 | - fm.plain() to show raw text that isn't provided to JSON or template output |
|
18 | 18 | |
|
19 | 19 | To show structured data (e.g. date tuples, dicts, lists), apply fm.format*() |
|
20 | 20 | beforehand so the data is converted to the appropriate data type. Use |
|
21 | 21 | fm.isplain() if you need to convert or format data conditionally which isn't |
|
22 | 22 | supported by the formatter API. |
|
23 | 23 | |
|
24 | 24 | To build nested structure (i.e. a list of dicts), use fm.nested(). |
|
25 | 25 | |
|
26 | 26 | See also https://www.mercurial-scm.org/wiki/GenericTemplatingPlan |
|
27 | 27 | |
|
28 | 28 | fm.condwrite() vs 'if cond:': |
|
29 | 29 | |
|
30 | 30 | In most cases, use fm.condwrite() so users can selectively show the data |
|
31 | 31 | in template output. If it's costly to build data, use plain 'if cond:' with |
|
32 | 32 | fm.write(). |
|
33 | 33 | |
|
34 | 34 | fm.nested() vs fm.formatdict() (or fm.formatlist()): |
|
35 | 35 | |
|
36 | 36 | fm.nested() should be used to form a tree structure (a list of dicts of |
|
37 | 37 | lists of dicts...) which can be accessed through template keywords, e.g. |
|
38 | 38 | "{foo % "{bar % {...}} {baz % {...}}"}". On the other hand, fm.formatdict() |
|
39 | 39 | exports a dict-type object to template, which can be accessed by e.g. |
|
40 | 40 | "{get(foo, key)}" function. |
|
41 | 41 | |
|
42 | 42 | Doctest helper: |
|
43 | 43 | |
|
44 | 44 | >>> def show(fn, verbose=False, **opts): |
|
45 | 45 | ... import sys |
|
46 | 46 | ... from . import ui as uimod |
|
47 | 47 | ... ui = uimod.ui() |
|
48 | 48 | ... ui.verbose = verbose |
|
49 | 49 | ... ui.pushbuffer() |
|
50 | 50 | ... try: |
|
51 | 51 | ... return fn(ui, ui.formatter(pycompat.sysbytes(fn.__name__), |
|
52 | 52 | ... pycompat.byteskwargs(opts))) |
|
53 | 53 | ... finally: |
|
54 | 54 | ... print(pycompat.sysstr(ui.popbuffer()), end='') |
|
55 | 55 | |
|
56 | 56 | Basic example: |
|
57 | 57 | |
|
58 | 58 | >>> def files(ui, fm): |
|
59 | 59 | ... files = [(b'foo', 123, (0, 0)), (b'bar', 456, (1, 0))] |
|
60 | 60 | ... for f in files: |
|
61 | 61 | ... fm.startitem() |
|
62 | 62 | ... fm.write(b'path', b'%s', f[0]) |
|
63 | 63 | ... fm.condwrite(ui.verbose, b'date', b' %s', |
|
64 | 64 | ... fm.formatdate(f[2], b'%Y-%m-%d %H:%M:%S')) |
|
65 | 65 | ... fm.data(size=f[1]) |
|
66 | 66 | ... fm.plain(b'\\n') |
|
67 | 67 | ... fm.end() |
|
68 | 68 | >>> show(files) |
|
69 | 69 | foo |
|
70 | 70 | bar |
|
71 | 71 | >>> show(files, verbose=True) |
|
72 | 72 | foo 1970-01-01 00:00:00 |
|
73 | 73 | bar 1970-01-01 00:00:01 |
|
74 | 74 | >>> show(files, template=b'json') |
|
75 | 75 | [ |
|
76 | 76 | { |
|
77 | 77 | "date": [0, 0], |
|
78 | 78 | "path": "foo", |
|
79 | 79 | "size": 123 |
|
80 | 80 | }, |
|
81 | 81 | { |
|
82 | 82 | "date": [1, 0], |
|
83 | 83 | "path": "bar", |
|
84 | 84 | "size": 456 |
|
85 | 85 | } |
|
86 | 86 | ] |
|
87 | 87 | >>> show(files, template=b'path: {path}\\ndate: {date|rfc3339date}\\n') |
|
88 | 88 | path: foo |
|
89 | 89 | date: 1970-01-01T00:00:00+00:00 |
|
90 | 90 | path: bar |
|
91 | 91 | date: 1970-01-01T00:00:01+00:00 |
|
92 | 92 | |
|
93 | 93 | Nested example: |
|
94 | 94 | |
|
95 | 95 | >>> def subrepos(ui, fm): |
|
96 | 96 | ... fm.startitem() |
|
97 | 97 | ... fm.write(b'reponame', b'[%s]\\n', b'baz') |
|
98 | 98 | ... files(ui, fm.nested(b'files', tmpl=b'{reponame}')) |
|
99 | 99 | ... fm.end() |
|
100 | 100 | >>> show(subrepos) |
|
101 | 101 | [baz] |
|
102 | 102 | foo |
|
103 | 103 | bar |
|
104 | 104 | >>> show(subrepos, template=b'{reponame}: {join(files % "{path}", ", ")}\\n') |
|
105 | 105 | baz: foo, bar |
