VIM: simple steps to create syntax highlight file - for logfiles -


I have to go through some (log4j generated) logfiles; I know their nature very well (I mean, I can already use Pass-Pug Reggaeus etc.).

I want to highlight them automatically in VIM when I load them (* .log).

A logfile entry looks like this: 

  YYYY-MM-DD HH: MM: SS, SSS [...] # log-level # [ .] Message ## LOG-LEVEL # Standard 'error', 'INFO', 'DEBUG', 'FATAL' .... and 'YYYY-MM ...' date / Time represents the millisecond resolution.  
 To start with me, what are the steps needed to highlight the date string in the yellow strip with blue text - and whenever the text reads 'error', then in white color There should be a red background with  
 I have tried to go through some tutorials on this, but one can not find that which is quite simple to understand, so I am here after some real basic steps!  
 Cheers  
 Edit: Based on the instructions given below, here's a summary of what I did:  
     
  1.  
     Syntax file 'Log.vim' was created IN .vim \ syntax (see below for example content).   
  2.  
     A file was created in .vim \ ftdetect \ log.vim with the following content:  
     AU BufRead, BufNewFile * .log set file type = Log   
  3.  
     Make sure that my startup settings have the following:  
      syntax on file type>   
      
     
     
     There are three ways to define syntax items (see : help: Syn-define ): 
     
       
    •  Keywords: These items are for the simple st of the keyword characters The ring is I. It is the fastest mile. 
      •  
    •  Mail: There are regular expressions for these matches. 
      •  
    •  Areas: These are for long areas which have the possibility of other items. 
      •  
     
     There are many arguments that make things even more complex (with the match within the field), see : help: syn-arguments  on this For discussion. 
     
     is a priority that comes in effect (see : support: sync prioritization ). 
     
     The color is controlled by the highlight command and the syntax is different from the command. 
     
     An easy way to get started is to use a match to find dates and keywords to detect the error. Then use the highlight in the colors to come in life: 
     
      "This creates a keyword error and puts it in the highlight group that logarre: syn keyword log error error" Creates matches and puts them in Highlights group called "Next Group and Squiwite seeks Wim for log time after match: Sync Mail LogDate / ^ \ d \ {4} - \ d \ {2} - \ d \ {2} / nextgroup = logTime skipwhite "It creates a match time (but only Ga occurs after the date): syn match matchtime / \ d \ {2}: \ d \ {2}: \ d \ {2}, \ d \ {3} / "now reveal them:" the link just Login to the link "Error to fill the error for the error Hi Link Log Error Error" Def means the default color - can override the colors hi def logDate guibg = yellow guifg = blue hi def logTime guibg = green guifg = White  
     
     all in / .vim / syntax / log.vim and ensure that the file type is set correctly (see : help filetype.txt ) - e Sector should automatically load. 
     
     Hopefully you should walk with something. Read the various sections (very slowly) of : help syntax.txt  and : help usr_44.txt  for more information.

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
