I'm trying to avoid the inevitable conflict with -w/--word, which will
probably become important when exploring non-32-bit filesystem
configurations.
Renaming this to -t/--wait still conflicts with -t/--tree and -t/--tiny,
but as a debug-only flag, I think these are less important.
Oh, and -t/--trace, but test.py/bench.py are already quite different in
their flag naming (see -d/--disk vs -d/--diff).
---
Renamed a few other flags while tweaking things:
- -t/--tiny -> --tiny (dropped shortform)
- -w/--word-bits -> -w/--word/--word-bits
- -t/--tree -> -R/--tree/--rbyd/--tree-rbyd
- -R/--tree-rbyd -> -Y/--rbyd-all/--tree-rbyd-all
- -B/--tree-btree -> -B/--btree/--tree-btree
After tinkering with it a bit, I think the -R/-Y/-B set of flags are a
decent way to organize the tree renderers. At least --tree-rbyd-all does
a better job of describing the difference between --tree-rbyd and
--tree-rbyd-all.
This adds %i and %I as punescape modifiers for limited printing of
integers with SI prefixes:
- %(field)i - base-10 SI prefixes
- 100 => 100
- 10000 => 10K
- 0.01 => 10m
- %(field)I - base-2SI prefixes
- 128 => 128
- 10240 => 10Ki
- 0.125 => 128mi
These can also easily include units as a part of the punescape string:
- %(field)iops/s => 10Kops/s
- %(field)IB => 10KiB
This is particularly useful in plotmpl.py for adding explicit
x/yticklabels without sacrificing the automatic SI-prefixes.
This actually binds our custom write/writeln functions as methods to the
file object:
def writeln(self, s=''):
self.write(s)
self.write('\n')
f.writeln = writeln.__get__(f)
This doesn't really gain us anything, but is a bit more correct and may
be safer if other code messes with the file's internals.
Not sure what the point of this was, I think it was copied from a d3
example svg at some point. But it forces the svg to always fit in the
window, even if this makes the svg unreadable.
These svgs tend to end up questionably large in order to fit in the most
info, so the unreadableness ends up a real problem for even modest
window sizes.
- codemapd3.py -> codemapsvg.py
- dbgbmapd3.py -> dbgbmapsvg.py
- treemapd3.py -> treemapsvg.py
Originally these were named this way to match plotmpl.py, but these
names were misleading. These scripts don't actually use the d3 library,
they're just piles of Python, SVG, and Javascript, modelled after the
excellent d3 treemap examples.
Keeping the *d3.py names around also felt a bit unfair to brendangregg's
flamegraph SVGs, which were the inspiration for the interactive
component. With d3 you would normally expect a rich HTML page, which is
how you even include the d3 library.
plotmpl.py is also an outlier in that it supports both .svg and .png
output. So having a different naming convention in this case makes
sense to me.
So, renaming *d3.py -> *svg.py. The inspiration from d3 is still
mentioned in the top-level comments in the relevant files.
