Editor

Source code editor in pure Go.

About

This is a simple but advanced source code editor
As the editor is being developed, the rules of how the UI interacts will become more well defined.
Primarily developed and tested in Linux.
Works in MS Windows (native or xserver) and MacOS (xserver).

Features

Auto-indentation of wrapped lines.
No code coloring (except comments and strings).
Many TextArea utilities: undo/redo, replace, comment, ...
Handles big files.
Start external processes from the toolbar with a click, capturing the output to a row.
Drag and drop files/directories to the editor.
Detects if files opened are changed outside the editor.
Plugin support
- examples such as gotodefinition and autocomplete below.
Golang specific:
- Calls goimports if available when saving a .go file.
- Clicking on .go files identifiers will jump to the identifier definition (needs gopls).
- Debug utility for go programs (GoDebug cmd).
  - allows to go back and forth in time to consult code values.
Language Server Protocol (LSP) (code analysis):
- -lsproto cmd line option
- basic support for gotodefinition and completion
- mostly being tested with clangd and gopls
Inline complete
- code completion by hitting the tab key (uses LSP).

Installation

Instalation with git

Get with git the latest from the default master branch:

git clone https://github.com/jmigpin/editor

Build and run:

cd ./editor
go build
./editor

Windows platform compilation alternatives:

go build				# shows one console window (will be hidden, but makes a flash)
go build -ldflags -H=windowsgui		# hides the console window, but cmds will popup consoles
go build -tags=xproto 			# (not native, needs an x11 server to run)

Instalation with go tooling to be used as a library

go get -u github.com/jmigpin/editor

Please take care to distinguish between versions and ensure "go get" is actually getting the version you want.

This project is not using "vX" named directories. So version 3 is not in the directory "v3", nor is it named "*/v3" in imports. Versions are being updated using the same import path. The downside of this is that go websites (ex: pkg.go.dev) don't recognize versions tagged as 3 and above of this project.

Currently a release will be tagged with two tags that refer to the same version (ex: 3.3.0 and 1.3.3 is the same version).

Feel free to file an issue if you know of a better solution that doesn't require to use an import path of a directory that might not exist (case of using "vX" import paths).

The editor has no configuration file. Use it within a script with your preferences (example editor.sh):

#!/bin/sh
exec ~/path/editor \
--dpi=143 \
--fontsize=9 \
--colortheme=acme \
--commentscolor=0x008b00 \
--stringscolor=0x8b3100 \
--lsproto=go,.go,stdio,"gopls serve" \
--lsproto="cpp,\".c .h .cpp .hpp .cc\",stdio,clangd" \
--presavehook=go,.go,goimports \
--presavehook="cpp,\".c .h .cpp .hpp\",\"clang-format --someoption\"" \
"$@"

Basic Layout

The editor has a top toolbar and columns. Columns have rows. Rows have a toolbar and a textarea.

These row toolbars are also textareas where clicking (buttonRight) on the text will run that text as a command.

The row toolbar has a square showing the state of the row.

Toolbar usage examples

Commands in toolbars are separated by "|" (not to be confused with the shell pipe). If a shell pipe is needed it should be escaped with a backslash.

All internal commands start with an Uppercase letter. Otherwise it tries to run an existent external program.

Examples:

~/tmp/subdir/file1.txt | ls Clicking at ls will run ls at ~/tmp/subdir
~/tmp/subdir/file1.txt | ls -l \| grep fi Notice how "|" is escaped, allowing to run ls -l | grep fi
~/tmp/subdir/file1.txt Clicking at file1.txt opens a new row to edit the same file. Clicking at ~/tmp opens a new row located at that directory.
gorename -offset $edFileOffset -to abc Usage of external command with active row position as argument. gorename godoc, go tools.
guru -scope fmt callers $edFileOffset Usage of external command with active row position as argument. guru godoc, go tools.
grep -niIR someword Grep results with line positions that are clickable.
xdg-open $edDir Open favorite external application with active row directory.
xterm Open an xterm at the active row directory.
$font=mono Use monospaced font in this row textarea (see more at internal variables).

Commands

Toolbar commands

ListSessions: lists saved sessions
SaveSession <name>: save session to ~/.editor_sessions.json
DeleteSession <name>: deletes the session from the sessions file

Row toolbar commands

These commands run on a row toolbar, or on the top toolbar with the active-row.

NewFile <name>: create (and open) new file at the row directory. Fails it the file already exists.
Save: save file
Reload: reload content
CloseRow: close row
CloseColumn: closes row column

RuneCodes: output rune codes of the current row text selection.
FontRunes: output the current font runes.
OpenExternal: open the row with the preferred external application (ex: useful to open an image, pdf, etc).
OpenFilemanager: open the row directory with the external filemanager.
OpenTerminal: open the row directory with the external terminal.
LsprotoCloseAll: closes all running lsp client/server connections. Next call will auto start again. Useful to stop a misbehaving server that is not responding.
LsprotoRename <new-name>: Renames the identifiers under the text cursor using the loaded lsp instance. Uses the row/active-row filename, and the cursor index as the "offset" argument.
LsprotoCallers: lists callers of the identifier under the text cursor using the loaded lsp instance. Uses the row/active-row filename, and the cursor index as the "offset" argument. Also known as: call hierarchy incoming calls.
LsprotoCallees: lists callees of the identifier under the text cursor using the loaded lsp instance. Uses the row/active-row filename, and the cursor index as the "offset" argument. Also known as: call hierarchy outgoing calls.
LsprotoReferences: lists references of the identifier under the text cursor using the loaded lsp instance. Uses the row/active-row filename, and the cursor index as the "offset" argument.
GoRename [-all] <new-name>: Renames the identifier under the text cursor. Uses the row/active-row filename, and the cursor index as the "offset" argument. Reloads the calling row at the end if there are no errors.
- default: calls gopls (limited scope in renaming, but faster).
- -all: calls gorename to rename across packages (slower).
GoDebug <command> [arguments]: debugger utility for go programs (more at commands:godebug)
GoDebugFind <string>: find string in current selected annotation. Useful to rewind the annotations to the desired point.
GoDebugTrace: print all current callers that have not returned. Useful to aid in finding deadlocks.

Row name at the toolbar (usually the filename)

Clicking on a section of the path of the filename will open a new row with that content. Ex: if a row filename is "/a/b/c.txt" clicking on "/a" will open a new row with that directory listing, while clicking on "/a/b/c.txt" will open another row to edit the same file.

Textarea commands

OpenSession <name>: opens previously saved session
<url>: opens url in preferred application.
<filename(:number?)(:number?)>: opens filename, possibly at line/column (usual output from compilers). Check common locations like $GOROOT and C include directories.
- If text is selected, only the selection will be considered as the filename to open.
<identifier-in-a-.go-file>: opens definition of the identifier. Ex: clicking in Println on fmt.Println will open the file at the line that contains the Println function definition.

Commands: GoDebug

Output of GoDebug -help:

Usage:
	GoDebug <command> [arguments]
The commands are:
	run		build and run program with godebug data
	test		test packages compiled with godebug data
	build 	build binary with godebug data (allows remote debug)
	connect	connect to a binary built with godebug data (allows remote debug)
Env variables:
	GODEBUG_BUILD_FLAGS	comma separated flags for build
Examples:
	GoDebug run
	GoDebug run -help
	GoDebug run main.go -arg1 -arg2
	GoDebug run -paths=dir1,file2.go,dir3 main.go -arg1 -arg2
	GoDebug run -tags=xproto main.go
	GoDebug run -env=GODEBUG_BUILD_FLAGS=-cover main.go
	GoDebug run -network=ws -startexec=false -env=GOOS=js:GOARCH=wasm -o=static/main.wasm client/main.go
	GoDebug test
	GoDebug test -help
	GoDebug test -run=mytest -v
	GoDebug test a_test.go -test.run=mytest -test.v -test.count 5
	GoDebug build -help
	GoDebug build -addr=:8078 main.go
	GoDebug build -network=ws -addr=:8078 -env=GOOS=js:GOARCH=wasm -o=static/main.wasm client/main.go
	GoDebug connect -help
	GoDebug connect -addr=:8078
	GoDebug connect -network=ws -addr=:8078
	GoDebug connect -network=auto --continueserving

Output of GoDebug run -help:

Usage of GoDebug run:
  -addr string
    	address to transmit debug data
  -editorisserver
    	run editor side as server instead of client (default true)
  -env string
    	string with env variables (ex: "a=1:b=2:...")
  -network string
    	protocol to use to transmit debug data: [tcp, ws, unix, auto]. Option 'auto' detects a tcp client request to auto upgrade to http/websocket. Ex: useful to alternate between a debug session for a server (tcp) and a brower (websocket), without restarting the godebug cmd (use with -continueserving).
  -nodebugmsg
    	omit debug messages
  -o string
    	output filename
  -paths string
    	comma-separated string of dirs/files to annotate (also see the "//godebug:annotate*" source code directives to set files to be annotated)
  -sbr
    	Stringify bytes/runes as string (ex: [97 98 99] outputs as "abc") (default true)
  -srclines
    	add src reference lines to the compilation such that in case of panics, the stack refers to the original src file (default true)
  -startexec
    	start executable; useful to set to false in the case of compiling for js/wasm where the browser is the one starting the compiled file (default true)
  -syncsend
    	Don't send msgs in chunks (slow). Useful to get msgs before a crash.
  -toolexec string
    	a program to invoke before the program argument. Useful to run a tool with the output file (ex: wine)
  -usepkglinks
    	Use symbolic links to some pkgs directories to build the godebug binary. Helps solving new behaviour introduced by go1.19.x. that fails when an overlaid file depends on a new external module. (default true)
  -verbose
    	print extra godebug build info
  -work
    	print workdir and don't cleanup on exit

Annotate files

By default, the main file will be annotated. Other files/directories can be added with the -dirs and -files command line options, or by inserting one of the following comments in the code (notice the lack of space after "//"):

 //godebug:annotateoff		# disable annotating
 //godebug:annotateblock
 //godebug:annotatefile
 //godebug:annotatepackage
 //godebug:annotatemodule
 //godebug:annotateimport 	# use before an "import" line
 
 # or specify a target
 //godebug:annotatefile:<file> 	# absolute or relative to the current
 //godebug:annotatepackage:<pkg-path>
 //godebug:annotatemodule:<pkg-path> 	# any pkg path inside will annotate all
 
 # example:
 //godebug:annotatepackage:golang.org/x/tools/godoc/util

The annotator will detect these comments and annotate accordingly.

Packages located in $GOROOT are not annotated.

Higher level //godebug:* comments will override lower ones.

Example on how to bypass loops that would become too slow with debug messages being sent:

 //godebug:annotateoff	// don't annotate arg "v1"
 func fn(v1 int){
 	//godebug:annotateblock		// re-enable annotations
 	a:=0 // annotated
 	if a==0{
 		a++ // annotated
 		//godebug:annotateoff
 		a+=2 // *not* annotated
 		a+=3 // *not* annotated
 		for i:=0; i<10000;i++{
 			// *not* annotated
 		}
 	}
 	println(a) // annotated, not part of the disabled block
 }

Also, to improve on the String() limitation:

 type myint int
 func (v myint) String() string {
 	return f1(v)
 }
 // would cause endless loop with godebug calling t.String() at arg `v`
 // but not if it the annotations are off
 //godebug:annotateoff
 func fn(v myint) string { 
 	return fmt.Sprintf("%d", v) 
 }

Limitations:
- String() and Error() methods are not annotated to avoid endless loops (the annotation would recursively call the method again).
  - NOTE: The latest annotator annotates String() and Error() at the cost of not calling these methods to produce the debug msgs themselves. So the debug msgs will not show the String() output but simply the content of the variable. This will later be possible to use again with a command line option, with which these methods will then not be annotated to avoid endless loops.
Notes:
- Use esc key to stop the debug session. Check related shortcuts at the key/buttons shortcuts section.
- Supports remote debugging (check help usage with GoDebug -h).
  - The annotated executable pauses if a client is not connected. In other words, it stops sending debug messages until a client connects.
  - A client can connect/disconnect any number of times, but there can be only one client at a time.
- Example usage of setting the env var in a godebug session:
```
 GoDebug run -env=GO111MODULE=off main.go
```
  The example below builds a binary for windows in another platform, for later remote debug:
```
 GoDebug build -env=GOOS=windows -addr=:8008 main.go
 ... (copy the binary to the target platform and run it) ...
 GoDebug connect -addr=:8008
```

Internal variables

~<digit>=path: Replaces long row filenames with the variable. Ex.: a file named /a/b/c/d/e.txt with ~0=/a/b/c defined in the top toolbar will be shortened to ~0/d/e.txt.
$font=<name>[,<size>]: sets the row textarea font when set on the row toolbar. Useful when using a proportional font in the editor but a monospaced font is desired for a particular program output running in a row. Ex.: $font=mono.
$scrollMode={auto}: if the current bottom of the content is visible, auto scroll down when new content is added (ex: a cmd output).
$termFilter: same as $terminal=f
$terminal={f,k}: enable terminal features.
- f: Filter (remove) escape sequences from the output. Currently only the clear display sequence is interpreted in this mode which clears the output (usefull for running programs that want to discard old ouput).
- k: redirect keyboard input to the running program to enable reading from standard input. Note: typing keys will not be seen in the textarea unless the running program outputs them (exceptions: "\n") .

Environment variables set available to external commands

$edName: row name.
$edDir: row directory.
$edFileOffset: filename with offset position from active row cursor. Ex: "filename:#123".
$edFileLine: index line from active row cursor (1-based). Ex: "12".
$edFileWord: word at index from active row cursor. Ex: "myvar". Usage ex: use go doc $edFileWord with cursor at a receiver variable.
$<name>=<string>: set custom variable in a row toolbar to be set in the environment when running an external command.
Example row toolbar:
```
 $myprog="a.out -arg1"
 $myprog -arg2 | echo a${myprog}b
```
Clicking on $myprog -arg2 will have the shell run a.out -arg1 -arg2.
Clicking on echo a${myprog}b will result in echoing aa.out -arg1b.

Row states

background colors:
- blue: row file has been edited.
- orange: row file doesn't exist.
dot colors:
- black: row currently active. There is only one active row.
- red: row file was edited outside (changed on disk) and doesn't match last known save. Use Reload cmd to update.
- blue: there are other rows with the same filename (2 or more).
- yellow: there are other rows with the same filename (2 or more). Color will change when the pointer is over one of the rows.

Plugins

Plugins allow extra functionality to be added to the editor without changing the binary.

A plugin can be compiled and run with (will output a *.so):

go build -buildmode=plugin plugin1.go
go build -buildmode=plugin plugin2.go
editor --plugins plugin1.so,plugin2.so

Functions that can be implemented by a plugin are (subject to changes - work-in-progress ):

func OnLoad(ed *core.Editor)
func AutoComplete(ctx context.Context, ed *core.Editor, cfb *ui.ContextFloatBox) (err error, handled bool) // error` is only considered if `handled` is true
func ToolbarCmd(ed *core.Editor, erow *core.ERow, part *toolbarparser.Part) bool

Note that plugins might need to be recompiled everytime there are changes in the libraries provided by the editor.

Editor events currently implemented (subject to changes - work-in-progress ):

PostNewERowEEventId // on erow creation
PostFileSaveEEventId // after a file is saved
PreRowCloseEEventId // before a row is closed
RowStateChangeEEventId // on row state change (duplicate rows also emit).

Plugins located at: ./plugins.

gotodefinition_godef.go: plugin that shows how to override the textarea click action and use godef instead of the default.
autocomplete_gocode.go: plugin that shows a context with suggestions for .go files (uses gocode).
rownames.go: example plugin that shows how to access row names.
eevents.go: example plugin on how to access editor events.

Row placement algorithm

When a new row is created, it is placed either below the current row (measuring available space), or in a "good position".

The "good position" measures the available space between all rows, and uses the position with the most space.

The measuring of space is done as follows:

if the cursor is visible, measure space after visible cursor to the end of the textarea and use it if not smaller than two lines in height, otherwise use 2)
about 2/3 of the textarea
