My requirement is simple. At the beginning of each file there should be a block comment like this:
/*
* This file was last modified by {username} at {date} and has revision number {revisionnumber}
*/
I want to populate the {username}, {date} and {revisionnumber} with the appropriate content from SVN.
How can I achieve this with NetBeans and Subversion? I have searched a lot but I can't find exactly what I need.
I looked at this question and got some useful information. It is not exactly duplicate because I am working with NetBeans but the idea is the same. This is my header:
/*
* $LastChangedDate$
* $LastChangedRevision$
*/
Then I go to Team > Subversion > Svn properties and add svn:keywords as property name and LastChangedDate LastChangedRevision as property value.
And when I commit from NetBeans it looks like this:
/*
* $LastChangedDate: 2012-02-13 17:38:57 +0200 (Пн, 13 II 2012) $
* $LastChangedRevision: 27 $
*/
Thanks all for the support! I will accept my answer because other answers do not include the NetBeans information. Nevertheless I give +1 to the other answers.
As this data only exists after the file was committed it should be set by SVN itself, not a client program. (And client-side processing tends to get disabled or not configured at all.) This means there is no simple template/substitute like you want, because then after the first replacement the template variables would be lost.
You can find information abut SVN's keyword substitution here. Then things like $Rev$ can be replaced by $Rev: 12 $.
You can do this with The SubWCRev Program.
SubWCRev is Windows console program which can be used to read the
status of a Subversion working copy and optionally perform keyword
substitution in a template file. This is often used as part of the
build process as a means of incorporating working copy information
into the object you are building. Typically it might be used to
include the revision number in an “About” box.
This is typically done during the build process.
If you use Linux, you can find a Linux binary here. If you wish, you could also write your own using the output of svn log.
I followed Petar Minchev's suggestions, only I put the $LastChangedRevision$ tag not in a comment block but embedded it in a string. Now it is available to programmatically display the revision number in a Help -> About dialog.
String build = "$LastChangedRevision$";
I can later display the revision value in the about dialog using a String that has all of the fluff trimmed off.
String version = build.replace("$LastChangedRevision:", "").replace("$", "").trim();
I recommend a slightly different approach.
Put the following header at the top of your source files.
/*
* This file was last modified by {username} at {date} and has revision number {revisionnumber}
*/
Then add a shell script like this
post update, checkout script
USERNAME=# // use svnversion to get username
DATE=# // use svnversion to get revisio nnumber
sed -e "s#{username}#${USERNAME}#" -e "s#{date}#${DATE}#" ${SOURCE_CONTROL_FILE} > ${SOURCE_FILE}
pre commit script
cat standard_header.txt > ${SOURCE_CONTROL_FILE}
tail --lines $((${LENGTH}-4)) ${SOURCE_FILE} >> ${SOURCE_CONTROL_FILE}

i got this result in the console:
But I want to get the table view and save to database. Which command can I use to get the table view ?
Table view:
any help please ?
If you can clarify why you're trying to generate the data this way, I or others might be able to give better advice.
There is no single NetLogo command or NetLogo API method to generate that table, you have to use BehaviorSpace to get it. Here are some options, listed in rough order of simplest to hardest.
Option 1
If possible, I'd recommend just running BehaviorSpace experiments from the command line to generate your table. This will get you exactly the same output you're looking for. You can find information on how to do that in the NetLogo manual's BehaviorSpace guide. If necessary, you can run NetLogo headless from the command line from within a Java program, just look for resources on calling out to external programs from Java, maybe with ProcessBuilder.
If you're running from within Java in order to setup and change the parameters of your BehaviorSpace experiments in a way that you cannot do from within the program, you could instead generate experiment XML files in Java to pass to NetLogo at the command line. See the docs on the XML format.
Option 2
You can recreate the contents of the table using the CSV extension in your model and adding a few more commands to generate the data. This will not create the exact same table, but it will get your data output in a computer and human readable format.
In pure NetLogo code, you'd want something like the below. Note that you can control more of the behavior (like file names or the desired variables) by running other pre-experiment commands before running setup or go in your Java code. You could also run the CSV-specific file code from Java using the controlling API and leave the model unchanged, but you'll need to write your own NetLogo code version of the csv:to-row primitive.
globals [
;; your model globals here
output-variables
]
to setup
clear-all
;;; your model setup code here
file-open "my-output.csv"
; the given variables should be valid reporters for the NetLogo model
set output-variables [ "ticks" "current-price" "number-of-residences" "count-years-simulated" "solar-PV-cost" "%-lows" "k" ]
file-print csv:to-row output-variables
reset-ticks
end
to go
;;; the rest of your model code here
file-print csv:to-row map [ v -> runresult v ] output-variables
file-flush
tick
end
Option 3
If you really need to reproduce the BehaviorSpace table export exactly, you can try to run a BehaviorSpace experiment directly from Java. The table is generated by this code but as you can see it's tied in with the LabProtocol class, meaning you'll have to setup and run your model through BehaviorSpace instead of just step-by-step using a workspace as you've done in your sample code.
A good example of this might be the Main.scala object, which extracts some experiment settings from the expected command-line arguments, and then uses them with the lab.run() method to run the BehaviorSpace experiment and generate the output. That's Scala code and not Java, but hopefully it isn't too hard to translate. You'd similarly have to setup an org.nlogo.nvm.LabInterface.Settings instance and pass that off to a HeadlessWorkspace.newLab.run() to get things going.
I am working on a Java project to parse logs where I am using Java Grok library for pattern recognition. I have given the pattern as follows:
%{SYSLOGTIMESTAMP:syslog_timestamp} %{SYSLOGHOST:syslog_hostname} %{DATA:syslog_program}(?:\\[%{POSINT:syslog_pid}\\])?: %{GREEDYDATA:syslog_message}
When I try parsing the line,
Dec 23 14:30:01 louis CRON[619]: (www-data) CMD (php /usr/share/cacti/site/poller.php >/dev/null 2>/var/log/cacti/poller-error.log)
it gives the following output:
syslog_timestamp=Dec 23 14:30:01
syslog_hostname=louis
syslog_program=CRON
syslog_pid=619
syslog_message=(www-data) CMD (php /usr/share/cacti/site/poller.php >/dev/null 2>/var/log/cacti/poller-error.log)
I want to extract details from the syslog_message further to get stuff like facility and severity. How can I improve the grok pattern to get these details?
I am not an expert of Java Grok. You can use www-data as your facility and error as your severity.
Change your pattern to get this information.
syslog_facility=www-data
syslog-severity=error
Regards,
Ivo
As far as I see, you can't get the severity and facility from that message because it's not there. Assuming this is written by a syslog daemon, and assuming that syslog daemon is rsyslog, you can change the way things are written down by altering the template and select the properties you want.
You can write, for example, one JSON per line in a file with a template like this (basically copy-pasted from this rsyslog->Elasticsearch blog post):
template(name="jsonPerLine"
type="list") {
constant(value="{")
constant(value="\"#timestamp\":\"") property(name="timereported" dateFormat="rfc3339")
constant(value="\",\"host\":\"") property(name="hostname")
constant(value="\",\"severity\":\"") property(name="syslogseverity-text")
constant(value="\",\"facility\":\"") property(name="syslogfacility-text")
constant(value="\",\"tag\":\"") property(name="syslogtag" format="json")
constant(value="\",\"message\":\"") property(name="msg" format="json")
constant(value="\"}\n")
}
This way, in your application you can parse this JSON and get all these fields, which is much cheaper than using regular expressions (which is what grok does).
You'd use this template to write to files later on in the configuration, for example:
action(
type="omfile"
file="/var/log/json_messages"
template="jsonPerLine"
)
If you get errors from the syntax above, it may be that your distro has a really-really old version of rsyslog. If that's so, you can get packages from the official repositories.
UPDATE: Made a posting on the Gradle forum. Please star this issue so that it gets more attention http://gsfn.us/t/4jedo
I'm in the process of transitioning from a primarily Ant build environment into a Gradle one. One sticking point is injecting Google Analytics and Adsense code into the JavaDoc. This is done by putting java script code into the header or bottom panels. For an example of what I'm currently doing, look at this question CDATA.
The problem with Gradle is that it can't handle newline characters in the string which is to be inserted. If you filter out those characters you break the script. Here is a code sniplet:
task alljavadoc(type: Javadoc) {
source = javadocProjects.collect { project(it).sourceSets.main.allJava }
classpath = files(javadocProjects.collect { project(it).sourceSets.main.compileClasspath })
destinationDir = file("${buildDir}/docs/javadoc")
configure(options) {
header = "this is\na test which should fail"
}
}
The critical part is "header =". If you remove the '\n' character it will work just fine. Otherwise the call to javadoc, which Gradle makes, will fail with the following error:
Successfully started process 'command '/opt/jdk/jdk1.7.0_21/bin/javadoc''
javadoc: error - Illegal package name: ""
javadoc: warning - No source files for package a
javadoc: warning - No source files for package test
javadoc: warning - No source files for package which
javadoc: warning - No source files for package should
javadoc: warning - No source files for package fail
The actual java script that I wish to include is below. Note that I can't hack it by removing new line characters since that will break the script.
<script async src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>
<!-- banner -->
<ins class="adsbygoogle"
style="display:inline-block;width:468px;height:60px"
data-ad-client="ca-pub-xxxxxxxxxxxxxxxxx"
data-ad-slot="xxxxxxxxx"></ins>
<script>
(adsbygoogle = window.adsbygoogle || []).push({});
</script>
As a sanity check I also passed in a string with new line characters directly to javadoc (manual) on the command line and it works just fine.
javadoc foo.java -header "This is a test
and so is this"
The output HTML:
<div class="aboutLanguage"><em>This is a test
and so is this</em></div>
</div>
I have an explanation, but i don't have a solution except for creating a new feature request in Gradle JIRA.
To generate a javadoc Gradle first generates the so-called argfile at build\tmp\javadocTaskName\javadoc.options that contains all individual options and than executes javadoc #full\path\to\build\tmp\javadocTaskName\javadoc.options command.
It is actually quite useful as you can debug the contents of that file by simply invoking javadoc #javadoc.options yourself from the command line.
It is possible to define multi-line values in the argfile by using the \ character at the end of each line inside the multi-line value.
The example header = "this is\na test which should fail" results in
-header 'this is
a test which should fail'
but we need to get
-header 'this is\
a test which should fail'
to tell javadoc that the value continues on the next line.
Now the problem is how to output that \ on each line.
The obvious attempt at header = "this is\\\na test which should fail" does not work, it will result in
-header 'this is\\
a test which should fail'
And even Groovy multi-line or slashy strings will not work and will result in similar double back slashes.
Because Gradle just replaces all single backslashes in the option values. The JavadocOptionFileWriterContext.writeValue(String) method is the culprit, the replaceAll("\\\\", "\\\\\\\\") line in particular (a regex that matches single backslash and replaces it with double backslash ).
This escaping is required for backslashes inside a line, but it should not escape a single backslash followed by the new line character. My regex-fu is not strong enough to write such a pattern, but it is surely possible.
Or even better, the escaping mechanism inside that method should replace newline characters with a single backslash followed by the newline to hide all this stuff and allow users to declare multi-line javadoc options without the need to think or even know that feature.
I would appreciate if somebody can create an issue in Gradle tracker as i can't do so from my current location. This sentence should be replaced with the link to the issue so that people with similar problem can vote and track its progress.
I tried to implement it in Gradle but I couldn't get it to work reliably on windows. If the options file has this:
-header 'this is\
a test which should fail'
It works nicely on linux/mac but fails on windows (tried on win7/java7 and some other windows+java6). I've tried with vanilla javadoc executable (without Gradle).
I'll get the fix into Gradle and it will work out of the box for linux/mac but not quite for windows. If you want to help out with windows support catch us at http://issues.gradle.org/browse/GRADLE-3099
I am using SVNKit to checkout svn base repository. Earlier I was using checkout to head for that purpose I was using SVNRevision.HEAD. It was working fine without issue.
below is the syntax of same and revision.Head was used in case of checkout to Head.
doCheckout(SVNURL url,File dstPath,SVNRevision pegRevision,SVNRevision revision, boolean recursive)
but let say if I have to checkout to a specific revision for example 27988, what should be value of pegRevision parameter ?
I am confused please help, I tried HEAD/BASE for pegrevision and also same 27988 etc but it gives error like URL not exist etc .
Just an update, problem was with my code revision was going as 0 always due to some logic issue hence SVN URL was not found and giving error. I tried now with HEAD as pegRevision and 27988 revision works just fine. Thanks!
Well, first, you have to specify an SVNRevision, not an integer.
long targetRev = 27988;
SVNRevision revision = SVNRevision.create( targetRev );
doCheckout(...
As for pegRevision, you almost certainly want SVNRevision.HEAD. As the docs specify, it is:
the revision at which url will be firstly seen in the repository to
make sure it's the one that is needed
So, HEAD is usually sufficient. When it's not, things get complicated (and very specific), see the svn book.
I want to develop a java cli with jline..I get different Jline version from Internet, but I don't know the difference between them..
My OS is WINDOWS XP SP2.
In Jline09.9 and Jline1.0, it also don't support clean screen. How to config keybind to support clean screen??
The source code WindowsTerminal.java
/**
* Windows doesn't support ANSI codes by default; disable them.
*/
public boolean isANSISupported() {
return false;
}
In jLine0.9.9 and Jline1.0 , clean screen don't work..
http://i.stack.imgur.com/2m71z.jpg
In Jline2.x, it support clean screen, but console appear gibberish when I use array key UP/DOWN/LEFT/RIGHT , INSERT, DELETE, END..
Bad code and strange Character in Jline 2.6 and Jline2.9 When type array key or DELETE,HOME,INSERT key
http://i.stack.imgur.com/5A8d2.jpg
I don't know how to config keybind in Jline1.x and Jline2.x through keybinds.properties.
And How to config the keybinds.properties ? How to use it??
Could you give some advice or example?
Did you install AnsiConsole? This is needed to render the "gibberish" escape codes.
AnsiConsole.systemInstall();
should do it for you.
