+# GNU nano (6.2) - nosearchwrap
+[![build](https://github.com/davidhcefx/GNU_nano_5.4_nosearchwrap/actions/workflows/build.yml/badge.svg)](https://github.com/davidhcefx/GNU_nano_5.4_nosearchwrap/actions/workflows/build.yml)
+
+- While performing textual search, many editors, for instance [Sublime](https://www.sublimetext.com/), support toggling the option **Wrap**, which is to wrap past end-of-file and proceed searching. It will be nice if Nano can have this too!
+
+
+### New rcfile option:
+```
+set nosearchwrap
+    Don't wrap around to the start or end of the buffer when performing search or replace.
+```
+
+### New program option:
+```
+--nosearchwrap
+    Don't wrap around to the start or end of the buffer when performing search or replace.
+```
+
+## How to compile
+
+*Please refer to [README.GIT](/README.GIT) for more details.*
+
+1. Install the dependencies: `apt install autoconf automake autopoint gcc gettext git groff make pkg-config texinfo`
+
+2. Run `./autogen.sh`.
+
+3. After that, just do the normal `./configure`, `make` and `make install`.
+
+
