ips

listdir, basename, dirname, newfolder, finfo

e.g.,

fpath = "....../"
ips.listdir(fpath, kind='pdf', sort_by="size", ascending=0, output = 'df')

it filters the ‘.pdf’ files, and sort by the (file-size/name, length of name, create_time, mod_time, last_open_time …) it returns a DataFrame or BoxList (setting by ‘output’)

dir_data, dir_fig = newfolder(fpath, {'data', 'fig'}) # create folder

finfo(fpath) # get info: size, creation time, mod time, parent_path, fname, kind...

dir_lib(lib_of_interest) # get the fpath

list_func/func_list (same)

list functions in a package

fload, fsave, figsave

e.g.,

fload(fpath, kind=None, **kwargs)

load file (docx, pdf, image, md, json,csv,txt, html, yaml, xml, xlsx…) or save file.

# figsave, as used in matlab. 
figsave(dir_save, "fname.pdf", dpi=300)

pdf2img, img2pdf, docx2pdf

extract images from a PDF, or merge images into a pdf file

pdf2img(dir_pdf, dir_save=None, page=None, kind="png",verbose=True, **kws)
pdf2img(fpath, page=[None, None])  # means extract all pages
# processing page: 1
# processing page: 2
# processing page: 3
# processing page: 4
# processing page: 5

img2pdf(dir_img, kind="jpeg",page=None, dir_save=None, page_size="a4", dpi=300)

docx2pdf(dir_docx, dir_save) # convert docx to pdf

paper_size

quickly get the size info

paper_size('a4') # [210, 297]
paper_size('card') # [85.6, 53.98]

str2num, num2str, str2list

str2num(“123.345 dollers”,2)# => 123.35 (float) 

str2list("abcd") # ['a','b','c','d']
