If you wish to reproject to WGS84, you can supply the EPSG code Whitelist and blacklist or filter certain properties. You can also reduce the number of decimals for coordinates and properties, Minify (compress) each input GeoJSON or ESRI shapefile by replacing theĪttribute keys with a shorter representation (typically, its first letter). That's why it normally uses a streaming mode, so also large files can be processed easily (after which you can try reprojecting it again). In case your GeoJSON file is too large for node.js to handle, this may fail. The tool works in two modes: for files that require reprojection or topojson output, it will read in all data at once. only keep those features whose properties satisfy certain conditions.
Warning: If you already have property keys like a or b, it may map them to the wrong name. Minify the length of the keys by mapping each key name to a single or double letter combination: option -k converts long property keys such as my_long_property_name to a or ab.Reducing the number of decimals used for coordinates: option -c 5 to keep 5 decimals.
(In this case, memory object.A small tool to minify (compress) a GeoJSON file by: with open(os.path.join(dirname, filename), "r") as assetfile: I learned the hard way that you have to be sure to os.path.join() the filenames and the directories.
The changes in my if statements in the above code open the asset files as strings, then pass them along for minification. JsMinified.write(rjsmin.jsmin(assetdata, keep_bang_comments=True)) With open(os.path.join(dirname, filename), "r") as assetfile:Īssetdata = assetfile.read().replace("\n", "")ĬssMinified.write(rcssmin.cssmin(assetdata, keep_bang_comments=True)) You have to open and read the CSS and JS files by yourself. ThemePak.writestr(os.path.join(dirname, filename), jsMinified.getvalue())Īs stated by and rjsmin.jsmin() expect the first element to be the CSS respectively JS code to minify as string. JsMinified.write(rjsmin.jsmin(filename, keep_bang_comments=True)) ThemePak.writestr(os.path.join(dirname, filename), cssMinified.getvalue()) ThemePak.write(os.path.join(dirname, filename))ĬssMinified.write(rcssmin.cssmin(filename, keep_bang_comments=True)) If not filename.endswith((".css", ".js")): ThemePak = zipfile.ZipFile(pakName +".tpk", "w")įor dirname, subdirs, files in os.walk("theme_files"): PakName = input("Theme Name: ").replace(" ", "_").lower() However, the minified css and javascript files have no content inside of them other than their own file name.Įxample: the content of the file (supposedly minified) theme.css would be "theme.css" It would output the whole directory structure into the generated. If I used the code below (bottom of the post), and the directory structure inside of theme_files was such: \ I am trying to make a python script that will package the contents of a directory and minify all of the JavaScript and CSS scripts.
