Bug ID: 503874
Summary: CLang Format Full File does not work on open tabs
which have not been saved
Classification: Applications
Product: kate
Version: 25.04.0
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: kwrite-bugs-n...@kde.org
Reporter: kdmw....@tuta.io
Target Milestone: ---
SUMMARY
In Kate there is a tool under Tools > External Tools > Tools > CLang Format
Full File. This tool is very handy to beautify code like JSON blocks or JS code
or other pieces of code. However this requires that the code snippet be saved
as a file. Only then it works. It does not work on open tabs which have not
been saved as a file. In such tabs, i.e. open tabs which have not been saved as
a file, even selecting the code snippet and trying to run the "CLang Format
Full File" does not work
STEPS TO REPRODUCE
1. Launch Kate.
2. Create a new file, by pressing the key combination CTRL+N or Selecting the
menu option File > New. It will open a new tab with the name "Untitled" or
"Untitled (2)" or "Untitled (3)" or something similar.
3. Copy a JSON code snippet or any other C/C++ code snippet and paste it in the
tab that was opened in step number 2.
4. With the tab opened in step number 2 in focus go to the menu option Tools >
External Tools > Tools > CLang Format Full File. See the observed result and
expected result
5. With the tab opened in the step number 2 in focus select only the code
snippet that was pasted in step number 3. Do not select any other code or text.
go to the menu option Tools > External Tools > Tools > CLang Format Full File.
See the observed result and expected result
OBSERVED RESULT
The following are the results that are observed in the Output section.
[External Tools Info] Running Clang Format Full File: clang-format -i
[External Tools Warning] Data written to stderr:
error: cannot use -i when reading from stdin.

-assume-filename= with input %{Document:Selection:Text}
[External Tools Error] Data written to stderr:
error: empty filenames are not allowed
Clang Format Selected Text finished with exit code 1
EXPECTED RESULT
The code should be beautified or formatted as per the CLang specs.
