Edit
Edit the current read only text.
View
View the current file read only.
Save
Save the current file if modified.
New
Start a new empty file. Use the Save as item to save the new file.
Open
Choose a file to open from the chooser dialog that pops up. The parent folder will be the first in the list. See File Chooser. The file will initially be read-only. Touch the Edit toolbar item to enable editing.
Open recent
Choose a file from the list that pops up. As above the file will initially be read only. The last entry, Clear list, will clear the list.
Save as
Enter a new file name in the dialog that pops up. Absolute names
starting with a slash '/' will be saved in that exact path if
possible. Names without a starting slash will be saved relative to the
main public folder, /sdcard/
, or /storage/emulated/0/
.
Search
Enter search text in the field that pops up in the toolbar. The first matching item will be highlighted. Use the search button in the keyboard for find next. The exact regular expression syntax used is in the android documentation for Pattern.
Find all
You may find all recent files that contain the current search text. This menu item will only appear while the search widget is active. A dialog will pop up with a list of matching files. Touch an entry to open that file. You may repeat this or refine the search text to find the desired file.
View markdown
You will be prompted to choose a viewer for an html file containing the encoded markdown from the current open file. If the text contains no markdown the result will be the same text.
Highlight syntax
If the current open file is a C, C++, Objective C, Go, Java, Javascript, Python, Shell script, Swift, CSS, HTML or Markdown file, the keywords, classes comments, strings, etc will be highlighted. See Syntax Highlighting.
Mode line
If a line of text is found within the first or last two or three lines of the file which matches the mode line pattern, the mode of the editor will be changed after the file is loaded. See Mode line.
# ed: [[no]vw] [[no]ww] [[no]sg] [[no]hs] [th:l|d|r] [ts:l|m|s] [tf:m|p]
Extended selection
If the file being edited is not a plain text file, selections created by double tapping or long touching on the text will be extended to enclosing delimiters (brackets, quotes) on the same text line.
Unsaved file
If you touch the new, back or open button, and the current file has been modified, you will be prompted whether you want to save it, else the editor will just exit or open a file chooser. The current file may be saved on app pause using the menu option. The scroll position and name will be remembered for the last 10 files opened.
Changed file
If a file has changed in storage while it was open in the editor, if you attempt to save it, or the app is resumed, you will be prompted whether to overwrite or reload the file.
Default file
If there is no open file any text entered will by default be saved in
Documents/Editor.txt
. This file will be loaded on start if it
exists. Use the Save as
menu item to save it elsewhere.
Shared file
Text files opened or shared by another app may be viewed and
edited. Some apps may share files or text using a content
URI that
is not resolvable to a path to a file in storage. In that case the
editor will read the file into the default file. The default file in
storage will not be overwritten. The Save item will save the file
in the original location if possible. Use the Save as menu item to
save the file elsewhere.
SD cards
Android allows removable SD cards to be used like a USB stick or as part of the device storage. Editing files on a removable SD card not part of the device storage may work on some devices, but is not supported.
