programming ON my android phone (etc)

Greetings gentlefolks.
This forum has been an absolute godsend. I managed to get the latest JF os installed and as such am thoroughly enjoying my G1.
In the past, I had a Windows Mobile phone from HTC. One of my favorite applications on it was Pocket Scheme because it enabled me to write code ON my phone. I'd love to eventually spend time working on software FOR my G1, but right now I'm interested primarily in writing code while on the train, in line, etc.
As far as I know, Pocket Scheme is not available on the Android. I also came across Ruby for Android [2], but so far it force closes as soon as I open it.
So:
1. Are there any languages that are available for writing code on the android? Something with either an included editor AND repl (like Pocket Scheme) or even just an editor (?) or a repl (like Ruby for Android) would be fine.
2. What editor for making "plain text" files with any extension do you use?
3. In desperation I tried using echo to create a new shell script file the other day, and Android OS complained that the file system was read only. Can I make it r/w from within the android, or do I need to use ADB?
Thanks in advance. I tried googling for answers, but to no avail.

Well you could flash Debian to a JF build and go from there.

You can remount it as r/w from the device. I can't remember exactly what the command is but it is something along the lines of "mount -oremount,rw /dev/block/mtdblock0 /system" anyone care to correct me if that is wrong? You can also use DroidSans Tweak Tools available free in the market, just don't use the lite version

almosst correct on the command there, there is actually a space between the "-o" and "remount" so it should read
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
that would make your system partition read write, but if you wanna run shell scripts i would go grab gscript and just write them in there.
oops i typed it wrong i switched the rw and remount, it's fixed now sorry

Haha that's funny. Ive been typing: "mount -o rw, remount -t yaffs2 /dev/block/mtdblock3 /system"
But. That's just what works for me. Found it when I first rooted my phone.

[Q] Command to install apps from terminal.

Sorry if this has already been asked. I tried searching and couldn't seem to find clear terminal commands. All of them either didn't seem to work, or were actually adb commands.
What are the exact commands for installing an app through terminal?
I'm trying to find the easiest commands to help a friend that needs to install an app on his phone. He doesn't have a data plan so he can't go into the market to install it, and isn't near the computer for adb.
I've used this command set before to install an app to system before:
su
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
cat /sdcard/'name-of-app'.apk > /system/app/'name-of-app'.apk
mount -o remount,ro -t yaffs2 /dev/block/mtdblock3 /system
But that is a little to complicated for him, and would be especially hard to explain over the phone, because like I said, he has no data plan.
Now I've seen this command around here:
su
cd /sdcard
install 'name-of-app'.apk /system/app/'name-of-app'.apk
But I tried that on my phone before giving it to him and it didn't seem to work.
So what are the commands for installing an app through the terminal to either system or data?

Install the sdk...
adb install application.apk
Sent from my HTC Liberty using XDA App

You just have to copy the application to /system/app (cp command), /system/ has to be mounted first of course.

TypeFresh good to go on 2.1?

As the title states, is TypeFresh good to go on rooted 2.1 on an X10i? The huge fonts are killing me

It wouldn't reboot for me so I've just used RootExplorer instead.

It worked fine for me, both apps (Typefresh and Andexplorer) where installed from the market.

Thanks for all the links my friend.

I always use this method to change my fonts:
1. I pick the font I want and I copy the regular and bold version on my SD.
2. I rename the regular to DroidSans.ttf and the bold to DroidSans-Bold.ttf.
3. Then, on my phone, using a Terminal application, I type:
su
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
chmod 4755 /system/fonts/DroidSans.ttf
dd if=/sdcard/DroidSans.ttf of=/system/fonts/DroidSans.ttf
chmod 4755 /system/fonts/DroidSans-Bold.ttf
dd if=/sdcard/DroidSans-Bold.ttf of=/system/fonts/DroidSans-Bold.ttf
4. Reboot!
5. Enjoy!!

I tried to change it by the Terminal but it says adb not found.Please help how can I overcome this problem.

If you can't get Typefresh to reboot please try the following: Install the latest Busybox from the market. This fixed the problem for a friend of mine.

good for i think there is some problem with my root, type fresh says cannot remount system. which root method did you use. i recently updated my x10i to 2.1 global generic and rooted with one click 1.5. titanium says ok and su too working. but still i cannot wrewrite or copy paste files. help will be appreciated.

I used the same method. The first time you run Typefresh you have to give permission, this will cause Typefresh to 'cannot remount sytem' , when you retry it works

Ooops...! Sorry! My bad! The correct commands are:
su
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
chmod 4755 /system/fonts/DroidSans.ttf
dd if=/sdcard/DroidSans.ttf of=/system/fonts/DroidSans.ttf
chmod 4755 /system/fonts/DroidSans-Bold.ttf
dd if=/sdcard/DroidSans-Bold.ttf of=/system/fonts/DroidSans-Bold.ttf

Hi.It works like a charm.Thanks for sharing!

Or just copy and paste using RootExplorer or similar. TF can be a bit temperamental at times, was in 1.6 and is in 2.1.

works perfectly for me... running sony sketch..... no more large letters in 2.1

i5500 Rooted, BusyBox, But Where Can We Go From Here?

OK, so got a nice shiny new Europa/i5500 today...
Yea, as you can imagine the first thing on the list was rooting. Done.
Not much you can do with just a root so thought to hell with it time to start poking around.
ADB has issues, cant remount from command line so it needs doing by adb shell > su.
Code:
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
Code:
dd if=/sdcard/busybox of=/system/bin/busybox
chmod 4755 /system/bin/busybox
mkdir /data/busybox
/system/bin/busybox --install -s /system/bin/
Busybox sorted!
But now what is there?
Had a poke around and there seems to only be one thread regarding the phone (which tbh is quite nippy considering its size and has some potential).
Doe's anybody have any sort of information on building custom roms from AOSP for this? What kind of drivers need to be sorted?
I hate to think that the most we will ever do to this little gem is custom themes since for it's size it is a damn impressive bit of kit as far as my experience has been so far...

:Update:
I wasn't keen on the apps drawer not being alphabetised so tried pushing TouchWizz30Launcher.apk from Vibrant which was suggested for for the Fascinate and it works perfect, heads up for anyone else who has this niggle.
Apps2SD also works fine but had to partition SD using PC since no parted available on phone...
Strike that, Market Icon is now missing from AppDrawer... reverting back to stock lol

Can't remount /system in read-write mode.

Yes, my phone is a chinese Hero H2000+.
I have managed to stick su and busybox into /system/bin using debugfs, but there's absolutely no way I could find to make /system get into read-write mode.
If I type "mount -o rw,remount /system" it seems to work for about 1 second, but then it's remounted read-only. All the changes will be reverted (files I add/remove via script). If I try to run the same command again, it will show me a message saying filesystem is read only.
Does anyone know what might be causing this?
Thanks in advance.
