light weight app for file search and app search

[Manoj Gudi]

As discussed earlier we (pps and myself) developed a rough application for  searching installed applications and file search; 

main features:

1> memory use ~ 8mb  (which is nearly half of earlier application which used pyqt)

2> florence/onboard support

3> runs on gtk2

4> touch optimized (huge buttons)

5> very light dependencies (assuming its run on lxde desktop environment) 

6> Light weight app, weights < 25kb (including glade file)

We request anybody to test it, to obtain it-

> pull manoj branch from https://github.com/manojgudi/py_finder.git

> run dep_install script using root privileges, it installs all dependencies required

> from terminal run UI_GTK.py

currently its on v0.2; it may not be an eye-pleasing application since we have avoided use of fancy buttons with pixbufs to reduce memusage; but definitely its user friendly and straightforward to use

we request to send us bugs reports while we keep adding new features and fixing more errors

Nice :-)
I would suggest you to add a Launch button, say if user has searched bash then in a touch env its
difficult to double click to launch it.

[Manoj Gudi]

thanks for prompt reply

currently clicking on any search result it opens the folder(using pcmanfm) where the file is stored

i have to think how to handle file opening using proper application, probably by reading its extension; but again its lot more complex since lot of user cases have to be handled...

HI Manoj,

Really nice app. Can I know whats running beneath ? is it find  or locate ?

With reference to your second screen shot where `app` button is clicked, it is showing all files related to 'bash'.

I think it should show applications related to bash, you should confine you search to '/usr/share/applications/'.

Also it should find string like *terminal*, *bash* etc.

What do you say ??

[Manoj Gudi]

I think I misread above statements

I should have used a file as keyword instead of using "bash" in the second screenshot. Silly me,

anyway, In app tab, you search your app keyword- 

for example i am looking for term, I will just type term, and it returns lxterminal <v02-2.png>

if i m looking for a particular file, like say mintmenu.deb; I will search it in files tab, it returns me a list of all files and their path names which are relevant

clicking on any path will open the folder (using pcmanfm) where the file resides <v02-1.png>

I hope this clears the confusion...

updates

If somebody can test and lemme know...

Launch button is necessary? If we can make the display tiles clickable and also display the icons ?

[Srikant]

in that case launch buttpn is not reqd

I am reducing the number of folders the file search will scan through to '/home/' , I realised that it wont scan through the Memory card. So I needed to confirm wether the location of the memory card is at '/media/' or something else?

[Srikant]

In 12.10 which we are using now it will be /media/aakash/

[Manoj Gudi]

In file searching we use locate command in the backend, which is giving us inaccurate searches

I believe it searches the indexes instead of inodes

so this search doesnt show recently created file/stt

Any better alternatives except "find"?

[Srikant]

hmm..not really..Sachin what you say ?

--
 
 

[isachin]

I think 'find' is much better than 'locate'. Ya its true that 'locate' does indexing and search within the index.

The newer file takes time, as a result they cant be located as soon as the file is created. This is all done by 'updatedb'.

I think you should try 'find'  with -*time flag(man find). Even 'ls -lt' will show recently created/modified at the top.

You should give first preference to user HOME and then to other locations

If you are uncomfortable with 'find', then the silly hack is to run 'sudo updatedb' first n then do 'locate' but this will consume time. 

what say ?

--

Sachin

[Manoj Gudi]

We refused "find" because its resource intensive and much slower than locate

But sudo updatedb doesn't seem as viable option either

Will search for other options before settling for find..,

[Pranav Salunke]

I am trying out os.walk ... if it turns out to be light enough then we don't have to worry. The problem with locate command is that in case the External Device is Fat32 or NTFS , it wont be able to scan through. I dont know how many more formats the same issue will arise.

[Manoj Gudi]

while pps works on making file search better, I added a new feature:  5 recent keywords done by user will be available on a separate tab

there are two sections for files and apps for recent searches <v0.4-1.png>

clicking on any keyword will take user to corresponding tab, for example I clicked on pid, and it took me to app tab <v0.4-2.png>

each unique and result oriented keyword is saved in local .data.xml file

this commit for v0.4 has relatively huge offset of around 450lines change in code base; 

any weird behavior with application is of course a feature

The RAM usage has upped to around 16mb on avg along with florence keyboard instance running

without that it is around 9mb

still much less than what mintmenu's or our original Pyqt app's RAM usage

I think this is should be it for features to be added...

we'll from now try to make it more stable, fix bugs and reduce memory overhead

I request to involve few testers since feedback will help us better this.

To test this application, pull pygtk_stage branch from https://github/manojgudi/py_finder.git

and a to run dep_install script so that it installs xml libs for python...

[Srikant]

Nice work. Try keeping .data.xml file in .local/ directory. I spoke to that tablet issuing guy, you will
get it on monday morning with 2 sdcards, we have some meeting in the morning..so is it possible
for you to come after 2pm to aero annex lab.

Sure no prob.

[Pranav Salunke]

I have done some work on file searching through os.walk ... i wanted to know how many GB worth storage space will be present in the /home/ and /media/aakash/ folder.
As of now for a 50 gb drive with nearly 25 gb of data (about a few thousand folders and files) it searches instantly ... but for a huge hard disk like my external 700 gb harddisk almost full ... it takes very long time to prune through the filesystem.

we are reaching near stable version, the current v0.6 has following updates:

1> updated documentation

2> installation scripts

3> its ready to be integrated with lxpanel, Just click on Add Application Launch bar, and select Py Finder (see README.md)

and lots of other minor features and improvements in search functionality by pps

it can be pulled from tag v0.6

If u get time, give it a go

[Srikant]

great :-)
Tomorrow also your tablet issue stuff not possible, everyone is busy with Mr.N K Sinha's visit, lot of demos and etc..so plz consider it on 29th

[Manoj Gudi]

Okay no problem

[Manoj Gudi]

Attached Screenshots..

integrated with custom icon

[Srikant]

looks great :-)

[Manoj Gudi]

py_finder installation script installs  /home/username/.py_finder

pps thinks it should be other folder like /usr/local or /usr/share

I primarily disagree with this since user cannot fiddle with scripts without getting sudo privileges

what is the best path to install ?

[Srikant]

If they are only installation files then it should goto system dirs, where does lxde keep its plugins?? keep them in the same directory

>> lxde keeps all (and only) its .desktop files in /usr/share/applications/   so probably its not a good place

we are talking about 3 python scripts, and 1 bash script with few other icon files as our installation files...

[Srikant]

if they are scripts then they should go in system location..user can change them any way with root
permissions...

[Manoj Gudi]

I realized I was dragging this small application too much over small details

This app. is ready for mass-use(v0.9) from master branch

https://github.com/manojgudi/py_finder

[Pranav Salunke]

awesome \m/ ... infact none of the software projects are ever complete or can ever be complete ... linux is one good example of the one being every growing and ever changing .... i see it as green. Lets hope we do contribute to an Indian opensource cause.

[Manoj Gudi]

As pointed out in discussion, I rewrote entire search algorithm.

Now, it takes more time to search(~3sec), but results are good

1> search keyword by type/purpose of application

For ex: I want an application to write some document, so I search with keyword "write" and it shows abi-word. This means user need not remember the application name

<modified_search_1,3.png>

2> Search now returns all software packages which have not been installed from repositories like google-chrome etc...

Few finishing touches remain like finding correct icons from set, fixing scrolling etc.. which will be completed soon

[Pranav Salunke]

I should be working on it asap ... will finish the icon touches and try to improve the search time and some more testing...

[Manoj Gudi]

I could no longer take the pain to write cat /sys/class/power_supply/battery/capacity to check battery status hence made a small makeshift battery monitor integrated with lxpanel until I rewrite the applet:

https://github.com/manojgudi/py_batmon.git

thought I should share, solves my problem at least...

[Manoj Gudi]

With pps finally finishing icon search, py_finder is now upgraded to v1.0

with that i've fixed other small annoying problems like dealing with multiple instances etc...

its on master branch, and soon there will be github-pages(http://manojgudi.github.com/py_finder/)

repo: https://github.com/manojgudi/py_finder.git

its tested on aakash, so it should work flawlessly.

[Pranav Salunke]

Has any one checkout Py-Finder v1? Are there any improvements , comments for the app? We both need to learn a lot and some feedback would do great. Thanks in advance.

I have seen what Manoj has shown me at IITB, after that I didn't check. 

@Manoj: Plz send the patch for mapping of power button for screen off

I'm planning to show your contributions to Phatak sir on Monday, let him know what 

you guys have contributed.

1. I know, apologies for goof-up...

2. Significant changes have taken place after I showed you the app (it was v0.6 I think). Anyway you can check as and when you want, no probs.

3. I have the mapping code, but I really want to clean it up before Padamshri Prof. D. B. Phatak takes a look at it.

[Srikant]

I won't show him the code. Just give me a usable version to install, and mapping instructions

Phatak is on Leave till 11th of this month. Will show him as soon as he comes.

12.10-lxde-pyfinder-screen-on-off-aakash-bootlogo-04-02-2013.img.bz2 noticed this on github.com and would like to add -battery-monitor

the battery monitor (batmon) code is at https://github.com/manojgudi/py_batmon.git (it is very light and works as it should)

----------------------------------

In case if one thinks fixing lxpanel battery applet is how god wants us to fix battery-monitor issue, then I have been able to shake things up on that side too:

Here's the git repo of lxpanel on which I am working https://github.com/psipika/lxpanel.git.

It seems simple to tweak battery src by changing ACPI_SYS_POWER_SUPPLY to /sys/class/power_supply/BAT1 and the 

b->percentage variable to read capacity file directly <diff attached below>. 

This is not a clean and perfect way, I'll require sometime to make this tweak perfect. However
1> I am doubtful how to test this on aakash
2> Build environment is complicated and bit bulky with most of devel libs for lxpanel

ideas?

We tested you BM, looks good. 

Few suggestions:

1) Instead of BM icon use a battery icon

2) Show charging and discharging status in the dialog box(next to battery percentage, write in green if charging, red if discharging)

[Manoj Gudi]

It was intended as make shift app, I don't think it should be used;

as soon as I get some time I will recompile lxpanel code to correctly track the capacity file.

[Srikant]

ok, but this is a minor thing, u can do that later. atleast change icon and show charging info in the same dialog

[Pranav Salunke]

Well you can count on me if required , I am eager to do the UI part - iff it is free of Kernel related work.

[Manoj Gudi]

please count yourself in.
https://github.com/manojgudi
check a strange repository called py batMon.

start fixing it.

[isachin]

I just applied your patch, its not working. Can you tell me from which src did the 'diff' with ?.

Even https://github.com/psipika/lxpanel.git don't generate the same diff.

Second thing, we cant change the PATH to #define ACPI_PATH_SYS_POWER_SUPPY   "/sys/class/power_supply/BAT1"

as we dont have ../BAT1 in PATH
