top: add a flexible 'Inspect' capability
This commit introduces an extremely powerful, flexible
brand new capability. Now, users can pause the normal
iterative display and inspect the contents of any file
or output from any script, command, or even pipelines.
It's invoked via the 'Y' interactive command which, in
turn, is supported with simple user supplied additions
as new entries in the top personal configuration file.
A separate new 'Inspect' window supports scrolling and
searching, similar to the main top display. Except it
extends existing 'L'/'&' (locate/locate-next) commands
so that an out-of-view match automatically adjusts the
horizontal position bringing such data into view. And
it provides for multiple successive same line matches.
Also, the basic 'more/less' navigation keys are active
in this new 'Inspect' window, to ease user transition.
There are no program changes required when entries are
added to or deleted from the rcfile. And there are no
known limits to the complexity of a script, command or
pipeline, other than the unidirectional nature imposed
by the 'popen' function call which top cannot violate.
Since it's impossible to predict exactly what contents
will be generated, top treats all output as raw binary
data. Any control characters display in '^C' notation
while all other unprintable characters show as '<AB>'.
The biggest problem encountered was with the find/next
capability since that strstr guy was really diminished
given the possibility that numerous 'strings' could be
encountered *within* many of top's raw, binary 'rows'.
Oh, and another problem was in maintaining the perfect
left & right text justification of this commit message
along with all of the commit summaries. Some of those
summaries (like this very one) are of course, slightly
shorter, to make room for the 'man document' addition.
Enjoy!

top: refactor 'scale_tics' function for better scaling
This patch refactors the 'scale_tics' function to more
closely parallel uptime shown on the first line of the
summary area. The old logic has been preserved through
the header file's new #define SCALE_FORMER provision.
However, the former logic was actually a big disaster.
These are some potential problems with that old logic:
1. With respect to our time fields top no longer deals
solely with cpu time. So, the old limits of '68 weeks'
could possibly be insufficient to reflect those times.
2. Given the widths of top's new time fields, the code
never got beyond scaling to hours. For example, with a
ridiculously large span of 19 years, the scaled result
would then be shown as '167832h'. We never reached the
days ('6993d') or even the weeks ('999w') equivalents.
3. Similarly, with that 'TIME+' field and a large tics
value, results would then appear as 'MMMMMM:SS' rather
than the more meaningful 'HH:MM:SS' or days and hours.
So henceforth we will adopt these scaling conventions:
MMM:SS.hh ... minutes:seconds.hundredths
MMM:SS ...... minutes:seconds
HH,MM ....... hours,minutes
D+H ......... days+hours (with 'd' & 'h' suffixes)
D ........... days (with 'd' suffix)
W+D ......... weeks+days (with 'w' & 'd' suffixes)
W ........... weeks (with 'w' suffix)
Note that, unlike our former scaling logic, that 'MMM'
portion won't be allowed to grow unconditionally. It's
limited (arbitrarily?) to 360 total minutes (6 hours).
Additionally, the 'HH' guy will be limited to 96 hours
(4 days) while that 'D' limit was set at 14 (2 weeks).
Whenever a limit is hit, scaling will advance a level.

top: parent total cpu includes collapsed children, pgm
Now, when a parent's children have been collapsed, the
cpu used by those unseen tasks will disappear no more.
Instead such tics will be added to the parent's total.
[ if one wished a return to the 'land of lost tics', ]
[ the '#define TREE_VCPUOFF' directive is available. ]
------------------------------------------------------
Note: With collapsible parents now displaying children
cpu usage, it will eventually be noticed the cpu stats
for the summary area and task areas often vary widely.
It's worth a reminder that for top's summary area each
individual cpu and the cpu summary is limited to 100%,
regardless of how many tics a linux kernel may export.
An individual task is limited to 100% times the number
of threads. But, in no case will cpu usage ever exceed
100% times total number of processors. Such limits are
further reduced under 'Solaris' mode ('I' toggle off).
In this mode, a task cpu usage will never exceed 100%.
These limits will now also apply to collapsed parents.
In addition to those influences, results are subjected
to kernel timer sampling anomalies and the distortions
inherent in a small sample size, made worse by smaller
delay intervals. Often there is just 1 or 2 tics for a
few tasks at smaller intervals such as: 1/10th second.
Anyway, should questions on this subject arise, a good
starting point, beyond the reminders above, is the 1st
link listed below. Those other links were derivatives.

top: add a flexible 'Inspect' capability
This commit introduces an extremely powerful, flexible
brand new capability. Now, users can pause the normal
iterative display and inspect the contents of any file
or output from any script, command, or even pipelines.
It's invoked via the 'Y' interactive command which, in
turn, is supported with simple user supplied additions
as new entries in the top personal configuration file.
A separate new 'Inspect' window supports scrolling and
searching, similar to the main top display. Except it
extends existing 'L'/'&' (locate/locate-next) commands
so that an out-of-view match automatically adjusts the
horizontal position bringing such data into view. And
it provides for multiple successive same line matches.
Also, the basic 'more/less' navigation keys are active
in this new 'Inspect' window, to ease user transition.
There are no program changes required when entries are
added to or deleted from the rcfile. And there are no
known limits to the complexity of a script, command or
pipeline, other than the unidirectional nature imposed
by the 'popen' function call which top cannot violate.
Since it's impossible to predict exactly what contents
will be generated, top treats all output as raw binary
data. Any control characters display in '^C' notation
while all other unprintable characters show as '<AB>'.
The biggest problem encountered was with the find/next
capability since that strstr guy was really diminished
given the possibility that numerous 'strings' could be
encountered *within* many of top's raw, binary 'rows'.
Oh, and another problem was in maintaining the perfect
left & right text justification of this commit message
along with all of the commit summaries. Some of those
summaries (like this very one) are of course, slightly
shorter, to make room for the 'man document' addition.
Enjoy!

top: highlight all regular search string(s) when found
With the recent inspect search highlight provisions in
place, the lack of highlighting in task based searches
has grown from being only irritating to a real defect.
Thus, this commit introduces parallel functionality to
those searches initiated within a visible task window.
And just as separate inspect searches are possible for
each selection, per window task searches are provided.
However, it should be noted that there are differences
between task based searches and inspect type searches:
* There is no concept of out-of-view data when dealing
. with task rows -- if the data can't bee seen, it has
. not, in fact, been constructed from a proc_t struct.
* While inspect data is output at the character level,
. up to now all task display data was only potentially
. output and it was always based on a complete string.
* With task search highlighting, rows now containing a
. match must be output in pieces and, therefore, can't
. be optimized away like other rows which haven't been
. been altered. This is because top cannot predict the
. the contents of a search string or, how many matches
. might occur in a given row. Short search strings and
. many matches would raise buffer needs geometrically.
(now that we know a '.' + 2 spaces is squeezed to one)
(everything's perfectly justified, but it's just luck)

top: provide the means to adjust scaled process memory
This commit is an unrequested outgrowth of the earlier
change dealing with summary area memory field scaling.
That user selectable scaling provision is now extended
to include 6 (at present) task oriented memory fields.
The new companion 'e' (lower case) interactive command
has been added and, like the 'E' command, it can cycle
each of the currently displayed memory columns between
KiB through TiB. There are, however, some differences.
Where '+' indicates summary area truncation at a given
radix, task memory fields are automatically scaled for
their column. Thus, not all rows use the same scaling.
And, while summary area field widths were not changed,
the task memory columns were widened in order to offer
more meaningful data when the radix was increased. The
precision is automatically increased in step with each
radix: MiB displays 2 decimal places, GiB 3 and TiB 4.
To compliment that additional precision, both the %CPU
and %MEM fields were widened by 1 column and now offer
precision up to 3 decimal places. But, unique to %CPU,
widening could already have occurred due to the number
of processors in some massively parallel boxes. At any
rate, total extra width for both memory and percentage
fields could amount to twenty (precious) columns more.
So for both the memory and % fields the original width
(along with loss of precision) can be restored via new
compiler conditionals which this commit also provides.
p.s. and it will be rcfile preserved for any restarts!
(now that we know a '.' + 2 spaces is squeezed to one)
(everything's perfectly justified, but it's just luck)

top: provide an unlimited capacity for field additions
With each of those references shown below, the maximum
number of fields was increased. However, with a 'char'
based implementation we're nearing the upper limits of
total displayable fields. We currently use 76 of a max
of 86 fields. With extra effort, 94 might be possible.
But 94 is the absolute upper limit of possible fields!
Moreover, the current implementation yields characters
that were unprintable in the rcfile. This could become
an issue with that 'inspect' feature when/if an rcfile
is edited to add entries (as opposed to using 'echo').
So, with this commit the internals of field management
has been completely reimagined. It is now based on the
integer type, not a character. And whereas that former
design used the high order bit to show the 'on' state,
thus yielding an unprintable character, the new design
uses the low order bit for the state. As such, numbers
will be kept small and an even number will be an 'off'
field whereas an odd number will become an 'on' state.
The bottom line is that this new design will afford an
unlimited number of new fields while keeping an rcfile
completely free of that potential unprintable garbage.
And it is embarrassingly easy to extend the maximum of
supportable fields from the currently implemented 100.
Who knows, maybe a future patch will prove this point.
[ unless a subsequent commit proves otherwise, given ]
[ the dramatic differences in rcfile contents, i had ]
[ to abandon the practice of supporting old rcfiles. ]

top: provide an unlimited capacity for field additions
With each of those references shown below, the maximum
number of fields was increased. However, with a 'char'
based implementation we're nearing the upper limits of
total displayable fields. We currently use 76 of a max
of 86 fields. With extra effort, 94 might be possible.
But 94 is the absolute upper limit of possible fields!
Moreover, the current implementation yields characters
that were unprintable in the rcfile. This could become
an issue with that 'inspect' feature when/if an rcfile
is edited to add entries (as opposed to using 'echo').
So, with this commit the internals of field management
has been completely reimagined. It is now based on the
integer type, not a character. And whereas that former
design used the high order bit to show the 'on' state,
thus yielding an unprintable character, the new design
uses the low order bit for the state. As such, numbers
will be kept small and an even number will be an 'off'
field whereas an odd number will become an 'on' state.
The bottom line is that this new design will afford an
unlimited number of new fields while keeping an rcfile
completely free of that potential unprintable garbage.
And it is embarrassingly easy to extend the maximum of
supportable fields from the currently implemented 100.
Who knows, maybe a future patch will prove this point.
[ unless a subsequent commit proves otherwise, given ]
[ the dramatic differences in rcfile contents, i had ]
[ to abandon the practice of supporting old rcfiles. ]

top: honor the restrictive, crufty old top rcfile
At one time, new top silently defaulted when an rcfile
was found to be incompatible. This is exactly what
the old top did. However, after some discussion it
was decided top should alert the user and thereby
save the system administrator some headaches.
Now, some are upset over the fatal error, proving you
can't please everybody. But in all fairness, given
the difficulty of customizing old top, any reluctance
to delete an old saved rcfile is understandable.
To ease transition to this new top, old style rcfiles
will now be honored and converted to the new format.
And if not disabled at ./configure time via CFLAGS,
a user will be warned when an old style rcfile is
about to be overwritten using the 'W' command.
Lastly, the config validation logic was enhanced to
help ensure both types of rcfile haven't been edited
manually and possibly made unuseable.

top: provide the means to adjust scaled process memory
This commit is an unrequested outgrowth of the earlier
change dealing with summary area memory field scaling.
That user selectable scaling provision is now extended
to include 6 (at present) task oriented memory fields.
The new companion 'e' (lower case) interactive command
has been added and, like the 'E' command, it can cycle
each of the currently displayed memory columns between
KiB through TiB. There are, however, some differences.
Where '+' indicates summary area truncation at a given
radix, task memory fields are automatically scaled for
their column. Thus, not all rows use the same scaling.
And, while summary area field widths were not changed,
the task memory columns were widened in order to offer
more meaningful data when the radix was increased. The
precision is automatically increased in step with each
radix: MiB displays 2 decimal places, GiB 3 and TiB 4.
To compliment that additional precision, both the %CPU
and %MEM fields were widened by 1 column and now offer
precision up to 3 decimal places. But, unique to %CPU,
widening could already have occurred due to the number
of processors in some massively parallel boxes. At any
rate, total extra width for both memory and percentage
fields could amount to twenty (precious) columns more.
So for both the memory and % fields the original width
(along with loss of precision) can be restored via new
compiler conditionals which this commit also provides.
p.s. and it will be rcfile preserved for any restarts!
(now that we know a '.' + 2 spaces is squeezed to one)
(everything's perfectly justified, but it's just luck)

top: highlight all regular search string(s) when found
With the recent inspect search highlight provisions in
place, the lack of highlighting in task based searches
has grown from being only irritating to a real defect.
Thus, this commit introduces parallel functionality to
those searches initiated within a visible task window.
And just as separate inspect searches are possible for
each selection, per window task searches are provided.
However, it should be noted that there are differences
between task based searches and inspect type searches:
* There is no concept of out-of-view data when dealing
. with task rows -- if the data can't bee seen, it has
. not, in fact, been constructed from a proc_t struct.
* While inspect data is output at the character level,
. up to now all task display data was only potentially
. output and it was always based on a complete string.
* With task search highlighting, rows now containing a
. match must be output in pieces and, therefore, can't
. be optimized away like other rows which haven't been
. been altered. This is because top cannot predict the
. the contents of a search string or, how many matches
. might occur in a given row. Short search strings and
. many matches would raise buffer needs geometrically.

uses the low order bit for the state. As such, numbers
will be kept small and an even number will be an 'off'
field whereas an odd number will become an 'on' state.
The bottom line is that this new design will afford an
unlimited number of new fields while keeping an rcfile
completely free of that potential unprintable garbage.
And it is embarrassingly easy to extend the maximum of
supportable fields from the currently implemented 100.
Who knows, maybe a future patch will prove this point.

top: provide an unlimited capacity for field additions
With each of those references shown below, the maximum
number of fields was increased. However, with a 'char'
based implementation we're nearing the upper limits of
total displayable fields. We currently use 76 of a max
of 86 fields. With extra effort, 94 might be possible.
But 94 is the absolute upper limit of possible fields!
Moreover, the current implementation yields characters
that were unprintable in the rcfile. This could become
an issue with that 'inspect' feature when/if an rcfile
is edited to add entries (as opposed to using 'echo').
So, with this commit the internals of field management
has been completely reimagined. It is now based on the

thus yielding an unprintable character, the new design

top: highlight all regular search string(s) when found
With the recent inspect search highlight provisions in
place, the lack of highlighting in task based searches
has grown from being only irritating to a real defect.
Thus, this commit introduces parallel functionality to
those searches initiated within a visible task window.
And just as separate inspect searches are possible for
each selection, per window task searches are provided.
However, it should be noted that there are differences
between task based searches and inspect type searches:
* There is no concept of out-of-view data when dealing
. with task rows -- if the data can't bee seen, it has
. not, in fact, been constructed from a proc_t struct.
* While inspect data is output at the character level,
. up to now all task display data was only potentially
. output and it was always based on a complete string.
* With task search highlighting, rows now containing a
. match must be output in pieces and, therefore, can't
. be optimized away like other rows which haven't been
. been altered. This is because top cannot predict the
. the contents of a search string or, how many matches
. might occur in a given row. Short search strings and
. many matches would raise buffer needs geometrically.
(now that we know a '.' + 2 spaces is squeezed to one)
(everything's perfectly justified, but it's just luck)

top: allow more flexible approach for startup defaults
Those references below offer more detail regarding the
default startup changes beginning with version 3.3.10.
It is important to remember that all such changes were
supposed to impact only new users or users who had not
saved the personal config file (via that 'W' command).
However, I introduced a bug wherein the rcfile was not
fully honored. This gave the changes a bad reputation.
That bug was corrected in release 3.3.11 but the issue
of default startup options keeps resurfacing. And it's
clear there's no consensus on what should be included.
Our --disable-modern-top configure option is of little
help since it remains an all-or-nothing approach. What
we need is an answer offering unlimited customization.
So, this commit will provide distribution packagers or
system administrators with a much more flexible way to
set their own preferred startup default configuration.
A new rcfile is being introduced: '/etc/topdefaultrc',
whose format/content is the same as a personal rcfile.
Thus once a 'proper' enterprise configuration has been
established and saved via 'W', it can be copied to the
/etc/ directory. Thereafter, startup in the absence of
a saved rcfile will use that configuration as default.
Now if a distribution packager or system administrator
wishes to expose their users to some of top's advanced
capabilities they can do so gradually. Perhaps setting
up graph mode for summary area task and memory display
while retaining the %CPU sort could be tried. Or maybe
showing colors, but better customized for a particular
terminal emulator. Such possibilities are now endless.
[ in exploiting this new capability, i hope that the ]
[ other windows (alt display mode) aren't overlooked ]

top: provide an unlimited capacity for field additions
With each of those references shown below, the maximum
number of fields was increased. However, with a 'char'
based implementation we're nearing the upper limits of
total displayable fields. We currently use 76 of a max
of 86 fields. With extra effort, 94 might be possible.
But 94 is the absolute upper limit of possible fields!
Moreover, the current implementation yields characters
that were unprintable in the rcfile. This could become
an issue with that 'inspect' feature when/if an rcfile
is edited to add entries (as opposed to using 'echo').
So, with this commit the internals of field management
has been completely reimagined. It is now based on the
integer type, not a character. And whereas that former
design used the high order bit to show the 'on' state,
thus yielding an unprintable character, the new design
uses the low order bit for the state. As such, numbers

top: provide an unlimited capacity for field additions
With each of those references shown below, the maximum
number of fields was increased. However, with a 'char'
based implementation we're nearing the upper limits of
total displayable fields. We currently use 76 of a max
of 86 fields. With extra effort, 94 might be possible.
But 94 is the absolute upper limit of possible fields!
Moreover, the current implementation yields characters
that were unprintable in the rcfile. This could become
an issue with that 'inspect' feature when/if an rcfile
is edited to add entries (as opposed to using 'echo').
So, with this commit the internals of field management
has been completely reimagined. It is now based on the
integer type, not a character. And whereas that former
design used the high order bit to show the 'on' state,
thus yielding an unprintable character, the new design
uses the low order bit for the state. As such, numbers
will be kept small and an even number will be an 'off'
field whereas an odd number will become an 'on' state.
The bottom line is that this new design will afford an
unlimited number of new fields while keeping an rcfile
completely free of that potential unprintable garbage.
And it is embarrassingly easy to extend the maximum of
supportable fields from the currently implemented 100.
Who knows, maybe a future patch will prove this point.

top: honor the restrictive, crufty old top rcfile
At one time, new top silently defaulted when an rcfile
was found to be incompatible. This is exactly what
the old top did. However, after some discussion it
was decided top should alert the user and thereby
save the system administrator some headaches.
Now, some are upset over the fatal error, proving you
can't please everybody. But in all fairness, given
the difficulty of customizing old top, any reluctance
to delete an old saved rcfile is understandable.
To ease transition to this new top, old style rcfiles
will now be honored and converted to the new format.
And if not disabled at ./configure time via CFLAGS,
a user will be warned when an old style rcfile is
about to be overwritten using the 'W' command.
Lastly, the config validation logic was enhanced to
help ensure both types of rcfile haven't been edited
manually and possibly made unuseable.

top: refactor 'scale_tics' function for better scaling
This patch refactors the 'scale_tics' function to more
closely parallel uptime shown on the first line of the
summary area. The old logic has been preserved through
the header file's new #define SCALE_FORMER provision.
However, the former logic was actually a big disaster.
These are some potential problems with that old logic:
1. With respect to our time fields top no longer deals
solely with cpu time. So, the old limits of '68 weeks'
could possibly be insufficient to reflect those times.
2. Given the widths of top's new time fields, the code
never got beyond scaling to hours. For example, with a
ridiculously large span of 19 years, the scaled result
would then be shown as '167832h'. We never reached the
days ('6993d') or even the weeks ('999w') equivalents.
3. Similarly, with that 'TIME+' field and a large tics
value, results would then appear as 'MMMMMM:SS' rather
than the more meaningful 'HH:MM:SS' or days and hours.
So henceforth we will adopt these scaling conventions:
MMM:SS.hh ... minutes:seconds.hundredths
MMM:SS ...... minutes:seconds
HH,MM ....... hours,minutes
D+H ......... days+hours (with 'd' & 'h' suffixes)
D ........... days (with 'd' suffix)
W+D ......... weeks+days (with 'w' & 'd' suffixes)
W ........... weeks (with 'w' suffix)
Note that, unlike our former scaling logic, that 'MMM'
portion won't be allowed to grow unconditionally. It's
limited (arbitrarily?) to 360 total minutes (6 hours).
Additionally, the 'HH' guy will be limited to 96 hours
(4 days) while that 'D' limit was set at 14 (2 weeks).
Whenever a limit is hit, scaling will advance a level.

top: provide an unlimited capacity for field additions
With each of those references shown below, the maximum
number of fields was increased. However, with a 'char'
based implementation we're nearing the upper limits of
total displayable fields. We currently use 76 of a max
of 86 fields. With extra effort, 94 might be possible.
But 94 is the absolute upper limit of possible fields!
Moreover, the current implementation yields characters
that were unprintable in the rcfile. This could become
an issue with that 'inspect' feature when/if an rcfile
is edited to add entries (as opposed to using 'echo').
So, with this commit the internals of field management
has been completely reimagined. It is now based on the
integer type, not a character. And whereas that former
design used the high order bit to show the 'on' state,
thus yielding an unprintable character, the new design
uses the low order bit for the state. As such, numbers
will be kept small and an even number will be an 'off'
field whereas an odd number will become an 'on' state.
The bottom line is that this new design will afford an
unlimited number of new fields while keeping an rcfile
completely free of that potential unprintable garbage.
And it is embarrassingly easy to extend the maximum of
supportable fields from the currently implemented 100.
Who knows, maybe a future patch will prove this point.
[ unless a subsequent commit proves otherwise, given ]
[ the dramatic differences in rcfile contents, i had ]
[ to abandon the practice of supporting old rcfiles. ]

top: refactored for correct multi-byte string handling
When this project first began implementing translation
support nearly 6 years ago, we overcame many 'gettext'
obstacles and limitations. And, of course, there were
not any actual translations at the time so our testing
was quite limited plus, in many cases, only simulated.
None of that, however, can justify or excuse the total
lack of attention to top's approach to NLS, especially
since some actual translations have existed for years.
When the issue referenced below was raised, I suffered
immediate feelings of anxiety, doubt and pending doom.
This was mostly because top strives to avoid line wrap
at all costs and that did not bode well for multi-byte
translated strings, using several bytes per character.
I was also concerned over possible performance impact,
assuming it was even possible to properly handle utf8.
But, after wrestling with the problem for several days
those initial feelings have now been replaced by guilt
over any trouble I initially caused those translators.
One can only imagine how frustrating it must have been
after the translation effort to then see top display a
misaligned column header and fields management page or
truncated screens like those of help or color mapping.
------------------------------------------------------
Ok, with that off my chest let's review these changes,
now that top properly handles UTF8 multi-byte strings.
. Performance - virtually all of this newly added cost
for multi-byte support is incurred during interactions
with the user. So, performance is not really an issue.
The one occasion when performance is impacted is found
during 'summary_show()' processing, due to an addition
of one new call to 'utf8_delta()' in 'show_special()'.
. Extra Wide Characters - I have not yet and may never
figure out a way to support languages like zh_CN where
the characters can be wider than most other languages.
. Translated User Name - at some future point we could
implement translation of user names. But as the author
of the issue acknowledged such names are non-standard.
Thus task display still incurs no new multi-byte costs
beyond those already incurred in that escape.c module.
For raising the issue I extend my sincerest thanks to:

top: extend multi-byte support to 'Inspection' feature
The previous commit implemented multi-byte support for
the basic top user interaction and display provisions.
This commit completes multi-byte support by addressing
that 'Inspect Other Output' feature (the 'Y' command).
Few people probably exploit this very powerful feature
which allows the perusing of any file or piped output.
And even if nobody uses 'Y', someone will stumble over
it on the help screen and try it out. Assuming top was
not built with INSP_OFFDEMO defined, they'll end up on
the screen our translators have faithfully translated.
Without this patch, such a screen would display with a
bunch of 'unprintable' characters which will then show
in the standard (less-like) way as: '^A', '<C3>', etc.
In other words, those poor screens will be a big mess!
[ this program can even display an executable binary ]
[ while at that same time supporting Find/Find Next. ]
[ imagine, a file with no guarantee of real strings! ]
[ just try a Find using less with such binary files. ]
With this commit, the translated 'Y' demo screens will
now be properly shown, providing no invalid multi-byte
characters have been detected. Should that be the case
then they'll be displayed in that less-like way above.
And, if users go on to fully exploit this 'Y' command,
there is a good chance that a file or pipe might yield
output in a utf-8 multi-byte form. Should that be true
such output will thus be handled appropriately by top.
[ in many respects, this change was more challenging ]
[ than the basic support within the previous commit. ]
[ story of my life: least used = most effort needed. ]
Many thanks to our procps-ng translators which enabled
a proper test of these changed 'Y' command provisions:
. Vietnamese: Trần Ngọc Quân
. Polish: Jakub Bogusz
. German: Mario Blättermann
. French: Frédéric Marchal, Stéphane Aulery
[ and my sincerest apologies too, for my negligence! ]

top: add a flexible 'Inspect' capability
This commit introduces an extremely powerful, flexible
brand new capability. Now, users can pause the normal
iterative display and inspect the contents of any file
or output from any script, command, or even pipelines.
It's invoked via the 'Y' interactive command which, in
turn, is supported with simple user supplied additions
as new entries in the top personal configuration file.
A separate new 'Inspect' window supports scrolling and
searching, similar to the main top display. Except it
extends existing 'L'/'&' (locate/locate-next) commands
so that an out-of-view match automatically adjusts the
horizontal position bringing such data into view. And
it provides for multiple successive same line matches.
Also, the basic 'more/less' navigation keys are active
in this new 'Inspect' window, to ease user transition.
There are no program changes required when entries are
added to or deleted from the rcfile. And there are no
known limits to the complexity of a script, command or
pipeline, other than the unidirectional nature imposed
by the 'popen' function call which top cannot violate.
Since it's impossible to predict exactly what contents
will be generated, top treats all output as raw binary
data. Any control characters display in '^C' notation
while all other unprintable characters show as '<AB>'.
The biggest problem encountered was with the find/next
capability since that strstr guy was really diminished
given the possibility that numerous 'strings' could be
encountered *within* many of top's raw, binary 'rows'.
Oh, and another problem was in maintaining the perfect
left & right text justification of this commit message
along with all of the commit summaries. Some of those
summaries (like this very one) are of course, slightly
shorter, to make room for the 'man document' addition.
Enjoy!

(4 days) while that 'D' limit was set at 14 (2 weeks).
Whenever a limit is hit, scaling will advance a level.

top: add a flexible 'Inspect' capability
This commit introduces an extremely powerful, flexible
brand new capability. Now, users can pause the normal
iterative display and inspect the contents of any file
or output from any script, command, or even pipelines.
It's invoked via the 'Y' interactive command which, in
turn, is supported with simple user supplied additions
as new entries in the top personal configuration file.
A separate new 'Inspect' window supports scrolling and
searching, similar to the main top display. Except it
extends existing 'L'/'&' (locate/locate-next) commands
so that an out-of-view match automatically adjusts the
horizontal position bringing such data into view. And
it provides for multiple successive same line matches.
Also, the basic 'more/less' navigation keys are active
in this new 'Inspect' window, to ease user transition.
There are no program changes required when entries are
added to or deleted from the rcfile. And there are no
known limits to the complexity of a script, command or
pipeline, other than the unidirectional nature imposed
by the 'popen' function call which top cannot violate.
Since it's impossible to predict exactly what contents
will be generated, top treats all output as raw binary
data. Any control characters display in '^C' notation
while all other unprintable characters show as '<AB>'.
The biggest problem encountered was with the find/next
capability since that strstr guy was really diminished
given the possibility that numerous 'strings' could be
encountered *within* many of top's raw, binary 'rows'.
Oh, and another problem was in maintaining the perfect
left & right text justification of this commit message
along with all of the commit summaries. Some of those
summaries (like this very one) are of course, slightly
shorter, to make room for the 'man document' addition.
Enjoy!

top: extend multi-byte support to 'Inspection' feature
The previous commit implemented multi-byte support for
the basic top user interaction and display provisions.
This commit completes multi-byte support by addressing
that 'Inspect Other Output' feature (the 'Y' command).
Few people probably exploit this very powerful feature
which allows the perusing of any file or piped output.
And even if nobody uses 'Y', someone will stumble over
it on the help screen and try it out. Assuming top was
not built with INSP_OFFDEMO defined, they'll end up on
the screen our translators have faithfully translated.
Without this patch, such a screen would display with a
bunch of 'unprintable' characters which will then show
in the standard (less-like) way as: '^A', '<C3>', etc.
In other words, those poor screens will be a big mess!
[ this program can even display an executable binary ]
[ while at that same time supporting Find/Find Next. ]
[ imagine, a file with no guarantee of real strings! ]
[ just try a Find using less with such binary files. ]
With this commit, the translated 'Y' demo screens will
now be properly shown, providing no invalid multi-byte
characters have been detected. Should that be the case
then they'll be displayed in that less-like way above.
And, if users go on to fully exploit this 'Y' command,
there is a good chance that a file or pipe might yield
output in a utf-8 multi-byte form. Should that be true
such output will thus be handled appropriately by top.
[ in many respects, this change was more challenging ]
[ than the basic support within the previous commit. ]
[ story of my life: least used = most effort needed. ]
Many thanks to our procps-ng translators which enabled
a proper test of these changed 'Y' command provisions:
. Vietnamese: Trần Ngọc Quân
. Polish: Jakub Bogusz
. German: Mario Blättermann
. French: Frédéric Marchal, Stéphane Aulery
[ and my sincerest apologies too, for my negligence! ]

top: highlight all regular search string(s) when found
With the recent inspect search highlight provisions in
place, the lack of highlighting in task based searches
has grown from being only irritating to a real defect.
Thus, this commit introduces parallel functionality to
those searches initiated within a visible task window.
And just as separate inspect searches are possible for
each selection, per window task searches are provided.
However, it should be noted that there are differences
between task based searches and inspect type searches:
* There is no concept of out-of-view data when dealing
. with task rows -- if the data can't bee seen, it has
. not, in fact, been constructed from a proc_t struct.
* While inspect data is output at the character level,
. up to now all task display data was only potentially
. output and it was always based on a complete string.
* With task search highlighting, rows now containing a
. match must be output in pieces and, therefore, can't
. be optimized away like other rows which haven't been
. been altered. This is because top cannot predict the
. the contents of a search string or, how many matches
. might occur in a given row. Short search strings and
. many matches would raise buffer needs geometrically.
(now that we know a '.' + 2 spaces is squeezed to one)
(everything's perfectly justified, but it's just luck)
