14 # parseseq.pl [<arguments>] <sequence file> |
|
15 # Arguments: |
|
16 # -p Include popups (when clicking on messages etc). |
|
17 # -r <begin row>,<end row> Display rows in the range specified. Row numbers are zero based and inclusive. |
|
18 # Negative row numbers count backwards from the end row. <begin row> and/or |
|
19 # <end row> may be omitted, in which case the beginning and ending rows respectively |
|
20 # are assumed. If "r" argument is not specified, a default of the last 400 rows |
|
21 # is assumed (equivalent to an argument of "-r -400,"). |
|
22 # -R <rows per view> The maximum number of rows in each "view" (page). The overall sequence is generated as a number |
|
23 # of individual HTML/SVG files, each showing a fragment of the sequence. Each of these is |
|
24 # termed a "view". This option indicates the maximum number of rows per view. Note |
|
25 # that because the sequence is split into equal sized views, the actual size of each |
|
26 # view can vary from half values of this parameter to its full value. This parameter |
|
27 # only limits the maximum size of each view. |
|
28 # -H On "trimmed" displays (i.e. only displaying last <n> lines), don't |
|
29 # hide object timelines that don't have any messages within the area |
|
30 # being displayed (but do have messages outside of that area). |
|
31 # -x <file> File containing "[DontHideShortName]" section which contains truncated names |
|
32 # of classes (minus the instance numbering at the end) that should *not* be |
|
33 # hidden from "trimmed" displays (i.e. displays where only the last <n> lines |
|
34 # are displayed). |
|
35 # -M Exclude messages from the display. Used for getting an overview of node and activity creation. |
|
36 # -v Print on standard output a list of objects which have not been displayed because |
|
37 # they exchanged no messages or were outside of the displayed view. |
|
38 # -V Print on standard output some progress messages (useful when parsing long logs that |
|
39 # take several minutes). |
|
40 # -f Do not display page links in a fixed position window. |

68 Arguments: |
|
69 |
|
70 -p Include popups (when clicking on messages etc). |
|
71 |
|
72 -r <begin row>,<end row> Display rows in the range specified. Row numbers are zero based and inclusive. |
|
73 Negative row numbers count backwards from the end row. <begin row> and/or |
|
74 <end row> may be omitted, in which case the beginning and ending rows respectively |
|
75 are assumed. If "r" argument is not specified, a default of the last 400 rows |
|
76 is assumed (equivalent to an argument of "-r -400,"). |
|
77 |
|
78 -R <rows per view> The maximum number of rows in each "view" (page). The overall sequence is generated |
|
79 as a number of individual HTML/SVG files, each showing a fragment of the sequence. |
|
80 Each of these is termed a "view". This option indicates the maximum number of rows |
|
81 per view. Note that because the sequence is split into equal sized views, the actual |
|
82 size of each view can vary from half values of this parameter to its full value. |
|
83 This parameter only limits the maximum size of each view. |
|
84 |
|
85 -H On "trimmed" displays (i.e. only displaying last <n> lines), don't |
|
86 hide object timelines that don't have any messages within the area |
|
87 being displayed (but do have messages outside of that area). |
|
88 |
|
89 -x <file> File containing "[DontHideShortName]" section which contains truncated names |
|
90 of classes (minus the instance numbering at the end) that should *not* be |
|
91 hidden from "trimmed" displays (i.e. displays where only the last <n> lines |
|
92 are displayed). |
|
93 |
|
94 -M Exclude messages from the display. Used for getting an overview of node and activity |
|
95 creation. |
|
96 |
|
97 -v Print on standard output a list of objects which have not been displayed because |
|
98 they exchanged no messages or were outside of the displayed view. |
|
99 |
|
100 -V Print on standard output some progress messages (useful when parsing long logs that |
|
101 take several minutes). |
|
102 |
|
103 -f Do not display page links in a fixed position window. |
|
104 |
|
105 -n Print node names vertically as opposed to horizontally. |
|
106 |
|
107 -N Node to filter available list by. If set, you will be given a list of node activities |
|
108 which contain the string you passed in, in the node. Select one of these and it will |
|
109 generate the diagram only for the lifetime of that activity. |
|
110 |
|
111 -A Activity to filter available list by. If set, you will be given a list of node |
|
112 activities which match the string you passed in, in the activity. |
