Display format/color text on the shell

-
Terminals can display texts in color as well as allow formatting with the help of escape sequences.

Escape Sequence = Escape Character + FormatCode+'m' = "<esc>[FormatCodem"

Escape character can be '\e', \033, \x1B

The format code for Red is 31, so to print the Text in Red.

echo -e '\033[31mHello World'

The -e option of the echo command enable the parsing of the escape sequences.

If you want the background to be Red the format code is 41.

echo -e '\033[41mHello World'

We can add multiple format codes with a ; as delimeter

 echo -e '\033[42;31mHello World'

To remove all formatting, the format code is 0.

echo -e '\033[31mHello \033[0mWorld'

It is better to add \033[0m at the end of each colored text.

To Bold the text, the format code is 1.

echo -e '\033[1mHello World'




You can find more format codes in the below link:

bb.utils.contains yocto

Image
bb.utils.contains  is most commonly used function in Yocto. grep in poky directory returned with 696 count. $ grep -nr 'bb.utils.contains' poky/ | wc -l 696 It's definition is present in 'poky/bitbake/lib/bb/utils.py' file This function returns third argument if the second argument is subset of the first argument else returns fourth argument Let's take an example to understand this. You can see from the above screenshot, when the second argument is a subset of first argument, "present" was returned, else "notpresent" was returned We can also use bb.utils.contains inside if loop. This we can use inside a recipe. if ${@bb.utils.contains('SOMEFLAG','NEWVALUE3','true','false',d)}; then     FOO = 'HELLO' fi

Difference between RDEPENDS and DEPENDS in Yocto

-
We normally observe these two (RDEPENDS and DEPENDS) whenever we open any recipe. What should we choose when we write our own recipe. DEPENDS -> Build Time Dependency RDEPENDS -> Run Time Dependency DEPENDS: When a recipe 'A' is DEPENDS on recipe 'B'. In this case, Bitbake first builds recipe 'B' and then recipe 'A' E.g. You need 'dbus' to be built before 'wpa_supplicant'. RDEPENDS: When a recipe 'A' is RDEPENDS on recipe 'B'. In this case, Bitbake deploys 'B' on the target system when it deploys 'A'.  E.g. 'perf' RDEPENDS on 'bash' In other words, DEPENDS are those set of packages that should be available while building package, whereas RDEPENDS are set of packages that should be available during execution of the program.

PR, PN and PV Variable in Yocto

-
PN : Represents the name of the recipe. The name is usually extracted from the recipe file name. PR:  Represents the revision of the recipe. Default value for this revision is "r0". Subsequent revisions of the recipe conventionally will have "r1", "r2" and so on. PV:  Represents the version of the recipe. Normally extracted from the recipe file name. For example: ffmpeg_3.4.2.bb recipe. ${PN} : ffmpeg ${PV} : 3.4.2
