I use Vim to edit python code and can execute any selection (F3) or single
lines (F2)
whenever I want to (Vim must be built to include the python interpreter).
Here is the according Vimrc code
"pyout if present must be right below
"r replaces, p prints, symb sets the start
py << EOL
def PrintCurrentLine(*args):
cur_str = vim.current.line
action, symb = None, None
for i in args:
if i in ["r","p"]: action = i
else: symb = i
try: start = cur_str.rindex(symb)+len(symb)
except: start = 0
eval(compile("pyoutres="+cur_str[start:],'<string>','exec'),globals())
result = eval("pyoutres",globals())
if action == "r":
vim.current.line = cur_str[:start]+str(result)
else:
iPy=PyOutput()
if iPy != -1:
resS=cur_str+"=================="+'\n'+str(result)+'\n'
resL=resS.split('\n')
vim.buffers[iPy].range(0,0).append(resL)
vim.command("wincmd b")
vim.command("normal gg")
vim.command("wincmd p")
else:
print result
EOL
command -narg=* Pyl python PrintCurrentLine(<f-args>)
map <F2> :py PrintCurrentLine()<CR>
python << EOL
def EvaluateCurrentRange():
c_r=vim.current.range
i=0
while c_r[0].startswith(' '*(i+1)):
i+=1
rngstr='\n'.join([ln[i:] for ln in c_r])
eval(compile(rngstr,'<string>','exec'),globals())
EOL
map <F3> :py EvaluateCurrentRange()<CR>
