How to work in a Linux VM on a Mac (or Unix familly) ?

with 3 comments

Last week, I spend most of my time on a openSUSE VM (I use parallels for information) in order to do some distro specific job on ooo-build (OpenOffice). It was not the best experience I had on Linux, keyboard layout sucks, especially on copy/paste (CMD-C CMD-V do not have relevant replacement solution on Linux) and also the copy/paste generally sucks as I am addicted to JumpCut (clipboard buffering). Then I re-thought about it and found better ways to handle work on a VM and avoid being home sick !! Let me share with you some tips :

iTerm (ssh -X) + Parallels (openSUSE VM) + X11 (OpenOffice from the VM)

iTerm (ssh -X) + Parallels (openSUSE VM) + X11 (OpenOffice from the VM)

  1. Use remotely !
    That’s maybe the main tip, as all others tips are detailed application of these tip. If some of you use to server admin, just treat you virtual machine as just another server.
  2. Do not use a term in the VM use ssh instead .
    That’s a start. Why use a terminal in you VM instead of the terminal you are used to ?
  3. Use Xforwarding as much as possible, Macs come with X11.
    ssh -X can save you sometime. For example, once connected to my VM, ssh -X user@myvm, I can run soffice with display on the Mac side.
  4. Create shorcuts for ssh connection in ~/.ssh/config
    Here is a extract from my ~/.ssh/config :

    Host *
      ControlMaster auto
      ControlPath ~/.ssh/master-%r@%h:%p
    Host suse
      User someUser

    You can use it whenever ssh is involed : ssh suse  or  scp myfile suse:~/someDir
    You can also mix that with public key identification instead of the ControlMaster.

  5. Be lazy, create an alias in ~/bash_profile
    ~/bash_profile is source at the start of a term session, if the file is not present, create it.
    alias suse=’ssh suse -X’;export suse
  6. You need something more persistant than a ssh session ? Use screen
    screen (man screen), is a terminal emulation allowing you to create session and then detach from it, reatach later on.
    basic usage is :
    screen -S ascreenname
    key binding : ctrl-a ctrl-d   # (detach)
    screen -r -d ascreename    # (retach)

    that’s really usefull when you want to create a persistant session or plan to suspend you virtual machine.
  7. You need to access regularly your file from the Mac in your VM ? (vis et versa) Use sshFs
    More information about Ssh FileSytem  :
  8. Use your favorite text editor.
    Mine is BBedit, then I can do things from command line like
    bbedit sftp://suse/
    I am pretty sure you favorite text editor can do those trick as well. Else check TextWrangler.
  9. [that’s some amount of awesomeness, maybe update your blog? 😉]

  10. Always use your favorite text editor.
    I was talking with Thorsten about strange but awesome behaviors of MacOS applications lately, I just learn that MacOS apps using the Cocoa Framework is « able to glean the current display context when run from the shell ».

    By using this capability, and a custom script, we can use BBedit directly from the virtual machine.

    1. Let add some lines to the Mac ~/.ssh/config:

      Host suseroot
        User root

      That’s way more friendly if bbedit can edit file on the VM as root.
    2. Let add some lines to the VM ~/.ssh/config:

      Host suseroot
        User myMacUser

      You should also add a config file in /root/.ssh/config if you want to use it from the root account on the VM.
    3. Last step, let create a executable file /usr/bin/bbedit (chmod a+x /usr/bin/bbedit) with this content:

      d=`dirname "$1"`
      if [[ ! ${d:0:1} == "/" ]]; then d=$PWD/$d; fi;

      ssh mac 'bbedit -w sftp://suseroot/'$d/`basename "$1"`

    4. Now you can use bbedit as an editor on the VM directly, example : bbedit someFile.
      You can even use bbedit (/usr/bin/bbedit) as the standard EDITOR for your virtual machine, thanks to the -w option, example :

      export EDITOR=/usr/bin/bbedit
      crontab -e

    That’s all (now I really think that’s all), If you see something else, feel free to post some comments. 😉

How to install the SDK and compile the C++ examples on MacOS Intel

leave a comment »

This post is a MacOS oriented Hello-world based of this wiki page You can have it in French also


Good news, to start extending OpenOffice using UNO , like create components or extensions, you don’t necessary need to go trough a full build of the source code (I will talk later about the process) which take once start 6h30 on my MacBook Pro. Today, let’s be lazy.

  1. Requirements
  2. Get the SDK and you can drag and drop anywhere, that does not matter.
  3. Test the SDK
    Open a terminal ( or, look for the OpenOffice.org3.1_SDK folder :

    cd <....>/OpenOffice.org3.1_SDK
    #-- And set the environment. Follow the instruction, nothing special here, just some settings.
    #-- You will need to execute this command each time you want to work with the SDK.
    #-- Now go to examples :
    cd examples/cpp/DocumentLoader
    #-- and build
    #-- A few set of instruction will be displayed at the end of the build, Let's follow them. First start OpenOffice
    soffice "-accept=socket,host=localhost,port=2083;urp;StarOffice.ServiceManager" &
    #-- and execute :

    If everything went fine, you should see a new document, with the content of OpenOffice.org3.1_SDK/examples/cpp/DocumentLoader/test.odt.

Just enjoy, you can now extend OpenOffice with the SDK. For more information,  continue your reading on this page :

How to create a new admin-gen theme in symfony 1.2

with 2 comments

As I got yesterday a deep issue in symfony 1.2, I decided to blog about it in english as I hope I will save a lot of time to somebody else. My issue was : « how to create a theme for my admin-gen ? ».

Most of admin-gen user know this piece of code in generator.yml

  class: sfPropelGenerator
      model_class:           BlogArticle
      theme:                 admin
      non_verbose_templates: true
      with_show:             false
      singular:              ~
      plural:                ~
      route_prefix:          article
      with_propel_route:     1

let’s talk in deep about it and especially about the theme param. Just an info, don’t try with_show, it’s not supported in symfony 1.2 ^^ !

First of all, back to the basis, what is init-admin, what is generate-admin ?



Result :



Result :

entrepriseGeneratorConfiguration.class.php      entrepriseGeneratorHelper.class.php

To be honest, the only difference I see between init-admin and generate-admin is generate-admin is more complete :

  • It creates a routing rules.
  • It creates some helpers.

Anyways, they both works the same way as they will inherit from cache/frontend/dev/modules/autoIndividu and cache/frontend/dev/modules/autoEntreprise for the modules apps/frontend/modules/individu and apps/frontend/modules/entreprise.

OK, let’s go. My first advice :

symfony cc is not enough, it only cleans configuration and basic cache, but not the generated code. Then rm -r cache/* is the best way to handle a clean of the cache.

My second advice is :

changing randomly the theme param value will not get far cause no error is thrown if the theme is missing, as reported in the ticket #6287! Then the correct default value are :

  • default is you are using a propel:init-admin.
  • admin is you are using a propel:generate-admin

Now let’s create a new theme from a existing one.

The documentation says :

Customizing the Theme

There are other partials inherited from the framework that can be overridden in the module templates/ folder to match your custom requirements.

The generator templates are cut into small parts that can be overridden independently, and the actions can also be changed one by one.

Which means you can override parts of the template contained in cache/frontend/dev/modules/autoIndividu/template in apps/frontend/modules/individu/template.

However, if you want to override those for several modules in the same way, you should probably create a reusable theme. A theme is a sub-set of templates and actions that can be used by an administration module if specified in the theme value at the beginning of generator.yml. With the default theme, symfony uses the files defined in $sf_symfony_lib_dir/plugins/sfPropelPlugin/data/generator/sfPropelModule/admin/.

That’s true, but only for a module generated with propel:generate-admin (which btw gets as default theme the value admin). Even if it’s works be aware that have to do a full copy of the theme (no override of the default theme).

Here we do :

# move to root of your project
cd root_of_my_symfony_project
# get the generator's data for symfony 1.2.6
svn export data/generator
#you can delete what you don't need
rm -r data/generator/sfPropelForm*

Now you get pretty much everything you need for a theme available in a propel:init-admin generated module, or a propel:generate-admin generated module:

  • If you want to make a theme for a init-admin :
    cp -R generator/sfPropelAdmin/default generator/sfPropelAdmin/mytheme
  • If you want to make a theme for a generate-admin :
    cp -R generator/sfPropelModule/admin generator/sfPropelModule/mytheme

To activate your theme :

  class: sfPropelGenerator
      model_class:           BlogArticle
      theme:                 mytheme
      non_verbose_templates: true
      with_show:             false
      singular:              ~
      plural:                ~
      route_prefix:          article
      with_propel_route:     1

Enjoy the advanced admin-gen customization and feel free to ping me in comments if you need more info or if you see something, you are much welcome 😉
