linux - Remove redundant braces from code -

-

i trying use tr command or similar command perform specific text manipulation block:

if (/*condition*/) {     statement1; } int a=3; if (a) {     statement1;     statement2; } else {     statement1;     statement2;     statement3;     statement4;     ///may more lines }

i want remove single line commands , this:

if (/*condition*/)     statement1; int a=3; if (a) {     statement1;     statement2; } else {     statement1;     statement2;     statement3;     statement4;     ///may more lines }

i've tried tr -s '{}' ' ' <file.txt squeezes of braces, not specific single line format.

thanks

you can set record separator either { or } , check how many fields have. if there more one, print brackets around:

$ awk -v rs=[{}] 'nf>1{$0="{"$0"}"}1' file if(true)   statement;   if(false)  { statement1; statement2; }

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...
