海外TECH	DEV Community	Microsoft Reinforcement Learning Open Source Fest 2022 – Native CSV Parser	https://dev.to/hollowman6/microsoft-reinforcement-learning-open-source-fest-2022-native-csv-parser-fl	Microsoft Reinforcement Learning Open Source Fest Native CSV ParserPR Tutorial IntroductionMy project here at the Reinforcement Learning Open Source Fest is to add the native CSV parsing feature for the Vowpal Wabbit So why do I choose to implement native CSV parsing CSV is one of the most popular file formats used in the machine learning dataset and is often delivered as the default format in competitions such as Kaggle CSV files have the same schema for each example while VW text format doesn t Although converters in Python and Perl have been written which convert these files to VW text format it would be convenient if VW could understand CSV files natively I also want to challenge myself as there is a surprising amount of complexity in the design of implementing a generalized parser for CSV so this project is as much about considering all of the design pieces as implementing a working parser My choice and time devoted also pay off since my project has already got merged into the VW upstream About CSVCSV files are often separated by commas or tabs however alternative delimiter separated files are often given a csv extension despite the use of a non comma field separator This loose terminology can cause problems in data exchange Many applications that accept CSV files have options to select the delimiter character and the quotation character Semicolons are often used instead of commas in many European locales in order to use the comma as the decimal separator and possibly the period as a decimal grouping character Separating fields with the field separator is CSV s foundation but commas in the data have to be handled specially How do we handle CSV files The short answer is that we follow the RFC and MIME standards The technical standard RFC formalizes the CSV file format and defines the MIME type text csv for the handling of text based fields However the interpretation of the text of each field is still application specific Files that follow the RFC standard can simplify CSV exchange and should be widely portable Here are its requirements Lines will end with CR or CRLF characters and it is optional for the last line CSV files can have an optional header record There is no sure way to detect whether it is present so care is required when importing Each record should contain the same number of separated fields Any field may be quoted with double quotes Fields containing a double quote or commas should be quoted If double quotes are used to enclose fields then a double quote in a field must be represented by two double quote characters Dig into detailsAllows specifying the CSV field separator by csv separator default is but or are reserved and not allowed to use since the double quote is for escape vertical bar for separating the namespace and feature names can be used in labels For each separated field auto remove the outer double quotes of a cell when it pairs csv separator symbols that appeared inside the double quoted cells are not considered as a separator but a normal string character Double quotes that appear at the start and end of the cell will be considered to enclose fields Other quotes that appear elsewhere and out of the enclose fields will have no special meaning This is also how Microsoft Excel parses If double quotes are used to enclose fields then a double quote appearing inside a field must be escaped by preceding it with another double quote and will remove that escape symbol during parsing Use header line for feature names and possibly namespaces specify label and tag using label and tag by default For each separated field in header except for tag and label it may contain namespace and feature name separated by namespace separator vertical bar csv header to override the CSV header by providing the header Combined with csv no file header we assume that there is no header in the CSV file and under such condition specifying csv header for the header is a must If the number of the separated fields for current parsing line is greater than the header an error will be thrown Trim the field for ASCII white space r n f v as well as some UTF BOM characters xef xbb xbf before separation If no namespace is separated will use empty namespace Separator supports using t to represent tabs Otherwise if assigning more than one character an error will be thrown Directly read the label as string interpret it using the VW text label parser Will try to judge if the feature values are float or string if NaN will consider it as a string quoted numbers are always considered as strings If the feature value is empty will skip that feature Reset the parser when EOF of a file is met for possible multiple input file support Support using csv ns value to scale the namespace values by specifying the float ratio e g csv ns value a b which the namespace a has a ratio of b of empty namespace of other namespaces of If all the cells in a line are empty then consider it an empty line CSV is not a good fit for the multiline format as evidenced by many empty fields The multiline format often means different lines have different schemas However I still leave the empty line support to ensure that it s flexible and extendable In this case users can still express multiline examples in CSV files although it is not listed as supported We still throw an error if the number of fields separated by the line doesn t match the previous even if all the fields are empty as this usually means typos that users may not intend Some statistics to shareThe project reaches Test and Code Coverage On my computer it takes only ms to handle examples which is comparable to the equivalent VW custom format data file s parsing speed of ms and is equivalent to MB s throughput I have expected that little bit of slower between VW custom text format and the CSV format The VW text parser can parse as it reads since generally the elements have a fixed position while CSV parser needs to store the split elements into an array and look up that array according to the header for labels tags namespace and feature values also there s double quotes trimming and escape support which will definitely cost more time After all I have tried my best to optimize it and the performance is also to my satisfaction You can check using the throughput tool for the unoptimized one during the project And that was actually times improvement VW text Parser bytes parsed in μsMB sUnoptimized

海外TECH	DEV Community	Responsive Font Sizes with Sass Maps and @each	https://dev.to/dostonnabotov/responsive-font-sizes-with-sass-maps-and-each-2ge9	Responsive Font Sizes with Sass Maps and eachHi there Today you will learn how to create responsive font sizes with Sass maps and each method I hope you enjoy it Let s start with a map and we can dive into more complex concepts with each operation First of all create a map that contains font sizes for different screen sizes Call them sm and lg which stand for small and large screen sizes respectively Both should contain the same key with different values If you don t know what Sass map is it is equivalent to object in JavaScript or dictionary in Python type scale scss type scale sm rem rem rem rem rem lg rem rem rem rem rem Okay you might probably know that the best way to create responsive font sizes in CSS is with custom properties And their value can be easily changed It looks something like this example css root fs rem fs rem fs rem fs rem fs rem media only screen and min width em root fs rem fs rem fs rem fs rem fs rem It is easy to change the value of custom properties at any given point However with Sass we have what we call variables whose value are quite tough to change That said we can use the superpower of Sass which will help us to generate those custom properties You might be saying what is the point of making things complicated even though at the end of the day we end up with these custom properties It s true but Sass is like an organized version of CSS and provides features that makes the code more robust and organized Okay let s get back to the topic Our final goal is to turn the map in type scss into custom properties in example css Whenever you see or use Sass maps you might probably have seen each rule It is because they work very well together You can describe them as arrays with map or forEach functions in JavaScript So start by creating a each rule It will take parameters st key in the mapnd value in the maprd the map itselfNote You can name key and value whatever you want but you need to specify which map you are using It looks something like this each example scss colors primary f secondary accent f each key value in colors text key color value Compiled CSS each example css text primary color f text secondary color text accent color f key this weird looking thing is called Interpolation It is used to inject values into strings You can learn more about it here As you can see Sass is a truly powerful language If we describe CSS as JavaScript Sass can be seen as React Ok I hope you got the idea of how each and maps work very well together Now let s generate our responsive font sizes Create a each rule that loops through type map and generate following output example css root fs rem fs rem fs rem fs rem fs rem media only screen and min width em root fs rem fs rem fs rem fs rem fs rem You need to use nested each rule for nested maps Also you might need to use if and else rules You can learn more about them here Yes we have if statements in Sass too Okay start with the first layer of each rule and see what it will output style scss use type scale as root each key value in type scale key value Compiled CSS style css root sm value lg value Whenever you see that it returns value in CSS just interpolate it style scss use type as root each key value in type scale key value Now out of nowhere you will get an error saying it is not valid CSS Becuase key is returning screen sizes sm lg and value is trying to return another map inside those keys Let s create one more each and see what it will return Dont forget that value is returning inner map so the second each should be relative to value style scss root each screen size sizes in type scale each key value in sizes fs key value If you remember in the first layer of each key returned screen sizes sm lg and value returned another map containing all the sizes of each key So I called key as screen size and value as sizes Now in our inner each rule we are asking it to return keys and values inside those sizes Compiled CSS style css root fs rem fs rem fs rem fs rem fs rem fs rem fs rem fs rem fs rem fs rem Okay we are getting there A few things left to do Now we need to find which key belongs to sm or lg screen sizes And here if and else come very handy So screen size return screen sizes sm lg If it returns sm just return it inside the root Else return it inside the media query You need to use if and else statements after the first layer of each rule not the second If it satisfies return the second layer of each rule that we wrote above style scss use type as root each screen size sizes in type scale if screen size sm each key value in sizes fs key value else media min width em each key value in sizes fs key value Compiled CSS style css root fs rem fs rem fs rem fs rem fs rem media min width em root fs rem fs rem fs rem fs rem fs rem Yes we did it As you might have guessed we can add more screen sizes And it is a task for you if you want to give it a shot If you have any doubts questions or feedback please do consider sharing it with me I really appreciate it and get back to you as soon as possible If you are new to Sass maps and each method I highly recommend checking out Kevin Powell s video where he explained the superpower of Sass with custom properties and utility classes It is where I learned these cool things too Custom props amp utility classes by Kevin PowellThat s it I hope you liked it	2022-08-13 15:04:18
