How make personal library for Processing.

in Library and Tool Development • 5 months ago

I'm trying to create a simple library in order to remove some Tab of my Processing IDE and because i dont need to edit this classes. I work with processing 2+.

I tried to "Sketch > Add file" after doing my .jar, but it don't work, i get the normal error message meaning that it can't find the needed library

I tried to make library manually with the good folder architecture, and with the "package ExcelReader" at the top of each java script:
      - Sketch
            - libraries
                  - ExcelReader
                        -library
                              - ExcelReader.jar
                        - library.properties
                        - src
but i get the same error than before, it dont find the library and tell that i must place it in a folder named libraries.

And finally, i tried with the Eclipse way, i get a Successfull Compillation but when i place my ExcelReader lib in libraries folder and write "import ExcelReader;", i get a new error:

java.lang.StringIndexOutOfBoundsException: String index out of range: -1
    at java.lang.String.substring(String.java:1937)
    at processing.mode.java.JavaBuild.preprocess(JavaBuild.java:430)
    at processing.mode.java.JavaBuild.preprocess(JavaBuild.java:185)
    at processing.mode.java.JavaBuild.build(JavaBuild.java:144)
    at processing.mode.java.JavaBuild.build(JavaBuild.java:123)
    at processing.mode.java.JavaMode.handleRun(JavaMode.java:114)
    at processing.mode.java.JavaEditor$19.run(JavaEditor.java:472)
    at java.lang.Thread.run(Thread.java:680)

I cant get it, i dont understand why this own library cant get work. If i try to put controlP5 at the same place, it work, so i wonder if my library is correct. So where could come from the problem?! Any idea?

Thanks.

Now the second method (doing ExcelReader folder myself) return the same error than doing it with Eclipse (library template) :

java.lang.StringIndexOutOfBoundsException: String index out of range: -1

I tried to "Sketch > Add file" after doing my .jar

In your sketch folder create a folder called 'code' and place the jar inside that. If that didn't work then there is probably something wrong with the jar.

And finally, i tried with the Eclipse way, i get a Successfull Compillation but when i place my ExcelReader lib in libraries folder and write "import ExcelReader;", i get a new error:

Are you using the library template? If so then Eclipse should be placed in the correct place during the build process. Since you appear to doing this manually then you probably have not edited the build.propeties file in the resource folder.

If so then Eclipse should be placed in the correct place during the build process.

I used Eclipse to do a try but i use Processing IDE and when i take the ExcelReader folder (lib) and put it in my project > libraries folder, Processing dont find it.

Is there a way to corrupt a .jar? I used the bash command

jar cvf ExcelReader.jar Class1.java Class2.java ...

Since you appear to doing this manually then you probably have not edited the build.propeties file in the resource folder.

By doing it manually i didnt notice a build.properties files, i only see it with Eclipse way.

I'll do some test again tomorrow but i'm a little confused, i dont understant everything i'm doing and just try to follow tutorial.

If you want to create a library using Eclipse then you will find links to instructions on how to do it here.

Ok, i have try again with eclipse and i continue to get the same error when i launch my project in Processing (2+).

java.lang.StringIndexOutOfBoundsException: String index out of range: -1
    at java.lang.String.substring(String.java:1937)
    at processing.mode.java.JavaBuild.preprocess(JavaBuild.java:430)

    at processing.mode.java.JavaEditor$19.run(JavaEditor.java:472)
    at java.lang.Thread.run(Thread.java:680)

I've edit build.properties and now eclipse export the ExcelReader lib directly in my libraries folder in my sketchbook.
I get a library folder with core.jar and ExcelReader.jar, a src folder with my .java classe, and 2 other folder (examples and reference).

I dont know where i make a mistake, and i dont understand what param could cause this error.
I've followed your link step by step.

My package explorere:

the 4 param point from build.properties

sketchbook.location=${user.home}/Desktop/giroscopie
#classpath.local.location=${user.home}/Documents/workspace/libs (commented)
java.target.version=1.6
project.name=ExcelReader

and i've no error or notice in my script, i gave the good package and make the import.

I think i'm just really bad :'(

Now i get

No library found for ExcelReader
Libraries must be installed in a folder named 'libraries' inside the 'sketchbook' folder.

Lol, i'm sorry

edit: It's when i try to use "code" folder that i get the string index error ..

edit': ok it works, i just delete "code" folder wich occur and error, copy past the de-zipped folder from distribution folder in my libraries folder, and use the "import lib" tool. And it's ok.

edit'': Ahaha, not compatible with processing.js :D so i just do a useless thing!

Thx for your help.
