This library provides a text mode progressbar. This is tipically used to display the progress of a long running operation, providing a visual clue that processing is underway. The ProgressBar class manages the progress, and the format of the line is given by a number of widgets. A widget is an object that may display diferently depending on the state of the progress. There are three types of widget: - a string, which always shows itself; - a ProgressBarWidget, which may return a diferent value every time it's update method is called; and - a ProgressBarWidgetHFill, which is like ProgressBarWidget, except it expands to fill the remaining width of the line. The progressbar module is very easy to use, yet very powerful. And automatically supports features like auto-resizing when available. sNilton Volpatos$first-name dot last-name @ gmail.coms 2006-05-07s2.2iÿÿÿÿN(tarray(tioctltProgressBarWidgetcBseZdZd„ZRS(sThis is an element of ProgressBar formatting.

The term_width parameter may be an integer. Or None, in which case it will try to guess it, if it fails it will default to 80 columns. The simple use is like this: >>> pbar = ProgressBar().start() >>> for i in xrange(100): ... # do something ... pbar.update(i+1) ... >>> pbar.finish() But anything you want to do is possible (well, almost anything). You can supply different widgets of any type in any order. And you can even write your own widgets! There are many widgets already shipped and you should experiment with them. When implementing a widget update method you may access any attribute or function of the ProgressBar object calling the widget's update method. The most important attributes you would like to access are: - currval: current value of the progress, 0 <= currval <= maxval - maxval: maximum (and final) value of the progress - finished: True if the bar is have finished (reached 100%), False o/w - start_time: first time update() method of ProgressBar was called - seconds_elapsed: seconds elapsed since start_time - percentage(): percentage of the progress (this is a method) idcCsÉ|djpt‚||_||_||_t|_|djoJy3|iddƒtiti |iƒt |_Wq˜d|_ q˜Xn ||_ d|_ t|_ d|_d|_d|_dS(NiiOiÿÿÿÿ(tAssertionErrorRtwidgetstfdtFalset signal_settNonet handle_resizetsignaltSIGWINCHtTruet term_widthRRtprev_percentaget start_timeR(RRRARJRB((sJC:\Documents and Settings\red08xgu\Desktop\python_webupdate\progressbar.pyR Ós$           cCs8tdt|itidƒƒd \}}||_dS(Nthtiit(RRRBttermiost TIOCGWINSZRJ(RtsignumtframeRMtw((sJC:\Documents and Settings\red08xgu\Desktop\python_webupdate\progressbar.pyRFês+cCs|id|iS(s'Returns the percentage of the progress.gY@(RR(R((sJC:\Documents and Settings\red08xgu\Desktop\python_webupdate\progressbar.pyR*îsc Cs g}g}d}d}x¸t|iƒD]§\}}t|tƒo(|i|ƒ|i|ƒ|d7}q(t|ttfƒo!|i|ƒ|t|ƒ7}q(|i|ƒ}|t|ƒ7}|i|ƒq(Wx3|D]+}||i||i ||ƒ||>> pbar = ProgressBar().start() >>> for i in xrange(100): ... # do something ... pbar.update(i+1) ... >>> pbar.finish() i(R(R((sJC:\Documents and Settings\red08xgu\Desktop\python_webupdate\progressbar.pytstarts cCs8|i|iƒ|iotititiƒndS(s&Used to tell the progress is finished.N(RRRDRGRHtSIG_DFL(R((sJC:\Documents and Settings\red08xgu\Desktop\python_webupdate\progressbar.pytfinish+s N(RRRtdefault_widgetsREtsyststderrR RFR*R^RaRbRReRg(((sJC:\Documents and Settings\red08xgu\Desktop\python_webupdate\progressbar.pyR?µs        t__main__cCs‰dtƒdtdtƒƒdtƒdtƒg}td|ddƒiƒ}x)tdƒD]}|id|d ƒq[W|i ƒHdS( NsTest: R>R.RARi€–˜i@Bi i( R)R+R%R RR?RetrangeRRg(RARR[((sJC:\Documents and Settings\red08xgu\Desktop\python_webupdate\progressbar.pytexample19s  cCs—dtfd„ƒY}|ƒdtƒdtƒdtƒg}td|ddƒ}|iƒx)td ƒD]}|id |d ƒqiW|iƒHdS( NtCrazyFileTransferSpeedcBseZdZd„ZRS(s%It's bigger between 45 and 80 percentcSsMd|iƒjo djnodti||ƒSti||ƒSdS(Ni-iPs Bigger Now (R*RR(RR((sJC:\Documents and Settings\red08xgu\Desktop\python_webupdate\progressbar.pyRFs$(RRRR(((sJC:\Documents and Settings\red08xgu\Desktop\python_webupdate\progressbar.pyRnDss <<>> R>RARi€–˜i€„ii( RR+R)R R?ReRlRRg(RnRARR[((sJC:\Documents and Settings\red08xgu\Desktop\python_webupdate\progressbar.pytexample2Cs'   cCsztdƒdtƒdtdƒg}td|ddƒiƒ}x)tdƒD]}|id|d ƒqLW|iƒHdS( Nt>R>tR.t0R/t[R0t]RARiôidii2gš™™™™™É?iõ( R)R+R RR?ReRlR tsleepRRg(RARR[((sJC:\Documents and Settings\red08xgu\Desktop\python_webupdate\progressbar.pytexample4_s    (Rt __author__t__author_email__t__date__t __version__RiR RtfcntlRRPt ImportErrorRGtobjectRR R RR%R)R+R<RhR?RtosRmRoRrRw(((sJC:\Documents and Settings\red08xgu\Desktop\python_webupdate\progressbar.pyt(s@
